复习上节课主要内容

二、知识讲解

知识点1:并列连词的用法

1.表递进或顺承关系:and,not only ...but also ...,not ...but ...等。

She not only plays well,but also writes music.

她不仅演奏得很好,而且还会作曲。

2.表选择关系:or,either ...or ...等。

3.表转折关系:but,yet等。

Several people were passing but nobody offered to help.有几个人擦肩而过,却没有人提供帮助。

4.表因果关系:so,for等。

The shops were closed so I didn't get any milk.

商店都关门了,因此我没买到牛奶。

5.when作并列连词时意为“就在这个时候”。

We were having a meeting when someone broke in.

我们正在开会,这时有人闯了进来。

6.while作并列连词时意为“而,却”,表示对比。

Some men were rich, while others are poor.

一些人富有,而其他人贫穷。

知识点2:时间状语从句

1.when,while和as

(1)when从句的动作和主句的动作可以同时发生,也可以先后发生,从句谓语动词为延续性动词或非延续性动词。

When I lived there, I used to go to the seashore on Sundays.我住在那里时,星期天常到海滨去。

(2)while从句的动作与主句的动作同时发生,从句的谓语动词为延续性动词。

Please don't talk so loud while others are working.别人工作时,请别高声谈话。

(3)as从句的动作与主句动作交替进行或同时发生,可翻译为“随着;一边……一边……”。

He hurried home, looking behind as he went.

他匆忙回家去,一边走一边回头望。

As time went on, it's getting warmer and warmer.

随着时间的推移,天越来越暖和了。

2.till和until

在肯定句中主句谓语动词应是延续性的,而在否定句中主句谓语动词应是非延续性的;till不可位于句首,而until则可以。

You may stay here till/until the rain stops.

你可以待在这里直到雨停。

I won't see him till/until his anger has cooled down. 等他怒气消了,我再去看他。

Until you told me, I had no idea of it.

直到你告诉我,我才知道这件事。

3.before和since

(1)before本意为“在……之前”,还可引申为“还未……就……,不到……就……;趁……;还没来得及……就……”。常用句型It will be+一段时间+before从句,意为“还要多久才……”。

We hadn't run a mile before he felt tired.

我们跑了还不到一英里他就累了。

It won't be long before we meet again.

过不了多久我们就会再见面了。

(2)since意为“自从……以来”,主句用完成时。since引导的从句如果用非延续性动词,常某某为某一状态的终止;若用延续性动词或状态动词,则理解为某一动作的开始。

It is three years since he came to our school.

他来我们学校已经三年了。

It is three years since he smoked.

他戒烟已经三年了。

4.as soon as,immediately,directly,instantly,the moment/minute/instant,no sooner ...than ...,hardly/scarcely ...when ...等都可引导时间状语从句,表示“一……就……”。

The boy burst into tears immediately he saw his mother.这个男孩一看到他妈妈就放声大哭。

No sooner had we arrived at the station than the train left.我们一到车站,火车就离站了。

5.the first time,every/each time,next time等也可引导时间状语从句,表示“第一次;每一次;下一次”等。

Every time I was in trouble, he would come to help me.每次我处于困境,他就会来帮助我。

知识点3:地点状语从句

1.通常由where或wherever引导,可位于主句前或主句后,在句首时常含有抽象意味。

They offered to go where there were difficulties. 他们表示愿意到艰苦的地方去。

You are free to go wherever you like.

你愿意去哪里就去哪里。

2.注意区分where引导的状语从句与定语从句

You'd better make a mark where you have any questions.(状语从句)

=You'd better make a mark at the place where you have any questions.(定语从句)

你最好在有问题的地方做一下标记。 知识点4:条件状语从句

引导条件状语从句的连词有:if,unless(如果不;除非),as/so long as(只要),suppose/supposing (that)(倘若;如果),provided/providing (that)(倘若;如果),on condition that(条件是)等。

Unless he studies hard, he will never pass the examination. 他如果不努力学习,就永远不能考及格。

We can overcome the difficulties as long as we are organized.只要我们组织起来,我们就能克服困难。

You can use this room provided that you keep it clean and tidy.如果你能保持房间干净整洁,你就可以用这间房子。 知识点5:原因状语从句

because表示直接因果关系,语气最强;as,since,now that指双方都知道的原因;并列连词for也可表示原因,但只是对前面的句子起补充说明作用。

Because he was ill, he was absent from the meeting.因为他病了,所以没去开会。

Now that everyone is here, let's begin our meeting.既然大家都在这里,我们开始开会吧。

知识点6:让步状语从句

1.引导让步状语从句的连词有:although,though,while(尽管,虽然),even if,whether ...or ...,疑问词+-ever与no matter+疑问词等。

While I understand your opinion, I don't agree with you.尽管我明白你的观点,但我不赞成。

Even if it should rain tomorrow, we will continue our work. 即使明天下雨, 我们也要继续工作。

Whatever/No matter what you want to do, please look before you leap.

不管你想做什么事, 请三思而后行。

【点津】 though还可作副词用于句末,意为“可是,然而”,although则不能。

He said he would come. He didn't though.

他说他会来,可是他没来。

2.as引导的让步状语从句需采用部分倒装,有时though引导的让步状语从句也采用部分倒装。

Try as he might, he couldn't solve the problem.

尽管他尝试了, 但还是无法解决这个问题。

Child as he is, he knows a lot of the history of China.(注意child前不用冠词)

虽然他只是个孩子, 他懂得许多中国历史方面的知识。

Young though he is, he knows how to deal with such a thing.

他虽然年轻,但懂得如何处理这件事。

知识点7:目的、结果、方式状语从句

1.引导目的状语从句的连词有:so that,in order that,for fear that,in case等。

你必须按照我告诉你的方法做练习。

三、例题精析

【例题1】

If you don’t understand something, you may research, study, and talk to other people _______ you figure it out.(17XX)

A. because B. though C. until D. since

【答案】C

【解析】考查连接词的辨析。until表示“直到”,句意为“如果不理解某事,你也许会对其展开研究、学习并和别人交谈直到弄明白。”

【例题2】

If you are travelling _______the customs are really foreign to your own, please do as the Romans do.

A. in which B. what C. when D. where

【答案】D

【解析】考查地点状语从句:句意:如果你到文化风俗不熟悉的地方旅行,要入乡随俗。Where引导地点状语,相当于in the place where…,意思是:在…地方。选D。

点评:where引导地点状语从句相当于,先行词in the place where,不能和定语从句混用,这是在句中充当状语从句的,做题要分析句子成分。

【例题3】

House prices vary from place to place and are usually high _____ there are famous schools.

A. where B. since C. when D. whether

【答案】A

【解析】考查地点状语从句:句意:房价是根据地方而变化的,在名校的地方房价会很高。Where引导地点状语,相当于in the place where…,意思是:在…地方。选A。

【例题4】

_______ weather it is, we shall set out on time.

A. Whatever B. However C. Whenever D. Whether

【答案】A

【解析】考查让步状语从句。“No matter+特殊疑问句”只能引导让步状语从句;“特殊疑问句+ever”既可以引导让步状语从句,也可以引导名词性从句;本句中的whatever weather it is是一个让步状语从句。Whatever后面引导的是名词或者代词。However后面接的是形容词或者副词。句意:无论是什么天气,我们都会准时出发。B项不符合语法,CD两项与上下文的含义不相符。故A正确。

点评:本题的让步状语从句考查的是“No matter+特殊疑问句”的引导方式。该结构既可以引导让步状语从句,也可以引导名词性从句;要根据上下文的含义来选择合适的特殊疑问词的形式。

四、课堂运用

【基础】

1.If you find yourself ______ no one will help you, please call me.

A. which B. when C. where D. what

3. Many people take pills to make sure they will achieve or maintain their desired weight it will lower their life expectancy(寿命).
