举一反三
When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong!
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.

Air is always around us. It is around us when we walk and play. From the time we are born, air is around us. When we sit down, it is around us. When we go to bed, air is also around us. We live in air.
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.

There are seven continents﹙洲﹚in the world. Among them, Antarctica﹙南极洲﹚is the most special one. It is a world of snow and ice all year round. China has sent many scientists there. They try to find resources﹙资源﹚under the icy land and study climate change and sea biology.
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. | | D．They mostly study on the ice and geography. |
小题2:What kind of vegetables do they usually eat?| A．Fresh vegetables | | B．Green vegetables only | | C．Dried and canned vegetables | | D．They go down the ice to work. |
小题3:What do they do when the day lasts for 24 hours?| A．They work all day long. | | B．They find a way to make “night”. | | C．They stop working on those days. | | D．They go down the ice to work. |
小题4:How do the scientists work on the terrible windy days?| A．They use ropes to help themselves. | | B．They just stay in the houses. | | C．They use cars and ships to help. | | D．They don’t think the wind brings trouble. |
小题5:If scientist wants to say “I love you”to her daughter, what can she use?| A．Mobile phones | B．Tow-way radios | C．Satellite phones | D．Iphones and Ipods. |

Antarctica is in the most southern part of the world. It is like nowhere else on the earth. It is much larger than Europe, and nearly twice the size of Australia. Antarctica is the coldest and windiest place in the world, even colder and windier than the North Pole. In summer, the sun shines for twenty-four hours a day, but in winter it’s completely dark for about three months. Very few plants grow there, but there is some wildlife, including whales, seals and penguins.
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. |
小题2:The underlined part “ozone layer” means “________” in Chinese.小题3:How many kinds of animals are mentioned in the passage?| A．Two. | B．Three. | C．Four. | D．Five. |

小题5:Why is the weather in Antarctica getting warmer and warmer?| A．Because there are more and more people living there. | | B．Because the ozone layer is being destroyed. | | C．Because the sun shines a long time every day there. | | D．Because the weather in other places is getting warmer. |

Many animals hide(躲藏) to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes(形状) help protect them. It’s hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons(变色龙) can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes.
Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary(可怕的). Some animals will run away from them.
Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger.
