听力原文：The key question for any only child is this: Why were you an only child？ It's a k
听力原文： The key question for any only child is this: Why were you an only child？ It's a key question for at least two reasons. If your parents had wanted several children, but could have you only, they are most likely to pour into you all the energy and attention that had been intended for several children. I call this the "Special Jewel" phenomenon. Only children, or special jewels often arrive when their parents are older-- usually in their thirties. These special jewels can become very spoiled and serf - centered. On the other hand, you may be an only child be cause your parents planned for only one and stuck to their plan. Your parents may give you a very strict and well-structured education to make you a little adult. Many only children grow up feeling unhappy because they always had to be such little adults.

Every artist knows in his heart that he is saying something to the public.Not only does he want to say it well, but he wants it to be something that has not been said before.He hopes the public will listen and understand what he wants to teach them, and what he wants them to learn from him.
What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experience into shapes and colors, not words.They seem to feel that a certain selection of shapes and colors, out of the countless billions possible, is exceptionally interesting for them and worth showing to us.Without their work we should never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist.
Most artists take their shapes and colors from the world of nature and from human bodies in motion and at rest; their choices indicate that these aspects of the world are worth looking at, that they contain beautiful sights.Contemporary artists might say that they merely choose subjects that provide an interesting pattern, that there is nothing more in it.Yet even they do not choose entirely without reference to the character of their subjects.
If one painter chooses to paint a decaying leg and another a lake in moonlight, each of them is directing our attention to a certain aspect of the world.Each painter is telling us something, showing us something, emphasizing something—all of which means that, consciously or unconsciously, he is trying to teach us.
1.An artist hopes that the public will ____.
A.understand him and learn from him
B.notice only shapes and colors in his work
C.teach him something
D.believe what he says in his work
2.It is hard to explain what a painter is saying, because he/ she ___.
A.uses shapes and colors instead of words
B.uses unusual words and phrases
C.does not express himself /herself well
D.does not say anything clearly
3.The writer points out that contemporary artists might say their choices of subject _____.
A.only provide interesting patterns
B.teach the public important truths
C.have no pattern or form
D.carry a message to the public
4.The writer also points out that contemporary art contains ____.
A.nothing but meaningless patterns
B.uninteresting aspects of the world
C.completely meaningless subjects
D.subjects chosen partly for their meanings
5.What is implied in this passage？()
A.A painting is more easily understood than a symphony.
B.Art is merely the arranging of shape and color.
C.Every artist tries to say something to the public.
D.One must look beyond shape and color to find what the artist is saying.

There are two great mysteries about the beach. One is why human beings flock there by thousands, only to prostrate(俯卧) themselves in dense packs of glistening flesh. The other is why the sand goes there. Strange as it seems, oceanographers have never really understood why sand piles up on the shore. Now Douglas Inman and Daniel Conley think they have solved the puzzle.
The puzzle had to do with waves. Though it might seem intuitive that waves carry water to shore, and sand along with it, it's not that simple. The crest(浪尖)of a passing wave lifts a given hit of water upward and landward, but the ensuing trough(波谷) pushes the water back down and Out to sea. Near the bottom, there the sand is, the water was always assumed to just slide back and forth—and the sand with it. "If you take a very aloof look at a beach," says Inman, "you'll realize that if the two motions move sand back and forth the same amount, then all the sand should end up in deep water.'
So for beaches to exist, the crest's onshore flow must somehow move enough sand up the beach to counter the seaward tug of both the trough and gravity . The pressure changes in the sand bed, Inman and Conley think, are the key to beach creation. They found that sand doesn't just slide back and forth with each passing wave. Under a trough, it does slide seaward, in a thin layer just above the bottom. But under a crest its movement is often more elaborate. The higher pressure under a crest—higher because the water is piled higher—forces water into the porous(多孔的) sand. This creates strong whirlpools just above the sand, which help loosen it. As the crest passes overhead, the sand first rushes across the bottom; then it abruptly turns violent lifting off the bottom in large, boiling bunches. Finally, just after the crest passes, the sand explodes up into the great water column. The boiling and rushing move more sand than the backsliding under a trough, so there's a net movement of sand toward the shore.
What is the primary purpose of this passage？
A．To explain why sand piles up on the beaches.
B．To explain why men only prostrate in the sea.
C．To propose a new explanation of a phenomenon.
D．To refute a misconception.

Unemployment in the state hit an all-time low of 2.1 percent this summer, the lowest in the nation. Though it has edged up a little since, it is still among the tightest labour markets in the US. And Connecticut is only the most extreme manifestation of the conditions that now prevail across America. Unemployment nationally is 4.1 percent, the lowest since 1970.
The performance of the US labour market in the late 1990s is as much a feature of the puzzlingly benign so-called New Economy.
For the past four years the US has enjoyed an average annual growth rate of 4 percent— up from an average of about 3 percent in the previous decade. Productivity improvements account for about two-thirds of that elevated output, as workers have increased their output per hour.
The rest has come from a rapid increase in the total number of workers, what economists call labour inputs. There has been a surge in new jobs—7m in the last three years—that has pushed the unemployment rate down into the uncharted territory of barely 4 percent.
Recent economic history suggests that, whenever unemployment has gone this low, the scramble for workers becomes so difficult that wages are rapidly bid up, and an inflationary spiral follows. But in the US in the past five years, wage growth has been muted. In the last year, total employee compensation in the private sector rose by just 3.3 percent, almost unchanged on the figure three years ago, when the unemployment rate was 5.4 percent.
"In some ways it's a bigger puzzle than the productivity puzzle," says Paul Krugman, professor of economics at the Massachusetts Institute of Technology. "How can we have such a low unemployment rate without an explosion of wages？"
A number of factors appear to have contributed.
In their search for workers to fill positions, companies have reached out to places they have not looked at in the past. As a result, more people are working than ever. The proportion of the population in employment reached a record high this year of more than 64 percent.
This expanded labour supply helps explain why companies have kept the lid on pay over the last few years. The availability of new sources of labour—women, retirees, college students among them—means companies may not have to give big pay rises to hire new workers. It also helps explain why the benefits of the New Economy are not always widely felt—more people seem to be working longer hours than ever.
But an expanded labour supply can only explain part of what has changed in the US in recent years. After all, unemployment—the proportion of the labour force out of work—has still declined, indicating that companies have drawn new workers not just from the pool of those not previously in the labour force, but also from the unemployed.
And yet still wage costs have remained muted.
One possible explanation is that companies have become more flexible in how they pay.
"At Newfield, we use a much broader variety of means to reward workers, including performance related pay, year-end bonuses, and extended contracts," says Mr. Ostop.
Why does Connecticut have the tightest labour market in the U. S. ？

It is astonishing how little is known about the working of the mind. But however little or much is known, it is fairly clear that the model of the logic-machine is not only wrong but mischievous. There are people who profess to believe that man can live by logic alone. If only they say, men developed their reason, looked at all situations and dilemmas logically, and proceeded to devise rational solutions, all human problems would be solved. Be reasonable. Think logically. Act rationally. This line of thought is very persuasive, not to say seductive, 1. It is astonishing, however, how frequently the people most fanatically devoted to logic and reason, to a cold review of the "facts" and a calculated construction of the truth, turn out not only to be terribly emotional in argumentation, but obstinate any "truth" is "proved"——deeply committed to emotional positions that prove reek-resistible to the most massive accumulation of unsympathetic facts and proofs.
2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation.
Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time.
4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.
