题目内容
11．The living conditions in my hometown haveimproved （改善）a lot in the last few years．分析 在过去的几年里，我家乡的居住条件已经改善了很多．
解答 答案：improved 根据时间状语in the last few years及助动词have，可知本句是现在完成时的句子．其构成为have/has+动词的过去分词．此空前已经有have，故此空需要动词的过去分词形式．根据所给汉语提示"改善"，可知其动词形式为improve，其过去分词形式为improved．故答案为improved
点评 本题考查动词的过去分词．have后如果紧接着出现动词，就要考虑have+done（现在完成时）．
