whether与if用法区别1.宾语从句是否定句时,只用if,不用whether.

e.g.I wonder if it doesn’t rain.

2.用if 会引起误解,就要用whether.

e.g.Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解)

3.习惯上宾语从句中的whether 与or not直接连用,就不能换

成if;不直接连用时,即构成whether ...or not的结构时,英语中只用whether;而美语中常用if.所以我们的教学中习惯上采用whether...or not的说法.

e.g.I don’t know whether or not the report is true.

I don’t know whether the report is true or not.

4.介词后的宾语从句要用whether引导.

e.g.It depends on whether we have enough time.

5.whether 可与不定式连用,而if不与不定式直接连用.

e.g.They don’t know whether to go there.

6.whether 也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if.

注意：引导主语从句时,习惯上whether从句置于句首时,whether不能换用if,如：

Whether you’ll gain knowledge successfully or not depends on how hard you will work.

你能否真正学到知识,就看你努力的程度如何.

但当采用形式主语It 将主语从句后置时,用Whether 和if 均可,如:

It’s not clear to me whether /if she likes the present.

7.引导条件从句时,只能用if,而不能用whether.

e.g.Please come to see me if you have time.
