Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra (冻原) starts has been moving northward. Trees growing along the tree line must protect themselves from the cold wind. To do this, plants tend to grow horizontal (水平的) branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.‎ But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. This happens especially in places where white spruce (白云杉) grows. White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When windblown seeds end up on the tundra beyond the tree line, they finally sprout (发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But ‎ in recent years, the whole planet has been warming.‎ New trees will provide shelter for some snow. Keeping the sun's rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the air around. The extra warmth encourages even more trees to produce seeds. That further increases a forest's ability to expand. What's more, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below, which encourages trees to grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about effects on the animals that depend on frozen conditions for food and shelter.‎ ‎【篇章导读】本文是一篇说明文，文中讲述的是即使树不能走路，它们仍然在移动。文章介绍了树移动的原因，以及全球变暖对树木的影响。‎ ‎1．What is the main cause of the trees in the Arctic moving northward?‎ A．The reducing of northern tundra.‎ B．The rising temperature.‎ C．The cold and strong wind.‎ D．The rich resources in the north.‎ ‎【答案】B　‎ ‎【解析】细节理解题。根据第二段第二、三句“Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra (冻原) starts has been moving northward.”(在北极地区，温度比世界上任何地方都要上升得快。当这一切发生时，标志着森林结束和寸木不生的冻原开始的树线就一直向北移动。)可知，在北极树木向北移动的主要原因是温度升高。故选B。‎ ‎2．What does the underlined word “this” in Paragraph 2 mean?‎ A．To produce more seeds.‎ B．To move northward.‎ C．To respond to the climate change.‎ D．To protect themselves from the cold wind.‎ ‎【答案】D　‎ ‎【解析】词义猜测题。根据第二段第四句“Trees growing along the tree line must protect themselves from the cold wind.”可知，沿着树线生长的树木必须保护自己免受寒风的袭击。由此可知，此处this指的是保护它们免受寒风的袭击。故选D。‎ ‎3．What can be inferred from the last paragraph?‎ A．New trees can trap the snow, which may make the soil colder.‎ B．The trapped snow prevents new trees from producing more seeds.‎ C．New trees can make the air around warmer.‎ D．New trees can bring more food and shelter to local animals.‎ ‎【答案】C　‎ ‎【解析】推理判断题。根据第四段第一句“New trees will provide shelter for some snow.”(新的树木将为一些雪提供庇护。)和第三、四句“Instead, the trees absorb(吸收) the sun's heat. This warms the air around.”(相反，树木吸收太阳的热量，这温暖了周围的空气。)可知，新的树木可以使周围的空气更温暖。故选C。‎ B El Niño, a Spanish term for “the Christ child”， was named by South American fishermen who noticed that the global weather pattern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Niño sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.‎ The weather effects, both good and bad, are felt in many places. Rich countries gain more from powerful Niños, on balance, than they lose. A study found that a strong Niño in 201998 helped America's economy grow by $15 billion, partly because of better agricultural harvests: farmers in the Midwest gained from extra rain. The total rise in agricultural incomes in rich countries is greater than the fall in poor ones.‎ But in Indonesia extremely dry forests are in flames. A multiyear drought (干旱) in southeast Brazil is becoming worse. Though heavy rains brought about by El Niño may relieve the drought in California, they are likely to cause surface flooding and other disasters.‎ The most recent powerful Niño, in 201998, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Niños come with months of warning, and so much is known about how they happen that governments can prepare. According to the Overseas Development Institute (ODI), however, just 12% of disaster relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards. This is despite evidence that a dollar spent on risk reduction saves at least two on reconstruction.‎ Simple improvements to infrastructure (基础设施) can reduce the spread of disease. Better sewers (下水道) make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According to a paper in 2019 by Mr. Hsiang and coauthors, civil conflict is related to El Niño's harmful effects—and the poorer the country, the stronger the link. Though the relationship may not be causal， helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Niño, reducing their losses needs to be the priority.‎ ‎【篇章导读】本文是一篇说明文，文中主要介绍了厄尔尼诺现象名称的由来、发生的时间、造成的影响，督促人们加强风险前资金的投入，改进基础设施，为厄尔尼诺现象的发生做好准备。‎ ‎4．What can we learn about El Niño in Paragraph 1?‎ A．It is named after a South American fisherman.‎ B．It takes place almost every year all over the world.‎ C．It forces fishermen to stop catching fish around Christmas.‎ D．It sees the changes of water flow direction in the ocean.‎ ‎【答案】D　‎ ‎【解析】细节理解题。根据文章第一段第二句“El Niño sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.”可知，厄尔尼诺现象见证了大海中水流方向的变化。故选D。‎ ‎5．What may El Niños bring about to the countries affected?‎ A．Agricultural harvests in rich countries fall.‎ B．Droughts become more harmful than floods.‎ C．Rich countries' gains are greater than their losses.‎ D．Poor countries suffer less from droughts economically.‎ ‎【答案】C　‎ ‎【解析】细节理解题。根据文章第二段第二句“Rich countries gain more from powerful Niños, on balance, than they lose.”‎ 可知，总的来说富裕国家从强有力的厄尔尼诺现象中收获的比失去的多。故C项正确。‎ ‎6．The data provided by ODI in Paragraph 4 suggest that ________.‎ A．more investment should go to risk reduction B．governments of poor countries need more aid C．victims of El Niño deserve more compensation D．recovery and reconstruction should come first ‎【答案】A　‎ ‎【解析】推理判断题。根据文章第四段第三句“According to... (ODI), however, just 12% of disasterrelief funding in the past two decades has gone on reducing risks in advance...”可知，在过去二十年里仅有12%的灾难救济资金用于提前降低风险，因此第四段旨在说明应该投入更多的资金来降低风险。‎ ‎7．What is the author's purpose in writing the passage?‎ A．To introduce El Niño and its origin.‎ B．To explain the consequences of El Niño.‎ C．To show ways of fighting against El Niño.‎ D．To urge people to prepare for El Niño.‎ ‎【答案】D　‎ ‎【解析】推理判断题。综合全文内容并结合文章最后一段可知，本文旨在督促人们为厄尔尼诺现象做好准备
