A single rocket has not enough power to launch (发射) a satellite, but two or three rockets can do this work.
Let us see how a three-stage rocket work. The first stage forms the tail; the second stage is in the middle; and the third stage is in front. The satellite sits in the nose of the third stage. Each stage has its own engines. The first stage is used for driving the rocket at the time of launching. It lifts the rocket into the sky. After a few minutes the first stage burns out and falls away. The engines of the second stage then drives the rocket. Later this stage burns out and falls away, and the weight of course gets lighter. As a result, the rocket travels faster. So it gains enough speed to break away from the earth's pull. When the last engine burns out, the launching is successfully ended. The satellite now travels in space by its own speed.
1.Launching a satellite can be done at least by ________.
[ ]
2.The farther a satellite travels from the earth, ________.
[ ]
A.the slower it will fly in the sky
B.the heavier its weight will become
C.the greater the pull of the earth will get
D.the weaker the pull of the earth will get
3.Which of the following is TRUE about the satellite?
[ ]
A.The first stage forms the tail.
B.It connects with the second stage.
C.It can drive the rocket out of the earth.
D.It sits on the ground before being launched.
4.From the passage we know that ________.
[ ]
A.a satellite will weigh little or nothing in space
B.a satellite will fly faster and faster in space
C.the third stage is the most important to a satellite
D.a satellite gains enough speed before the second stage falls
5.The best title for this passage should be ________.

Life in space will certainly take some getting used to!But the space station has been designed to keep the astronauts as comfortable as possible—the modules(舱) are roomy,bright,and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday,crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals,and 8.5 hours sleeping.Here are some other fun facts about life aboard the station:
Food
Come mealtime,astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions,astronauts could eat only freeze?dried food that didn’t require any preparation.But the space station is equipped with water,microwave ovens,and refrigerators,allowing the folks on board to eat more “normal” types of food,including fruit,vegetables,and ice cream!
Sleep
Each crew member has a private room.With no gravity,they’ll need to tie themselves to their beds,or they will float away!That might sound like a strange way to sleep,but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it,but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up,sit down or walk in space,so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this,astronauts on the station will exercise on bikes,rowing machines,and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U.S.shuttle or Russian rockets.But once they’re safe inside the space station,crew members can wear regular clothing.Of course,a specially designed,pressurized space suit is required for space walks.It has to withstand(经受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble!Astronauts will use a freshwater hose(软管) to take showers,shampoo,and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space?With a special “air toilet” that uses flowing air instead of water to dispose of waste.
1.The facts about life in space are all mentioned EXCEPT ________.
A.clothing? B.entertainment
C.sleep? D.exercise
2.What can be learned from the paragraph “Clothing”?
A.The temperature is quite different in different places in space.
B.Astronauts must wear special space suits all the time in space.
C.Astronauts can wear regular clothing for space walks now.
D.Astronauts wear pressurized space suits just to keep warm.
3.Why is exercise more important in space than on earth?
A.It can make astronauts feel relaxed in space.
B.It can help astronauts spend their spare time happily.
C.Astronauts’ lives are more important in space than on earth.
D.It can prevent astronauts from causing muscle and bone loss.
4.What do we know about space food from the text?
A.Astronauts could eat apples in space in the past.
B.Astronauts eat only fruit,vegetables and ice cream now.
C.Fresh food isn’t available to astronauts in space.
D.Space food is getting better now than before.

Is war unavoidable? Can war be prevented?
History tells that there were wars, great or small, in every century, in every decade. Throughout the ages, from the Stone age to the Atomic Age, men have been fighting, first with swords and shields(盾), then with guns and cannons, and now, hydrogen bombs and missiles are used for military purpose. But, in spite of all these, it is still my belief that war can be prevented and peace can be won, but it requires the effort of every one of us.
I am sure that we would not like to experience another world war. If it ever happens, two-thirds of the world and much of the civilization which men have gained through time, patience and effort will be destroyed. Will then the remaining one-third of the world be able to survive on its own?
Our task now is not to blame the past, but to plan for the future.
If there is peace in the world, men can use their rockets to explore the mystery of space, their submarines to explore the depth of the sea, their missiles to deliver mails and their fine equipment to penetrate(穿透) the jungles of Africa, instead of using them military.
Governments can use their money to build more schools, so that more children can be educated to be useful citizens. Scientists can use atomic energy to propel (推动) steamships and planes. They can also design new machines to increase the production of goods and thus improve the way of living of the people.
How can a peaceful world be achieved? It requires, in my opinion, the understanding and friendship between all people from all nations. Let no one suffer discrimination by reason of color, race, religion, or national origin. Let the rich support the poor and the strong help the weak.
We know that neither peace nor such a dream world can come true in a day or a month. It may even take decades or centuries. But let us plan and begin now.

In the past ten years, America’s National Basketball Association (NBA) has grown increasingly dependent on the rest of the world to supply players.
When Michael Jordan and Larry Bird won gold in Barcelona in 1992, the Americans were praised for teaching the world how to play basketball. This season, however, 20 percent of NBA rosters① will be filled by non-Americans. NBA commissioner David Stem happily embraces the trend. On a visit to Paris in October, Stern outlined his vision for the future, which is likely to see Europe hosting NBA games by 2010.
The NBA is now planning to take China by storm.
“Our experience in China has been that it is going to be explosive in its growth,” said Stern. The strategy② in China is television. “We’ve made 14 deals in China with local and national networks on cable and satellite.” The success of Chinese centre Yao Ming has paved the way for the NBA marketing blitz in China. The NBA, which is broadcasted in more than 200 countries in 42 languages, will put that to the test in October 2004 when the Houston Rockets play two pre-season games against the Sacramento Kings in Beijing and Shanghai. The NBA knows that it needs a global market to compensate for tough times on home soil.
“It doesn’t matter where the players come from, all the NBA teams now know that they have to scout③ internationally,” said Terry Lyons, the NBA’s vice-president of international public relations. “It has increased the level of competition here.” As Frenchman Tony Parker and Argentine Emanuel Ginobili showed in winning championship rings with the San Antonio Spurs last season, many people can earn the respect of their American peers. Others, such as the Houston Rockets’ Chinese centre Yao Ming — number one draft pick in 2002 — and the Detroit Pistons’ 18-year-old Serb Darko Milicic — number two overall in this year’s draft — are icons④in-waiting. It is the ultimate⑤ revolution — the rest of the world teaching the US how to play basketball.
Notes:
roster n. 花名册
strategy n. 战略,策略
scout vt. 寻找,觅得
icon n. 偶像
ultimate adj. 最后的,根本的
