Lead-in Enjoy a song

If you were my eyes. If I could see, I would easily tell days from nights. If I could see, I would firmly hold your hand in the crowd; If I could see, I would take you to travel around the world, and I would hug you from your back amazing. If I could see, my life would absolutely be different; maybe what I want and what I love would be extraordinary…

Tell students: The situations are not real or are imaginary. We call them unreal conditionals. Unreal conditionals state a condition or situation that is not real or is imaginary.

Step 2 Learning We use unreal conditionals to state a present condition or situation that is not real or is imaginary.

e.g.

1) If I got married in UK, I would expect a present. 2) I could reach the book if I were a bit taller.

3) If I had the chance, I might want to be a translator. Ask students to tell the Pattern we use in unreal conditionals to state a present condition or situation. If… was/were/did … , …would/could/might do …

Practice: 1) 假如我有更多的时间，我就学习德语了。If I had more time，I would study German. 2) 要不是她这么忙，她就会出席今天下午的会议了。

If she were/was not so busy, she would attend the meeting this afternoon. TIP: 1) Would, could and might are often interchangeable, but with some difference in meaning. Would → intention; plan

Could → ability; possibility

Might → probability

2) In written English or in formal situation, we usually use were in If-clauses in place of was. However, in everyday conversation, was is often used. We also use unreal conditionals to refer to an imaginary past action. e.g. 1) If you had joined the chat room ten minutes ago, you would have known what we were talking about. 2) If the man had pointed with his first finger while he was in Brunei, everyone would have thought that he was very rude. We form unreal past conditionals like this: If … had been/done…, …would/could/might have done…

Practice: 1) 如果他抓紧时间，他本来能赶上那趟火车。If he had hurried, he could have caught the train. 2) 如果你昨天告诉他，他也许会提些建议。If you had told him yesterday, he might have made some suggestions. We use unreal future conditionals to talk about imaginary future situations. e.g.

1) If I had time tomorrow, I would certainly help you. 2) If I were to fail my Maths test, I would have to take it again at the end of the term..

3) If he should come tomorrow, I would talk to him about it. We form unreal future conditionals like this: If…was/were/did/should/were to…, …would/should/might do.

· Practice: 1) 假如我要出国，我就会去法国。If I were to go abroad, I would go to France. 2) 万一明天下雨，我们的郊游就推迟。If it should rain tomorrow, our picnic would be put off.

We can also put should, were and had at the beginning of an unreal conditional sentence. In this case, if is not needed any more. e.g.

1) If you should make a mistake, you should not be embarrassed. →Should you make a mistake, you should not be embarrassed.

2 ) If you had told me earlier, I would not have this problem now. →Had you told me earlier, I would not have this problem now. 3) If you were to take the train, you would be there much sooner. →Were you to take the train, you would be there much sooner.

We Can also use could + the present perfect with the if-clause for unreal conditionals. e.g. If I could have told you about cultural difference between Italy and the UK, I would have.
