Answer 1

1. It is desired that she was promoted to the position of the manager.
改成：It is desired that she (should) be promoted to the position of the manager.

2. I wish that they didn't leave so early that day.
改成：I wish that they hadn't left so early that day.

3. I could buy the ten-speed bicycle myself, but my mother promised to give it to me on my birthday.
改成：I could have bought the ten-speed bicycle myself, but my mother promised to give it to me on my birthday.
解释：根据题意应该用虚拟语气：could have done sth（本可以做某事，实际上未做）

改成：I would rather that Miss Evans had taught us English literature last semester.
解释：would rather引导的宾语从句采用虚拟语气，对过去的虚拟从句采用过去完成时。

5. "Don't you think it is time you work harder at your lessons?"the mother said to Tom.
改成："Don't you think it is time you worked harder at your lessons?" the mother said to Tom.
或："Don't you think it is time you should work harder at your lessons?" the mother said to Tom.
