Now, new research suggests that a simple, cheap measure may significantly reduce the level of microplastics in water from your tap (水龙头): boiling and filtering (过滤) it.In a study published Wednesday in Environmental Science & Technology Letters, researchers from China found that boiling tap water for just five minutes—then filtering it after it cools—could remove at least 80 percent of its microplastics. Crucially, this process relies on the water containing enough calcium carbonate (碳酸钙) to trap the plastics.In the study, boiling hard water containing 300 milligrams of calcium carbonate led to an almost 90 percent drop in plastics.But in samples with less than 60 milligrams of calcium carbonate, boiling reduced the level of plastics by just 25 percent.Additionally, the research didn't include all types of plastics.The team focused only on three common types—polystyrene, polyethylene and polypropylene—and they didn't study other chemicals previously found in water such as vinyl chloride. Still, the findings show a potential path forward for reducing microplastic exposure—a task that's becoming increasingly difficult.Even bottled water, scientists found earlier this year, contains 10 to 1，000 times more microplastics than originally thought. Scientists are still trying to determine how harmful microplastics are—but what they do know has raised concerns.The new study suggests boiling tap water could be a tool to limit intake.“The way they demonstrated how microplastics were trapped through the boiling process was nice，” Caroline Gauchotte­Lindsay, an environmental engineer at the University of Glasgow in Scotland who was not involved in the research, tells New Scientist.“We should be looking into upgrading drinking water treatment plants so they remove microplastics.” 1．How does the author present the issue in the first paragraph? A．By quoting an expert. B．By defining a concept. C．By giving examples. D．By providing statistics. 2．What determines the effectiveness of trapping microplastics in water? A．The hardness of water. B．The length of cooling time. C．The frequency of filtering. D．The type of plastic in water. 3．What does the author try to illustrate by mentioning bottled water in Paragraph 4? A．The importance of plastic recycling. B.The severity of the microplastic problem. C．The danger in overusing pure water. D．The difficulty in treating polluted water. 4．What is Gauchotte­Lindsay's suggestion about? A．Choice of new research methods. B．Possible direction for further study. C．Need to involve more researchers. D．Potential application of the findings. 命题角度——间接信息题：隐含含义、言外之意(对接T3) 【设题特点】 ① 题干常以imply、suggest、infer、illustrate等词汇明确考查“言外之意”，要求从原文表述中推导未直接说明的信息，而非抓取表层内容。 ② 待推断的含义不直接呈现，需结合文本细节(如人物对话、具体案例)或逻辑关系(如转折、因果)挖掘。 ③ 正确选项需精准还原作者未明说但可推导的深层含义，且不偏离段落核心话题；错误选项多为“过度解读”(超出文本逻辑的主观推测)或 “与隐含信息相悖”。 【破题思路】 【语篇解读】　本文是一篇说明文。文章介绍了微塑料污染的普遍性，并介绍了中国研究人员的新发现：煮沸并过滤自来水可去除水中的微塑料。 1．C　推理判断题。第一段中作者通过列举微塑料在深海、喜马拉雅山脉、火山岩石、海鸟胃里和南极洲下的雪中的存在来呈现微塑料污染问题。因此，作者是通过举例子的方式来呈现问题的。故选C。 2．A　细节理解题。根据第三段第一句“Crucially, this process relies on the water containing enough calcium carbonate (碳酸钙) to trap the plastics.”可知，水的硬度决定了聚集水中微塑料的效果。下文补充说将含有300毫克碳酸钙的硬质水煮沸可使微塑料含量降低近90%，但将碳酸钙含量低于60毫克的样本煮沸仅使微塑料含量降低了25%。因此，水的硬度是影响聚集微塑料效果的关键因素。故选A。 3．B 4．D　推理判断题。最后一段中提到“We should be looking into upgrading drinking water treatment plants so they remove microplastics.”，这表明Gauchotte­Lindsay的建议与研究结果的潜在应用有关。故选D。 1．语境辨义(写出下列黑体词在文中的词性及含义) ① (合成词)Microplastics have become a common source of pollution across the Earth._________ ② (合成词)The new study suggests boiling tap water could be a tool to limit intake._________________ ③ (合成词/熟词生义)We should be looking into upgrading drinking water treatment plants so they remove microplastics.________　_____ 2．词块积累(写出下列词块在文中的汉语意思) ① across the Earth 　 ______________________ ② tap water ______ ③ rely on __________ ④ bottled water ______ ⑤ raise concerns __________________ ⑥ be involved in __________ 1．In a study published Wednesday in Environmental Science & Technology Letters, researchers from China found that boiling tap water for just five minutes—then filtering it after it cools—could remove at least 80 percent of its microplastics. 抓标志：过去分词 _________，从属连词 ____ 判类型：地点状语(含过去分词作后置定语)＋主句＋that引导的宾语从句作found的宾语 试翻译：____________________________________________________________ ________________________________________________________________________ 发表于周三《环境科学与技术快报》的一项研究中，中国研究人员发现，将自来水煮沸仅五分钟——待其冷却后过滤——可去除其中至少80%的微塑料。 2．The team focused only on three common types—polystyrene, polyethylene and polypropylene—and they didn't study other chemicals previously found in water such as vinyl chloride. 抓标志：并列连词 ___，过去分词 _____ 判类型：分句1＋and＋分句2 试翻译：_____________________________________________________________ _________________________________________ 该团队仅聚焦于聚苯乙烯、聚乙烯和聚丙烯这三种常见类型，且未研究此前在水中发现的其他化学物质，如氯乙烯。 3．Scientists are still trying to determine how harmful microplastics are—but what they do know has raised concerns. 抓标志：引导词 ___，并列连词 ___，引导词 ____ 判类型：分句1(含有how引导的宾语从句)＋but＋分句2(含有what引导的主语从句) 试翻译：____________________________________________________________ ____________ 科学家们仍在试图确定微塑料的危害程度，但他们目前已知的信息已引发了担忧。 4．“The way they demonstrated how microplastics were trapped through the boiling process was nice，” Caroline Gauchotte­Lindsay, an environmental engineer at the University of Glasgow in Scotland who was not involved in the research, tells New Scientist. 抓标志：引导词 ___，关系代词 ___ 判类型：直接引语作宾语(含有省略that/in which的定语从句)＋主句(同位语中含有who引导的定语从句) 试翻译：____________________________________________________________ ________________________________________________________________________ “他们巧妙地演示了微塑料在煮沸过程中是如何被截留的，”未参与该研究的苏格兰格拉斯哥大学环境工程师卡罗琳·高肖特­林赛向《新科学家》表示。 (一)应用文写作[低碳生活＋投稿] (山西省高三上学期10月月考)假如你是光明中学的学生李华，你将参加一个以“低碳生活，我们的责任与行动”为主题的征文活动，请你投稿，内容包括：1.环境现状及重要性；2.提出切实可行的建议；3.呼吁大家积极响应。 注意：1.写作词数应为80左右； 2．可以适当增加细节，以使行文连贯。 应用单元知识完成写作(黑体词为单元词汇) [写作构思链]　引入话题→点明环境现状与保护地球的重要性→提出切实可行的低碳建议→呼吁大家积极响应 ① ___________________________________________ (由于过量的碳排放与污染), the current environmental situation is alarming.Millions of species, from mammals to insects, struggle to survive, and ② ___________________________ (它们的栖息地遭到破坏), leading to their extinction.Thus, ③ ________________________________ __________________ (保护我们的地球绝对是我们的责任).
