Tired of living in the same location but don’t want to leave the house you love? That wouldn’t be a problem if architect Felipe Campolina had his way.
The Brazilian architect has designed a concept for a home tower consisting of portable, stackable (可叠起堆放的) apartment units, which he says opens up new possibilities for ways of living in the city.
His design would allow owners to take their home with them when they travel — whether for a weekend away or for longer periods, he said.
The mobile home tower project is at the concept stage, and it could be years before it is built, if ever at all.
But if it is realized, it would offer an eco-friendly solution to living in urban areas, Campolina said.
“We have enough technology to build with fewer materials and minimize (使减至最小) the impact on nature,” he said.
His vision would call for units with a green roof and walls and a system for recycling water.
The tower, whose first floor would be built nine meters above ground, would also make it possible to save space in thickly populated areas.
“It is designed to facilitate (使便利) its application in dense urban centers, where space is very limited,” he said.
Still just a concept, Campolina — who designed the building for architecture journal eVolo’s Skyscraper Competition — said with enough public interest, it just might become a reality one day.

Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.

There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).

Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.

Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.

1.Where can we find water?

A．We can find water when it turns into vapour.

B．Water is only in seas and rivers.

C．We can see water in deserts here and there.

D．Water can be found almost everywhere.

2.We can drink water when it is

A．a solid            B．aliquid            C．in the air          D．turned into ice

3.Clouds are made of

A．seas, rivers and lakes

B．blocks of ice

C．very small drops of water or snow crystals

D．solid, liquid and gas

4.Water has three states(状态). They are

A．solid, liquid and gas

B．solid, vapour, snow

C．drops of water, blocks of ice and crystals of water

D．ice, snow and air

 

Superconducting Materials

       The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff(超级材料). Material science -- once the least sexy technology – is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.

       The key to the new materials is researchers’ increasing ability to manipulate substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.

      A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion.

       Some advanced materials are old standard with a new twist. The newest fiberoptic(光学纤维的) cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.

       But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.

How many new materials are mentioned in this passage?

A Two      B Three    C Four    D Five

Why does the author mention genetic engineering and computer science?

A To compare them with the new materials.

B To show the significance of the new materials on the future world.

C To compare the new materials to them.

D To explain his view point.

Why is transition difficult?

A Because transition requires money and time.

B Because many manufacturers are unwilling to change their equipment.

C Because research on new materials is very difficult.

D Because it takes 10 years.

Where lies success of a country in the New Age of superstuff?

A It lies in research.      B It lies in investment.

C It lies in innovation.    D It lies in application.

Despite the fact that it has never been seen almost everyone is familiar with the legendary unicorn(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.
According to the legend, anyone attempting to catch a unicorn had to be extremely careful as it was very fierce and dangerous. A clever trick suggested by unicorn-trappers, in order to catch this amazing animal without being hurt by its horn, was for the hunter to stand in front of a tree and then to move quickly behind it as the unicorn dashed angrily. Hopefully, the creature could then be caught when its horn was stuck in the tree.
When hollowed out and used as a drinking-cup, the unicorn’s horn was said to have the power to offer protection against person. It was believed that nobody could be harmed-by drinking the contents of a unicorn’s horn. Right up until the French Revolution in 1789, the French court was said to have used cups made of “unicorn” horn in order to protect the king. In addition, the horn was said to have medicinal value, so much so that it could be sold for more than ten times the price of the same weight of gold. What, then, was “unicorn” horn? We know at times the rhino(犀牛) was confused with this legendary creature. A drinking-cup supposedly made of “unicorn” horn was discovered to be made of the horn of a rhino.
