　　句型梳理

　　[即境活用]

　　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)

　　a．so a well­known　　　 b．a so well­known
　　c．such well­known a  d．such a well­known

　　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)

　　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)
