when and where should we go () not been decided.

问题描述:

when and where should we go () not been decided.
如上,这个句子()的部分填“has”还是“have”
when and where to go has not been decided.
这个句子是因为不定式做主语所以谓语动词用单数.但是我总是想下意识地填 have,因为总觉得现在是两个不定式做主语了.
但同时,语感又会促使我选has.
好矛盾.

这题应该用has
when and where we should go 其实表达的是一个意义整体,用单数
如果写成
when we should go and where we should go ...,把两层意思分开,就要考虑用have了.
