Question

There are _______ sharing bikes in many cities. So there will be _______ pollution.

A. less and less; more and more    B. less and less; fewer and fewer

C. more and more; less and less    D. fewer and fewer; less and less

Answer

C

【解析】许多城市都有越来越多的共享自行车。所以会有越来越少的污染。“比较级+比较级”表示“越来越…”，“more and more”指“越来越多的”，“less and less”为“越来越少的”，该短语用来修饰不可数名词，pollution是不可数名词，所以该短语可用。Fewer and fewer意为“越来越少的”，但用来修饰可数名词复数，本题不能使用，故选C。
