Class IX: Second and Third Conditional

For this class we have the following goals:

• To identify and apply the second and third conditional.

The Second Conditional

The second conditional uses the past simple after if, then 'would' and the infinitive:

• if + past simple, ...would + infinitive

(We can use 'were' instead of 'was' with 'I' and 'he/she/it'. This is mostly done in formal writing).

It has two uses.

1. First, we can use it to talk about things in the future that are probably not going to be true. Maybe I'm imagining some dream for example.

• If I won the lottery, I would buy a big house.(I probably won't win the lottery)
• If I met the Queen of England, I would say hello.
• She would travel all over the world if she were rich.
• She would pass the exam if she ever studied.(She never studies, so this won't happen)

2. Second, we can use it to talk about something in the present which is impossible, because it's not true. Is that clear? Have a look at the examples:

• If I had his number, I would call him. (I don't have his number now, so it's impossible for me to call him).
• If I were you, I wouldn't go out with that man.

How is this different from the first conditional?

This kind of conditional sentence is different from the first conditional because this is a lot more unlikely.
For example (second conditional): If I had enough money I would buy a house with twenty bedrooms and a swimming pool (I'm probably not going to have this much money, it's just a dream, not very real)
But (first conditional): If I have enough money, I'll buy some new shoes (It's much more likely that I'll have enough money to buy some shoes)

Exercises

• Set 1 Second Conditional 

The Third Conditional

We make the third conditional by using the past perfect after 'if' and then 'would have' and the past participle in the second part of the sentence:

• if + past perfect, ...would + have + past participle

It talks about the past. It's used to describe a situation that didn't happen, and to imagine the result of this situation.

• If she had studied, she would have passed the exam (but, really we know she didn't study and so she didn't pass)
• If I hadn't eaten so much, I wouldn't have felt sick (but I did eat a lot, and so I did feel sick).
• If we had taken a taxi, we wouldn't have missed the plane
• She wouldn't have been tired if she had gone to bed earlier
• She would have become a teacher if she had gone to university
• He would have been on time for the interview if he had left the house at nine
