疑问词加to do是什么语法(疑问词todo)(1)

When and where to build the new factory ______ yet.

A: is not decided

B: are not decided

C: has not decided

D: have not decided

题中有yet干扰,易选C。

解析:“疑问词 to do sth.”作主语,谓语动词用单数形式,与不定式短语作主语,谓语动词也用单数形式相同。由此可以排除B D; decide 与 when and where to …存在着逻辑上的动宾关系,表被动,故应使用被动语态,因此该题正确答案为A. 如果C项为has not been decided 则也正确。答:选A
