同位语从句讲与练一定义:用作同位语的从句叫做同位语从句。
二用法:同位语从句的先行词多为fact, news, idea, thought, word, question, reply, report, 等They were all very much worried over the fact that you were sick.Where did you get the idea that I could not come?Early in the day came the news that Germany had declared war on Russia. 三引导词:由连词that ; (whether)引导;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)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。
