1、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits ａｎｄ　daytime functioning, ａｎｄ　found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - authｏｒDaniet J. Taylｏｒsaid in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylｏｒsaid.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) ａｎｄ　a decline in college students\' academic performance.The study included 64 psychology, nursing ａｎｄ　medical students, average age 27. 4 years, who were divided into two groups—low GPAs ａｎｄ　high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks ｏｒtwitches (痉挛) at night, 65.6 percent reported waking at night ａｎｄ　having trouble falling back to sleep, ａｎｄ　72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study authｏｒDr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."According to Dr. Pagel, the academic performance of a student will be affected ______.【单选题】

A.if he ｏｒshe is not motivated

B.if he ｏｒshe is troubled by disordered sleep

C.if he ｏｒshe is a morning type

D.if he ｏｒshe is a lazy person

正确答案:B

答案解析:本题难度不大，答案依据比较明显，答案依据是文章最后一段最后一句，谈到睡眠紊乱对学生学术能力的副作用很大，包括考试成绩，回来看选项，B项和原文句意相符，是答案。

2、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people ｏｒsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit fｏｒsingles ｏｒunhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy ____," study authｏｒJulianne Holt Lunstad, a psychologist who specializes in relationships ａｎｄ　health, said in a prepared statement.The study included 204 married ａｎｄ　99 single adults who wore portable blood - pressure monitors fｏｒ24 hours. The monitors recorded blood pressure at random intervals ａｎｄ　provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one ｏｒtwo readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married ａｎｄ　single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet ａｎｄ　having regular doctｏｒvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.life

B.marriage

C.partner

D.spouse

正确答案:B

答案解析:本题难度不大，考查词义辨析，文章一开始就提到happily married people，文章此处是说“对身心健康最具保护作用的是拥有幸福的婚姻”，答案是B。

3、Smart Window Windows not only let light in to cut down an electricity use fｏｒlighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark ａｎｄ　anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professｏｒof solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows ａｎｄ　natural light are important fｏｒimproving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy ａｎｄ　temperature control. In the winter, cold air leaks in. When it\'s hot ａｎｄ　sunny, sunlight streams in. All of this sunlight carries lots of heat ａｎｄ　energy. ａｎｄ　all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a majｏｒfocus of energy research fｏｒa long time. Over the years, scientists have come up with a variety of strategies fｏｒcoating, glazing, ａｎｄ　layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. Fｏｒexample, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied ａｎｄ　dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear ｏｒdark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. What will be the benefit if the research on smart windows turns out to be successful, according to the last paragraph? 【单选题】

A.The buildings will look different.

B.Windows can be as large as you want.

C.We may not need air conditioners any more.

D.They are less expensive than traditional windows.

正确答案:C

答案解析:被选项中出现了大量的修饰词，段落最后一段的倒数第2句是直接答案相关句，根据该句内容判断C是答案。

4、Parkinson\'s Disease1. Parkinson\'s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine(多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly ａｎｄ　do what you want them to do. When you have Parkinson\'s, these nerve cells break down. Then you no longer have enough dopamine, ａｎｄ　you have trouble moving the way you want to.2. No one knows fｏｒsure what makes these nerve cells break down. But scientists are doing a lot of research to look fｏｒthe answer. They are studying many possible causes, including aging ａｎｄ　poisons in the environment. Abnormal genes seem to lead to Parkinson\'s disease in some people. But so far, there is not enough proof to show that it is always inherited.3. Tremｏｒ(颤抖) may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. Tremｏｒoften starts in just one arm ｏｒleg ｏｒonly on one side of the body. It may be worse when you are awake but not moving the affected arm ｏｒleg. It may get better when you move the limb ｏｒyou are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing ｏｒconstipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed ｏｒblank expression, trouble speaking, ａｎｄ　other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure fｏｒParkinson\'s disease. But there are several types of medicines that can control the symptoms ａｎｄ　make the disease easier to live with. You may not even need treatment if your symptoms are not obvious. Your doctｏｒmay wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctｏｒwill adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.You\'ll find it hard to move the way you want to ______.【单选题】

A.if there isn’t enough dopamine in your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed ｏｒblank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:A

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第一段最后一句，Then you no longer have enough dopamine, ａｎｄ　you have trouble moving the way you want to.谈到如果你没有足够多的多巴胺，行动就会变得困难，答案是A。

5、The IcemanOn a September day in 1991, two Germans were climbing the mountains between Austria ａｎｄ　Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, ｏｒ3 ,200 meters) , the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual ａｎｄ　so the body had come to the surface.It was lying face downward. The skeleton (骨架) was in perfect condition, except fｏｒa wound in the head, There was still skin on the bones ａｎｄ　the remains of some clothes. The hands were still holding the wooden handle of an ax ａｎｄ　on the feet there were very simple leather ａｎｄ　cloth hoots. Nearby was a pair of gloves made of tree bark (树皮) ａｎｄ　a holder fｏｒarrows.Who was this man? How ａｎｄ　when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before ａｎｄ　whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousａｎｄ　years old.With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B. C. , he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story, A new kind of X - ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage ａｎｄ　bleeding. He almost certainly died from this wound, ａｎｄ　not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, ｏｒhe may have been fighting bandits. He may even have been a bandit himself.By studying his clothes ａｎｄ　tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has given us important clues to the history of those distant times.All the following are assumptions once made about the Iceman EXCEPT ______.【单选题】

A.he was a soldier in World War I

B.he was a Swiss woman\'s long - lost father

C.he was born about a thousａｎｄ　years ago

D.he came from Italy

正确答案:D

答案解析:本题有一定难度，首先要读懂题干，好多考生因为没有读懂而做错。第三段谈到了对冰人的各种猜测：有人认为他是一战的士兵；一位瑞士女人坚信冰人是她二十年前死在山里的父亲，科学家们认为他大概有一千年的历史了，惟独没有提到冰人是意大利人的猜测，所以答案是D。
