3. The Zero Conditional describes situations that are always true. If has the same meaning as when or whenever. e.g. If you park your car on double yellow lines, you pay a fine. (Whenever you park illegally, you pay a fine.) In the condition clause, we can use a variety of present forms. In the result clause, there can only be the present simple or imperative. Note that we are not talking about a specific event but something which is generally true. If you visit London, go to the Tower of London. (Imperative) e.g. If I go to school, I get up at seven. (Present Simple)

5. We use the First Conditional to talk about future events that are likely to happen. We do not use will in an if clause to describe future activities. e.g. If he studies hard, he'll pass the exams. If we don't get the contract, we'll waste a lot of time and money. We make if clauses with if + present tense and main clauses with will + infinitive. So the first conditional is used to talk about things which are possible in the present or the future — things which may happen. If it's sunny, we'll go to the park. Roni will be sad if Danny leaves. If you cook the dinner, I'll wash the dishes.

7. The second conditional (also called conditional type 2) is a structure used for talking about unreal situations in the present or the future. We use different verb forms in each part of a second conditional: IF clause: if + subject + simple past verb* Main clause: subject + would + verb Note that this "simple past" form is slightly different from usual in the case of the verb BE. Whatever the subject, the verb form is "were", not "was": e.g. If I were rich, I'd buy a big house. If she were happy in her job, she wouldn't be looking for another one.

9. The third conditional (also called conditional type 3) is a structure used for talking about unreal situations in the past. e.g. If you had saved your money, you could have bought a computer. Like the other conditionals, a third conditional sentence consists of two clauses, an "if" clause and a main clause: e.g. If it had snowed, we could have gone skiing. if clausemain clauseexplanation If I had studied harder, I would have passed the exam.I failed the exam, because I didn't study hard enough.

10. If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma. We use different verb forms in each part of a third conditional. So the third conditional is used to talk about things which did not happen in the past. e.g. If you had saved your money, you could have bought a computer. (However, you didn't save your money, so now you can't afford a computer) If clause Main Clause if + subject + past perfect verb subject + would (OR could, OR might) have + past participle
