问题描述:

英语题where and when to go _(not decide)yet.maybe we need to have another discussin
能用haven't decided吗 还有能说明原因吗

在下认为不可
when and where to go 是主语从句,是一个从句,单数
同时,是被决定,被动
在下认为应用hasn't been decided

可以

不能,应该用hasn't been decided
因为这里涉及到一个谓语动词的单复数形式,因为“where and when to go ”表示一个单数概念 ,而且表示被动

hasn't been decided 被动语态。“ 何时何地去”作主语, 动词用单数。
