主题语境——网络 专项训练 训练1 　　　　　　　　　　　　　　　　　 Ⅰ 阅读理解 A Scientists at MIT have managed to change ordinary spinach (菠菜) plants into natural sensors which can find chemicals used in bombs. The secret to giving spinach the special power is nanotech (纳米技术), which is a scientific area that deals with making or changing things that are extremely tiny. “Ordinary spinach plants can be found everywhere and easy to store; like other plants, they normally take in carbon dioxide gas,” the scientists say. “But actually they can sense small changes of soil and water potential and respond to them. If we tap into this point, there is a wealth of information to access.” That’s what the scientists use to power their tiny experiments. For this experiment, the scientists placed two different kinds of tiny nano-materials into spinach plants. To get them into the plants, the scientists put a liquid containing them on the bottom of the plant’s leaves. As part of its natural process, the spinach plant pulls water through its roots and into its leaves. If the water contains certain chemicals used in bombs, the tiny sensors in the leaves make the nano-tubes, which, along with the sensors, were placed into the spinach plant before by the scientists, produce a slightly special kind of light. By watching the plant constantly using a camera attached to a cheap computer, the scientists set up a system that can send a warning e-mail if chemicals from explosives are found in the water. The computer the scientists used is about the size of a playing card. They say that in the future, their system could even use a cell-phone with its camera changed slightly. Discovering chemicals used in bombs is just one of the many uses the researchers are exploring. They have used such plants to discover several other dangerous chemicals as well. From their point of view, there’s no doubt that in the future, such systems could give farmers specific information about the health of the land and water on their farms. (　)1.Why do the scientists use spinach plants to do the experiment? A.They are common in the daily life. B.They are environmentally responsive. C.They absorb much carbon dioxide gas. D.They are small in size and easy to store. (　)2.What’s the function of the nano-tubes placed into spinach plants? A.To control the camera. B.To contain the liquid. C.To fix the tiny sensors. D.To give off plant light. (　)3.What can we say about the application of the experiment? A.It’s diverse. B.It’s unexpected. C.It’s limited. D.It’s cheap. (　)4.What’s the suitable title for the text? A.Spinach is sensitive to chemicals in bombs B.Spinach sends warning e-mails using nanotech C.Nanotech helps spinach grow healthily D.Nanotech protects spinach from danger B Feeling a hug from each other via the Internet may be a possibility in the near future. A research team led by City University of Hong Kong recently developed a wireless, soft e-skin that can both detect and deliver the sense of touch, and form a touch network allowing one-to-multiuser interaction. It offers great potential for improving the distance touch communication. While there are numerous devices in the market to simulate (模拟) the sense of touch in the virtual world, they provide only touch sensing or touch response. The uniqueness of the novel e-skin is that it can perform self-sensing and touch reproducing functions on the same interface. The e-skin is a 7cm×10cm, 4.2mm-thick device containing 16 flexible actuators (驱动器), a microcontroller unit, a Bluetooth module, and other electronics on a flexible circuit board. The actuator serves as the core part of the e-skin. Once the actuator is pressed and released by a force, a current is produced to provide electrical signals that are turned into digital signals by a converter (转换器) and then sent to another e-skin via Bluetooth. When the signals are received, a current is caused to reproduce the touch response on the receiver’s e-skin through mechanical vibration (振动). The process can be reversed to deliver vibrations from the receiver’s e-skin to the corresponding actuator of the sender’s. The e-skin can communicate with Bluetooth devices and send data through the Internet with smart phones and computers to perform long-distance touch, and to form a touch Internet of Things (IoT) system, where one-to-one and one-to-multiple touch delivery could be realized. Friends and family in different places could use it to “feel” each other. This form of touch overcomes the limitations of space and greatly reduces the sense of distance in human communication. Next, the research team will focus on practical applications for people with visual disability, who could wear the e-skin to gain remote directional guidance and read Braille messages. (　)5.What is the unique feature of the e-skin? A.It provides hugs for users. B.It builds a social network. C.It provides touch sensing and copying. D.It monitors the process of self-sensing. (　)6.What does the underlined word “reversed” mean? A.Started. B.Disturbed. C.Completed. D.Exchanged. (　)7.What can we learn about e-skin? A.It strengthens bonds across distance. B.Its converter vibrates when working. C.It sends electrical signals to receivers. D.Its system delivers touch with phones. (　)8.What would be the best title of the text? A.A signal-sending application B.An invention for the disabled C.A device for virtual interaction D.A long distance communication Ⅱ 阅读七选五 You’ve got mail…and it’s a postcard Paulo Magalhaes, a 34-year-old Portuguese computer engineer, loves to open his mailbox and find a brightly coloured picture of Rome’s Colosseum, or Africa’s Victoria Falls, or China’s Great Wall. 1.　　　  “I often send postcards to my family and friends,” he says to China Daily. “But you can imagine that after a while, you never receive as many as you send, and you realize that not everyone is into it.2.　　　　” Seeking other like-minded souls, however, Paulo started looking in a somewhat unlikely place: online. Many would say the Internet is a place for people who have given up on the traditional postal service, but Paulo’s hunch (直觉) paid off.  Today his hobby has developed into the website postcrossing.com, a social network that has grown to 575,217 registered users in 214 countries and regions since he started it 10 years ago. 3.　　　　 Running the website has almost turned into a full-time job.  Language is certainly a barrier for many people. For postcrossing to work worldwide, a common communication language is needed so that everyone can understand each other. As cool as it may be to receive a postcard written in Chinese, the concept doesn’t work if one doesn’t understand it. 4.　　　　 So a common language is required and in postcrossing that’s English since it’s widely spoken.  “Many people in China have limited exposure to English. 5.　　　　That said,we know of many postcrossing members,including Chinese,who have actually improved their English skills through their use of postcrossing,” Paulo says.  A.And that’s totally fine. B.That makes it extra hard to learn and practise it. C.He likes to think of sending postcards as a family-friendly hobby. D.Many love to make a connection with someone from across the world. E.On August 5, the number of postcards exchanged by members topped 31 million. F.Similarly, if you speak only Chinese, receiving a card in Swedish takes part of the fun away. G.In short, he loves postcards and the excitement of getting a hand-written note from someone far away.

We’re not allowed to call her Gran, because it makes her feel old. That summer, I lost my job and felt hopeless. One day, I visited her. She picked up a box. “There you go,” she said. “You are good at these things, aren’t you?” It was a new phone. Her current mobile was ancient. I was surprised it still worked. “Yes,”I said. “That’s why I ask you. Young people know more about such things than us oldies. You can take it home and get it all set up,” she went on. “Then, when you bring it back, you can show me how to use it, such as surfing the Internet, sending e-mails and so on.” She smiled so sweetly that I felt a surge of love for her. I grabbed the box. Setting up the phone would be easy. It was teaching her how to use it that may prove challenging. The following day I headed back to my great-grandmother’s with the phone. “Here’s your phone. All ready to use.” For the next hour, I was busy setting up her passcode and fingerprint recognition, which she said was like something out of James Bond. She chose a picture for her screen and it was all going so well until I tried to show her how to swipe the screen(滑动屏幕). “Swipe the screen?” she asked. She was 92, I reminded myself. This had been tiring for her. She pressed at the up arrow and got angry when nothing happened. When I finally got her to swipe the screen, she didn’t put the right amount of pressure on and the menu slipped away. After what seemed like hours, she threw the phone on the sofa. “Take it away!” she howled. “I want my old phone back!” I picked up the phone and was about to leave to give her time to cool down when I realized I didn’t want to go home when she was angry and upset. 注意:续写词数应为150个左右。 Paragraph 1: “Come on, Eileen. One more try,” I said.    Paragraph 2: Seeing this, I was not feeling hopeless any more.  答案 训练1 ⅠA 文章大意：本文是一篇说明文。文章主要介绍了麻省理工学院的科学家们使用纳米技术将菠菜变成了天然传感器,使其可以发现在炸弹中使用的化学物质,并发送警告电子邮件。 1.B　细节理解题。根据第二段“‘But actually they can sense small changes of soil and water potential and respond to them. If we tap into this point, there is a wealth of information to access.’ That’s what the scientists use to power their tiny experiments.”可知,科学家们使用菠菜做实验是因为它们可以感知环境的微小变化,并对其做出反应。故选B。 2.D　细节理解题。根据第三段“If the water contains certain chemicals used in bombs, the tiny sensors in the leaves make the nano-tubes, which, along with the sensors, were placed into the spinach plant before by the scientists, produce a slightly special kind of light.”可知,科学家将纳米管放入菠菜中,如果水中含有炸弹中使用的某些化学物质,纳米管就会发出特殊的光。故选D。 3.A　推理判断题。根据第四段“Discovering chemicals used in bombs is just one of the many uses the researchers are exploring. They have used such plants to discover several other dangerous chemicals as well. From their point of view, there’s no doubt that in the future, such systems could give farmers specific information about the health of the land and water on their farms.”(发现炸弹中使用的化学物质只是研究人员正在探索的众多用途之一。他们还利用这些植物发现了其他几种危险的化学物质。从他们的角度来看,毫无疑问,在未来,这样的系统可以为农民提供有关农场土地和水的健康状况的具体信息。)可知,这一实验可应用的范围非常广,是多种多样的。故选A。 4.B　主旨大意题。根据第一段“Scientists at MIT have managed to change ordinary spinach(菠菜) plants into natural sensors which can find chemicals used in bombs.”以及第三段“By watching the plant constantly using a camera attached to a cheap computer, the scientists set up a system that can send a warning e-mail if chemicals from explosives are found in the water.”可知,本文主要介绍了科学家使用纳米技术将菠菜变成了天然传感器,使其可以发现在炸弹中使用的化学物质,并发送警告电子邮件,所以B项可以作为文章标题。故选B。 B 文章大意：这是一篇说明文。本文主要介绍了一种可以让人们通过互联网感受“拥抱”的电子皮肤。 5.C　细节理解题。根据第二段的“The uniqueness of the novel e-skin is that it can perform self-sensing and touch reproducing functions on the same interface.”(这种新型电子皮肤的独特之处在于它可以在同一界面上实现自我感知和触感再现功能。)可知,这种电子皮肤的独特之处是提供并复制触感。故选C。 6.D　词义猜测题。根据画线词上文“When the signals are received, a current is caused to reproduce the touch response on the receiver’s e-skin through mechanical vibration (振动).”(当接收到信号时,会产生电流,通过机械振动在接收者的电子皮肤上重现触摸反应。)和下文“…deliver vibrations from the receiver’s e-skin to the corresponding actuator of the sender’s.”(……将振动从接收者的电子皮肤传递到发送者的相应驱动器。)可知,机械振动可以让接收者感受触摸,也将接收者由此产生的振动发送给相应的驱动器。由此可知,这个过程是可以互换的。由此猜测画线词意为“互换”,与exchanged同义。故选D。 7.A　细节理解题。根据第四段的“Friends and family in different places could use it to ‘feel’ each other. This form of touch overcomes the limitations of space and greatly reduces the sense of distance in human communication.”(不同地方的朋友和家人可以用它来“感受”彼此。这种形式的触摸克服了空间的限制,大大减少了人类交流中的距离感。)可知,这种电子皮肤减少了人们交流中的距离感,即它可以加强跨距离的联系。故选A。 8.C　主旨大意题。通读全文,并结合第一段(在不久的将来,通过互联网感受彼此的拥抱可能是可能的。由香港城市大学领导的一个研究团队最近开发了一种无线、柔软的电子皮肤,它可以检测和传递触觉,并形成允许一对多用户交互的触觉网络。它为改善远程触摸交流提供了巨大的可能性。)可知,本文主要介绍了一种可以让人们通过互联网感受“拥抱”的电子皮肤,它通过提供和传递触感来减少人们交流中的距离感,加强跨距离的联系。因此C项(一个用于虚拟互动的设备)可以作为本文的最佳标题。故选C。 Ⅱ文章大意：本文是一篇新闻报道,主要介绍了Paulo Magalhaes创办了一个网站,并鼓励人们在网上分享和交换明信片。 1.G　根据上文“…Rome’s Colosseum, or Africa’s Victoria Falls…”可知,Paulo非常喜欢收到印有各地风景名胜的明信片,而G项就是对上文的总结与概括。故选G项。 2.A　根据上文“I often send postcards to…you never receive as many as you send…not everyone is into it.”可知,Paulo经常给朋友们送明信片,但并不是所有人都喜欢。同时下文又提到“Seeking other like-minded souls, however…”故可推断,虽然并不是所有人都喜欢明信片,但Paulo还是努力寻找志同道合的人,故A项能起到衔接上下文的作用。 3.E　结合上文“…grown to 575,217 registered users in 214 countries…10 years ago.”可知,此处说明该网站的注册用户很多,同时E项说明这些成员交换明信片的数量已经达到了3100万张。由此可知E项承接上文,故选E项。 4.F　根据上文“Language is certainly a barrier…”和下文“So a common language is required…”可知,该段主要讲述了明信片交换中遇到的语言障碍,即如果不懂当地的语言,可能没有办法很好地理解和欣赏明信片上的内容的意义。F项是对上文这种现象的举例描述,因此答案选F项。 5.B　根据上文“…have limited exposure to English.”和下文“That said, we know of many…improved their English…”可知,很多中国人对英语接触有限,这使得他们学习和练习英语非常困难,但通过交换明信片的方式,他们很多人逐渐提升了英语能力。B项承上启下,故选B。 ⅢOne possible version: With the increasing popularity of Internet slang among teenagers, our school has carried out a survey. The results are as follows. Some students are in favour of it while some are opposed. 35% of students feel it vivid and fashionable to say Internet slang. And 33% of students think it is full of humour and wisdom. A quarter of students hold the opinion that it is more convenient to use Internet slang when they chat online. 7% of students view it as a simple thing. They think Internet slang isn’t accepted by most people and that if used too often, it will cause misunderstanding. As far as I am concerned, Internet slang is a double-edged sword. Provided that we use it in a proper way, our online communication will be more colourful. 训练2 Ⅰ文章大意：本文是一篇记叙文。文章讲述了作者通过Pilots N Paws网站帮助一家正在搬家的人将他们的狗接到另一个城市的过程。作者最终和另一位飞行员一起成功地将这只狗带回到“她”的主人身边。 1.B　根据空后“They could not afford to pay for…for their dog, Tiffy…”可知,这家人负担不起运送他们的狗Tiffy的费用。由此可推知,他们的经济预算很紧张。turn转变; budget预算; schedule时间表; connection联系。故选B项。 2.D　根据前文“They had to move to Virginia…”可知,他们要搬到弗吉尼亚州,但负担不起狗的运输费用。food食物; shelter庇护处; medicine药品; transportation运输。故选D项。 3.A　根据前文“…I saw a post on the PNP(Pilots N Paws)website from a family in Topeka.”可知,这一家人要搬到弗吉尼亚州,负担不起狗的运输费用,但极其想带上Tiffy,因此上网发帖求助。desperately极度地; temporarily暂时地; secretly秘密地; originally最初地。故选A项。 4.C　根据空后“…I was planning another PNP flight…”可知,作者碰巧计划与另一位飞行员一起执行PNP的飞行任务。It happens/happened that…意为“碰巧……,恰好……”。appear似乎,出现; prove证明; happen碰巧,恰好; show显示。故选C项。 5.B　另一个飞行员Karen主动提出把Tiffy从堪萨斯城带到弗吉尼亚州。wait等待; offer主动提出; hurry匆忙; fail失败。故选B项。 6.D　根据前文from a family in Topeka可知,这家人和小狗在Topeka,因此作者的任务是去Topeka接上Tiffy。see off为……送行; look for寻找; hand over移交; pick up接载。故选D项。 7.B　根据空后“George, the husband, was trying to be calm…”可知,作者见到狗的主人时,他们非常紧张。confused困惑的; nervous紧张的; annoyed恼怒的; curious好奇的。故选B项。 8.A　根据语境可知,对于乔治来说,将他的狗交给陌生人并相信一切都会进展顺利是很难的。hard艰难的; fine不错的; common普通的; lucky幸运的。故选A项。 9.C　根据前文可知,作者并不认识这一家人,因此作者对这 家人来说是一个陌生人。coworker同事; passenger乘客; stranger陌生人; neighbour邻居。故选C项。 10.B　根据语境可知,对乔治来说,相信一切都会进展顺利是艰难的。 speed up加快速度; work out进展顺利; come back返回; take off起飞。故选B项。 11.D　根据后文“…Tiffy into the plane.”可知,作者请求乔治和他的妻子帮助自己将Tiffy装进飞机。feed喂养; follow跟随; change改变; load装进。故选D项。 12.A　根据常识可知,将狗运到弗吉尼亚州后,作者会打电话给他们。call打电话; join参加; leave离开; serve服务。故选A项。 13.D　根据空后“…and Tiffy was a great passenger.”可知,这次飞行很顺利,Tiffy表现得也很好。unnecessary不必要的; unexpected意外的; unavoidable不可避免的; uneventful平静无事的。故选D项。 14.C　根据前文another pilot, Karen可知,Karen是个飞行员。因此可推知,第二天,Tiffy和Karen一起飞行。return返回; fight打斗; fly飞行; agree同意。故选C项。 15.A　根据空后“…sent me a nice e-mail with pictures.”可知,乔治对“我”非常感激。thankful感激的; generous慷慨的; proud骄傲的; sympathetic表示同情的。故选A项。 Ⅱ文章大意：这是一篇新闻报道。 文章讲述了现在中国互联网发展的现状,中国农村互联网用户的数量增加,电子商务直播蓬勃发展,为中国的反贫困目标做出重大贡献。 1.accounting　考查非谓语动词。本句已有谓语had且无连词,account用非谓语形式,与逻辑主语about 285 million Internet users是主动关系,account应用现在分词形式。故填accounting。 2.has grown　考查动词时态和主谓一致。结合时间状语in the last few months可知,谓语动词grow用现在完成时,“the number of+名词复数”(……的数量)作主语,谓语应用单数形式。故填has grown。 3.greater　考查形容词比较级。结合than ever可知,应用形容词比较级greater作定语,修饰名词role。故填greater。 4.recognition　考查名词。设空处为名词作with的宾语,表示“认可”,故填recognition。 5.that　考查宾语从句。设空处引导宾语从句,从句中不缺少成分,应用that连接。当主句中的动词后接两个由that引导的宾语从句时,第二个宾语从句的连接词that不可以省略,故填that。 6.increasingly　考查副词。修饰后文形容词active,应用副词increasingly,作状语。故填increasingly。 7.activities　考查名词复数。根据over 10 million可知,应用可数名词activity的复数形式。故填activities。 8.to　考查介词。contribute to意为“有助于……,促成……”,符合题意。故填to。 9.the　考查冠词。此处为“the+形容词”表示一类人, 此处表示“贫困人口”,应用the poor。故填the。 10.to access　考查非谓语动词。短语allow sb to do sth表示“使某人能做某事”。故填to access。 Ⅲ 详解 1.段落续写: ①由第一段首句内容“‘来吧,艾琳。再试一次,’我说。”可知,第一段可描写作者如何鼓励曾祖母,曾祖母最终学会使用新手机以及曾祖母的反应。 ②由第二段首句内容“看到这,我不再感到绝望了。”可知,第二段可描写作者从曾祖母学习使用新手机的故事中得到启发。 2.续写线索:作者鼓励曾祖母—曾祖母终于学会使用新手机—曾祖母很高兴并感谢作者—作者被曾祖母感染—作者相信只要有耐心就能找到新工作—作者的感悟 One possible version: “Come on, Eileen. One more try,” I said. “No,” Eileen insisted, “I just want my old phone back!”, going to bring back her old device (现在分词短语作状语). Gathering my patience (现在分词短语作状语), I stepped forward, hugged my gran and gently explained that the old phone, just like an antique, was incapable of providing Internet access or sending e-mails. “Please let go of the old one, and embrace the brand-new world,” I encouraged her. Empowered by my words(过去分词短语作状语), she found the courage to give it one more shot(不定式短语作定语). Smoothly and magically, through the fingerprint recognition, this time, she swiped the screen with the right amount of pressure and located the e-mail app on the menu. Seeing this(现在分词短语作状语), I was not feeling hopeless any more. More surprisingly, a newly received e-mail blew me away, it reading (独立主格结构)“Please let go of the old job, and just embrace another new opportunity.” The knowing giggles from my wise great-grandmother confirmed what I already knew deep down(what引导宾语从句). The familiar yet powerful words lifted the weight from my shoulders, motivating me to seek out a better career(现在分词短语作状语). How wise and strong my gran was!(感叹句) The words kept echoing in my mind ever since. Even now, I am constantly reminded of the transformative experience, where I got the lesson(where引导非限制性定语从句)—Out with the old, in with the new! 学科网（北京）股份有限公司 $
