When reporting structureThe way in which the parts of a sentence, clause or expression are arranged. E.g.: make somebody + infinitive in "The teacher made me rewrite the composition."s such as wish, would rather, it's (high) time etc., the same rules apply as in the case of reporting second and third conditional sentences.

We use this structureThe way in which the parts of a sentence, clause or expression are arranged. E.g.: make somebody + infinitive in "The teacher made me rewrite the composition." when there is a chance that something may happen or somebody (but not the person who wishes) may change their (perhaps annoying) habit or behaviour.

I wish it would stop snowing.
I wish you wouldn’t keep coming to class late.
Jean wishes I would give up smoking.

wish/if only + subject + past perfect

wish/if only + subject + past tense

If only I could talk to her! = I wish I could talk to her!

Note the similarity between the subordinate clauseA clause that cannot be a sentence in itself. It is joined with a main clause. E.g.: I wouldn’t go there if I were you. ("if I were you") When I arrived he was surfing. ("when I arrived") of the second conditional and the one mentioned above. Actually, if you complete the sentences above, you will get a second conditional sentence.
