故选D。

10．With the world changing fast，we have something new________with all by ourselves every day.

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]

(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”。

(1)so＋形容词(副词或分词)＋that从句

那个老师说得太快，我听不懂。

[即境活用]
13．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．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)。
