老师：同学们好，我是东城区教师研修中心的谢晓雅老师。今天我们来学习外研版英语教材七年级下册 module one lost and found unit three language in use， what does lost and found mean， yes it means。失误招领 in Chinese。
老师：Lost is the past tense of loose and found is the past tense of find. That means this module is about losing things and finding the lost things. In Unit 1 and 2, we have Learned about some things that people often lose. Do you remember them? Let's go over them. What's this? Yes, it's an eraser. Read after me. Eraser. Students sometimes lose their erasers. What else do students lose? What are these? Yes, crayons. Let's read it again. Crayons. Students may lose their crayons too.
老师：And here is another thing that some students lose at school. What's it? Yes, it's a tape. Tape. What are these? They are gloves. Let's read it again. Gloves. Students sometimes lose their gloves at school. But not just students lose their gloves. Other people also may lose their gloves. And besides gloves, what else do people sometimes lose? They sometimes lose their watches. Read the word after me, watch. Watch. And there's another thing that people possibly lose. Do you know what it is? It's a mobile phone.
老师：Mobile phone. What else do many people, especially tourists, often lose, right? Cameras. Read after me, camera. Camera. Mobile phones and cameras are very important things for us and we are afraid of losing them. There is another thing that people are very afraid of losing. Do you know what it is, right? Wallet. Read after me. Wallet. Wallet. All of us may lose things and we may also find something that other people lose. Then what should we do when we lose a thing or find a lost thing? Do you remember what Miss Lee does when she finds the things in the lost and found the box? She asks the students.
老师：Of course, if you find a lost thing, you can also ask other people. So the first way is to ask other people. Then how do we ask an answer about a lost thing? What words do we often use? Let's look at these sentences. Please read them with me. Whose tapes are these? They are mine. Look at this. Nice watch. Is it yours, too? Thamming? No, it isn't. It's leanings. Yes, it's hers. So what word do we use to ask who something belongs to? Right? We use whose plus a noun. And what words do we use to answer the questions? Yes. Mine, yours, hers. What do they refer to in these sentences? They refer to my tapes, your watch and her watch. My, your and her. So.
老师：作形容词性物主代词mine， yours and hers 叫做名词型物主代词。那为什么这些句子中用了名词性物主代词，而没有用形容词性物主代词加名词的形式？形容词性物主代词和名词性物主代词究竟有什么不同？该如何正确使用这两类不同的物主代词？我们来看两个例句， is this your football are my crayons there too。从这个两个例句我们可以看到 your 和 my 分别用在名词 football 和 Crayons 的前面。所以我们说形容词性物主代词起形容词的作用用在名词前，那么名词系物主代词。同样，我们来看两个例句， your pen is better than mine， i dont like my watch， i like hers。
