题目内容
19.Don't worry.The drug,if taken according to the directions,will have no side effect.(take)别担心,如果按照说明服用,这药不会有任何副作用.
分析 别担心,如果按照说明服用,这药不会有任何副作用.
解答 答案:if taken
在时间、条件、让步、方式等状语从句中,当从句的主语和主句的主语一致时(或者从句中含有主语it时),且从句中含有系动词be,此时从句的主语和be动词通常可以一同省略,本句中的完整形式应该是if it is taken according to the directions,由此可知答案为if taken.
点评 熟悉状语从句中省略的基本条件,正确确定答案.
