Unit 4- Grammar

• Conditional sentences

In Unit 4, we learnt about conditional sentences. There are four types:

1. Type 0→ If/ When/ Unless + Present simple →We use the zero conditional to talk about something that is always true.                              -Ex.: Unless it snows, we always walk to school.
2. Type 1→ If/ Unless +present simple, will/ won't +infinitive→ The first conditional talks about the result of a possible future situation.             -Ex.: If they pass their exams, I will buy them a nice present.
3. Type 2→ If +past simple, would +infinitive→ The second conditional talks about the result of an imaginary situation.                                         -Ex.: I would choose red as our team colour if I were the captain.
4. Type 3→ If +past perfect simple, would have +past participle→ We use the zero conditional to talk about something which is always true           -Ex.: If they had played in the rain, they would have fallen in the mud.
