a day or two,one or two days 后面的动词分别用单数还是复数?

因为都表示一段时间，它们做主语的时候谓语都要用单数。
比如：one or two days is not enough for this mission.

不知道你是什么意思..我只听说:in a day or two 和in one or two days ,,2个意思一样,指在一两天内..都是和in一起组成短语..只会做宾语或者宾补,,怎么会说后面的动词用单数还是复数?....举个例子,He will be back in a day or two(one or two days ).他将在一两天内回来....也许你见到是这种类型,in a day or two he will be back .也是一样的,都是he做主语,,只是倒装句而已.......希望回答的是针对型的

什么样都情况下这两个词组会做主语呢？
但是要做应该都用复数
