问题描述:

You should take off your shoes before __ someone's home in Japan.
A.enter B.enter into C.entering D.intering into
为什么?

C状语从句中如果主从句的主语是同一人或物时,连词后是主语加be动词加分词时,从句主语可以省略直接用分词。enter是及物动词后直接加地点所以选C

C
介词后面要用ing形式,enter into 是重复词组,不存在。所以选c

选c
首先before是介词,后接动词ing
然后enter已有进入的意思,不能加into

D
介词后面跟动名词
