Sydney-Mobile phone has become a problem for middle schools. Some middle schools in Australia have banned students from carrying mobile phones during school hours.

Mobile phone use among children has become a problem for the school this year. Several children have got mobile phones as Christmas gifts, and more students want them.

Mary Bluett, an official, said mobile phone use is a distraction (分心) to students during school hours and it also gives teachers so much trouble in their classrooms. Teachers were also saying that sometimes students might use phone messages to cheat during exams.

She said some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn’t get in touch with their children.

Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school offices. They also said there were many reasons why the students should not have mobile phones at school: they were easy to lose and were a distraction from studies.

Many people say that they understand why parents would want their children to have phones, but they think schools should let the students know when they can use their mobile phones.

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.　　　　　　　　　　　　　　　　　

Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he op­erated on them. He made the monkeys’ blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys’ brains. When the brain’s tempera­ture was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

PART THREE 　READING COMPREHENSION

Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage. (18 points)

　　　　　　　　　　　　　　　　　　 A

Even if you are a good high-jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity.

　　 You can easily find out the pull of the earth. If you weigh yourself, you will know how much gravity is pulling you.

　　 Since there is gravity, water runs down hill. When you throw a ball into the air, it falls back down. Because of gravity, you do not fall off the earth as it whirls (旋转) around.

　　 Then, can we get away from the earth and go far out into space? Now you can do it, because spaceships have been invented. Then spaceship will go so fast that it can escape the earth’s gravity and carry you into space.

Jane,

I was so excited to be picked to represent Canada. I have 　58　 　to Pompeii in Italy and am now in China 　59　 　Loulan. Both places were important commercial cities about 2,000 years ago. They　 60　 　disappeared and became lost civilizations. Pompeii was destroyed 　61　 　a volcano. It erupted and 　62　　 　Pompeii with ash. Loulan disappeared under the sand. No one is quite sure 　63　 . There are just a few ruins 　64　 . Some treasures, such as coins and painted pots, were found, and recently some bombs. I am becoming very 　65　 　in ancient civilizations. Maybe I shall become an archaeologist one day.

What do you think?

See you when I get back.
