whether的用法

如题所述

conj.
1. (引导名词从句)是否
Ask him whether he can come or not.
问问他是否能来。
I don't know whether you like flowers, sir.   
先生,我不知道您是否喜欢花。
2. (与or连用,引导状语从句)不管是......(或是)   
We'll go on with the work, whether we can find the necessary tools or not.   
不管我们能否找到所需的工具,我们要把这件工作做下去。   
在引导定语从句时,一般情况下whether和if都可使用,但whether的适用范围要比if广,实在不知道应用什么的时候,选whether。   
例如从句若出现了选择项:A or B,只能用whether而不能用if   但要注意,从句为否定句是,只能用if,而不能用whether   

pron.
1. 【古】(两个中的)哪一个,任一个   
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.   
正: His first question was whether Tom had arrived yet.   
误: His first question was if Tom had arrived yet.   
正: We must consider the question whether we will take these measures.   
误: We must consider the question if we will take these measures
