同位语从句讲解及习题
一、理解同位语从句的含义,把握同位语从句的实质
在主从复合句中作同位语的从句称为同位语从句。同位语从句一般用that, whether,what, which, who, when, where, why, how 等词引导,常放在fact, news, idea, truth, hope, problem, information, wish, promise, answer, evidence, report, explanation, suggestion, conclusion等抽象名词后面,说明该名词的具体内容。换言之,同位语从句和所修饰的名词在内容上为同一关系,对其内容作进一步说明。
例:The news that they had won the game soon spread over the whole school.他们比赛获胜的消息很快传遍了整个学校。
析:they had won the game说明The news的全部内容,因此该句为同位语从句。
二、正确运用同位语从句的引导词,准确把握同位语从句
1.如同位语从句意义完整,应用that引导同位语从句。(即that 不充当任何成分,只起连接作用,不可省略)
例:The general gave the order that the soldiers should cross the river at once.将军下达了战士们立即过河的命令。
析:the soldiers should cross the river at once是the order的全部内容,且意义完整,因此应用that引导同位语从句。
2.如同位语从句意义不完整,需增加"是否"的含义,应用whether引导同位语从句。(if不能引导同位语从句)
例:We'll discuss the problem whether the sports meeting will be held on time.我们将讨论运动会是否会如期举行的问题。
析:the sports meeting will be held on time意义不完整,应加"是否"的含义才能表达the problem的全部内容,因此应用whether引导同位语从句。
