1. 初三第一学期人教版英语1-7课所有语法重点
1.现在完成时
现在完成时用来表示之前已发生或完成的动作或状 态,其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在;也可表示持续到现在的动作或 状态。其构成: have (has) +过去分词。
2.比较过去时与现在完成时
1)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)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, 具体的时间状语
共同的时间状语:
this morning, tonight,this April, now, once,before, already, recently,lately
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,
不确定的时间状语
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.
过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。
举例:
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,可能为不公平竞争。)
She has returned from Paris.
她已从巴黎回来了。
She returned yesterday.
她是昨天回来了。
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)
He joined the League three years ago.
( 三年前入团,joined为短暂行为。)
I have finished my homework now.
---Will somebody go and get Dr. White?
---He's already been sent for.
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.
3. 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.
4. 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
5.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,应用现在完成时
关于since;
since的用法主要有两点:一是表示“自从……以来”,二是表示“既然”之意。但如果只了解词的含义,而不了解其用法,在使用时就会造成错误。例如:I have not heard from him since I lived in Shanghai.
不少人会望文生义,将该句译为:“自从我住在上海以来,就再也没有收到他的信了。”而实际上这个句子的译文并非如此,那么正确的含义是什么呢?
下面谈谈since作连词引导时间状语从句的用法。
一、若since引导的状语从句的谓语动词是终止性的过去时,则从句表示的时间是“从动作开始的那一时刻起”。如:
He has studied very hard since he came to our school.自从他来到我们学校,他学习就非常努力。
We have been missing them since they left here自从他们离开这里,我们就一直很想念他们。
这是最常见的一种用法,此处不再多述。
二、若since引导的状语从句的谓语动词是持续性动词或表示状态的动词的过去时时,则从句表示的时间是“从那持续动作或状态结束时算起”。如:
I haven’t heard any noise since I slept. Sleep 为持续性动词,sleep的动作结束时,即“醒来”时,这句应译为“我醒后还未听到任何声音”。
John is now with his parents in New York, it is already three years since he was a teacher约翰现在和父母一起住在纽约,他不当教师已经三年了。
本文开始出现的那个句子就可以译为“自从我离开上海,就再也没有收到他的信。”这种译法常被人们误用,我们不妨再多举几个例子看看:
How long is it since you lived in Shanghai?你离开(没住在)上海多久了?
It is half a month since he was a League member.他退团(不当团员)半个月了。
It’s been quite some time since I was last in London我离开伦敦已很长时间了。
比较:He has written to me frequently since I was ill.自从我病愈以来,他屡次给我写信。(从句谓语为状态动词)
He has written to me frequently since I fell ill.自从我生病以来,他就屡次给我写信。(从句谓语为终止性动词)
三、若since引导的状语从句的谓语为持续性动词的现在完成时,则表示动作和状态延续到现在(说话时刻),其表示的时间的起点应从动作发生之时算起。如:
I haven’t heard from him since he has lived there。
这里has lived表示动作的持续性,时间的起点应从:“开始居住”时算起。因此此句可理解为“自从他(开始)住在那儿起,我就一直没收到他的来信”。
Since we have owned a car, we have gone camping every year。自从我们自己有了汽车,我们每年都去野营。
试比较:1. Since I’ve been at this school, we have had three headmasters.自从我到这所学校,我们已换了三个校长了。
Since I was at this school, they have had three headmasters.自从我离开这所学校,他们已换了三个校长了。
2.He has never been to see me since I have been ill. 自从我生病以来,他从未来看过我。
He has never been to see me since I was ill. 自从我病愈以来,他从未来看过我。
由此可见,since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反。换言之,前者以肯定的语法形式反映着否定的逻辑内容,而后者的形式与内容是一致的。
至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法,后者是口语说法。
应注意的是,在这种结构中,since引导的从句绝对不能用否定式的谓语动词来表示否定意义,下面两句都错了:
It is a long time since he didn’t study English.
It’s two months since you didn’t come to see me.
正确的说法为:
It’s a long time since he studied English 他好久没学英语了。
You haven’t come to see me for two months. 你有两个月没来看我了。
解析:6B 词义辨析语句连贯尽(as long as)作者所能记忆的。Remember是持续性动词,与表示持续意义的as long as(象……一样长;只要……)连用,引导条件状语从句。as soon as,when,since三项均表示短暂意义,通常与短暂性动词连用
2. 初三上学期英语重要的词组,语法
1.时态复习(一般现在时,一般过去时,现在进行时,过去进行时,一般将来 时,现在完成时)
一般现在时:I /You/get up at 6:00 every day
一般过去时:he was tired after working
现在进行时:He is playing soccer on the playground
过去进行时:I was playing football when they came to my school
一般将来时::He will join our party.
现在完成时:We'll start at once if the rain has stopped
2.被动语态(一般现在时态的被动语态,一般过去时态的被动语态,一般将来时态的被动语态,现在完成时态的被动语态,情态动词的被动语态)
一般现在时态的被动语态:am/is/are+done

4.前后缀构词法(re-, in(m)-, un-, dis-, anti-, -able, -ful, -less)
1.-able 以“-able”结尾的形容词一般有两种情况:
(1)v.+able→adj. 以这种方式构成的形容词其意义为“能……的”、“可以(被)……的”、“适 合于……的”、“值得……的”等,即有被动含义。例如:reliable(可以依靠的),drinkable(可以饮用的 ),eatable(可食用的)。
(2)n.+able→adj. 这种形容词意为“具有……特点的”,如valuable(有价值的),reasonable( 有道理的),comfortable(舒适的)。
2.-ible 该词缀在意义上与“-able”相同,但主要用于拉丁语后。例如:terrible,horrible,invi sible,possible。
3.-al 该词缀大多是加在名词后形成形容词的。不过,有些“-al”后缀则仅体现了该词的形容词性 ,并非以这种方式构成形容词。“-al”意为“属于……的”、“有……特性的”。这类词在中学英语中颇多 ,如actual,general,international,medical,mental,moral,natural,official,several,special,usual。( 这类形容词大部分没有比较级和最高级)
4.-an “-an”加在国名、地名之后,表明是相应的形容词,如American,African。
5.-ian “-ian”与“-an”相同。例如:Asian,Australian,Canadian,Indian,Italian。
6.-ant “-ant”表示“……性的”。带“-ant”后缀的形容词其相应名词往往是-ance或-ancy后 缀。例如:instant(instance),distant(distance),important(importance),brilliant(brilliancy),consta nt(constancy),pleasant。
7.-ent “-ent”与“-ant”非常相似。例如:absent(absence),different(difference),excelle nt(excellence),patient(patience),present(presence).
8.-ar “-ar”意为“……的”、“……性的”,如popular,particular,regular。
9.-ary “-ary”意为“……的”、“与……有关的”。例如:contrary,necessary,ordinary,prim ary,revolutionary。
10.-ed “-ed”加在动词之后形成形容词。实际上该形容词是由原动词的过去分词演变而来的,因 此它有被动含义。这种形容词在中学英语中出现很多,有connected,discouraged,disappointed,engaged,exc ited,interested,limited,married,pleased,tired,united,used(习惯的),worried,wounded。
“-ed”也可加在动词之后形成复合形容词,如man-made,water-covered。
“-ed”还可加在名词之后形成复合形容词,如warm-hearted,warm-blooded,three-legged。
11.-en “-en”有两种情况:
(1)“-en”跟在一些物质名词之后构成形容词,表示“材料”或“质地”,如wooden,golden,earthe n。
(2)“-en”也可加在一些不规则动词之后形成形容词。这些形容词实际上是由过去分词转换而来的。 例如:spoken,written,stricken,mistaken。
12.-ern “-ern”加在表示方位的名词之后,表示“……(方位)的”。这样的词有eastern,sout hern,western,northern等。
13.-ese “-ese”加在国名、地名之后构成相应形容词。例如:Chinese,Japanese.
14.-ful 这一后缀有两种情况:
(1)加在名词之后构成形容词,表示“充满……的”、“有……性质的”,如beautiful,colourful,he lpful,powerful,successful,useful,wonderful。
(2)加在动词之后,所构成的形容词意为“易于……的”,如forgetful。
15.-ic “-ic”常常加在名词或依附于词干后,构成形容词,意为“……的”、“……似的”、“ 与……有关的”等。例如:Atlantic,electric,arctic,historic,pacific,plastic,public,scientific。
16.-ical “-ical”同“ic”一样附加在名词或词干后构成形容词,意为“……的”、“……似的 ”、“与……有关的”,如physical,political,practical,technical等。
注:(1)有些形容词的词尾可能是“-ic”和“-ical”并存,且可以互相替代,但这不是说两者就没 有任何区别。一般来说,词尾“ic”与词根的关系比较密切,而词尾“ical”与词根的关系比较含糊,一般作 “与……有关的”解。请比较:an electric light(电灯),electrical engineering(电气工程);histo ric意为“历史上有名气的”,historical则意为“关于历史的”。(2)以“ic”结尾的形容词,其相应副词 则往往是pacifically,scientifically。
17.-ing 词尾“-ing”也可构成形容词,但这种形容词实际上是现在分词形容词化了,因此,此类 形容词表示主动。例如:dying,exciting,inspiring,interesting,freezing,living。
另外,“-ing”词尾还可构成合成形容词,如good-looking,ordinary-l
18.-ish “-ish”意义较多,在中学英语中,其主要意义是“……民族的”、“……语的”、“… …似的”、“患……的”,如English,British,foolish,feverish。
19.-ist “-ist”表示“……主义的”、“信仰……的”。该后缀加在名词之后,如communist,im perialist,Marxist,socialist。
20.-ive “-ive”意为“……的”、“与……有关的”、“具有……性质的”等。例如:native,a ctive,passive,attentive,expensive。
21.-less “-less”加在名词、动词后,表示“无”、“缺”,如fearless,harmless,useless,he lpless,careless。
22.-ly “-ly”加在名词之后构成形容词。这一词缀的意义有二:
(1)“像……的”、“有……性质的”,如friendly,lively,lovely,lonely,orderly。
(2)“以……为周期的”、“每……的”,如hourly,daily,weekly,monthly,yearly。
注:如是形容词之后加“-ly”,则构成副词。上述(2)中的形容词亦可用作副词。
23.-(i)ous 该形容词后缀意为“充满……的”、“具有……特征的”,加在名词、动词和形容词 之后。例如:curious,famous,dangerous,obvious,poisonous,serious,various。
24.-some “-some”加在名词、动词之后,表示“使人……的”、“易于……的”,如handsome,t roublesome,tiresome。
25.-ward 它加在名词之后,表示方向,作“向……(方向)的”、“来自……(方向)的”解。例 如:eastward,southward,westward,northward,forward,backward,inward,outward,upward,downward。
注:这些词也可以是副词。如果词尾是“-wards”时,派生词必然是副词。
26.-y “-y”加在名词之后,表示“具有……特征的”、“多……的”。例如:funny,lucky,shab by,snowy,thirsty,windy,sunny,rainy,cloudy,dirty,sty。
以上是中学英语中出现的主要形容词词缀。还需说明的一点是,大部分形容词是从完整的单词上加后缀派 生来的,而有些则是在拉丁词或希腊词的词根上派生来的5.定语从句(that,which,who,whose引导的定语从句,引导词的省略)
6.冠词与数字
定冠词和不定冠词和不用冠词
1.不定冠词的基本用法
(1不定冠词有a和an两种:a用于辅音音素开头的词前,an用于元音音素开头的词前。例如:a boy, a city, a girl, a useful animal , an old man, an honest boy, a bad apple, a tall elephant
(2用来表示“—”的意思,但不强调数的观念,只说明名词为不特定者。即不具体说明是何人何物。例如:A teacher is looking for you.We work five days a week.
(3)不定冠词含有“—”的意思,但数量观念没有one强烈,在句子里边一般可以不必译出,但若有“一个”的意思则译出,例如:
—— An orange is good for you. 桔子对你有好处。
—— How much is it ? 多少钱?
——Two yuan a kilo. 二元一公斤。
(4)一般用在可数名词单数前,指人或事物的某一种类。例如:Bill is a student.
Pass me an apple, please.
例外:I have never seen such a fine film.
(5)用在某些固定词组中。例如:a lot of, a moment ago, a few, a little
2. 定冠词的用法
(1)特指某(些)人或某(些)事物。 例如:The book on the desk is mine.
Show me the photo of the boy, please.
(2)指双方都知道的人或事物。 例如:Open the door, please. 请开门。
Did you see the boy? 你看见那个男孩了吗?
What’s the new teacher’s name? 新老师的名字叫什么?
(3)指上文提到的人或事物。例如:He lives on a farm. The farm is not big.
他住在农场,这农场不大。
There are some dogs. The dogs are very lovely.
这儿有一些狗。这些狗很可爱。
(4)用在世界上独一无二的事物前。例如:The sun is bigger than the moon.太阳比月亮大些。
但这些名词作为描绘性定语时,可用不定冠词。例如:Look! A red sun is rising. 瞧!一轮红日正在升起。
(5)用在序数词和形容词最高级前。例如:The first island is the biggest of the three.第一个小岛是三个中最大的。
(6)用在用普通名词构成的党派,国家等专有名词以及江河、海洋、山脉、群岛、海峡、海湾等专有名词前。例如:They will visit the Great Wall next week.
They came to the United States of America last year.
The Communist Party of China was founded on July 1st, 1921.
The Yellow River is the second longest river in China.
(7)用在形容词前表示一类人,the +形容词指的是一群人,是一种复数含义,所以其后动词应用复数形式。例如:The old are sick.
(8)用在姓名复数形式前表示一家人。例如:The Smiths have moved to London.
(9)用在某些习惯用语中。例如: in the morning, on the left, the day before yesterday, all the same
三、不用冠词的情况
(1)星期、月份、季节、节日前一般不用冠词。但是中国传统节日前习惯用冠词。例如:
All of us like the spring festival. 我们喜欢春节。
It’s Sunday today. 今天是星期天。
He was born on June 12, 1999. 他出生于1999年6月12日。
Today is Father’s Day. 今天是父亲节。
If winter comes, can spring be far behind? 冬天来了,春天还会远吗?
但是如果被一个限制性定语修饰或有表示继续的介词ring, through时与表示一段特定的时间,则在季节前要加定冠词。例如:She came to Shanghai in the spring of 1987.她是一九八七年春天来上海的。
The school was completed in the September of 2000.这学校是2000年9月落成的。
He swims every day ring the summer. 他夏天的每一天都游泳。
虽不特指某一年的季节,但说话人把某季节看作一年的一部分,即一年的某一段时间。则在季节前要加定冠词。例如:We play football in the winter.
(2)在称呼语或表示头衔的名词前。例如:Mr. Li is our headmaster. 李先生是我们的校长。
After lunch Aunt Huang came in. 午饭后黄阿姨来了。
(3)各词复数表示一类人或事物时。但若各词复数被一个限制性定语修饰,则要加定冠词the. 例如:I like cakes very much. 我非常喜欢蛋糕。
My father and mother are the doctors in People’s Hospital of Shanghai.
(4)在三餐饭,球类运动与棋类游戏,学科名称的名词前。但若表示某一种或某一个特定的概念时用冠词。例如:He had supper with us yesterday. It’s a very good supper. 他昨天和我们吃晚饭,这是一顿丰盛的晚餐。
My brother likes to play football. 我兄弟喜欢踢足球。
Let’s go and watch them play chess. 让我们去看他们下棋。
(5)在物质名词,抽象名词,人名,地名等专有名词和不可数名词前. 但若不可数各词有其它限制词修饰时,则要加定冠词the. 例如: Smith is our teacher. 史密思是我们的老师。
Milk is good for us. 牛奶对我们有好处。
The water in the pool is very dirty. 坑里的水很脏。
(6)名词前已有作定语的this、that、my、your、some、any、等限定词时。例如: Come this way, please.
I’ve some question to ask you.
My brother is a student.
7.主谓一致
重点是定语从句,被动语态

7. 九年级上学期英语1-6单元重要词组,句型,语法重点和用法!!
你花了我一个晚上的时间!希望能帮到你!
一、知识点
①英语有两种语态:主动语态和补动语态
主动语态表示是动作的执行者
被动语态表示主语是动作的承受者
Cats eat fish. (主动语态)猫吃鱼。
Fish is eaten by cats. (被动语态)鱼被猫吃。
②被动语态的构成
由“助动词be +及物动词的过去分词”构成
助动词be 有人称、数和时态的变化,其变化规则与be 作为连系动词时完全一样。
时态 被动语态结构 例句
一般现在 时 am
are +过去分词
is English is spoken in many countries.
一般过去 时 was +过去分词
were + 过去分词 This bridge was built in 1989.
情 态
动 词 can/should
may +be+过去分词
must/…… The work must be done right now.
③被动语态的用法
当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者,或者只需强调动作的承受者时,要用被动语态。
2. allow sb. to do sth. 允许某人做某事(主动语态)如:
Mother allows me to watch TV every night. 妈妈允许我每晚看电视。

She went to school just now. So did I . 她刚才去学校了,我也是
