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
一．非谓语动词 一．不定式：
一）不定式的常考形式：
一般形式：He decided to work harder in order to catch up with the others.被动形式: He preferred to be aigned some heavier work to do.语法功能： 表示与谓语动词同步发生l 成形式：He pretended not to have seen me.被动形式：The book is said to have been translated into many languages.语法功能：表示发生在谓语动词之前 二）不定式常考的考点： 1）不定式做定语----将要发生 2）不定式做状语----目的
3）不定式充当名词功能---To see is to believe.三)不定式的省略
1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel + do 表示动作的完整性，真实性； + doing 表示动作的连续性，进行性 I saw him work in the garden yesterday.昨天我看见他在花园里干活了。(强调\"我看见了\"这个事实) I saw him working in the garden yesterday.昨天我见他正在花园里干活。（强调\"我见他正干活\"这个动作）
感官动词后面接形容词而不是副词：The cake tastes good; It feels comfortable.2) 使役动词 have bid make let 等词后不定式要省略但同1)一样被动以后要还原to I ‘d like to have John do it.I have my package weighed.Paul doesn’t have to be made to learn.3) help help sb do help sb to do help do help to do 四)有些动词后只跟不定式如：
want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect allow sb to do, cause sb to do , permit sb to do, enable sb to do force sb to do.be more likely to do love to do warn sb to do be able to do be ambitious to do.begin to do .start to do 五) 有的时候to后面要接-ing形式
accustom (oneself) to; be accustomed to; face up to; in addition to; look forward to; object to; be reduced to; resign oneself to; be resigned to; resort to; sink to; be used to; be alternative to; be close/closene to; be dedication/dedicated to; be opposition/opposed to; be similarity/similar to.
三、need/want 后的-ing形式具有被动的意思。其中，want不太常用。 He needs (a lot of) encouraging.1)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.2)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 I’d been working for some time when he called.We had been waiting for her for two hours by the time she came.3)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.In another month’s time she’ll have been studying here for three years.4)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.可以有两种被动结构的类型,例如: He was said to be jealous of her succe.It was said that he was jealous of her succe.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aume,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.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.例如: 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) 双宾语及宾补结构的被动语态
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 pre conference.Two days were allowed them for making the neceary preparations.宾补结构的被动语态: She was called Big Sister by everybody.Then he was made a squad leader.He was considered quite qualified for the job.The room was always kept clean and tidy.短语动词 Vi + adv The plane took off two hours late.Vi + prep They looked round the Cathedral.Vi + prep (有被动语态) She’s looking after her sister’s children.The children were always well looked after.Vi + adv + prep I began to look forward to their visits.Vt + O + adv Some women choose to stay at home and bring up their children.The children were brought up by their mother.They took him on.Vt + adv + O (无被动语态) I am trying to give up smoking.Vt + O + prep We talked Donald into agreement.在以as, than, when, if, unle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.Look out for cars when croing the street.When taken according to the directions, the drug has no side effects.While there he joined in voluntary labour on a project.Although not yet six months old, she was able to walk without support.If not well managed, irrigation can be harmful.Though reduced in numbers, they gained in fighting capacity.This viewpoint, however understandable, is wrong.Enemies, once discovered, were tightly encircled and completely wiped out.She hurriedly left the room as though/if angry.She worked extremely hard though still rather poor in health.Fill in the application as instructed.Whenever known, such facts should be reported.The documents will be returned as soon as signed.He said that no acrobat could ever perform those daring feats unle trained very young.Once having made a promise, you should keep it.If neceary I’ll have the letter duplicated.Fill in the blanks with articles where(ver) neceary.If poible, I should like to have two copies of it.As scheduled, they met on January 20 at the Chinese Embay.在以than a) 或 as b) 引起的从句中,常会有一些成分省略.He told me not to use more material than (it is) neceary.We should think more of the collective than of ourselves.They worked with as much enthusiasm as young people (did).He is now a vice-manager, but still often works in the kitchen as before.Their training is free, as is all education.We will, as always, stand on your side.错误的省略

They insisted on my staying there for supper.如果不是在句子开头, 这个结构常常可以用名词的普通格(或人称代词宾格), 这比用所有格更自然一些.I don’t mind him going.She hates people losing their temper.只能用动名词作宾语的动词: suggest, finish, avoid, stop, can’t help, mind, admit, enjoy, leave off, require, postpone, put off, delay, practise, fancy, excuse, pardon, advise, consider, deny, endure, escape, mi 既可用动名词, 也可用不定式作宾语的动词: love, like, hate, dislike, begin, start, continue, intend, attempt, can’t bear, propose, want, need, remember, forget, regret, neglect, try, deserve, can’t afford等.有时两种结构之间意义差别不大, 有时却有不同的意思.在remember, regret, want, try等词后差别是比较明显的.I remember seeing her once somewhere.I must remember to take my notebooks with me.I regret not having accepted your advice.I regret to say I haven’t given you enough help.She doesn’t want (need) to come.The house wants (needs) cleaning.We must try to get everything done in time.Let’s try doing the work some other way.悬垂修饰: 分词作状语时, 表示的必须是主语的一个动作或状态.Walking through the park, we saw a lot of flowers.(walking是we的动作, 正确) Walking through the park, the flowers looked very beautiful.(错误) Standing on the tower, we could see the whole city.(正确) Standing on the tower, the whole village could be seen.(错误)
一、宾语从句 (Object Clause)
宾语从句为肯定句（由that 引导），在口语中that常省略。
（1）当主句中谓语动词是现在或将来时态时，从句中谓语动词不受主句中谓语动词时态的影响，按需要可以使用任何时态。如：
She says (that) she works from Monday to Friday.（从句是一般现在时）
She says (that) she will leave a meage on his desk.（从句是一般将来时）
She says (that) she has never been to Mount Emei.（从句是现在完成时）
（2）当主句谓语是过去时态，从句中的时态一般用表示过去的某种时态。如：
He said there were no claes yesterday afternoon.（从句是一般过去时）
He said (that) he was going to take care of the baby.（从句是过去将来时）
He said (that) they were having a meeting at that time.（从句是过去进行时）
注意：当主句谓语是过去时态，而宾语从句叙述某一客观真理（事实）时，宾语从句的时态则用一般现在时。
The teacher told us (that) nothing is difficult if you put your heart into it.
老师告诉我们世上无难事只怕有心人。
He said that light travels much faster than sound.他说光传播比声音传播快得多。
宾语部分为一般疑问句（由whether引导）
“Can you help me?” He asked.
He asked whether (if) I could help him.
She asked, “Will Lao Li come to my birthday party?”
She asked whether (if) Lao Li would come to her birthday party.
注意：在将一般疑问句转变成宾语从句时，一定要注意陈述句语序。
