虚拟语气

虚拟语气也是一个难点。所谓虚拟语气是表示说话人的愿望、假设、猜测或建议，而不表示客观存在的事实。它通过句子的谓语动词的特殊形式来表示。

现归纳如下：纯假设，用虚拟，动词时态退一级：条件句，分主从，主句谓语前加would

(should,could，might);表愿望,用虚拟，wish后面接宾语(从句)：现在过去与将来，动词时态退一级：提建议，用虚拟，宾语(从句)动词用(should)do：俩建议，三要求，再加坚持与命令

(suggest,advise,demand,require,request,insist,order)：It is time和eoukd

rather,后接丛句用虚拟：部分主语从句中， 谓语用虚拟结构 (It is necessry

/important/natural/natural/strange/strange that??should do)。 下面举例说明：

A、If you came tomorrow,we would have the metting. (条件句虚拟)

B、Without air,there would be no living things.(同上)

C、We wish we had arrived there two hours earlier.(表示愿望虚拟)

D、He demanded that we (should)start right away.(表示建议虚拟)

E、It is(high)time that we left (should leave)now.(特殊从句虚拟)

F、I would rather you gave me the book.(同上)

G、It is necessary that we should clean the room everyday，(主语从句虚拟) H、He

speaks English so fluently as if he were English. (特殊从句虚拟)

情态动词与助动词

1、can能，可以，表说话人同意，许可还可表客观条件许可，如:You can go now.

提建议或请求时可用can I, can you表客气，如Can I buy you a drink?

can和be able to表能力时的区别。

can表一般具有的能力，be able to表在特定条件下的能力，如:Although the driver was badly hurt,he wasable to explain what had happened.

2、may

(1)可以，表说话人同意，许可或请求对方许可。You may go.

(2)(现在和将来)可能，也许，只用于肯定句和否定句中，如He may not be right.

3、must,have to

must表主观上的必须，have to表客观上的必须，如:It's getting late. I have to go. -Must I go now.-Yes,you must.(No, you needn't./ No, you don't have to.)

4、need,dare这二词有实意动词和情态动词两种词性，如用作实意动词后接动词不定式to do，如用作情态动词后接动词原形。Need I go now? --Yes, you must./No, you needn't.)

5、shall用于第一人称疑问句中表说话人征求对方的意见或向对方请求，如，Shall we begin our lesson?用于二、三人称陈述句，表说话人命令、警告、允诺、威胁等口吻，如: You shall fail if you don't workharder.

6、should表应该，意为有责任，有义务。如:We should try our best to make our country more beautiful.

7、will表有做某事的意志、意愿、安心、打算，如"Will you lend me your book?" "Yes, I will."

8、should have done表应该做而未做

must have done表对过去事实的肯定推测

could have done表本可以做某事

9、判断句：肯定句用must, 否定句用can't,不太肯定用may,might

He must be in the office now.

He must have gone to bed, for the light is out.

He can't be in the office. He is at home.

He couldn't have cleaned the classroom, because he didn't come here today.

He might be in the office, I am not sure.

He might have cleaned the room, I suppose.

让步状语从句

1、though,although,as的区别

A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。

B、though引导的从句可以倒装，也可以不倒装;as引导的从句必须倒装;although引导的从句不能倒装。其结构为：形容词/分词/副词/动词原形/名词(无冠词)+as/though+主语+谓语……

2、though可用作副词，放在句末，意为“不过，但是”。Although无此用法。

3、某些短语也引导让步的从句或短语，意为“尽管”，如：in spite of the fact that, despite the fact that,regardless of(the fact that)

句子种类

1、陈述句的否定

(1)在含有宾语从句的主从复合句中，当主句的谓语动词是think, expect, believe, suppose, guess, fancy,imagine等，且主句主语是第一人称时，宾语从句谓语的否定习惯上要移到主句谓语上，如: I don't think he is right.

(2)含有否定意义的副词never, seldom, hardly, scarcely, rarely, barely的句子应视为否定句，如: I have never been there before.

2、反意疑问句

(1)need和dare 既可作情态动词，又可作实意动词，在反问部分须加以区别，如We needn't leave, need we? We don't need to leave, do we?

(2)陈述部分出现否定意义的副词或代词如never, seldom, few, hardly, little等时，反问部分须用肯定形式，如：He seldom comes, does he?

(3)陈述部分用不定代词作主语时，反问部分的主语用it ，如：Nothing can stop me, can it?

陈述部分用everybody, everyone, somebody, someone，等作主语时，反问部分常用it，有时也用they，如:Everybody knows that, don't they?

(4)陈述部分包括used to 时，反问部分可有两种形式，如: You used to get up early, usedn't (didn't) you?

(5)陈述部分是"there + be"结构时，反问部分用there，如:There's something wrong with you, isn't there?

(6)陈述部分是含有宾语从句的主从复合句时，反问部分的主语和谓语应和主句保持一致，如: He never told others what he thought, did he?

但，如果是I think , I believe等+宾语从句时，反问部分须和从句的动词保持一致，如，I don't think he is right, is he? I don't believe he does that, does he?

3、感叹句

用what或how,

What a beautiful park it is.

How beautiful a park it is.

How beautiful the park is.

How we worked!

4、祈使句

Take care!

Don't stand there.

Please open the door for the old lady.
