题目内容
9.My father started to work in the factory when he was 17years old.He ________ for 30years in it.( )| A. | has worked | B. | worked | C. | works | D. | will work |
分析 我爸爸在他17岁的时候就开始在这个工厂工作,他已经在里面工作了30年了.
解答 答案:A.
现在完成时的构成:have/has+过去分词,表示过去发生的动作对现在造成的影响或结果或表示过去的动作或状态持续到现在,经常和"for+段时间"状语连用.根据时间状语"when he was 17years old"以及"for 30years in it"可知"工作"这个动作从过去开始一直延续到现在,还有可能延续下去,所以要用现在完成时,故选A.
点评 首先要掌握现在完成时的构成以及用法,然后结合具体的题目,就可以确定正确答案.
