1. 求取：初三英语全部语法知识
. 一般现在时的用法
1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。
时间状语： every…, sometimes, at…, on Sunday
I leave home for school at 7 every morning.
2) 客观真理，客观存在，科学事实。
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中。
Pride goes before a fall. 骄者必败。
注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。
例：Columbus proved that the earth is round..
4) 现在时刻的状态、能力、性格、个性。
I don’t want so much.
Ann Wang writes good English but does not speak well.
比较：Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
2. 一般过去时的用法
1）在确定的过去时间里所发生的动作或存在的状态。
时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。
Where did you go just now?
2）表示在过去一段时间内，经常性或习惯性的动作。

It is time for you to go to bed. 你该睡觉了。
It is time you went to bed. 你早该睡觉了。
would (had) rather sb. did sth. 表示’宁愿某人做某事’
I’d rather you came tomorrow.
4) wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等。
I thought you might have some. 我以为你想要一些。
比较：
一般过去时表示的动作或状态都已成为过去，现已不复存在。
Christine was an invalid all her life.
(含义：她已不在人间。)
Christine has been an invalid all her life.
(含义：她现在还活着)
Mrs. Darby lived in Kentucky for seven years.
(含义：达比太太已不再住在肯塔基州。)
Mrs. Darby has lived in Kentucky for seven years.
( 含义：现在还住在肯塔基州，有可能指刚离去)
注意： 用过去时表示现在，表示委婉语气。
1）动词want, hope, wonder, think, intend 等。
Did you want anything else?
I wondered if you could help me.
2）情态动词 could, would.
Could you lend me your bike?
3. used to / be used to
used to + do："过去常常"表示过去习惯性的动作或状态，但如今已不存在。
Mother used not to be so forgetful.
Scarf used to take a walk. (过去常常散步)
be used to + doing： 对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。
He is used to a vegetarian diet.
Scarf is used to taking a walk.(现在习惯于散步)
典型例题
---- Your phone number again? I ___ quite catch it.
---- It’s 69568442.
A. didn’t B. couldn’t C. don’t D. can’t
答案A. 本句虽没有明确的时间状语，但从语意上看 出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。
4. 一般将来时
1) shall用于第一人称，常被will 所代替。
will 在陈述句中用于各人称，在争求意见时常用于第二人称。
Which paragraph shall I read first.
Will you be at home at seven this evening?
2) be going to +不定式，表示将来。
a. 主语的意图，即将做某事。
What are you going to do tomorrow?
b. 计划，安排要发生的事。
The play is going to be proced next month。
c. 有迹象要发生的事
Look at the dark clouds, there is going to be a storm.
3) be +不定式表将来，按计划或正式安排将发生的事。
We are to discuss the report next Saturday.
4) be about to +不定式，意为马上做某事。
He is about to leave for Beijing.
注意：be about to 不能与tomorrow, next week 等表示明确将来时的时间状语连用。
5. be going to / will
用于条件句时， be going to 表将来
will 表意愿
If you are going to make a journey, you’d better get ready for it a s soon as possible.
Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.
6. be to和be going to
be to 表示客观安排或受人指示而做某事。
be going to 表示主观的打算或计划。
I am to play football tomorrow afternoon. (客观安排)
I’m going to play football tomorrow afternoon. (主观安排)
7. 一般现在时表将来
1）下列动词：come, go, arrive, leave, start, begin, return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus star? It stars in ten minutes.
2）倒装句，表示动作正在进行，如：
Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3）在时间或条件句中。
When Bill comes (不是will come), ask him to wait for me.
I’ll write to you as soon as I arrive there.
4）在动词hope, take care that, make sure that等后。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
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。
It is the first time that I have visited the city.
It was the third time that the boy had been late.
2）This is the… that…结构，that 从句要用现在完成时.
This is the best film that I’ve (ever) seen.
这是我看过的最好的电影。
This is the first time (that) I’ve heard him sing. 这是我第一次听他唱歌。
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。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。
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.
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。
I have lived here for more than twenty years.
I have lived here since I was born..
My aunt has worked in a clinic since 1949.
Some new oilfields have been opened up since 1976.
I have known Xiao Li since she was a little girl.
My brother has been in the Youth League for two years.
I have not heard from my uncle for a long time.
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。)
小窍门： 当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。
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.
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)。
I have been here since 1989.
2) since +一段时间+ ago
I have been here since five months ago.
3) since +从句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4) It is +一段时间+ since从句
It is two years since I became a postgraate student.
被动语态的几种类型
1）主语句中有一个宾语的被动语态，如：
He saw her in the shop yesterday.
She was seen in the shop yesterday.
2) 主语有两个宾语的被动语态
Li Lei gave me a chemistry book.
I was given a chemistry book by Li Lei.
A chemistry book was given to me by Li Lei.
3）主动句中含宾语补足语的句子的被动语态
若宾语补足语是不带to 的不定式，变为被动语态时，该不定式前要加"to"。此类动词为
感官动词：feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teacher made me go out of the classroom.
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground.
--> He was seen to play football on the playground.
若宾语补足语是带to的不定式，那么被动语态仍保留to:
Mother told me not to be late
I was told not to be late by mother.
5）情态动词+ be +过去分词，构成被动语态。
Coal can be used to proce electricity for agriculture and instry.
6）表示"据说"或"相信" 的词组
believe, consider, declare, expect, feel , report, say, see, suppose, think, understand
It is said that… 据说
It is reported that… 据报道
It is believed that… 大家相信
It is hoped that… 大家希望
It is well known that… 众所周知
It is thought that… 大家认为
It is suggested that… 据建议
It is taken granted that… 被视为当然
It has been decided that… 大家决定
It must be remember that…务必记住的是
It is said that she will leave for Wuhan on Tuesday.
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。
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……"
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
. 不定式作宾语
1) 动词+ 不定式
afford aim appear agree arrange ask be decide bother care choose come dare demand desire determine expect elect endeavor hope fail happen help hesitate learn long mean manage offer ought plan prepare pretend promise refuse seem tend wait wish undertake
举例：
The driver failed to see the other car in time.
司机没能及时看见另一辆车。

2. 不定式作补语
1) 动词+宾语+不定式(to do)
advise allow appoint believe cause challenge command compel consider declare drive enable encourage find forbid force guess hire imagine impel ince inform instruct invite judge know like order permit persuade remind report request require select send state suppose tell think train trust understand urge warn
例句：
a. Father will not allow us to play on the street.
父亲不让我们在街上玩耍。
b. We believe him to be guilty.
我们相信他是有罪的。
Find 的特殊用法：
Find 后可用分词做宾补，或先加形式宾语，再加形容词，最后加带to 的动词不定式。find后也可带一个从句。此类动词还有get，have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例题:
The next morning she found the man ___ in bed，dead.
A. lying B. lie C. lay D. laying
答案：A.find的宾语后面，用分词或分词短语，起宾语补足语作用。现在分词表达主动，也表达正在进行，过去分词表达被动。
2) to + be 的不定式结构，作补语的动词。
Acknowledge, believe, consider, think, declare(声称), discover, fancy(设想), feel find, guess, judge, imagine, know, prove, see(理解), show, suppose, take(以为), understand
We consider Tom to be one of the best students in our class.
我们认为汤姆是班上最好的学生之一。
典型例题
Charles Babbage is generally considered ___ the first computer.
A. to invent B. inventing C. to have invented D. having invented
答案：A. 由consider to do sth. 排除B、D。. 此句只说明发明这一个事实，不定式后用原形即可。而C为现在完成时，发明为点动词一般不用完成时，且此处也不强调对现在的影响，因此不选C。
3) to be +形容词
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean…
The book is believed to be uninteresting.
人们认为这本书没什么意思。
4) there be+不定式
believe, expect, intend, like, love, mean, prefer, want, wish, undrstand

Mary took him as her father . 玛丽把他当作自己的父亲。
. 不定式作主语
1） It’s easy (for me) to do that.我做这事太容易了

例句:

注意：1) 其他系动词如，look，appear等也可用于此句型
2) 不定式作为句子成分时，动词用单数形式。
3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型
(对)To see is to believe. 百闻不如一见。
(错)It is to believe to see.
4. It’s for sb.和 It’s of sb.
1）for sb. 常用于表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：
It’s very hard for him to study two languages. 对他来说学两门外语是很难的。
2）of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。
It’s very nice of you to help me. 你来帮助我，你真是太好了。
for 与of 的辨别方法：
用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：
You are nice. (通顺，所以应用of)。
He is hard. (人是困难的，不通，因此应用for。)
3) 祁使句（Imperative Sentence）
祈使句往往是用来表示说话人的请求、命令、要求、建议，等等。祈使句的主语常被省略，因为这个主语很明确地是听话人"you"。当然，有时为了强调或表示某种感情，句子也会带上主语。
祈使句的谓语用动词原形；它的否定形式是句首用Don't + 动词原形，或是Not to + 动词原形。例如：
Be quiet , please ! （大家）请安静。
Stand up ! 起立！
Don't smoke in the office . 请不要在办公室吸烟。
Don't be standing in the rain . 别站在雨里。
Not to be careless when you're driving a car . 开车时不要粗心大意。
4) 感叹句（Exclamatory Sentence）
感叹句表示说话人的喜悦、气愤、惊讶等强烈的情绪。这类句子中，有很多是由What或How引起的。What 用来强调名词，How则强调形容词、副词或动词。这类句子的构成只需将所强调或是说，所感叹的对象放到句首；句子无需倒装，句子要用正常语序。 当然，如果不用这种句型，而句子（无论是那种句子）本身又表示了上述的种种情绪，那么该句也就成了感叹句。例如：
What a fine day it is today ! 今天天气多好啊！
How fine it is today ! 今天天气多好啊！
What a lovely son you have !你有个多可爱的儿子啊！
How lovely your son is ! 你的儿子多可爱
如果还有什么不明白 请问我 随时恭候 我英语今年高考可考了120多啊

中学英语语法精典总结 1.sometimes/some times/sometime/some time: sometimes: “有时”=at times. He is sometimes late for school. some times: “几次”I have been to Nanjing some times. sometime: “某一时刻”I bought it sometime last spring. some time: “一段时间”We have to stay here for some time. 2.need 的用法：1.need可当情态动词（和can等用法类似，但need只用于疑问句或否定句中）：Need I go now? (need 在一般疑问句的开头) I needn’t tell you the answer. (否定句中直接在need后加not) 【当情态动词时，need无时态变化。】 need 可当行为动词（和want 等用法类似）： He needs a bike. (后可直接加名词) I need to go over my lessons. (后接带to不定式) Do you need to have a rest? （一般疑问句中do, does, did在句首） We don’t need to wait for her coming. (否定句中do,does,did提前) 【注：need 后接表被动的内容时，可表达为： The TV needs to be repaired. = The TV needs repairing.】 3.do with 与deal with: 都译为“处理，对付，安排，应付” What have you done with the milk? 用what提问。 How shall we deal with this problem? 用how提问。 下面两句由此而来：Could you tell me what to do with the milk? Could you tell me how to deal with this problem?4.就近原则：常见的有：Either you or Lucyis wrong. There is a dog and two cats in the yard. (there be句型) Not only you but (also) Iam strict in the work. Neither you nor Lucy has seen the film before. 5.主谓一致：One/Neither of you is right. （单数谓语） Tom, with his friends, has gone. (主语是Tom, 单数谓语) This pair of shoes looks beautiful. （主语是pair, 单数谓语） The shoes look beautiful. （主语无pair, 复数谓语） Every boy and every girl has a chance to do it. （单数谓语） The old need to be looked after carefully. The young are energetic. (the 加形容词表一类人，谓语用复数) Mr. and Mrs Green are from America. 指格林夫妇 (复数谓语) The teacher and writer is an able man.指教师兼作家, 一个人，单数谓语。 Both you and I are excited about the news. （复数谓语） the number of与a number of6.quite/such/really用法之一：如果出现不定冠词时，常放在后面。 It’s quite an easy question. He is quite a clever boy. It’s such an important lesson.(另见33) Lily is really a lazy girl. 7.部分用what 提问的句型： What size do you want? What will you do with the problem? What’s the population of China? What day is it today? What’s the date today? What’s the price of this one? 8.there be部分用法：1There is only a student taking notes now. There is no need to open the box. There are 20 trees to be planted. 2常有以下结构: there may/will/must/is going to/used to/…be. … 3there be中不可再出现have/has/had(有)的词。 9.常见表否定的词或短语:no, not, hardly, few, little, neither, nor, nothing, nobody, none, nowhere等. 有些有时在某些句型中也相当于否定，如without, too…to… without anything, too tired to go any further 但前缀如dis--, un--, in--或后缀如--less,并不表否定。 10.常见后接动词原形的词或短语: why not / had better / please /would you please / let / make / 情态动词，等等。【注意否定形式：had better/ would you please/ let直接加not + 动原；而please加don’t+动原】 11.常见后接动词ing的词或短语：finish /enjoy /practice /give up / end up /put off /consider /keep /feel like /prefer…to…/can’t help / be busy /be worth /take turns /miss(错过) /spend /have fun /介词等。 12.常见后接带to不定式的词或短语：want /hope /wish /allow /encourage /ask /tell /pretend /decide /plan/invite /urge/ advise/warn/ seem /in order (为了) /疑问词，等等。 另外it作形式主语，后也常有带to不定式。 【否定：以上大多词 + not + to do sth】 13.被动语态(be +v.过去分词)用法：I did it. →It was done. 双宾:He told us a story.→We were told a story.→A story was told to us. She passed me a pen.→I was passed a pen.→A pen was passed to me. 情态动词:We can make a plan. →A plan can be made. 进行时态:Tom is writing a letter.→A letter is being written by Tom. 完成时态：I have finished the work. →The work has been finished. 14.名词或所属格作定语：1强调性别时a man doctor / two men doctors ； a woman teacher / six women teachers 被修饰词是单数时，性别也用单数；被修饰词是复数时，性别也用复数。 2a girl actor / four girl actors a boy player / two boy players a bus station / some bus stations 复数只变被修饰的词。 3a boys’ team / a gentlemen’s holiday / the Teachers’ Day / the Children’s Day “复数 + ’s ”作定语，译为“…的…” 4Father’s Day / Mother’s Day 此处“单数 + ’s ”作定语。 附：and连接的名词所属格：Lucy’s and Ann’s fathers are workers. 分别是两个人的爸爸，所以应分别加“’s” Lucy and Ann’s father is very interesting. 两个人共有的爸爸，所以在两人后只加一个“’s”。） 15.win与beat区别：win后加物：I’m sure Jim will win the match. We won the first place in the sports meeting. 而beat后加的是人：I’m afraid they will beat us. I hope we can beat the boys’ team.

(加时间) He put some books at the end of the bed. (加地点) 2by the end of +时间点，“截止到…末” 若接过去的时间点，常用过去完成时：They had planted six thousand trees by the end of last month. 若接将来的时间，常用一般将来时：We shall finish the work by the end of next month. 3in the end “最后”，后不加of 短语：They wanted to find a place to rest in, in the end, they saw a village. 18.have gone to/have been to/have been in: 1have gone to+地点“已去了…（还未回来）”-I can’t find those children, where are they? -They have gone to the farm.

I’ve been here for 2 hours/since 2 hours ago. (此短语省略了in) 19.all/whole用法：all (of) the land / all (of) the class / all (of) the students…【all 在定冠词the 前】 the whole school / the whole country / the whole area…【whole 在定冠词the 后】 20.a bit / a little区别：都可作副词，后直接加形容词和副词。 I’m a bit / a little hungry. She feels a bit / a little tired. 也可作代词或形容词，后接名词时有所不同： I have only a little drink. She ate a little bread and went out. (a little 直接加名词) 而下文：I have only a bit of drink. She ate a bit of bread and went out. (a bit 先加of再加名词) 21.“擅长”与“不擅长”; “对…有利”与“对…有害”： “擅长”：be good at / do well in “不擅长”：be bad in / be poor in / be weak in / do badly in “对…有利”：be good for “对…有害”：be bad for 22. 表数量的词和短语的部分用法：1none / all / some / most / plenty of / a lot of (lots of) 后既可接可数名词复数，也可接不可数名词。2many / (a) few / a number of / several只接可数名词复数。3much / (a) little / a bit of只接不可数名词。 23.易用错的副词：1really可修饰动词、副词和形容词，常在它们前面。I really love reading. I really miss you. (修饰动词) Tom speaks really quickly. 汤姆说得非常快。（修饰副词） It’s really kind of you. 你真好。 (修饰形容词) 2very much常修饰动词want, miss, hate, love, like, dislike, enjoy, take after(长得像…), move(使…感动), excite(使…激动)等等。常在句尾。Jack wants to go there very much. 杰克很想去那 23very修饰形容词和副词，放在它们前面： She is very kind. I am very happy. Peter speaks very slowly. (very不可修饰动词：I very like English. He very misses you.等类似结构都是错误的。) 24.常用于现在完成时的词或短语：for（后加时间段，句中谓语用延续性动词）；since（后加时间点或一般过去时的句子，主句谓语用延续性动词）；How long（对时间段或for与since引导的内容提问，句中谓语也用延续性动词）in/all one’s life（在某人一生）；in/ring the past/last+时间段 (在最近的…时间内) ；so far（到目前为止）；yet（用于句尾，用在疑问句或否定句中）；already (用于句中或句尾，用在肯定的陈述句中) ；ever；never；just；before(单独用在句子末尾，常用此时态。但若时间段加before, 常用过去完成时) 以及recently等. 25.形容词与副词区别：1形容词修饰名词，作定语（划线部分）： She is a kind girl. What bad weather! I bought a new bike. 形容词可在系动词后，作表语(划线部分)： The girl is kind. His face turned red. It tastes sweet. 2副词(划线部分)修饰动词、形容词、副词，也可修饰整个句子。 He ran quickly. Please speak loudly. Tim lives alone. 修饰动词 She is very angry. He felt too tired. I’m so lucky. 修饰形容词 He got up quite early. She did it very well. 修饰副词 Unluckily, I failed the English exam. 修饰整个句子26.everyday与every day: everyday是形容词，后接名词，“日常的”。He is practicing everyday English. every day是副词，作时间状语，“每天”。We speak English every day.
6. 初三英语语法知识
太多了
语法这东西，要长期积累
很固定的搭配啊，句子类型啊，从句类型啊，词性搭配啊。版。。太多太多
我说几权个比较好用的
情态动词（should,can,may等），普通助动词（do,does)后跟动词一定是原形
介词后跟动词一定是ing形式
做题不会的时候这些很好用的
7. 初三英语语法知识点（只问一个很简单的）要快
1.

2.
used
to
do是主动语态，意思是“回过去常常答做某事”，表示现在不这样做了。

8. 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)…

Unit 9 When was it invented ?
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”。
①表示过去某一时间可用by, before 等构成的短语来表示
②也可以用when, before, after 等引导的时间状语从句来表示
③还可以通过宾语从句或通过上下文暗示。
When I got there, you had already eaten you meal.
当我到达那里时，你已经开始吃了。
By the time he got here, the bus had left.
到他到达这里时，汽车已经离开了
典型题例
1、He said he had never seen that film before. Instead,he_____many novels.
A. has read B. had readed C. had wrote D. had read
此题应该选用D项。从“He said he had never seen that film before ”中
可知是过去完成时态，而从“ Instead,”中可以知道与前面的宾语从句是并列的内容，故应该选用“had read”。
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
词连接，而从“when they got to the station. ”中可以知道过去时间点以前的事情，应该用故应该选用“had been away ”。
3、A week later, I received a book that I _____ on line.
A. has ordered B. had ordered C. would order D. was ordering
此题应该选用B项。从“I received a book ”中可知与动词“order ”的
前后关系，应该是在“收到书以前已经预订了”，故应该用“order”的过去完成时态结构表示“过去的过去”这一概念。故应该选用“had ordered”。
4、The boy told his mother that he ____ ill since he came back from the school.
A. has been B. would be C. had been D. was
此题应该选用C项。从“ …since he came back from the school.”中可知前面的主句是完成时态，但是从“The boy told his mother ”结构中可以知道应该用相应的过去时态，，故应该选用“had been”。
5、When we got to the field, the football match ____ already ______.
A. has started B. had started C. will begin D. is going to start
此题应该选用B项。从“already ”中可知是完成时态，但是从“ When we got to the field”结构中可以知道应该用相应的过去时态，故应该选用“had started ”。
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
9. 初三英语，语法知识，
1 选C 这题有for three weeks表一段时间，动词必须是延续性的。而go away是瞬间动词不能与一段专时间连用，所以改成延续属性的be away, be的现在完成时是has been.所以选C
2. A。 只要延续性动词可以与一段时间连用。这题只有be动词表状态，为延续性类，BCD的动词都是短暂性的。
