It draws on date that came from NASAs top planet-hunting telescope. A mechanical failure recently put that Kepler space t
7、elescope 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 a
8、uthors 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 a
9、s Earths, 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 ide
10、ntifying suitable worlds orbiting them. The scientists used those numbers to extrapolate 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 and
11、 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 to co
12、mplete 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. 16. The Kepler space telescope has been in service for 15 years. A. Right B. Wrong C. Not m
13、entioned 17. The main task of the Kepler space telescope is to find out planets with similar conditions to Earths. A. Right B. Wrong C. Not mentioned 18. The planet that could support life might be a little bit smaller than Earth. A. Right B. Wrong C. Not mentioned 19. The Earth is planet orbiting i
14、n the Suns habitable zone. A. Right B. Wrong C. Not mentioned 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 21. The estimate of the number of planets that could support life is not very accurate. A. Right B. Wrong C. Not mentio

Not mentioned 第3部分:概括大意和完成句子(第2330题,每题1分,共8分) 下面的短文后有2项测试任务:(1)第23 26题要求从所给的6个选项中为指定段落每段选择1个小标题;(2)第27 30题要求从所给的6个选项中为每个句子确定一个最佳选项。 Climate Change: The Long Reach 1 Earth is warming. Sea levels
16、are rising. Theres more carbon in the air, and Arctic ice is melting faster than at any time in recorded history. Scientists who study the environment to better gauge (评估) Earths future climate now argue that these changes may not reverse for a very long time. 2 People burn fossil fuels like coal an
17、d 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 dioxide released, the more the planet warms. If current consumption of fossil fuels doesnt slow, the long-term climate impacts could last thousands of years
18、 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 or so. During that time, changes in the planets environment
19、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 imp
20、acts is called a “fast feedback.”. 4 Zeebe says its important to look at fast feedbacks. However, he adds, theyre 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 ne
21、w study, Zeebe now 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 comfortable areas are two examples of slow feedbacks. 5
22、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
23、 only fast feedbacks predict a 4.5 degree Celsius (8.1 degree Fahrenheit) change by the year 3000. But slow feedbacks added another 1.5 C for a 6 total increase, Zeebe reports. He also found that stow feedback events will cause global warming to persist for thousands of years after people run out of
