How to use 'wish'
Hi, everyone. Tom here, from BBC Learning English in London. And today, I'm going to tell you what to say after the word wish.
When we're talking about wishes, we're talking about situations that are imaginary or unreal. To show this, after saying 'I wish', we use the past to talk about the wish, which is in the present.
愿望是对某种情况的想象或不真实的事情。为了说明这一点， 'I wish'之后通常跟过去式表示如今的某种心愿。
So, I could say: I wish I had a cup of tea. Ah, thank you!
Now, if we want to make a wish about the past, we need to use the past past - or the past perfect.
For example: I wish I had chosen a more formal shirt before I filmed this video today.
