2019年mpa考试英语真题——虚拟语气351

{01}---Sorry. I must be off.
---How nice it would be if you_____a bit longer! A.stay B.would stay C.stayed D.have stayed 解析： 由句中的“would be”可知, 这是一个与现在事实相反的虚拟语气, 从句要用一般过去式stayed, 故答案为C。
本题选C。
{02}Tom, you _____ leave all your clothes on the floor like this!
A.wouldn’t B.mustn’t C.needn’t D.may not 解析：本句是一个主从复合句，主句含有情态动词can，动作go还未发生，属于将来时；因此，when引导的时间状语从句要用现在时；当go动作发生时，finish动作已经完成了，故选 C。当然，空格出还可以用finish。如：
She will go to bed when she has done/ finishes her homework.
You can go to play football if you have finished your work.
本题选C。
