1、1复合句 名词性从句 Noun Clause一、复合句的定义复合句又称主从复合句,由一个主句和一个或一个以上的从句构成,主句为句子的主体,从句不能独立,只用作句子的一个成分,如主语、表语、宾语、介词宾语、定语、同位语、状语(包括地点、条件、时间、原因、让步、比较、结果等状语) 。从句担任什么句子成分,这个从句就叫做该成分的从句,如主语从句、表语从句、宾语从句等。二、名词性从句的定义和分类名词性从句相当于名词,可作主句的主语、表语、宾语和同位语。因此名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。三、名词性从句的连接词名词性从句的连接词分为从属连词、连接代词和连接副词。从属连词 tha

(定语从句,无 that,有逗号)上两句意为“据报道,美国遭到恐怖分子的袭击”。必背用形式主语 it 引导的主语从句相当多,有些已形成固定的语法和译法。常见的有:It is said that. 据说 It is reported that. 据报道 It is well k

30、主语、宾语、表语等。这种用法中,whatever,whoever 在从句中通常不含疑问意义。Whatever=anything that;whoever=anyone who,要注意 whatever 和 whoever 引导的让步状语从句的区别,Whoever breaks the law should be punished.(主语从句)=Anyone who breaks the law should be punished. 不管是谁犯了法,都应该受到惩罚。Whoever breaks the law, he should be punished.(让步状语从句,主句和从句都有自己独立

34、ere 等也可引导同位语从句。如:He gave us many suggestions that we (should) get up earlier and take more exercise.他给我们提了很多建议,如:早起,多锻炼等。The news that Beijing won the bid to hold the 2008 Olympic Games greatly encouraged us. 北京获得 2008 年奥运会举办全的消息极大地鼓舞了我们。I have no idea where he comes from. 我不知道他是什么地方人。He cant answer
35、 the question how he got the money.他不能回答他是怎样弄到这笔钱的问题。2.同位语从句与定语从句的区别定语从句是先行词的修饰语,它不涉及先行词的具体内容。如果定语从句由 that 引导,that 在从句中不但起连接作用,而且在定语从句中充当一个句子成分。同位语从句对中心词的内容进行进一步地解释和说明,表明中心词的具体实际内容。引导同位语从句的 that 在同位语从句中不作任何成分,只起连接作用,无词义,且不可省略。比较:We expressed the hope (that) they had expressed.我们表达了他们曾经表达了的希望。 (that
36、引导定语从句, that 可省略)We expressed the hope that they would come to China again.我们表达了这样的希望:欢迎他们再来中国。 (that 引导同位语从句, that 不可省略)The information has been announced that more middle school graduates will be admitted into universities.将会有更多的高中毕业生被大学录取的信息已公布出来了。 (that 引导一个间隔式同位语从句,修饰 information)9The informati
