A Train Floating On Air
A train that floats on air? It's not magic—it's magnets (磁).And it's close to reality.
In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus.In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power.And in China, a magnet train line linked Shanghai with nearby Pudong Airport.
These trains use magnetic levitation (悬浮) technology, “maglev” for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles repel each other.
How does it work?
Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past.
When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down.
Maglev doesn't rely on the friction (摩擦力) of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop.

Sitting on the peaceful coast of Galapagos Islands. Ecuador, watching the sun move quietly into the sea, you shouldn’t forget that Charles Darwin (1809-1882) arrived here in 1835. He stayed on the islands for five weeks, observing various animals. This finally inspired (启发) his famous work, On the Origin of Species. You can certainly follow Darwin’s footsteps and enjoy a trip from four to seven days to the islands.
The most well-known animals of the Galapagos is the giant tortoise（巨型海龟），which can be seen moving slowly around the highlands of Santa Cruz, the second largest island in the archipelago （群岛）. Some of these creatures are so old that they might have been in their youth by Darwin himself.
Despite strict control over activities and timing, your stay on the Galapagos will be remembered as a chain of incomparable pictures; diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and most magically, seeing a whale and her baby surface with a great breath of air.
Travelling between the islands and observing the wildlife that so inspired Darwin, so you will feel as though you are getting a special view of an untouched world. At night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.What do we know about Danwin’s visit to the islands?

It is hardly surprising that clothing manufacturers （生产商）follow certain uniform standards for various features（特征）of clothes. What seems strange , however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men’s clothes tend to button from the right, and women’s form the left. Considering most of the word’s population-men and women-are right-handed, the men’s standard would appear to make more sense for women. So why do women’s clothes button from the left?
History really seems to matter here. Button first appeared only on the clothes of the rich in the
17th century, when rich women were dressed by servants. For the mostly right-handed servants, having women’s shirts button from the left would be easier. On the other hang, having men’s shirts button form the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hang would be less likely to get caught in the shirt.
Today women are seldom dressed by servants, but buttoning form the left is still the standard for them. Is it interesting? Actually, a standard , once set, resists change. At a time when all women’s shirts buttoned form the left, it would have been risky for any single manufacture to offer women’s shirts that buttoned the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides from the right, since anyone who noticed that would believe they were wearing men’s shirts.What is surprising about the standard of the clothing industry?
| A．It has been followed by the industry for over 400 years. |
| B．It is different for men’s clothing and women’s. |
| C．It woks better with men than with women. |
| D．It fails to consider right-handed people. |
What do we know about the rich men in the 17th century?
| A．They tended to wear clothes without buttons. |
| B．They were interested in the historical matters. |
| C．They were mostly dressed by servants. |
| D．They drew their swords from the left. |
Women’s clothes still button from the left today because.
| A．adopting men’s style is improper for women |
| B．manufacturers should follow standards |
| C．modern women dress themselves |
| D．customs are hard to change |
The passage is mainly developed by .
| A．analyzing cause |
| B．making comparisons |
| C．examining differences |
| D．following the time order |

Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat, when a manager gets a new sports car, a big house and pleasure boats dance into view.
The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears.
The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War Ⅱ, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared; the “life-enriching” level. While the other levels involve physical satisfaction, that is, the need in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing.
On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their inc
ome increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the hea
lth, safety, and leisure to enjoy more fully the good things on the first four levels.According to the passage, man will begin to think about such needs as housing and clothing only when.
| A．he has saved up enough money |
| B．he has grown dissatified with his simple shelter |
| C．he has satisfied his hunger |
| D．he has learned to build houses |
It can be inferred from the passage that by the end of World War Ⅱ, most Americans.
| A．were very rich | B．lived in poverty |
| C．had the good things on the first three levels | |
| D．did not own automobiles |
Which of the following is NOT related to “physical satisfaction” ?
| A．A successful career. | B．A comfortable home. |
| C．A good meal. | D．A family car. |
What is the main concern of man on the fourth level?
| A．The more goods the better. |
| B．The more mental satisfaction the better. |
| C．The more “luxury” items the better. |
| D．The more earnings the better. |
