Zhou got his mobile phone five months ago. He sent messages to his friends with it all the time, even when going to bed. Zhou started to do badly in the exams because he spent so much time playing with his mobile phone. His mother got very angry with him. He didn’t stop playing with the mobile phone until his arms got injured.
Yang Ling,a doctor, says that if someone uses his mobile phone too much, like Zhou Yan, he might get “mobile phone disease’. If teenagers find their arms or fingers hurt, they should go to see a doctor as soon as possible. Yang Ling said students should try to use their mobile phones less,especially at school.

When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called " blood transfusion（输血）". The blood goes from the arm of the healthy person into the arm of the sick person.
But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups—O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.
There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.
We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you.

| A．give the right kind of blood to the people who need it in time |
| B．keep different groups of blood as much as possible |
| C．make it easier to sell or buy blood |
| D．keep blood for more than twenty hundred years |
| A．the writer thinks it"s good to give blood to a "blood bank" |
| B．we may become ill if we give blood to a "blood bank" |
| C．there are many blood banks in the world today. |
| D．blood is more important than money |
| A．how important blood is to us | B．the four groups of blood |

All the animals and plants need air. Living things can’t live without air. We can live without food or water for a few days, but we can not live for more than a few minutes without air. We breathe in air. When we are walking or running, we need more air. When we are asleep, we need less air.
We live in air, but we can’t see it. We can only feel it. We can feel it when it is moving. Moving air is called wind. How can we make air move? Here is one way. Hold and open a book in you hand in front of your face. Close it quickly! What you feel is the air.

What do they eat?
Scientists don’t have many choices on what they eat. About 60% their food is frozen food. It is easy to heat﹙加热﹚。Meat is common on the menu, while vegetables are not usual. Fresh vegetables are hard to grow in the cold weather. Therefore, people often eat dried and canned vegetables.
How do they sleep?
In Antarctica, summer lasts from November to March. During this time, Antarctica faces the sun and gets sunlight 24 hours of the day. In order to get some sleep,scientists cover the window with black cloth to make “night”.
How do they work?
People can wear warm clothes to be against the cold weather, but they can do little with the strong wind. Sometimes, the wind is even stronger than a typhoon. It can easily blow people away.
So there are ropes﹙绳索﹚that connect some research stations. People can hold these ropes to keep balance in strong winds.
How do they keep in touch with others?
There are no cables or Internet on the frozen continent. So mobiles and computers don’t work there. Scientists usually use two-way radios to communicate at work. If they want to say hello to family and friends, they can use the satellite phones.
小题1:What do scientists do in Antarctica?
| A．They mostly study on the animals and plants there. |
| B．They mostly find resources and study climate change and sea biology. |
| C．They mostly find different kinds of lives under the ice and study them. |

When Captain James Cook traveled around Antarctica in the 1770s by ship, he found no one living there. Today, a few scientists work in Antarctica, but they only spend a short time there.
Many scientists are studying the ozone layer, which is getting thinner and thinner worldwide. The biggest “hole” is above Antarctica, and weather there is getting warmer. Scientists think that this cold and lonely place can teach us a lot about the earth and how to keep the earth safe.
小题1:When did Captain James Cook travel around Antarctica?
| A．In the 1670s. | B．In the 1760s. | C．In the 1770s. | D．In the 1780s. |
| A．冻土层 | B．大气层 | C．臭氧层 | D．高压层 |
| A．Two. | B．Three. | C．Four. | D．Five. |
| A．Antarctica is much bigger than Australia in size. |
| B．Scientists spend a long time in Antarctica. |
| C．There is no plant growing in Antarctica. |
| D．In winter, it’s dark for about 70 days in Antarctica. |
| A．Because there are more and more people living there. |
