-------------------------天才是百分之一的灵感加百分之九十九的勤奋------------------------------ 金戈铁骑 Unit 3 Computers learning about language课时作业 Ⅰ.阅读理解 A “Smile！” I shouted, holding a yellow sign up on a busy street in Seattle. We were three thousand miles away from home on a Random Acts of Kindness and Volunteerism Road Trip. We had two aims. One was to try out our new “Smile！” signs and see how much kindness and joy we could spread in Pike Place Market. The other was to raise $80 by doing street performances, enough for gas to Portland and a small hotel room. We weren't sure how people would react (回应) to our signs. I nervously raised up our signs and shouted, “Hi, there！” to a young couple. They looked over and felt confused. Then they read our signs and broke into a smile. Before long, some tourists wanted to take a photo with us and some strangers stopped to ask us about our signs. In fact, we paid so close attention to our “Smile！” project that we forgot the other aim. Before we knew it, the sun was setting, and we had no money for our trip to Portland. We sat down to watch a blind musician play the guitar while thinking about what to do. He was packing up when a passing crowd kicked down his change bowl. He stumbled (绊倒) into the crowd. We rushed to help him, but another man moved more quickly to help him. Once the musician had his money safely returned, we ran over to meet the strange helper and said, “We just wanted to praise you for your good deed.” He smiled, looking at our signs. “Your trip reminds me of something similar I once did when I was young，” he said. “Look! I'd like to donate (捐赠)．” We told him, “No, thanks! We are fine. We've collected plenty of money.” We lied. “Please let me donate. It will make me feel like I'm a part of this adventure，” he insisted. And then the stranger opened his wallet and pulled out four $20 bills. The money was exactly what we had intended to raise that day. We were astonished. It seemed as if he had known somehow. 【语篇解读】 本文是一篇记叙文。作者一行人在志愿者旅行活动中用“微笑！”标牌来传播善意和快乐。 1．What's the main purpose of the road trip? -------------------------天才是百分之一的灵感加百分之九十九的勤奋------------------------------ 金戈铁骑 A．To spread kindness and joy.

It's a good alternative (替代物) to boarding your dog at a dog boarding kennel (狗舍) or your neighbour's house. The way Rover works is sort of like Airbnb. Dog owners browse the “search” section of the site or app for pet sitters, which can be organized by zip code and available dates. Information of pet sitters is provided, complete with many reviews, specific services and rates. Now Rover has over 25,000 pet sitters in more than 5,000 US cities. And they're all experienced pet sitters. After finding someone that meets your needs, just send messages to the pet sitter to arrange a meeting. Then, like Rover says, all that is left to do is relax! Rover's pet sitters are encouraged to send text and picture information throughout the day, and if there's a medical emergency, the site will send a vet. Besides, don't worry about a pet sitter who falls through, because someone else will soon take his or her place. Happy doggie, happy travels — that sounds good to us.

AKrakatau Volcano (喀拉喀托火山)is on a small island in Indonesia. It had been peaceful for about 200 years before it erupted (爆发)in 1883.The first signs of the activity of the volcano appeared in May 1883, when fire and smoke could be seen at the top of the mountain. Great noise could be heard even in Jakarta, a hundred miles away. Later the activity grew much greater. The peak (山顶)was covered with smoke and fire; the smoke at one time was seventeen miles high in the air. The lava—soft and hot rock—shot up into the air and rolled down the sides of the mountain.The mouth of the volcano was not at the peak of the mountain but on its side, close to the sea. As it grew bigger and bigger with the eruption, the sea water got into it. When the sea water reached the lava inside the volcano, it made the upper part of the lava colder and harder. And this sealed off(封住)the rest of the lava below. As the inside of the lava could not break through the seal, the pressure (压力)built up until the mountain blew up.The eruption of the volcano was followed by several earthquakes which brought about bad results. About 36, 000 people were killed and many towns and villages near the sea were completely destroyed by the great waves which the earthquakes caused.1. Give the correct order of the course of volcano eruption.①The peak was covered with smoke and fire.②Fire and smoke could be seen at the top of the mountain.③Great noise could be heard a hundred miles away.④The lava shot up into the air and rolled down the sides of the mountain.A. ①②③④B. ①③②④C. ②③①④D. ④①③②答案:C解析:细节理解题。
人教版高中英语必修二Unit3Computers Language points精编课时作业(2)
Unit 3 Computers Language points课时作业一、阅读理解Sarah Lynn，an educational consultant and teacher，thinks English learners can improve their ability to remember and use new words by testing themselves. She adds that self-testing improves retrieval (数据检索)—the ability to use and remember new words.If you are like most learners，you may have faced such a situation：You think you understand a topic. Yet when asked to use what you have learned，you are not able to remember the information. Not being able to retrieve new ideas could happen on a test or even in a conversation.Learning takes effort. It takes effort because the learning process changes the brain，says Sarah Lynn. One way it changes the brain is by creating connections，which are called dendrites (树突).Lynn suggests that dendrite connections are important for retrieval. There are three main ideas about how to grow dendrites and improve retrieval，making connections，using repetition and testing yourself.Lynn is not the only expert who recommends self-testing. A paper in Journal of Applied Research in Memory and Cognition says one benefit of testing practice is that it improves retrieval. Retrieving information once makes retrieving that information easier in the future. In addition，the paper says，when students test themselves as part of studying，they learn what they do not know. When students know what they do not understand，they can pay attention to overcoming their weaknesses. Lynn recommends that learners test themselves by getting away from what they are studying. Then，they should test themselves by thinking about what they have learned. She recommends that learners make themselves write or speak something. Lynn suggests reading something or watching a video on the topic，then getting rid of the reading or audio material and summarizing it. This will allow learners to test what they know.The benefits of such practice，Lynn says，are not just about improving your ability to remember information. By testing yourself，you can build confidence in the skills youhave developed. When you test yourself，Lynn says，you will see how much progress you have made. This progress will satisfy and encourage you to do more in the future. Next time you are studying English，try to test yourself. A simple way to test vocabulary is to create flashcards with clues on one side and the answer on the back. Another way is to use online services to create digital flashcards，through which learners can do a variety of activities based on one set of new words or information. You can match words with meanings，write a word after looking at a picture，or listen to a word and write it. You can also play games with the new words and meanings. Another way is to ask yourself questions at the end of the day，at the end of a study session，or at other times. Lynn recommends that learners ask themselves questions such as，“What did I learn today? What were those words that I thought were interesting? What was that verb tense I learned? How does it work？”The important point is this: Effective__learning__takes__time，effort__and__practice. Do not just assume that you can read something once or twice and fully understand it. Even if you highlight important points or take notes in a class，you probably do not fully understand what you learned. After all，Olympic athletes cannot learn how to swim or run just from reading a book. They have to practice swimming or running every day for years. They often compete in races to test their skills. Like those athletes，successful language learners practice as much as they can，and test themselves to improve their skills.Self-testing is one way to improve your retrieval and inform your future course of study. Give it a try，and let us know how it works for you.【语篇解读】本文是一篇说明文。

2019_2020年人教版必修二Unit 3 Computers language points 课时作业（2）1 / 8Unit 3 Computers language points 课时作业（本卷满分100分）一、阅读理解（每小题2分，共16分）AWho is smarter? A human being or artificial intelligence(人工智能)?The question swept the world when a Google-developed program called AlphaGo defeated the world top player, South Korean Lee Se-del, 4-1.So, what comes next?Some people have been arguing that artificial intelligence, or AI in short, will be a bad thing for humans. In an interview with the BBC in 2014, UK scientist Stephen Hawking warned that “the development of full artifici al intelligence could mean the end of the human race.”So are we really about to live in the world shown in the Terminator movies? “Not quite ,” answered The Economist . After all, it’s not hard to get a computer program to remember and produce facts. What is hard is getting computers to use their knowledge in everyday situations.“We think that , for the human being, things like sight and balance(视觉平衡), are natural and ordinary in our life.” Thomas Edison ，founder of Motion Figures, a company that is bringing AI to boys, told the newspaper. “But for a robot , to walk up and down just like human beings requires various decisions to be made every second, and it’s really difficult to do.”As The Economist put it, “We have a long way to go before AI can truly begin to be similar to the human brain, even though the technology can be great.”Meanwhile, John Markoff of The New York Times said that researchers should build artificial intelligence to make people more effective.“Our fate is in our own hands,” he wrote. “S ince technology depends on the values ofits creators, we can make human choices that use technology to improve the world.”1. What was the result of the match? A. Lee Se-del won AlphaGo 4-1. B. Lee Se-del was defeated. C. Google program beat AlphaGo.D. Neither side won the match.2. What does Thomas Edison possibly mean in his remarks? A. It’s very hard for AI to beat the human brain. B. AI would take the place of human beings. C. AI can make various decisions quickly. D. AI does better than humans in sight and balance.3. Who believes much has to be done to improve AI? A. Stephen Hawking. B. John Markoff. C. The New York Times .D. The Economist .4. What does the underlined part in the last paragraph imply? A. AI will improve the world completely. B. AI is in the control of human beings. C. AI may bring disasters to human beings. D. AI will make our future out of control.BAs life in cities worldwide becomes more expensive, urban designers are using modern technology to help citizens avoid traffic jams, and shorten the time needed for bus waiting and other things. Technology is also used to cut costly waste.In Santander, a Spanish port city, parking is easy to find. As one car drives away, an underground sensor shows that a parking space is now free. 400 sensors send messages to signs on streets, and GPS devices direct drivers to the nearest available parking spaces, reducing traffic jams. Trash is collected only when the bins are full and bus stop signs show exactly when the next bus is coming. The public parks are watered only the soil gets dry. All this is made possible by 20,000 sensors installed on buildings, street posts andeven buses. They are part of the “smart city” project, launched by the University of Cantabria seven years ago.University researchers like Luis Munoz regularly meet with locals to discuss how to make their city even smarter. “They propose when they have ideas and sometimes even develop by themselves. Here, we give them the opportunity to see these ideas happen in real life,” said M unoz. For example, the university helped a woman create an app that outlines the easiest route for walking with a baby stroller. Another provides information to residents about their water consumption and sends an alarm to their phone if there is a leak.The Santander smart project is attracting the attention of larger cities in Europe and elsewhere that are looking for smart solutions to urban problems.5. What is the life like in Santander?A. It is meaningful.B. It is full of freedom.C. It is likely to change fast.D. It is effective and convenient.6. How can residents help Munoz’s job?A. By offering some original or fresh ideas.B. By showing him around the city.C. By installing sensors themselves.D. By using as little water as possible.7. What do es the underlined word “Another” in Paragraph 3 refer to?A. A university.B. A phone.C. An easy route.D. An app.8. What can be the best title for the text?A. A Worldwide ProblemB. A Smart City ProjectC. A Creative ResearcherD. A Trend in Urban Design二、七选五（每小题2分，共10分）There have been a lot of comments recently surrounding 5G, the next generation of wireless technology. 9. ? How might it change our lives?5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity (容量). 10. . It is expected to permit more users to do more things at a faster rate.However, technology experts say there is a major way that 5G is different from the earlier systems. 11. . It will affect many more devices and industries than other “G” versions.5G will help fuel future “smart cities” by connecting sensor networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality(虚拟现实). Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.12. . The increased data flow across 5G networks would give Internet attackersa lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety. 13. , or a network breakdown could cause self-driving vehicles to crash.A. Why is 5G so popularB. What is this technologyC. Every coin has two sidesD. The new 5G system promises more of the sameE. It will move beyond mobile network technologyF. A breakdown of 5G networks may cause economic lossesG. A failure during a doctor’s remote operation cou ld lead to death2019_2020年人教版必修二Unit 3 Computers language points 课时作业（2）3 / 8三、完形填空（每小题1.5分，共30分）Crowdsourcing is an interesting new application of the saying “Many hands make light work”. In the same way that classmates might work 14 on a task, now dozens, hundreds or thousands of people can collaborate(合作) on projects that would be too ___15 or complex for a small group of co-workers. At the same time, crowdsourcing follows the old 16 that two heads are better than one. When many people collaborate, they not only work faster, but they also work better, by 17 their intelligence and experience.Perhaps one of the most 18 examples of crowdsourcing is Wikipedia — an online encyclopedia(百科全书) that is 19 , edited and managed by people all over the world. The writers are volunteers who 20 their work for free. And 21__ them, Wikipedia now offers more than 4 million free articles in English, and millions more in almost 300 other 22 . That’s an amazing achievement for a project that ___23 started in 2001.Traditional institutions, suc h as London’s Tate Museum, have also 24__ Crowdsourcing for projects. In 2010, the museum 25 the Tate Movie Project website, where children learned how 26 are made. The children also wrote stories, drew their own characters and 27 them to the website. After that, professionals worked with the children to 28 a collaborative film which was later shown on BBC television.Finally, crowdsourcing can also be a way for people and companies to make ___29 . Some businesses organize crowdsourcing websites to get suggestions for new products, services or advertising campaigns. They may also offer 30 for the best ideas. 31 , the Goldcorp mining company offered a prize for a list of good locations for discovering gold. The 32 list won $676, 000 and the company 33__ $3 billion dollars of gold.14. A. lateB. togetherC. wellD. again 15. A. similar B. personal C. large D. necessary 16.
