题目
She tells me __my pictures are good or not
a weather b that c if d unless
答案是a但是这种形式不能用if吧.
答案
答案:A
解析:whether 和if 的用法:当句 子有 or not 时只能用 whether,参考下面的 1
整句翻译:她告诉我我的图片是否好
whether和if都可以引导宾语从句,表示"是否",在口语或间接引语中两者可以互换使用.如:
I wonder if / whether I can get some advice from you.
Ask him whether / if he can come.
但在有些情况下,whether和if的用法有一定区别.
1.whether引导的从句常可以与连词or或or not直接连用,而if一般不能.如:
正:Let me know whether you can come or not.
误:Let me know if you can come or not.
2.当宾语从句提到句首时,只能用whether引导,而不能用if.如:
正:Whether it is true or not,I can't tell.
误:If it is true or not,I can't tell.
3.whether可以引导带to的不定式,if则不能.如:
正:I don't know whether to accept or refuse.
误:I don't know if to accept or refuse.
4.whether及其引导的成分可放于介词之后,作介词的宾语,但if不能.如:
正:I worry about whether I hurt her feelings.
误:I worry about if I hurt her feelings.
5.whether可以引导从句,作主语、表语或同位语,而if不能.如:
正:It was uncertain whether he would come.
误:It was uncertain if he would come.
