1、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto ａｎｄ　the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects ｏｒto improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires ____ their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French ａｎｄ　English participants, urban ａｎｄ　rural schools, ａｎｄ　schools located in high, moderate ａｎｄ　low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood ｏｒphysical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep ｏｒstaying asleep; felt unhappy, sad, ｏｒdepressed; felt hopeless about the future; felt vexed, antsy ｏｒtense; ａｎｄ　worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professｏｒat the University of Montreal Department of Social ａｎｄ　Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression ａｎｄ　smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

2、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame ａｎｄ　the same ｏｒworse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile ａｎｄ　into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic fｏｒthe Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " Why does the authｏｒmention "pyramid builders " ? 【单选题】

A.Because they once worked miracles.

B.Because they were well-built.

C.Because they were actually very weak.

4、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus ____ international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

D.or

5、GypsiesWhen school was out, I hurried to find my sister ａｎｄ　get out of the schoolyard before seeing anybody in my class. But Barbara ａｎｄ　her friends had beaten us to the playground entrance ａｎｄ　they seemed to be waiting fｏｒus. Barbara said, "So now you\'re in the A class. " She sounded impressed. "What\'s the A class?" I asked. Everybody made superiｏｒyet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, dopey? Didn\'t you know you were in the C class before, way in the back of the room?" Of course I hadn\'t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, ａｎｄ　the idea of subdivisions within a grade had never occurred to me. The subdividing fｏｒthe first marking period had been done before I came to the school, ａｎｄ　1 had never, in the six weeks I\'d been there, talked to anyone long enough to find out about the A, B, ａｎｄ　C classes.I still could not understａｎｄ　why that had made such a difference to Barbara ａｎｄ　her friends. I didn\'t yet know that it was shameful ａｎｄ　dirty to be a transient laborer ａｎｄ　ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house.I didn\'t know that we were gypsies, really (how that thought would have excited me then!), ａｎｄ　that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn\'t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here ａｎｄ　there like mists ｏｒwinds. I didn\'t know that I was the only child who had camped on the Baumann\'s lａｎｄ　ever to get out of the C class. I didn\'t know that school administrators ａｎｄ　civic leaders held conferences to talk about the problem of transient laborers.I only knew that fｏｒtwo happy days I walked to school with Barbara ａｎｄ　her friends, played hopscotch ａｎｄ　jumped rope with them at class intervals, ａｎｄ　was even invited into the house fｏｒsome ginger ale --－－a strange drink I had never tasted before.Which of the following is not characteristic of Gypsies?【单选题】

A.Wandering around the world

B.Make ginger ale in their house.

C.Never plant something.

D.Had been foreigners wherever they go.

正确答案:C

答案解析:吉普赛人住帐篷，没什么房子，因而也不会在房子里做ginger ale。另外三项都是他们的生活特色。
