1. Conditional Sentences
by YZ

3. Conditionals
There are 4 main types of if sentences in English, often called conditional sentences.
These sentences are in two halves (clauses):
the if part (if clause)
the other part where you can use words such as can, will, may, might, could and would (main clause)

4. If you heat the water to 100 degrees,
ZERO CONDITIONAL is a structure used for talking about general truths -- things which always happen under certain conditions (note that most zero conditional sentences will mean the same thing if "when" is used instead of "if"). The zero conditional is used to talk about things which are always true -- scientific facts, general truths, and so on.
if clause
If + Present Simple
main clause
Present Simple
If you heat the water to 100 degrees,
it boils.

5. 1st CONDITIONAL is a structure used for talking about possibilities in the present or in the future. The first conditional is used to talk about things which are possible in the present or the future -- things which may happen.
if clause
If + Present Simple
main clause
Future Simple, can, may
If you study hard,
you will pass the test.

6. If I had a million dollars,
2nd CONDITIONAL is a structure used for talking about unreal situations in the present or in the future. The second conditional is used to talk about things which are unreal (not true or not possible) in the present or the future -- things which don't or won't happen.
if clause
If + Past Simple
main clause
would, could, might
If I had a million dollars,
I would buy a big house.

7. would/could/might have + Past Participle
3rd CONDITIONAL is a structure used for talking about unreal situations in the past. The third conditional is used to talk about things which DID NOT HAPPEN in the past. If your native language does not have a similar construction, you may find this a little strange, but it can be very useful. It is often used to express criticism or regret.
if clause
If + Past Perfect
main clause
would/could/might have + Past Participle
If I had studied harder,
I would have passed the exam.

8. WISH / IF ONLY CLAUSES
Wish and if only can be used with would and past tenses. These structures express regrets, and wishes for unlikely or impossible things.
If only is more emphatic. (Traducción: Ójala, Desearía)
1. Past tenses are used to talk about the present.
I wish I was better looking I wish I spoke French
Don’t you wish you could fly? If only I knew more people!
Were can be used instead of was, especially in a formal style.
He wishes he were better looking.
2. We use a past perfect tense to express regrets about the past
I wish you hadn’t said that.
Now she wishes she had gone to university.
If only she hadn’t told the police, everything would be all right.
3. We use would or could...
1. to talk about future things which aren’t so much probable.
I wish / If only I could go to the party.
2. to talk about future things that we would like people (not) to do. The subject of wish and the main verb is different. So here we only use would. This often expresses dissatisfaction or annoyance: It can sound critical.
I wish you would go home. If only the postman would come!
We can use this structure to talk about things as well as people.
I wish this damned car would start. If only it would stop raining!

9. Sample rephrasing First Conditional:
- Be careful – someone’s going to see you!
- If you are careful, nobody will see you!
- If + Subject + present simple, subject + future will (aff or neg)
Second Conditional:
Kathy wants to go to the movies but doesn't have any money
If Kathy had some money, she would go to the movies.
If + Subject + past simple (neg or aff), subject + would /could/might + infinitive + complements
Third Conditional:
-Tom was not going to come to dinner the next day because you insulted him.
If Tom hadn’t insulted him, he would have come to dinner.
If + Subject + past perfect (neg or aff), subject + would/ could/might + have + pp + C
Wish / If only
I’m sorry, but I can’t help you now.
I wish I could help you.
I would have gone to the concert, but I didn’t have a ticket.
I wish I had had a ticket. / I had bought a ticket
