易错总结
1.状语从句的时态
主将 从现 在时间状语从句或条件状语从句中,主句用一般将来时,从句用一般现在时表示一般将来时
过去 时态 在since引导的时间状语从句中,从句常用一般过去时,主句常用现在完成时或一般现在时,如“It is/has been+时间段+since+一般过去时”
主现 从现 若主句是祈使句或主句中有情态动词,那么从句常用一般现在时表示一般将来时
2.辨析if和when引导的宾语从句和状语从句
从词义 来判断 if作宾语从句的连接词时,相当于whether,词义为“是否”;if引导条件状语从句时,词义为“如果”
when作宾语从句的连接词时,词义为“什么时候”;when引导时间状语从句时,词义为“在……的时候”
从时态 来判断 if和when引导宾语从句时,宾语从句中的谓语动词的时态应根据主句的谓语动词的时态作相应的变化
if和when引导条件状语从句或时间状语从句时,若主句中的谓语动词用了一般将来时,则从句中的谓语动词通常用一般现在时表示将来
