Here&39;s a familiar story. You&39;re sitting at the dinner table with a furry, four-legge

d friend scratching at your feet. When you look down, those cute eyes are almost impossible to resist.

What is it about a dog&39;s gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.

The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.

The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.

Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.

Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.

This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.

11. What do we know about oxytocin？

A.It regulates blood flow

B.It promotes bonding

C.It is in the human gene

D.It is good for health

When we look deeply into a dog's eyes, the levels of our oxytocin ____.A.reduce over time

B.go either up or down

C.are on the rise

D.remain unchanged

At the beginning wolves followed humans to ____.A.eat the food left by humans

B.guard against large animals

C.take humans for food

D.hunt large animals together

Over time some wolves turned into dogs ____.A.due to their loyalty

B.due to the changing environment

C.for better survival

D.for better cooperation

What does Nagasawa9s study aim to do？A.Explore the role of human-wolf partnership

B.Show the characteristics of the cuddle chemical

C.Explain the bond between humans and dogs

D.Understand the evolution of species

第5题
Modem technology and science have produced a wealth of new materials and new ways of u
sing old materials. For the artist this means wider opportunities. There is no doubt that the limitations of materials and nature of tools both restrict and shape a man's work. Observe how the development of plastics and light metals as well as new methods of welding (焊接法)has changed the direction of sculpture. Transparent plastic materials allow one to look through an object, to see its various sides overlapped with each other (as in Cubism or in an X ray). Today, welding is as prevalent as casting was in the past. This new method encourages open designs, where surrounding and intervening space becomes as important as form. itself.

More ambiguous than other scientific inventions familiar to modem artists, but no less influential, are the psychoanalytic studies of Freud and his followers, discoveries that have penetrated recent art, especially Surrealism. (超现实主义)

The surrealists, in their struggle to escape the monotony and frustrations of everyday life, claimed that dreams were the only hope. Turning to the irrational world of their unconscious, they banished all time barriers and moral judgments to combine disconnected dream experiences from the past, present and intervening psychological states. The surrealists were concerned with overlapping emotions more than with overlapping forms. Their paintings often become segmented capsules of associative experiences. As to them, obsessive and often unrelated images replaced the direct emotional messages of Expressionism. They did not need to smash paint and canvas ; they went beyond this to smash the whole continuity of logical thought.

There is little doubt that contemporary art has taken much from contemporary life. In a period when science has made revolutionary strides, artists in their studios have not been unaware of scientists in their laboratories. At the same time, this has rarely been a one-way street. Painters and sculptors, though admittedly influenced by modem science, have also molded and changed our world. If break-up has been a vital part of their expression, it has not always been a symbol of destruction. Quite the contrary: it has been used to examine more fully, to penetrate more deeply, to analyze more thoroughly, to enlarge, isolate and make more familiar certain aspects of life that earlier were apt to neglect. In addition, at times it provides rich multiple experiences so organized as not merely to reflect our world, but in fact to interpret it.

41.The author argues that Freud's studies .

A.are more comprehensible than other scientific inventions

B.are more controversial than any other scientific findings

C.have been largely influenced by contemporary arts

D.have found their expression in the Surrealism's claims

42.The Surrealism made every endeavor .

A.to transform. real existence into incoherent dreams

B.to diminish all time barriers and moral judgments

C.to express their disconnected unconscious thoughts

D.to substitute direct expressions for fragmented images

Do you find getting up in the morning so difficult that it is painful? This might be c
Do you find getting up in the morning so difficult that it is painful？ This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labour through your work you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: “Get up, John! You’ll be late for work again!”The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can’t change your energy cycle, but you can learn to make your life it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll get up steam (鼓起干劲) and work better at your low point. Get off to a slow start which saves your energy. Get with a leisurely yawl and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble some search for clean clothes by laying them out the night before. When ever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

1.If a person finds getting up early a problem, most probably _______.

A、he is a lazy person

B、he refuses to follow his own energy cycle

C、he is at his peak in the afternoon or evening

2.Which of the following may lead to family quarrels according to the passage_______.

A、Unawareness of energy cycles.

B、Familiar monologues.

C、A change in a family member’s energy cycle.

D、A change in a family member’s energy cycle.

3.If one wants to work more efficiently at his low point in the morning, he should _____.

A、change his energy cycle

B、overcome his laziness

C、go to bed earlier

4.You are advised to rise with a yawn and stretch because it will ______.

A、help to keep your energy for the day’s work

B、help you to control your temper early in the day

C、enable you to concentrate on your routine work

D、keep your energy cycle under control all day

5.Which of the following statements is NOT TRUE_______.

A、Getting off to work with a minimum effort helps save one’s energy.

B、Dr. Kleitman explains why people reach their peak at different hours of day.

C、Habit helps a person adapt to his own energy cycle.

D、Children have energy cycles, too.

Some psychologists maintain that mental acts such as thinking are not performed in the bra
in alone, but that one's muscles also participate. It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies.

You surely are not surprised to be told that you usually listen to music not only with your ears but with your whole body. Few people can listen to music that is more or less familiar without moving their body or more specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted to direct the orchestra even though he knows them is a competent conductor on the job.

Strange as this behavior. may be, there is a very good mason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener "feels" himself into the music with more or less noticeable motions of his body.

The muscles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less noticeable.

Some psychologists maintain that thinking is ______.

A．not a mental process

B．more of a physical process than a mental action

C．a process that involves our entire bodies

D．a process that involves the muscles as well as the brain

听力原文：Outrageous shopping bills are a familiar nightmare for many compulsive shoppers.
And contrary to popular opinion, men suffer that nightmare nearly as often as women. A new survey finds that both genders are almost equally likely to suffer compulsive buying disorder, a condition marked by uncontrollable, unnecessary and unaffordable shopping sprees. Researchers used to estimate that between 2 and 16 percent of the US population suffered compulsive buying disorder, and that 90 percent of sufferers were female. But a 2004 telephone survey of more than 2,500 American adults found that 6 percent of women and about 5.5 percent of men are compulsive shoppers; that's more than 1 in 20 adults. The sexes do not shop at the same aisles though. Experts say that women are more likely to binge-buy things like clothes or gifts for other people while men tend to buy expensive electronics. This survey is the first to find such a high number of compulsive shoppers in the general population. Study authors hope that this finding can convince doctors of how many people are hurt by the disorder, so they can make finding a cure a priority.

How many people of US population suffered compulsive buying disorder？

A．2 to 60 percent.

B．2 to 16 percent.

C．20 to 60 percent.

D．16 to 20 percent.
