Question

【题目】 When _______ this medicine, it is a good idea to avoid_______ alcohol.

A. taking; drinking B. taken; drinking

C. taking; to drink D. taken; to drink

Answer 1

【答案】A

【解析】

试题分析：avoid sth./ doing sth.避免做某事，avoid后跟名词或动名词，所以第二个空要用动名词drinking，C项和D项排除；本题隐含的主语是“人们”，与动词take之间是主谓关系，要用现在分词taking，故选A。
