(2) and连接的几个从句,第二个从句以后的从句的that不省略。 (3)在动词+it+宾语补足语+宾语从句结构中,that不省略。

2.Whether ,if 引导宾语从句:两词可互换,但是下列情形除外: (1)whether从句中有or not (2)whether从句做介词宾语

3.许多带复合宾语的句子,宾语从句经常移到句子后部,而用it做形式宾语。结构常是:

主语+动词+it+形容词/名词等宾语补足语+宾语从句

状语从句

状语从句表示状语从句指句子用作状语时,起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。

状语从句的种类

1.时间状语从句 2.地点状语从句 3.原因状语从句 4.条件状语从句 5.目的状语从句 6.让步状语从句 7.比较状语从句 8.方式状语从句 9.结果状语从句

状语从句的时态特点

一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”。

一、时间状语从句

概念:

在复合句中,由时间连接词引导的状语从句叫做时间状语从句。(在复合句中,要注意主句和从句的时态大多都要保持一致。)

要点:

时间状语从句,由以下连词引导: when while as after before as soon as since till /until by the time 在时间状语从句中,要注意时态一致。一般情况下主句是将来时的时候,从句要用一般现在时。

1.when在...的时候 2.while在...期间

3.as在...的同时;一边...一边...






5

4.after在...之后 5.before 在...之前ぃ 6.as soon as 一。。。就。。。 7.since 自。。。以来 到现在

表示自过去的一个起始时间点到目前(说话时间)为止的一段持续时间。主句一般用现在完成时,从句用一般过去时。还可以用作介词,本句从句还可以用短语:since three years ago(从三年前至今)表示。

8 till /until直到。。。

都可以作连词,连接时间状语,也可以作介词,与其它词构成介词短语,在句中作状语。(强调将一般用until)

9. by the time 到。。。为止

二、地点状语从句

概念:

地点状语从句 (adverbial clause of place) 地点状语从句一般由连接副词where, wherever等引导,已经形成了固定的句型,

要点:

由连词where和复合关系词wherever (=no matter where )引导. 例如:

句型1:

Where+地点从句,(there)+主句。 【注意】此句型通常译成“哪里„„哪里就„„”;主句在从句后面时,there可用可不用;如果主句在从句的前面时,一般都不用there。

句型2:

Anywhere/ wherever+地点从句,+主句。 【注意】anywhere本身是个副词,但是,常可以引导从句,相当于连词,意思相似于wherever, anywhere引导的从句可位于主句之前,也可以位于主句之后。 而wherever本身就是个连词,表示“在何处,无论何处”。

三、条件状语从句

要点: 条件状语从句由连词if, unless (=if not) 引导。

四、原因状语从句

要点: 由连词because, since, as引导, 也可由for, now that 等词引导 1) because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而






6

易见的或已为人们所知,就用as或 since。

2) 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。

3) as和for的区别:通常情况下,as引导的从句在主句前,for引导的从句在主句后。

五、目的状语从句

要点: 目的状语从句由连词that, so that, so„that , in order that 引导。 1.so that 以至, 以便 2.in order that=so that:为了 3.despite= in spite of

六、结果状语从句

要点:结果状语从句由连词( so )that, so„that, such„that, so much/many„that引导。

1.so„that 如此„以至于 2.such„that 如此。。。以至

3.比较:so和 such 其规律由so与such的不同词性决定。such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little(这四个形容词表多或表少时)连用,形成固定搭配。 so foolish such a fool so nice a flower such a nice flower so many / few flowers such nice flowers so much / little money. such rapid progress so many people such a lot of people ( so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配。) so„that与such„that之间的转换既为 so与such之间的转换。

七、让步状语从句

要点: 表示让步的状语从句由连词 though, although引导. 注意:

a. 句首名词不能带任何冠词。

b. 句首是实义动词,其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。

八、比较状语从句

要点:比较状语从句主要运用于形容词和副词的原级,比较级及最高级的句子之中。

原级

as„as 和。。。一样

比较级






7

more„than (更)

最高级

1.The most„in/of

2. the + 形容词+est„of/in

九、方式状语从句

方式状语从句通常由as, (just) as„so„, as if, as though引导。

1) as, (just) as„so„引导的方式状语从句通常位于主句后,但在(just) as„so„结构中位于句首,这时as从句带有比喻的含义,意思是"正如„","就像",多用于正式文体,

2) as if, as though 两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。汉译常作"仿佛„„似的","好像„„似的"

附加疑问句

概念

附加疑问句由陈述句加简短附加问句构成,用以要求对方证实所述之事。附加疑问句主要有两种:一类是反意的附加疑问句,另一类是非反意附加疑问句。

反意疑问句

1 英语中,反意疑问句是由陈述句和附在其后的附加疑问句组成。其中附加疑问句是对陈述句所说的事实或观点提出疑问,起证实作用,一般用于证实说话者所说的事实或观点。

2、反意疑问句用法说明 ◇注意: 反意疑问句前后两部分谓语应是,“肯定陈述+否定疑问”或“否定陈述+肯定疑问” 简略问句如果是否定式,not应与be,do,will等系动词、助动词、情态动词缩写 简略问句的主语不用名词,应用人称代词 当说话者的目的不在疑问,而是为了加强语气时,用降调 当说话者的目的在疑问,则用升调 陈述部分含“too...to”时,是否定句

用法

1) 陈述部分的主语是I,疑问部分要用 aren't I.

2) 陈述部分的谓语是wish,疑问部分要用may +主语。

3) 陈述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, little等否定含义的词时,疑问部分用肯定含义。

4) 含有ought to 的反意疑问句,陈述部分是肯定的,疑问部分用shouldn't / oughtn't






8

+主语。正式文体用should/ought +主语+not形式。

5) 陈述部分有have to +v. (had to + v.),疑问部分常用don't +主语(didn't +主语)。

6) 陈述部分的谓语是used to 时,疑问部分用didn't +主语或 usedn't +主语。 7) 陈述部分有had better + v. 疑问句部分用hadn't you?

8) 陈述部分有would rather +v.,疑问部分多用 wouldn't +主语。 9) 陈述部分有You'd like to +v. 疑问部分用wouldn't +主语。 10) 陈述部分有must 的疑问句,疑问部分根据实际情况而定。 11) 感叹句中,疑问部分用be +主语。 12) 陈述部分由neither„ nor, either„ or 连接的并列主语时,疑问部分根据其实际逻辑意义而定。

13) 陈述部分主语是指示代词或不定代词everything, that, nothing, this, 疑问部分主语用it。

含义的词

ought to(肯定的) shouldn't/ oughtn't +主语 have to+v.(had to+v.) don't +主语(didn't +主语) used to didn't +主语或 usedn't +主语 had better + v. hadn't you would rather + v. wouldn't +主语 you'd like to + v.

情态动词用法归纳

情态动词是一种本身有一定的词义,但要与不带to的普通动词的不定式一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。
情态动词后面加动词原形。

情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语

一、 can, could

1) 表示能力(体力、知识、技能)。

Can you lift this heavy box?(体力)

Mary can speak three languages.(知识)

Can you skate?(技能)

此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to则有更多的时态。

I’ll not be able to come this afternoon.

当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。如:

He was able to go to the party yesterday evening in spite of the heavy rain.

2) 表示请求和允许。

-----Can I go now?

----- Yes, you can. / No, you can’t.

此时可与may互换。在疑问句中还可用could,

might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。

---- Could I come to see you tomorrow?

---- Yes, you can. ( No, I’m afraid not. )

3) 表示客观可能性(客观原因形成的能力)。

They’ve changed the timetable, so we can go by bus instead.

This hall can hold 500 people at least.

4) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。

Can this be true?

This can’t be done by him.

How can this be true?

二、 may, might

1) 表示请求和允许。might比 may语气更委婉,而不是过去式。否定回答时可用can’t

或mustn’t,表示“不可以,禁止”。

----Might/ May I smoke in this room?

---- No, you mustn’t.

---- May/Might I take this book out of the room?

---- Yes, you can. (No, you can’t / mustn’t. )

用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。

2)用于祈使句,表示祝愿。

May you succeed!

3) 表示推测、可能性(不用于疑问句)。

might不是过去式,它所表示的可能性比may小。

1.He may /might be very busy now.

2.Your mother may /might not know the truth.

三、 must, have to

1) 表示必须、必要。

You must come in time.

在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t, don’t have to(不必).

---- Must we hand in our exercise books today?

---- Yes, you must.

---- No, you don’t have to / you needn’t.

2) must是说话人的主观看法, 而have to则强调客观需要。Must只有一般现在时, have to 有更多的时态形式。

1. he play isn’t interesting, I really must go now.

2. I had to work when I was your age.

3) 表示推测、可能性(只用于肯定的陈述句)

1. You’re Tom’s good friend, so you must know what he likes best.

2. Your mother must be waiting for you now.

四、 dare, need

1) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。

1. How dare you say I’m unfair?

2. He daren’t speak English before such a crowd, dare he?

3. If we dared not go there that day, we couldn’t get the beautiful flowers.

2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。

1.You needn’t come so early.

2. ---- Need I finish the work today?

---- Yes, you must. / No, you needn’t.

3) dare和 need作实义动词用时, 有人称、时态和数的变化。在肯定句中,dare后面常接带to的不定式。在疑问句和否定句中,dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。

1. I dare to swim across this river.

2. He doesn’t dare (to) answer.

3. He needs to finish his homework today.

五、 shall, should

1) shall 用于第一人称,征求对方的意见。

What shall we do this evening?

2) shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。

1. You shall fail if you don’t work hard.(警告)

2. He shall have the book when I finish it.(允诺)

3. He shall be punished.(威胁)

六、 will, would

1) 表示请求、建议等,would更委婉。

Will / Would you pass me the ball, please?

2) 表示意志、愿望和决心。

1. I will never do that again.

2. They asked him if he would go abroad.

3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式,且没有“现已无此习惯”的含义。

1. During the vacation, he would visit me every other day.

2. The wound would not heal.

4) 表示估计和猜想。

It would be about ten o’clock when she left home.

七、 should, ought to

1) should, ought to表示“应该”,ought to表示义务或责任,比should语气重。

1. I should help her because she is in trouble.

2. You ought to take care of the baby.

2) 表示劝告、建议和命令。should, ought to可通用,但在疑问句中常用should。

1. You should / ought to go to class right away.

2. Should I open the window?

3) 表示推测

should , ought to (客观推测), must(主观推测)。

1.He must be home by now. (断定他已到家)

2.He ought to/should be home by now.(不太肯定)

3. This is where the oil must be.(直爽)

4. This is where the oil ought to/should be.(含蓄)
