6、ws on data that came from NASAs top planet-hunting telescope.A mechanical failure recently put that Kepter space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars. Its date have been helping astronomers predict how common planets are in

7、 our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors 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

8、host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earths but no more than twice that big.The planet also would have to orbit in a stors habitable zone. Thats where the surface temperature would allow any water to exist as liquid.The new esti

9、mate of how many plantes might fit these conditions comes from studying more that 42,000 stars and identifying 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 appl

10、ied to the solar system，it would define as habitable a zone starting as close ot the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike(although either might have been in the distant pase). Using tighter limits the researchers estimate the between 4 and 8 out of every 100 s

11、unlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to 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 chance for lif

Anyone hoping to pedal

15、 to work there has to contend with steep streets like Canton Avenue，which famously climabs 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

16、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 pedating ，it zips up the citys most daunting(令人却步的)hills.

17、Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.3 If it sounds like Toll has a knack(窍门) for fixing problems，thats because he does. In high school，he designed a new type of construction beam. It weights no more than a feather pillow but can be u

18、sed to build sturdy(坚固的)homes for refugees fleeing war or natural disaster.For his work，Toll was invited to attend the Inter International Science and Engineering Fair(Isef)twice，in 2006 and 2007. The annual competition for young researchers is program of Society for Science&the Public(thats the par

19、ent organization of Science News for Kids).Toll says that when it comes to science，he keeps it simple：“You see a problem and say，“How could I solve that?”4 Hes not the only to take that approach.

23、 benefit their community答案：EDBC EBCF第4部分，阅读理解Approaches to Understanding IntelligencesIt bays to be smart, but we are not all smart in the same way .You may be a talented musician, but you might not be a good reader. Each of us is different.Psychologists disagree about what is intelligence and what

24、are talents or personal abilities .Psychologists have two different views on intelligence .Some believe there is one general intelligence .Others believe there are many different intelligences .Some psychologists say there is one type of intelligence that can be measured with IQ tests .These psychol

25、ogists support their view with research that concludes that people who do well on one kind of test for mental ability do well on other tests .They do well on tests using words, numbers or pictures. They do well on individual or group tests, and written or oral tests .Those who do poorly on one test,

26、 do the same on all tests.Studies of the brain show that there is a biological basis for general intelligence .The brain of intelligence people use less energy during problem solving .The brain waves of people with higher intelligence show a quicker reaction .Some researchers conclude that differenc

27、es in intelligence result from differences in the speed and effectiveness of information processing by the brain .Howard Gardner, a psychologist at the Harvard School of Education, has four children .He believes that all children are different and shouldnt be tested by one intelligence test .Althoug

28、h Gardner believes general intelligence exists, he doesnt think it tells much about the talents of a person outside of formal schooling .He think that the human mind has different intelligences .These intelligences allow us to solve the kinds of problems we are presented with in life .Each of us has

29、 different abilities within these intelligences .Gardner believes that the purpose of school should be to encourage development of all of our intelligences .Gardner says that his theory is based on biology .For example ,when one part of the Brain is injured ,other parts of the brain still work .Peop

30、le who cannot talk because of Brain damage can still sing .So ,there is not just one intelligence to lose .Gardner has Identified 8 different kinds of intelligence; linguistic, mathematical, spatial, musical, Interpersonal, intrapersonal, body-kinesthetic(身体动觉的),and naturalistic .31. What is the mai

31、n idea of this passage?A. How to understand intelligence.B. The importance of intelligence.C. The development of intelligence tests.D. How to become intelligent.32. Which of the following statements is true concerning general intelligence?A. Most intelligent people do well on some intelligence tests

32、.B. People doing well on one type of intelligence test do well on other tests.C. Intelligent people do not do well on group tests.D. Intelligent people do better on written tests than on oral tests.33. Gardner believes that _.A. children have different intelligences.B. all children are alike.C. chil

33、dren should take one intelligence test.D. there is no general intelligence.34. According to Gardner, schools should _.A. test students IQs.B. train students who do poorly on tests.C. focus on finding the most intelligent students.D. promote development of all intelligences.35. Gardner thinks that hi

34、s theory has a _ .A. musical foundation.B. biological foundation.C. intrapersonal foundation.D. linguistic foundation.答案：ABADBMusic is one of the most beautiful forms of artistic expression是ever invented. In movies and plays，music has an added function：it not only moves people but also can shock peo

35、ple.Our eardrums can withstand sound within 20 to 80 decibels(分贝).Once sound exceeds this limit，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，som

36、etimes the hero can produce a sound that ordinary people cant hear and only those who have 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-frequenc

37、y sound.It does no harm to health.Sound less than 20Hz is called infrasonic(次声)waves. 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

38、bodies. As a result，peoples vision may weaken and internal organs may rupture(断裂). 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 inf让sonic wave exceeds 160 deci

39、bels，it is extremely harmful. When wind blows at a force of 3 or 4 over the sea，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 scient

40、ific tools and powerful electric power.36 What could be the best title of the passage?A The power of musicB The harms of noisesC The magic of soundD The discovery of infrasonic waves37 What does the author say about music?A It may be harmful to peoples halthB It always cheers people upC It is very o

42、ealthC cannot be heard by peopleD is produced by the hero in movies40 It can be found from the last paragraph that infrasonic wavesA are harmless to peoples healthB exist in peoples internal organsC can be used as deadly weaponsD can improve eyesight答案：CABCCCompact DisksIf someone says to you your m

43、usic CDs dont 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.1 The code is pressed onto the CD as bumps on a long spiral track almost five kilom

44、eters long. These bumps are an average of 0.5 microns 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 player2 turn the reflected light back into the original code. This means you

45、can hear the original code as music.Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes 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

46、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 disk3. Another format is the CD-ROM. The technology for re

47、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 Memory4. This disk is like a super floppy disk that can hold lots of information. One 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
