从句用陈述句语序.A是疑问句

(从句中含有or,强调选择,这里只宜用whether)

3) 只用whether的情况

例 1 He asked whether I wanted to go by air or by sea.

他问我是想坐飞机还是坐船去。

(从句中含有or,强调选择,这里只宜用whether)

例 2 He asked whether or not I wanted to insure my luggage.

他问我是否想给行李保险。

(只有whether后面可以直接跟 or not)

例 3 Bill asked whether, if I got the job, I’d move to New York.

比尔问我如果找到工作,是否要搬到纽约去。

D. I don't think + 陈述句 whether...or not 固定搭配

d if 后不用not,whether后从句陈述句语序

很简单,wherther用于笔头,if用于口语
