London has a new magazine. But it’s not printed on paper. Everyone who has a television can receive it because it is on TV.
In order to read this magazine you have to have a decoder. Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There’s a wide choice--- everything is included from cooking to the latest sports news.
If you want to read the news, the first thing you have to do is to turn to the index page which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on pages 101 to 109, so you push out the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible so you decide to go shopping and dial 162 for a list of the week’s best bargains. But should you drive or take the train ? To answer the question you only have to press 189 for the traffic report. It’s very simple to use. But probably the best thing about the service is that it’s being updated all the time. Journalists type new material directly onto the screen and whole pages of the magazine can be replaced in minutes.
London has already had three services. One, transmitted(传输)by ITV, is called ORACLE, while the other two, on BBC, are called CEEFAX, because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized. BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people agree that this is a breakthrough as great as the invention of printing, which could change not just our reading habits but our whole way of life.

根据短文内容,从下边的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。

A . The different structure of blue holes.????????

B. Why scientists are interested in blue holes.????????

C. How a blue hole comes into being.

D. Blue holes exploring is becoming popular.

E. Rules to obey when diving into blue holes.

F. The general definition of a blue hole.

1.______________

??? A blue hole is a flooded sea cave with a hole that opens up at the land's surface. These cave systems form in carbonate rock, often on islands. Some blue holes have very special rock formations and water chemistry. Far below sea level, they contain some of the harshest environments on Earth, with no oxygen and no light. Yet these areas are filled with life forms that have adapted to the extreme conditions.

2.___________

??? Blue holes get their name from the color some have when seen from the air. The color is usually a reflection of the sky on the water. Blue holes are the result of erosion in which water breaks down rock. Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass. These holes later filled with sea water as the sea level changed. The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations.

3. ____________

??? These flooded cave systems can be found in the ocean, or they can be found inland. Ocean caves are affected by tides, so they always have water movement. But blue holes on land are very still. They have several layers of water, chemicals, and bacteria. The top layer of fresh water comes from rainfall. This layer acts like a cap on top of the layered mixture, and keeps out oxygen from the atmosphere. The fresh water floats on a denser layer of saltwater. Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water. Underneath this layer is anoxic seawater -- water that does not contain any oxygen.

4.___________

??? Information gathered from these blue holes is helping scientists to increase their understanding of biology, archaeology and geology. But exploring these blue hole environments brings danger as well as discovery. Scientists are interested in these caves because oxygen-free conditions there are similar to those on Earth long ago, before oxygen existed on our planet. But there are many difficulties involved in diving into blue holes.

5.___________

One reason blue holes have not been fully explored is that they can be extremely dangerous. There are many safety rules that divers must follow to help ensure their survival. First, divers must have training and experience to swim in these caves. Divers who explore a cave for the first time must establish a thin rope called a guideline. This line helps them to safely enter and exit the cave without getting lost.

Whoever has made a voyage up the Hudson River must remember the Catskill Mountains. They are a branch of the great Appalachian family, and can be seen to the west rising up to a noble height and towering over the surrounding country. When the weather is fair and settled, they are clothed in blue and purple, and print their beautiful shapes on the clear evening sky, but sometimes when it is cloudless, gray steam gathers around the top of the mountains which, in the last rays of the setting sun, will shine and light up like a crown of glory (华丽的皇冠).

     At the foot of these mountains, a traveler may see light smoke going up from a village.

     In that village, and in one of the houses (which, to tell the exact truth, was sadly time-worn and weather-beaten), there lived many years ago, a simple, good-natured fellow by the name of Rip Van Winkle.

     Rip's great weakness was a natural dislike of all kinds of money-making labor. It could not be from lack of diligence (勤劳), for he could sit all day on a wet rock and fish without saying a word, even though he was not encouraged by a single bite. He would carry a gun on his shoulder for hours, walking through woods and fields to shoot a few birds or squirrels. He would never refuse to help a neighbor, even in the roughest work. The women of the village, too, used to employ him to do such little jobs as their less helpful husbands would not do for them. In a word, Rip was ready to attend to everybody's business but his own.

      If left to himself, he would have whistled ( 吹口哨) life away in perfect satisfaction; but his wife was always mad at him for his idleness (懒散). Morning, noon, and night, her tongue was endlessly going, so that he was forced to escape to the outside of the house -- the only side which, in truth, belongs to a henpecked husband.

Which of the following best describes the Catskill Mountains?

     A. They are on the west of the Hudson River.

     B. They are very high and beautiful in this area.

     C. They can be seen from the Appalachian family.

     D. They gather beautiful clouds in blue and purple.

The hero of the story is probably_____________.

A. hard-working and likes all kinds of work

B. idle and hates all kinds of jobs

C. simple, idle but very dutiful

D. gentle, helpful but a little idle

The underlined words "henpecked husband" in the last paragraph probably means a man who

    A. likes hunting        B. is afraid of hens

    C. loves his wife        D. is afraid of his wife

What would be the best title for the text?

     A. Catskill Mountains.        B. A Mountain Village.

     C. Rip Van Winkle.          D. A Dutiful Husband.

As China becomes increasingly urbanized (城市化), it has to find space for its urban and rural citizens as both groups become increasingly integrated. Experts suggest a possible model way may be “re-inventing” a “garden city”.

China’s mega-cities are bursting at the borders and the country is now undergoing the quickest and biggest urbanization in the history of mankind. It is estimated that by 2025, China will have 400 million more people living in its cities, raising its urban population to 900 million. Besides, new satellite towns are mushrooming on the urban fringes while city ring roads are rippling outwards into the countryside at amazing speed. Satellite maps collected by Professor Joshua Bolchover at the University of Hong Kong bring the problem sharply into focus. They track the changing rural-urban framework in the past 30 years, and suggest that cities are cruelly destroying surrounding rural land and rapidly reducing the amount of arable (可耕种的) land, which gives way to new residential blocks, new industrial zones, new financial centers and the other inevitable signs and signatures of economic growth.

This, however, is not sustainable growth pattern, especially when China has the world’s largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora (大移居) when replaced rural communities are forced into the cities.

On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.

The concept is already practiced at the grassroot level. Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It’s common to see organic “hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translate to tangible (=" practical)" benefits, such as safe, nutritious vegetables, a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there’re fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit --- all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are doing.

Although people like Zhang are still rare and the greening of roof space with vegetables and fruit takes skill and energy, with more positive media exposure and advanced technology there is the prospect that garden city will become common practice in the near future. By then, cities will no longer look so gray when seen from the satellites.

1.Some experts suggest re-inventing a “garden city” because ______.

A.it is the only model way to save the cities

B.it helps stop destroying the rural areas

C.increasing urbanization takes place in China

D.China has the largest population to feed

2.What is the purpose of paragraph 2?

A.To show the experts’ concern about the increase of population.

B.To persuade people into supporting economic growth in cities.

C.To explain the reasons for the change of rural-urban framework.

D.To inform the readers of the consequences of quick urbanization.

3.In Hua Li’s opinion, a combination of country and city will ______.

A.benefit the environment and lower living costs

B.become a project that needs a long-term study

C.lead to more rural communities being replaced

D.attract more farmers to take tours in cities

4.Zhang is mentioned (Paragraph 5) to show that ______.

A.he achieves his dream to own a hanging garden

B.hanging gardens are becoming more popular

C.the garden contributes to a better neighborhood

D.he is a pioneer to practise the gardening concept

5.As for the concept of the “garden city”, the writer feels ______.

A.desperate         B.hopeful           C.disappointed       D.concerned
