在表示一种愿望或理想是，一般用were而不用was

这是虚拟语气.
虚拟语气中不论第几人称be动词都用were.

希望...表示虚拟，后面用was were都可以
还例如

We wish Mary were / was here.
He wishes he were / was rich.
She wishes she were / was flying in the sky.
He wishes he weren’t / wasn’t studying in this university

扩展阅读：if he were here 虚拟语气 ... my feelings were when he ... 为什么是i were 不是i was ... we were here图文攻略 ... we were here双人攻略 ... if i were him 还是he ... if he was 还是were ... here 后面要就近原则吗 ... we were here 剧场 ...
