题目

4.It is _____ knowledge that the traffic situation in the city requires improving
A general B usual C ordinary D common
答案好像是D,我想问C能不能选啊,有时候不是可以互换的吗
6 .Running in the rain ,__________
A l fell in a stone
B a stone blocked me
C a stone caused me to fall
D l was fallen on a stone
我想问一下为什么不选D,根据中文的翻译,不应该是被石头绊倒吗?

答案

ordinary 强调 平常的,普通的,不特殊的
common 强调 范围广,共同的
第一题是主语从句,
that the traffic situation in the city requires improving 是众所周知的
第二题 考察状语从句的省略 ,
当状语从句的主语和主句主语相同时,从句的主语可省略.
running的主语是 I ,stone 不能running ,排除 B C
A D 区别是 主动或 被动 ,I 和 fell 是主动,所以选A
