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。
2. 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。
3. It作形式主语,that引导真正的主语从句。
4. 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。
2. 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.
3. 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。
4. 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。
2. That is why+结果,表示“那就是.....的原因”。
3. That is because+原因,表示“那是因为......”。
4. 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。
