篇1：大学英语四级语法精要：非谓语动词的功用

非谓语动词的功用: 不定式可以作主语 (a), 宾语 (b), 表语 (c), 定语 (d) 或是状语 (e).

a. To scold her would not be just.

b. We are planning to build a reservoir here.

c. One of our main tasks now is to mechanize agriculture.

d. Do you have anything to declare?

e. We have come to learn from you.

篇2：大学英语四级语法精要：非谓语动词的被动式

非谓语动词的被动式: 当不定式的逻辑上的主语是不定式所表示的动作的承受者时, 不定式一般要用被动形式.

It is an honour for me to be asked to speak here.

She hated to be flattered.

He wanted the letter to be typed at once.

This is bound to be found out.

There are a lot of things to be done.

She was too young to be assigned such work.

篇3：大学英语四级语法精要：非谓语动词的完成进行式

非谓语动词的完成进行式: 在谓语所表示的时间之前一直进行的动作, 就要用不定式的完成进行式.

The struggle was known to have been going for twenty years.

We are happy to have been working with you.

篇4：大学英语四级语法精要：动词

动词

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, miss

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)

篇5：大学英语四级语法精要：情态动词（二）

can’t, couldn’t表示否定的推测:

She can’t be serious.

A more suitable book can’t be found. (It is not possible to find a more suitable book.)

He couldn’t (can’t) be over fifty.

篇6：大学英语四级语法精要：情态动词（四）

情态动词后接进行式, 完成式和完成进行式:

a) 情态动词可以和动词的进行式构成谓语, 表示”应该正在…”, “想必正在…”这类意思:

Why should we be sitting here doing nothing?

This isn’t what I ought to be doing.

She might still be thinking about the question you raised.

They must (may) be waiting for us, let’s hurry up.

They can’t be using the room now.

b) 情态动词有时和动词的完成形式构成谓语, 表示”应当已经…”, “想必已经…”这类意思:

I should have thought of that.

They shouldn’t have left so soon.

She must have arrived by now.

You needn’t have told them that.

Where can (could) he have gone?

He can’t have finished the work so soon.

He may not have achieved all his aims. But his effort is praise-

worthy.

We ought to have give you more help.

c) 情态动词间或也可以和一个动词的完成进行式构成谓语,表示”应当一直在…”, “想必一直在…”这类意思:

They are sweating all over. They must have been working in the fields.

They may have been discussing the problem this morning.

You should have been waiting for us. Why haven’t you?

She couldn’t have been swimming all day.

篇7：大学英语四级语法精要：情态动词（三）

should, ought to: 表示应该做的事, ought to比should口气稍重一些.

You should (ought to) do as he says.

You shouldn’t (oughtn’t to) talk like that.

但这两者间也有一些差别, 在表示责任, 义务等该做的事情时, 常用ought to, 在表示某件事宜于做时, 多用should, 在下面的句子中这两个词就不宜换用:

You are his father. You ought to take care of him.

We should not use too many big words in our everyday speech.
