I have no idea whether he has sisters, and if he does, _____? [ ] A. how many sisters does he have

I have no idea whether he has sisters, and if he does, _____? [ ] A. how many sisters does he have B. he has how many sisters C. how many he has sisters D. how many sisters he has

正确答案是 D. how many sisters he has

详细解释:

这是一个间接疑问句
题目前半部分是一个陈述句(I have no idea ...),后面的疑问部分应以间接疑问的语序,即:疑问词 + 主语 + 谓语

比较各个选项:

A:how many sisters does he have
这是直接疑问句的语序(疑问词 + 助动词 + 主语 + 动词),不能用在已知的陈述句之后,除非前面有逗号并且是引述的直接问句。
❌ 不正确。

B:he has how many sisters
语序完全是混乱的,不符合英语疑问句结构(即使是间接疑问句也要把疑问词提前)。
❌ 不正确。

C:how many he has sisters
顺序错误,how many 后面要紧接名词(sisters),然后才是主语 + 动词,不可把 sisters 放在最后。
❌ 不正确。

D:how many sisters he has
符合间接疑问语序:疑问词(how many)+ 名词(sisters)+ 主语(he)+ 谓语(has)。
✅ 正确。
