Similar to your bedside alarm clock， your internal clock2 runs on a 24-

5、hour cycle. This cycle，called a circadian rhythm，helps control whenyou wake，when you eat and when you sleep.Somewhere around puberty，something happens in the timing of the biological clock. Theclock pushes forward，so adolescents and teenagers are unable to fall asleep as early as they used to. When

6、your mother tells you its time for bed，your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.This shift4 is natural for teenagers. But staying up very late and sleeping late can get your bodys

7、clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems，too. Teenagers are put in a kind of a gray cloud6 when they dont get enough sleep，says Mary Carskadon，a sleep researcher at Brown University in Providence，RI7 .

8、It affects their mood and their ability to think and learn.But just like your alarm clock，your internal clock can be reset. In fact，it automatically resetsitself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of n

9、ight play important roles in setting our internal clocks. For years，researchers thought that the signals that synchronize the bodys clock8 were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensing systems. One system allow

10、s us to see. The second system tells our body whether its day or night.詞匯：circadian/s3:keidin/ adj. 晝夜節(jié)奏的，生理節(jié)奏的adolescent/dulesnt/ n青少年；adj青少年的puberty/ pju:bti/ n發(fā)育；青春期sync/sik/ n. （口語(yǔ)）同步；和諧，協(xié)調(diào)synchronize/sikrnaiz / V.（使）同時(shí)發(fā)生；（使）同步注釋：1.make light of ：輕視，不在乎。例如： We should not make light of their achi

What is implied in the second paragraph?A Young childrens biological clock ha

14、s the same rhythm with that of the teenagers.B People after puberty begin to go to bed earlier due to the change of the biological clock.C Children before puberty tend to fall asleep earlier at night than adolescents.D Teenagers go to bed later than they used to due to the light from the computer sc

15、reen.3. In the third paragraph the author wants to tell the reader thatA it is natural for teenagers to stay up late and get up late.B staying up late has a bad effect on teenagers ability to think and learn.C during puberty most teenagers experience a kind of gray cloud.D it is hard for teenagers t

16、o get out of bed in the morning.4. Which of the following statements is NOT true according to the fourth and fifth paragraphs?A Our biological clock resets itself automatically.B light gets through our eyes and resets our biological clock.C Our internal clock as well as the alarm clock can be reset

17、automatically.D Our internal clock，like the alarm clock，can be reset.5. According to the last two paragraphs， what did the previous researchers think about the human eyes light-sensing system?A The human eye had two light-sensing systems.B The human eye had one light-sensing system.C The human eye c

18、ould sense the light of day more quickly than the dark of night.D The human eye could reset our internal clocks in accordance with the alarm clocks.答案與題解：1.B 第一段第二句提供了答案。句中的your internal clock 即指a clock located inside ourBrains。2. C 第二段主要內(nèi)容是告訴讀者，過了青春期（puberty），由于生物鐘節(jié)奏的變化，青少年（adolescents and teenager

19、s）比以前要晚睡幾小時(shí)。所以C是該段所隱含的內(nèi)容。3. B 第三段的最后一句直接給出了答案。4. C 根據(jù)第四和第五段的內(nèi)容，鬧鐘和生物鐘都可以重新設(shè)定時(shí)間，但生物鐘能通過眼睛接受的日光來(lái)自動(dòng)調(diào)節(jié)生理節(jié)奏。所以A、B和D都是這兩段中所述內(nèi)容，C是正確選擇，因?yàn)轸[鐘不能自動(dòng)重新設(shè)定時(shí)間。5.B 問題使用的是過去時(shí)，問的是研究者在最新發(fā)現(xiàn)（recent discoveries）之前對(duì)眼睛感光系統(tǒng)的認(rèn)識(shí)，即，the signals that synchronize the bodys clock were handled through the samepathways that we use to

20、 see （眼睛所接受到的平衡生物鐘的光信號(hào)同樣作用于人類的視覺系統(tǒng)），也就是說(shuō)，研究者之前認(rèn)為人類的眼睛只有一個(gè)感光系統(tǒng)。但最新發(fā)現(xiàn)卻是，人的眼睛有兩個(gè)感光系統(tǒng)。第十九篇Graphenes Superstrength1Big technology comes in tiny packages. New cell phones and personal computers get smallerevery year，which means these electronics require even smaller components on the inside.Engineers are

21、looking for creative ways to build these components，and theyve turned their eyes to graphene，a superthin2 material，made of carbon，that could change the future of electronics.This years Nobel Prize for Physics3 has been awarded to Andre Geim and Kostya Novoselovfrom the University of Manchester4，UK.

22、for the discovery of graphene. Graphene isnt just small,its“the thinnest possible material in this world，” says Novoselov. He calls it a“wondermaterial. ”Its so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper. If you were to hold

23、a sheet of graphene in your fingers5，youd have no idea because you wouldnt be able to see it.Carbon is one of the most abundant elements in the universe. Every known kind of lifecontains carbon. Graphene is a sheet of carbon，but only one atom thick. You dont have to lookfar to find grapheme its all

24、around you.If you want this high-tech wonderstuff6，all you need is a pencil，paper and a little adhesivetape. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesivetape over the area7. When you pull up the tape，youll see that it pulls up a thin layer of some ofthe

25、 shading from your pencil. That layer is called graphite，one of the softest minerals in the world.Now stick the same piece of tape on another sheet of paper and pull the tape up there should be an even thinner layer，this time left on the paper. Now imagine that you do this over and over，until you ge

26、t the thinnest possible layer of material on the paper. This layer would be only one atom thick，and you wouldnt be able to see it. Graphite is made of layers of graphene，so when you get to the thinnest possible layer，youve found graphene.詞匯：graphene/ grfi:n/ n石墨烯abundant/bndnt / adj豐富的，充裕的atom/ tm/n

27、原子adhesive/ dhi:siv/ n膠粘劑； adj. 黏著的stack/stk/ v使成堆，堆放graphite / grfait / n石墨注釋：1. superstrength：超強(qiáng)的力量。該詞是一個(gè)合成詞，由兩部分組成， super（超級(jí)的）和strength （力量）。2. superthin：超薄。見注釋1。3.

29、B Creative ways.C Graphene.D Both A and B.2. According to the second and third paragraphs，what is true of graphene?A It can be used to make paper.B It is possible to see it with our naked eye.C It is easy to find graphene.D It is possibly the thickest material in the world.3. Which of the following

30、can be used to replace the word “apply”in paragraph 4?A request.B polish.C use.D put.4. Which of the following is NOT meant in the last two paragraphs?A Graphene is made of graphite，one of the softest materials in the world.B Graphite is made of layers of graphene，the thinnest material in the world.

31、C When we get to the thinnest possible layer of graphite，we find graphene.D With a pencil，a sheet of paper and a piece of adhesive tape，we can find graphene.5. Graphenes superstrength lies in the fact thatA It is the thinnest material in the world.B It is made of the most abundant elements in the wo

32、rld.C It can help to make electronic components smaller. D It helps engineers to produce more sensitive electronic products.答案與題解：1. C 第一段最后一句提供了答案：工程師將眼光投向石墨烯，一種由碳原子組成的超薄材料，這種材料能夠改變電子產(chǎn)品的未來(lái)。2.C 第二段倒數(shù)第二句告訴我們，25,000 層石墨烯才能堆砌成一張普通白紙的厚度，這是為了說(shuō)明石墨烯是多么的薄，而不是說(shuō)它可以用來(lái)造紙，所以A不是正確答案。第三段最后一句說(shuō)明石墨烯就在我們周圍，因此C是答案。B和D的

33、表述內(nèi)容都與該兩段內(nèi)容不符合。3.D apply. over：將涂（敷）在上。4.A 最后兩段告訴我們，用一張紙，一支鉛筆和一片膠帶就能找到石墨烯；無(wú)數(shù)層石墨烯構(gòu)成石墨，當(dāng)鉛筆留在紙上的石墨被膠帶剝離到最薄一層時(shí)，我們就得到了石墨烯。因此只有A不是最后兩段的表述內(nèi)容。5. C 第一段提供了答案。隨著電子產(chǎn)品越來(lái)越小，需要更小的電子組件（components) ，而石墨烯作為最薄的材料可以幫助工程師實(shí)現(xiàn)這一目標(biāo)。這就是石墨烯力量所在。*第三八篇 Life Form Found on Saturns TitanScientists say they have discovered hints of

34、 alien life1 on the Saturns moon2. The discovery of a sort of life was announced after researchers at the US space agency,NASA3,analyzed data from spacecraft Cassini4,which pointed to,the existence of methane-based form of life on Saturns biggest moon.Scientists have reportedly discovered clues show

This,they say,points to the existence of somebugs5 consuming the hydrogen at the surface of t

36、he moon less than half the size of the Earth.We suggested hydrogen consumption because its the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,says NASA scientist Chris McKay.If these signs do turn out to be a sign of life,it would be doubly exciting because it

37、 would represent a second form of life independent from water-based life on Earth.To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures a

38、re around 90 Kelvin6(minus 290 degrees Farenheit),a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titans surface and much too cold to support life as we know it.Scientists had expected the Suns in

39、teractions with chemicals in the atmosphere to produce a coating of acetylene on Titans surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titans surface can very well have a non-biological explanation,said Mark Allen,a principal investigator7 of the

40、 NASA Titan team.Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,Allen said. We have a lot of work to do to rule out8 possible non-biological explanations. It is more likely that a chemical process,without b

41、iology,can explain these results.詞匯：Saturn /stn/ n土星 methane/mi:ein/ n甲烷，沼氣Titan/taitn/ n土衛(wèi)六 acetylene/setili:n/ n乙炔alien/eiljn/ n外星人；adj外星球的；相異的 conservatism/kns:vtizm/ n保守主義,守舊注釋：1.hints of alien life：外星生命跡象。2.the Saturns moon：指土衛(wèi)六（Titan) 。土衛(wèi)六又稱泰坦星，是土星衛(wèi)星中最大的一顆。3.NASA：美國(guó)國(guó)家航空航天局的縮寫，全稱是： National Aer

Which of the following can replace the title of this passage?A Earthlike Living Beings Found on Titan.B Finding of One More Moon of Saturn

47、.C Titan,a New Satellite Found.D A different Life Form, a Possibility.答案與題解：1. C 短文的第一段提供了答案。該段告訴讀者，科學(xué)家在土星的衛(wèi)星土衛(wèi)六（ Titan ）上發(fā)現(xiàn)了生命的跡象，這些生命的存在是以甲烷為基礎(chǔ)的。2.A根據(jù)第二段“Scientists have reportedly discovered clues showing primitive alien beings arebreathing in Titans dense atmosphere filled with hydrogen.”，說(shuō)明土衛(wèi)六（

48、Titan）有生命跡象。因此A是答案。3. B this form of life 指的是土衛(wèi)六（ Titan ）上以甲烷為生命基礎(chǔ)呼吸氫氣的生物，即該文討論的主題。4.A科學(xué)家至今對(duì)土衛(wèi)六是否存在生物有不同的觀點(diǎn)和解釋。Allen 說(shuō)要做出土衛(wèi)六上有生物的結(jié)論，首先必須對(duì)Titan 上沒有生物的觀點(diǎn)做出回應(yīng)；要排除土衛(wèi)六上可能沒有生物的觀點(diǎn)，我們還須付出努力。所以只有A是正確選擇。5.D該短文的主題是，科學(xué)家在土衛(wèi)六（ Titan ）上發(fā)現(xiàn)了一種與地球生物不同的生命形式的跡象，即以甲烷為生命基礎(chǔ)呼吸氫氣的生物，但科學(xué)家還未能最后驗(yàn)證這一發(fā)現(xiàn)。第四段中的一個(gè)句子能夠揭示該短文的主題：“If t

50、ity of Chicagol1 Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills, then her female students are more likely to believe that boys are better than girls at math.

51、If these girls keep getting math-anxious female teachers2 in later grades, it may create a snowball effect on their math achievement3 said Levine. In other words,girls may end up learning math anxiety from their teachers4. The study suggests that if these girls grow up believing that boys are better

52、 at math than girls are,then these girls may not do as well as they would have ifthey were more confident.Just as students find certain subjects to be difficult, teachers can find certain subjects to bedifficult to learn - and teach. The subject of math can be particularly difficult for everyone.Res

53、earchers use the word anxiety to describe such feelings: anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math, that feeling can influencehow her female students feel about math. The study involved 65 girls,52 boys and 17 first- andsecond-grade teachers in ele

54、mentary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year, and the researchers compared the scores.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers

55、 turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math, such as when reading a sales receipt5. A teacher who got nervous looking at the numbers on a sales receipt, for example,was probably anxiou

56、s about math.Boys,on average,were unaffected by a teachers anxiety. On average,girls with math-anxiousteachers scored lower on the end-of-the-year math tests than other girls in the study did.Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math - and all of these girls had been taught by female teachers who had math anxiety.This is an interesting study,but the results need to be interpreted as preliminary and in needof replication with a larger sample6, said David Gea
