Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you're paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there's going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they'll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this.
The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It's actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven't expected launch costs to come down far enough to make them possible.
Lots of people who've been to space have described vividly what it's like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don't need to sleep much living in zero gravity, so you'll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.
Of course all good things have come to an end. Unfortunately, And so after a few days you'll find yourself heading back enough you'll be much more expert at exercising in zero gravity than you were when you arrived. You'll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel.

Alan took an early interest in gardening---first on his grandfather’s Yorkshire allotment in Ilkley, and then in his parents’ back garden. Small polythene（聚乙烯）greenhouses appeared in the back garden, and cacti（仙人掌）were bought from church markets.
Alan left school at fifteen with one `O’ level in Art and took a job as an apprentice（学徒）gardener in Ilkley Parks Department nursery, studying for his City and Guilds in Horticulture（园艺）in the evening.
He went on to horticultural college at Oaklands in Hertfordshire where he studied for one year full-time, being awarded the National Certificate in Horticultural. This was followed by three years at the Royal Botanic Gardens, Kew, resulting in the award of the Kew Diploma.
After two years as supervisor of staff training at Kew, Alan entered journalism where he became first a gardening books editor, and then Deputy Editor of Amateur Gardening magazine. He appeared regularly on BBC Radio and Television in programs such as Nationwide , Breakfast Time, Open Air, Pebble Mill, Songs of Praise, Titchmarsh’s Travels, and the Chelsea Flower Show. He presented the 100th edition of The Word for Channel 4, and hosted the quiz show Ask the Family.
Gardeners’ World and the hugely popular Ground Force, second only to Easterners in the BBC1 ratings, are broadcast as far as Australia, New Zealand and North America.

On November18, 1995, Itzhak Perlman, the world famous violinist, came on stage to give a concert at Lincoln Centre in New York City. If you have ever been to a Perlman concert, you know that getting on stage is not easy for him. He got polio（小儿麻痹症）as a child, and has to walk with the aid of two crutches（拐杖）now.
That night Perlman walked slowly to his chair. Then he sat down and began to play. But, suddenly, one of the strings on his violin broke. You could hear it break---it broke with a loud noise.
People thought to themselves, “He would have to get up to either find another violin or find another string for this one.”
But he didn’t. Instead, he waited a moment, closed his eyes and then signaled the conductor to begin again. The orchestra（管弦乐队）began, and he played from where he had stopped. He played with such passion and such power.
Of course, everyone knows that it is impossible to play a symphonic work with just three strings. But that night Itzhak Perlman refused to know that. You could see him changing and recomposing（重新作曲）the piece in his head.
When he finished, there was a silence in the room. Then people rose and cheered. We were all on our feet, doing everything we could to show how much we appreciated what he had done.
He smiled and then he said in a quiet tone, “You know, sometimes it is the artist’s task to find out how much music you can make with what you have left.”
His words have stayed in my mind ever since I heard them. That is also the way of life. Perhaps our task in this quickly changing world in which we live is to make music, at first with all that we have, and then, when that is no longer possible, to make music with what we have left.Holding a concert is challenging for Perlman because ______.

| C．Another performer would play instead. | D．The concert would be put off. |
The audience rose and cheered ______.
| A．to show they are satisfied with Perlman’s performance |
| B．to thank the orchestra for their passionate performance |

It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry.
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.According to the passage, which of the following statements is true?
| A．People of different ages are interested in different things |
| B．People in different countries are interested in different things. |
| C．Men and women are curious about different things. |
| D．People are curious in the same way. |
Scientists who work with the biological sciences study____.
| A．the earth , the oceans and the sky | B．plants and animals |
| C．man-made things | D．ocean water |
When you run, your muscles need ____.
| A．more nutrition and oxygen | B．more signals | C．more salt | D．water |
A rock cracks _____.
| A．in wet regions | B．in dry regions |
| C．at very high or very low temperatures | D．when salty water falls in |
People are always curious because ____.
| A．they cannot explain many things | B．they know nothing about the world |
| C．they know little about the world | D．they want to be scientists |
Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(证据) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑润的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．Which of the following is wrong?
| A．Coca’s chemicals can prevent both cell damage and inflammation. |
| B．Chocolate may help you lower your blood pressure. |
| C．People early know chocolate is good for their health. |
| D．chocolate may improve your memory, attention span, reaction time, and problem-solving. |
