问题描述:

We were delayed by ( ). 1.a heavy traffic 2.heavy traffic 3.some heavy traffic 4.traffic being heavy
正确答案选择3.这题我看不懂.为什么选择3呢?

本来更习惯的用法是 by the heavy traffic,可惜2中没有the,只好用3这个别扭的用法,但语法是对的。

some除了表示某些,还有表示某个的含义。

对的
heavy traffic 为不可数,可排除1并确定3
这个要加冠词的话,应该是 the heavy traffic 或者the traffic being heavy (动名词的复合结构),因为是特指这一次
选3
