【正文】 和尊敬地位高而又無害于他人的人，這似乎是一種天性，即使是蹣跚學(xué)步的孩子也是如此。根據(jù)第一段中的“A recent study published in Nature Human Behaviour showed that we seem to have an innate（天生的）preference for highranking peoples—but only if those people aren39。故選B。根據(jù)第二段中的“Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.”可知，蹣跚學(xué)步的孩子喜歡那個被允許通過的木偶，是因為這種行為代表著受人尊敬，孩子們更喜歡受尊敬的人。 （3）考查推理判斷。由此可推斷出，人們天生不喜歡不友善的行為。 （4）考查推理判斷。由此可推斷出，我們鼓勵孩子去贏的同時，提醒他們要體諒他人。 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科教類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。 In areas like the Central United States that get lots of tornadoes, there39。t quite as simple as that, but scientists have found that if you see a green sky, you should probably go inside. As far as most scientists can tell, the green skies around powerful thunderstorms are usually a bination of red sunsets and water droplets.s ing from everywhere. Meanwhile, around sunset sunlight travels through so much atmosphere that just about all the blue is bounced away from the horizon, leaving all those reds and oranges behind. The sunset might look exclusively （獨有的）red and orange, but there39。s where water es in. Still, none of the conditions that can turn skies green are unique to the clouds that produce tornadoes. Sometimes they just lead to lots of rain, and maybe some hail. So if you see huge storm clouds rolling in and a green tint （色調(diào)）in the sky, it doesn39。s about to be a tornado, but it does mean you should probably head indoors.（1）What can be the best title for the text? A.Do Green Skies Mean a Coming TornadoC.Green Skies Are Unique to Clouds（2）Why are the skies blue in the daytime? A.Because there is more blue light than light of other colors.C.Because red light is weaker than blue light.（3）What does the underlined word it in paragraph 2 refer to? A.Red light.C.Water.（4）What can we learn about from the text? A.Water can reflect red light as well as blue light.C.If you see a green sky, there will be a tornado.【答案】 （1）B（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，科學(xué)家發(fā)現(xiàn)天空呈現(xiàn)綠色并不是產(chǎn)生龍卷風(fēng)的云層所獨有的，有時它們會導(dǎo)致大量降雨，甚至冰雹，待在室內(nèi)或許是最好的選擇。通讀全文，根據(jù)第一段中的“there39。 （2）考查細(xì)節(jié)理解。故選C。根據(jù)第二段中的“The sunset might look exclusively （獨有的）red and orange, but there39。 （4）考查推理判斷。s where water es in.”可知，水既能反射藍(lán)光，也能反射紅光，故選B。3．犇犇閱讀理解 The crew of the Nautilus, a private research ship, recovered the rock particles(顆粒).The Nautilus is operated by the Ocean Exploration Trust. The group says its aim at present is to examine areas of the ocean that have never been explored before. The Nautilus is equipped with two remotely operated vehicles(ROVs), called Hercules and Argus. These robotic submarines help researchers find and collect materials from the seafloor. The fact that the particles landed in the ocean, instead of on land, means larger pieces may have survived and can be studied. For this reason, scientists decided to launch the first intentional search for meteorites from the ocean. Until the latest research, scientists had only accidentally discovered a small number of meteorites from drilling operations.To recover the rock particles.To observe movements of the universe.C.D.A huge meteor shower.B.Plenty of natural resources.The brainstorm of researchers.（3）Why do the scientists prefer to search for meteors in the ocean? A.B.They like to explore strange sea areas.They have better submarine equipment.（4）What does the author intend to do in the last paragraph? A.Give reasons to support a guess.C.Describe the process of the search.【答案】 （1）C（2）A（3）B（4）B 【解析】【分析】本文是一篇說明文，科學(xué)家們發(fā)現(xiàn)了他們認(rèn)為是去年墜落地球的流星碎片。一場巨大的流星雨導(dǎo)致了在海中搜索的開始。 （1）考查細(xì)節(jié)理解。故選C。根據(jù)第一段中的“Scientists have found what they believe are pieces of a meteor(流星)that fell to the earth last year.”可知，一場巨大的流星雨導(dǎo)致了在海中搜索的開始。 （3）考查推理判斷。故選B。根據(jù)最后一段中的“The objects recovered from the bottom of the sea likely came from the recent explosion for two main reasons.”可知，作者在最后一段是想給出支持猜測的理由。 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。 Environmental experts warn that our planet is drowning in plastic.s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Loop is the idea of Terra Cycle, an Americanbased recycling pany. Its chief, Tom Szaky told the Associated Press (AP) that removing plastics from the ocean is not enough. He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. But Morgan questioned whether panies worldwide are ready to change their business models.Provide background information.B.Explain the reason for trash.D.The World Economic Forum.Demand of some panies.C.D.United States and Switzerland.B.Canada and Britain.France and Canada.（4）What is the text mainly about?
