一轮复习阅读材料Unit20 New Frontiers阅读下列文章，完成阅读任务AIn the future, the Internet will be different from what it is now. There will be many more websites. It is predicted that in the year 2100, there will be hundreds of billions of websites. This means that the use of search engines will become much 1 (importance). And there will also be many more sites in different languages. This means that on every proper website, therewill be 2 (link) with the language you want.Another prediction on the Internet is 3 data transmission (传输) speed will increase 4 (global). According to Akamai Technologies, the average global data transmission speed in late 2009 5 (be) 1.7 megabits per second. Compare that to the record for data transmission speed set by Bell Labs：100 billion megabits per second. 6 that speed, you could transmit 400 DVDs worth of data every second. That's 7 enormous gap between what's currently possible and what's commercially available. But as time 8 (pass) , the costs of producing super-high-speed networks will decrease.In the future, people will live under the sea and the housing shortage will 9 (solve). There will be lots of glass domes (穹状建筑物) under the sea, 10 allow people to look all around into the sea. Air will be provided via air pipes which lead to the open air. You can travel from one dome to another via a kind of submarine which will also be made of glass. The domes will be so beautiful and the view under the sea will be so impressive that many people will prefer to live under water, and less people will prefer to live on land. This will have a positive effect on the environment on land.In the future we won't use oil or gas as energy any more. We will make use of sunlight, water and wind. Cars will run on water. Just fill your tank with water, and you can drive further than you could drive with the same amount of gasoline. Also, the exhaust won't be damaging to the environment, because it'll just be water vapor. So the water cycle won't change, we'll keep the same amount of water on the earth, and we won't run out of water. Also, all energy will be supplied by natural sources: sunlight, wind and water.Task1: Fill in the blanksTask2：Summarize the main idea of the passage.Task3: Choose the best answers1．What can we know about the Internet in the future from the first two paragraphs?A．It will be more important to use search engines.B．Most of the websites will be designed in English.C．People not knowing a foreign language will find it hard to surf the Internet.D．The gaps between developed countries and developing countries in Internet usage will be great 2．Why are super-high-speed networks not available to the public at present?A．Because the cost is too high. B．Because there are technical difficulties. C．Because Bell Labs doesn't want to sell its technique.D．Because governments haven't recognized their value.3．The underlined word “exhaust”in Paragraph 4 probably refers to “________”．A．oil product B．waste air C．solar energy D．wind energy 4．What can we infer from the text?A．The Internet is the most advanced invention in history.B．Water will run out sooner than we have expected.C．Houses under the sea will be made from metal.D．Sunlight, wind and water will benefit people more in the future.BWould you like to live in a city where buildings turn the lights off for you, where self-driving cars find the nearest parking space, and where even the rubbish bins know when they're full?Although it might sound like science fiction, living in a “smart” city like this could happen sooner than you think.Towns we have lived in for centuries are being upgraded，while completely new cities arebeing built.One such place is Songdo in South Korea. Every home there will have a built-in “telepresence” system－allowing users to control the heating and locks; take part in video conferences；and receive education, healthcare and government services.Around the city, escalators(自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the network.The digital mastermind(策划者) behind Songdo is the company Cisco. Indeed, technology firms around the world such as IBM, Siemens and Microsoft are already selling software to solve a range of city problems, from water leaks and air pollution to traffic jams. For example, IBM is gathering traffic data in Singapore which it uses to predict where traffic jams will occur—an hour before they happen.So what is all this smart technology for? Many hope all this connectedness will make cities greener, more sustainable(可持续的), and more efficient.And with 75% of the world's population predicted to live in cities by 2050, the transport system and emergency services will need to modernise to cope with all the new arrivals.But making cities smarter is only part of the solution，according to Dan Hill, chief executive(主管)of research firm Fabrica. He said，“We don't make cities to be efficient, we make cities for culture, commerce, community—all of which are very inefficient.”In the rush in order to make cities perform better, we could be missing their greatest asset(财富). “It is going to be smart citizens that make smart cities，”He said.Task1: Give a title to the passage:Task2: Choose the best answers1．Which of the following is TRUE of smart cities?A．They are unrealistic science fiction. B．They are already being built.C．They need to be upgraded at present. D．They are not suitable to live in.2．Citizens of Songdo will use their “telepresence” systems to do the following EXCEPT ________.A．control heating system B．attend teleconferencesC．recycle water efficiently D．receive government services3．IBM has designed a software in Singapore to ________.A．forecast weather condition B．solve air pollutionC．protect water resources D．predict traffic jams4．What will happen halfway through the 21st century?A．3/4 of the world's population are expected to live in cities.B．All the cities will be greener and more efficient.C．The present transport system remains to be well operated.D．Emergency services will be completely modernised.CAs a design student in Detroit，Veronika Scott was worried about the increasing numbers of homeless people suffering deeply during the cold winters.At the age of 21，she created The Detroit Empowerment Plan not to solve homelessness，but to provide much-needed warmth to the city's 20,000 street homeless people by designing a sleeping-bag coat.It is self-heated，waterproof(防水的)，and transforms into a sleeping bag at night.It's made by a group of homeless women who are paid，fed and housed while creating these coats made for those living on the streets.The focus is on the humanitarian system to create jobs for those that desire them and coats for those that need them at no cost.The goal is to employ，educate，and instill (灌输)pride.The importance is not with the product but with the people.Veronika Scott is a product design student at the College for Creative Studies.When she was working in studio class，a humanitarian group came in to sponsor the studio.They said“to design to fill a need”．Detroit has a pretty large number of people，about 20,000 living on the streets.She spent three days a week，every week，for five months working in a homeless shelter.The people there became part of the entire design.When the term ended，the project did not.She continued the project not just because she was crazy about it but because actually people needed it.She realized she had to take it to the next level and make it a system.On the beginning the empowerment plan was total about the coat. She could produce somecoats by her but she really wanted to reach out to people who need jobs. Now the importance of the project lies not within the product，and but within the people who are involved and affecting by the system. Thus it is one way to break the homeless cycle by giving homeless woman jobs while in the shelter. In this way they can earn money and find a place to live . More important, they can gain back their independent for themselves and their loved one .Task1: Find the ten mistakes in the last paragraph.Task2: Choose the best answers1．Veronika Scott's sleeping-bag coat ________.A．is very expensive B．has many functionsC．is mainly used at night D．is made by some students2．What first drove Veronika Scott to create The Detroit Empowerment Plan?A．Her studio class. B．The visiting group.C．Her college teachers. D．The homeless people.3．People CANNOT get ________ through the empowerment plan.A．clothing to wear B．houses to live inC．family to feed D．jobs for independenceTask3: What’s the main idea of the passage?DQuicker and faster 3-D printers have allowed not just amazing objects to be created, but have started to affect how doctors treat patients.We've put together a list of some of the most amazing medical breakthroughs made possible with 3-D printing.Life-Saving AirwayIn 2013, doctors created a new airway for Kaiba Gionfriddo, a boy born with an airway that kept collapsing (萎陷). To save his life doctors printed tiny tubes to join together in different shapes and sizes until one finally worked for Kaiba. It was placed in Kaiba's bronchus (支气管) so that it no longer collapsed. Even more remarkably, once the plant was placed it could stay there. It's designed to eventually be absorbed into the body.New “Bionic” HandsOne of the most remarkable ways 3-D printing is now being used is as a way to create prosthetics (假肢). A boy born without an arm named Alex was able to get a new “bionic” hand thanks to it. Last year a college student spent 8 weeks coming up with a special prosthetic design that only cost a few hundred dollars in materials. He said he wanted to create a prosthetic far cheaper than other choices that can run tens of thousands of dollars.A Practice HeartIn Seattle, doctors have been able to use 3-D printing technology to “practice” risky operations so that they will face fewer surprises in the operating room. Kami Sutton was born with her heart “in the wrong place”. For a recent operation her doctor was able to take many scans of Sutton's heart and print out a model. “Kami's heart is truly one-of-a-kind，” Dr. Stephan Seslar, a heart disease specialist said. “Operating on her without understanding the structure of her heart better could be very dangerous.”A New SkullA U．K. man was able to have part of his skull rebuilt thanks to a 3-D printer. Stephen Power broke his cheek bones in a crash. To help Power his doctors instead created 3-D bones all carefully printed in the shape of his face. “This is really the first time we've taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly，” said Adrian Sugar, a doctor.Task1: What kind of writing is the passage?

B．He thinks highly of it.C．It needs to be better planned. D．It functions well but needs improving.EPupils don't often think their teachers really exist outside the school gates; now robot classroom assistants could make this a reality. Almost 30 egg-shaped robots have started teaching English at primary schools in South Korea.The 3.3-foot-high machines have a TV panel (仪表盘), which displays a female face, and can wheel around the classroom while speaking to the students. The robots are also able to read books and dance to music, moving their heads and arms. But despite appearances, the robots are not autonomous beings. They are actually controlled remotely by English teachers living in the Philippines, who can see and hear the children by a remote control system. Cameras then detect the teachers' facial expressions and reflect them on the panel face.Apart from reading books, the robots use pre-programmed software to sing songs and play alphabet games with the children. The kids seem to love them since the robots look cute and interesting. Some adults also express interest, saying they may feel less nervous talking to robots than to a real person.The robots are still being tested. But officials might consider hiring them full time, if scientists upgrade them and make them easier to handle and more affordable. “Having robots in the classroom makes the students more active in class, especially shy ones afraid of speaking out to human teachers，” said Education official Kim Mi-Young.Some may be sent to remote rural areas of South Korea avoided by foreign English teachers. The robots, which cost ￡5,600 each, will provide extra support for teachers, but not replace them. Ms Mi-Young added, “Well-educated, experienced Filipino teachers are far cheaper than any teachers elsewhere, including South Korea. But robot teachers won't complain about health insurance, sick leave and severance package (遣散费), or leave in three months for a better-paying job in Japan ... All you need is a repair and upgrade every once in a while.”Task1: Give a title to the passageTask2: Choose the best answres1．What is the main idea of the passage?A．The most advanced robots go public.
