Question

There are _______ bears on the earth because they have _______ space on it.

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

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

Answer

A

【解析】句意：地球上熊越来越少，因为在地球上，它们的生存空间越来越少。“比较级+and+比较级”表示“越来越⋅⋅⋅⋅⋅⋅”。fewer是few的比较级，fewer and fewer 越来越少；less是little的比较级，less and less越来越少；more是many、much的比较级，more and more 越来越多。B,D答案不符合逻辑，要排除。few修饰可数名词复数，less修饰不可数名词；bears为可数名词复数，space为不可数名词。故选A。
