It draws on date that came from NASAs topplanet-hunting telescope.A mechanical failure recently put that Kepler space t

6、elescope out of service. Keplerhad played a big role in creating a census of planets orbiting some 170,000 stars. Its datahave been helping astronomers predict how common planets are in our galaxy. Thetelescope focused on hunting planets that might have conditions similar to those onEarth.The author

7、s of a study,published in The Proceedings of the National Academy ofsciences,conclude that between 14 and 30 out of every 100 stars, with a mass andtemperature 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 Earths,

8、 but no more than twicethat big . The planet also would have to orbit in a stars habitable zone. Thats where thesurface temperature would allow any water to exist as a liquid.The new estimate of how many planets might fit these conditions comes fromstudying more than 42,000 stars and identifying sui

9、table worlds orbiting them. The scientists used those numbers to extrapolate （推算） to the rest of the stars that thetelescope could not see .The estimate is rough, the authors admit. If applied to the solar system, it woulddefine as habitable a zone starting as close to the Sun as Venus and running t

10、o as faraway as Mars. Neither planet is Earthlike （although either might have been in the distantpast）. Using tighter limits, the researchers estimate that between 4 and 8 out of every 100Sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400days to complete a yearl

11、y 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 achange for life.16. The Kepler space telescope has been in service for 15 years.A. Right B. Wrong C. Not mentioned17. The mai

12、n task of the Kepler space telescope is to find out planets with similar conditions to Earths.18. The planet that could support life might be a little bit smaller than Earth.19. The Earth is planet orbiting in the Suns habitable zone.20. The new finding is based on a thorough study of 170,000 stars

13、in the Milky Way.21. The estimate of the number of planets that could support life is not very accurate.22. This is the first research finding about the planets with a chance for life.第三部分：概括大意与完成句子阅读下面这篇短文，短文后有2项测试，任务：（1）1-4题要求从所给的4个选项中为段每段选择1个正确的小标题;（2）第5-8题 要求从所给的5个选项中选择4个正确选项，分别完成每个句子。Climate Ch

14、ange : The Long Reach1 . Earth is warming. Sea levels are rising. There s more carbon in the air, and Arctic iceis melting faster than at any time in recorded history. Scientists who study the environment tobetter gauge （评估） .Earths future climate now argue that these changes may not reverse for a v

15、ery 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 Earths surface . And the more carbon dioxidereleased , the more the planet warms . If current consumption of fossil fuels doesnt slow

16、,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 whats going to happen in the next century

17、or so .During that time, changes in the planets environment could nudge（推动） global warmingeven 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 airtemperature even more, causing even

18、 more snow to melt. This type of rapid exaggerationof impacts is called a fast feedback.4. Zeebe says its 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 nextfew generations, he told Science New

19、s “But the world is not ending in 2100”. For his newstudy. Zeebe how focuses on “slow 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 comf

20、ortable areas - are two examples ofslow 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. Thenhe came up with a forecast for the future that accounts for both slow and

21、 fast feedback processes. Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius （8.1 degreeFahrenheit） change by the year 3000. But slow feedbacks added another 1.5 -for a 6 total increase, Zeebe reports. He also found that slow feedback events will cause global warming to pers

Soon youll be able

25、to change stuff on your computer screen and then move it directly onto your smartphone or tablet（平板电脑） with nothing more than a glance.A system called EyeDrop uses a head-mounted eye tracker that simultaneously records your field of view so it knows where you are looking on the screen. Gazing at an

26、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 tha

27、t 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 sel

28、ect 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 Holz, 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 on the touch devices we
