【正确答案】:
THERE ARE FEWER AND FEWER TIGERS,/TIGERS ARE DECREASING IN NUMBER, ALMOST ON THE VERGE OF EXTINCTION; ON THE OTHER HAND, THERE ARE MORE AND MORE CATS AND THEY HAVE BECOME PETS.
【题目解析】:原译文对“越来越多、越来越少”的翻译不正确。“越来越少”可用decreasing in number或fewer and fewer表达,“越来越多”可用increasing in number或more and more表达。
