When and where to build the new factory ____ yet.
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
看到yet要考虑完成时吗?
答
A. is not decided， 根据最靠近谓语的主语选择is
如果是C和D则需要加been
答
选a
c选项如果改成被动语态就对了
答
A
前面是疑问词+不定式结构作主语,谓语动词用第三人称单数,yet一般与现在完成时态连用,但是这里的C答案要改成：has not been decided要用被动语态.
