题目

—What would you wish to do if you were a college student again?    —That's very hard to say, but I wish I when I was a college student. A. has not studied biology          B. did study biology C. had studied biology              D. studied biology 答案：C 解析: 本题考查wish后接宾词从句的用法。Wish后接宾词从句，从句的谓语动词要用虚拟语气，因为题干提示与过去事实相反，故用had done。写出下边句子中加粗词的反义词。 列车正在倒退。（　　）
