Grammar explanation

Imagined, wished for or unlikely situations are considered 'unreal' time. When we are talking about these situations, we often shift the verb form backwards. For example, the present changes to the past, and the past changes to the past perfect. The tense change suggests a distance from reality.

Wish and if only

We use wish and if only to talk about things that we would like to be different in either the present or the past. If only is usually a bit stronger than wish. 

The present

We can use wish/if only + a past form to talk about a present situation we would like to be different. 

I wish I knew more people my own age.
If only drivers paid more attention to cyclists.

Would is used when the speaker wants someone or something else to change. It often expresses annoyance.

I wish people wouldn't eat noisily at the cinema.

The past

We can use wish/if only + a past perfect form to talk about something we would like to change about the past. 

I wish I hadn't stayed out so late last night. I'm really tired today.
If only we'd known this company was going to close, we wouldn't have recommended them. 

The future

Note that we don't use wish to talk about our wishes for a future event.

I wish you pass the exam.

This is not talking about an unreal time; it's a wish for the future. We usually use I hope to express wishes for the future.

I hope you pass the exam.

It's (high) time

We can use the expression it's (high) time + subject + past verb form to say it is time to do something now that should have been done a long time ago.

It's high time we went to bed.
It's time we took responsibility for our planet. 

As if/as though

We can use as if and as though to talk about how a situation appears or seems. As if is more common than as though.

Some people behave as if their actions had no consequences.
It was as though she hadn't heard me. 

When we follow as if/as though with an unreal tense, we are saying we don't think the statement is really true. 

Would rather

Would rather is used to express preference about actions.

I'd rather buy less, but better quality.

When the subjects of the two clauses are different, we often use unreal tenses.

They would rather we didn't wait too long before letting them know our decision.
I'd rather you didn't eat dinner on the new sofa.
