1、Happy Marriage, Happy HeartHappily married people have lower blood pressure ____ unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily 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 marriage," study author Julianne 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 for 24 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 or two 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 doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】

2、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. To make electrochromic windows change color, what is applied to the window glass? 【单选题】

A. Electricity.

B.Tungsten oxide.

C.A battery.

D.A voltage.

正确答案:B

答案解析:第五段第二句提供了答案。a sheet of glass coated with thin layers of chemical compound such as tungsten oxide中的coated是“涂上一层薄薄的……”的意思。

4、Cars Are Good for the Environment，HonestBritain\'s motor industry is planning a major publicity campaign to counter what it sees as an official anti-car bias and to improve the environmental image of the cars, according to documents leaked to the pressure group, Friends of the Earth (FOE). The five-year campaign could cost up to ￡12 million.The internal document which was produced last month by the Society of Motor Manufacturers and Traders, says that the "ultimate objective of the campaign must be to protect the long-term commercial freedom of the motor industry and the lifestyle freedom of car users". The campaign will highlight the motor industry\'s efforts to reduce emissions of carbon dioxide. European car manufacturers have already agreed with the European Com mission to reduce CO2 emissions from new cars by 25 percent to target of 140 grams per kilometer by 2008. However, the document also reveals that the industry is someway from meeting the target. ____To help control these emissions, the government has proposed replacing the flat rate annual tax on cars with a tax related to engine size so that owners of large gas-guzzler would pay more than owners of small cars. But the motor industry opposes taxes on persons owning cars preferring taxes on use.Richard Barnet, the society\'s media manager, says: "We will work with the government to practice a practical system. " But Ian Willmore of FOE says the industry “may pose as partners of the government, but its real intention is to frustrate serious attempts to reduce traffic levels”.【单选题】

5、The Value of MotherhoodIn shopping malls, the assistants try to push you into buying "a gift to thank her for her unselfish love". When you log onto a website, a small pop-up invites you to book a bouquet for her. Commercial warmth and gratitude are the atmosphere being spread around for this special Sunday in May.____ The popularity of Mother\'s Day around the world suggests that Jarvis got all she wanted. In fact, she got more enough to make her horrified.According to a research by the US card company Hallmark, 96 percent of American consumers celebrate the holiday. They buy, among other things, 132 million cards. Mother\'s Day is the No. 1 holiday for flower purchases. Then there are the various commodities, ranging from jewelry and clothes to cosmetics and washing powder that take advantage of the promotion opportunities. Because of this, Jarvis spent the last 40 years of her life trying to stop Mother\'s Day. One protest against the commercialization of Mother\'s Day even got her arrested for disturbing the peace, interestingly.But what\'s more, commercialism changes young people\'s attitude towards motherhood. As Ralph Fevre, a reporter at the UK newspaper The Guardian, observe, traditionally "motherhood is something that we do because we think it\'s right." But in the logic of commercialism, people need something in exchange for their time and energy. A career serves this purpose better.being encouraged to pursue any career they desire. So they work hard and play hard. Becoming a mother, however, inevitably handicaps career anticipation.motherhood has suffered a huge drop in status since the 1950s. According to the Guardian, there are twice as many child-free young women as there were a generation ago. Or, they put off the responsibility of parenting until later in their lives.So, Fevre writes that the meaning of celebrating Mother\'s Day needs to be updated: "It is to persuade people that parenting is a good idea and to honor people for their attempt to be good people."【单选题】

A.The American version of Mother\'s Day was thought up as early as 1905, by Anna Jarvis, as a way of recognizing the real value of motherhood.

B.But what\'s more, commercialism changes young people\'s attitude towards motherhood.

C.Obviously, the best girl will be a phone call or a visit.

D.According to a research by the US card company Hallmark, 96 percent of American consumers celebrate the holiday.

E.As a result, motherhood has suffered a huge drop in status since the 1950s.

F.In addition, women are being encouraged to pursue any career they desire.

正确答案:A

答案解析:第一段主要讲笼罩着母亲节的商业气氛，如服务员让你买一件礼物送给你的母亲，表示你感谢她无私的爱等。从语气上可以看出，作者对用商业手段表达母爱是反对的。第二段的第二个句子中有Anna Jarvis这个人的名字。最后一个句子是这么说的： In fact， she got more enough to make her horrified. 事实上，她得到的还要多，多得使她感到可怕。从内容的衔接来看，Anna Jarvis在前面很可能出现过。在多有的选项中只有A出现了这个名字，因此A是对的。
