状语从句和宾语从句练习

发布时间:2013-12-14 16:44:09  

because, as, for, since这几个词都是表示“原因”的连词,语气由强至弱依次为:because→since→as→for;其中because, since, as均为从属连词,引导原因状语从句;而for 是并列连词,引导并列句。

2. since侧重主句,从句表示显然的或已为人所知的理由,常译为“因为”、“既然”,语气比because稍弱,通常置于句首,表示一种含有勉强语气的原因。

3. as是常用词,它表示的“原因”是双方已知的事实或显而易见的原因,或者理由不是很重要,含义与since相同,但语气更弱,没有since正式,常译为“由于,鉴于”。从句说明原因,主句说明结果,主从并重。例如: (1)We all like her as she is kind. 我们都喜欢她,因为她善良。

4. for用作连词时,与because相似,但它所表示的原因往往提供上文未交待过的情况。for不表示直接原因,表明附加或推断的理由,因此for被看作等立连词,它所引导的分句只能放在句子后部(或单独成为一个句子),并且前后两个分句间的逻辑关系不一定是因果关系,其间用逗号隔开,且for不可置于句首,for的这一用法常用在书面语中,较正式。例如: It must have rained, for the ground is wet. (从“地面潮湿”作出“下过雨”的推测,但地湿并不一定是下雨所致, for不可以换为because。) The ground is wet because it has rained. (“下雨”是“地上潮湿”的直接原因。)

前后两个分句间有一定的因果关系时(有时很难区分是直接原因,还是推测性原因),for与because可以互换使用。例如:

(4)I could not go, for / because I was ill. 我没能去,是因为我病了。

二.Because/as because 引导的是必然原因,as引导一般原因。

必然原因是指某事发生必会导致另一件事实。一般原因语气还有其因果关系不是很明显。以下两个句子请体会 The floor is wet,because it rained this morning.

As the floor is wet, it might rain this morning.(地板湿也可能是其他原因,以此看,as引导原因从句还有猜测的意味。) Because/for

这两个词的意思很相近,通常是可以互换使用的。为了安全起见,最好用because引导从句,因为同because引导的从句相比,for引导的从句(英文中称为for-clause)的用法要受到某些限制:

1 for引导的从句不能位于它所解释的动词之前:

Because it was wet he took a taxi.

因为下雨,他叫了一辆出租车。(这里不能用 for。)

2 for引导的从句不能位于not,but或任何连词之后:

He stole,not because he wanted the money but because he liked stealing.

他偷东西,并不是因为他想要钱,而是他有这种毛病。(这里不能用for。)

3 for引导的从句不能用于回答问题:

—Why did you do it? —I did it because I was angry.

—你为什么这么做? —因为我生气才这么做的。(这里不能用for。)

4 for引导的从句不能单单用来复述已讲过的话,而必须包括新的内容:

He spoke in French.She was angry because he had spoken in French.

他讲法语。因为他讲法语,她生气了。(这里不能用for。)但是可以说:

She was angry,for she didn’t know French.她生气了,因为她不懂法语。(这里用for是正确的,也可用because。)之所以有这些用法上的限定,其理由是for引导的从句不能直接说明某一特定动作发生的原因,而只能提供一些起帮助解释作用的附加说明。

例句如:The days were short,for it was now December.天短了,现在已是12月了。

He took the food eagerly,for he has eaten nothing since dawn.他狼吞虎咽地吃了起来,因为他从天亮就没吃过东西。

定语从句的基本结构为:先行词 + 关系代/副词 + 句子 考点1. 关系代词: that, which, who, whom, whose 关系副词: when, where, why.

a. that-既可指人,也可指物,作主语,不能省略;作宾语,可以省略;不引导非限定性定语从句

There are lots of things ________ I need to prepare before the trip. A. who B. that C. whom D. whose

b. which-指物,作主语,不能省略;作宾语,可以省略.可引导非限定性定语从句。

This is the dictionary ________ Mum gave me for my birthday. A. which B. what C. whose D. whom

Sorry, we don’t have the coat ________ you need. A. what B. who C. whom D. which

c. who-般指人,作主语,不能省略;作宾语,可以省略,(常用whom)

Jamie is a young cook ________ wants to improve school dinners.

A. who B. whose C. whom D. which d. whose 作定语,表示所属关系。

I like the teacher ________ classes are very interesting and creative. A. which B. who C. what D. whose

e. when 作时间状语:When =介词 + which

She will never forget the day when (=on which) she was married.

f. where 作地点状语 where = 介词 + which

I want to know the place where (= in which) I was born.

g. why 作原因状语, 其先行词常常是the reason. why = for which

That is the reason why(= for which) I’m late.

2. 当关系代词在定语从句中作主语时,定语从句的谓语动词形式由先行词定。

1. I prefer shoes that are cool.

2. I like a pizza that is really delicious.

3. 有时只能用 that , 不用 which, 常见的情况有六种:

1).当先行词是 all, any, few, little, none, anything, everything, nothing ,或被它们修饰时。

That’s all that I know. Is there anything that I can do for you?

2).当先行词被形容词最高级或序数词修饰That is the most interesting book that I have ever read.

3).当先行词有the very, the only, the same等修饰时。

That’s the only thing that I can do now. These are the very words that he used.

4).当主句以 who 或 which开头时,定语从句的关系词用 that, 而不用 which 或 who.

Who is the girl that spoke to you just now? Which is the pen that you lost ?

5).先行词同时包括人或物时,关系词用that.

The man and his dog that I always meet are standing by the gate.

6).当关系代词在从句中作表语时。China is not the country that it was.

4. 只用 which ,不用that 的情况:1).关系代词前有介词时。This is the cage that / which Polly lives in.

= This is the cage in which(where) Polly lives . 2).先行词本身为 that. The clock is that which tells the time.

3). 在非限制性定语从句中。His English, which used to be poor , is excellent now.
