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 dont have enough energy to make seeds.But as Earths climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all that leftover energy, these trees have started producing more seeds. 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 eventually can 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 suns rays from making the white surface disappear. Instead, the trees absorb the suns heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forests ability to expand. In addition, 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 impacts on the animals that depend on frozen conditions for food and shelter.篇章导读：本文是一篇说明文。文章介绍了北极地区森林北移的原因，以及全球变暖对树木的影响。4What is the main cause of the trees in the Arctic moving northward?AThe shrinking of northern tundra.BThe abundant resources in the north.CThe fierce and cold wind.DThe rising temperature.答案：D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.”可知，在北极地区，温度的上升比世界上任何其他地方都要快得多。当这一切发生时，标志着森林结束和冻原开始的树线一直向北移动。同时结合第四段中对森林北移的解释，可推知在北极树木向北移动的主要原因是温度升高，故选D。5What does the underlined word “this” in Paragraph 2 mean?ATo produce more seeds.BTo move northward.CTo respond to the climate change.DTo protect themselves from the cold wind.答案：D推理判断题。根据第二段第四句“Trees growing along the tree line must protect themselves from the cold wind.”沿着林木线生长的树木必须保护自己免受寒风的袭击。此处this指的是保护它们自己免受冷风的袭击，故选D。6The passage is most probably taken from _.Aa fashion magazineBa health reportCa science reportDa childrens magazine答案：C推理判断题。根据本文内容可知，主要介绍北极森林北移的原因以及全球变暖对树木的影响，属于科学研究范畴，应该归于科学报告类，故答案选C。读后续写阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。A long time ago, there lived a very, very wise king. He was so wise that he knew the ways of almost everything.Then one day, a tiny_bee lost her way and flew right into the_kings_beautiful_palace. The little bee begged the king, “Please, let me live, and I will serve you some other day.” The king was amused to think a tiny bee could one day serve such a powerful king. He released the bee and said, “Be on_your_way,_for I need nothing from you today.”Many days later, the_people_of_the_kingdom filled the palace yard. A queen was coming to visit from a faraway land. She heard many people claim this king was very wise. She had to know for sure that they were not all just lies. “I hear you are wise，” she said. “You are wiser than the rest. Would you be willing to put your wisdom to a test？” The king agreed, and she did her best with puzzles, tricks, and difficult tests, but all in vain (徒劳)Now the_queen was quite angry at the kings show of wisdom, and was more determined to find a way to trick him. “We must have a test，” she challenged her advisors, “to prove this kings a fool, not to prove he is wiser！” So they came up with a plan that would surely not fail. It indeed was a test to make the others look pale. They ordered the queens craftsmen (工匠) to make ninetynine flowers, fake (假的) through and through, but looking so real. When they are finished, even the queen could not tell they were fake. She was sure the king would make the very same mistake. And then from the kings garden, she took just one real_flower,_and cleverly hid it among all the others.注意：1所续写短文的词数应在150左右；2至少使用5个短文中标有下划线的关键词语；3续写部分分为两段，每段的开头语已为你写好；4续写完成后，请用下划线标出你所使用的关键词语。Paragraph 1：The king, not wanting to be fooled by this queen, accepted the challenge.
