Theyre all disease caused by viruses，tiny microorganisms that can pass from person to person. Its no wonder1 that when most people think about viruses, finding w

7、ays to steer clear of2 viruses is whats on peoples minds. 水痘、普通感冒、流感和艾滋病有哪些相似之处呢？这些都是由病毒引起的疾病。病毒是能够在人与人之间传染的微生物。难怪大部分人一提到病毒，首先想到的是如何躲避病毒。Not everyone runs from the tiny disease carriers, though3.In Cambridge，Massachusetts4, scientists have discovered that some viruses can be helpful in an unusual wa

8、y. They are putting viruses to work，teaching them to build some of the worlds smallest rechargeable batteries. 然而，并不是每个人都躲避这些病毒携带者。在马萨诸塞州剑桥市，科学家发现有些病毒能起到非同寻常的作用。他们使病毒开始工作，使病毒构成世界上最小的充电电池。Viruses and batteries may seem like an unusual pair, but theyre not so strange for engineer Angela Belcher, who f

9、irst came up with5 the idea. At the Massachusetts Institute of Technology (MIT) in Cambridge，she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries，the scientists combine what they know about biology，technology and production techniq

10、ues.病毒和电池的搭档似乎并不常见，但这对于工程师安吉拉贝尔彻来说却并不陌生。安吉拉贝尔彻最早产生了这一想法。在位于剑桥市的麻省理工学院，她和合作者一起用新方式融合了不同的科学领域。在由病毒构成的电池里，科学家融合了他们在生物、技术和生产工艺方面的知识。Belchers team includes Paula Hammond，who helps put together the tiny batteries，and Yet-Ming Chiang, an expert on how to store energy in the form of a battery. Were working

11、on things we traditionally dont associate with nature, says Hammond. 贝尔彻的团队包括帮助组装微型电池的宝拉哈蒙德和以电池形式存储能量的专家蒋业明。哈蒙德说，“我们现在从事的行业是传统中不会想到的。”Many batteries are already pretty small. You can hold A，C and D batteries6 in your hand. The coin-like batteries that power watches are often smaller than a penny. Ho

12、wever，every year，new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink，ordinary bakeries wont be small enough to fit inside. 许多电池已经很小了。A型、C型和D型电池都可以握在手里。硬币形状的手表电池通常比分币还小。然而，个人音乐播放器和手机等新型电子设备变得越来越小。这些设备变小了，普通电池就无法安装进去了。The ideal ba

13、ttery will store a lot of energy in a small package. Right now，Belchers model battery，a metallic disk completely built by viruses，looks like a regular watch battery. But inside，its components are very small-so tiny you can only see them with a powerful microscope. 理想的电池应当体积小、储能多。现在，贝尔彻的电池模型是完全由病毒构成的

14、金属圆盘，看起来就像普通手表电池。但里面的部件却非常小小到用高倍望远镜才能看到。How small are these battery parts? To get some idea of the size，pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is-pretty thin，right? Although the width of each persons hair is a bit different，you coul

15、d probably fit about 10 of these virus-built battery parts，side to side，across one hair. These microbatteries may change the way we look at viruses7. 这些电池部件到底有多小呢？从头上拔一根头发，把它放到白纸上，看看头发的宽度是不是很细呢？尽管每个人的头发宽度不同，每个头发上可以并列排放大约10个病毒电池部件。这些为电池能会改变我们对病毒的看法。词汇： chicken pox水痘 collaborator n.合作者，协作者 microorgani

16、sm n.微生物 pluck v.拔，摘，采 metallic adj.金属的 注释： 1.no wonder：不足为奇的，难怪 2.steer clear of：避开，绕开 3.though：意思为“然而，可是”。在句中使用时通常放在句末。4.Cambridge，Massachusetts：马萨诸塞州的剑桥市。本文第三段提到的the Massachusetts Institute of Technology(MIT)in Cambridge即指坐落于剑桥市的麻省理工学院。麻省理工学院于1861年由著名自然科学家威廉巴罗吉杰斯创立。这是美国的一所私立研究型大学，培养高级科技人才和管理人才，是以

17、理工科为主的、世界一流的综合性大学。5.came up with：提出6.A，C and D batteries：A、C、D均为电池型号。 7.These microbatteries may change the way we look at viruses：这些微型电池可能会改变我们看待病毒的方式。作者想表达的意思是：人们一直认为病毒有害无益，现在病毒可用来制作电池，人们对病毒的看法可能会因此而发生变化。 练习： 1.According to the first paragraph，people try to A.kill microorganisms related to chicken

18、 pox，the flu，etc. B.keep themselves away from viruses because they are invisible. C.stay away from viruses because they are causes of various diseases. D.cure themselves of virus-related diseases by taking medicines. 2.What is Belchers team doing at present? A.It is finding ways to get rid of viruse

19、s. B.It is mass-producing microbatteries. C.It is making batteries with viruses. D.It is analyzing virus genes. 3.What expression below is opposite in meaning to the word shrink appearing in paragraph 5 ? A.Broaden. B.Spread. C.Extend. D.Expand. 4.Which of the following is true of Belchers battery m

20、entioned in paragraph 6? A.It is made of metal. B.It is a kind of watch battery. C.It can only be seen with a microscope. D.It is a metallic disk with viruses inside it. 5.How tiny is one battery part? A.Its width is one tenth of a hair. B.It equals the width of a hair. C.It is as thin as a piece of

21、 paper. D.Its width is too tiny to measure. 答案与题解：1.C 短文第一段的大致意思是，许多疾病都由病毒引起，诸如水痘、感冒和艾滋病，所以人们想尽办法躲避病毒。这是C所表达的意思。A不是正确选择，因为文章并没有说人们想方设法去杀死病毒。B的后半句的内容(病毒肉眼看不见)和D的内容(吃药治疗病毒引起的疾病)文中没有提到。 2.C短文的第二段明确提供了答案。3.D 根据上下文，shrink在此的意思是“收缩，即“缩小。所以，它的反义词是expand(增大，扩张)。C不是正确选择，因为extend的意思是become longer，即“延伸”或“加长。A的

22、意思是“加宽”，也不是答案。B的意思是“伸展，展开，在一定的上下文里也可以做shrink的反义词，但在第五段这个语境里，B不是最佳选择。4.D 第六段第二句中提到的metallic disk是指“金属圆盘”，它是微型电池的外形，其内部是由病毒构成的电池部件。微型电池不是由金属组成的，所以A不是答案。本段提到，这种电池looks like a regular watch battery，与手表里电池外形相似，但并不等同手表电池，所以B也不是正确选择。文章只是说电池的部件(但并没有说整个电池)小到只能用显微镜才能看到，所以C也不是正确的选择。D才是第六段所要表达的主要内容，因此是答案。 5.A 短

23、文最后一段的第四句(“you could probably fit about 10 of these virus-built battery parts，side to side，across one hair”)提供了本题的答案。返回+第三十五篇 Putting Plants to Work （植物效能 2013理工B真题）Using the power of the sun is nothing new. People have had solar-powered calculators and buildings with solar panels for decades. But p

24、lants are the real experts : Theyve been using sunlight as an energy source for billions of years.太阳能的使用已经不足为奇。几十年前，人们就开始使用太阳能计算器，制造太阳能电热板镶嵌的建筑。但是植物当属应用太阳能的专家：十亿年来，植物一直把阳光作为能源资源。Ceils in the green leaves of plants work like tiny factories to convert sunlight, carbon dioxide, and water into1 sugars a

25、nd starches, stored energy that the plants can use. This conversion process is called photosynthesis. Unfortunately, unless youre a plant, its difficult and expensive to convert sunlight into storable energy. Thats why scientists are taking a closer look at exactly how plants do it.绿叶植物细胞的工作就像微型加工厂一

26、样，将阳光，二氧化碳和水转化为糖和淀粉，并且同时储存植物本身所需的能量。这种转换过程叫做光合作用。可惜你不是一株植物，必须困难的并且花上大价钱将阳光转换为稳定的能源。因此，科学家们正在对植株进行准确细致的研究。Some scientists are trying to get plants, or biological cells that act like plants, to work as miniature photosynthetic power stations. For example, Mafia Ghirardi of the National Renewable Energ

27、y Laboratory in Golden, Colo. 2, is working with green algae3. Shes trying to trick them into producing hydrogen4 instead of sugars when they perform photosynthesis. Once the researchers can get the algae working efficiently, the hydrogen that they produce could be used to power fuel Cells in cars o

28、r to generate electricity.一些科学家正试图像植物的作用过程一样，将植物，或生物的细胞活动看做微型光合发电站。例如，玛丽亚奇若蒂在美国科罗拉多州的国家可再生能源实验室里对绿藻进行研究。她正想方设法的通过植物的产生氢来取代光合作用产生的糖。一旦研究人员了解藻类如何有效率的进行工作，由此产生的氢气可用于燃料电池动力汽车和发电。The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab. During photosynthesis, plants normally make

29、 sugars or starches. But under certain conditions, a lot of algae are able to use the sunlight energy not to store starch, but to make hydrogen. Ghirardi says. For example, algae will produce hydrogen in an air free environment. Its the oxygen in the air that prevents algae from making hydrogen most

30、 of the time.在实验室里，藻类生长通过狭窄的颈玻璃瓶生产氢气的环境下。在光合作用下，植物通常产生糖类或淀粉。奇若蒂说：“但在一定条件下，有很多藻类能够利用日光能源产生氢气而不是储存淀粉。”例如，藻类会在空气存在环境下产生氢气。这是因为空气中的氧气，氧阻止绿藻制造氢。Working in an air free environment, however, is difficult. Its not a practical way to produce cheap energy. But Ghirardi and her colleagues have discovered that

31、by removing a chemical called sulfate from the environment that the algae grow in, they will make hydrogen instead of sugars, even when air is present.藻类在空气中虽然可以工作，但是充满困难。这种方式不能切实可行的生产廉价的能源。但是奇若蒂和她的同事们已经发现，即使在目前的空气条件下，他们从藻类生长的环境中，除去所谓的硫酸化学品，能够产生氢来代替糖。Unfortunately, removing the sulfate also makes th

32、e algaes cells work very slowly, and not much hydrogen is produced. Still, the researchers see this as a first step in their goal to produce hydrogen efficiently from algae. With more work, they may be able to speed the cells activity and produce larger quantities of hydrogen.只可惜消除硫酸盐不仅使藻类细胞的工作速度减慢，

33、而且大大减少了氢的数量。尽管如此，研究人员认为，对于实现有效率的利用藻类产生氢这一目标，他们已经迈出了第一步。随着工作量的加大，他们可以加速细胞的活动，从而产生大量的氢气。The researchers hope that algae will one day be an easy-to-use fuel source. The organisms are cheap to get and to feed, Ghirardi says, and they can grow almost anywhere: You can grow them in a reactor, in a pond. Y

34、ou can grow them in the ocean. Theres a lot of flexibility in how you can use these organisms. 研究人员们希望，总有一天藻类会成为很容易使用的燃料来源。藻类这种生物极易存活，他们可以在几乎任何地方成长。奇若蒂说，：“你可以将它放在一反应堆或是池塘里，也可以在海洋中找到它们，人们可以灵活的使用藻类的用途广泛。”词汇:panel n. 嵌板，发热板，仪器板 miniature adj. 口巧.微型的carbon dioxide 二氧化碳 algae n. 水藻，海藻starch n. 淀粉 sulfate

35、 n. 硫酸盐，硫酸酯photosynthesis n. 光合作用注释:1. convert., into. : 将转换为2. Colo. : Colorado，(美国科罗拉多州)的缩写形式3. Green algae: 绿藻4.trick them into producing hydrogen: 想方设法使它们产生氢。trick作为动词，有“欺骗、哄骗”的意思，但是在这里的意思是“设法”或“采取措施”。练习：1. What does the writer say about plants concerning solar energy?A) Plants are the real expe

36、rts in producing solar energy.B) Plants have been used to produce solar energy.C) Plants have been using solar energy for billions of years.D) Plants have been a source of solar energy.2. Why do some scientists study how plants convert sunlight carbon dioxide, and water into sugars and starches?A) B

37、ecause they want algae to produce sugars and starches.B) Because they want green plants to become a new source of energy.C) Because they want to turn plant sugars to a new form of energy.D) Because they want to make photosynthesis more efficient.3. According to the fifth paragraph, under what condit

38、ions are algae able to use solar energy to make hydrogen?A) When there is a lot of oxygen in the air.B) When there is no oxygen in the air.C) When photosynthesis is taking place.D) When enough starch is stored.4. Researchers have met with difficulties when trying to make algae produce hydrogen effic

39、iently. Which one of the following is one such difficulty?A) It is not possible to remove sulfate from the environment.B) It is not possible to work in an airfree environment to produce hydrogen.C) It is not easy to make sugars instead of hydrogen.D) It is too slow for algae to produce hydrogen when

40、 the sulfate is removed.5. What is NOT true of algae?A) They are easy to grow.B) They can be a very good fuel source.C) They are cheap to eat.D) They can be used in many ways.答案与题解：1.C 根据文章第一段最后一句的意思，c是正确选择：植物从来就利用阳光作为能源。2.B文章的第三段说，科学家企图将植物或植物类生物细胞作为微型光合能源供应站来研究，并举例说，他们正在用绿藻进行实验，若成功，绿藻所产生的氢将可用来为汽车的燃

41、料电池充电。所以答案是B。3.B 文章第四段告诉我们：algae will produce hydrogen in an air free environment.没有空气的情况肯定就没有氧气了。该段最后一句又说，是氧阻止绿藻制造氢。4.D选项A、B都不是正确答案，因为短文的第六段告诉我们，remove sulfate和work in an air free environment都是可能的，但问题是两者都有弊端，使氢的制造不那么容易。D所述内容就是困难之一：绿藻细胞因为没有了sulfate而减缓工作速度，因此产生不了多少氢。5.C 根据短文最后一段的描述，绿藻可以在任何地方生长，它们是很容易

42、使用的燃料能源，而且用途广泛，所以，A、B、C都是正确的描述，不是答案。C是答案，因为“The organisms are cheap to get and to feed”中的feed是“养殖”的意思，不能解释为“吃”。返回+第三十六篇 Listening Device Provides Landslide Early Warning（听觉仪器提供早期山崩预警）A device that provides early warning of a landslide by monitoring vibrations in soil is being tested by UK researcher

43、s. The device could save thousands of lives each year by warning when an area should be evacuated, the scientists say. Such natural disasters are common in countries that experience sudden, heavy rainfall, and can also be triggered by earthquakes and even water erosion.英国研究者们正在测试一种仪器，它可以通过监测土壤振动提供早期

44、山崩预告。科学家们说，这种仪器通过警报某处有险情需要撤离，每年可以拯救成千上万的生命。经历过骤降大雨，地震甚至土壤侵蚀的国家，山崩这样的自然灾害是很常见的。Landslides start when a few particles of soil or rock within a slope start to move, but the early stages can be hard to spot. Following this initial movement, slopes can become unstable in a matter of hours or minutes, say

45、s Nell Dixon at Southborough University1, UK. He says a warning system that monitors this movement might be enough to evacuate a block of flats or clear a road, and save lives. 当同一个山坡上的一些土壤或石块开始移动时，山崩就开始了，但早期很难发现。接着这个初始运动，“山坡在数分钟或数小时内变得不稳定，”英国拉夫堡大学尼尔迪克森说。他说，一个监控这种运动的警报系统“足以疏散一个街区的人或清出一条马路，拯救生命”。The

46、most common way to monitor a slope for signs of an imminent landslide is to watch for changes in its shape. Surveyors can do this by measuring aside directly, or sensors sunk into boreholes or fixed above ground can be used to monitor the shape of a slope. Slopes can. however, change shape without t

47、riggering a landslide, so either method is prone to causing false alarms. Now Dixons team has developed a device that listens for the vibrations caused when particles begin moving within a slope.监视迫近的山崩，最常见的办法就是观察这座山形状的变化。研究者们可以直接测量，也可以在钻孔中或者地表面上探测山坡形状的变化。可是，山坡改变形状也未必就导致山崩。所以任何一种方法都可能导致误警。现在，迪克森的团队已

48、发明了一种仪器，它在一个山坡内的颗粒开始移动时可以接收到振动。The device takes the form of a steel pipe dropped into a borehole in a slope. The borehole is filled in with gravel around the pipe to help transmit high-frequency vibrations generated by particles within the slope. These vibrations pass up the tube and are picked up by a sensor on the surface. Software analyses the vibration signal to determine whether a landslide may be imminent.这个仪器是钢管形状，探人山坡上的一个钻孔中。钻孔中仪器的四周填满沙砾，有助于传导山坡内颗粒产生的高频振动波。
