· CET-4 常考的三种时态：过去完成时；将来完成时；（现在/过去）完成进行时。 · 时间状语从句当中的时态： 一般过去时 所有的过去 用 一般现在时 表示 现在和将来 现在完成时 现在完成和将来完成
3、现在完成进行时态 (have/has been + -ing 分词构成): 动作或状态从过去某时开始,继续到现在,可能继续下去,也可能刚刚结束.
· I’ve been writing letters for an hour. I’ve been sitting in the garden.
4、过去完成进行时(由had been + ing分词构成): 过去某个时刻以前一直在进行的动作 · We had been waiting for her for two hours by the time she came. 5、将来完成进行时: 将来某个时刻以前一直在进行的动作. · By next summer, he will have been working here for twenty years.
6、将来完成时(由shall/will have + 过去分词构成): 将来某时会业已发生的事. · I shall have finished this one before lunch.
They’ll have hit the year’s target by the end of October. （二）语态
1、可以有两种被动结构的类型,例如: · He was said to be jealous of her success.
It was said that he was jealous of her success.
· 能同时适用于上述两个句型的主动词通常都是表示―估计‖，―相信‖等意义的动词，常见的有：assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等。 · It is supposed that the ship has been sunk. The ship is supposed to have been sunk. 2、担当be supposed to 与不定式的一般形式搭配时往往表示不同的意义。 · Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你应该晓得速度限制) 3、双宾语及宾补结构的被动语态
1）双宾语结构的被动语态: 双宾语结构变为被动语态时,可以把主动结构中的一个宾语变为
主语,另一个宾语仍然保留在谓语后面,但多数是把间接宾语变为主语。
· He was asked a number of questions at the press conference.
Two days were allowed them for making the necessary preparations. 2） 宾补结构的被动语态: · She was called Big Sister by everybody. 4、短语动词

3）Vi. + prep. (有被动语态)：She’s looking after her sister’s children. 4）Vi. + adv. + prep.：I began to look forward to their visits.
5）Vt. + O + adv.：Some women choose to stay at home and bring up their children.

6） Vt. + adv. + O (无被动语态)：I am trying to give up smoking. 7）Vt. + O + prep.：We talked Donald into agreement. （三）省略
1、在以as, than, when, if, unless等引导的从句中的省略: 在有些状语从句中,如果谓语包含有动词be,主语又和主句的主语一致a),或者主语是it b),就常常可以把从句中的主语和谓语的一部分(特别是动词be)省略掉.
1）Look out for cars when crossing the street.
When taken according to the directions, the drug has no side effects.
If not well managed, irrigation can be harmful.
Though reduced in numbers, they gained in fighting capacity.
He said that no acrobat could ever perform those daring feats unless trained very young. Once having made a promise, you should keep it. 2）If necessary I’ll have the letter duplicated.

3、错误的省略

2）While standing there in her nightgown, two bullets struck the wall beside her. （四）一致
1、主谓一致（与插入语无关）
1）主谓的分隔原则：主谓之间可以用定语从句或者省略的定语从句分隔。 2）定语从句中的主谓一致 3）随前一致：
n. + together with；as well as；including；along with；with / of；accompanied with / by 4）就近原则
5）如果主语表示的是同一个概念，同一人，同一事的时候，谓语动词用单数，这种结构的特征是and连接 的两个词只有一个冠词。 · The iron and steel industry is very important to our country. · The head master and mathematical teacher is coming. · The head master and the mathematical teacher are coming. · 类似的还有：law and order；bread and；butter black and white；To love and to be loved is …；
A lawyer and a teacher are…；A lawyer and teacher is …
6）随后原则：not A but B / not only A but also B+v.(与B一致)
7）百分比结构：most，half，rest，some，majority，one + persent；of+n1+v.（由n1决定） 8）倒装结构的主谓一致： · There be +n 由名词决定动词 · Among , between等介词位于句首引起倒装结构：Among / Between …+系动词+n. （由名词
决定动词）
9）The + adj.的主谓一致： · 当表示―一类人‖ · 当表示某一抽象概念时。例：The good is always attractive.
10） To do/doing/主从+vs. 例：More than one + n.；many a +n.；a day or two
2、如果主语是单数,尽管后面跟有with, together with, as well as, as much as, no less than, more than等引导的短语,谓语动词仍旧用单数形式. · Terry, along with her friend, goes skating every Saturday.
An expert, together with some assistants, was sent to help in this work. The captain, as well as the coaches, was disappointed in the team. 3、代词作主语时一致
1）each, either, neither和由some, any, no, every构成的复合代词,作单数看待. · Each of us has something to say. Is everybody ready? Somebody is using the phone. 2） some, few, both, many 等作复数
3） some 可后接复数,也可接单数,表示某一。none作复数看待时较多,但也有时作单数看待,
主要看说话人脑中联系想到的是复数还是单数概念, 但none 在代表不可数的东西时总是看作单数: · None of the books are easy enough for us. None of us seem to have thought of it. None (= nobody) has felt it more keenly than she did. None of this worries me.
4）all 和most 可后接复数,也可接不可数名词 (all of the…, most of the …), 动词用单数.
4、由and 或 both… and 连接名词词组时, 后用复数; 由not only…but (also), either…or, neither…nor或 or 连接的并列主语, 谓语通常和最邻近的主语一致. 1）Not only the switches but also the old writing has been changed.
My sister or my brother is likely to be at home.
Neither my wife nor I myself am able to persuade my daughter to change her mind. 2）如果一个句子是由there 或here引导, 而主语又不止一个, 谓语通常也和最邻近的那个主
语一致. · There was carved in the board a dragon and a phoenix.
Here is a pen, a few envelopes and some paper for you.
5、people, police, cattle, poultry (家禽), militia (民兵) 等通常都用作复数. 1）Cattle are grazing on the pasture.

2）有些集体名词有时作单数看待, 有时作复数看待, 主要根据意思来决定. · His family isn’t very large.

The audience were greatly moved at the words.
3）有些名词单复数同形, 可根据意思决定谓语动词的数: · This new series is beginning next month.
These new series are beginning next month. This species is now extinct. These species are now extinct.
6、表示时间, 重量, 长度, 价值等的名词, 尽管仍是复数形式, 如果作整体看待, 动词也可用单数形式 (当然用复数动词也是可以的): · Three weeks was allowed for making the necessary preparations.
One hundred li was covered in a single night. 7、其他问题
1）书名, 国家名用单数: · Tales from Shakespeare is a book by Charles Lamb. 2） 学科名, 如mathematics, economics用单数.
3） many a 或more than one 所修饰的词作主语时, 谓语动词多用单数形式: · Many a person has had that kind of experience.

5）one of those 后用单数. 在―one of + 复数名词 +关系分句‖结构中，关系分句中谓语动词的单复数形式在一般情况下有两形式，一是根据先行词采用复数形式： · Joan is one of those people who go out of their way to be helpful.
6）当one 之前与the only 等限定词和修饰语时，关系分句谓语动词根据one 而定，即采用
