it is not always possible to foresee the obstacles ____ your way towards an ambitious goal.

题目

it is not always possible to foresee the obstacles ____ your way towards an ambitious goal.
A.blocked
B.blocking
C.to block
D.to blocking
为什么选b,专业的来,说废话的别回了,做错的就更别套答案了.

答案

首先排除D,这是个介词短语, 没这个搭配

your way 是后面非谓语动词的宾语, 可见得用主动式,这样可以首先排除A(表被动的过去分词）

blocking your way towards an ambitious goal 是现在分词短语做后置定语修饰the obstacles

the obstacles blocking your way towards an ambitious goal 阻碍你朝着雄伟目标前进的障碍
=the obstacles which block your way towards an ambitious goal
