教学设计方案
Lesson 2

教学目的：

教具 录音机，小黑板（写有不规则动词若干）。
教学过程
Step 1 Revision
　　1. Revise Have got …？
　　T: Have you got a ruler?
　　S: Yes. I have.
　　T: Can I borrow it.
　　S: Certainly. Here you are.
　　T: Thanks.
　　2. Revise the Present Perfect Tense
　　教师先说出几个句子，然后让学生接着再说一句，表明上句的结果。如：
　　T: I have returned the book to the library. S: Now I can borrow a new one.
　　T: She has finished her homework. S: She can have a rest (go out and 　　play).
　　T: He has bought a new car. S: He can drive a new car now.
　　T: We have seen the new film. S: It’s about a small white cat. It’s very interesting.
　　T: They have lost the dog. S: They have put the dog’s photo in the newspaper. They want to find it.
　　让学生来总结出其构成：have + v. ed
　　出示小黑板，要求学生将上面列出的不规则动词的过去分词形式写出。
Step 2 Presentation
　　1．利用已学过的对话引出有关借书的话题。
　　T: Have you got the book……？
　　S: Yes. I have.
　　T: Can I borrow it?
　　S: Certainly. Here you are.
　　然后教师问学生：Do you often borrow books? Where can we borrow books from? 引出Library话题。
　　2．让学生谈谈自己借书的经历，丢失了书该怎么办。
　　3．让学生默读一遍课文（五分钟左右），并用铅笔划出课文中的生词，鼓励学生根据上下文来判断这些词的意思。然后回答下列几个问题：
　　1. What did my grandma do when she was young?
　　2. What does she like?
　　3. Do you like reading? Do you often borrow books from the school library?
　　4. Did my grandma lose the library books last week? What book?
　　5. What idea did the library think of?
　　6. What other good idea do you have to get the lost books back?
　　教师对学生标出的新单词进行讲解，并对文章中新出现的重点词汇和短语。
　　1）used to
　　意为“过去经常”，它只有过去式，用于各种人称的单、复数，表示过去存在的，
但现在已经停止的情况或习惯，后接动词原形。例如：
　　They used to come on foot，but they don’t do that again. They often come by bus. 他们过去经常步行来，现在不了。他们经常乘车来。
used to的疑问形式和否定形式可以用助词did或自身形成构成。美国人多用助动词 did；英国人多用used to本身。如：
　　他过去不常抽烟。

　　　　
　　注意区分be used to所表示的意思是“习惯于……”，后跟名词或动名词，used是一个形容词。例如：
　　I’m not used to drinking. 我不习惯喝酒。
　　She is used to running in the morning. She is a very fast runner.
　　2）Her hobby is to read. 她的业余爱好是读书。
　　to read 是一个动词不定式，在句中用作表语。如：
　　Her wish is to be a singer. 她的愿望是成为一个歌手。She sings a lot every day.
　　3）pay for意为“给……报酬”，“付款”。常见句型有：(1) pay for+货物，(2) pay+名词／代词+for+物。例如：
　　How much did you pay for that book？20 yuan
　　I’ll pay you five yuan for it．我将为此给你五元钱。
　　I’m afraid I can’t pay you anything for it．我恐怕不能为此给你任何报酬。
　　4）come up with= find or produce (an answer)意为“提出，提供”，它是由动词和介词一起构成的短语动词。它的另一个意思是“赶上”。例如：
　　I hope you can come up with a better plan than this. 我希望你能提出个更好的计划。
　　5）the lost books lost=missing丢失的。英语中单个分词（包括现在分词和过去分词）也能作定语用，它们一般放在名词的前面。又如：a stolen car一辆失窃的汽车；a broken wind。一扇破的窗。
　　4．放录音，让学生先听，然后跟读。
　　5．学生熟悉课文后，学生回答练习册 Ex 1.的问题。
Step 3 Practice
　　1．Do Workbook Lesson 2, Ex 1. in class.
　　2．让学生根据课文内容改编成一短剧。并分角色表演。（见教学建议：表演：The Lost Book）

　　1．总结本课的重点短语的用法：used to put down pay for come up with think of
　　2．简要叙述课文内容。
