          Listening and Writing (Student's Book: p. 46)

          MR. OK, boys and girls, we're going to do an experiment. Come a

          CHEN: bit closer. The closer you are, the more you'll see! That's

          right! Now, what's the aim of this experiment, Zhou Kai?

          ZHOU We want to find out if there's a change in weight when

          KAI: magnesium burns in air.

          MR.

          CHEN: That's right. So what do we need first?

          ZHOU Um ... We need some magnesium. How much do we need? KAI: What about this piece? Is this piece OK?

          MR. No, we need rather more than that—about two and a half CHEN: grams. We need a piece which is much bigger than that.

          OK ... And we need a Bunsen burner ... a balance ... and a

          ZHOU crucible to put the metal in ... Here they all are ... Where do KAI: we go from here?

          MR. Well, first, put the magnesium in the crucible. Then put the CHEN: crucible on the balance and weigh it.

          ZHOU

          KAI: OK...

          MR. How much does it weigh? Take a look, everyone. Is it any CHEN: heavier?

          ZHOU Um ... It weighs two and a half grams. Do you want me to KAI: write that down?

          MR.

          CHEN: Yes, write it down. What next?

          Yes ... Um, next, we're going to heat the magnesium. So I

          light the Bunsen burner. After that, I hold the crucible over

          ZHOU it ... Oh look, it's burning with a white light! It's getting

          KAI: brighter and brighter!

          MR. It's pretty, isn't it? Keep the noise down, boys and girls,

          CHEN: please.

          ZHOU Um ... lastly, we need to weigh the magnesium again ... It KAI: weighs four grams now.

          MR.

          CHEN: So what does that tell you?

          ZHOU

          KAI: It weighs a little more than before.

          MR.

          CHEN: How much more?

          ZHOU

          KAI: 1.5 grams more.

          MR.

          CHEN: And what does that mean?

          ZHOU It means that there is a change in weight when magnesium KAI: burns in air.

          You've got it! Well done! So now, let's do the same

          MR. experiment with copper. Come along, Li Kang, it's your turn CHEN: now. What do you think will happen if you heat copper? LI KANG: I think it'll be a lot heavier than magnesium. Shall I begin?

          MR.

          CHEN: Yes, go ahead!

          Listening and Speaking (Student's Book: p. 95)

          The aim of this experiment is to write a secret message with invisible ink.

          For the experiment, you need the following things: a lemon, a small container, a pen, some white writing paper, a candle and some matches.

          First, squeeze the lemon and pour the juice into a container. A glass or a cup will be fine.

          Next, take your pen and dip it into the lemon juice then write your message in large letters on a clean sheet of white writing paper.

          After that, blow on the paper to dry the lemon juice. Your secret message is ready and you can exchange messages with another student.

          Next, light a candle with the matches. Finally, hold the paper near the candle flame.

          The message will gradually appear on the paper. The words are a light brown colour.

          The message appears on the paper when you heat it because the lemon juice reacts with oxygen in the air. This reaction produces a brown coloured oxide which you can see.

          Module 2

          Listening and Vocabulary (Student's Book: p. 54)

          Hello and welcome to Education Today. Today, we're

          talking about the Internet. Is the Internet a good

          thing for education? With me in the studio are Ann

          Baker, who's a teacher, Tom Grant, who's 17 and still

          at school, and Tom's mother Pat. Welcome to the

          show, everyone. If I can talk to you first, Ann, do you

          INTERVIEWER: think that the Internet is a good thing or a bad thing?

          Well, there are good and bad things about the

          Internet, but I think we should concentrate on the

          ANN: good things. The Internet has fantastic information

          about all kinds of things, and for this reason I think

          it's very good for students to use it.

          Do you allow your students to use the Internet during

          INTERVIEWER: school time?

          Absolutely! They have Internet classes once a week. It's a chance for them to do some independent work. ANN: I make sure they have a reason to use the Internet.

          What do you think are the bad things about using the

          INTERVIEWER: Internet?

          Well, we all know that there are some terrible sites on the Internet. We must make sure that students look ANN: for information on interesting and useful sites.

          I see. Thank you. Well, I also have Pat and Tom Grant

          INTERVIEWER: with me. Tom, how often do you use the Internet?

          TOM: Every day.

          INTERVIEWER: At school or at home?

          TOM: At school and at home.

          How much time do you spend on the Internet at

          INTERVIEWER: home?

          TOM: As much time as I can. About five hours.

          INTERVIEWER: Five hours a week?

          TOM: No! Five hours a day!

          INTERVIEWER: And what do you do on the Internet? Do you study?

          TOM: Yes, it's good to study on the Internet.

          INTERVIEWER: Is it better than studying at school?

          Well, they're different. I like studying at school as

          TOM: well.

          INTERVIEWER: Pat, what do you think about that?

          Well, I'm happy when Tom is studying on the

          PAT: Internet, but he doesn't always study.

          INTERVIEWER: What do you mean?

          Well, there are a lot of music sites that he likes. And he spends a lot of time reading about his favourite

          PAT: football team.

          INTERVIEWER: So you would prefer it if he didn't do that.

          No—I want him to study and enjoy himself. But

          studying is important. And studying from books is

          PAT: important.

          INTERVIEWER: More important than studying on the Internet?

          PAT: Studying is the important thing.

          An Interview (Student's Book: p. 101)

          MR.

          HAN: Good morning Mrs. Wu. Please come. What can I do for you? MRS.

          WU: I'm worried about my daughter, Mr. Han.

          MR.

          HAN: Yes, I'm a little worried about Du Juan, too.

          Before she became interested in the Internet she was a very MRS. hard-working student. Her exam results were always very WU: good. Now she spends a lot of time on her computer. MR. Yes, she was always one of the top students in the class, but HAN: her grades have fallen recently.

          Exactly. She's changed a lot. Every day, after school, she goes straight to her bedroom and stays there for several hours.

          When I ask her what she is doing, she tells me that she is busy with her schoolwork and she needs to look for information on the Internet. But it's not true. A few days ago I discovered that she was surfing the Internet and visiting lots of different MRS. websites. She spends most of her time chatting with strangers WU: on ICQ. This is very worrying!

          I agree with you. This is a concern for many parents and

          teachers, Mrs. Wu. We're all worried that some information on the Internet may not be suitable for children. In my opinion, some websites can be very offensive. And many young people MR. seem to have a lot of trust in information they find on the HAN: Internet.

          I am also afraid that my daughter may make friends with MRS. strange people through ICQ and chat groups. I mean, there WU: are some dangerous people out there.

          People say the Internet is one of the greatest inventions. It improves communication among people and helps the

          development of science and technology. It is also easy and efficient to get new information from the Internet. However, it causes a lot of problems, too. And children need to know about MR. the dangers. If you want my personal opinion, Mrs. Wu, I think HAN: you should talk to your daughter.

          MRS. I want to talk to my daughter but I don't know very much WU: about computers. And I know she won't listen to me. MR.

          HAN: Would you like me to talk to her?

          MRS. WU: I would be very grateful, Mr. Han. I'm sure she'll listen to you. MR. Well, I'll have a chat with her. I can at least help her to be more HAN: aware of online safety. MRS. WU: Thank you very much, Mr. Han.
