题目内容
14.This drug is less likely to cause side effects when ________ late in the day.( )A. | taking | B. | taken | C. | to take | D. | takes |
分析 句意:这种药在每天晚些时候服用,更不会产生副作用.
解答 答案B.分析句子成分可知,主句主语"the drug"与所给动词"take"构成逻辑上的被动关系,因此用过去分词,从而排除A、C和D项.句中"when ________ late in the day"为省略结构,完整结构为"when this drug is taken late in the day",在句中作时间状语,因此B项符合语境,故选B.
点评 本题考查现在分词作状语.做这类题目首先根据句意判断是谓语还是非谓语,如果是分词做状语的时候,看动词与逻辑主语构成主动关系,就使用现在分词的形式;如果二者构成被动关系就使用过去分词的形式.不定式表示动作未发生作目的状语.
