There's enough bird food here ___ for two months.
There's enough bird food here ___ for two months.
A.to last B.lasted C.lasts D.has lasted
这个选什么,为什么呢 我觉得是A

There's enough bird food here ___ for two months.There's enough bird food here ___ for two months.A.to last B.lasted C.lasts D.has lasted这个选什么,为什么呢 我觉得是A
首先排除b过去式和d现在完成时
to do 表示目的,所以选A
这里有足够多的鸟食来维持2个月.
真正的be动词是is,所以谓语动词lasts就不可能出现啦.一个句子中不会有两个谓语

我也觉得是A

选c

应该是C，因为有个here在前面，而here后面不能跟To,根据语态，There's，故选择C

选A。这里的here可以省略掉不看，就是There's enough bird food to last two months. 有足够的食物可以持续两个月。to do 表示将要发生的事。

选A 本题意为有足够的鸟食来维持2个月!to do表将来,所以选A

A
