heavy traffic還是crowded traffic

漢語說“交通擁擠”，說成英語是heavy traffic，還是crowded traffic? 請看題：

“Why couldn’t they meet us at five o’clock?” “Because they were delayed by ________.”

A. heavy traffic               　                        B. heavy traffics

C. crowded traffic                                      D. crowded traffics

【陷阱】B、C、D三項均容易誤選。

【分析】對于此題，首先要明確traffic為不可數(shù)名詞，沒有復(fù)數(shù)形式，故排除B和D。另外，漢語習慣說“交通擁擠”，而英語習慣上卻不能用crowded 來修飾 traffic，要表示漢語的“交通擁擠”，英語通常說heavy traffic，即選A。如下面一題也是選A：

She is not a competent driver and can’t cope with driving in _______.

A. heavy traffic               　                        B. heavy traffics

C. crowded traffic                                      D. crowded traffics
