语法
关于if引导的条件状语从句与宾语从句
当if表示“如果”,引导条件状语从句时
1)当谈及可能发生的行为动作,以及其可能产生的结果时,就要用“主将从现”
Eg:
If(itis)possible,I’llmeetyouattherailwabystation.
2)当表示客观事实、结果时,主句和从句都用一般现在时。
Ifyouheatice,itturnsintowater.
3)当if引导的条件状语从句时,主句可以使用祈使句,或情态动词(如can,should,may,must等)来代替一般将来时
Eg:
Ifyouwanttoloseweight,youshouldtakemoreexercise.
=Takemoreexerciseifyouwanttoloseweight.
当if表示“是否”,引导宾语从句时
1)当主句是一般现在时,从句根据实际情况用相应的时态
Iwonderifyouwillattendthemeetingtomorrow.
2)当主句是一般过去时,从句应用过去相应的时态
Iwonderedifyouwouldattendthemeetingthenext/followingday.
3)当从句是客观真理时,从句永远用一般现在时
Eg:
Mymothertoldmethaticeturnsintowaterifyouheatit.
用whether而不用if表示“是否”,引导宾语从句的情况
当宾语从句中出现“ornot”时
Idon’tknowwhetherornotIshouldaskhimaboutit.
