　　第一篇 Face Masks May Not Protect from Super-Flu

　　IF a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help, or harm, during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case.

　　But its a question the public keeps asking while the government are making preparations for the next flu pandemi

　　C. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. We dont want people wearing them everywhere, said the CD

　　C. The overall recommendation really is to avoid exposure.

　　When thats not possible, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, youre healthy and cant avoid going to a crowded place. Second t youre sick and think you may have close contact with the healthy, such as a family member checking on you. Third, you live with someone whos sick and thus might be in the early stages of infection, but still need to go out.

　　Influenza pandemics can strike when the easy-to-mutate flu virus shifts to a strain that people never have experience

　　D. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person.

　　During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close contact with the sick unless you must care for someone. Why arent masks added to this self-protection list? Because they can help trap virus-laden droplets flying through the air with a cough or sneeze. Simple surgical masks only filter the larger droplets. Besides, the CDC is afraid masks may create a false sense of security. Perhaps someone who should have stayed home would don an ill-fitting mask and hop on the subway instead.

　　Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand, then touches a doorknob or subway pole. If you touch that spot next and then put germy hands on your nose or mouth, youve been expose

　　D. Its harder to rub your nose while wearing a mask and so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the nose. These are the problems face masks may create for their users.

　　Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing.

　　31. What is the passage mainly about?

　　A. Widespread use of face masks.

　　B. Possibility of a worldwide flu outbreak

　　C. New discoveries of a face mask research.

　　D. Effectiveness of wearing face masks

　　32. The CDC suggests that people

　　A. stay alone when being sick.

　　B. wear face masks when going to a crowded place.

　　C. wear face masks wherever possible.

　　D. remain at home if living with someone whos sick.

　　33. The word that in Paragraph 3 refers to

　　A. making preparations.

　　B. avoiding exposure

　　C. coming up with guidelines.

　　D. wearing face masks everywhere.

　　34. Which of the following statements is true?

　　A. Scientists warn the next flu is coming soon.

　　B. Asian bird flu is spreading easily from person to person.

　　C. Masks protect people because they keep viruses away.

　　D. Masks are not effective if a flu strikes.

　　35. One of the concerns the CDC has is that

　　A .masks may give people a wrong assumption of being safe.

　　B. the sick may not wear masks and go out.

　　C. flu virus may spread via public transportation.

　　D. healthy people may not know how to protect themselves.

　　第二篇 Whats killing the Bats

　　First it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats (Myotis lucifugus,) but other species, such as the long-eared bat, the small-footed hat, the eastern pipistrelle, and the Indiana bat have also been affecte

　　D. In some caves, more than 90 percent of the bat populations have died.

　　One possibility is disease. A white fungus (真菌)known as fusarium has been found on the noses of both living and dead bats. However, scientists dont know If the fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions.

　　Another possible cause is a lack of foo

　　D. For example, bats typically eat a large number of moths (蛾), and in some states such as New York, the number of moths has been declining in recent years. If bats cant eat enough food, they starve to death.

　　Still other scientists believe that global warming is to blame. Warmer temperatures in recent years have been waking up hibernating (冬眠)bats earlier than usual. If bats break their hibernation at the wrong time, they might not find their expected food sources. The weather might also turn cold again and weaken or kill the bats.

　　Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences. Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects in an hour. They also eat beetles and other insects that damage plant crops. If there arent enough bats, damage will be great from the insects they eat While bats live a long time for their size 一 the little brown bat can live for more than 30 years 一 a female bat has only one baby per year, so bat populations grow slowly. Many bat species in the United States are already protected or endangered.

　　How can you help? Do not disturb sleeping or nesting bats. If you discover bate that seem to be sick or that are dead, contact your local Fish Wildlife Department with the details. However, be careful not to touch the animals.

　　36. What is the main idea of this passage?

　　A. All species of bats in North America are dying.

　　B. Scientists already know the cause of the deaths of bats

　　C. The bat deaths are a serious problem.

　　D. There are many possible causes of the deaths of bats.

　　37. What does the first sentence in Paragraph 1 mean?

　　A. Bees have been dying mysteriously.

　　B. The first article on the website is about bees.

　　C. Bees usually die before bats.

　　D. It was bees that caused the deaths of bats.

　　38. The word pipistrelle in Paragraph 1 refers to

　　A. a kind of fungus.

　　B. an area in the U.S.

　　C. a special cave.

　　D. a kind of bat.

　　39. The moths in Paragraph 3 are taken as an example of

　　A. diseases that kill bats.

　　B. Insects that bats eat.

　　C. animals that have diseases.

　　D. bat species that are starving to death.

　　40. What is the purpose of the last paragraph?

　　A. To get people to stop killing bats.

　　B. To hire workers for the Fish Wildlife Department.

　　C. To ask people not to touch dead bats.

　　D. To tell the public how to help bats.

　　第三篇 Better Solar Energy Systems: More Heat, More Light

　　Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but until now they havent been very good at the heat-generating part compared to a stand-alone solar thermal collector. Thats because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isnt a very efficient way to gather heat.

　　Thats a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And its also a space problem： photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications.

　　In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from ThinSilicon in California and Michael Pathak and Stephen Harrison from Queens University, Canada.

　　Most solar panels are made with crystalline silicon， but you can also make solar cells out of amorphous silicon, commonly known as thin-film silicon. They dont create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon, they have a greener footprint. Unfortunately，thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.

　　That means that their efficiency drops when you expose them to light pretty much the worst possible effect for a solar cell, Pearce explains，which is one of the reasons thin-film solar panels make up only a small fraction of the market.

　　However, Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type of PVT. You dont have to cool down thin-film silicon to make it work. In fact，Pearces group discovered that by heating it to solar-thermal operating temperatures，near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the cell once a day，they boosted the solar cells electrical efficiency by over 10 percent.

　　41. PVTs are not efficient in

　　A. creating electricity.

　　B. cooling silicon solar cells.

　　C. generating heat.

　　D. powering solar thermal collectors.

　　42. One of the problems PVTs have is that

　　A. their thermal applications are costly.

　　B. they are too expensive to afford.

　　C. they occupy too much space.

　　D. it is hard to fix them on the roof.

　　43. Which of the following is NOT mentioned as an advantage of thin-film silicon solar cells?

　　A. They are electrically efficient.

　　B. They are less expensive.

　　C. They are flexible.

　　D. They are environment friendly.

　　44. Thin-film solar panels do not sell well on market because

　　A. their advantages are not well-recognized.

　　B. they do not work well if exposed to light.

　　C. they need improving in appearance.

　　D. they are not advertised.

　　45 Which of the following statements is true?

　　A. Thin-film silicons electrical efficiency improves when heated up.

　　B. New techniques have been developed to produce thin-film silicon.

　　C. Thin-film silicon works efficiently at low temperature.

　　D. A new material enlarging the Staebler-WronsKi effect has been created.

　　第一篇 更有效的太陽(yáng)能系統(tǒng)：更多熱量，更強(qiáng)燈光

　　太陽(yáng)能光伏熱能系統(tǒng)，也叫PVT，能夠生成熱量和電能。與太陽(yáng)熱能單機(jī)收集器相比，傳統(tǒng)太陽(yáng)能光伏熱能系統(tǒng)在轉(zhuǎn)換熱能方面效率不是很高。原因是，為了使晶體硅太陽(yáng)能電池冷卻，該系統(tǒng)在低溫下工作。因此，硅體能產(chǎn)出更多的電能，卻不能有效地產(chǎn)生熱量。

　　第一，經(jīng)濟(jì)問(wèn)題。好的太陽(yáng)能熱水系統(tǒng)比太陽(yáng)能電力系統(tǒng)收集的能量更多，而且成本低得多。第二，空間問(wèn)題。光電管占去屋頂?shù)乃械目臻g，幾乎沒(méi)有空間留給熱能的產(chǎn)出。

　　在一項(xiàng)研究中，材料科學(xué)與工程副教授Joshua Pearce找到了一個(gè)解決方案：用另外一種硅制成PVT來(lái)解決效能問(wèn)題。他的合作者有：來(lái)自加利福尼亞ThinSilicon的Kunal Girotra和加拿大皇后大學(xué)的Michael Pathak和Stephen Harrison。

　　大部分太陽(yáng)能電池板是由晶體硅制成，但是，你也可以用非晶硅制成太陽(yáng)能電池，這種非晶體硅通常被叫作薄膜硅。它們不能產(chǎn)生那么多的電能，但是更 亮、更靈巧、成本更低。而且，由于它們需要的硅較少，它們更環(huán)保。不幸的是，薄膜硅太陽(yáng)能電池易受SWE效應(yīng)攻擊(在光的照射下，非晶硅氫的導(dǎo)電性短時(shí)間 內(nèi)顯著衰退，這種特性被稱為SWE效應(yīng))。

　　當(dāng)被暴露在光線下，那就意味著它們的能效會(huì)降低這幾乎是太陽(yáng)能電池最可能糟糕的效應(yīng)。Pearce解釋道。這就是薄型太陽(yáng)能板只占有一少部分市場(chǎng)的原因。

　　然而，Pearce和他的團(tuán)隊(duì)把薄膜硅合成為一種新型的PVT，可以克服或繞過(guò)SWE效應(yīng)。這種方法可以不用冷卻薄膜硅而讓它們產(chǎn)生效能。事實(shí) 上，Pearce團(tuán)隊(duì)發(fā)現(xiàn)，通過(guò)把薄膜硅加熱到太陽(yáng)熱能操作溫度，即臨近水的沸點(diǎn)，可以把它制成較厚的電池，從而可以遏制SWE效應(yīng)。當(dāng)把薄膜硅直接應(yīng)用 到太陽(yáng)熱能集熱器時(shí)，他們也發(fā)現(xiàn)，如果一天把太陽(yáng)能電池加熱一次，那么太陽(yáng)能的電力效能會(huì)增加10%。
