1、Smart Window
Windows not only let light in to cut down an electricity use for lighting, 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 professor of 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 for improving 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 major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, 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. For example, 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 or dark.
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?

1、Outside-the-classroom Learning Makes a Big Difference
Putting 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 for two years.
Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining.
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 a group of 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. For example, in April, several student organizations at Wisconsin teamed up for an 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.
An extracurricular activity like raising a fund of $300,000 is risky because most student leaders ____.【单选题】

A.are lazy

B.are stupid

C.are not rich enough

D.wilt not take an interest in it

正确答案:D

答案解析:答案可以从第二段的第一句话中找到。第一句话是这么说的：大多数学生干部并不想在它们不感兴趣的事上花大量的时间。

1、The motorcar
Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.
The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements.
The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.
What is the author's attitude toward the future of autos?
【单选题】

A.Enthusiastic

B.Pessimistic

C.Optimistic

D.Cautious

正确答案:C

答案解析:从作者对计算机监控系统的使用来看，作者对自行车的前景是持乐观态度的，所以答案为C。

1、15 Million Americans Suffer from Social Anxiety Disorder
Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds.
The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports.
"Social anxiety disorder is when somebody has an intense, persistent and irrational fear of social or performance situations," Jerilyn Ross, the association's president and CEO, said during a teleconference Wednesday.
"The condition causes people to avoid common, everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves," Ross said.
Social anxiety disorder can interfere with daily routines and job performance, Ross noted. "It also makes it very difficult for people to develop friends and romantic partnerships," she said.
People with this disorder recognize their fear is excessive and irrational, Ross noted. "But they feel powerless to do anything about it," she said.
Social anxiety disorder can start in the early teens, Dr. Mark H. Pollack, director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School, said during the teleconference.
"This is a disorder that starts affecting people early on," Pollack said. "The typical age of onset is early adolescence, age 12 or 13, and many individuals report a history of anxiety dating back to earlier childhood."
The disorder also has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling and stammering, Ross said.
Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn't want people to think they were crazy, and 58 percent said they were embarrassed by their condition, Ross said.
However, when the condition is diagnosed and treated, many reported improvement in their lives. In fact, 59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship. In addition, 39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help, Ross noted.
Which is NOT true of people with social anxiety disorder?【单选题】

A.They're often isolated and ashamed.

B.They find it difficult to make friends.

C.They often fail to get timely treatment.

D.They tend to judge or criticize other people.

正确答案:D

答案解析:前三项在短文的第二段和第五段都有提及，只有第四项是错误的，他们不是常常评判或批评别人，而是害怕遭到别人的评判或批评。

1、Human Heart Can Make New Cells
Solving 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 for the 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 professor of 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 or if 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 for example, 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-author Dr. 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 door to 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.
The human heart stops producing cardiac cells____.【单选题】

A.when a person becomes old

B.as soon as a person gets sick

C.immediately after a person is born

D.once a person dies

正确答案:D

答案解析:根据是第一段中：. . . the human heart continues to generate new cardiac cells throughout the life span。在人的整个生命进程中，其心脏不断产生新的心肌细胞。言外之意，这个过程直到人死才会停止。
