ection Ⅱ　Grammar 同位语从句 1.同位语从句的语法意义 在句中做同位语的从句为同位语从句。同位语从句一般跟在某些名词的后面,用以解释或说明前面名词的内容。后面能接同位语从句的名词有fact,news,message,doubt,idea,reply,belief,hope,thought,promise,suggestion,question,demand,order等。 2.同位语从句的类型 引导同位语从句的词有连词that,whether,疑问代词who,which,what和疑问副词where,when,why,how等。 (1)由连词that,whether引导的同位语从句。 They were all very much worried over the fact that you were sick. 他们都对你生病这件事很焦虑。 The problem whether he will be sentenced for drunk driving isn’t clear. 他是否因酒驾判刑这一问题还不清楚。 语法指南 (2)由疑问代词who,which,what等引导的同位语从句。疑问代词在从句中做主语、宾语或定语。 We had no idea who on earth did it. 我们不知道究竟是谁干的这事。(who在从句中做主语) We felt sad at the thought what he did and said. 一想起他的所说所为我们就感到难过。(what在从句中做宾语) I have no idea which one I should choose. 我不知道该选哪一个。(which在从句中做定语) (3)由疑问副词when,where,why,how等引导的同位语从句。疑问副词在从句中做时间状语、地点状语、原因状语和方式状语。 I have no idea when he will be back from Shanghai. 我不知道他何时从上海回来。(when在从句中做时间状语) The question where we will go to spend our holiday has not been discussed. 我们要去哪里度假这一问题还没讨论。(where在从句中做地点状语) I’ve got a pretty good idea why they left early. 我非常了解他们为什么离开得那么早。(why在从句中做原因状语) It remains a mystery how it happened. 那事是怎么发生的仍然是个谜。(how在从句中做方式状语) 3.同位语从句应注意的几个问题 (1)表达“是否”的概念时,要用whether而不用if引导同位语从句。 I have no idea whether you are interested in working for her.我不知道你是否有兴趣为她工作。 (2)分隔式同位语从句:有时同位语从句与其所解释说明的词被其他成分分开。 His promise was along with the letter that he would visit me this coming Christmas. 信中他承诺在即将到来的圣诞节他会来拜访我。 (3)在某些名词后的同位语从句中,其谓语动词应用虚拟语气形式:(should+)动词原形。常见的这类名词有:advice,order,demand,plan,proposal,suggestion(建议),request,requirement,decision,recommendation等。 The suggestion that a new bridge (should) be built was accepted.修建一座新桥的建议被采纳了。 (4)名词doubt(怀疑)后的同位语从句用whether引导;no doubt(毫无疑问)之后的同位语从句用that引导。 We have some doubt whether they can complete the task on time.我们怀疑他们能否按时完成任务。 There is no doubt that he will keep his promise. 他会遵守他的诺言,这一点是毫无疑问的。 4.同位语从句与定语从句的区别 (1)同位语从句对同位词作进一步的解释或补充说明;而定语从句对先行词起修饰或限制的作用。 The foreigner expressed the hope that he would come to China again.(同位语从句) I’ll
