So Many "Earths"
The Milky Way (銀行) contains billions of Earth-sized planets that could support life. That's the finding of new study. It draws on data that came from NASA's 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 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 liquid.
The new estimate of how many planets 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 applied 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 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.

16.c。題干：Kepler太空望遠(yuǎn)鏡已經(jīng)使用15年了。利用題干關(guān)鍵詞Kepler和15進(jìn)行定位，發(fā)現(xiàn)第二段談及“A mechanical failure recently put that Kepter space telescope out of service”，即“技術(shù)的故障使得Kepler太空望遠(yuǎn)鏡不能再使用了”，但是沒有提及Kepler太空望遠(yuǎn)鏡的使用時(shí)間，故答案為C。
17.A。題干：Kepler太空望遠(yuǎn)鏡的主要任務(wù)就是找到與地球情況類似的行星。利用題干關(guān)鍵詞Kepler和Earth等可以定位到第二段“The telescope focused on hunting planets that might have conditions similar to those on Earth.”。由此可知，題干信息與原句信息一致，故答案為A。
18.B。題干：能支持生命的行星可能比地球要小一點(diǎn)。利用題干關(guān)鍵詞support life和smaller進(jìn)行定位，可以定位到第三段“…14 and 300ut 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”，即“據(jù)我們所知，每100個(gè)恒星之中約有14～30個(gè)恒星有著與太陽(yáng)相似的體積和溫度，可能支持行星上的生命，這樣的行星直徑至少與地球直徑一樣大或者最大不超過(guò)地球直徑的兩倍”。由此可知，題干信息與原句信息不一致，故答案為B。
19.A。題干：地球行星是圍繞太陽(yáng)的可居住區(qū)域內(nèi)的軌道運(yùn)行。利用題干關(guān)鍵詞orbit和habitable zone等可以定位到第三段“The planet also would have to orbit in a star’s habitable zone.”，即“這樣的行星也必須在恒星的可居住區(qū)域內(nèi)的軌道運(yùn)行”，并結(jié)合上一句可知，能支持生命的行星需要在像太陽(yáng)這樣的恒星的可居住區(qū)域內(nèi)運(yùn)行。由此可知，題干信息與原句信息一致，故答案為A。
20.B。題干：新發(fā)現(xiàn)是基于對(duì)銀河系中17萬(wàn)顆恒星的全部研究。利用題干關(guān)鍵詞new finding和170000并結(jié)合題目順序與段落順序一致的原則，可以定位到第四段“The new estimateof how many planets might fit these conditions comes from studying more than 42，000 stars…”，即“有關(guān)多少行星符合這種情況的預(yù)測(cè)是來(lái)自于對(duì)42000多顆恒星的研究……”。由此可知，題干信息與原句信息不一致，故答案為B。
21.A。題干：關(guān)于可以支持生命的行星數(shù)量的預(yù)測(cè)是不準(zhǔn)確的。利用題干關(guān)鍵詞estimate和accurate等可以定位到第四段和第五段“The new estimate ofhow many planets might fit these conditions…The estimate is rough，the authors admit”，即“這項(xiàng)對(duì)于符合這些情況的行星的數(shù)量的預(yù)測(cè)……作者承認(rèn)這種預(yù)測(cè)是比較簡(jiǎn)單的”。由此可知，題干信息與原句信息一致，故答案為A。
22.C。題干：這是有關(guān)有生命存在可能性的行星的最早的研究發(fā)現(xiàn)。利用題干關(guān)鍵詞first和chance for life等可以定位到最后一段“It would mean however that the Milky Way could host more than a billion Earth-sized planets with a chance for life”，即“但是這意味著銀河系中有超過(guò)十億顆地球大小的行星都有生命存在的可能性”，但是沒有提及是否是最早的發(fā)現(xiàn)，故答案為C。
