The bridge is too long for us to _______一个选择题

问题描述:

The bridge is too long for us to _______一个选择题
The bridge is too long for us to _______.
A across
B across it
C cross
D cross it

选C
根据“to+动词原形”,而across是介词,所以先排除A,B
另外,cross的逻辑宾语其实就是句子的主语“the bridge”,所以不能再加it
我们可以把这个句子改成:It's too long for us to cross the bridge.这样应该看清楚了吧.
