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?

学习啦在线学习网 KAI: magnesium burns in air.
MR.
CHEN: That's right. So what do we need first?
学习啦在线学习网 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
学习啦在线学习网 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...
学习啦在线学习网 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?

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

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

MR.
CHEN: How much more?

学习啦在线学习网 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)
学习啦在线学习网 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.
学习啦在线学习网 After that, blow on the paper to dry the lemon juice. Your secret message is ready and you can exchange messages with another student.
学习啦在线学习网 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.
学习啦在线学习网 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.

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.
学习啦在线学习网 HAN: Yes, I'm a little worried about Du Juan, too.
学习啦在线学习网 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.
学习啦在线学习网 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!
学习啦在线学习网 I agree with you. This is a concern for many parents and
学习啦在线学习网 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
学习啦在线学习网 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.
学习啦在线学习网 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?
学习啦在线学习网 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.
