【易错点提醒四】同位语从句与定语从句易混易错点
03 易错题通关
易错陷阱1：主语从句连接词what/that/whether/if易混易错点。
【分析】 1.that引导主语从句时，无词义，只起连接作用，一般不能省略。what在从句中作主语、宾语、表语和定语。
whether引导的主语从句可放在句首，if引导主语从句在句尾，且用it作形式主语。
It作形式主语，that引导真正的主语从句。
What引导主语从句时，谓语动词一般用复数形式，若表语是复数，则谓语用复数。
易错陷阱2：宾语从句引导词及介词后接宾语从句易混易错点。
【分析】1.doubt用于肯定句时，宾语从句用whether，doubt用于否定句时，宾语从句用that引导。
介词后跟宾语从句时只能用wh-类连接词引导；如：I’m surprised at what he said.
介词后如果跟that从句，要先加it作形式宾语，再加that从句。
如：depend on it that...; rely on it that...; see to it that...等。
宾语从句的时态：主句是现在时或将来时，从句用句意的各种时态。主句是过去时， 从句用相应的过去时态。 从句表示客观事实或真理，从句都用现在时。
易错陷阱3：表语从句引导词及三个句式易混易错点。
【分析】1. as if/as though 引导时，从句可用陈述语气，也可以用虚拟语气。
That is why+结果，表示“那就是.....的原因”。
That is because+原因，表示“那是因为......”。
The reason why/for... is that ..., 表示“......的原因是......”。
易错陷阱4：同位语从句与定语从句易混易错点。
【分析】that引导同位语从句时，在从句中不作句子成分；that引导定语从句时，在定语从句中作主语或宾语。同位语经常修饰的名词有：fact, idea, news, promise, information, message, belief, opinion, possibility, thought, wish, truth, question, problem, reply, answer, report, suggestion, advice, order, warning等。
【易错点提醒一】 主语从句引导词what/that/whether/if易混易错点
