1. I wish it would stop raining.(虚拟动词would+动词原形stop)　

我希望雨能停止。(事实上雨还在下着呢)　

5. They will wish they had listened to us sooner.　

(will wish ,had + listened)(事实上并不如此)　

例题分析：I wish I ______ longer this morning, but I had to get up and come to class.　

A. could have slept

B. slept　

C. might have slept

D. have slept　

动词wish后面接从句，表达不可能实现或与事实相反的情况时，谓语动词要用虚拟语气，即用过去式(表示现在发生的动作)或过去完成式(表示过去发生的动作)。本题后半句谓语动词have用的是过去时had to get up and come, 所以前面要用过去完成时表示过去发生的动作。所以, 选项A)could have slept是答案　

三)、对将来情况的虚拟(表示将来的主观愿望)：　

从句动词"would/should/could/might + 动词原形"(时间上较后)(请注意：主句和从句的主语不相同)。用wish表示对将来事情的愿望。例：　

4. I wish you had called earlier.　

(wish, had + called)(事实上已迟了)　

3. We wished he had spoken to us.　

(wished，had + spoken)(事实上他并没同我们讲)　

2. He wishes he hadn’t lost the chance.　

他真希望没有失去机会。(其实已失去)　

1. I wish (that可省略，下同)I hadn’t wasted so much time.　

我后悔不该浪费这么多时间。(事实上已浪费了)　

6. When we begin the trip, they will wish they were with us.(will wish,过去虚拟动词were)(事实上并不和我们在一起)　

二)、对过去情况的虚拟(和过去的事实相反)：　

用wish表示对过去事情的遗憾。其句子结构为：宾语从句的谓语用过去完成时，或would, could, might+现在完成时。例：　

5. Now that he is in China, he wishes he understood Chinese.(wishes,过去虚拟动词understood)　

现在他在中国，他希望能懂得中文。(事实上并不懂)　

4. When she was at the party, she wished she were at home.(wished,过去虚拟动词were)(事实上并不在家)

3. I wish I were a bird.(wish, were)但愿我是只小鸟。(事实上不可能)
