The government spends money protecting endangered animals

A. a number of

B. many

C. large numbers of

D. plenty of

答案：

A. a number of

B. many

C. large numbers of

D. plenty of

解析：考查数词。A number of 许多修饰可数名词复数；many许多;larger numbers of 许多；plenty of 许多修饰可数或不可数；句意：政府花了很多的钱保护濒临灭绝的动物。只有plenty of 可以修饰不可数名词，所以选D项。
