Elvis Presley,who was one of the most popular American singers of the twentieth century, made the Rock & Roll music popular around the world. He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.

Elvis Presley was born in a poor family in 1935. His parents were simple country people who often took him to church, where he learned to sing and he never forgot the kind of songs that he used to sing in church as a child.

When he was a teenager, Elvis moved from Tupelos to Memphis in Tennessee, where he attended high school, but he was not a good student. His only real interest was singing. He began to sing in the style that is called “country and western”.

In 1955 he recorded some songs for his mother's birthday. The people at the recording studio liked his singing and his music. There was something different about it. It was country and western music, but it also sounded a little like the music, which black people used to sing in the American South, music known as “blues”.

Shortly after that, Elvis met Tom Parker, who became his manager and arranged(安排)concerts for him across the United States and new recordings as well. Soon Elvis rose to fame all over the country. Later, Elvis went to Hollywood and began to appear in films like Love Me Tender and King Creole.

But Elvis found it hard to live with success, like many other entertainment personalities (娱乐圈内的人士) .He began to take drugs and his health began to suffer. When he died at an early age of 42 in 1977, his many millions of fans were shocked. “The King Is Dead!” the newspaper said. But today his memory and his music live on and he will always be remembered as the King of Rock & Roll.

When I was at school,our teacher often said,“You are what you eat.”She wanted us to eat the right food to be healthy.

Japanese people are said to be the healthiest in the world.They eat rice,fish and vegetables every day.They drink green tea or water when they’re thirsty,and snack on dried fish,fruit or nuts.So we can believe that you become what you eat.When you know the advantages of different kinds of food,you can use your knowledge well and eat what you want to become.

Have you ever heard any of the following advice?

*Lettuce or milk can make you sleepy while peanuts or dried fish will stop that feeling.

*To keep your teeth clean,you should eat apples often.

*Garlic(大蒜)helps to prevent colds.

Future restaurants might be named after what they hope to create.Let’s take the restaurant“Winners”as an example.Its menu would list dishes specifically designed to help you win sports games.There would be rich tomato sauce(调味汁)full of vitamin C and soft vegetables.All this would have a little fresh cheese on the top—just enough to help you get a good night’s sleep.

What will happen to junk food in the future?If ice cream is not good for children,can’t we give them fat-free,sugar-free tofu ice cream?We are told dried fruit is a healthier snack than biscuits,so some biscuit companies are making biscuits with more vitamins.So in the future,you might be able to eat your way to health!

The oddness of life in space never quite goes away. Here are some examples.

First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”

On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.

Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks you’re falling. Meanwhile your eyes are telling you you’re standing straight. That can be annoying—that’s why some people feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.

Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.

28.What is the major challenge to astronauts when they sleep in space?

   A. Seeking a way to fall asleep quickly

   B. Choosing a comfortable sleeping bag

   C. Deciding on a proper sleep position

   D. Finding a right time to go to sleep.

29.The astronauts will suffer from a carbon-dioxide headache when _____.

   A. the y circle around on their bikes

   B. they use microcomputers without a stop

   C. they watch a movie while pedaling

   D. they exercise in one place for a long time

30.Some astronauts feel sick on the station during the first few days because _____.

   A. their senses stop working

   B. their brains receive contradictory (矛盾的）messages.

   C. they float out of their seats unexpectedly

   D.they have to stand up straight

31.One of the NASA’s major concerns about astronauts is _____.

   A. how much exercise they do on the station

   B. how they can remain healthy for long in space

   C. whether they can recover after returning home

   D. whether they are able to go back to the station

   For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.

    “A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts.

    These parts are not made of steel; they are the real things --- living cells, tissue, and even organs.Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina’s Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs 一 from kidneys to ears.

    The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient’s body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient’s own cells and will not be rejected by the body’s immune system.

    Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala’s medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.

    So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals’ chances of survival.

32. In the latest field of regenerative medicine, what are replacement parts made of?

   A. Donated cells, tissues and organs.

   B. Rejected cells, tissues and organs.

   C. Cells, tissues and organs of one’s own.

   D. Cells, tissues and organs made of steel.

33. What have scientists experimented successfully on for a bioartificial kidney?

   A. Patients.     B. Rats.     C. Sheep.     D. Soldiers.

34. Why is generative medicine considered innovative?

   A. It will provide patients with replacement soft tissues.

   B. It will strengthen the human body’s immune system.

   C. It will shorten the time patients waiting for a donated organ.

   D. It will make patients live longer with bioartificial organs.

35. What is the writer’s attitude towards regenerative medicine?

   A. Positive.      B. Negative.         C. Doubtful.          D. Reserved.

    In your life, sometimes you may be asked to speak in front of a large group of people. Although it sounds a little scary, even those with stage fright can speak successfully to the group with adequate preparation.

 1. Practice your speech before the big day.   36    If possible, practice the speech in front of a friend or family member to get used to saying it to real people. If you feel you must have note cards, limit the amount to about three cards. This will force you to keep your speech concise and help you keep your eyes focused on your audience.

 2. Remember why you've been invited to speak. If you're battling fear over speaking to a large group of people, keep your mind on the fact that you were selected for this important role. The speech organizers must have seen something valuable in you or your expertise.    37   .

 3. Remember that fear of public speaking is very common.   38    Most of the people in the audience would be feeling the same fear and stress that you do in your position. Knowing this may make you feel better.

 4.   39   What you say should be tailored to why you're there and who you're speaking to in order to avoid sounding general. If speaking to a charity group, mention the good work certain specific individuals have done for the cause. If speaking at a business conference, briefly state why you want to help these people.

 5. Keep eye contact with the crowd.  40   Pick one person in each section and look at him while you're speaking. After each important point in your speech, switch your focus to another section. When you focus only on one person at a time, the size of the crowd isn't as frightening.

A. A good memory is really helpful.

B. Show appreciation to your audience.

C. Mention your audience in your speech.

D. The more you have it memorized, the better.

E. In fact, it's normal to feel nervous or stressed out before a big speech.

F. Separate the crowd into three sections mentally as you get up to speak.

G. The knowledge of other people's respect for you should reduce some of the fear.
