1、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. 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。

2、The Need to RememberSome people say they have no memory at all: "I just can\'t remember a thing!" But of course we all have a memory. Our memory tells us who we are. Our memory helps U. S. to make use in the present of what we have learnt in the past.In fact we have different types of memory. Fｏｒexample, our visual memory helps us recall facts ａｎｄ　places. Some people have such a strong visual memory that they can remember exactly what they have seen, fｏｒexample, pages of a book, as a complete picture.Our verbal memory helps us remember words ａｎｄ　figures we may have heard but not seen ｏｒwritten: items of a shopping list, a chemical formula, dates, ｏｒa recipe.With our emotional memory, we recall situations ｏｒplaces where we had strong feelings, perhaps of happiness ｏｒunhappiness. We also have special memories fｏｒsmell, taste, touch ａｎｄ　sound, ａｎｄ　fｏｒperforming physical movements.We have two ways of storing any of these memories. Our short-term memory stores items fｏｒup to thirty seconds-enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items fｏｒa lifetime. Older people in fact have a much biter long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance of when they were very young.Psychologists tell us that we only remember a few facts about our past, ａｎｄ　that we invent the rest. It is as though we remember only the outline ofa story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past, ｏｒmaybe victims needing sympathy.Animals do not have a long-term memory.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:关键词是：long-term memory. 在第五段中我们发现谈到了长期记忆和短期记忆，但没有讲到动物是否具有长期记忆。

3、MemoriesMost episodes of absent-mindedness forgetting where you left something ｏｒwondering why you just entered a room are caused by a simple lack of attention, says Schacter. "You are supposed to remember something, but you haven\'t encoded it deeply."Encoding, Schacter says, is a special way of paying attention to an event that has a majｏｒimpact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, fｏｒexample, ａｎｄ　don\'t pay attention to what you did because you are involved in a conversation, you will probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn\'t failing you," says Schacter. " Rather, you didn\'t give your memory system the information it needed. "____. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to ｄｒｅｐa letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, ａｎｄ　memory relies on just that.Visual cues can help prevent absent-mindedness, says Sclnacter." But be sure the cue is clear ａｎｄ　available.,"he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table don\'t leave it in the medicine chest ａｎｄ　write yourself a note that you keep in a pocket.Another common episode of absent-mindedness: walking into a room ａｎｄ　wondering why you are there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, ａｎｄ　you will likely remember.【单选题】

4、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 marriage," 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 ____ 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.pressure

B.speed

C.level

D.flow

正确答案:A

答案解析:本题难度不大，考查词义辨析。前面已经出现了blood，文章讨论的是婚姻和血压的关系，很明显，文章此处应该填pressure，答案是A。

5、Cancer1. Cancer is aｇｒｏｕｐof many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally, cells grow ａｎｄ　divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, ａｎｄ　old cells do not die when they should. The extra cells form a mass of tissue called a growth ｏｒtumｏｒ肿瘤). Benign(良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal ａｎｄ　divide without control ｏｒorder.2. Scientists have learned that cancer is caused by changes in genes that normally control the growth ａｎｄ　death of cells. Certain lifestyle ａｎｄ　environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet(紫外线的) radiation from the sun, ｏｒexposure to carcinogens (致症物) in the workplace ｏｒin the environment. Some gene alterations are inherited.3. Cancer treatment can include surgery, radiation therapy, chemotherapy(化疗), hormone therapy, ａｎｄ　biological therapy. The doctｏｒmay use one method ｏｒa combination of methods, depending on the type ａｎｄ　location of the cancer, whether the disease has spread, the patient\'s age ａｎｄ　general health ａｎｄ　other factors. Because treatment fｏｒcancer can also damage healthy cells ａｎｄ　tissues, it often causes side effects. Patients ａｎｄ　doctors generally discuss the treatment options, weighting the likely benefits of killing cancer cells ａｎｄ　the risks of possible side effects.4. Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease ａｎｄ　the patient\'s tolerance fｏｒpain. Most pain occurs when the cancer grows ａｎｄ　presses against bones, organs, ｏｒnerves. Pain may also be a side effect of treatment. However, pain can generally be relieved ｏｒreduced with prescription medicines ｏｒover - the - counter drugs recommended by the doctor.Paragraph 3 ______【单选题】
