课时作业(十一)Unit 3ComputersSection ⅢLearning about Language & Using LanguageⅠ.单句语法填空1．I wish to work in my own________(personally) company in the future.2．If the opportunity________(arise)，I’d love to go abroad for further study.3．In many people’s opinion，that company，though relatively small，is pleasant________(deal) with.4．—I think he is taking an active part in social work.—I agree with you________a way.5．Professor Smith is so busy with the research________ he has no time left for any other activity.6．With more and more forests ________(destroy)，many animals are facing the danger of dying out.7．I’m trying to make ________the time I lost while I was sick.8．In order to make sure that his children were safe while playing on the beach，he kept ________(watch) over them all the time.9．We were talking about the TV play，and his sudden________(appear) stopped our conversation.10．The boy is running impatiently here and there as if________(search) for something lost on the sports ground.Ⅱ.阅读理解AIt started as a special day for Wesley Autrey，a 50-year-old construction worker in New York City.It was about 12：45 PM，and he was waiting on a subway platform (月台) to take his daughters home before he went to work.He suddenly noticed a man nearby have convulsions (抽搐) and fall down suddenly.Mr Autrey and two women went to help the stranger.The man，Cameron Hollopeter，managed to get to his feet，but then stumbled (绊倒) at the edge of the platform and fell onto the subway tracks.Mr Autrey looked up and saw the lights of the subway train coming near through the tunnel.Mr Autrey jumped onto the track immediately.He realized that he didn’t have time to get Mr Hollopeter and himself back up on the platform before the train arrived，so he lay on top of the man and pressed down as hard as he could.Although the driver tried to stop the train before it reached them，He couldn’t.Five cars passed over them before the train finally stopped.The cars had passed only inches from his head.New York loves a hero.Mr Autrey became an overnight hero and was named the “Subway Superman”．New York City Mayor Michael Bloomberg gave him the Bronze Medallion，the city’s highest honor.He was asked to appear on several TV talk shows.He was also rewarded with money and gifts，such as $10,000 from Donald Trump，a $5,000 gift card from the Gap clothing store，a new Jeep，and Beyonce concert tickets.How did Autrey react (反应) to all this？He said，“I don’t feel like I did anything great；I just saw someone who needed help.I did what I felt was right”．1．Which of the following can best describe Mr Autrey?A．Smart. B．Shy.C．Strong. D．Brave.2．Facing the praise and rewards，Mr Autrey was________.A．quite Calm B．very proudC．rather satisfied D．really surprised3．What would be the best title for the text?A．A good fatherB．A subway supermanC．A Beyonce super fanD．A construction worker4．How does the author develop this text?A．By following the order of time.B．By following the order of importance.C．By expressing different opinions.D．By interviewing different people.BThe idea behind Facebook is to make us feel connected all the time.But in my research，I’ve found that the truth is quite different.Technology，it turns out，has made being alone seem like a problem that needs solving.When young people are alone，even for a minute or two，they feel the need to connect，to get on Facebook or some other social networks and chat.But in connecting，they often end up feeling more isolated.Why？Because by being in constant (不断的) connection，they lose the ability to feel satisfied with their own company (独处)．Facebook can help us keep in touch with our friends，but we too often use it instead of spending face-to-face time with them.And since we feel the need to keep up with them online，we don’t have moments of loneliness where we can collect our thoughts and learn how to be comfortable being alone.—Sherry Turkle，ProfessorFacebook connects more of us to more of our friends and family in more places than we have ever been connected before.Yes，Facebook is a huge time sink—maybe the biggest ever.Many people post useless stuff.And seeing too much of your friends’ lives can make you jealous (嫉妒的)，but it won’t make you lonely.Jane，a former student of mine，who is back in New York after living abroad for ten years，told me that Facebook helps her a lot.The first time she moved back to New York from abroad，She felt disconnected from her family and friends.Now，because of lots of photos and information updates (更新)，she knows what is happening with her friends all the time.In fact，if you are lonely in real life，you will be lonely online as well.—Sree Sreenivasan，Chief Digital Officer5．The underlined word “isolated” in Paragraph 2 means________.A．free B．selfishC．careless D．lonely6．According to Sherry Turkle，we should ________.A．feel satisfied with our lifeB．avoid using social networksC．keep in touch with our friendsD．enjoy moments of loneliness7．What’s Jane’s attitude towards Facebook?A．Hopeful. B．Doubtful.C．Thankful. D．Regretful.8．The purpose of the text is to________.A．educate B．discussC．persuade D．introduceⅢ.七选五The dangers faced by the ocean may seem terrible.In the face of pollution，climate change and other serious problems，what you can do alone may seem little.__1__ Here are some ways to get started：•Be water-wise.All waters on the earth are connected，so you can help keep the ocean clean by using as little fertilizer (化肥) as possible when growing plants in your yard.__2__Much energy is wasted in transporting foods from far away.What’s more，remember that trash you throw away doesn’t disappear.So don’t throw wastes into the ocean.•Be fish-friendly.Scientists guess that up to 90% of large predatory fish (those that eat other animals) have disappeared since humans began heavy fishing.__3__ You should choose sustainable (可持续的) seafood in restaurants.When fishing on your own，make sure you follow all local catch limits.•Cut carbon.We should try to reduce the amount of carbon dioxide given off as we go about our daily activities.__4__•__5__A trip to the ocean is a great way to learn more about the ocean.But when you visit，make sure you aren’t causing harm.If you plan to take a cruise for your next vacation，do some research to find the most eco-friendly way.A．Travel the ocean in a responsible way.B．To protect fish，you need to watch what you eat.C．If possible，try to look for products grown close to where you live.D．Don’t buy products that are made from sea animals or animal parts.E．But if we begin working together now，we can make a huge difference.F．As a result of global warming，everyone needs to learn how to save energy.G．To achieve this，we should try to walk，bike or take the bus to work or school.课时作业(十一)Unit 3Computers 答案Section ⅢLearning about Language & Using LanguageⅠ.单句语法填空1．答案：personal2．答案：arises3．答案：to deal4．答案：in5．Professor Smith is so busy with the research________ he has no time left for any other activity.答案：that6．答案：destroyed7．答案：up8．答案：watching9．答案：appearance10．答案：searchingⅡ.阅读理解A语篇解读本文是记叙文。

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。

必修二Unit 3 Computers using language课时作业 Ⅰ.阅读理解 A I was so fortunate today to be able to offer my love and help to an older lady at my local supermarket. I saw her standing there. I felt quite strange about such a situation. What was she looking at? As I looked, I found it was a “Shredded Pork Bun Meal Kit”， which is a service that sends customers food ingredients and recipes for them to prepare their own fresh meals. “That's new，” I thought. Then I watched as the lady began to dig into her handbag and tried to pull out one of the biggest magnifying glasses (放大镜) I had never seen in my whole life! “Oh, she can't read it，” I realized. So I stood there and continued watching her. The voice in my mind often asks me to do the right thing. It told me to help her. But I argued back saying, “No. I won't offer help. It will only embarrass her and she is OK now anyway. She has the world's biggest magnifying glass to help her！” And I stood there longer. But the voice came back, “Help her, Nicole. Don't be embarrassed. Just do it. Offer your help.” So I did it. I read and explained all the things that were included in that box. I read out the ingredients, the instructions on how to cook it and so on. She didn't end up buying it, but she was still quite grateful. I walked away knowing that I had helped her and made the right choice. Mostly, I had reminded her that people in this world still care about the old. She was seen. She was loved. And she mattered so much that a complete stranger took time to help her. And that stranger was me, a person who argued and didn't want to do so in the beginning. So grateful I am when I choose to listen to the voice in my heart. It is because of love. Love is all that ever really matters. I also get happiness through helping her.

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.
