㈠ 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

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-
