Unless, that is, they had one of Omar Yaghis next-generation water harvesters. Although daytime humidity（湿度）is only about 10 per cent, thi

7、s rises to 40 per cent at night, which means theres enough water in the atmosphere to support life if it can be transformed into liquid form.Thats exactly what Yaghis device does. Its a box about the size of a small microwave oven designed to suck the humidity from the air at night and turn it into

8、drinking water the next day using only the heat of the sun as its power source. What makes it work is a special material called a metal-organic framework (MOF), which at normal temperatures attracts water molecules (分子) onto its surface of its internal pores（细孔）. Warm it up and the water is released

11、 to a variety of liquids and gases.MOFs work thanks to their unique structure-large quantities of nanometer-sized internal spaces. In fact one MOF has so many pores that they would cover an area as large as six football fields. MOFs are also extremely stable light and have many different uses: their

12、 molecular structure can be varied to attract specific molecules, such as water, and their pores can be designed to best store them. Adding a small amount of heat or pressure causes the MOF to release what it is holding. More than 70,000 different MOFs have been produced to date for various applicat

India is home to 4 highest number of people who have died while taking photos of 5 (they), with 19 of the worlds 49 recorded selfie-linked deaths since 2014.6 (early) this month, an 18-year-old college student on a c

Anyone coming into “no selfie” areas even if they take no photos, will risk a fine of 1,200 rupees ($17.50).答案及解析A【答案】1A2D3A4B【解析】这是一篇说明文。短文介绍了金属有机骨架(MOFs)的用途，结构和性能。1推理判断题。由第二段“T

19、he Arizona desert is really dry. Anyone stuck in it without water would die from dehydration （脱水） within three days. Unless, that is, they had one of Omar Yaghis next-generation water harvesters.”可知，亚利桑那沙漠非常干燥。任何没有水的人都会在三天内死于脱水。除非他们有奥马尔亚吉的下一代水收集器。所以奥马尔亚吉的下一代水收集器可以解决沙漠中缺水的问题。故判断出第二段提到亚利桑那沙漠是为了介绍水收集器。

20、故A选项正确2细节理解题。由第三段“What makes it work is a special material called a metal-organic framework (MOF).”可知，使它工作是一种称为有机框架(MOF)的特殊的材料。所以金属有机框架在水收集器中起着至关重要的作用。故D选项正确。3词义猜测题。由第五段“These crystalline cluster（结晶群）of metals, such as aluminum or magnesium, linked by organic molecules can be made into materials wit

21、h an extremely high absorption ability, attracting specific molecules to their surface. In this way, MOFs cling to a variety of liquids and gases.”可知，这些由有机分子连接的金属结晶簇，例如铝或镁，可制成具有极高吸收能力的材料，将特定分子吸到其表面。MOF就是通过这种方式紧紧吸附各种液体和气体。 所以第5段中下划线的cling to可能是 hold onto“紧紧抓住”的意思。故A选项正确。4推理判断题。由最后段“. their molecular

22、structure can be varied to attract specific molecules, such as water, and their pores can be designed to best store them. Adding a small amount of heat or pressure causes the MOF to release what it is holding. More than 70,000 different MOFs have been produced to date for various applications.”可知，它们

23、的分子解剖结构可以变化以吸附特定的分子，比如水分子，它们的孔可以设计成储存水的最佳形态。增加少量的热量或压力会使MOF释放它所持有的东西。迄今为止，已有七万多种不同的MOF被生产用于各类实际应用中。所以我们通过短文最后段的内容可以判断出，接下来的段落可能会涉及MOF科技的其它用途。故B选项正确。B【解析】这是一篇说明文。因为很多游客喜欢在印度自拍，导致印度成为自拍死亡人数最多的国家。为了阻止这一情况的恶化，印度政府采取了一些相关措施，例如设立标志牌和罚款。1考查非谓语动词。分析句子可知，设空处应用非谓语动词作状语，逻辑主语people和smile之间是主动关系，应用现在分词，故填smiling

24、。2考查不定式。分析句子可知，此处考查固定用法“主语 + be said/ thought/ believedto do sth.”，故填to love。3考查形容词。分析句子可知，此处应用variety的形容词various“各种各样的”修饰名词leaders，故填various。4考查定冠词。由highest可知此处应填定冠词，表示最高级，故填the。5考查代词。句意：印度是因自拍照死亡数字最高的地方。根据句意可知，此处意为“自拍”即给自己拍照，故应用反身代词指代上文提到的people，故填themselves。6考查比较级。句意：本月早些时候，一个18岁的大学生班级野餐时，站在一个大坝附

25、近的岩石上自拍失去了平衡。根据句意可知，此处意为“本月早些时候”，应用early的比较级earlier，故填Earlier。7考查定语从句。分析句子可知，设空处引导定语从句，修饰先行词a classmate，关系词代替先行词，在从句中作主语，指人，应用关系代词that/who，故填that/ who。8考查时态。分析句子可知，设空处是句子谓语动词，根据上文的since then判断为现在完成时，主语the Indian government是第三人称单数，谓语动词用单数，故填has declared。9考查短语。此处是短语warn sb. against doing sth.“警告某人不要做某事”，故填against。10考查形容词。设空处应填形容词作为表语，故填risky。
