The grammar items in this unit focus on unreal conditionals. Unreal conditionals are used to express a condition or situation that is unreal or imaginary.

The students in Grade 2 have a general understanding of this grammar, so what they should focus on is the forms of the verbs and different tenses when they use sentences with unreal conditionals. What’s more, based on their vocabulary and speaking ability, it is vital for them to use unreal conditionals freely and correctly. 1.

Students will be able to understand what an unreal conditional is，especially the statement about an unreal or imaginary present situation. 2.

Students will use unreal conditionals to talk about an imaginary present, past and future situation freely and correctly and perform an game to practice and strengthen it.

Students are expected to learn when to use unreal conditionals and how to use unreal conditionals correctly, especially the inverted structure (倒装结构)of unreal conditionals. Students are expected to use what they have learnt to complete the interview by using unreal conditionals to state an imaginary present situation.

Step 1 Greetings. Say hello to everyone. Step 2Lead-in

Look at a picture and give some hints to them. Ask students to translate the classic line into English. Then the teacher can make some corrections to introduce the topic of this lesson. Step 3 More examples Show the students another two sentences to make them to distinguish the differences between if real conditionals and if unreal conditionals. 1.If my mother comes to our school tomorrow, I will be happier. 2.If Xi Dada came to our school tomorrow, I would be happier. Step 4 Explanation

What is an unreal conditional? An unreal conditional is a statement about an unreal or imaginary condition or situation. In general, we can use it to talk about three different conditions. This lesson we are focused on the first one(an imaginary present situation). Step 5 A general grasp of some rules Look at the sentences. If I had a lot of money now, I could buy a ticket. 1

If I bought a ticket today, I would be on board. If I were on board now, I should sail for America. Ask the students to pay attention to the forms of the verbs used in if-clauses and main sentences. Encourage them to try to find out the basic rules about unreal conditionals stating an imaginary present condition. Then ask one student to write down the rules that he/she summarizes.

Main sentence If- clause An unreal or

would/could/should did imaginary

/might +do were(be)

present

condition

Step6 More examples

Give the students more sentences that are contrary to the past condition to find out the rules, for example, Jack : Rose, if I hadn’t won the ticket then, I wouldn’t have been on board. Rose: If you hadn’t been on board at that time, I wouldn’t have met you. Summarize the rules:

If sb.had done sth, sb.would/should/could/might have

done sth.

Give the students more sentences that are contrary to the future condition to find out the rules, for example, If I survived, I would marry you some day.

If we should marry, we could live a happy life.

If we were to live a happy life , we might have many children of our own in the future.

If sb did/should do/were to do sth, sb

would/should/could/might do sth

Step 7 Notes

省略if的虚拟条件句

1.条件从句中如含有

should，were，

had 三个助动词或be动词，可以把if省略，并把这三个词提至句首。

1). If I were you, I would try it again. Were I you, I would try it again.

2).If he had been there yesterday, he would have seen the film.

2

Had he been there yesterday, he would have seen the film. 3).If it should snow tomorrow, we wouldn’t go out.

Should it snow tomorrow, we wouldn’t go out. 2.如果省略的条件句中动词是否定形式时,不能用动词的缩略形式. Step 8 Summary of this class ★Unreal conditionals ★Inverted structures(虚拟条件句中的倒装结构) 省掉if,将were, had, should提到主语之前。

Step 9 Consolidation Divide the students into three groups and encourage them to take part in this activity actively. The group which gets the most points wins. Step 10 Homework Review what we have learned in this class and finish off the relevant exercise on your textbooks. Blackboard design：
