yet 是否一定要用完成时?
When and where to build the new factory * yet .
A has not decided B is not decided
答案肯定是B ,不过好象应该是has not decided 吧?
啊,我自己都打错了,惭愧 ,想写的是has not been decided

A肯定是错的,这个句子明显改用被动语态

is not decided,也就是B选项,可以选但是不标准。准确的应该是has not been decided

yet一般来说就是跟完成时。只有一种情况例外,就是表达但是的意思,比如
Yet she did it anyways even though I told her not to 尽管我告诉她不要这么做,她还是做了

yet可以不跟完成时连用
此句A选项应改为被动has not been decided就可以选了

不一定,A选项无被动形式
