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 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 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.If 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 to 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.The new finding is based on a thorough study of 170,000 stars in the Milky Way.
A:Right
B:Wrong
C:Not mentioned答案：B解析：本篇文章只在第二段第一句表明，近来一次机械故障使开普勒太空望远镜不再为我们服务，并没有提到开普勒太空望远镜为我们服务了多少年。
第二段最后一句表明，开普勒太空望远镜主要寻找与地球有相似环境的星球。
第三段第二句表明，可让生命存在的星球的直径至少与地球的直径一样大，但不会超过地球直径的两倍。由此可推测出其不会比地球小，因此题干表述错误。
第三段第三、四句表明，适合生命存在的星球必须与它所环绕的恒星有一个合适的距离，以保证星球表面的温度允许液态水存在，而地球正是适合人类居住的星球，而且地球是绕着太阳运行的。
第四段第一句表明，这项新评估源于对超过4.2万颗星球的分析，而非源于对17万颗星球的分析。
第五段第一句表明，研究者承认这项评估是粗糙的，即不精确的。
文章第一段指出，这次的调查结果是新的发现，但通篇文章并未提到这是对可能有生命存在的星球的首次研究。 -

第二篇
Human and the Earth
In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?Who use more available resources according to the passage?
A:Rich people on Earth.
B:Poor people on Earth.
C:People in developed countries.
D:People in developing countries.答案：C解析：文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。 -

Where Did the Earth's Water Come From?
Earth is located within the"snow line"of the solar system,the region closest to the Sun where H2 0 is primarily in liquid or gaseous form,if at all.______(46)The snow line phenomena is reflected in the water content of planets like Mercury,Venus,and Mars. Water is absent on Mercury.On Venus,H2O only exists as a trace element in the atmosphere.Mars only has a thin veneer of ice in its polar regions.In general,water is rare within the snow line.
Why does Earth have so much water relative to the other inner planets?71%of the surface is covered in the oceans,more than half of which is deeper than 3,000 meters,with an approximate total volume of 1.3 billion cu km.______(47)
There are various theories as to where all the Earth's water came from,but several theories have fared better than the others.______(48)When the Earth was in the process of forming,with a radius just 40%smaller than at present,it would have had enough gravity to hold on to a tenuous atmosphere with water vapor. The first water vapor on the planet would have come from the planet's internals,where volatile(low weight)chemicals would have a tendency to float to the top,and heavy chemicals(iron and nickel)would sink.
Though the first of Earth's water came about through volcanism,this alone probably didn't produce enough to form stable pools on the surface.______(49)Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth's water comes from asteroids.
Throughout its history,Earth's water has increased in volume due to biological processes. In the early seas of Earth,hydrogen sulfide would have been in great supply,which,when reacted with carbon dioxide from the atmosphere during photosynthesis in sulfide-reducing bacteria,would have produced hydrogen,sulfur,and water.______(50)________（49）
A: More water was added to the planet during several hypothesized large impacts from asteroids from the outer asteroid belt.
B:We know that the oceans existed as early as 100 million years after the formation of the Earth.
C:Still,the oceans only make up 0.023%of the Earth's total mass.
D:Astronomers say Earth s water may have come from space.
E:The snow line is located in the outerasteroid belt,between the orbits of Mars and Jupiter.
F: Many geologists believe that the majority of Earth's water generated through this process.答案：A解析：文中第一段第一句提到了snow line，接下来的依据肯定还是要对snow line进行进一步说明，而选项中，只有E选项提到了snow line，所以选择E。
文中第二段主要说明地球上的水占的比重，而只有C选项是对这一主题进行说明，所以选择C。
根据后一句When the Earth was in the process of forming可以得知，该段是在讲述地球的形成历史，B选项We know that the oceans existed as early as 100 million years after the formation of the Earth也是在讲述地球形成的历史，所以选择B。
后一句：Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth's water comes from asteroids．通过把地球上水的同位素和小行星以及彗星上的水的同位素进行比较，发现地球上的水主要来自小行星。可以推断出，该句要讲述地球上的水与太空中小行星的关系，所以A选项正确。
文中的最后一段主要是讲地球上水的来源。前一句：In the early seas of Earth,hydrogen sulfide would have been in great supply,which,when reacted with carbon dioxide from the atmosphere during photosynthesis in sulfide-reducing bacteria,would have produced hydrogen , sulfur , and water．在地球早期的海洋中，硫氢化合物非常丰富，在去硫细菌的光合作用的影响下，它与大气层中的二氧化碳产生化学反应，产生大量的氢、硫，以及水。这是地球自身产生的水，而F选项Many geologists believe that the majority of Earth's water generated through this process(许多地理学家认为地球上水的产生主要通过这一进程实现）正好承接前一句，所以F选项正确。 -

单选题The greatest chance for the existence of extraterrestrial life is on a planet beyond our solar system. The Milky Way galaxy alone contains 100 billion other suns, many of which could be accompanied by planets similar enough to Earth to make them suitable abodes of life. The statement above assumes which of the following?ALiving creatures on another planet would probably have the same appearance as those on Earth.
BLife cannot exist on other planets in our solar system.
CIf the appropriate physical conditions exist, life is an inevitable consequence.
DMore than one of the suns in the galaxy is accompanied by an Earth-like planet.
EIt is likely that life on another planet would require conditions similar to those on Earth.

文段从其他行星与地球环境相似，推出其他行星上有生命存在的结论，所以可知作者暗示生命体的存在需要和地球相类似的生存条件，故本题应选E项。 -
第20题：
问答题Not so long ago, people talked about global warming in apocalyptic terms—imagining the Statue of Liberty up to its chin in water or an onslaught of tropical diseases in Oslo. Recently, however, advances in our understanding of climate have moved global warming from a subject for a summer disaster movie to a serious but manageable scientific and policy issue. The greenhouse effect is nothing new; it has been operating ever since the earth formed. Without it, the surface of the globe would be a frigid –20 ℃ (–4 °F), the oceans would have frozen, and no life would have developed.正确答案：
不久以前,人们提及全球变暖往往被认为是危言耸听,要么说水面上升会淹及自由女神像的下巴,要么说寒冷的挪威首都奥斯陆会遭到热带疾病的袭击。近来,我们对于气候的了解更加深入,全球变暖不再是一场炎夏的灾难,而是一个严重却可以控制和解决的科学和政策问题。温室效应并不是新现象,地球形成后就在发生。没有温室效应,地球表面的温度会低至零下20摄氏度(零下4华氏度),海洋会结冰,没有生命会产生。解析： 暂无解析 -

单选题We can safely conclude that ______.Apeople in the 19th century were eager to eat sugar
Bif shipwrecked sailors had drunk fresh water, things would have been even worse
Cone or more scientists have been hired to cheat in regard to sugar
Dscientists can do nothing without the money subsidized secretly
正确答案： A解析：
文中倒数第二段提到“……reported to the House of Commons that a prize of twenty-five guineas had been offered to anyone who could come up with the most “satisfactory” experiments to prove that unrefined sugar was good for feeding and fattening oxen”，即那些能证明糖类有好处的人会得到奖赏，由此推断一些科学家是被收买了以证明糖类有好处，C项正确。
