④ 8年级的英语语法概念
Ⅰ. 初中英语八种时态归纳复习
时态是英语学习中一个至关重要的内容,广大初中学生在实际运用时,往往对时态总是倍感棘手,下面我们就归纳复习一下这几种时态。
一、一般现在时:
概念:经常、反复发生的动作或行为及现在的某种状况。
时间状语:
always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, etc.
基本结构:①be动词;②行为动词
否定形式:①am/is/are+not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
二、一般过去时:
概念:过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为。
时间状语:ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc.

否定形式:①was/were+not;②在行为动词前加didn't,同时还原行为动词。
一般疑问句:①was或were放于句首;②用助动词do的过去式did 提问,同时还原行为动词。
三、现在进行时:
概念:表示现阶段或说话时正在进行的动作及行为。
时间状语:now, at this time, these days, etc.
基本结构:am/is/are+doing
否定形式:am/is/are+not+doing.
一般疑问句:把be动词放于句首。
四、过去进行时:
概念:表示过去某段时间或某一时刻正在发生或进行的行为或动作。
时间状语:at this time yesterday, at that time或以when引导的谓语动词是一般过去时的时间状语等。
基本结构:was/were+doing
否定形式:was/were + not + doing.
一般疑问句:把was或were放于句首。

一般疑问句:have或has。
六、过去完成时:
概念:以过去某个时间为标准,在此以前发生的动作或行为,或在过去某动作之前完成的行为,即“过去的过去”。
时间状语:before, by the end of last year(term, month…),etc.

Ⅱ. 几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
一、一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作), at school(上学、上课)等。此短语可与进行时态转换。请看:
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming, Mum! 意为“我就来,妈妈!”请看:
The train is leaving soon.
The train will leave soon.
四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换
“be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。请看:
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday

八、宾语从句的时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.

你认为今年公众会选谁为他们最喜欢的歌手.
[编辑本段]宾语从句(版本二)
学习宾语从句要抓住三要素:连接词、语序和时态。
1.连接词
连接词一般都是that(指事务或人),which(指事),who(指人)
1.从句为陈述句,常选择连接词that或将that省略,直接与主句相连。
2.从句为一般疑问句,常选择连接词if或whether。在 whether … or not 结构中不能用 if 替换。
3.从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代、副词作连接词。
注意:当who为主语时,句式为:who+谓语+其他
2.判断时态情况:
1.主句是一般现在时,从句为各种时态情况。
2.主句是一般过去时,从句为各种相应过去时态注意:从句描绘客观事实,用一般现在时。
eg:
1. The teacher told the children that the sun____ round.
A. was B. is C. were D. are
2. I believe that our team____ the basketball match.
A. win B. won C. will win D. wins
3. I don’t know____ to visit the old man.
A. whether B. if C. that D. who
4.The soldiers soon reached( )was once an old temple( )the villagers used as a school.
A.which;where B.what;which C.where;which D.what;where
答:选B,动词reach后接宾语从句,从句缺少宾语,where不可,which引导宾语从句时表疑问含义“哪一个…”而此句中并非疑问含义,不知道哪一座庙宇,而是用what从句表陈述含义,意“过去的一座旧庙宇”;temple后为对其修饰的定语从句,用关系代词which代替,并在从句中作动词used的宾语,use sth. as…“把…用作…
[编辑本段]宾语从句(版本三)
宾语从句,在复合句中作宾语,位于及物动词后。
eg.
Tell him which class you are in .
Do you know what he likes?
注:
(1)主、从句时态一致:
主句谓语过去时,从句相应过去时;
He answered that he was listening to me.
主句谓语现在时,从句时态任所需;
eg. He says (that) he will leave a message on my desk.
They know (that) he is working hard.
具体过去永不变,真理格言现在时;
eg.He told me that he was born in 1980.
Father told me that practice makes perfect .
(2)否定前移,及完成反意问句
在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时,应转移到主句上去,完成反意问句时,应与从句主、谓保持一致。(注: 否定前移的条件是,主句主语是第一人称)
eg. I don't think you are right ,are you ?
I don't believe they have finished their work yet,have they ?
(3)运用虚拟语气的情况
在表示:
建议 suggest , advise
要求demand 、desire、require、request、propose;
决定 decide;
命令 order、command;
坚决主张 insist;
等动词后跟宾语从句,用(should)+v.(虚拟语气)
eg. I suggested that you(should)study hard.
He ordered that we should go out at once.
(4)宾语从句后置情况
如果宾语从句后有宾语补语,用it作形式宾语,把宾语从句后置
eg.You may think it strange that he would live there.
(5)宾从中that不可省略的情况
宾语从句that常可省略,但在以下情况下不能省略
A.当主句谓语动词带有两个或两个以上宾语从句时,可以省略第一个that,其他不能省略。
eg.I believe(that)you have done your best and that things will get better.
B.当it作形式宾语时
eg.She made it clear that she had nothing to do with him.
C.当宾语从句前置时
eg.That our team will win,I believe.
[编辑本段]宾语从句(版本四)
一、定义和宾从例句分析
宾语从句就是一个句子作动词或介词的宾语。
A 作动词的宾语:
I heard the news.
主语 谓语动词 名词作宾语
I heard that he would come here later on.
主语 谓语动词 一个句子作宾语---宾语从句
B 作介词的宾语:
He said nothing about the plan.
主语 谓语动词 代词作动词的宾语 介词 名词作介词的宾语
He said nothing about who broke the window last night.
主语 谓语动词 代词作动词的宾语 介词 一个句子作介词的宾语
二、带有宾语从句的复合句的构成
带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。连接词有:that(可省略),what, who, when, where, why, which, if, whether, how.
1 He suggested (that) we should clean the corridor every day.
宾语
2 He told me (that) he would leave Dalian airport at 8pm.
间接宾语 直接宾语
3 He told me where he was going to travel that summer.
间接宾语 直接宾语
4 He wanted to know what the manager had said at the meeting.
who hadn’t passed the exam.
when she would leave this building.
why she cried last night.
where she was going to study.
which student was his partner in the short play.
if (whether) Tom could play basketball with him that morning.
how she managed to solve the problem.
why water flows from a high position to a lower position.
在例子4中,当主句是过去时态时(一般过去时,过去进行时,过去将来时,过去完成时),从句根据不同情况必须使用过去时态的一种,(大自然的现象和真理除外)。
5 He is wanting to know what I can cook for dinner.
who broke the window yesterday.
when I can have a holiday.
why I failed the exam yesterday.
where I should have dinner with my friend tonight.
which book is the best one.
if (whether) I have passed the exam.
how my cat escaped from the room last night.
在例子5中,当主语是现在时态时(一般现在时,现在进行时,一般将来时,现在完成时),从句可根据不同情况使用各种时态。
三、注意
A 宾语从句必须用陈述语序。
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
B 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
Bad: He left whether we should continue this project to my judgment.
Good: He left it to my judgment whether we should continue this project.
C 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.
Good: I don’t think he likes the English teacher.
D 主句一般过去时态,从句也要用过去时态;具体细节请看第一部分。
False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner.

⑥ 新人教版 新目标 八年级 下 英语 需要掌握的动词词组 句型 语法
用言就是拿来用的语言。用言包括动词、形容词、形容动词。
体言就是一些名词性的东西,顾名思义就是有实体的语言(我自己捉摸的,当时我也从标日的说法到这些折腾了很久)包括名词、数词、代词。
用言连体形就是用言后边接体言的时候要变的形态,动词连体形就是动词要接体言的时候要变的状态……字面上直接看就可以懂了。
终止行就是这个动作(形容词)的中止时候的状态,原型和简体过去型都是。
连用型就是连接用言的形态(啊!我要疯掉了)
在新的分类里(之前是1段,5段这样的来的)是按照数量的多少分类的。
1类动词就是最最多的动词,之前的5段动词,2类就是1段动词。3类动词就是サ变动词,カ变动词叫做特殊类动词
形容词也一样,1类是形容词,2类是形容动词
例子的话……自己搞吧……你说的这些都详细的举例子的话不就是一本语法书么……基本的明白了的话,就不用举例子了,现实的例子太多
以上……哭泣ing
用言就是动词,形容词,形容动词。
体言就是名词,代词,数词。
用言连体形就是用言连接体言是的变形。例如:大きい+鸟=大きい鸟。
动词连体形就是用言连体形的一种。例如:违う+ところ=违ったところ
用言终止形就是原形或者た形。
连用形就是连接用言的变形。例如:美味しい+なる=美味しくなる
一段动词一样的,两段动词就是五段动词。
一类形容词就是形容词,二类就是形容动词。
这些我给你分开了!
并且改了一下!
希望能帮上你的忙!!!!
这里哦可能有!!!!
⑦ 初二英语下册重点语法、句型归纳总结
下册主要就是被动语态啦被动语态的主要用法
一.定义
语态是动词的一种形式,它表示主语和谓语的关系。语态有两种:主动语态和被动语态。如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态;如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态。
■当不知道或没有必要指出动作的执行者时,常用被动语态,这时往往不用by短语。
The front window in the classroom was broken yesterday. 昨天,教室的前窗被打破了。(不知谁打破的)
They have been poorly paid. 他们的工资太低。(没必要指出工资是谁付的)
■突出或强调动作的承受者,如果需要说出动作的执行者,用by短语。
The time-table has been changed. 时间表已变动了。(要突出的是“时间”)
These books are written especially for children. 这些书是专门为孩子们写的。(强调的是“”这些书)
■为了使语言得体或圆滑等不愿意说出动作的执行者。如:
You are requested to make a speech at next meeting. 请您在下次会议上作个发言。
It is said that she is going to be married to a foreigner. 据说她要嫁给一个外国人。
■出于修辞的原因,或是说为了更好地安排句子。如:
The notion is especially opposed to by those who have invested much in the area. 这个提议特别遭到了那些在本地区投资很大的人的反对。(因those的定语太长了,若用它作主语,主语与谓语就相距太远而显得句子松散。)
8种常用时态的被动语态
由“助动词be + 动词的过去分词”构成。助动词be 有时态、人称和数的变化。
(1) 一般现在时:am/is/are +过去分词。如:
Rice is grown in south China. 华南种植水稻。
(2) 一般过去时:was/were+过去分词。如:
The glass was broken yesterday. 这块玻璃是昨天打烂的。
(3) 现在进行时:am/is/are being +过去分词。如:
The project is being carried out. 这个计划正在执行中。
(4) 过去进行时:was/were/being +过去分词。如:
This road was being built this time last year. 这条路去年这个时候还在修建。
(5) 一般将来时:will be +过去分词。如:
The cars will be sent abroad by sea. 这些汽车将由水路运往国外。
(6) 过去将来时:would be +过去分词。如:
The manager said the project would be completed by the end of the year. 经理说这个工程在年底前将会完成。
(7) 现在完成时:have/has been +过去分词。如:
This novel has been translated into several languages. 这本小说已被译成了几种语言。
(8) 过去完在时:had been +过去分词。如:
When I got to the theatre, I found the tickets had already been sold out. 我到达剧院时,发现票已卖完了。
使用被动语态“六注意”
一要注意被动语态的不同时态
被动语态由“be+过去分词”,其中的助动词 be 根据情况可使用各种不同时态。如:
She is respected by everyone. 她受到大家的尊重。(一般现在时)
The book will be reprinted soon. 这本书很快会重印。(一般将来时)
The road is being repaired. 路正在修整。(现在进行时)
They have been given a warning. 他们受到警告。(现在完成时)
二要注意带情态动词的被动语态
该结构的基本形式为“情态动词+be(或be的适当形式)+过去分词”。这类结构非常有可能作为语境题出现在考卷中。如:
The rules must be obeyed. 这些规章制度必须遵守。
They shouldn’t have been told about it. 这事是不应当告诉他们的。
三要注意非谓语动词的被动语态
1. 不定式一般式的被动语态。由“to be+过去分词”构成。如:
She asked to be given some work to do. 她要求给她一些工作做。
2. 不定式完成式的被动语态。由“to have been+过去分词”构成。如:
I should like to have been told the result earlier. 我本想让人把结果早点告诉我的。
3. 现在分词一般式的被动语态。由“being+过去分词”构成。如:
I saw him being taken away. 我看见有人把他带走了。
4. 现在分词完成式的被动语态。由“having been+过去分词”构成。如:
Having been invited to speak, I’ll start making preparations tomorrow. 因为邀请我去讲话,我明天就得做准备。
5. 动名词一般式的被动语态。由“being+过去分词”构成。如:
He hates being made a fool of. 他讨厌被别人愚弄。
6. 动名词完成式的被动语态。由“having been+过去分词”构成。如:
Jenny’s not having been trained as a dancer is her one regret. 杰妮没受过舞蹈的专业训练是她感到遗憾的事。
After having been instructed to drive out of town, I began to acquire confidence. 在接到把车开出城的指令后,我开始信心十足了。
注:过去分词没有被动式,因为它本身可以表示被动意义。如:
The door remained locked. 门仍然锁着。
四要注意“get+过去分词”构成的被动语态
英语被动语态通常由“助动词be+过去分词”构成,有时也可用“get+过去分词”构成。如:
James got beaten last night. 詹姆斯昨晚被打了。
但总的说来,用get构成的被动语态不如用be构成的被动语态常见,尤其是在含有施动者的by短语时,用get构成被动语态更是少见。不过有时用be+过去分词构成被动语态构成误解时,人们可能会选get+过去分词来避免这种误解:
The window was broken. 窗户破了(表状态)。/ 窗户被打破了(表动作)
The window got broken. 窗户被打破了(表动作)
五要注意哪些动词不用于被动语态
1. 不及物动词没有被动语态。因为不及物动词没有宾语,所以若将其用于被动语态则没有主语,故不能用于被动语态。但是值得注意的是,有些英语中的不及物动词,译成汉语时却可能是“及物”的,很容易出错,这类动词如:take place(发生),happen(发生),come about(发生),break out(爆发),appear(出现),disappear(消失),last(持续),arise(出现,发生)等:
Influenza usually breaks out in winter. 流感通常发生在冬季。
2. 英语中的静态动词(如have, lack, fit, hold, suit, resemble 等)通常不用于被动语态:
The young man lacks experience. 这个年轻人缺乏经验。
英语不用被动语态几种的情形
1.谓语为连系动词时,不用被动语态。如:He looked fine. 他气色好。The food tastes delicious. 这食物味道很好。
2. 谓语为不及物动词(短语)时,不用被动语态。如:The war broke out in the end. 战争终于爆发了。
3. 宾语为不定式、动词的-ing 形式或从句,表示主语的一些想法、爱好或愿望时,一般不用被动语态。如:
He decided to go with us. 他决定跟我们一起去。4. 宾语是相互代词、反身代词、同源宾语等时,一般不用被动语态。如:
We should help each other. 我们应该相互帮助。He thinks of himself too much. 他对自己想得太多。
5. 宾语是处所、地点时,一般不用被动语态。如:
We will reach the station in two hours. 我们再过两个小时就会到站了。
6. 谓语部分(动词与宾语) 是一个不可分割的动词短语时,一般不用被动语态。如:
The ship set sail this morning. 这艘轮船今天早晨起航了。
通常不用于被动语态的静态动词
那里的人缺乏食物。正:People there lack food. 误:Food is lacked by people there.
从形式上看,第2句是第1句的相应的被动形式,既然第1句为正句,那么第2句从理论上说应该是成立的。而事实上第2句却是个错句。
在英语中,并不是所有的及物动词都可以用于被动语态的,有些动词(尤其是那些静态动词)尽管它们可以带宾语,但却不用于被动语态,这种动词考生容易弄错,其中主要的有:have,lack,fit,suit,cost,let,like等:
他有一台电脑。正:He has a computer.误:A computer is had by him.
他当时正在洗澡。正:He was taking a bath. 误:A bath was being had by him.
我的鞋不适合。正:My shoes don’t fit me. 误:I am not fitted by my shoes.
这架钢琴花了她6000美元。正:The piano cost her 6000 dollars.
六要注意两类被动句型的相互转换
英语中有一种主动句可以转换成两种被动句型,它们通常是一些表示客观说明的句子。如:
People believed that she is honest. 大家相信她是诚实的。
It’s believed that she is honest. 大家相信她是诚实的。
She is believed to be honest. 大家相信她是诚实的。
比较上面两类被动句型可以发现,一类是“it+be+过去分词+that从句”,另一类则是“主语+be+过去分词+不定式”(其中的“主语”为前一类句型中that从句中的主语),通常可用于这两类被动句型的动词有assume, believe, expect, fear, feel, know, presume, report, say, suppose, think, understand等,比较(同时注意其中时态和动词形式的变化):
It’s known that he was a good singer. / He is known to have been a good singer. 大家知道他曾是位优秀的歌手。
表示“据说”的三类被动句型
⑧ 八下英语语法总结简单易懂
八下英语语法
Unit 1
一般将来时
1.定义:表示将来某个时间将要发生的动作或存在的状态
2.肯定句式:主语+will/ shall/ be going to +动词原形
否定句式:主语+will/ shall +not或be not going to +动词原形
疑问句:Will/ Shall +主语+动词原形+其他?
Be +主语+going to +动词原形
3.标志词(时间状语)
tomorrow, in 2012, in +一段时间 (in three days, in five years), next month (week, year), later on, tomorrow morning 等。
*4.现在进行时表将来
come, go, fly, leave, arrive等短暂性动词用进行时表将来.
eg: We are leaving for Hong Kong next week.
Unit 2
情态动词
1. 用法:情态动词表示建议、要求、可能和意愿等。情态动词后面跟动词原形,情态动词没有人称和数的变化。常用的情态动词有:can, could, may, might, must, shall, should, will, would, need等。
2. should的用法
a. should作为助动词shall的过去式,可以在间接引语中与第一人称主语搭配,表示过去将来时间。
b. should作为情态动词,通常用来表示现在或将来的责任或义务,意为“应该”、“应当”,这时它可以和ought to, be supposed to互换使用,可用于各种时态。
3. 情态动词could表示“建议”时不是can的过去式,而表示比can更加委婉的建议。
4. 情态动词can, could, shall, should还可以表示“请求,许可”。shall 和should用于第一人称,表示征求对方的建议或意见。
Unit 3
过去进行时
1. (1)定义:表示过去某一时刻或某一段时间正在发生或进行的动作,常与表示过去某一时刻的时间状语连用。
(2)结构:was/ were +doing
(3)标志词:at this time yesterday, at 8 yesterday morning,有时与when或while引导的时间状语从句连用等。
(4)过去进行时态与一般过去时态的区别:
a. 一般过去时态表示过去发生的动作或存在的状态。
b. 过去进行时态强调过去某一时间正在进行的动作。
2. when 和 while的用法
(1)when一般指时间点,从句中的谓语动词用终止性动词,但也可以跟时间段,这时从句中的谓语动词要用延续性动词。
eg:When I arrived there, it was raining.
(2 ) while意为“正在……时”,表示在某一段时间内某动作或状态是延续的,后面只能跟时间段,而不能用时间点,所以while引导的从句中的谓语动词用延续性动词。
eg:The dog ran out while we were talking.
(3 ) when引导的从句的动作和主句的动作既可以同时发生,也可以先后发生;而while强调主句和从句的动作同时发生。
Unit 4
直接引语、间接引语
1. 步骤:(1)不要“,”“:”“ “ ” ”
(2)要考虑到人称的变化
(3)要考虑时态的变化
(4)要考虑时间状语、地点状语、指示代词的变化
(5)直接引语变为间接引语后,都要使用陈述句语序
2. 直接引语变成间接引语时,要把原来的时态向前推移,几个主要时态的变化规律有:
直接引语
间接引语
一般现在时
一般过去时(客观真理除外)
一般将来时
过去将来时
现在进行时
过去进行时
3. 直接引语变为间接引语后,所用的连接词是不同的
(1)陈述句用that连接,that可省略
(2)一般疑问句用if 或whether引导
(3)特殊疑问句用特殊疑问词引导
Unit 5
条件状语从句
1. 表示“如果……”“在某种条件下,会……”
2. 时态
一般主句用将来时,从句用一般现在时。
主句用过去将来时,从句用一般过去时。
*3. if 与whether 引导条件状语从句时,一般可互换,但也有区别:
(1)引导主语从句,而且放于句首时,必须用whether
(2)引导表语从句时,必须用whether
(3)whether与or not 连用
(4)动词不定式之前必须用whether
(5)介词之后必须用whether
Unit 6
现在完成进行时
1. 定义:表示从过去某一时间开始,一直延续到现在的动作。这个动作可能刚刚开始,也可能仍在继续,并可能延续到将来。
2. 结构:have/ has been +现在分词
3. 标志词:for two weeks, since 2000, all this morning, these few years 等。
*4. since 与 for 用于现在完成进行时的区别:
since用来说明动作的起始时间,所以后跟表示某一时间点的名词性短语
for用来说明动作延续时间,所以后跟表示一段时间的名词性短语
5. 现在完成时与现在完成进行时的区别
a. 现在完成时强调动作的完成情况
b. 现在完成进行时侧重强调动作的持续性
Unit 8
感叹句
what引导名词,how引导形容词或副词。
句式:What + a/an +形容词+可数名词单数+主语+谓语 !
What + 形容词 + 可数名词复数/ 不可数名词 +主语 +谓语 !
How + 形容词/ 副词 +主语 +谓语!
Unit 9
现在完成时
1. 用法:(1) 在未指明具体时间的情况下,现在完成时动词通常可以表示在说话之前已经完成,而后果或影响至今仍存在的动作。
(2) 开始于过去持续到现在(也许还会继续进行下去)的动作或状态。
2. 肯定句式:主语 +have/ has +done
否定句式:主语 + have/has +not+ done
疑问句:Have/ Has +主语 +done ?
3. 标志词:already, never, ever, just, before, yet
*4. come, go, leave, arrive, buy, lose, receive, join, die, bury, marry等动词所表示的动作是一时的,不能延续的,所以不能与表示一段时间的状语连用。但是这些词用于否定句则可与表示持续的时间状语连用,即动作的不发生是可以持续的。
Unit 10
1.祈使句。祈使句后一般加上will you或won't you构成反意疑问句,用will you 多表示“请求”,用won't you 多表示提醒对方注意。如:
Let引导的祈使句有两种情况:
1) Let's...,后的反意疑问句用shall we或shan't we。
2)Let us/me...后的反意疑问句用will you或won't you。
3)祈使句都用will you 或won’t you
2.当陈述部分含I think (believe, suppose...)that... 结构时,其反意疑问句须与从句的主、谓语保持一致,注意主句的主语必须是第一人称。
3.当陈述部分含有以下这些含有否定意义的词时:few, little, seldom,hardly, never, not, no, no one, nobody, nothing, none, neither等,其反意疑问句需用肯定结构。
4.陈述部分的主语是everything, nothing, anything或something 时,反意疑问句的主语应用代词it。
5.陈述部分是there be句型时,其反意疑问句中要用there。
6.陈述部分有had better时,反意疑问句中要用hadn't。
7.当陈述部分含有情态动词must时,我们便要分析一下must的含义。如果must 作“一定;要;必须”讲,反意疑问句须用mustn't或needn't;而当must作推测意义“一定是;必定”讲时,反意疑问句则需根据must后的动词原形选用相应的形式-

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。
11.4 一般将来时

如:
Which paragraph shall I read first? 我先读哪一段呢?
Will you be at home at seven this evening? 今晚七点回家好吗?
2) be going to +不定式,表示将来。

11.6 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。例如:
I am to play football tomorrow afternoon. 明天下午我去踢球。(客观安排)

明天下午我想去踢球。(主观安排)
11.7 一般现在时表将来
1)下列动词come, go, arrive, leave, start, begin,
return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情。例如:
The train leaves at six tomorrow morning. 火车明天上午六点开。
When does the bus star? It stars in ten minutes. 汽车什么时候开?十分钟后。
2)以here, there等开始的倒装句,表示动作正在进行。例如:

下列动词come, go, arrive, leave, start, begin,
return等现在进行时可以表示将来。例如:
I'm leaving tomorrow. 明天我要走了。
Are you staying here till next week? 你会在这儿呆到下周吗?
11.9 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。
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.
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。
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

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。

⑩ 初中英语语法重点有哪些
主要是宾语从句和状语从句,如果说考的稍微难一些的话就是定语从句以及名词性从句,一般考的话后两者的难度不会很大.
宾语从句在句中作及物动词或介词的宾语,从句放在主句之后,前后不用逗号分开.
宾语从句:
引导宾语从句的词有:
连词that(在口语中that常可省略),if,whether,如:
He knows that Jim will work hard.
连接代词who,whom,which等,如:
Do you know who (whom) they are waiting for?
连接副词when,where,how,why等,如:Could you tell me how we can get to the station?
3.whether和if都有“是否”的意思,一般情况下两者可以换用,但在介词之后,
不定式之前,与or not连用,在句首或在引导表语从句,同位语从句时,只能用whether,如:I want to know if/whether the news is true.He doesn't know whether to stay or not?
4.宾语从句要用陈述句语序.
5.宾语从句一定要注意时态呼应,即:当主句谓语动词是过去式时,从句中谓语动
词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,其谓语的时态仍用一般现在时,如:
He asked who could answer the question.
My father told me that the earth goes around the sun.
