16.This drug is less likely to cause side effects when ______ late in the day.( )A. | taken | B. | taking | C. | to take | D. | being taken |
分析 这种药在白天晚些时候服用的时候产生副作用的可能性要小些.
解答 答案:A
解析:后面的句子完整的形式为:when it is taken late in the day(因为"药"与"服用"时间是被动关系,所以要用被动语态).此处是省略了从句的主语it及be动词(is),而直接使用动词的过分词形式作时间状语.
点评 本题考查过去分词,做此类题目一定要仔细分析句子结构并根据句意找出所缺的成分,再分析各个选项的含义及用法,选出最终答案.
