您好,現在冰冰來為大家解答以上的問題。if和whether的區(qū)別和用法例句,if和whether的區(qū)別相信很多小伙伴還不知道,現在讓我們一起來看看吧!
1、whether和if都可以引導賓語從句,表示“是否”,在口語或間接引語中兩者可以互換使用。
2、如: I wonder if / whether I can get some advice from you. Ask him whether / if he can come. 但在有些情況下,whether和if的用法有一定區(qū)別。
3、 1. whether引導的從句??梢耘c連詞or或or not直接連用,而if一般不能。
4、如: 正: Let me know whether you can come or not. 誤: Let me know if you can come or not. 2. 當賓語從句提到句首時,只能用whether引導,而不能用if。
5、如: 正: Whether it is true or not, I can’t tell. 誤: If it is true or not, I can’t tell. 3. whether可以引導帶to的不定式,if則不能。
6、如: 正: I don’t know whether to accept or refuse. 誤: I don’t know if to accept or refuse. 4. whether及其引導的成分可放于介詞之后,作介詞的賓語,但if不能。
7、如: 正: I worry about whether I hurt her feelings. 誤: I worry about if I hurt her feelings. 5. whether可以引導從句,作主語、表語或同位語,而if不能。
8、如: 正: It was uncertain whether he would come. 誤: It was uncertain if he would come. 正: His first question was whether Tom had arrived yet. 誤: His first question was if Tom had arrived yet. 正: We must consider the question whether we will take these measures. 誤: We must consider the question if we will take these measures.。
