第二讲　名词性从句 　　名词性从句包括主语从句、表语从句、宾语从句和同位语从句。 考点一　名词性从句的引导词 　　名词性从句由不同的引导词引导，从句一般保持陈述语序。 引导名词性从句的连接词可分为3类： 1.that引导的名词性从句 that只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。该从句作主语通常用it作形式主语，而将从句置于句末。 ①Scientists have obtained more evidence that plastic is finding its way into the human body．(同位语从句) ②It is suggested that we should limit the amount of cars to improve our environment．(主语从句) 2.wh-引导的名词性从句 wh-包括who， whom， whose， whoever， what， 学生用书⬇第274页 whatever， which， whichever等连接代词和where， when， why等连接副词。wh-词既起连接作用，还可充当主语、宾语和表语等。从句作主语也常用it作形式主语，而将wh-从句置于句末。 It remains to be seen how these obstacles will help

been looking forward to for years． (2)wh-ever既可引导名词性从句，又可引导让步状语从句；而no matter wh-只能引导让步状语从句。 The gold medal will be awarded to whoever (anyone who) wins the first place in the bicycle race． No one is allowed to break the regulations，whoever (anyone who) he is． 3.if， whether引导的名词性从句 (1)引导主语从句、表语从句、同位语从句时一般用whether， 不用if。 The question is whether technology is going to be our servant or our master． (2)whether与if引导宾语从句时大多数情况下可以互换， 但下列情况只能用whether： ①后面直接跟or not时用whether They now have two weeks to decide whether or not to buy． ②用于介词后引导宾语从句时用whether But if he’s out there every day and playing hard，
