It gives a reason. I’ll phone my parents in case they’re worried about me We use if to talk about a reaction to, or the result of, a future action My parents will be angry if I get home late tonightI’ll be in trouble if I get home late tonight IN CASE:

We use the past for a present situation after wish. We use wish to say that we regret something, that something is not as we would like it to be: ( lamentamos algo que que no es como nos gustaría que fuese) e.g. “ I wish I knew Sue’s telephone number.” (¡Ojalá supiera el teléfono de Sue!) (As in if – clauses, we can use were instead of was after wish e.g. I wish I were taller (¡Ojalá fuese más alto!) We use past perfect after wish when you say that you regret something that happened or didn’t happen in the past (Lamentamos algo que pasó o no pasó en el pasado) e.g. I wish I had known that Ann was ill. I would have gone to see her. ( ¡Ojala hubiese sabido que Ann estaba enferma. Habría ido a verla!) I WISH: ojalá…!
I wish Activities (Past) You have to imagine that you are in a situation. For each situation, make a sentence with I wish… Example: You’ve eaten too much and now you feel sick You say : I wish I hadn’t eaten so much 1. You’ve just painted the door red. Now you decide that it doesn’t look very nice You say: 2. You are walking in the country. You would like to take some photographs but you didn’t bring your camera. You say: 3. A good friend of yours visited your town but unfortunately you were away when he came. So you didn’t see him. You say: 4. You’ve just come back from your holiday. Everything was fine except for the hotel, which wasn’t very good. You say:
I wish Continues We sometimes use would after I wish… Study this example: It is raining. Tom wants to go out, but not in the rain. He says: “ I wish it would stop raining” (¡Ojalá dejara de llover!) This means that Tom is complaining about the rain and wants it to stop. We use I wish… would … when we want something to happen or somebody to do something. The speaker is complaining about the present situation. (queremos que algo ocurra o que alguien haga algo) I wish someone would answer that telephone. It’s been ringing for about five minutes The music next door is very loud. I wish they would turn it down. I wish you wouldn’t drive so fast. It makes me nervous. We use I wish… would when we want something to change or somebody else to do something. So you cannot say “ I wish I would…” Se usa sólo cuando queremos que algo cambie o que alguien haga algo, nunca para nosotros, nunca con I
