7、 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 drinking water the next day using only the heat of

8、the sun as its power source。 What makes it work is a special material called a metalorganic 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, each harvest producing onethird of a cup of pure d

9、rinking water。With further improvements， a device， the size of a washing machine, could produce enough water for the basic needs of a household, says Yaghi, a chemist at the University of California.

MOFs are also extremely stable light and have many different uses: their molecular structure can be varied to attract specifi

12、c 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。1Why is the Arizona desert mentioned in the seco

18、cularly along the coastline in spots with no railings or fences. 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“The Arizona desert is really dry。 Anyone stuck in it withou

19、t water would die from dehydration （脱水） within three days. Unless， that is, they had one of Omar Yaghis nextgeneration 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。故A选项正确2细节理解题.由第三段“What makes it work is a special material

20、called a metalorganic 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 with an extremely high absorption ability， attracting specific

21、 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 structure can be varied to attract specific molecules， s

22、uch 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。
