wish后be动词只能用were吗？

Question

例：I wish I _________（was，were）as young as you.
另求此题是不是选第二个had：How I wish I_________(have,had,didn't have,don't have)such a good chance.

Answer 1

How I wish I had such a good chance!我多愿我有这样的好机会！
I wish I were as young as you.但愿我象你一样年轻。

看情况：

现在相反用were
过去相反用had been
如：
I wish I were a girl.但愿我是女孩。
I wish I had been to Beijing.但愿我到过北京。

Answer 2

虚拟语气中谓语动词使用过去式，表示希望、意愿、假设等不能实现愿望本句中意思：我希望可以跟你一样年轻。这是表示一个不能实现的想法，采用虚拟语气，wish后用were。I wish i had bought that shoes.我多么希望我买了那鞋子。（表示与事实相反，其实我没有买）

Answer 3

were 虚拟
