Conversation Two

　　W: 【22】We're talking this hour about how and why people might become addicted to the Internet. Dr. James at Maryland University has put together a support group for students who find themselves addicted to the Internet. He joins me now from his office in College Park.

　　M: Thank you very much for inviting me.

　　W: Is Internet addiction a relatively new thing?

　　M: Well, some may have been addicted for a while.

　　W: How does it present itself?

　　M: Well, some of them have issues like relationship problems, or 【23】problems maintaining their grades because they are spending so much time on the Net.

　　W: But I think the computer is a very positive thing. How do I know when my impulse to go online will turn me into an Internet addict?

　　M: Uh...I'm not sure the exact amount of time is really the issue, 【24】but I think if it begins to affect other areas of your life, such as your work or school performance. One of the problems with the Internet, is that people start losing some of the skills that make relationships successful. If you are beginning to feel anxious or depressed or empty or lonely and you know you really look forward to those times when you can be online to be connected with other people in that way, then, a serious issue is starting to happen.

　　W: What if you start giving up other things, like going out for a walk...is that a symptom?

　　M: 【25】Well, I think it's helpful to have some sort of balance in your life. If you can, spend some time on the Internet and then go out and take a walk.

　　W: So that's how we can avoid Internet addiction. Thank you very much, Dr.James.

　　Section B

　　Passage One

　　The diamond is considered the most famous and valuable jewel in the world. A diamond is a symbol of wealth.

　　Diamonds were made as a result of great volcanic heat and pressure.A volcano is a mountain with a hole on the top. A volcano can be very dangerous because when it is active it sometimes explodes and causes great damage.

　　【26】Diamonds were pushed towards the surface of the earth—millions of years ago by a number of great volcanic explosions. 【27】It is in the narrow volcanic pipes that diamonds are found. They are also found among the sand and stones of certain river beds, and in a few places on the floor of the sea. For they were washed down the mountain sides by the rain.

　　【28】Diamonds are very rare. There are not many diamond pipes or diamond-producing rivers in the world.During the last century adventurers from Europe went to Brazil, because they had heard that there were diamonds in the River Amazon. Many of these early diamond miners died of illness or were lost forever in the great forests. But some returned home rich. They were lucky enough to enjoy their lives.

　　【28】 The earliest known diamonds were found in India many centuries ago. The most recent and exciting discoveries have been made in eastern Russia. But most of the world's diamonds now come from Congo, from Tanzania—which has the largest diamond mine in the world and from South Africa.

　　Questions 26 to 28 are based on the passage you have just heard.

　　26. Which of the following is mentioned by the speaker?

　　26. 答案C

　　解析：選項是關于鉆石出現的地方。聽力篇章一開始，講到鉆石的出現是因為火山爆發的熱量和壓力，接下來說，火山爆發把鉆石推向了地球表面。

　　27. According to the passage, where did diamonds first come into existence?

　　27. 答案A

　　解析：選項表示地點。聽力篇章接下來講，可以在火山縫隙中發現鉆石，也可在河床上發現。由此可以判斷A為正確選項。

　　28. What do you think is the best title for this passage?

　　28. 答案A

　　解析：從選項的拼寫方式，可以推斷問題可能是文章的題目。聽力篇章開篇講到鉆石形成的原因，接著講到鉆石出現的地方，最后提及鉆石量最多的地方。所以文章的主旨為鉆石的形成和發現。
