What’s the red star in the sky through a telescope(望遠鏡)? It is Mars. Do you want to know more about it? Take the “Mars Orbit Express”!
“Mars Orbit Express” is a space probe (探測器). It was sent towards Mars by American scientists on August 12th，2005. Its tasks are to study Mars’ atmosphere and return photos to Earth. But before that “Mars Orbit Express” must travel about 100 hundred million kilometers and seven months. It reached Mars’ orbit(軌道)in March，2006.
Mars and Earth have similar weight and size. However，Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50℃. The temperature at noon only reaches 20℃ during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos.
Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives，Mars becomes bad. “Earth easily could have turned out like that.” said an scientist, “It is important for us to find out why and Mars Orbit Express’ should do that.” “Mars Orbit Express” also would help scientists to learn what might happen to Earth in the future.  “Mars Orbit Express” would work for about four years.

There are few families in the United States that do not have either a radio or television set. Both of them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with singing, dancing and acting.
Marconl, the Italian inventor, who gave us the radio, probably didn’t know how much his great invention would have done for the world in the years to come. Radio had, perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happen. Travelers in or out of–the–way places, ships at sea even astronauts round the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since its appearance, TV has done a great deal in the daily life of people everywhere. Many programs are now televised in color.
Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch on TV a motor–car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

Have you ever stayed in a hotel? Most Chinese hotels often provide guests(客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don’t have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.
Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources (資源) and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.
Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life:  Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school dining-room, use your own bowl and chopsticks instead of disposable ones.
To protect our environment and our home, it is very necessary and important for us to save natural resources.
(  ) 11. Why do many hotels provide guests with some disposable things?
A. Let their guests be convenient during their traveling.
B. Hope their guests use less disposable things.
C. Wish their guests to save money.
D. Want their guests to use more disposable things.

For several years, Americans have enjoyed teleshopping—watching TV and buying things by phone.Now teleshopping is starting in Europe (歐洲).In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.
Teleshopping is becoming popular in Sweden, for example.The biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made ＄100 million.In France there are two teleshopping channels, and the French spend about ＄20 million a year to buy things through these channels.

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic（遺傳的） material. Foods from plants grown in this way are called genetically modified(改變的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.

Many people think sports are just for winning and honor, but there is a lot more you can gain from (get out of) them. I have learned over the past years that sometimes when I lose, I get a lot more out of it than winning. Also, I find a lot of times in sports, people are getting too caught up in the game instead of just having fun. The real purpose of sports is to have fun and learn life lessons along the way.
I greatly encourage you to be a part of the school sports. Even if you are not the best, you can still have fun. Sports give people a great and healthy way of spending an afternoon, instead of lying around playing video games or even getting into bad things. Sports also give us a sense of achievement. There isn’t a better feeling than to have done something fun and productive for my day.
I think that we all need sports to give us courage. If we try hard in sports, we usually do well. If we did the same in study, we would all be champions. Another reason why I encourage you to play sports is that it’s just fun. Without sports, our lives would just be boring. So as you may be able to tell, sports are amazing!
Our coaches not only teach us to play sports, but show class and good sportsmanship while playing them. It’s never fun when you lose to have the competitor rub it in your face. That’s why our coaches teach us to show class when we lose; also, when coaches get onto you, don’t get down. They only want to see you improve and learn from what they say. When you do badly and they don’t shout loudly is when you should start worrying because they are giving up on you.
Overall, sports are great! They bring out the best and worst of a lot of us. However, we can’ t let sports get too serious to where it brings down all the fun. So to have the most fun in sports, you just need try your best and not worry so much about the winning or losing.
小題1:The underlined phrase “get onto you” in Paragraph 4 probably means ________.
A．point out your mistakesB．take up your time
C．worry about your future D．look into your privacy
小題2:Which of the following statements is TRUE according to the passage?
A．Sports bring us great fun only if we have the talent.
B．Sports give us the best way of spending free time.
C．We can get more out of winning than losing.
D．We should take pleasure in doing sports.
小題3:What is the best title of this passage?
A．Are we too caught up?B．To win or to gain?
C．Are sports really great?D．For honor or for health?

In the United States, children start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they leave secondary（中等的） schools. There are two kinds of schools in the United States: public schools and private（私立的）schools . Most children go to public schools. Their parents do not have to pay for their education because the schools receive money from the government. If a child goes to a private school, his parents have to get enough money for his schooling. Some parents still prefer private schools, though they are much more expensive. Today about half of the high school students go to universities after they finish the secondary school. A student at state university does not have to pay very much if his parents live in that state. But many students work while they are studying at universities. In this way they develop good working habits and live by their own hands.
小題1: Children can go to school at the age of four in the U.S.
小題2:Most parents prefer to send their children to private schools in America.
小題3:About fifty percent of high school students can go on to universities after they leave the secondary school today.
小題4:Lots of American students go to universities by depending on their parents completely (完全地).
小題5:The passage is mainly about American education.

Experts(專家) say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger (手指) with his eyes still closed, begging(請求) for one more minute to sleep. Like thousands of students “ early birds” in China, he has to get up before six every morning.
A report shows that without a good night’s sleep, students seem to be weaker (虛弱) than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
