Professor Omar Yaghi is one of the scientists. He has created a special device (装置). It can collect water from the air. Even in very dry places, like deserts, it can still work well. In a recent test in Death Valley, one of the hottest places on Earth, the device successfully collected water. The secret lies in the special materials in the device. These materials can catch water vapour (水蒸气) from the air, even when the air is very dry. The device then turns the water vapour into clean and safe drinking water. Each device can make up to 1,000L of water a day. Besides, it consumes very little energy and can work without being connected to power systems. Yaghi’s idea comes from his own childhood experiences. He grew up in a very dry place. People there received water only once every few weeks. These early experiences never left him. They made him realize how valuable water is and inspired him to find a better way to get it. The device can help people in dry places and natural disaster areas. For example, after typhoons or floods, clean water is often hard to get. This device can provide water quickly in such situations. It brings hope to a lot of people and shows how science can help solve real-world problems. 41．How does the writer begin the text? A．By telling a story. B．By introducing a fact. C．By discussing a problem. D．By describing a scientist. 42．What does the success of the test in Death Valley show? A．The device works best in hot areas. B．The device needs heat to collect water. C．The device needs more testing in the future. D．The device can work in very hard conditions. 43．What does the underlined word “consumes” in Paragraph 3 mean? A．Uses. B．Creates. C．Stores. D．Saves. 44．Why does the writer mention Yaghi’s childhood experiences? A．To explain how he became a scientist. B．To show why he chose the special materials. C．To show how different he is from other scientists. D．To explain why he wanted to solve water problems. 45．What’s the best title for the text? A．The power of nature. B．A meaningful invention. C．A serious real-world problem. D．The value of a great scientist. 学科网（北京）股份有限公司 参考答案 题号 1 2 3 4 5 6 7 8 9 10 答案 B A C A D A B C B C 题号 11 12 13 14 15 16 17 18 19 20 答案 B A C D B A A B C D 题号 21 22 23 24 25 26 27 28 29 30 答案 A B B C A A C C B D 题号 31 32 33 34 35 36 37 38 39 40 答案 B A B D C B C A A C 题号 41 42 43 44 45 答案 B D A D B 1．B 2．A 3．C 4．A 5．D 6．A 7．B 8．C 9．B 10．C 本文主要介绍了中国科学家研发的“Beinao-1”设备。该设备通过接收大脑信号并转化为机器指令，成功帮助残疾人重新站立、交流和用意念控制事物，体现了中国强大的高科技实力。 1．句意：Beinao-1向他的腿部发送微小电信号。 根据“A man couldn’t stand up”以及“take some small steps”，可知该男子之前无法站立，后来能迈步，说明信号是发送到他的“腿部”。应选用legs。 2．句意：现在她可以再次和家人“交流”了。 根据“A woman had trouble speaking.”，可知她说话有困难，通过设备将想法转化为文字后，她能够再次和家人“交流”了。应选用talk。 3．句意：有了它，他们已经成功地帮助几位残疾人重新开始活动和说话。 根据前文列举的两个残疾人恢复部分能力的例子，可知科学家们已经“成功地”帮助了他们。应选用successfully。 4．句意：当它被放在大脑表面时，它接收信号并发送出去。 根据语境，“被放在大脑表面”是“接收并发送信号”的时间条件，应用When引导时间状语从句。 5．句意：有了这个“翻译器”，机器能理解大脑的想法并行动。 根据“a robotic arm can pick up a cup...”，可知机器在理解大脑想法后会采取具体的“行动”。应选用act。 6．句意：例如，如果一个残疾人心想“我想喝水”，机械臂可以拿起一个杯子，装满水，小心地将它送到这个人嘴边，最后再放回原处。 根据“fill it with water, lift it”，可知倒水和举起杯子之前，机械臂需要先“拿起”杯子。应选用pick up。 7．句意：通过这种方式，Beinao-1帮助残疾人用意念控制事物。 根据前文机械臂根据人的想法完成倒水喝水的一系列动作，可知这是残疾人用意念在“控制”事物。应选用control。 8．句意：这表明中国在高科技领域变得更加强大。 根据“Beinao-1 has broken the world record in its field.”，可知打破世界纪录表明中国在高科技方面变得更加“强大”。应选用powerful。 9．句意：科学家们正在努力让更多的残疾人更容易使用它。 根据语境，科学家努力改进技术的目的是为了方便残疾人，即让使用变得“更容易”；“make it easier for sb. to do sth.”为固定句型。应选用easier。 10．句意：他们希望它能给更多需要帮助的家庭带来希望。 根据语境，这项技术是为了帮助残疾人，因此是给“需要帮助的”家庭带来希望；“in need”是固定搭配，意为“需要帮助的；在困难中”。应选用need。 11．B 12．A 13．C 14．D 15．B 16．A 17．A 18．B 19．C 20．D 本文讲述发明家爱迪生从小爱提问爱尝试，历经上万次失败发明电灯，最终改变世界的故事，告诉我们成功需要付出努力、为梦想负责的道理。 11．句意：当他还是小男孩的时候，他“喜欢”提问和尝试新事物。 后文提到母亲一直鼓励他独立思考，说明他从小就爱提问尝试，应用loved“喜爱”。hated“讨厌”、forgot“忘记”、stopped“停止”都和他爱钻研的性格不符。 12．句意：为了做出电灯，他失败了成千上万次。 后文提到“他试了一种又一种材料，每次小灯很快就熄灭”，说明他反复失败，应用failed“失败”。rested“休息”、waited“等待”、played“玩耍”都和反复试验受挫的语境不符。 13．句意：但是他从不放弃。 固定搭配give up表示“放弃”，应用gave“给出”。got“得到”、put“放置”、took“带走”都和固定搭配逻辑不通。 14．句意：我没有失败，我只是找到了一万种“行不通”的方法。 前面提到试验的材料都不能让灯持续亮，也就是方法不起作用，应用work“起作用、奏效”。go“走”、come“来”、stay“停留”都和“方法有效”的含义不符。 15．句意：如今，电灯在全世界被使用。 主语the light bulb和use是被动关系，应用一般现在时被动语态used“被使用”。using“正在使用”、use“使用”、uses“使用（三单）”都不符合被动语态的语法要求。 16．句意：很难想象我们没有它的生活是什么样。 前文说电灯遍布全球，说明生活离不开电灯，应用without“没有”。with“带有”、for“为了”、by“通过”都和“难以想象没有电灯的生活”逻辑不符。 17．句意：爱迪生的故事告诉我们，伟大的想法只有通过努力才能变成现实。 固定搭配be turned into表示“被转变为”，应用turned“转变”。turning“正在转变”、turns“转变（三单）”、turn“转变（原形）”都不符合被动语态结构。 18．句意：没有哪种成功是可以轻松获得的。 主语success和achieve是被动关系，应用被动语态achieved“获得”。achieving“正在获得”、achieve“获得（原形）”、achieves“获得（三单）”都不符合被动语法。 19．句意：我们应该像爱迪生一样，对自己的梦想负责。 固定搭配be responsible for表示“对……负责”，应用responsible“负责的”。famous“著名的”、ready“准备好的”、sorry“抱歉的”都和“为自己梦想负责”的语境不符。 20．句意：只要有人敢于尝试，想法的力量会在未来持续改变我们的世界。 固定搭配keep doing sth表示“持续做某事”，应用changing“改变”。change“改变（原形）”、changed“改变（过去式）”、to change“改变（不定式）”都不符合keep的固定搭配要求。 21．A 22．B 23．B 24．C 25．A 26．A 27．C 28．C 29．B 30．D 本文主要讲述了无人机在铁路领域的应用前景，它们不仅能提高铁路的安全性、可靠性和准点率，还能降低成本并保护工人的安全。 21．句意：它们仅仅能被用来拍漂亮的照片吗？ 此处表示疑问，探讨无人机是否“仅仅”用于拍照，选only“仅仅”，符合句意。lonely孤独的”、alone、“单独、独自”、single“单一的”，都不符合。 22．句意：一小群无人机能让铁路变得安全，同时帮助铁路公司省钱吗？ 根据后文“确保铁路对列车来说是安全的”的提示，此处表达无人机可以让铁路更安全，选safe“安全的”，符合语境。clean“干净的”、lively“生动的”、attractive“有吸引力的”都不符合。 23．句意：无人机已经被用来检查电线了。 后文明确提到“它们也可以做同样的事来检查铁轨”，说明无人机已经被用来检查电线了，选check“检查 ”，符合句意。look是不及物动词，不能接宾语；watch侧重“观看动态事物”；set“设置”，都不符合。 24．句意：它们也能做同样的事情来检查铁路线和其他重要的东西，比如铁路的正确位置和转折点。 这里是在列举铁路的相关检查内容：比如铁路的正确位置和转弯点。选such as“比如”，用来列举多个事物，符合用法。for example后面常用逗号隔开；as for“至于”；as well as“以及”，都不符合此处举例的用法。 25．句意：它们被检查得越频繁，铁路的安全性、可靠性和准点率就会提高得越多。 本句是“the+比较级，the+比较级”句型，表示“越……，越……”。此处表示检查得越频繁，安全性提高得越多，选more often“更频繁地”，符合逻辑。more slowly“更慢地”、more quickly“更快地”、more suddenly“更突然地”都不符合。 26．句意：运营会更高效，成本也会降低。 结合前文检查更频繁、安全准点率提升，能推出操作会变得更高效，同时成本会削减。选efficient“高效的”，符合句意。recent“最近的”、narrow“狭窄的”、necessary“必要的”，都不符合。 27．句意：据说欧洲铁路仅此一项每年就花费约200亿欧元，因为他们经常派工人在晚上检查和修理铁路。 spend money on sth.“在某事上花费金钱”，是固定搭配，此处是指仅此一项每年就花费约200亿欧元，选spend“花费”，符合语境。speed“加速”、explore“探索”、boost“促进”，都不符合。 28．句意：如果没有无人机的帮助，那可能是一项危险的工作。 前文提到过去要派工人夜间检修，说明在没有无人机的帮助下，这份工作是很危险的，选without“没有”，符合逻辑。for“为了”、with“和……一起”、under“在……下面”，都不符合。 29．句意：通过使用最新的技术，无人机本身可以为铁路提供更高价值的服务，并在造成任何安全问题之前探索铁路中的错误。 此处是反身代词作同位语，指代复数名词drones，表示“无人机本身就可以为铁路提供更高价值的服务”，对应的反身代词是themselves“它们自己”。they“它们”，主格人称代词；it“它”；itself“它自己”，都不符合。 30．句意：凭借它们向前看的能力，它们能发现任何问题，以便快速行驶的列车能够及时作出反应。 根据后文“they can find any problem”可知，此处是指凭借它们向前看的能力，选ability“能力”，符合句意。address“地址”、account“账户/解释”、addition“附加物”，都不符合。 31．B 32．A 33．B 34．D 35．C 本文介绍了三位年轻发明家及其发明，核心结论是年轻人也能改变世界。 31．细节理解题。根据Louis Braille部分“Louis was born in a small town near Paris, France.”可知，Louis Braille来自法国。 32．细节理解题。根据Louis Braille部分“Blind people can read and write by touching the dots.”可知，这种带有六个凸点的特殊书写系统帮助的是盲人。 33．细节理解题。根据Anish Singh部分“It uses the sun to clean water.
