2、易懂；再利用设计好的语言情景，加以运用和巩固，以笔头、口头等多种形式将语法练习有机地、灵活地融会于各种课堂任务之中。通过对比归纳，有助于学生从整体上进行掌握，帮助学生将语法知识加以巩固和“内化”，以培养学生自主学习与探究的能力，提高准确使用语言的能力。Teaching aims:After learning this part, the students will be able to:1. use unreal conditionals of the present, past or future time;2. improve reading abilities and the abili
3、ty of using unreal conditionals;3. master some useful language points.Teaching procedures:Step 1 Lead-in1.

5、the UK, I would expect a present. If I got married in Italy, I would have to give a present. Should you come to Brunei, you would have to take off your shoes before going into someones house.Explanation为了使枯燥的语法课变得生动有趣，所以在导入部分用了一句浅显易懂的句子导入新课，让学生知道什么是虚拟语气，然后通过复习的方式将阅读课中出现的虚拟语气句一一找出,对虚拟语气有进一步的了解。Step 2
6、 Presentation (PPT6-17)Unreal conditionals can be used in three different tenses:1. to state a present condition or situation that is not real or is imaginary. E.g. 1) I could reach the book if I were a bit taller. 2) If I had the chance, I might want to be a business consultant.the Pattern we use i

9、itionals to refer to an imaginary past action. E.g. If the man had pointed with his first finger while he was in Brunei, everyone would have thought that he was very rude.

11、 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. unreal future conditionals:If was/were/did/should/were to , would/should/might do. Practice: 1) 假如我要出国，我就会去中国。If I were to go abroad, I would go to China.2) 万一明天下雨，我们的运动会就推迟。If it
12、 should rain tomorrow, our sports meeting would be put off.三种用法的总结：表示与事实情况相反条件从句的谓语形式主句的谓语形式表示与现在事实情况相反(present)过去式(did/were)(be常用 were)would/could/might/should + do表示与过去事实情况相反(past)过去完成式(had +done) would/could/might/should +have done表示与将来事实情况相反(future)过去式(did)/(were)should + do were to dowould/coul
13、d/might/should + do4. 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 e
14、arlier, 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.Explanation这一环节有四部分组成，前面三步是就虚拟语气在现在时、过去时和将来时的不同用法以及常用结构。为了便于学生理解和记忆，所以在讲完三种
15、用法后用表格来个总结，使学生一目了然；其中还需学生注意was在非正式英语可以代替were; 当If从句中含有should/were/had时可以省略if, 然后将这三词可以提到句首，引起句子倒装。Step 3. Practice Do the exercises on Page 40 and 41.Explanation语境的实现以语篇为载体。在学习语法知识、巩固练习时, 要重视通过篇章语境, 使学生更好地理解，并提高语法的运用能力。这一环节的设计就是将虚拟语气与对话和阅读相结合，在具体的语境中讲语法，不至于死记硬背，死抠语法。Step 4. More practice（PPT18-22）1.
