CONDITIONA L SENTENCES
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"
FIRST CONDITIONAL
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”.
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.
SECOND CONDITIONAL
THIRD CONDITIONAL We use the third conditional to speak about hypothetical situation in the past that can´t be changed now: "If you had been concentrating, you wouldn´t have made those stupid mistakes". "If she had known Joe better, she would have never married him".
Third Conditional
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.
CONDITIONAL CONJUCTIONS: UNLESS - It´s used instead of "if...not" "Unless you help me, I won´t be able to do it” (If you don´t help me,...) Or it´s used instead of "except if..." "I don´t know why she was angry, unless my comments had annoyed her"
CONDITIONAL CONJUCTIONS: IN CASE "I´m going to leave early in case it takes a long time to get there" “I took a sandwich in case I got hungry on the journey" "In case you haven´t heard the news, I´ll tell you"
CONDITIONAL CONJUCTIONS: ON CONDITION THAT / AS LONG AS / PROVIDED (THAT) / PROVIDING (THAT) - Something must happen or be true for the other part of the sentence to happen or be true. "As long as you leave before 3, you´ll catch the plane without problems" "I´ll go back to work tomorrow provided / providing (that) I´m feeling better". "He told me I could stay as long as I was quiet".
CONDITIONAL CONJUCTIONS: EVEN IF.../ WHETHER...OR NOT - To talk about a possibility that doesn´t affect what is stated in the other part of the sentence. "Even if she apologizes, I won´t forgive her" "Even if I had done what you suggested, I would be in the same position now" "Whether we had studied or not, we would never have passed that exam; it was too difficult.
CONDITIONAL CONJUCTIONS: Compare: "Even if we ran, we would miss the train” (We would miss the train whether we ran or not; it wouldn´t make any difference). "Even though we ran, we missed the train" (We ran, but we missed the train anyway.)
CONDITIONAL CONJUCTIONS: IF I HAD KNOWN... / HAD I KNOWN... "If I had known that Rose was working for this company, I would have never accepted the job." “Had I known that Rose was working for this company, I would have never accepted the job."
