I WISH I WERE A BIRD。怎么这句子里面用WERE，不用WAS啊？是不是书上写错了 I wish I was you语法正确吗？

i wish i were a fish.\u4e3a\u4ec0\u4e48\u662f\u7528were\u800c\u4e0d\u662fwas

\u865a\u62df\u8bed\u6c14\u5c31\u662fwere\u3002
if i were you
if you were me
if they were dogs

因为是I wish 我希望但是不能实现所以是假设的情况.就用虚拟语气.用虚拟语气时,无论主语是I,you,还是he和复数的they等等都要用were

这是一种虚拟语气（如果没学过这个语法可到网上查）。

wish后接的宾语从句中只能用一般过去时（be的过去式用were)或过去完成时。

非正规场合下可用was。

一定要注意：可以用was，只不过不正式而已，不能出现在书面语中。

在虚拟语气的句子中
所有的be动词一律都是were，
不用计较是第几人称，单复数的

虚拟语气
一般情况下是用WERE的
但是在实际运用当中用WAS也不算错

were在这里是虚拟语气
表示愿望中的情形（现实不可能的）
