Unit 3 Computers 单元测试题2第二部分：阅读理解（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
ADear students,Most of us get some exercise walking or riding our bikes to school, but that just isn't enough. Why not get into shape by playing the most popular sport in the world — soccer?Two weeks ago, Ms. Goldstein, the physical education teacher, posted a notice about an exciting new soccer club (for Grades 3-5). To join, all you have to do is sign your name and be at school for the fun of it on Saturday mornings. You'll make new friends and share information about famous teams and players.Ms. Goldstein will teach, so you'll learn basic skills and new techniques (技巧) to improve your game. That's good news because soccer is a game you can love three seasons a year. The only time you can't play is when there is snow.However, it is hard to believe that only nineteen people signed up for the new club. Maybe kids don't want to give up their Saturday mornings. But if you think about how we spend Saturday mornings now, soccer looks good. Doing housework and watching TV are not as much fun as playing soccer with friends. If you didn't sign up because you've never played soccer before, don't worry. Beginners are welcome and Ms. Goldstein will give you more help.Just act now! The equipment is cheap. All you have to bring is your feet.The Students' Union21.

Then we went to his house and asked if he could give us our ball. He said, “No”. We felt helpless. But suddenly we came up with an idea. There was a water tank (水箱) behind the man's house. I told Kavya, “We can climb onto the water tank and jump over the gate.” Kavya agreed, but we were both wearing skirts. We couldn't climb in those. “We can get it back tomorrow,” said Kavya.The next day we went there with Kavya's brother Vijay. He said, “Shout loudly if you need me.” Kavya climbed onto the water tank first and then she climbed down into the man's house. I followed her. We were looking under a bed for the ball when we heard a noise. It was Vijay. “Mother is calling you,” he said in a low voice.We hurried out taking the lost ball with us. Along with the ball was a surprise! But we had to leave the house quickly. When we reached Kavya's house, the TV was on. It was news time. I couldn't believe my ears when it said that 20 gold bars were stolen from a gold shop. They showed a picture of the gold bars, which were exactly like the one we had seen in the man's house.We told the story to Kavya's mother right away, and she called the police. Soon the police caught the man. They found all the gold bars in his house. A few days later a policeman came to us and said, “Thank you for helping us catch the guy. Here is abag for all of you.” When we opened it, it was full of storybooks and lovely toys. Standing beside us, Kavya's mother was all smiles.24.

At the age of two, she moved with her mother and two sisters to Timmins, a town northof Toronto. When Shania was eight years old, her mother took her to many different bars, clubs and concerts to perform (表演). In high school, Shania joined a local band (乐队), with which she often performed. After that, Shania moved to Toronto, where she continued singing.When Shania was 21 years old, her parents were killed in a car accident.

All his friends already had one, so his mom and dad agreed. During the first few weeks, Jason spent a lot of time in front of his computer because he had to learn how it worked. He was really interested in learning all about it and he even started writing computer programs himself.One day Jason found a website where he could play chess either against the computer or against other people from all over the world. From then on, Jason seemed to have just one interest in life, his computer. Whenever his parents told him that he was spending too much time with his computer, Jason went into denial. He did not think that he had a problem at all.Then the unthinkable happened: Jason's computer broke down. But his parents decided not to buy him a new one. Jason said that he needed a computer for school, and he promised that he'd spend less time with it. But his parents refused to give in. Finally, Jason felt so hopeless that he took the only way out and killed himself.Robert Johnson, a psychologist (心理学家) on the subject, says, “Computer addiction (沉溺) is an illness that can influence anyone of us. Nowadays, increasing numbers of people are spending more and more time working with computers. While this isn't a problem for most users, some people, especially teenagers, often use thecomputer to get away from the real world. This is especially true of shy people. For them, meeting people online is a way of hiding their true selves. In cyberspace, they can be whoever they want to be and create their own virtual (虚拟的) world. But what happens when they can no longer enter their virtual world?”32. Why did Jason want to buy a computer according to Paragraph 1?A. To play chess.B. To make friends.C. To avoid being an outsider.D. To write computer programs.33. By saying “Jason went into denial”, the author means _____.A. Jason would not listenB. Jason enjoyed himselfC. Jason would turn it offD.

It, however, requires the use of biosensing earphones and other fitness tracking equipment! It can play your favourite music while you work out and all you have to worry about is the exercise you’re doing.Deep TextDo you ever wonder how an ad appears suddenly just when you are looking for something similar? This is because of Deep Text. I t uses realtime consumer information to produce data which in turn is used to target consumers. Thus, if you search online for flight tickets from Bangalore to Delhi, it is very likely that an ad relating to hotels in Delhi will soon follow.Hello EggIf you live alone and miss your mother because you always miss your breakfast or don’t know what to eat for dinner, then Hello Egg is exactly what you are looking for.

D．D|S360.BHadi Partovi，founder of believes every student should learn the basics of computer science just like they do math, physics, or biology, regardless of what they want to do in the future. The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis (光合作用), even though not every student is going to be a botanist. To spark students' interest, he created the “Hour of Code”，which introduces the world of computing to anyone, from ages 14 to 104, in a fun, interactive manner. Observed annually during Computer Science Education Week, the event now draws tens of millions of kids from over 180 countries.The “Hour of Code”，which can be scheduled anytime during Computer Science Education Week, begins with an introductory video on computer science. Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience. Though each project is designed to last just 60 minutes, beginners can deal with as many challenges as they desire.To help introduce computer science into classrooms on a more regular basis, has also developed a catalog of online courses that can be incorporated (纳入) in a school's regular curriculum. Since the nonprofit began offering the courses in 2013, over 704,000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.Thanks to the efforts of the pioneer, about 40 percent of U．S. schools now offer computer science as a subject, The number is even higher — an impressive 70 percent — if afterschool offerings such as robotics clubs are included. Even more encouraging, eight years ago, just 19,390 students took the Advanced Placement Computer Science exam. By the spring of 2017, the number had jumped 415 percent to 99,868.4．Why did Hadi Partovi create the “Hour of Code”？A．To train computer scientists for the future.B．To introduce the world of computing to teachers.C．To add a program to Computer Science Education Week.D．To help people learn computer science in a fun way.5．Why do we call the event the “Hour of Code”？A．It is observed annually.B．It can be scheduled anytime.C．Its projects last sixty minutes each.D．Its tasks can be sorted by coding experience.6．What do we know about Code. org's online courses?A．Schools can use them regularly in their classrooms.B．They help the developer make lots of money.C．Over 704,000 teachers have been learning them.D．They have existed for over 10 years up to now.7．What do the numbers show in the last paragraph?A．The efforts of Hadi Partovi.B．The influence of robotics clubs.C．The effect of Hadi Partovi's efforts.D．The development of many U．S. schools.CWorld Environment Day is celebrated annually on June 5th and was created to inspire people around the globe to take an active part in environmental protection and learn more about ways we can help to guarantee the future of our planet is safe.The very first World Environment Day took place in 1974, established by the United Nations General Assembly on the first day of the Stockholm Conference on the Human Environment that took place in 1972. Each year the United Nations pick a theme and a host city where anyone who is concerned about the environment can talk about environmental topics with others, followed by different kinds of exhibits to promote environmental awareness. Environmentalists, academics and scientists come together to bring new ideas on the table concerning the environment.The 2018 World Environment Day is hosted by India, and the theme is Beat Plastic Pollution. It urges people to explore and choose supportable alternatives like paper or cloth bags to reduce the production and use of disposable plastic, which makes up 10% of all of the waste. Even though the United Nations pick a specific host city every year, people around the world still celebrate World Environment Day in their hometowns with parades (游行), concerts, cleaning up and tree planting and all kinds of green actions to work towards having a beautiful planet and battling pollution.World Environment Day is not a public holiday, so you won’t be getting the day off work or school, but if you want to celebrate, why not bring it to the attention of your parents, friends, colleagues or classmates? World Environment Day is all about working together to take action for the planet, so try to get everyone you know interested in helping do something. Things as small as making sure people have a way to recycle can make a difference. You could also try beautifying your neighborhood by planting gardens, learn about green foods, raise money for a local wildlife conservation group or simply learn about the effects of different products on the earth.8．Why is World Environment Day set up?A．To make people know more about nature.B．To ask people to help to protect the globe.C．To warn people of the danger of air pollution.D．To encourage people to plan the earth’s future.9．What do people do on World Environment Day?A．Decide a host city.B．Hold a theme party.C．Discuss environmental ideas.D．Show some plastic products.10．Which of the following words is the closest in meaning to “disposable” in Paragraph 3?A．Highcost.B．Poorquality.C．Secondhand. D．Singleuse.11．What’s the main idea of the last paragraph?A．Every bit of effort counts.B．Doing is better than saying.C．Many hands make light work.D．Nothing is impossible to a willing heart.DNearly every week, we hear news about the latest successes and failures in driverless vehicles. But we hear little about how other industries are developing this same kind of technology. One industry heavily involved in researching and developing artificial intelligence, or AI, is agriculture. Companies are experimenting with hightech tools that can help farmers save time and money, while reducing environmentharming chemicals.One of the companies is ecoRobotix of Switzerland. It created a robot equipped with AI and cameras to identify all plants on a farm. The robot has four wheels to carry it through the fields in search of weeds. Computercontrolled arms then lower and spray the weeds with small amounts of herbicide (除草剂). Company officials say the robot can fully operate on its own for up to 12 hours a day while being powered by the sun. It uses the same kind of sensor and positioning technology used to guide driverless vehicles. A farmer can also control the equipment through a smartphone.The cofounder of ecoRobotix, Aurélien Demauret, says the farm robot can kill weeds with 20 times less herbicide than traditional methods. This is because the system uses exactly the right amount of chemical in the exact place required to kill the weeds. Currently, farmers spread weed killers over massive areas to destroy unwanted plants.Another company developing farm robotics is Californiabased Blue River Technology. The company has a system called “See & Spray”，which it claims was the world’s first smart sprayer. The system — which is connected to the back of a tractor — is also equipped with AI to identify and chemically kill only the weeds. It can also spray chemicals on wanted plants to help them grow. Ben Chostner, vicepresident of business development for Blue River Technology, explainsin a company video that See & Spray technology uses the same deep learning methods used in facial recognition. “The first time the machine saw a pigweed, it didn’t know what kind of plant it was.

microprocessor and a memory chip or only a memory chip that is not programmable.The microprocessor card can add, delete, and deal with the information on the card, while a memorychip card can only do one thing.Smart cards, unlike magnetic stripe cards, can do many different things and hold a lot of information.In this way, they do not need to get information from a faraway place when they are used.Today, there are several kinds of smart cards, all of which are very popular in the market: IC (Integrated Circuit) Microprocessor Cards (Chip Cards) offer a larger memory and better security than the traditional magnetic stripe cards do.Chip cards can also hold data. These cards are used for manythings.Thus, chips have been the main platform for cards that hold a secure digital identity.Some examples of these cards are：Cards that hold money.Cards that provide safe access to a network.Cards that allow setting stop boxes on televisions to remain safe from privacy.Optical Memory Cards look like cards with a piece of CD on the top.Optical Memory Cards can store up to 4MB of data. But once written, the data can not be changed or removed. Thus, this type of card is good for keeping records, such as medical files, driving records or travel histories.Today, these have no processors in them(although this is coming in the near future)．While the cards are almost as cheap as chip cards, the card readers are expensive.Title：21.________ Cards12.D 13.B 14.A15.A 16.A 17.B 18.C 19.D 20.B21.Smart 22.Advantages 23.security 24.Memory 25.doctors 26.travelers 27.cost28.Unchangeable 29.readers30.memory。
