A.would take B.took C.will take D.takes
2、Do you ever wish you ___C_____?
A.can fly B.have flown C.could fly D.would fly
3、填空：If I __were_ (be) you,I __should not be _____ (not be) discouraged at all.
注：1、为什么不选A?
2、为什么不选B?
3、我填的是were；wouldn't be .wouldn't be 和should not be
有什么区别?怎么翻译?

1.D这是真实条件句,用一般现在时
2.C这是虚拟条件句,对现在的虚拟 have flown 是对过去的
在wish的虚拟条件句中,对现在的对现在,过去,将来,分别采用一般过去时,过去完成时,和would,could,might+动词原形,不能用should
3.were型虚拟句,也是对现在的虚拟,
would,should的区别即情态动词意义的区别
would会,should应该
这一空两个都可以填
