题目内容
4.I am a teacher and I _____ in this school for 5years.( )| A. | teach | B. | taught | C. | will teach | D. | have taught |
分析 我是一位老师,我在这个学校已经教了5年了.
解答 答案:D.
现在完成时基本用法之一:表示过去已经开始,持续到现在,而且还可能继续下去的动作或状态,常与since或for引导的时间状语连用.根据 for 5years!可知本句应该用现在完成时态.现在完成时态的构成:助动词have/has+过去分词,根据主语I,所以应该用have.时间状语是for 引导的一段时间,所以动词必须是延续性的.故选:D.
点评 本题主要考查动词时态,做此类题目要注意时间状语,注意句子所表达的含义,才能更好地判断.同时更应记清时态的构成形式.就本题而言,主要考查现在完成时态.同时应该注意动词的辨析.
