功能例词从属 连词只起连接作用,不充当从句中的任何成分。that, whether连接 代词既起连接作用,又在从句中担任成分(主语、宾语、表语或定语)。who, what ,whose, which连接 副词既起连接作用,又在从句中担任成分(状语)。when, where, why, how复合代词 & 复合副词既起连接作用,又在从句中担任成分(主语、宾语、表语或定语、状语)。whoever, whatever, whichever, whenever, wherever, however
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。
3、如同位语从句意义不完整,需增加"什么时候"、"什么地点"、"什么方式"等含义,应用when, where, how等词引导同位语从句。
例1:I have no idea when he will be back.
析:he will be back意义不完整,应加"什么时候"的含义才能表达idea的全部内容,因此应用when引导同位语从句。
例2:I have no impression how he went home, perhaps by bike.
析:he went home意义不完整,应加"如何"的含义才能表达impression的全部内容,因此应用how引导同位语从句。
4、当主句的谓语较短,而同位语从句较长时,同位语从句常后置。
如:The thought came to him that maybe the enemy had fled the city.
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。
