Ⅰ 九年级英语基本语法知识
呵呵 希望对你有所帮助 祝楼主进步哈
By是个很常用的介词(有时也用作副词),在初中英语中的用法有以下几种: 1.意为“在……旁”、“靠近”。如: Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞,有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如: Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲? 3.表示方法、手段,可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如: The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激,于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如: One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。 否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
(4)used to 可以和be, have 以及其他状态动词连用,描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员,但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short. 马力奥过去总是很矮。Amy used to be outgoing. 爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法 英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
一、被动语态的句式变化:
Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
定语从句
1. who 指人,作主语或宾语 (作宾语可省略)
The man who I talked with is our teacher.
A person who steals things is called a thief.
2. whom指人,作宾语 (作宾语可省略,如介词提前则不能省)
The man (whom/who) I nodded to is Mr. Li.
The man to whom I nodded is Professor Li.
3. which 指物,作主语或宾语 (作宾语可省略, 如介词提前则不能省)
These are the trees which were planted last year.
This recorder (which) he is using is made in Japan.
Is this the library (which) you borrow books from?
Is this the library from which you borrow books?
4. that 指人/物,作主语或宾语 (作宾语可省略)
A plane is a machine. It can fly.→A plane is a machine that can fly.
He is the man. I told you about him. →He is the man (that) I told you about.
The scientist is very famous in the world. We met her yesterday.
↓
The scientist Ø we met yesterday is very famous in the world.
who
whom
that
The dress is new. She is wearing it.
↓
The dress that she is wearing is new.
which
Ø
(3) He is the kind person. I have ever worked with him.
↓
He is the kind person that I have ever worked with.
who
whom
Ø
This is the best film. I have ever seen this film.
↓
This is the best film that I have ever seen.
Ø
在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…

被动语态
被动语态基本用法:当句子的主语是动作的执行者时,谓语的形式是主动语态。当句子的主语是动作的承受者时,谓语要用被动语态。被动语态由助动词be+过去分词构成,时态通过be表现出来。
被动语态基本结构:be+及物动词的过去分词 (如果是不用物动词,其过去分词应带有相应的介词)
各种时态的被动语态构成
一般现在时:S(主语)+am/is /are +P.P(动词的过去分词)
一般过去时:S+was/were +P.P.
情态动词:S+ can/may/must/should + be+ P.P.
一般将来时:S+ will+be+ P.P.
现在进行时:S+am/is /are+being +P.P
现在完成时:S+ have/has + been+ P.P.
过去进行时:S+ was/were+being+ P.P.
被动语态基本结构:be+及物动词的过去分词
(如果是不用物动词,其过去分词应带有相应的介词)
被动语态中的be 是助动词,有人称、数和时态的变化。
被动语态中动作的发出者或执行者做介词by的宾语,放在句末,by 表示“由,被”的意思
汉语中含有“据说”、“据悉”、“有人说”、“大家说”等时。例如:
It is believed that …… 人们认为 …… It is said that …… 据说 ……
It is thought that …… 人们认为 …… It is known that …… 众所周知 ……
It is reported that ……据报道 …… It is proved that ……据证明 ……
It is announced that ……据宣布 …… It is suggested that ……据建议 ……
It is requested that ……据要求 …… It is demanded that ……据要求 ……
典型例题
1、 These eggs ______ in the Gobi Desert by a group of scientists.
A. are founded B. were founded C. found D. were found
此题应该选用D项。从“ These eggs… ”中可知前面的主语是“find”动词的承受者,而 “…by a group of scientists.”更加证明了这一点,“ were founded”意思为“被成立”,故应该选用“were found”。
2、 I _____ a present by my father on my birthday every year.
A. give B. was given C. will be given D. am given
此题应该选用D项。从“by my father ”中可知前面的主语是“give”动词的承受者,而 “… . every year”证明了要用现在时态的被动语态结构,故应该选用“am given”。
3、 He was _________ in the open air just now .
A. hearing singing B. heard sing C. heard to sing D. hearing sing
此题应该选用C项。从“He was… ”中可知前面的主语是“hear ”动词的承受者,而 动词不定式当中的“hear sb do sth”在被动语态中要加“to ”,故应该选用“heard to sing”。
4、 Several man-made satellites ________ by China in the last few years.
A. have been sent up B. have sent up C. are sent up D. were sent up
此题应该选用A项。从“…by China in the last few years. ”中可知前面的主语是“ send up”动词的承受者,而 “in the last few years.”意思为“在过去的几年中”,应该用完成时态, 而不是过去时态,故应该选用“have been sent up”。
5、 Another new road ______in our home town next year.
A. will build B. is built C. will be built D. has been built
此题应该选用C项。从“…next year. ”中可知是将来时态,而前面的主语是“ Another new road”是“ build”动词的承受者,故应该选用“ will be built”。
Unit 10 By the time I got outside, the bus had already left
1. 过去完成时
(1) 构成:由助动词had + 过去分词 构成
否定式:had not + 过去分词 缩写形式:hadn’t
(2) 用法
过去完成时表示在过去某一时间或动作之前已经发生或完成了
的动作。
(3) 它所表示的时间是“过去的过去”。

2、The train ______ for a while when they got to the station.
A. had left B. had been away C. had gone D. has been away
此题应该选用B项。从“for a while ”中可知要用完成时态的持续性动

Unit 11 Could you please tell me where the restrooms are ?
1、宾语从句
A.宾语从句:宾语从句在复合句中作主句的宾语,引导宾语从句的关联词有that, if/whether, what, who, whose, which, why, when, where, how等。
1、连接词
1)由连接词that引导陈述句,在口语中that常省略。
eg. He said that he would like to see the headmaster.
2)由连接词whether/if引导一般疑问句,whether和if 常可互换,但下列场合一般用whether.
①介词后的宾语从句:I'm thinking of whether he'll come.
②与or not连用:I don't know whether I should go or not.
3)由连接代词what, who(whom,whose)which或连接副词when, where, why,how引导特殊疑问句。 eg. Do you know who/whom she is waiting for?
2、语序:
不管宾语从句是陈述句、一般疑问句或特殊疑问句,都要用陈述句语序,也就是说主谓次序不能颠倒。连接词+主谓结构
(1).Bill wanted to know who did this. (2).I don't know what's the matter with Bob?
(3).I don't know what's wrong with them?
3、时态:
一般说来,主从句时态要统一。如果主句是一般现在时,从句可根据需要用其它任何时态;如果主句是一般过去时,从句应该用相应的过去时态范畴(也就是用一般过去时,过去进行时,过去将来时,过去完成时)。
eg.①Lily wanted to know whether her grandma liked the handbag. ②I asked the teacher where we would have the meeting. ③Could you tell me how I can get to the zoo?
如果从句表明的是一个客观事实或真理,那么无论主句是什么时态,从句都只能用一般现在时。 eg. The teacher told us that light travels much faster than sound.
注意:在think后的宾语从句,如果需要表示否定意义,一般不在宾语从句中否定,而是在主句中否定。 eg. I don’t think that English is easy. I think that English is not easy. ( 误)
Could you tell me how to get to the park?
请你告诉我怎么才能去邮局好吗?中的how to get to the park
是疑问词与动词不定式连用,用作宾语,但不是宾语从句,可是
相当于how I can get to the park(宾语从句)如:
I don’t know how to solve the problem. ==
I don’t know how I can solve the problem.我不知道如何解决这个问题
Can you tell me when to leave? ==
Can you tell me when I ill leave? 你能告诉我什么时候离开?
Unit12 You are supposed to shake hands.
should have asked”是“情态动词+现在完成时”表示过去本应该做某事,事实上没有做
I find it difficult to remember everything.
形式宾语 真正宾语
常见的形式宾语有:
find / think + it/them +形容词 to do sth. 如:
I think it hard to study English.
Unit 13 Rainy days make me sad.
make sb./sth. + adj. 使某人(感到),使……处于某种状态
(make的宾语之后可跟名词,形容词,分词来充当宾语的补足语)
make sb. / sth. + do …使某人做某事(不能带不定式符号to)
make it 习惯用语,及时赶到,到达目的地
make of /from./out of
★Make of 原材料制成成品后,原材料未经任何化学变化,仍保持原有性质. 例如: The chair is made of wood. At first people believed that air was made of only one gas.★Make from 当原材料制成成品后,经过了化学变化,失去了原有性质.
make up of 常用于被动结构:be made up of相当于consist of(由…组成) make up from 由…所制造
Unit 14 Have you packed yet?
现在完成时是由“助动词have(has)+动词过去分词”构成。
用法: 1.表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,如:already, yet, ever, never, just, before, once, twice等连用,也可以和包括现在在内的时间状语,如these days, today, this year, so far等连用.eg.I have already posted the letter. (信已经不在我这儿了)
★注意:在这里要注意already和yet的辨析:
★①already通常用于肯定句。 I have already told him.我已经告诉他了. I have already put it in my suitcase. 我已经把它放进我的手提箱了.
★②yet常用于疑问句和否定句。 ----Have you watered the tree yet? 你浇树了吗? ----Yes,I have already watered it. 我浇了. ----Have you fed the dog? 你喂过狗了吗? ----No. I haven’t fed it yet.没有,我没喂. 2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从句, in the last ten years等,谓语只可用延续性动词.
解析: 1.英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或点动词),如begin,start,die,buy,leave, come等,表示动作的发生与结束于一瞬间完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句中.
eg. I've left Shanghai for three days.(×) I've been away from Shanghai for three days.( √ ).
I left Shanghai three days ago. ( √ ) It is /has been three days since I left Shanghai.( √ )
2.初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.终止性动词要表示持续时, 可用以下方法:
⑴.将时间状语改为时间段 + ago,句中谓语动词用一般过去时.
eg.我弟弟参军两年了. My brother joined the army two years ago.
⑵.若保留for+时间段,since+时间点/从句, 或用在 how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词
★常见终止性动词与延续性动词(或状态动词)的对应关系如下:
come/go/arrive/get/reach/move------be in/at open-----be open
die------be dead close----be closed become---be borrow---keep begin/start-----be on put on----wear leave-----be away (from)
buy-----have fall asleep----be asleep end/finish-----be over
catch a cold-----have a cold join the army----be in the army be a soldier
join the Party----be in the Party be a Party member
→My brother has been in the army for two years. →My brother has been a soldier for two years.
3.现在完成时中been to, gone to和been in/at been to去过某地,表示某人的一种经历,可以和once, twice, already, ever, never等连用.
4.现在完成时中的 for 与 since
for + 时间段 与延续性动词的现在完成时连用 since + 时间点/从句
I have kept the library book for a week.= I have kept the library book since a week ago. 5. It is /has been +一段时间 + since 从句.自从某事发生已有一段时间了. eg. It is /has been two years since my brother joined the army. 注意:1.since 引导的从句中动词用过去时
2.when 引导 的特殊问句不与现在完成时连用.
3.have got,has got 虽然是现在完成时,但have got=have has got==has

返回动词的时态目录
11.10 比较一般过去时与现在完成时
1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。
2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。
一般过去时的时间状语:yesterday, last week,…ago, in1980, in October, just now等,皆为具体的时间状语。
现在完成时的时间状语:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不确定的时间状语。
共同的时间状语:this morning, tonight, this April, now, already, recently, lately 等。
3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.。
一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如:
I saw this film yesterday. (强调看的动作发生过了)
I have seen this film. (强调对现在的影响,电影的内容已经知道了)
Why did you get up so early? (强调起床的动作已发生过了)
Who hasn't handed in his paper? (强调有卷子未交,疑为不公平竞争)
He has been in the League for three years. (在团内的状态可延续)
He has been a League member for three years. (是团员的状态可持续)
句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。
(错)Tom has written a letter to his parents last night.
(对)Tom wrote a letter to his parents last night.

11.11 用于现在完成时的句型
1)It is the first / second time.... that…结构中的从句部分,用现在完成时。例如:
It is the first time that I have visited the city. 这是我第一次访问这城市。
This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
注意:It was the third time that the boy had been late.
2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如:
This is the best film that I've (ever) seen. 这是我看过的最好的电影。
典型例题
(1) ---Do you know our town at all?
---No, this is the first time I ___ here.
A. was B. have been C. came D. am coming
答案B. This is the first time 后面所加从句应为现在完成时,故选B。
(2) ---Have you ____ been to our town before?
---No, it's the first time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。
注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
(错)I have received his letter for a month.
(对)I haven't received his letter for almost a month.
返回动词的时态目录
11.12 比较since和for
Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如:
I have lived here for more than twenty years.我住在这儿二十多年了。
I have lived here since I was born. 我从出生起就住在这儿了。
注意:并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years. (我现在已不在这里工作。)
I have worked here for many years.(现在我仍在这里工作。)
注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。
1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years.

11.13 since的四种用法
1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如:
I have been here since 1989. 1989起,我一直在这儿。
2) since +一段时间+ ago。例如:
I have been here since five months ago. 我在这儿,已经有五个月了。
3) since +从句。例如:
Great changes have taken place since you left. 你走后,变化可大了。
Great changes have taken place since we were here. 我们走后,变化可大了。
4) It is +一段时间+ since从句。例如:
It is two years since I became a postgraate student. 我考上研究生有两年了。

11.14 延续动词与瞬间动词
1) 用于完成时的区别
延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如:
He has completed the work. 他已完成了那项工作。 (表结果)
I've known him since then. 我从那时起就认识他了。(表经历)
2) 用于till / until从句的差异
延续动词用于肯定句,表示"做……直到……" 瞬间动词用于否定句,表示"到……,才……"。例如:
He didn't come back until ten o'clock. 他到10 点才回来。
He slept until ten o'clock. 他一直睡到10点。
典型例题
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。
2. ---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。
返回动词的时态目录
11.15 过去完成时
1) 概念:表示过去的过去
----|----------|--------|----> 其构成是had +过去分词构成。
那时以前 那时 现在
2) 用法
a. 在told, said, knew, heard, thought等动词后的宾语从句。例如:
She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。
b. 状语从句
在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如:
When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。
c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"。例如:
We had hoped that you would come, but you didn't. 那时我们希望你能来,但是你没有来。
3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如:
He said that he had learned some English before. 他说过他以前学过一些英语。
By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年,爱迪生开始自己谋生。
Tom was disappointed that most of the guests had left when he arrived at the party.
汤姆失望了,因为他到达晚会时,大部分客人已经走了。
典型例题
The students ___ busily when Miss Brown went to get a book she ___ in the office.
A. had written, left B,were writing, has left C. had written, had left D. were writing, had left
答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。
注意: had hardly… when 还没等…… 就……。例如:
I had hardly opened the door when I he hit me. 我刚打开门,他就打了我。
had no sooner…than 刚…… 就……。例如:
He had no sooner bought the car than he sold it. 他刚买了这辆车,转眼又卖了。

When she saw the mouse,she screamed. 她看到老鼠,就叫了起来。
My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子,我把它丢了。
2 ) 两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。例如:

九年级英语复习---语法讲解(1-7单元)
Unit1
By是个很常用的介词(有时也用作副词),在初中英语中的用法有以下几种: 1.意为“在……旁”、“靠近”。如: Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞,有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如: Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲? 3.表示方法、手段,可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如: The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激,于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如: One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。
否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
(4)used to 可以和be, have 以及其他状态动词连用,描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员,但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short.马力奥过去总是很矮。Amy used to be outgoing.爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
一、被动语态的句式变化: 以一般现在时和动词invite为例,列表说明被动语态的句式变化:
二、各种时态的被动语态结构总结如下: 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。一般现在时的被动语态为:主+am / is / are (not)+过去分词一般过去时的被动语态为:主+was / were +过去分词
例如:我们学过的was / were born 生于,就是一个被动语态.born是个过去分词(bear)-When were you born ? -I was born in 1989. 现在进行时被动语态的构成为: 主语+is / am / are + being +过去分词
现在完成时被动语态的构成为: 主语+have / has +been +过去分词
情态动词的被动语态: 情态动词+be+过去分词
一般将来时的被动语态: 主语+will +be +过去分词
过去将来时的被动语态: 主语+would / should + be +过去分词
过去进行时的被动语态: 主语+was / were + being +过去分词
过去完成时的被动语态: 主语+had + been +过去分词
三、被动语态的用法:(1)不知道或没有必要说明动作的执行者是谁,不用by+动作执行者短语 Football is played widely all over the world. 全世界都广泛地踢足球。
(2)强调动作的承受者,这时应用by短语。The bank was robbed yesterday afternoon. 昨天下午这家银行遭到抢劫。
(3)作客观说明时,常采用一种被动语态句型It is reported that about twenty children have died of flu in the USA.
据报道美国大约二十名儿童死于流感。
四、主动语态的句子变为被动语态的方法是:(1)把原句中的宾语变为主语(2)动词改为被动形式,即be+过去分词(3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。请看下表:
主动语态 被动语态
They make trains in Zhuzhou. They use this key for locking the classroom door.Many people speak English.He wrote a letter.They are building a road. Trains are made in Zhuzhou.This key is used for locking the classroom door(by them).English is spoken by many people.A letter was written by him.A road is being built (by them).
Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
“if”引导的条件句。
Unit5
It must be--- (肯定是,100%)
It might/could be… (有可能,20-80%)

Unit6
定语从句
1. who 指人,作主语或宾语 (作宾语可省略)
The man who I talked with is our teacher.
A person who steals things is called a thief.
2. whom指人,作宾语 (作宾语可省略,如介词提前则不能省)
The man (whom/who) I nodded to is Mr. Li.
The man to whom I nodded is Professor Li.
3. which 指物,作主语或宾语 (作宾语可省略, 如介词提前则不能省)
These are the trees which were planted last year.
This recorder (which) he is using is made in Japan.
Is this the library (which) you borrow books from?
Is this the library from which you borrow books?
4. that 指人/物,作主语或宾语 (作宾语可省略)
A plane is a machine. It can fly.→A plane is a machine that can fly.
He is the man. I told you about him. →He is the man (that) I told you about.
The scientist is very famous in the world. We met her yesterday.

↓

在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。
1.定语从句中that与who、which的区别
2.定语从句中关系词的省略
典型例题
1. The first job ________I found was to be a cleaner.
A. where B. why C. which D. that
解析:指事物的先行词前有序数词修饰时,只能用关系代词that。故本题的正确答案是D。
2. I don’t think history is as interesting as English.(改为同义词)
I think history is ___________ interesting _________ English.
解析:答案是:less; than。意思是“我认为历史不如英语有趣”。
3. The woman who is wearing the hat is my mother.(改为同义句)
The woman ________ the hat is my mother.
解析:读题后可知:上句含义是“戴帽子的那个妇女旭我的妈妈”,对应下句,可知空格处应填“戴”,故正确答案是in。
选择填空
1. The poor boy ________ lost both his parents last year is called Mike.
A.which B.what C.who D./
2. The bridge ________ has been there for nearly fifty years still looks nice.
A.which B.what C./ D.who
3. I’m one of the students _______well in English in my class.
A.who does B.who do C.which does D.who did
4. Is this factory ________ some foreign friends visited last Friday?

九年级英语复习---语法讲解(Units8-15)
Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…

他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。
否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。

本单元重点讲到了被动语态的用法英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
一、被动语态的句式变化: 以一般现在时和动词invite为例,列表说明被动语态的句式变化:
二、各种时态的被动语态结构总结如下: 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。一般现在时的被动语态为:主+am / is / are (not)+过去分词一般过去时的被动语态为:主+was / were +过去分词
例如:我们学过的was / were born 生于,就是一个被动语态.born是个过去分词(bear)-When were you born ? -I was born in 1989. 现在进行时被动语态的构成为: 主语+is / am / are + being +过去分词
现在完成时被动语态的构成为: 主语+have / has +been +过去分词
情态动词的被动语态: 情态动词+be+过去分词
一般将来时的被动语态: 主语+will +be +过去分词
过去将来时的被动语态: 主语+would / should + be +过去分词
过去进行时的被动语态: 主语+was / were + being +过去分词
过去完成时的被动语态: 主语+had + been +过去分词
三、被动语态的用法:(1)不知道或没有必要说明动作的执行者是谁,不用by+动作执行者短语 Football is played widely all over the world. 全世界都广泛地踢足球。
(2)强调动作的承受者,这时应用by短语。The bank was robbed yesterday afternoon. 昨天下午这家银行遭到抢劫。
(3)作客观说明时,常采用一种被动语态句型It is reported that about twenty children have died of flu in the USA.
据报道美国大约二十名儿童死于流感。
四、主动语态的句子变为被动语态的方法是:(1)把原句中的宾语变为主语(2)动词改为被动形式,即be+过去分词(3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。请看下表:
主动语态 被动语态
They make trains in Zhuzhou. They use this key for locking the classroom door.Many people speak English.He wrote a letter.They are building a road. Trains are made in Zhuzhou.This key is used for locking the classroom door(by them).English is spoken by many people.A letter was written by him.A road is being built (by them).
Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
“if”引导的条件句。

在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。
1.定语从句中that与who、which的区别
2.定语从句中关系词的省略
典型例题
1. The first job ________I found was to be a cleaner.
A. where B. why C. which D. that
解析:指事物的先行词前有序数词修饰时,只能用关系代词that。故本题的正确答案是D。
2. I don’t think history is as interesting as English.(改为同义词)
I think history is ___________ interesting _________ English.
解析:答案是:less; than。意思是“我认为历史不如英语有趣”。
3. The woman who is wearing the hat is my mother.(改为同义句)
The woman ________ the hat is my mother.
解析:读题后可知:上句含义是“戴帽子的那个妇女旭我的妈妈”,对应下句,可知空格处应填“戴”,故正确答案是in。
选择填空
1. The poor boy ________ lost both his parents last year is called Mike.
A.which B.what C.who D./
2. The bridge ________ has been there for nearly fifty years still looks nice.
A.which B.what C./ D.who

Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…

Ⅶ 初三英语语法点
独立主格结构
独立主格结构由名词或代词加上其他成分(分词、不定式、名词、代词、形容词、副词或介词短语)构成。
独立主格结构没有主语和谓语,所以在语法上不是句子。但多有名词或代词表示的逻辑主语,分词或不定式表示的逻辑谓语,有时还有其他修饰成分。(判断一个结构是否是句子的标准就是看看这个结构是否有谓语动词。)这种结构通常在句子中起方式、时间、原因、条件等状语或状语从句的作用,主要用于书面语。使用动词非谓语形式的独立主格结构可以改为句子形式(从句):独立主格结构加上连词,非谓语动词改为谓语动词形式,这样就成为从句了。
例如:
Today being Sunday, the library isn' t open.今天星期天,图书馆不开放。
(原因)改为从句:
As (Since) today is Sunday, the library isn' t open.
例如:
There being no buses,we had to take a taxi. 没有汽车了,我们只好坐出租车了。
Because there were no buses, we had to take a taxi.
The signal given,the bus started.信号发出后,公共汽车就启动了。
(时间)改为从句:
After the signal was given, the bus started.
The boy followed that man here,and climbed in,sword in hand.少年跟那个人到这里,并爬了进来,手里拿着剑。
The boy followed that man here,and climbed in,and had a sword in his hand.
The mid-term examination is over, the end-of-term examination to come two months later.期中考试结束了,两个月之后进行期末考试.
The mid-term examination is over, and the end-of-term examination is to come two months later.
Weather permitting, we' 11 visit the Great Wall.如果天气允许的话,我们就去参观长城。
If weather permits, we' 11 visit the Great Wall.
The boy followed that man here, and climbed in, sword in hand.少年跟那个人到这里,并爬了进来,手里拿着剑。(伴随状语)
上文例句中sword in hand是由“名词+介词短语”构成,表示伴随的情况。这种表示伴随情的独立主格结构,有时可以用with引出,二者的意思是一样的,with结构更加口语话,更加常用。
She left the office with tears in her eyes.她眼里含着泪水,离开了办公室。
The teacher walked into the classroom, with a ruler under his arm and some books in his hand.老师胳膊底下挟着一把尺子,手里拿着几本书,走进了教室。
The teacher walked into the classroom. He was holding a ruler under his arm and some books in his hand.
Tian' anmen Square looks magnificent with all the lights on.华灯齐放,天安门广场显得美丽动人。
With the boy leading the way, we found his house with no difficulty.由这孩子领路,我们毫不费劲地找到他的家。
With him to give us a lead, our team is bound to turn out well.有他给我们带头,我们对一定能搞好。

一致
英语的一致有三种:主谓一致,代词一致,肯定与否定一致
一、主语与谓语的一致
英语语法要求,主语如果是单数,谓语动词也要用单数形式;主语若是复数,谓语动词也要用复数形式
例如:
She likes to eat well.她好吃
We all like good food.我们都喜欢好饭菜。
Everybody was happy with the decision. 人人都对这个决定感到高兴。

His opinion and mine are different他的观点和我的是不同的。
Bob and Peter are deadly rivals. Bob和peter是死对头。
What she says and what she does are totally different. 她说的和做的完全不同。
但是如果and连接的是指一个单一概念时,谓语动词用单数。

All this effort and sacrifice has come to nothing. 所有这些努力和牺牲都白费了。

No boy and no girl has the right to refuse ecation. 男孩和女孩都没有拒绝教育的权利。
Man a man and man a woman was moved b this picture。许多男男女女都被这幅画感动。
2.如果主语是一个抽象概念(如不定式、动名词、主语从句等)谓语动词用单数形式。如果主语是用and连接的两个或多个抽象概念,谓语动词用复数形式。
如:Swimming jogging and cycling are all goad farms of sports exercises.游泳、慢跑和骑自行车都是很好的运动形式。
To live to eat is not a very goad attitude toward life. 活着就是为了吃不是好的生活态度。
To live to eat and to eat to live are very different attitudes toward life.
以what,who,why,haw, whether等wh一词引起的从句做主语时,谓语动词通常用单数;由and连接的两个主句如果指两件事,动词用复数。
例如:What he is doing is not clear yet他在干什么还不清楚
What he is doing and whether I know him are two different things.他在干什么和我是否认识他是两件不同的事。
What she told me is none of your business. 她和我说的什么用不着你管。
What she told me and what she told you are totally different things.
以what从句为主语的“主一系一表SVC"句型中,如果主句的表语是复数,主句谓语动词用复数形式;what从句本身是复数意义,主句谓语动词也可用复数。
如:What I need buy now are four tea cups and a pair of sports shoes.
我需要买的是四只茶杯和一双运动鞋。
What were thought to be five dogs were actually five sheep.
被认为是五条狗的东西实际上是五只羊。
3.集体名词family,class,crew(全体船员或机组人员),crowd, group, committee, audience, government, public, team, staff, population等做主语时,若作为一个整体看待,后面谓语动词用单数; 如就其中每一个成员来考虑时,则用复数。

4.不定代词either,neither,ever y,each,one,the other, another以及所有的复合不定代词作主语时,谓语动词只用单数,包括“every/each/no……and every/each/no……”作主语时。
如:Every/Each plane and every/each pilot is ready to take off.
每架飞机和每个飞行员都已准备好起飞。
No plane and no pilot is ready to take off.

Either day is OK. 两天中哪一天都行。
5. what,who,which,any,mare,some,half,mast,all,none.等代词可以是单数,也可以是复数,主要靠意思决定。但指不可数名词时作单数看待。
例如:Which is your book? Which are your books?
Here' s same mare (coffee). Here' re same more (tomatoes).
None of the books are/is easy enough for us.
Most of Most of
All of All of
Some of The money was stolen Some of The member was there.
Half of Half of
None of None of
Two thirds of Two third of
由Many a或mare than one所修饰的词做主语时,意义上虽然是复数,但谓语动词用单数形式。none在代表不可数的东西时总是看作单数.
如:Many a person is far his plan. 很多人赞成他的计划。
Mare than one people is against his plan. 不止一个人反对他的计划。
6.表示时间、重量、长度、价值等的单位名词,尽管是复数形式,如果作整体看待,动词都用单数形式。如果看作组成该数量的一个一个的个体,则动词用复数。

The difficulty we do at once. The impassible takes a little loner.
困难的事情我们马上做。不可能的事情需要稍微长一点的时间。
还有the unknown(未知的事物),the unexpected(出乎意料的事),等等。
8. 如果主语由"a kind/sort/type of this kind/sort/type of +名词”组成,不管名词是单数还是复数,动词通常用单数。
如:This kind of man annoys me. =This kind of men annoys me. 这种人让我烦。
This kind of apple is very expensive. = This kind of apples is…这种苹果很贵。
类似的还有:a portion of(一部分),a series of(一系列),a pile of(一堆),a panel of (一个小组委员会),
如:A series of accidents has happened here. 这里发生过一系列事故。
9. Means作“方法、手段”讲时,单复数同形,其前面有each, every, neither, either,等单数a念的定语时,谓语动词用单数;若有all, both,these等复数概念的定语时谓语动词用复数。

All possible means have/Every possible means has been tried.所有的方法都试过了。
三、就近一致
1.当主语由either...... or. neither...... nor , not only ...... but(also) 或or连接时,谓语动词通常和最临近的那个主语一致。
例如:Either you or he is to do the work. 不是你就是他来做这件事。
Not only you but also Tom often comes late to class. 不光是你,汤姆上课也迟到。
Neither the children nor the teacher knows anything about it.
孩子们和老师都不知道这件事。
2.当there be结构后面有并列主语时,谓语也和最临近的那个一致。
如:There is a dictionary and many books on the table.
桌子上有一本词典和许多本书。
There' re ten chairs and a table in the house.
屋子里有十把椅子和一张桌子。
Here is a pen, a few envelopes and same paper far you.
这儿有一支笔,几个信封和一些纸给你。
这种就近一致的情况在非正式文体中越来越普遍。但在下列情况不提倡模访。
如:Where is your mother and sisters?
你妈妈和你姐妹到哪儿去了?
Is your sister and her husband coming to see you?
你姐姐和姐夫要来看你吗?
One in ten are expected to take part in the contest.
预计每十个人就有一个要来参加这次比赛。
3.做主语的名词或代词后接with,together with,along with,as well as等短语时,谓语动词一般和前面名词或代词一致。这些短语前后可用可不用逗号。
如:A woman with a baby is coming to the hospital
一个妇女抱着个婴儿正向医院走来。
The girl, as well as the bays , has learned to drive a car.
这个姑娘和那些那孩子一样也学会了开汽车。
二、代词一致
代词一致是指句子中代词应在数、性、人称等方面彼此保持一致,
如:One must do one' s best to increase proction.
Everybody talked at the tap of his/their voice.
If anyone calls, tell him I' 11 be back in a moment. (him也可用him or her代替)
在写作中,如果表示不定的人,可以用you, we, one等,需要注意的是:同一篇文章中,只用同一个不定代词,而且所有格要与其一致。
三、肯定与否定一致
下列形容词、副词、代词从肯定句变成否定句时,须作相应的变化:
肯定句 否定句
We've had some money. We haven't had any money.
I was talking to someone I wasn't talking to anyone.
They sometimes visit us. They rarely (never, seldom) visit us.
He has arrived already. He hasn't arrived yet.
Li is coming too. Li isn't coming either.
Both of us are going. Neither of us are going.
He likes both of them. He doesn't like either of them.
注意:“so/neither+助动词/情态动词+名词/代词”结构中须用倒装语序,
如:My wife likes classical music very much and so do.
She doesn' t like jazz and neither do.

Ⅸ 初三英语语法知识点(只问一个很简单的)要快
1. be used to do是被动语态,表示“抄被用作…” 例如:The knife is used to cut things.小刀是被用作切东西的。
2. used to do是主动语态,意思是“过去常常做某事”,表示现在不这样做了。
例如:He used to get up early.他过去常常早起。
