we know that the highway was full () kinds of traffic ()the radio
问题描述：
we know that the highway was full () kinds of traffic ()the radio
A of by.B with by.C of on.D.with on
答
C
两个搭配
第一个是be full of
第二个是,on the radio为什么by不对典型的中式英语
这个介词，一般固定搭配比较多，有的是没有语法道理可讲的
比如，on the radio,在收音机里，就不能用in the radio
从字典里找，就只能是in the dictionary,而不能是from the dictory
