Directions: Read through the following passages. Choose the best answer and put the letter in the bracket. (20%)

1.

(A)   When Steve Cole was a postdoc, he had an unusual hobby: matching art buyers with artists that they might like. The task made looking at art, something he had always loved, even more enjoyable. “There was an extra layer of purpose. I loved the ability to help artists I thought were great to find an appreciative audience,” he says.    At the time, it was nothing more than a quirky sideline. But his latest findings have caused Cole — now a professor at the Cousins Center for Psychoneuroimmunology at the University of California, Los Angeles — to wonder whether the exhilaration and sense of purpose that he felt during that period might have done more than help him to find homes for unloved pieces of art. It might have benefited his immune system too.     At one time, most self-respecting molecular biologists would have scoffed at the idea. Today, evidence from many studies suggests that mental stales such as stress can influence health. Still, it has proved difficult to explain how this happens at the molecular level — how subjective moods connect with the vastly complex physiology of the nervous and immune systems. The field that searches for these explanations, known as psychoneuroimmunology (PNI), is often criticized as lacking rigour. Cole’s stated aim is to fix that, and his tool of choice is genome-wide transcriptional analysis: looking at broad patterns of gene expression in cells. “My job is to be a hard-core tracker,” he says. “How do these mental states get out into the rest of the body?”      With his colleagues, Cole has published a string of studies suggesting that negative mental states such as stress and loneliness guide immune responses by driving broad programs of gene expression, shaping our ability to fight disease. If he is right, the way people see the world could affect everything from their risk of chronic illnesses such as diabetes and heart disease to the progression of conditions such as HIV and cancer. Now Cole has switched tack, moving from negative moods into the even more murky territory of happiness. It is a risky strategy; his work has already been criticized as wishful thinking and moralizing. But the pay-off is nothing less than finding a healthier way to live.      “If you talk to any high-quality neurobiologist or immunologist about PNI, it will invariably generate a little snicker,” says Stephen Smale, an immunologist at the University of California, Los Angeles, who is not affiliated with the Cousins Center. “But this doesn’t mean the topic should be ignored forever. Someday we need to confront it and try to understand how the immune system and nervous system interact.” With which of the following subjects is the passage mainly concerned?

(B)    “The only thing we have to fear is fear itself,”said Franklin D. Roosevelt. He might have been onto something: research suggests that people are happy to endure a bit more pain, if it means they spend less time waiting for it.    Classical thanes of decision-making suppose that people bring rewards forward and postpone punishments, because we give far-off events less weight. This is called “temporal discounting”. But this theory seems to go out the window when it comes to pain.   One explanation for this is that the anticipation of pain is itself unpleasant, a phenomenon that researchers have appropriately termed “dread”.   To investigate how dread varies with time, Giles Story at University College London, and his colleagues, hooked up 33 volunteers to a device that gave them mild electric shocks. The researchers also presented people with a series of choices between more or less mildly painful shocks, sooner or later.    During every “episode” there was a minimum of two shocks, which could rise to a maximum of 14, but before they were given them, people had to make a choice such as nine extra shocks now or six extra shocks five episodes from now. The number of shocks they received each time was determined by these past choices.    No pain, no gain.    Although a few people always chose to experience the minimum pain, 70 per cent of the time, on average, participants chose to receive the extra shocks sooner rather than a smaller number later. By varying the number of shocks and when they occurred, the team was able to figure out that the dread of pain increased exponentially as pain approached in time. Similar results occurred in a test using hypothetical dental appointments.   “This study demonstrates that the fear of anticipation is so strong it can reverse the usual pattern of time discounting,” says George Loewenstein, a professor of economics and psychology at Carnegie-Mellon University in Pittsburgh, Pennsylvania, “It’s probably not an exaggeration to say that as much, or more, of the pains of life come from anticipation and memory than from actual experience.”     The study could well have implications for medicine and health policy, because an understanding of how people judge pain is important for presenting them with options about potentially painful treatments.     “You should avoid emphasizing waiting times,”says Story. “And if you can make something seem unavoidable, people may be more likely to confront it to minimise dread.”      Story hopes that this kind of psychological study will aid the development of diagnostic tools. “Looking at these kinds of preferences might help predict whether people will make healthy or unhealthy choices,” he says. Which of the following statements best expresses the main idea of the passage?

A.No pain, no gain
B.The only thing we have to fear is fear itself
C.Wailing for pain can cause more dread than pain itself
D.Dread varies with time

7.What can be said about temporal discounting?

A.It is often used in lottery.
B.It is a marketing strategy.

A.very soon
B.early enough
C.in the end
D.fairly long period of time

9.Which of the following is NOT true about the study made by Story and his colleagues?

A.It helped to develop diagnostic tools.
B.It showed that the dread of pain increased rapidly as pain approached in time.
C.It changed round the usual pattern of temporal discounting.
D.It involved giving mild electric shocks to a number of subjects.

10.What can be inferred from the passage when people have to receive painful treatments?

A.They are more likely to take them.
B.They will try to postpone them.
C.They will consider whether the treatments are worth confronting.
D.They will abandon such treatments.

二、信息題

Directions: Read the following passage, and then fill in the table with the information based on the passage. (10%×2%)

11.It wasn’t until the mid 20th century that doctors realised asthma attacks were caused by the swelling and contraction of the airways, Consequently, in the last 40 years there have been many developments in the treatment of asthma. There are presently two main types of medicine: preventers and relievers. A preventer is used every day and reduces the swelling of the airways, cutting the risk of on attack. A reliever, such as Ventolin, is taken when breathing has become difficult: this actually relaxes the muscles of the airways, reducing constriction and improving the airflow. The medicine is usually taken using a device for medical purpose. Prevention is also good treatment so if you have asthma, remember to keep generally healthy, take regular exercise and lots of vitamin C to avoid colds and flu—which can be dangerous for asthma sufferers. A healthy diet is also important, and do watch what you eat, as certain foods or food with certain substances to change the flavor can start asthma. By taking the right medication and making the right lifestyle choices, there is no reason why most asthma sufferers shouldn’t be able to lead perfectly healthy and active lives.

Directions: Fill in each blank with a suitable word given below. (10%)

41.   At the yearly Rottnest Channel Swim in Western Australia, participants often smear their bodies with animal fat for insulation(36) the 70-degree water. But their own body fat also helps to keep them warm, like an extra layer of clothing (37) the skin. When scientists studied aspects of the event in 2006, they found that swimmers (38) a greater body mass index (BMI) appear to be at much (39)risk of getting hypothermia. Under certain conditions, though, overweight people might feel (40) than people of average weight. That’s because the brain combines two signals—the temperature (41) the body and the temperature on the surface of the skin—to determine when it’s time to constrict blood vessels (which (42) heat loss through the skin) and trigger shivering (which (43) heat). And since subcutaneous fat traps heat, an obese person’s core will tend to remain warm (44) his or her skin cools down. According to Catherine O’Brien, a research physiologist with the U.S. Army Research Institute of Environmental Medicine, it’s possible that the lower skin temperature would give (45) people the sense of being colder overall.
