Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night-flying birds are able to follow the stars in their long-distance flights.
A dove had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
But the stars are apparently their principal means of navigation. When the stars are hidden by clouds, they apparently find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.
The reason why birds don't get lost on long flights ______.
A．have been known to scientists for years
B．have only recently been discovered
C．are known by everyone
D．will probably remain a mystery

Getting a Chinese visa was easy enough. The Mongolian embassy (大使馆) seemed a bit unprepared for me, or in fact any other tourist, wanting to visit the country in winter and it took half an hour of knocking at the door before I got an answer. The Mongolian visa, however, has a map of the country in the background that should come in handy if I get lost out on the grassland.
It was getting a Russian visa that had me wondering if I'd ever be able to leave. The requirements for the visa, especially for the trip that ! plan to take, were a mountain of paperwork. I was required to prove, for example, where and when I plan on staying in each city and what train I plan to catch between cities.
I've spent a lot of time preparing for this trip, but ! still have no idea what to expect on this journey. The planning and packing has taken my mind off any worries I have so now everything is ready and I just want to get going. I'm sure I will see some interesting people and see some wonderful sights, and the sense of the unknown makes it all the more exciting.
How do the writer's friends feel about the delay of his trip？
A．Grateful.
B．Impatient.
C．Delighted.
D．Worried.

But my own worry today is less that of the overwhelming problem of elemental literacy than it is of the slightly more luxurious problem of the decline in the skill even of the middle-class reader, of his unwillingness to afford those spaces of silence, those luxuries of domesticity and time and concentration, that surround the image of the classic act of reading, it has been suggested that almost 80 percent of America's literate, educated teenagers can no longer read without an accompanying noise (music) in the background or a television screen flickering at the corner of their field of perception. We know very little about the brain and how it deals with simultaneous conflicting input, but every common-sense intuition suggests we should be profoundly alarmed. This violation of concentration, silence, solitude goes to the very heart of our notion of literacy; this new form. of part-reading, of part-perception against background distraction, renders impossible certain essential acts of apprehension and concentration, let alone that most important tribute any human being can pay to a poem or a piece of prose he or she really loves, which is to learn it by heart. Not by brain, by heart; the expression is vital.
Under these circumstances, the question of what future there is for the arts of reading is a real one. Ahead of us lie technical, psychic, and social transformations probably much more dramatic than those brought about by Gutenberg, the German inventor in printing. The Gutenberg revolution, as we now know it, took a long time; its effects are still being debated. The information revolution will touch every fact of composition, publication, distribution, and reading. No one in the book industry can say with any confidence what will happen to the book as we've known it.
The picture of the reading ability of the American people, drawn by the author, is ______.
A．rather bleak
B．fairly bright
C．very impressive
D．quite encouraging
第5题
Why should this be？ From the complexity of causes responsible for the present commonplace interview form, a few are worth singling out, such as the revolt against rationality and the worship of feeling in its place. To the young of the 60s, the painstaking search for understanding of a given political problem may have appeared less fruitful and satisfying than the free expression of emotion which the same problem generated. Sooner or later, broadcasting was bound to reflect this.
This bias against understanding has continued. To this we must add the professional causes that have played their part. The convention of the broadcast interview had undergone little change or radical development since its rise in the 50s. When a broadcasting form. ceases to develop, its practitioners tend to take it for granted and are likely to say "how" rather than ask "why".
Furthermore, these partly psychological, partly professional tendencies were greatly accelerated by the huge expansion of news and current affairs output over the last 15 years. When you had many, additional hours of current affairs broadcasting, interviewing turned out to be a far cheaper convention than straight reporting, which is costly in terms of permanent reporters and time preparation. The temptation to combine an expanded news and current affairs service with a relatively small additional financial expense by making the interview happen everywhere proved overwhelming.
To be fair, there are compensating virtues in interviewing, such as immediacy and authority, yet in all honesty I must say that the spread of the interviewing arrangement has led to a corresponding diminution of quality broadcasting.
According to the author, in the past politicians thought that television interviewers ______.
A．knew more about politics than they did
B．should be honoured to meet them
C．really were eager to be politicians too
D．gave them a difficult time in interviews
第6题
Foods which do not contain chemical additives (添加剂) and which have not been affected by chemical fertilizers, widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic (有机的) matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures(牧场). Compare this with what happens in the mass production of poultry: there are farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food, they . also lay eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually a non-essential food! Al though a natural alternative, such as honey, can be used to sweeten food if it is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the form. of calories. There are no vitamins in it, no minerals and no fiber.
It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example, the fiber has been removed．But it is present in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of whole meal bread and more vegetables by modem experts on "healthy eating".
People have become more interested in natural foods because ________.
A．they are more health conscious
B．they want to taste all kinds of foods
C．natural foods are more delicious than processed foods
D．they want to return to nature

Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the plummeting prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.
In many parts of the world renewable energy is already a principal energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.
President Trump has underlined fossil fuels – especially coal – as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation – and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.
The question "what happens when the wind doesn’t blow or the sun doesn’t shine？" has provided a quick put-down for skeptics. But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.
The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now, this massive investment could change the picture rapidly in coming years.
While there’s a long way to go, the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up – perhaps just in time to have a meaningful effect in slowing climate change. What Washington does – or doesn’t do – to promote alternative energy may mean less and less at a time of a global shift in thought.
26、The word "plummeting" (Line 3, Para 2) is closest in meaning to_____.
A.stabilizing
B.changing
C.falling
D.rising
According to Paragraph 3,the use of renewable energy in America______.A.is progressing notably
B.is as extensive as in Europe
C.faces many challenges

Which of the following is true about clean energy according to Paragraphs 5&6？A.Its application has boosted battery storage
B.It is commonly used in car manufacturing
C.Its continuous supply is becoming a reality
D.Its sustainable exploitation will remain difficult
It can be inferred from the last paragraph that renewable energy_____.A.will bring the US closer to other countries
B.will accelerate global environmental change
C.is not really encouraged by the US government
D.is not competitive with regard to its cost

Tea is available in more places than ever. "Tea was one of the most prolific beverage categories in 1999," with 24 percent more products offered over the previous year, reports Tom Vierhile of Marketing Intelligence Service, which tracks food and beverage trends. And the Tea Association of the United States reports that from 1990 to 1999, annual sales of the drink grew to $ 4.6 billion from $1.8 billion. "Green tea is seen by consumers as a 'functional food' delivering health benefits beyond sustenance," says Vierhile.
Recently published studies point out that not all brews are created equal. Only teas that come from the leaves of the plant Camellia sinensis — which, in their raw state are brewed to make green tea, and, with curing, can be turned into oolong and black tea leaves — have been shown to contain health benefits. Other herbal teas and infusions may taste good, yet they do little more than warm up the drinker. But for Camellia sinensis, the evidence is powerful. In a 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent compared with non-tea drinkers, and other studies have suggested that the antioxidants in these so-called real teas can also prevent cancer.
One such antioxidant in green tea is ECGC, a compound 20 times as powerful as vitamin E and 200 times as powerful as vitamin C. "When people ask me for something good and cheep they can do to reduce their cancer risk, I tell them drink real tea." Says Mitchell Gaynor, director of medical oncology at New York City's Strang-Cornell Cancer Prevention Centre.
Among those inspired to become a green-tea drinker is Tess Ghilaga. A new York Writer who took it up after consulting a nutritionist six years ago. "I've never been a coffee drinker." says Ghilaga, 33, "she told me to start drinking green tea for the antioxidant properties." Now Ghilaga and her husband routinely brew tea they order theirs from Inpursuitoftea.com, an internet tea company, which sells a variety of ready-made and raw teas. http://www. alitea.com/ — along with green, black, and oolong tea, this company sells a wide variety of herbal teas and offers a "Tea of the Month" club. http://www. Teasofgreen.com/ — this site sells higher-end green, black and oolong teas and has good tips on proper storage and preparation of tea. http://www. tea.com/ — tea drinkers can find links to sites offering tea lore, such as articles about tea ceremonies in foreign lands. An exhaustive "frequently asked question" file found out the site.
What do recent studies reveal about tea drinking？
A．Many tea houses have sprung up to meet the market demands.
B．Drinking tea can cut the risk of lung cancer in particular.
C．Tea is rather a magical drinking material to slow down the aging process.
D．Many die-hard coffee brewers have developed strong sentiments towards tea.
