Germs（细菌） are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air! Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.

Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs. What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

举一反三

The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them.
But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless （无害的）thing.
Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired.
Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth.
Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again.
Perhaps these comets that never return have broken into pieces. For some astronomers think that shooting stars(流星) are pieces of broken comets.

Recent years , with the development of the computer and the Internet, many students often use computers to surf the Internet . Should students be allowed to surf the Internet? Here are some people’s opinions .
Tracy	I study in a junior high school . I think students shouldn’t be allowed to surf the Internet . Surfing the Internet wastes a lot of time , so the students spend less time doing their homework . Also many students lose themselves in playing the computer games . In their minds , games are everything and they keep on playing the games for hours . That’s too bad for their study and their health .
Jimmy	I don’t agree with Tracy . In my opinion , surfing the Internet can help us a lot . For example , I often get help from the Internet . I’m weak in learning English . When I have trouble in learning English, I can get on line to ask for help . Always I can get the answers soon . In this way , I have made great progress .Thanks to the Internet .
Jeff	Yes , I have the same opinion as Jimmy . My son , Bob studies very hard . After hours of working hard , he usually feels tired . If he goes on with his study , he will feel stressed out . So I often ask him to surf the Internet to listen to some light music . It can help him relax and he will study better later on .

Take a book and sit with your        toward the window, and try to read. Your shadow(影子) falls all over the page and makes it        for your eyes as if you were in a        room.
Now turn around and face the window. The page is        shadow again, while the bright light is in your eyes.
Try sitting with your        side toward the window. This is very good for        , but if you were writing, the shadow        fall across the page and bother you        .

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.
小题1:For a long time humans think ________.

A．they can surely find life on Mars

B．there may be life on Mars

C．it’s too late for them to explore Mars now

D．Mars is the only planet that has life on it

小题2:The two robots ________.

A．have found out that it is warm and wet on Mars

B．were sent to Mars to find some stones

C．were the first two American robots that landed on Mars

D．are the only machines that have landed on Mars so far

小题3:The third paragraph mainly tell us ________.

A．it’s a very hard and dangerous trip for spaceships to Mars

B．two-thirds of the spaceships sent to Mars have failed

C．Spirit and Opportunity landed on Mars successful

D．Mars is called the “death planet”

小题4:From this passage we learn that ________.

A．the two robots have found water on Mars

B．Opportunity touched on Mars a week later than Spirit

C．it’s exciting to have the chance to look for signs of life on Mars

D．Korabl was the first Russian machine to land on Mars

阅读下列短文，根据短文中的信息完成文后表格。（每空一词)
In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

The importance of 小题1: the environment
Problems	◆ More fish being caught. ◆ More 小题2: being cut down. ◆ More waste products being 小题3: into rivers. ◆ More 小题4: being born.
Causes	◆ The world is becoming too 小题5: . ◆ Modern methods make the situation 小题6: .
小题7:	We human beings will not survive on the earth.
Solutions	◆ Eat more vegetables and less meat so that more food will be 小题8: for everyone. ◆ Use modern methods of 小题9: control so that the population will not grow too fast. ◆ Educate people so that the 小题10: will be better and cleaner.
