2、, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “Im an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”On the station, the ordinary becomes strange. The exerci

You can end up with what astronauts call a carbon-dioxide headache.Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before

5、you float out of your seat,”Your inner ear thinks yourre falling . Meanwhile your eyes are telling you youre standing straight. That can be annoyingthats why some people feel sick.” Within a couple days truly terrible days for some astronauts brains learn to ignore the panicky signals from the inner

These animals typically live between the surface of the ocean and a depth of

16、 about 3,300 feetas far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless theyre eating it, or unless something is eating them.

17、” And they are as clear as glass. How does an animal become see-through? Its trickier than you might think. The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its origin

18、al path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily. But a transparent object doesnt absorb or scatter light, at least not very much, Light can pass through it without bendin

19、g or stopping. That means a transparent object doesnt look very different from the surrounding air or water. You dont see it -you see the things behind it. To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain

20、 pigments(色素) that absorb specific colors of light. But a transparent animal doesnt have pigments, so its tissues wont absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.Animals are built of many different materials-skin,

21、fat, and more-and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, i

22、t is easier to be seethrough. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does

23、. They need to look uniform. But how theyre doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.63. According to Paragraph 1, transparent animals_. A. stay in groups B. can be easily

24、damaged C. appear only in deep ocean D. are beautiful creatures64. The underlined word “dead” in Paragraph 3 means_. A. silently B. gradually C. regularly D. completely65. One way for an animal to become transparent is to _. A. change the direction of light travel B. gather materials to scatter ligh

25、t. C. avoid the absorption of light D. grow bigger to stop light.66. The last paragraph tells us that larger transparent animals_. A. move more slowly in deep water B. stay see-through even after death C. produce more tissues for their survival D. take effective action to reduce light spreading【解析】试

26、题分析：文章解释了生活在海洋的透明生物的特点，透明原理，以及形成机制。63.B 细节理解题。文章第一段第三行：Mostof them are extremely delicate and can be damaged by a simple touch。得知B选项：透明动物是很容易受伤的。故选B。64.D 词义猜测题。该词出现在文章第三段第三行。前文提到了：你能看到的物体一种是对光线进行了散射；而另外一种是对光线的吸收。既然吸收了，那在光的传播过程中就完全阻止了，因此这里dead是完全的意思。故选D。65.C 推理判断题。根据第五段第一句To become transparent, an an

27、imal needs to keep its body from absorbing or scattering light。可知，想变透明就要避免散射或吸收光线，因此其中的一个方法是C选项，避免光线的吸收。故选C。66.D 推理判断题。根据最后一段第一句中的make all the different tissues in their bodies slow down light exactly as much as water does可以推断出D为正确答案。其中slowdown对应reduce。故选D。【考点定位】科技类说明文【名师点睛】做科技类说明文时，考生应能：理解语篇主旨要义，理解

Cell-phones are part of a growing mountain of electronic waste like com

29、puters and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals

30、 was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed,

31、the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finish

32、ed products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.The U.S. Environmental Protection Agency notes that most waste is dangero

33、us in that “the production, distribution, and use of products as well as management of the resulting waste all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start for instance, buying reusable products and recycling.In many countries the c

34、oncept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?Governments incentive to require produ

35、cers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?From the governments point of view, a primary goal of laws requiring extended producer

36、 responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.58.By mentioning the Swiss study, the author intends to tell us that _ .A. the weight of e-goods is rather smallB. E-waste deserves to be made go

Its very l

40、ikely that youll want to have volunteers to help with the organizations activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.Lets begin with the question of why people volunteer. Researchers have identified several factors t

41、hat motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select voluntee

42、rs, you may need to understand the motivations of the people you wish to attract.People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift peoples wish of partic

43、ipation from an internal factor (e.g., “I volunteer because its important to me”) to an external factor (e.g., “I volunteer because Im required to do so”). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer a

44、ctivities a must.Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the

45、most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training metho

46、ds that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social

47、role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in Hospital is an

48、 important part of who I am.” Consistent with the researchers expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: “Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity. Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity”.61.People volunteer m
