句型梳理
1【教材原句】 As time went by,I was made smaller.(P18)
随着时间的流逝,我被做得更小了。
【句法分析】 as意为“随着”,引导时间状语从句。
①As we grow older,we get wiser.
随着年龄的增长,我们会变得越来越聪明。
②As time went on,Einstein’s theory proved to be correct.
随着岁月的推移,爱因斯坦的理论被证明是正确的。
[易混辨析]
as,with
(1)as是连词,引导时间状语从句。
(2)with是介词,后接名词或代词构成with短语或with复合结构。
①As our life improves,we find more and more time entertaining.
②With the time going by,they became close friends.
[即境活用] 
11.________children get older,they become more and more interested in the things around them.
A.While         B.When
C.As D.With
解析:选C。as可表示两个同步发展的动作或行
为,意为“随着”;while表示一段较长的时间或过程内主从句谓语动作同时发生;when作“当……的时候”讲,指较短的一段时间或点时间;with不能引导从句。
12.I couldn’t do my homework with all that noise________.
A.going on B.goes on
C.went on D.to go on
解析:选A。with复合结构在句子中作伴随状语。“with+n.+doing/done/介词短语”为固定结构。noise与go on之间为主动关系,故选A。
2【教材原句】 And my memory became so large that even I couldn’t believe it!(P18)
我的存储量变得如此之大,连我自己都不能相信!
【句法分析】 so/such...that引导结果状语从句,意为“如此……以至于”。
so...that...的基本句式:
(1)so+形容词(副词或分词)+that从句

(The teacher spoke so fast that I couldn’t follow him.)
那个老师说得太快,我听不懂。
[即境活用] 
13.(2009年高考上海卷)The Great Wall is________tourist attraction that millions of people pour in every year.
A.so a well­known    B.a so well­known
C.such well­known a D.such a well­known
解析:选D。句意:长城是如此著名的旅游胜地,以至于每年都有上百万人涌来。such+a+形容词+单数名词+that从句,表示“如此……以至于……”。
14.(2009年高考重庆卷)Peter was so excited________he received an invitation from his friend to visit Chongqing.
A.where B.that
C.why D.when
解析:选D。句意:当彼得的朋友邀请他来重庆时,他很兴奋。此题考查状语从句,只有when引导的时间状语从句符合题意。
复合句
◆什么是复合句
复合句由一个主句和一个或多个从句组成,主句表达的是重要信息,从句起到补充修饰的作用。一个组织严密的复合句通常在包含大量信息的同时,还要正确地反映信息间的逻辑关系。
【佳句选粹】
①There is a rumor that he has married a widow.
【分析】 本句属于复合句,由“主句+同位语从句”构成。“he has married a widow”作为“rumor” 的同位语,由that引导构成了同位语从句。
②Let’s meet tomorrow if it is convenient for you.
【分析】 本句属于复合句,由“主句+条件状语从句”构成。“Let’s meet tomorrow”是主句,“if it is convenient for you”是由if引导的条件状语从句。
◆主要从句类型
英语中的从句有很多类型,因此除了准确判断句子之间的主从关系以外,还要熟悉和掌握各种不同类型的从句。
1.名词性从句:它在句子中可充当主语、宾语、表语、同位语等。
【佳句选粹】
①How it all happened is a mystery to me.
这一切是怎样发生的对我来说是个谜。(主语)
②I wonder if you could stay for another day.
不知你可否再待一天。(宾语)
③The question is whether they have signed a contract.
问题是他们签没签合同。(表语)
④The idea that money means everything is unsound.
金钱万能的思想是错误的。(同位语)
2.定语从句:多由关系代词或关系副词引导。
【佳句选粹】
①Jim introduced me to a girl who sat next to him.
吉姆把我介绍给他旁边的一位姑娘。
②Then I telephoned the doctor (whom)she had recommended.然后我给她推荐的医生打了电话。
③There are the reasons why we did it.
这些就是我们这样做的原因。
3.状语从句:用作状语的从句很多,可以表示时间、地点、原因、条件、方式、目的、结果、比较、让步等。
【佳句选粹】
①We all stood up when he came in.
他进来时我们都站了起来。(时间)
②I didn’t go because I wasn’t feeling well.
我没有去是因为我身体不舒服。(原因)
③It was so dark that we couldn’t see each other’s faces.
天那样黑,我们看不清彼此的脸。(结果)
④Though they were poor,they were still happy.
他们虽然很穷,但仍然很幸福。(让步)
⑤Just as the water is the most important of liquids,air is the most important of gases.
正如水是液体中最重要的一种一样,空气是气体中最重要的一种。(方式)
⑥You’ll do all right,as long as you follow his advice.
只要你听从他的劝告,你就会干得很好。(条件)
⑦The director gave me a better offer than he gave Dick.
导师给我的提议比给狄克的好。(比较)
