同学你好，该知识点来自沪江网校《新概念英语3、4册连读【随到随学班】》的课程，想要更系统的学习，欢迎进入课程学习。不仅可以和更多的同学一起学习，而且还有老师、助教随时的学习指导和知识点解答哦。

同学你好~
haven't made是现在完成时。

现在完成时：have/has+过去分词

过去完成时：had+过去分词

动词wish后接宾语从句时，从句谓语要用虚拟语气。若要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词；若表示将来没有把握或不太可能实现的愿望，用would (could)＋动词原形。如：

I wish I were not so busy. 但愿我不那样忙碌。

I wish I were [was] better looking. 要是我长得漂亮些就好了。

She wished she had stayed at home. 她后悔的是她当时要是留在家里就好了。

I wish you would go with us tomorrow. 要是你明天同我们一起去就好了。

I wish you wouldn’t look down on this kind of work. 我希望你不要看不起这种工作。

This watch has gone wrong. I wish I had bought a better make. 这只表坏了，我真愿意我买的是好一点的牌子。

祝同学学习进步~
