大一英语简单语法问题

Question

1.虚拟语气有哪些表达形式？有哪些表达时态？
2.i wish you had come to cinema with us last night.
为什么其中是had 而不是have?
3.wish 后面一定是虚拟语气吗？wish还有没有其它用法？

Answer 1

if从句 主句
假设过去： had done “4”＋have done
假设现在： did（were） “4”＋do
假设将来： did（were）/ ↘
were to do/ →“4”＋do
should do ↗
（“4”表示would/could/should/might选其一）

假设过去例句：If you not been late,you would
have heard what he told us.

假设现在例句：If i were you ,i could make the

decision.

假设将来例句：If i had time tomorrow,i would

help him.
—————————————————————
特殊情况：①省略的虚拟条件句
如：If i were you,i would think it twice.
省略：Were i you,i would think it twice.
（去掉if半倒装）

②名词性从句中的虚拟： 表“建议，要求，命令”的名词性从句都得用虚拟。
如：He suggested that the system should be changed.

③时态（混合时态的虚拟）：
如：If you had married him,you would be the wife of a gas station attendant.
“如果你（过去）嫁给他，你（现在）就会是个加油工人的老婆。”

可根据最上表格改变相应时态。追问
