问题描述:

they would not allow him___across the enemy life
a.to risk going
b.risk to go
c.risking to go
d.risk going
首先risk
其次,但是allow的搭配的不是只有allow sb to do和 allow sb doing吗?怎么有个allow sb to doing了呢?

答案是A,但是后面不是allow sb to doing 而是allow sb to do ,risk +doing 是固定用法,表示冒什么的风险.这句话的意思是他们不允许他冒险过一辈子的仇恨生活.没有risk go 用法,只有risk +doing 这种用法
