it is impossible( )before lunch.A.of us to get there.B.for us get there.C.to you to get there.
D.you to get there.选择正确的,为什么?
不好意思，B选项确实是for us to get there.

B for us to get there “对我们来说午餐前到达那里是不可能的.”因为 it is +adj.+for sb +to do sth 固定句型‘对某人来说做……是…….’动词不定式作真正的主语,IT 作形式主语）

答案：for us to get there

B选项是不是少了个to ?
for us to get there

for us to get there
