2. FIRST CONDITIONAL  We use the first conditional to speak about a possible present or future situation and its results:  "If you are getting bored, I´ll change the subject"  "If you keep on talking to me like that, I´m going to walk out of this room right now".  "If I have enough money next year, I´ll buy a new car"  “If the weather is better tomorrow, I might go for a walk on the beach"  “If I find a better job, I won´t be working here this time next year".  "If you leave now, you shouldn´t come back late"

3. FIRST CONDITIONAL

4. SECOND CONDITIONAL  We use the second conditional to talk hypothetical or improbable situations in the present or future:  "If she was earning more money, she would be able to have a holiday this summer"  "If I wasn´t working tomorrow, I would go out with my friends tonight".  "If the weather was better, I would certainly be feeling happier".  "If I won the lottery, I could give up work for ever”.

5. Second Conditional  With the verb TO BE you can say:  If I were the president, I’ d reduce the taxes. OR  If I was the president, I’ d reduce the taxes. This happens with the pronouns I, he, she, it. However when we give advice we say:  If I were you, I’ d be more careful.

9. MIXED CONDITIONALS  If we want to refer to the present and the past in the same sentence we can mix tenses from two different types of conditionals:  I wouldn’t be in this mess if I had listen to your advice.  Jill would have left her husband by now if she didn’t still love him.
