题目内容
18．If you______at school，you______a college student now．（ ）| A． | had studied hard； would have been | |
| B． | should have studied hard； should have been | |
| C． | had studied hard； would be | |
| D． | would study hard； must have been |
分析 如果你在校期间认真学习的话，你现在已经是名大学生了．
解答 答案：C．
根据题干中a college student now"现在的大学生"可知，从句中的at school"在校期间"应是一个过去的时间，即从句与过去事实相反，主句与现在事实相反．所以if从句中的谓语动词形式为过去完成式had done，主句谓语动词形式为would/could/might/should do．故选C．
点评 此题考查混合虚拟条件句．混合虚拟条件句指主句与从句的动作发生在不同的时间，这时主从句谓语动词的虚拟语气形式因时间不同而不同．解题时需在掌握if虚拟条件句用法的基础之上，再根据主从句的时间状语或语境提示来确定谓语动词的形式．
