【正确答案】 C

【答案解析】[解析] 句意：要是中学时我好好学习，就能进入大学学习了。本句考查的是虚拟语气在if引导的状语从句中的应用。当if引导的从句中含有were，had，should，would等词时，可以省略if，把这些词放在主语之前。本句表示与过去事实相反的假设，因此选C。相当于：If I had studied hard in high school, I could have gone to university to study.又如：Should I go there, I would tell you.如果我去，我就告诉你。Were I you, I would not give up.如果我是你，我就不放弃。
