So Many ‘Earths’
The Milky Way(银河) contains billions of Earth-sized planets that could support life. That's the finding of a new study. It draws on data that came from NASA’s top planet-hunting telescope.
A mechanical failure recently put that Kepler space telescope 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 authors of a study, published in The Proceedings of the National Academy of sciences, conclude that between 14 and 30 0ut 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 Earth's, but no more than twice that big, The planet also would have to orbit in a star's habitable zone. That's 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 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. lf applied to the solar system, it would define as habitable a zone starting as close to the Sun as Venus 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 t0 400 days to complete a yearly orbit.
Four out of every 100 sunlike stars doesn’t 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 life.

16. The Kepter space telescope has been in service for 15 years.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】B

17. The main task of the Kepler space telescope is to find out planets with similar Conditions to Earth's.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】A

18. The planet that could support life might be a little bit smaller than Earth.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】B

19. The Earth is a planet orbiting in the Sun's habitable zone.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】A

20. The new finding is based on a thorough study of 170,000 stars in the Milky Way.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】B

21. The estimate of the number of planets that could support life is not very accurate.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】A

22. This is the first research finding about the planets with a chance for life.
    A. Right        B. Wrong        C. Not mentioned
【正确答案】C

Climate Change: The Long Reach

1     Earth is warming. Sea levels are rising. There's more carbon in the air, and Arctic ice is melting faster than at any time in recorded history. Scientist who study the environment to better gauge (评估) Earth's future climate now argue that these changes may not reverse for a very long time.
2     People burn fossil fuels like coal and oil for energy. That burning releases carbon dioxide, a colorless gas. In the air, this gas traps heat at Earth’s surface. And the more carbon dioxide released, the more the planet warms. If current consumption of fossil fuels doesn't slow, the long term climate impacts could last thousands of years – and be more severe than scientists had been expecting. Climatologist Richard Zeebe of the University of Hawaii at Manoa offers this conclusion in a new paper.
3    Most climate-change studies look at what's going to happen in the next century or so. During that time, changes in the planet’s environment could nudge(推动)global warming even higher. For example: Snow and ice reflect sunlight back into space. But as these melt, sunlight can now reach--and warm --the exposed ground. This extra heat raises the air temperature even more causing even more snow to melt. This type of rapid exaggeration of impacts is called a "fast feedback."
4    Zeebe says it's important to look at fast feedbacks. However', he adds, they're limited. From a climate change perspective, “This century is the most important time for the next few generations,” he told Science News. “But the world is not ending in 2100.” For his new study, Zeebe now focuses on “snow feedbacks.” while fast feedback events unfold over decades or centuries, slow feedbacks can take thousands of years. Melting of continental ice sheets and the migration of plant life---as they relocate to more comfortable areas -- are two examples of slow feedbacks.
5   Zeebe gathered information from previously published studies investigating how such processes played out over thousands of years during past dramatic changes in climate. Then he came up with a forecast for the future that accounts for both slow and fast feedback processes. Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius (8.1 degree Fahrenheit) change by the year 3000. But slow feedbacks added another l.50 C--for a 60 total increase, Zeebe reports. He also found that slow feedback events will cause global warming to persist for thousands of years after people run out of fossil fuels to burn.


A. A prediction of future climate change
B. Impact of burning fossil fuels
C. Fast feedbacks
D. Unpredictability of feedback processes
E. Rising of sea levels
F. Slow feedbacks

下面有3篇短文,每篇短文后有5道题。请根据短文内容,为每题确定1个最佳选项。

第一篇
The Mir Space Station

The Russian Mir Space Station, which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight, is remembered for its accomplishments in the human space flight history. It can be credited with many firsts in space.
The Soviet Union launched Mir, which was designed to last from three to five years, on February 20, 1986, and housed 104 astronauts over 12 years and seven months, most of whom were not Russian. In fact, it became the first international space station by playing host to1 62 people from 11 countries. From 1995 through 1998, seven astronauts from the United States took turns living on Mir for up to six months each2. They were among the 37 Americans who visited the station during nine stopovers by space shuttles.
The more than 400 million the United States provided Russian for the visits not only kept Mir operating, but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.
A debate continues over Mir’s contributions to science. During its existence, Mir was the laboratory for 23,000 experiments and carried scientific equipment, estimated to be worth $80 million, from many nations.3 Experiments on Mir are credited with a range of findings, from the first solid measurement of the ration of heavy helium(氦) atoms in space to how to grow wheat in space. But for those favouring human space exploration, Mir showed that people could live and work in space long enough for a trip to Mars. The longest single stay in space is the 437.7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995. And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station. The longest American stay was that of Shannon Lucid, who spent 188 days aboard Mir in 1996.
Despite the many firsts Mir accomplished, 1997 was a bad year out of 15 for Mir. In 1997, an oxygen generator caught fire. Later, the main computer system broke down, causing the station to drift several times and there were power failures.
Mir’s setbacks are nothing, though, when we compare them with its accomplishments. Mir was a tremendous success, which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible. But it’s time to move on to the next generation. The International Space Station being built will be better, but it owes a great debt to Mir.

31. We can learn from the passage that the Mir space station
A. was designed to last over 5 years
B. was built by Russians
C. played host to 7 astronauts from different countries
D. was visited only by Americans
【正确答案】B

32.one of the contributions Mir makes to science is that it
A. helps astronauts get close to Mars
B. enables scientists to develop new scientific equipment
C. sets a record of the longest single human stay in space
D. shows that multinational operations in space are less expensive
【正确答案】C

33. What happen to Mir in 1997?
A. It ran out of its fund
B. It was completely damaged by fire
C. Its main computer system broke down
D. Its reputation was ruined due to power failures
【正确答案】D

34. It can be inferred from the last paragraph that
A. space exploration will not experience setbacks
B. it is difficult for other space stations to exceed Mir’s success
C. Mir is the best long-term human habitation in space in history
D. multinational space operations are getting more accomplishments
【正确答案】D

35. what is the author’s attitude toward Mir?
A. Favorable
B. Indifferent
C. Ironic
D. Negative
【正确答案】A

Approaches to Understanding Intelligence

It pays 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 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 psychologists 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, 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 differences 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 shouldn’t be tested by one intelligence test .Although Gardner believes general intelligence exists, he doesn’t 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 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 .People 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.
36. What is the main 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.
【正确答案】A

37. Which of the following statements is true concerning general intelligence?
A. Most intelligent people do well on some intelligence tests.
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.
【正确答案】A

38. Gardner believe that
A. children have different intelligences
B. all children are alike
C. children should take one intelligence test
D. there is no general intelligence
【正确答案】A

39. According to Gardner schools should
A . promote development of all intelligences
B . test students’ IQs.
C . train students who do poorly on tests.
D . focus on finding the most intelligent students.
【正确答案】A

40. Gardner thinks that his theory has a
A . musical foundation.
B . intrapersonal foundation.

Eye tracker lets you drag and drop files with a glance
Bored of using a mouse? Soon you’ll be able to change stuff on your computer screen –
and then move it directly onto your smart phone or tablet (平板电脑) --with nothing more than a glance.
A system called EyeaDrop uses a head-mounted eye tracker that simulta1eously records your field of view so it kr10W8 where you are looking on the screen . Gazing at an object -- a photo, say -- and then pressing a key, selects that object. It can then be moved from the screen to a tablet' or smartphone just by glancing at the second device, as long as the two are connected wirelessly.
"The beauty of using gaze to support this is that our eyes naturally focus on content that we want to acquire," says Jayson Turner, who developed the system with colleagues at Lancaster University, UK.
Turner believes EyeDrop would be useful to transfer an interactive map or contact information from a public display to your Smartphone or for sharing photos.
A button needs to be used to select the object you are looking at otherwise you end up with the¨Midas touch"(点石成金) effect, whereby everything you look at gets selected by your gaze, says Turner. “Imagine if your mouse clicked on everything it pointed at,” he says.
Christian HoIz, a researcher in human-computer interaction at Yahoo Labs in Sunnyvale, California, says the system is a nice take on getting round this fundamental problem of using gaze-tracking to interact. “EyeDrop solves this in a slick (灵巧的) way by combining it with input o the touch devices we carry with us most of the time anyway and using touch input as a clutching mechanism, “he says. “This now allows users to seamlessly (无缝地) interact across devices far and close in a very natural manner.”
While current eye-trackers are rather bulky, mainstream consumer devices are not too far away. Swedish firm Tobii is developing gaze-tracking technology that can be installed in laptops and tablets and is expected to buy next year. And the Google Glass headset is expected to include eye-tracking in the future.
Turner says he has also looked at how content can be cut and pasted or drag-and-dropped using a mix of gaze and taps on a touch screen. The system was presented at the  Conference on Mobile and Ubiquitous Multimedia in Sweden, last week.

41. The eye-tracker technology enables us to
A. move an object from screen with a glance.
B. change our computer screen.
C. focus on anything that interests us.
D. get a smart phone connected wirelessly.
【正确答案】A

42. Why is a button needed?
A. To minimize the cost of Eye Drop
B. To choose as many objects as possible
C. To select what we want
D. To make Eye Drop different from others
【正确答案】B

43. The word “this” in paragraph 6 refers to
A. application of gaze-tracking in human-computer interaction.
B. interaction between human and computer.
C. generalization of Eye Drop system.
D. combination of gaze-tracking with input on touch devices.
【正确答案】D

44. which of the following statements is true of eye-trackers for consumer use?
A. they are costly.
B. they are available.
C. they are installed in Google Glass headset.
D. they are expected to come out soon.
【正确答案】D

45. what is Turner likely to study next?
A. how to present the system in public
B. how to get touch screen involved
C. how to cut and paste content from a public display
D. how to drag and drop with gaze and taps
【正确答案】D

The Day a Language Died

When Carios Westez died at the age of 76. A language died, too. Westez, more commonly known as Red Thunder Cloud, was the last speaker of the Native American language Catawba. Anyone who wants to hear the songs of the Catawba can contact the Smithsonian Institution in Washington, D.C., where, back in the 1940s, Red Thunder Cloud recorded a series of songs for future generations. ___________(46)They are all that is left of the Catawba language. The language that people used to speak is gone forever.
  We are all aware of the danger that modern industry can cause the world’s ecology(生态).However, few people are aware of the impact widely spoken languages have on other languages and ways of life. English has spread all over the world. Chinese, Spanish, Russian, and Hindi have become powerful languages as well. ___________(47)When this happens, hundreds of languages that are spoken by only a few die out.
Scholars believe there are around 6,000 languages around the world, but more than half of them could die out within the next 100 years. There are many examples, Araki is a native language of the island of Vanuatu, located in the Pacific Ocean. It is spoken by only a few older adults, so like Catawba, Araki will soon disappear. Many languages of Ethiopia will have the same fate because each one has only a few speakers. ___________(48)In the Americas, 100 languages, each of which has fewer than 300 speakers, are dying out.
Red Thunder Cloud was one of the first to recognize the danger of language death and to try to do something about it. He was not actually born into the Catawba tribe, and the language was not his mother tongue. ___________(49). The songs he sang for the Smithsonian Institution helped to make Native American music popular. Now he is gone, and the language is dead.
What does it mean for the rest of us when a language disappears? When a plant or insect or animal species dies, it is easy to understand what we’ve lost and to appreciate what this means for the balance of the natural word. However, language is only a product of the mind. To be the last remaining speaker of a language,like Red Thunder Cloud,must be a peculiarly lonely destiny, almost as strange and terrible as being the last surviving member of a dying species. ___________(50)

A. As these languages become more powerful, their use as tools of business and culture increases
B. However, he was a frequent visitor to the Catawba reservation in South Carolina, where he learned
the language.
C. Papua New Guinea is an extremely rich source of different language,but more than 100 of them are
in danger of extinction(灭绝).
D. For the rest of us, when a language dies, we lose the possibility of a unique way of seeing and
describing the world.
E. Some people might even try to learn some of these songs by heart.
F. These languages don’t have many native speakers.

地下煤引发即将来临的灾难
科学家们警告说,中国、印度和印尼的地下煤矿着火将严重威胁自然环境和人身安全。在丹佛举行的美国科学促进协会的会议上,一个专家小组的科学家们表示,林规模地地下大火将会提高地面温度,烧死周围的植物,由此产生的气体将会导致温室效应,甚至有可能引起森林大火。他们还警告说,大火释放出来的砷、汞等有毒物质还会污染当地的水源和土壤。
美国东佐治亚大学Swainboro分校的副教授Glenn Stracher说:“煤矿失火是一个全球性的灾难。”但令人惊奇的是很少有人知道这一点。
煤能够自己提高温度,存在充足的氧气时,它能够自然。它产生的热量并不会消失,在合适的阳光和氧气条件下,它就会自燃。这种情况可能发生在地下煤矿的煤堆,废弃的煤矿,甚至在煤的运输过程中。Stracher教授告诉与会代表们,每年在中国,这种情况会消耗掉2亿吨的煤。相比之下,美国每年的用煤量为十亿吨。Stracher教授关于由煤引起的大火的影响的分析已经在《国际煤生态学期刊》上发表。煤一旦燃烧起来,就可能燃烧几十年,甚至几百年。在这个过程中,会排出大量的温室气体、有毒气体和物质到大气中。
专家们讨论了这些大火对全球和地区气候变化的影响,一致认为火灾地点发生在地下,使得火灾不容易被发现。小组的一个成员,来自荷兰国际地质信息科学和地球观测研究院的Paul Van Dijk副教授已经同中国政府合作探测和控制中国北部地区的煤矿失火情况。
远程感应以及其他技术最终将能够允许科学家们估计出究竟这些大火释放出多少一氧化碳。Goodson工程公司的Gary Colaizzi提出了一种控制火势的方法。他们公司已开发出一种隔热水泥浆(一种稀灰浆用来填充裂缝),它可以被灌注到失火的煤矿中以切断氧气来源。
