　　Passage 1

　　It began as just another research project, in this case to examine the effects of various drugs on patients with a severe mood disorder. Using an advanced brain scanning technology—the clumsily named echo-planar magnetic resonance spectroscopic imaging (磁共振光譜成像) procedure, or EP-MRSI -researchers at Boston’s McLean Hospital scanned the medicated and unmedicated brains of 30 people with bipolar disorder in order to detect possible new treatments for the more than 2 million American adults who suffer from the disease.

　　But something unexpected happened. A patient who had been so depressed and could barely speak became ebullient after the 45-minute brain scan. Then a second patient, who seemed incapable of even a smile, emerged actually telling jokes. Then another and another. Was this some coincidence? Aimee Parow, the technician who made these observations (she is now a medical student in New York) didn’t think so. She mentioned the patients’ striking mood shifts to her boss, and together they completely refocused the study: to see if the electromagnetic fields might actually have a positive effect on depressive mood.

　　As it turns out, they did. As reported last month in the American Journal of Psychiatry, 23 of the 30 people who were part of the study reported feeling significantly less depressed after the scan. The most dramatic improvements were among those who were taking no medication. The researchers are cautious: Says Bruce Cohen, McLean’s president and psychiatrist in chief: “I want to emphasize that we are not saying this is the answer...but this is a completely different approach in trying to help the brain than anything that was done before.”

　　It’s a completely different approach because of the way the magnetism is applied to the brain. But it’s an example of new research on an old idea that the brain is an electromagnetic organ and that brain disorders might result from disarray in magnetic function. The idea has huge appeal to psychiatrists and patients alike, since for many people the side effects of psychiatric drugs are almost as difficult to manage as the disease itself. And 30 percent of the nearly 18.8 million people who suffer from depression do not respond to any of the antidepressants available now. People with other severe mental disorders might benefit as well. And while no one fully understands exactly why or how the brain responds as it does to electrical currents and magnetic waves, new research is offering some possible explanations.

　　This area of psychiatric research and treatment has an unpleasant history to overcome. “Shock treatment,” technically known as electroconvulsive therapy (電休克療法) or ECT, has been around since the 1930s, but it carries with it an unpopular public image which comes mostly from horrible movies. And in fact, it was in the early days a brutal procedure. But research on the magnetic brain has led to improvements in such treatments, and their use is on the rise. In 1980, 30,000 people received ECT; in 2001, nearly 100,000. Although there are still side effects - headaches and memory problems primarily - the days of bitten tongues, and broken bones are largely a thing of the past. And the response rate, especially for treatment of drug-resistant depression, is as high as 70 percent.

　　41. The project described in the first paragraph aimed at finding______.
　　A. who had bipolar disorder
　　B. what improved people’s moods
　　C. whether magnetic scanning was a treatment for depression
　　D. how patients with a mood disorder responded to certain drugs

　　42. The word “ebullient” in paragraph 2 can be best replaced by ______.
　　A. interested
　　B. quiet
　　C. excited
　　D. sorrowful

　　43. The findings show that electromagnetic fields may______.
　　A. treat mental disorders
　　B. cause mental disorders
　　C. reduce the effectiveness of some drugs
　　D. increase the effectiveness of some drugs

　　44. Which statement is true about “Shock treatment”?
　　A. It’s now the most popular mental treatment.
　　B. It’s becoming less cruel and more effective.
　　C. It has close relation with the movie industry.
　　D. It works only with drug-resistant depression.

　　45. The passage mainly ______.
　　A. reports a discovery
　　B. challenges a discovery
　　C. explains the problem with a discovery
　　D. describes the background of a discovery

　　Passage 2

　　During the years of the Depression (經(jīng)濟(jì)危機(jī)) in a small southeastern Idaho community, I used to stop by Brother Miller’s roadside stand for farm-fresh produce as the season made it available. Food and money were still extremely scarce and bartering was used, extensively.

　　One particular day Brother Miller was bagging some early potatoes for me. I noticed a small boy, delicate of bone and feature, ragged but clean, hungrily looking at a basket of freshly picked green peas. I paid for my potatoes but was also drawn to the display of fresh green peas. I couldn’t help overhearing the conversation between Brother Miller and the ragged boy next to me.

　　“Hello Barry, how are you today?”

　　“Hello, Mr. Miller. Fine, thank ya. Just admiring them peas, sure look good.”

　　“They are good, Barry. How’s your Ma?”

　　“Fine. Getting stronger all of the time.”

　　“Good. Anything I can help you with?”

　　“No, Sir. Just admiring them peas.”

　　“Would you like to take some home?”
　　
　　“No, Sir. Got nothing to pay for ’em with.”

　　“Well, what have you to trade me for some of those peas?”

　　“All I’ve got is my prize marble here.”

　　“Is that right? Let me see it.”

　　“Here ’tis. She’s great!”

　　“I can see that. Hmmmm, only thing is this one is blue and I sort of go for red. Do you have a red one like this at home?”

　　“Not exactly ... but, almost.”

　　“Tell you what. Take this sack of peas home with you and next trip this way let me look at that red marble.”

　　“Sure will. Thanks, Mr. Miller.”

　　Mrs. Miller, who had been standing nearby, came over to help me. With a smile she said, “There are two other boys like him in our community, all three are in very poor circumstances. Jim just loves to bargain with them for peas, apples, tomatoes or whatever. When they come back with their red marbles, and they always do, he decides he doesn’t like red after all and he sends them home with a bag of produce for a green marble or an orange one, perhaps.”

　　I left the stand, smiling to myself, impressed with this man. A short time later I moved to Utah, but I never forgot the story of this man, the boys and their bartering.

　　Several years went by, each more rapid than the previous one. Just recently I had occasion to visit some old friends in that Idaho community and while I was there I learned that Brother Miller had died.

　　They were having his viewing (追思會(huì) ) that evening and knowing my friends wanted to go, I agreed to accompany them. Upon our arrival at the mortuary (殯儀館) we fell into line to meet the relatives of the deceased and to offer whatever words of comfort we could. Ahead of us in line were three young men. One was in an army uniform and the other two wore nice haircuts, dark suits and white shirts ... very professional looking.

　　They approached Mrs. Miller, standing there smiling and calm. Each of the young men hugged her, kissed her on the cheek, spoke briefly with her and moved on to the coffin. Her misty light blue eyes followed them as, one by one, each young man stopped briefly and placed his own warm hand over the cold pale hand in the coffin. Each left the mortuary, awkwardly, wiping his eyes.

　　Our turn came to meet Mrs. Miller. I told her who I was and mentioned the story she had told me about the marbles. Eyes glistening, she took my hand and led me to the coffin. “Those three young men, that just left, were the boys I told you about. They just told me how they were grateful for the things Jim “traded” them. Now, at last, when Jim could not change his mind about color or size ... they came to pay their debt. We’ve never had a great deal of the wealth of this world,” she confided, “but, right now, Jim would consider himself the richest man in Idaho.”

　　With loving gentleness she lifted the lifeless fingers of her deceased husband. Resting underneath were three, magnificently shiny, red marbles.

　　46. In Paragraph 1, “bartering” probably means ______.
