課 時(shí) 作 業(yè) 29.閱讀理解(2019·福建省廈門第一中學(xué)高三月考)There have been claims that warming on Mars and Pluto is proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouse gases. But we can say with certainty that, even if Mars, Pluto or any other planet has warmed in recent years, it is not due to changes in solar activity.The Sun's energy output has not increased since direct measurements began in 1978. If increased solar output really was responsible, we should be seeing warming on all the planets and their moons, not just Mars and Pluto.Our solar system has eight planets, three dwarf planets and quite a few moons with at least a thin atmosphere, and thus a climate of sorts. Their climates will be affected by local factors such as orbital variations, changes in reflectance and even volcanic eruptions, so it would not be surprising if several planets and moons turn out to be warming at any one time.One theory is that winds have recently swept some areas of Mars clean of dust, darkening the surface, warming the Red Planet and leading to further increases in windinessa positive feedback effect.Observations of the thickness of Pluto's atmosphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun. The finding confused astronomers at the time, and the cause had yet to be determined.It has since been suggested that this is due to a greenhouse effect: As it gets closer to the Sun, Pluto may warm enough for some of the methane ice on its surface to turn into a gas. This would cause further warming, which would continue for a while even after Pluto's orbit starts to take it away from the Sun.本文是一篇科普說明文，有人認(rèn)為地球變暖是因?yàn)樘柣顒?dòng)而不是溫室氣體，文章駁斥了這個(gè)觀點(diǎn)。同時(shí)對(duì)太陽系里另外一些星星的變暖情況分別進(jìn)行了分析。1What cause(s)the warming of some planets?AThe solar system.BTheir local factors.CVolcanic mountains.DThe thin atmosphere.答案：B解析：細(xì)節(jié)理解題。根據(jù)第三段第二句Their climates will be affected by local factors such as orbital variations, changes in reflectance and even volcanic eruptions可知，導(dǎo)致某些星球變暖的原因很多，可能是受到這些星球的當(dāng)?shù)匾蛩氐挠绊?。故B項(xiàng)正確。2What is the outcome of the recent winds on Mars?AThey've cooled the planet.BThey've left a clear sky.CThey've caused more winds.DThey've helped clean the planet.答案：C解析：推理判斷題。根據(jù)文章第四段One theory is that winds have recently swept some areas of Mars clean of dust, darkening the surface, warming the Red Planet and leading to further increases in windinessa positive feedback effect.可知，火星上的風(fēng)吹走了灰塵，讓火星變暖同時(shí)也會(huì)導(dǎo)致風(fēng)力的進(jìn)一步變大。故C項(xiàng)正確。3What do we know about the thickness of Pluto's atmosphere?AIt remains mysterious.BIt troubled astronauts.CIt has become thinner.DIt contributes to the warming.答案：D解析：細(xì)節(jié)理解題。根據(jù)第五段第一句Observations of the thickness of Pluto's atmosphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun.可知，冥王星厚厚的大氣層導(dǎo)致了冥王星變暖。故D項(xiàng)正確。4Which of the following might lead to the warming on Earth according to the writer?ASolar activity.BMars and Pluto.CGreenhouse gases.DThe Sun's energy output.答案：C解析：推理判斷題。根據(jù)文章第一段第一句可知有人認(rèn)為地球變暖是因?yàn)樘柣顒?dòng)而不是溫室氣體。根據(jù)第二句But we can say with certainty that, even if Mars, Pluto or any other planet has warmed in recent years, it is not due to changes in solar activity.可知，我們可以確切地說地球變暖不是因?yàn)樘栠\(yùn)動(dòng)，也就是說地球變暖是由溫室氣體導(dǎo)致的。故C項(xiàng)正確。.完形填空(2019·濟(jì)南一中模擬)I went with some colleagues from my office for a dinner in a very popular local restaurant.
