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."In the first study, students who stay up late ______.【单选题】

A.had lower GPAs

B.had higher GPAs

C.performed equally well in their studies

D.had little difficulty concentrating during the day

正确答案:A

答案解析:本题有一定难度，需要吃透原文句意，答案依据在文章第二段后半部分，谈到早起的学生平均成绩高于晚睡的学生，换句话说，晚睡的学生成绩低，答案是A。

2、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. When are windows the weak link in a building? 【单选题】

A. In the cold winter.

B.In the hot summer.

C.When air conditioners are turned on.

D.Both A ａｎｄ　B.

正确答案:D

答案解析:短文第三段的第一句说：windows are the weak link in a building，接下来是对这句话分寒冬和炎夏做了说明，所以D是正确选择。

3、Outside-the-classroom Learning Makes a Big DifferencePutting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky. When you consider the fact that the money is supposed to be given to. Children in need of medical care, you might call the idea crazy.Most student leaders don\'t want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon\'s operations officer fｏｒtwo years.Yvonne Fangmeyer, directｏｒof the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire fｏｒfriendship was the most frequently cited reason fｏｒjoining.At large universities like Fangmeyer\'s, which has more than 40,000 students, the students, first of all, want to find a way to "belong in their own comer of campus".Katie Rowley, a Wisconsin senior, confirms the survey\'s findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find aｇｒｏｕｐof friends. "All of this talk of friendship, however, does not mean that students aren\'t thinking about their resumes. "I think that a lot of people do join to \'fatten up their resume\'," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles. "But without passion student leaders can have a difficult time trying to weather the storms that come. Fｏｒexample, in April, several student organizations at Wisconsin teamed up fｏｒan event designed to educate students about homelessness ａｎｄ　poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, ａｎｄ　dealing with the university\'s complicated bureaucracy."Outside-of the classroom learning really makes a big difference," Fangmeyer said.The phrasal verb fatten up in paragraph 6 could be best replaced by ____.【单选题】

A.invent

B.rewrite

C.polish

D.complete

正确答案:C

答案解析:“fatten up”原意是“使人或动物变肥”，在这里可以解释为使一个人的履历更充实一些也好看一些，因此意思上最接近的是“polish”（润色）。

4、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age. The finding, published in the April 3 issue of Science, could open a new path fｏｒthe treatment of heart diseases such as heart failure ａｎｄ　heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professｏｒof stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with ｏｒif they could be renewed," he said. The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with age to only 0. 45 percent by age 75, "If we can understａｎｄ　how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after fｏｒexample, a heart attack, "Frisen said. That could lead to treatment that helps restore damaged hearts. A lot of people suffer from chronic heart failure," noted co-authｏｒDr. Ratan Bhardwaj. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the doｏｒto potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new ａｎｄ　more cells to overcome the problem they are facing. " But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.It is not known yet if the rate of cell turnover in diseased hearts____. 【单选题】

A.s high enough to replace cells faster than they re dying off

B.is of any use to researchers

C.is the same as that in healthy hearts

D.changes over time

正确答案:C

答案解析:最后一句说：心脏产生的新细胞的数量是按照健康心脏计算的，而有心脏病的细胞更替率是否与健康心脏相同还不得而知。

5、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum fｏｒcancer patients to swap (变换) stories ａｎｄ　share experiences on how to cope with such a devastating disease.But Cancer Chat is a forum with a difference: it has an information safety net.This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" ｏｒscientifically unsound information.Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.ａｎｄ　Rebekah Gibbs, cancer patient ａｎｄ　star of TWs Casualty, has pledged her support fｏｒthe new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer ａｎｄ　I have had such a heart - warming response from other people going through the same thing."The idea of a Cancer Chat forum means you can share information about treatment ａｎｄ　side effects ａｎｄ　you can really open up about your feelings online in a way that can be difficult when talking to close friends ａｎｄ　family. ａｎｄ　with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients ａｎｄ　their families 6,000 pages of up - to - date information that is easy to understａｎｄ　ａｎｄ　explains a wide range of treatments fｏｒdifferent types of cancer ａｎｄ　gives details of clinical trials. There is also a UK ｄａｔａｂａｓｅ of cancer clinical trials.The award - winning website attracts around one million visitors a month ａｎｄ　Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.Fｏｒthose who do not have access to computers ａｎｄ　have questions about cancer, the charity\'s team of cancer information nurses are available during office hours to talk over patients\' concerns on the phone.Which statement about the CancerHelp UK website is NOT true?【单选题】

A.It offers lots of information on cancer treatment ａｎｄ　clinical trials.

B.It attracts numerous visitors.

C.It has won an award.

D.It is accessible only to British citizens.

正确答案:D

答案解析:本题有一定难度，需要认真吃透原文句意，找出判断依据。认真阅读文章可以发现，选项里A，B，C三项在文中都提到了，第四段第一句，谈到任何人都可以上该论坛的网站浏览消息，Cancer Help UK是其子网站，但并没有提到只有英国公民才能登陆该网站，答案是D。
