15．在过去的几年里我的生活发生了很大的变化．My life has changed a lot in the last/past few years．分析 My life has changed a lot in the last/past few years
解答 答案：My life has changed a lot in the last/past few years．
根据中文含义在过去的几年里我的生活发生了很大的变化，判断出本句的时态是现在完成时，它的构成是have/has+过去分词，主语是my life我的生活，是不可数名词，故用has，改变change的过去分词是changed，变化大用a lot 表示程度，在过去的几年里是时间状语in the last/past few years，故答案是My life has changed a lot in the last/past few years
点评 我们首先判断出时态，然后再根据语法得出答案．
