Scientists, from Nature studied 20 years of satellite data of the world’s 220,000 mountain glaciers, and found that since 2015, glaciers have last 298 billion metric tons of ice and snow per year. That is 31% more than 15 years ago, and enough ice melt to put Switzerland under 7.2 meter of water each year. Scientist say the melting is caused by climate（气候）change. Almost all of the world’s glaciers are melting. Half of the world’s glacier melts in the United States and Canada. Some miller glaciers are totally lost. The melting “mirrors” the worldwide increase in temperature and is from the burning of coal, oil and gas. Shrinking（缩小）glaciers are a problem for million is of people who use regular glacier melt for drinking water. Very fast melting can also cause floods（洪水）in places like India. But the biggest problem to the world is rising sea levels, Glaciers are responsible for 21% of sea level rise. Mark Serreze, director of the American National Snow and Ice Data Center（NSIDC）in Colorado, thinks that sea level rise is going to be a bigger and bigger problem, as we move through the 21st century. Scientists said that it could take hundreds of years to regrow melted glaciers. Twila Moon studies glaciers at the NSIDC. “I’m not sure whether the glaciers can regrow even if the planet’s temperature is controlled. We must try to keep much ice possible and slow the speed of glacier melting.” she said.1. According to the passage, glacier melting is caused by ________.A. climate change B. water pollution C. sea level rise D. serious floods2. ________ of the glacier melt around the world is in the United States and Canada.A. 21% B. 31% C. 50% D. 80%3. What is the main idea of paragraph 3 A. The world’s glaciers are melting quickly. B. Some smaller glaciers are completely lost.C. The world’s glacier melting causes some problems. D. People need to find ways to deal with glacier meting.4. We can guess that Twila Moon might be ________ about glacier regrowing.A. excited B. surprised C. angry D. worried5. The passage is probably from ________.A. a sports newspaper B. a science magazineC. a story book D. a travel guide三、六选五We have found plastic in the ocean and in animals like birds, fish and whales. But for the first time, scientists have found plastic in human poop (大便) , USA Today reported. The findings came from a study led by scientists from Environment Agency Austria 1 The volunteers wrote down what they ate for a week and then provided a stool sample (大便样本) for testing. 2 About 20 small plastic particles (IM) were found in every 10 grams (克) of stool. "The smallest plastic particles can enter the blood, the lymphatic system, and may even reach the liver (肝脏)," said Philipp Schwabl, who took part in the research. 3 They’re not sure how the plastic got in the volunteers' bodies, either. But most of the volunteers said they drank from plastic bottles and also ate seafood that could include plastic from ocean pollution.In fact, plastic is everywhere around us. Every year, lots of plastic waste goes into the ocean. 4 Most of the particles stay in the ocean. Others can spread into the soil. and air. Could plastic in the air fall onto food and get into the human body Some past studies may also give us a clue. 5 And even some drinking water has been found to have tiny plastic particles in it.根据短文内容从方框中选出五个句子填入文中空缺处使短文内容通顺完整。A．There, sunlight and waves (海浪) break the plastic waste down to very small pieces.B．The scientists are sure that the plastic must be harmful to humans.C． According to USA Today, 90% of sea salt which is sold in the world includes plastic.D．The scientists followed eight healthy volunteers from different parts of the world.E. However, the scientists aren't sure if the plastic is harmful to humans.F. Scientists found nine different kinds of plastic in the stool samples, according to the study.四、选词填空 从下面方框中选择恰当的词或短语并用其正确形式填入短文中,使短文通顺正确(每个词或短语只用一次)。get worse, use, other, soil, animal, cut down, because, take action, nature, thanIt's very important that we all recycle things.

Since the 1950s, the amount (数量) of water that people use has 3 (increase) by three times. But the water supply (供应) hasn’t. Scientists worry that soon there won’t be enough water for 4 (we). I am afraid we have to pay 5 this. What can we do to help Use water 6 (wise). Not having enough water isn’t our only problem. We must try to make it clean first.

B【解析】本文主要讲述了全球各地的冰川都在融化，分析了冰川融化的原因及会带来的问题。1. 细节理解题。根据“Scientist say the melting is caused by climate change.”可知，冰川融化是由气候变化引起的。故选A。2. 细节理解题。根据“Half of the world’s glacier melts in the United States and Canada.”可知，世界上一半的冰川融化在美国和加拿大。故选C。3. 段落大意题。根据“Very fast melting can also cause floods in places like India. But the biggest problem to the world is rising sea levels...”可知，第三段主要关于冰川融化会带来的问题。故选C。4. 推理判断题。根据“I’m not sure whether the glaciers can regrow even if the planet’s temperature is controlled. We must try to keep much ice possible and slow the speed of glacier melting.”可知，Twila Moon很担心冰川能否再生。故选D。5. 主旨大意题。阅读全文可知，本文主要讲述了全球各地的冰川都在融化，分析了冰川融化的原因及会带来的问题，所以这篇文章最可能来自于科学杂志。故选B。三、六选五【答案】1．D 2．F 3．E 4．A 5．C【分析】我们在一些海洋动物中发现了塑料，而且最近科学家在人类粪便中也发现了塑料。为此科学家对一些志愿者做了实验，证明确实人体中含有塑料，并说明了塑料是如何进入海洋动物和人体的。1．根据后文The volunteers wrote down what they ate for a week….既然这里提到志愿者，所以是科学家们对一些志愿者们进行了研究，结合选项这和D选项“科学家们跟踪了来自世界各地的八名健康志愿者”内容是一致的，故选D。2．因为前文提到了科学家对8名志愿者进行了研究，所以这里要对研究结果进行说明，所以F “根据这项研究，科学家在粪便样本中发现了九种不同的塑料”，是研究结果，故选F。3．根据后文They’re not sure how the plastic got in the volunteers' bodies, either. 他们也不确定塑料是如何进入志愿者体内的。这里提到了“也不确定”，所以前文是“不确定….”, 故这和E中“不确定塑料是否对人类有害”是对应的，故选E。4．根据前文Every year, lots of plastic waste goes into the ocean. 每年都有大量的塑料废料流入海洋。所以这里要说明塑料进入海洋之后发生了什么，故这和A选项“在那里，阳光和海浪把塑料垃圾分解成很小的碎片。”是对应的，故选A。5．根据后文even some drinking water has been found to have tiny plastic particles in it. 提到甚至在一些饮用水中也发现了塑料颗粒，所以这里在说“在….中存在塑料颗粒”，故这和C选项中的“90% of sea salt which is sold in the world includes plastic.”是对应的，故选C。四、选词填空【答案】1.used 2.other 3.animals 4.soil 5.get worse 6.because 7.natural 8.than 9.cut down 10.take action 逐题详细解析1. used原词：use形式：被动语态 can be used（能被使用）句意：在自然界中，所有东西都可以被再次使用。2. other原词：other用法：other animals 其他动物句意：当一只动物死去，它会成为其他动物的食物。3. animals原词：animal形式：复数 animals（泛指，不止一种）句意：我们的垃圾杀死动物，污染水和土壤。4. soil原词：soil意思：土壤句意：污染水和土壤。5. get worse原词：get worse用法：will + 动词原形句意：问题只会变得更糟。6. because原词：because用法：引导原因状语从句句意：我们应该清理垃圾，因为大自然自己做不到。7. natural原词：nature形式：形容词 natural 修饰名词 materials句意：地球有丰富的天然材料。8. than原词：than用法：more… than… 比…… 更多句意：我们使用的天然材料比地球能再生的更多。9. cut down原词：cut down意思：砍伐句意：每年我们砍伐超过 6000 平方公里的森林。10. take action原词：take action用法：let’s + 动词原形句意：所以让我们立刻采取行动。短文填空【答案】1,。because 2．an 3．increased 4．us 5．for 6．wisely 7．factories 8．harmful 9．take 10．best【导语】本文介绍了水资源对我们的重要性，以及它现在所面临的问题，呼吁人们要珍惜水资源。1．句意：我们的星球看起来很蓝，因为水几乎覆盖了地球表面的四分之三。根据“water covers almost three quarters of the Earth’s surface”可知，水几乎覆盖了地球表面的四分之三是地球看起来很蓝的原因，因此应用连词because来引导原因状语从句。故填because。2．句意：水不仅是我们星球的重要组成部分，也是我们身体的一部分。此处表泛指，且important为元音音素开头的单词，其前应用不定冠词an来限定。故填an。3．句意：自20世纪50年代以来，人们的用水量增加了三倍。根据“Since the 1950s”和“has”可知句子应用现在完成时，因此应用increase的过去分词increased。故填increased。4．句意：科学家们担心很快就会没有足够的水给我们。介词for后接人称代词we的宾格us。故填us。5．句意：恐怕我们得为此买单。pay for“为……支付”，故填for。6．句意：理智地用水。use为动词，此处应用wise的副词wisely来修饰动词use。故填wisely。7．句意：现在，船舶和工厂正在将废物排入海洋、河流等。根据谓语动词are可知此处应用factory的复数形式factories。故填factories。8．句意：污染会使水变得不能饮用，甚至对人类有害。be harmful to“对……有害”，故填harmful。9．句意：我们必须采取行动来阻止它。情态动词must后接动词原形，故填take。10．句意：这是保护水资源的最佳方式。根据定冠词the可知此处应用形容词good的最高级best。故填best。
