表语从句一、表语从句的概念在主从复合句中,用作表语的从句叫作表语从句(predicative clause)。放在系动词之后,一般结构是“主语+系动词+表语从句”。
可接表语从句的连系动词常见的有be,feel,seem,lk,appear, sund,taste,smell等。引导表语从句的关联词有连词(that,whether,as if,as thugh,because等)、连接代词(what,whatever,wh,whever,which,whichever等)、连接副词(when,where,hw,why等)。
二、表语从句的用法1.从属连词that引导的表语从句从属连词that的用法:①无意义 ②不充当成分 ③不可省略。The truble is that we are shrt f mney.困难是我们资金短缺。My idea is that he can teach children English in this schl.我的想法是他能够在这所学校教孩子们英语。
2.从属连词whether引导的表语从句whether意为“是否”,在句中不做成分。The questin is whether we need mre ice cream.问题是我们是否还需要一些冰激凌。The key is whether we can slve the prblem urselves.关键是我们能否自己解决这个问题。温馨提示 if不能引导表语从句。
3.连接代词和连接副词引导的表语从句wh,whm,whse,what,which,whever,whatever,whichever等在从句中做主语、宾语、表语或定语,本身具有词义;而when,where,why,hw等在从句中做状语,本身具有词义。This is what we have been lking frward t fr years.这是我们多年来一直期望的。
The prblem is wh is really fit fr the hard jb.问题是谁才真正适合做这份艰苦的工作。I didn’t phne her,and that was why she gt angry with me.我没有给她打电话,那就是她对我生气的原因。Their difficulty is hw they can clear their debts.他们的困难是怎样才能还清债务。
4.because,as if/thugh等引导的表语从句I didn’t phne her,and that was because I gt angry with her.我没有给她打电话,那是因为我生她的气了。Nw it seems as thugh she had knwn Millie fr years.现在好像她认识米莉已有好多年了似的。
需要注意的问题:(1)表语从句一定要用陈述语序。My hpe is that he will keep it a secret frever.我的希望是他将永远保守秘密。That is hw mice ruin many stres f grain every year.老鼠每年就是那样毁坏大量粮食储备的。
(2)在表示建议、劝告、命令等含义的名词后的表语从句,谓语动词需用“shuld+动词原形” 表示,shuld可省略。常见的词有advice,suggestin,rder,prpsal,plan,idea等。My suggestin is that we (shuld) start early tmrrw.我的建议是我们明天一早就出发。My advice is that yu (shuld) g t aplgise t him.我的建议是你应该去向他道歉。
(3)表语从句的特殊句式The reasn that...……的原因是……(why引导定语从句,修饰 the reasn,that引导表语从句)This/That/It is because...这/那是因为……(because引导表语从句,从句表原因)This/That/It is why...这/那就是……的原因。 (why引导表语从句,从句表结果)The reasn why he didn’t cme is that he didn’t receive the invitatin.他没来的原因是他没有收到请柬。
The wman was weeping bitterly.That’s because her sn was drwned in a river.那位女士痛哭流涕,那是因为她的儿子在河中溺亡了。 (先果后因)The wman’s sn was drwned in a river.That’s why she was weeping bitterly.那位女士的儿子在河中溺亡了,那是她痛哭流涕的原因。 (先因后果)
