Question

More attention must be paid         the endangered animals..

A．protect

B．to protect

C．to protecting

D．protecting

Answer 1

C

试题分析：考查短语pay attention to的用法。pay attention to中to为介词，后面要接动名词，故选答案C。本题是一个被动句，为了更容易看出考点，可以先还原成主动句：we must pay more attention         the endangered animals.这样很容易看出是考pay attention to的用法。
点评：短语中to为介词的还有：be / get / become used to 习惯于 be given to 喜欢;癖好 be related to 与…有关系 be addicted to 沉溺于;对…上瘾 be opposed to 反对 devote oneself to 献身于;专心于等等。
