As we know, it is not easy to build a satellite. Building a traditional satellite normally takes years. The
costs can be as high as $ 250 million or more. Most members of the design teams have worked in the field
for a long time. They hold advanced degrees in math, science, or engineering.
But things are changing. High costs, unusual educational requirements and long start-up times are no
longer an obstacle to space exploration. The scientists at Stanford University have developed a new type of
tiny, inexpensive earth-orbiting satellites that go from ideas to launch (发射) in a year.
So far, college students have built and launched several cube-shaped satellites, or Cube Sats. At least 15
more are ready to go. Those already in orbit (轨道) take pictures, collect information. and send it back to the
earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own
satellite. A new program called Katy Sat aims to get teenagers to take part. Once kids understand and what
satellites can do, says Ben Yuan, an engineer at Lockheed Martin in Menlo Park, Calif, the kinds of applications
they"ll come up with may be countless.
"We"d like to put this technology (技术) in your hands," he tells kids." We"re going to teach you how to
operate a satellite. Then we want to turn it over to you as a sandbox for you to play in. We want you to take
the technology into new directions that we haven"t though of yet."
Education isn"t the only goal of Cube Sats. Because these tiny, technology-filled boxes are relatively
inexpensive to build and can be put together quickly, they"re perfect for testing new technologies that might
one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two.
Otherwise, major highways of space junk could gradually increase as CubeSats become more common.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space.
Someday-perhaps a lot sooner than you imagine-you might get to design, build and launch your own satellite.
If you do, you"re sure to have fun. And you might also get crazy a-bout science for life.
B. are low-cost and small-sized
C. are very hard to operate
D. collect more information in orbit
B. An imagination that kids usually have.
C. Something dangerous to terrify people.
D. Something difficult that stands in the way.
B. A few kids will send applications for the project.
C. Scientists designed CubeSats for kids to play with
D. Students can"t design satellites without college education.
B. To show that kids lead the space research into a new direction.
C. To tell us that satellite technology can also be learned by kids.
D. To tell us that kids must study hard to learn satellite technology.

For many years, doctors have been studying the way the brain 2 . We all know that the brain has two
sides, the left and the right. The right side controls the senses and the left side of our brain controls our
logical 3 . We call the left side the "education" side of the brain, and generally, in western countries, people
have 4 this side of the brain more than the right side.
Scientists believe that our brain will work more efficiently if both the right side and the left side are
developed equally. In many schools today, teachers try to educate children in such a way that both sides of
the brain are 5 . This can be done with logical subjects 6 math and science as well as with creative subjects
such as art. Albert Einstein, the great scientist, did some of his best work when he was very old. He was 7

| This is the times of information technology. Pakistan (巴基斯坦) is also trying to keep up with this IT development and special steps are being taken to spread the Internet all over the country. This is considered as a great achievement and it is. But here is a question whether our people know the use of the Internet for development purpose. It is a fact that the ratio (比率) of informative and educational sites is very low. What do many of them do in Pakistan when people surf the Internet? They use it mostly for entertainment. Many students spend a lot of time and money in surfing the Internet. They do chatting or visit other entertainment sites. It is surprising to read that boys and girls go to the Internet cafes and spend many hours daily in just chatting. just join any Pakistani chat room at any site, and you will know that what is the level (水平) of language and which type of language mostly our people use in chatting. The number of the web addicts in our country is increasing day by day. It is also a fact that many people including teenagers visit sites unsuitable. One can imagine that they are becoming worse and they are becoming addicted to such things that are very harmful (有害的) to them. They are taking all the disadvantages from the Internet. Students do use the Internet for education purpose. But there are also several disadvantages. Students normally surf more on the Internet than teachers. It happens several times that a teacher gives some work to students and they get it from the Internet, copy it and present it to the teacher, who many times is unable to know what is copied from the Internet. In this way students are giving up the habit of reading books. They just open sites, copy the information and finish the homework that they do not even read. However, a very good advantage of the Internet for students is that those who want to seek knowledge can get information very quickly and read many books by famous foreign authors which are very expensive to buy. The Internet itself is a very useful and important tool of development nowadays, but it is really sad that in Pakistan people are mostly misusing it. Those who use it for development purpose are still very few. | |||

| It"s 2009. You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks what you"ve been thinking about lately. When you leave, she gives you some medicine, but also a list of thinking skills that you are supposed to practice daily. She says that the way you think is causing some of your illness. Doctors and other scientists who study the human mind and try to explain why people behave in the way that they do, called psychologists, are starting to believe it. You know that your brain is connected to every part of your body through your nervous system (神经系统). Now scientists have proved that how you think and feel can have an influence on the health of your body. Stress (压力, 紧张) is caused whenever there is a problem or a change in your life. Of course, everybody has stress more or less; nobody"s life is perfect. In fact, stress is necessary. Without stress, we would never learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you. It can weaken your body"s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident. When you feel stress, your brain sends a message to your body to produce a chemical called adrenaline (肾 上腺素) . Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress. Problems like endless homework or troubles with your family are the kind of things you can"t fight or run away from, so you don"t use up all that adrenaline.lt just stays bottled up inside you, and that"s what can do something bad to you. What can you do about stress? First, you can try to find ways to change things so you aren"t under so much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out with your family or your friends. But sometimes you can"t change a stressful situation. Sometimes you don"t even want to. A big change might be a good change, but it will still be stressful. The link (关联) between your body and brain works in two ways. Your body can help your mind deal with stress. If you are under stress, you need to take especially good care of your body. It"s important to get enough sleep and eat nutritious meals. Some people take a vitamin-mineral pill every day. Another thing that you can do is daily exercise, If you go walking or do aerobic dancing or work out at the gym, you give your body a chance to burn up some of that adrenaline. Of course, a person who isn"t used to much physical activity should start slowly. Anyone with a continuing physical problem should check with a doctor before starting any exercise programs. | |||

| Here are some suggestions on listening. We hope they can help you in one way or another. ●Relax yourself Before you start to listen to something, you need to relax. Don"t get nervous or excited. This will help you with your listening. ●Listen carefully to the first sentence The first sentence tells a lot about the whole passage. For example, if, at the very beginning, you hear "Many shops in many parts of China have decided to take away all kinds of Japanese goods off their shelves, but some people say it"s not a good idea. Our reporter says…", you know you will hear a piece of news, not a children"s story, or a science report. ●Think when you"re listening When you"re listening, try to do some thinking. For example, you can think of the following questions: What happened? When, where, and how? What was the result and what did the speaker want to tell us? In this way, you may understand the passage better. ● Listen to important facts It"s important for you to remember some important facts. For example, if the passage is a science report, you should try to remember its findings, and how the scientists got their results. This is also helpful to your listening. | |||
