6、replacedD.fixed二、第二部分：阅读判断(总题数：1，分数：7.00)So Many Earths The Milky Way (银河) contains billions of Earth-sized planets that could support life thats the finding of a new study. It draws on date that came from NASAs top planet-hunting telescope. A mechanical failure recently put that Kepler space telesc

7、ope out of service. Kepler had played a big role in creating a census of planets orbiting some 170, 000 stars. Its data have been helping astronomers predict how common planets are in our galaxy. The telescope focused on hunting planets that might have conditions similar to those on Earth. The autho

8、rs of a study, published in The Proceedings of the National Academy of sciences, conclude that between 14 and 30 out of every 100 stars, with a mass and temperature similar to the Sun, may host a planet that could support life as we know it. Such a planet would have a diameter at least as large as E

9、arths, but no more than twice that big . The planet also would have to orbit in a stars habitable zone. Thats where the surface temperature would allow any water to exist as a liquid. The new estimate of how many planets might fit these conditions comes from studying more than 42, 000 stars and iden

10、tifying suitable worlds orbiting them. The scientists used those numbers to extrapolate (推算) to the rest of the stars that the telescope could not see . The estimate is rough, the authors admit. If applied to the solar system, it would define as habitable a zone starting as close to the Sun as Venus

11、 and running to as far away as Mars. Neither planet is Earthlike (although either might have been in the distant past). Using tighter limits, the researchers estimate that between 4 and 8 out of every 100 Sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400 days t

12、o complete a yearly orbit. Four out of every 100 sunlike stars doesnt sound like a big number. It would mean, however, that the Milky Way could host more than a billion Earth-sized planets with a change for life. （分数：7.00）(1).The Kepler space telescope has been in service for 15 years. （分数：1.00）A.Ri

Pittsburghs many hills arent kind to bikers. Anyone hoping to pedal to wo

16、rk there has to contend with steep streets like Canton Avenue, which famously climbs at a nearly 40-degree angle. As a result, some residents avoid biking altogether. 2. But University of Pittsburgh graduate Micah Toll, 23, and a few friends recently launched an invention that they hope will increas

17、e the citys pedal power. An electric bike called to Pulse PEVO. A super-strong battery powers the bicycle. Able to hit nearly 20 miles per hours without pedaling, it zips battery powers the bicycle. Able to hit nearly 20 miles per hour without pedaling , it zips up the citys most daunting(令人却步的)hill

24、n .第二篇 The Magic of Sound Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function: it not only moves people but also can shock people. Our eardrums can withstand sound within 20 to 80 decibels(分贝). Once sound exceeds this limit

25、, even beautiful music will become ear-splitting noise and harm health.A strong blast(响声) of high sound can twist and break a solid iron sheet. High sound of 150 decibels can kill a healthy rat. In movies, sometimes the hero can produce a sound that ordinary people cant hear and only those who have

26、the same ability can feel.In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20000Hz is called ultrasonic(超音波的). Dolphins, whales and bats can make such high-frequency sound. It does no harm to health. Sound less than 20Hz is called infrasonic(次声)waves.

27、 When we move, the air will vibrate. The vibration of air can produce infrasonic wave.As the frequency of infrasonic waves is close to that of peoples internal organs, infrasonic wave may cause resonance(共振) in human bodies. As a result, peoples vision may weaken and internal organs may rupture(断裂).

28、 However, whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low, it wont damage internal organs or a persons health. If the intensity of infrasonic wave exceeds 160 decibels, it is extremely harmful. When wind blows at a force of 3 or 4 over the se

29、a, it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power. （分数：15.00）(1).What could be the best

30、 title of the passage? （分数：3.00）A.The power of musicB.The harms of noisesC.The magic of soundD.The discovery of infrasonic waves(2).What does the author say about music? （分数：3.00）A.It may be harmful to peoples healthB.It always cheers people upC.It is very often difficult to understandD.It sounds be

31、tter when it is loud enough(3).It is true that the sound （分数：3.00）A.of nature is the most beautifulB.over 80 decibels is harmful to peopleC.of high intensity benefits animalsD.in movies is pleasing to the ear(4).An ultrasonic sound （分数：3.00）A.is very loudB.does harm to peoples healthC.cannot be hear

32、d by peopleD.is produced by the hero in movies(5).It can be found from the last paragraph that infrasonic waves （分数：3.00）A.are harmless to peoples healthB.exist in peoples internal organsC.can be used as deadly weaponsD.can improve eyesight第三篇 Compact Disks If someone says to you your music CDs dont

33、 really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he is right in that sound is actually recorded onto the CDs as special numbers a digital code. The code is pressed onto the CD as bumps(隆起) on a long spiral track almost five kilometers long

34、. These bumps are an average of 0.5 microns(微米) wide. A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player turn the reflected light back into the original code. This means you can he

35、ar the original code as music. Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes(探测仪) communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phon

36、es need digital codes. Weather radios also tune into specific signals using these codes. There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk. Another format is the CD-ROM. The technology for re

37、cording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc Read Only Memory. This disk is like a “super“ floppy disk that can hold lots of information. One

38、CD-ROM can hold the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs. CDs were first sold to the public in 1982 These CDs still play well and sound fine. Current CDs are expected to last between 70 to

39、 200 years. Of course, you can make sure your CDs last a long time by taking care of them. Science keeps on developing. It may not be many more years before a completely new technology is invented and introduced to the public for music recording. In the meantime, there is no doubt you will continue

40、to enjoy listening to your favorite music on CDs and playing your favorite computer games on CD-ROMs. （分数：15.00）(1).Music is recorded onto CDs as （分数：3.00）A.laser beamsB.digital codesC.musical notesD.special sounds(2).E-mail is mentioned in the third paragraph to show （分数：3.00）A.the variety of digit

41、al communicationsB.the development of new technologiesC.the usefulness of digital codesD.the relationship between communication and technology(3).One of the differences between CD-RWs and CD-ROMs is （分数：3.00）A.CD-ROMs can be used for longer timeB.CD-ROMs cannot be rewritten onC.CD-RWs hold more info

42、rmationD.CD-RWs are merely used for music recording(4).CDs can last a long time if （分数：3.00）A.they are seldom usedB.they play well and sound fineC.their users take good care of themD.they are developed with new technology(5).It can be inferred from the passage that （分数：3.00）A.CD-ROMs are more expens

43、ive than other CDsB.new technology for music recording is being developedC.the author likes listening to musicD.floppy disks are no longer in use五、第五部分：补全短文(总题数：1，分数：10.00)Do You Have a Sense of Humor? Humor and laughter are good for us. There is increasing evidence that they can heal us physically,

44、 mentally, emotionally, and spiritually. In fact, every system of the body responds to laughter in some positive, healing way. So how can we get more laughter into our lives? (46) Psychologist and author, Steve Wlison, has some answers. Many people believe that we are born with a sense of humor.They

45、 think, “either youve got it, or you dont“ Dr.Wilson points out that this false. (47) The parts of brain and central nervous system that control laughing and smiling are mature at birth. (48) (After all, when a baby laughs, we dont rush over and say, “That kid has a great sense of humor!“)A sense of

46、 humor is something that you can develop over a lifetime. Sometimes people think that they dont have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to express humor. (49)Then we will make others laugh, too. A person who h

47、as a true sense of humor is willing and able to see the funny side of everyday life.One of the best definition of a sense of humor is“the ability to see the nonserious element in a situation.“Consider this sign from a sore window.“ Any faulty merchandise will be cheerfully replaced with merchandise

48、of equal quality.“ The store manager probably placed the sign in the window to impress customers with the stores excellent service. (50)As Dr.Wilson says, “a good sense of humor means that you dont have to be funny; you just have to see whats funny.“ A. He advises us to lose our inhibitions(抑制) and

49、try to laugh at ourselves. B. Is it possible to develop a sense of humor? C. However, that does not mean that infants have a sense of humor. D. What is true, however, it that we are born with the capacity to laugh and smile E. Everyone experiences this emotion F He had a serious purpose, but if you have a sense of humor, you will probably find the sign funny! （分数：10.00）A.B.C.D.E.F.A.B.C.D.E.F.A.B.C.D.E.F.A.B.C.D.E.F.A.B.C.D.E.F.六、第六部分：完形填空(总题数：1，分数：15.00)Citizen Scientists Understanding how nature responds to climate change wi
