The modem Olympic Games were founded with the intention of improving health and education, promoting world peace and encouraging fair and equal competition. But over the years, the Olympic saying, “Faster, higher, stronger”, has pushed scientists as well as athletes to do everything possible to reach new levels.
Doctors, engineers and coaches all use everything science can offer to achieve that little bit extra in competition. The reason modern technology has become part of sport is very simple: Winning is just as important as it was 2,500 years ago at the Olympics of ancient Greece.
Development in technology has often been reflected in the methods of training and performance used at the Olympics through history. This technology falls into two main groups: improving an athlete’s performance in competition, and allowing results to be measured more accurately.
One of the creations that have drawn the most attention is the new high-tech swimsuit from Speedo, which was used by most US swimmers in Athens. Until Sydney 2000, it was thought that the smaller the swimsuit, the faster the swimmer would travel.
“However, the fact that at the Sydney Olympics, 28 of the 33 gold medallists were wearing the body covering Fastskin suit proved the theory was out of date,” said Andy Thomas, vice-president of Speedo.
The company’s full body suit is supposed to make swimmers 3 to 4 percent faster, particularly when turning or diving into the water. It is believed that the suit creates less water resistance as it moves, behaving more like a shark skin than a human skin.
The introduction of high-tech equipment means that athletes in all sports, from the 100-metre sprint(短跑) to the pole vault(撑杆跳高), can now train more effectively and nourish (给…以营养) their bodies better.
Meanwhile, scientific development also means performances can be measured and studied far more accurately. Not only are winning times more accurately recorded, but cheating athletes are also easier to catch out. According to International Olympic Committee (IOC) requirements, two independent measuring systems should be used at all venues(比赛地点). Athens 2004 organizers used only the very latest equipment to measure distance and speed.
| The (1)_____ | The (3)______ | |||

| Science can (4)_______ athletes’ performance. | Science can get results (8)______ more accurately. | ||
| Winning is the most (2)_____ thing. | High—tech swimsuit from Speedo can make swimmers 3 to 4 percent faster and was (5)______ by 28 of the 33 gold medal (6)______ at the Sydney Olympics. | Athletes in all sports can train in a more effective (7)_______ | Winning times can be (9)_______ more accurately. | Cheating athletes can be (10)_______ caught out. |

The American cowboy was a great national hero through facts and stories.
In history, the real cowboy was a simple farm worker on horseback. He spent twelve to fourteen hours a day outdoors working with cows. The work was dirty, tiresome and not very well paid. In winter, most cowboys had to find other jobs. They were seldom alone. Most of them worked in teams of eight to ten.
People could raise beef cattle at low cost in the western states and send them by train to the eastern markets. Hut someone had to look after the cattle on the open land and get them to the nearest railroad . This was the job of a cowboy. Sometimes the railroad was more than a thousand kilometers away and it could take as long as six months to move the cattle. The cowboy moved the cattle slowly so that the cattle would not lose weight.
Most cowboys were young, unmarried men. A cowboy's horse was his most important tool. A good horse made the job of moving cattle much easier. A good cowboy understood cows and knew how to control them. At night, he sang to the cows to keep them calm .
The cowboy quickly received popular praise. Historians say that was because the cowboy appeared during a time of change in American life. In the late 1800's, America was changing from a nation of farms to one of factories and cities. The cowboy seemed free and more independent than other Americans.
Today, the life of real cowboys has changed greatly. One change has been the use of trucks. There is no need for the modem cowboy to sleep on the ground. Modem cowboys are better paid. They are likely to be married. Today cowboys are found in almost every state of the United States . Some of them are farmers or teaches or truck drivers . Some work for big companies. But at night and on weekends they became cowboys. Most have less than a thousand cows, and some have only two or three, those part-time cowboys increase the total production of meat, keeping beef price low. Most modem cowboys do not make much money from raising cattle. Many do it because they love the cowboy life.
1．In the past, the cowboy's work ________.
[ ]
A．was covered with dirt
B．cost much labor
C．was less paid
D．all of the above
2．Sometimes it took the cowboys ________ to move the beef cattle from the western states to the eastern markets.
[ ]
3．The cowboy's important instrument in the past was the ________.
[ ]
4．The cowboys quickly received popular praise because they appeared ________.
[ ]
A．in the western parts of the United States
B．in the eastern markets every year
C．in the time of great changes in America
D．in the early 1800's
5．Which of the following statements is true?
[ ]
A．The modem cowboys not only use their horses but also their trucks.
B．The modern cowboys still have to sleep on the ground outdoors.
C．The modern cowboys are badly paid.
D．Most modern cowboys don't love their work.

Today, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板）.Riders moved it by pushing their feet against the ground.
In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.
In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a velocipede，but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the velocipede was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.
Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient，and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy，and ridden mostly for entertainment.
It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893，the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.

You're rushing to get out of the door for a meeting, but you just can't seem to find your car keys. Or you've got tickets booked for a Caribbean cruise(坐船旅行) , but your passport disappeared. Or maybe you've just come back from a grocery store tour and realized…Hey, did I leave my baby in the checkout line?
Ok, you've probably never gone to the extremes of our last example (we hope), but most of us experience slip - ups like these on a daily basis. No matter how smart you may be, it doesn't mean your brain won't turn to Swiss cheese every so often, and no amount of e-mail reminders can help you remember where you left your TV remote or lucky penny.
But now, there is a new pair of eyeglasses that can help to find all those little things you know must be around somewhere : Let's call it Vision 2.0.
The new glasses, which are being developed in a Japanese lab under the code name Smart Goggles,are similar to a Google search engine for your eyes. The high - tech glasses come with a camera that records everything you see on a daily basis, and boast built - in object recognition software that allows them to keep track of whatever comes across their field of vision. If you've got a collection of art sculptures that the camera can't recognize immediately, no problem : Just say the name of each item, and the glasses will memorize them right away.
The Smart Goggles' superb tracking abilities mean that whenever you're looking for your keys, your overdue library book, or yes, even your baby, all you have to do is to say the word and the Goggles' camera will show you the last time your desired object appeared on screen, telling exactly where you'll be able to find it.
Though the glasses are still too big for general use, the research team in Japan believes that they'll be able to make the modem glasses smaller to the size of normal glasses in the near future, making them the perfect new accessory for yourself or any other absent - minded Professor you know.
With these intelligent designs, you'll never lose anything again. Except maybe your glasses.

Can feeling of nostalgia(怀旧) be good for you? Or is it unhealthy to have a strong love for the past?
For years, medical experts have studied nostalgia and the reasons for it. Many experts warn that too much nostalgia is harmful. They say living in the past shows that a person is unhappy with his present life. These feelings keep the person from living his life to its fullest.
However, experts say it is normal to love the past sometimes. In fact, a little nostalgia can enrich a person’s life.
Dr. Louise Kaplan has written several books about nostalgia. She says these feelings often begin when a young person is between 13 and 19 years old.
“This is the time when you must face the loss of your childhood, “Kaplan says. “You see your new life is easily destroyed. But you think romantically about a golden past. You remember your childhood as a time when life is perfect.”
These feelings continue as the person gets older, Kaplan adds. She says many grown persons have a hard time keeping up with changes in the modem world, so they think back to their younger years. At that time the world seemed simple and more harmless.
Kaplan says these feelings do not always actually exist. The good old days did not always exist. The good old days weren’t always good. However, she says nostalgia can be helpful, if used properly.
“Feelings of nostalgia can cause you to remember a time when you had high hopes and dreams, “Kaplan says. “It might give you the strong wish to catch those dreams today in your past life.” She adds that nostalgia can prevent you from “cutting yourself off from your aim”.
1.Feeling of nostalgia ______.
A．can cause you to think of your past which was full of hopes and dreams
B．might cause you to try to realize the golden dream in the present life
C．fill one with hopes for the future no matter what happens
D．bring about a love for the past and a hope for the future
2.The reason for grown persons to think back to their past is that ______.
A．time is hard, so they cannot keep up
B．they can hardly keep up with changes in today’s world with changes
C．many grown persons have little time keeping up with changes
D．they lived in the past, of which they are always proud
3.Which of the following is NOT talked about in the passage?
A．Too much nostalgia is harmful to our health.
B．Nostalgia shows that a person is not satisfied with his present life.
C．Only women have feelings of nostalgia.
D．A little nostalgia can make a person’s life more colorful.

Ⅳ. 阅读理解（共20题；每小题2分，满分40分）
第一节阅读理解（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给A, B, C和 D项中，选出最佳选项。
In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letters. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.
But a story about online communication changed my mind.
An old man, who suffered a lot from Parkinson's disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.
I, therefore, managed to get an e-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities that few other products can match.
E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn't want to have a face-to-face talk with your manager, you might talk with him through e-mail even if you are in the same office.
Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could clearly spend half a day clearing junk ads.
Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I'm sure there's and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting even in the world of modem communication.
As I listen to the sound of the modem, I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.
41. What caused the writer to become interested in e-mail and online communication?
A. The sound of the modem. B. His own illness.
C. The changing of his life. D. A sick old man's experience.
42. What is the most probable meaning of the underlined word "junk" in Paragraph 7?
A. Old and useless. B. New and useful.
C. Short but valuable. D. Long but clear.
43. What does the writer think of online communication?
A. It should replace old-fashioned letters completely.
B. It is perfectly and always does good to you.
C. It is extremely useful and convenient, but it may be inconvenient or even harmful.
D. It does more harm than good.
44. How did the sick old man keep in touch with his family members?
A. With the help of his computer.
B. By writing letters with his pen.
C. By making telephones calls.
D. By visiting them regularly.
45. According to the writer, traditional means of communication will never disappear because .
A. they are convenient and popular though they are slow
B. they help to keep the friendly relationship between people
C. most people cannot keep up with the development of technology
D. modem means of communication does too much harm
