...
建议2：让学生根据家庭作业所做的卡片信息，进行物品主人的确认。
这样既可以检查学生的家庭作业情况，又可以训练学生的语言表达能力。
Step 3：Present “Lost and Found”
建议1：教师利用多媒体课件展示寻物启事和失物招领启事，让学生判断Lost 和Found，并填到卡片上。

______： I lost my school ID card. I must find it. Call Tom at 685­6034.

______： Some keys are in Classroom 7E. Are they yours？ E­mail me at maryg2@gfimail.com.

建议2：抽查上一课时留下的家庭作业(让学生写出寻物启事和失物招领启事)，把学生书写的卡片用投影仪展现出来，和全班一起阅读。同时检查启事中是否有错误，并给予指正。
Step 4：Write “Lost and Found”
1．教师用多媒体展示出寻物启事，让学生发现写寻物启事的要点。
For example：
T：Today we are going to learn how to write “Lost”．Look at the “Lost” below and find out the important information about it.

Lost： I lost my baseball. Yellow and red. Call Bob at 405­6678.

Lost： I lost my ID card. My name is Mike. Please call 843­9096.

S3：Color.
S4：Telephone number.
T：Yes.You have done very well.If we write “Lost”，we must write the lost thing，its color，the person's name，and telephone number.We can also put a picture of the thing on it.
让学生根据要点检查自己昨天所写的寻物启事，并改正或补全。
2．教师展示出失物招领启事，让学生发现写失物招领启事的要点。
For example：
T：If we pick up something，how should we write “Found”？Look at the “Found”below and then tell me the way to write “Found”.

Found： Is this your schoolbag？ Please call Anna. Phone # 556­0203

Found： A set of keys in the lost and found case. Call Alan at 886­4779.

S1：The thing.

让学生根据要点检查自己昨天所写的失物招领，并改正或补全。

建议：教师用多媒体展示出课本3a的内容，让学生补全信息。

______：My notebook My ______ is David. Please ______ me at 679­8871.

______：A set of keys Are these ______？ Call Jenny at ______.

Step 6：Writing
让学生用英文写出简单的寻物启事和失物招领启事。建议教师把学生的作品在实物投影仪上展示，便于修改和提供写作案例。
For example：
T：OK，let's try to write your own lost or found notice with your name and phone number.
(The students write their bulletin board messages and the teacher moves around the classroom offering help.)
T：Let's read some of your messages.
Step 7：Task
1．复习单词：让学生完成Self Check的第一部分，写出所知道的学习用品。
建议教师采用竞赛的方式，看谁写的最快最多，可以选几个同学到黑板上去写。这样既可以检查学生的单词掌握情况，也可以调动学生学习英语的积极性。
2．写新单词：让学生在练习本上写出本单元所学的其他单词。
Step 8：Pronouns
让学生完成Self Check的第二部分，用代词填表。

I	me	my	mine
	you		yours
	her		hers
he	him

Step 9：Conversation
让学生完成Self Check的第三部分，看图写对话。训练学生用目标语言说话、写作的能力。
For example：
T：Look at the picture，please.What are the first pair of students talking about？Who would like to read it?
S1：Is that your schoolbag?
S2：No，it isn't.
T：OK，now what may other people talk about？Complete the conversations using “—Is this/that...？—Yes，.../No，...”
Then let the students read the conversation with their partners.
Step 10：Homework

a set of 意思是“一套，一副，一组”。后面跟可数名词复数，在句中作主语时，谓语动词的单复数形式由set决定。
例如：这串钥匙是我的。 This set of keys is mine.
