Listen and answer the questions.
1. Is the football Tony’s?
Yes, it is.
2. Are the crayons Betty’s?
No, they aren’t.
3. Whose gloves are these?
They are Betty’s.
“Tony’s” 意为“汤姆的”，其构成方式是在名词后面加“’s”,是名词所有格的一种形式。
*当可数名词以s结尾时，其名词所有格形式是名词
后加“ ’”。如：Teachers’Day 教师节
注意：Kate and Lucy’s room 凯特和露西的房间(两人共有的房间）；Kate’s and Lucy’s rooms 凯特的房间和露西的房间（两人各自的房间）。
另外，of 短语也可以用来表示所属关系。如：a map of China 一幅中国地图

Listen and read.
Ms Li: Welcome back to school, everyone! First of all, come and look in the lost and found box! There are a lot of things in it. Whose bag is this?
Ling: Oh sorry! It’s mine. Are my crayons there too?
Ms Li: Are these crayons yours?
Ling: Yes, they are and this eraser too. Thank you.
Ms Li: Whose tapes are these?
Daming: They’re mine.
Ms Li: Here’s a purple wallet!
Tony: It’s mine. Look! Here’s my name“Tony”! Thank you.
... ... ...
—Whose bag is this?
它是谁的包呢？
— Oh, sorry! It’s mine.
哦，不好意思，是我的！
这是由疑问词whose引导的一个特殊疑问句。whose意为“谁的”，表示所属关系，在句中既可单独使用，也可与名词连用；其答语用名词性物主代词或名词所有格。如：
—Whose T-shirt is this? = Whose is this T-shirt?
—It’s hers. / It’s Sally’s.
... ... ...
Language points
1. First of all, come and look in the lost and found box!
首先，看看失物招领箱吧！
“first of all” 表示“首先”，常常放在句首，通常情况也可以用firstly等替换。
e.g.: First of all, let me introduce my friends Mike to you.
Firstly, I would like to thank all of you for supporting me these past couple of weeks.
首先，我想感谢过去几个星期一直陪伴我，让我坚强地走出悲痛的所有人。
2. Everyone, please be careful with your things from now on.
从现在开始请大家小心保管自己的物品。
“be careful with…” 意思是“小心……”,此时的be cafeful 等同于 look out.
Please be careful with your money.
“from now on” 表示“从现在开始”。
e.g : From now on, students need much more time to rest.

辨析：watch，look，look at与see
1、watch是及物动词，意思是“观看；注视”，常用来指看电视、看球赛、看戏等。
2、look为不及物动词，单独使用，用以引起对方的注意。
3、look at是由动词look和介词at组成的词组，后面可以带宾语，侧重“看”的动作。
4、see为及物动词，意为“看见”，侧重“看”的结果。
用自己的文具做道具，用以上句型两人一组编对话。
A: Whose bag is it?
B: It’s mine.
A: Is this your bag?
B: Yes, it’s my bag./it’s mine.
No, it’s not my bag./it’s not mine.
