Question

若whether和if同时出现在一个句子中，是否if优先？

同一个单项选择题中，答案中同时出现了if和whther，并且没有or not,是不是就选if?
题目：It depends on___he has money. A.if B.weather. C.if or not. D.whether. 我们老师说选 "D" ,可我觉得应该选"A",麻烦大家看一下，谢谢！

Answer 1

题目是什么？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.
