would rather 和perfer的区别和用法？？

fool
1.would rather表示"宁愿"

　would rather do
　would rather not do
　would rather… than…　 宁愿……而不愿。

例:
----Shall we go skating or stay at home?
----Which ___ do?　　　　　
A. do you rather　　B. would you rather　 C. will you rather　 D. should you rather
答案B。本题考查would rather的用法，would rather +do sth 意为"宁愿"，本题为疑问句，would 提前，所以选B。

2.would rather 后接虚拟语气的用法
在would rather后面所跟的从句中，也可用虚拟语气，表示愿望，意为“宁愿”、“但愿”。其形式为：
1 ) " would rather +主语+动词过去式"表示现在或将来的情况。例:
I would rather you went next Sunday．
我愿你下星期天去。
2 ) " would rather +主语+动词过去完成式"表示过去的情况。例：
I'd rather you had not given up the job then.
要是你当时不放弃那个工作就好了。

3.还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。

　If I have a choice, I had sooner not continue my studies at this school.
　I would rather stay here than go home. = I would stay here rather than go home
