Unit 9 Future jobsTask 1: Understanding ReadingIn this lesson, we will explore the topic of future jobs. It is important to think about our future careers and what we want to achieve in life. By discussing and researching different job options, we can make informed decisions about our future paths.1.1 Reading ComprehensionTo start, let's enhance our reading comprehension skills by reading a passage about the future of jobs. This passage will provide us with valuable insights into the potential careers that may arise in the future. Pay close attention to the details and main ideas presented in the text.The Future of JobsThe world is rapidly changing, and with it, the types of jobs available to us. In the past, many jobs were centered around manual labor, such as farming and manufacturing. However, as technology continues to advance, we are seeing a shift towards more knowledge-based jobs.In the future, new job roles are expected to emerge, such as virtual reality designers, sustainable energy engineers, and genetic counselors. These jobs will require specialized skills and knowledge in fields that are still developing.It is also predicted that automation will play a significant role in our future jobs. Many routine tasks will be taken over by machines and artificial intelligence, freeing up human workers to focus on more complex and creative tasks. This means that individuals should consider developing skills that complement and go beyond what machines can do. 1.2 VocabularyBefore moving forward, let's take a moment to familiarize ourselves with some key vocabulary related to future jobs. These words will be usefulas we delve deeper into this topic.1. Virtual reality: the use of computer technology to create a simulated environment2. Sustainable energy: energy obtained from sources that are notdepleted with use, such as solar or wind power3. Genetic counselors: professionals who provide guidance and support to individuals or families who may be at risk of genetic disordersBy understanding these vocabulary words, we can better comprehend the concepts discussed in the text and expand our overall knowledge offuture jobs.Task 2: DiscussionNow that we have read the passage and learned some new vocabulary, let's engage in a discussion about future jobs. Working in pairs or small groups, discuss the following questions:1. Which future job mentioned in the passage interests you the most? Why?2. Do you think automation will have a positive or negative impact onour future jobs? Why?3. What skills do you believe will be most valuable for future professionals?During the discussion, try to provide detailed answers and support your opinions with examples or personal experiences.Task 3: PresentationTo conclude this lesson, we will have a presentation session where each group or pair will share their discussion outcomes. Prepare a brief presentation highlighting the main points of your discussion, including the most interesting future job, the impact of automation, and theskills required for future professionals. Be confident, clear, and concise during your presentation.Remember, the aim of this task is to reflect on the passage, engage in meaningful discussion, and practice your presentation skills. Let's embrace the opportunities that future jobs hold for us and strive to make a difference in the world!End of the Document.Note: This document is solely created for educational purposes and should not be used for any commercial or advertisement purposes.

Unit 9 Kids and Computers Digital Danger 课文翻译
Unit 9Kids and Computers: Digital DangerAlison Sperry1. There's a familiar saying, "Play is children's work." Through play, people who study child development tell us, children develop the skills and outlooks that determine the adults they will become. Playing house or school, for example, helps them "try on" the roles of Mom or Dad or teacher. Athletic activities help kids develop coordination, learn to work as part of a group, and gain confidence and a sense of fair play. Even solitary activities like reading connect children with the wider world, encouraging a sense of empathy with the greater human family.2. But in very recent years, other forms of entertainment have had an enormous impact on growing children. For many kids, computer activities and video games now take up much --even most -- of the time formerly devoted to more traditional forms of play. Entering adulthood now are the first Nintendo babies, a generation raised more on Virtual Boy and Mortal Kombat than baseball and Uncle Wiggly. How have they been affected by this change in the concept of "play"? Social scientists, parents, and talk show pundits will be debating the question for years to come. But we can start drawing our own conclusions. As amusing and ingenious as electronic entertainment can be, children -- and society they live in -- are the losers when they rely on these forms of fun. Unlike traditional games and toys, "wired" entertainment encourages kids to be unimaginative, socially immature, and crudely desensitized to the world around them.3. Watch a child take a ball of Play-Doh in her hand and begin to roll it experimentally. First it's a simple ball, then a snake. The snake might become a figure eight or a bracelet. She coils the bracelet on top of itself to create a pot that she uses for a make-believe tea party. Next she smashes the pot back into a ball, which may next morph into a snowman, a horse's head, a bunny, a sea serpent, or a skyscraper. With nothing but her hands and an inexpensive chunk of flour and salt, she forms a universe in which she makes the rules and creates the inhabitants. When she tires of it, she can wad it back into a shapeless mass that awaits her next creative impulse. The act of playing with the Play-Doh sparks other interests —maybe she'll work with modeling clay that she can bake into a permanent form, or paints, or papier-mâché Although she doesn't give what she's doing a great deal of thought, she's learning something valuable: I am a creator. I can give my ideas tangible form.4. A video game, on the other hand, is cynically programmed to give the illusion of creativity. The player is given various choices at every turn —Which door will I go through? Which weapon will I use? What clue shall I read? — But they are choices in the same sense that a pigeon's pecking at a lever to get a grain of corn is a choice. The player is as much a tool of the game as the joystick. Her momentary fun is unsatisfying because it leads not to any genuine sense of achievement but only to the hypnotic experience of watching someone else's creation unfold. Hand a ball of Play-Doh to a child reared on the sterile adventure of video games, and you're apt to get a blank look and the hesitant question, "What do I do with it?" The video game player learns her own lesson: I don't create. I let someone else's creativity happen in front of me.5. It's a beautiful Saturday in autumn, and a group of kids are playing a pickup game of soccer. A dispute arises about whether a kick went over the foul line. Some of the kids are sure it did; others insist that it did not. Voices are raised; tempers flare. Maybe a hothead or two will stalk off the field. But the sky is crystal blue, and there are chores waiting at home. Making a quick calculation about the relative benefits of continuing the game, the players work out a solution. Maybe they replay the kick. Maybe they flip a coin. Maybe they agree to say that the ball was fair, or foul. Their willingness to compromise, to accept the idea that such give-and-take is part of life, allows the game to proceed. The players move on, having learned a small lesson about getting along with others.6. Contrast that scene with the world of the Internet chat rooms, where many adolescents spend uncountable hours. On that same lovely Saturday, a young Internet queen hunches over her keyboard, alone in her room. Her buddy list includes dozens, even scores, of "friends" she's never met. Her fingers fly across the keyboard as she races from one dialogue box to another, keeping up multiple conversations. These are peculiar conversations, however, including none of the vulnerability that is part of real-world friendship. In the buddy-chat world, status is based on the ability to keep up a rapid pace of one-liners, insulting zingers, caustic put-downs. The chat queen's most intimate friendships take the form of brief alliances with buddies who join with her to "flame" another chatter who has displeased them. If that ally eventually becomes annoying, too, zap! She can instantaneously erase him from her buddy list, or even block him so he is unable to contact her again. It's no great loss. There are literally millions of new acquaintances waiting to be picked up in a chat room to fill that void. The lesson: I shouldn't have to work at relationships. They come and go instantly and at my convenience. If someone displeases me, I can make that person disappear.7. When kids sit down to play Monopoly, they form a loosely knit group that is still part of the world around it. When company arrives at the house, it's no problem to halt thegame briefly. The players can greet visitors, laugh together, talk about the game, even quickly rearrange it to include new players. Even after the game continues, chatting with other players and non-players is easily accomplished. Despite their involvement in the game, the players are not ruled by it. Human contact, courtesy, and communication are not seen as threats to their enjoyment. They are learning that they can enjoy their own activities and still be sensitive to the larger world around them.8. Contrast this board game scene with one that has become depressingly familiar in many living rooms. Visitors arrive at a home to find a child hunched in front of the TV set, video controls in his lap. Even when spoken to directly, he does not pull his eyes from the screen. "I'm playing!" is his furious response if the visitors persist in trying to engage his attention. Far too often, even his parents, intimidated by the high-priced, high-tech gadget that has sucked their child's humanity away, tiptoe around rather than disturb him. The game itself is all too likely to be one that presents the most hideous suffering as entertainment, with the player in the role of psychotic killer -- maybe in Duke Nukem, with its "twenty-three levels of nonstop carnage!" or Bloody Roar, which offers the player "more ways to maim, crush, and devour your enemies than ever."9. The lesson?10. Isn't it too awful to think about?1. 有一句众人皆知的俗语：“玩是孩子们的工作。

Unit 9Task 1Compere: And now for our first question. It comes from Mrs. June Moore. Mrs. MooreMrs. Moore: Does the panel think that computers will change our livesCompere: Mrs. Moore wants to know if computers will change our lives. Philip BarnesPhilip Barnes: Computers have already changed our lives. Business is more efficient.Planes and trains provide a better service...Miss Anderson: Just a moment, Mr. Barnes. You may be right about business, but how many people have lost their jobs because of computers Computershave changed our lives, but I don't want my life changed.Arthur Haines: Excuse me, Miss Anderson. We're talking about our lives, not your life.The computer will affect everyone in the world. Records can be keptof everything we do. Records will be kept of all our private lives. Inmy opinion, the computer is the greatest disaster of the 20th century. Phyllis Archer: Could I interrupt Arthur Haines says the computer is a disaster, but the computer is a machine. It was invented by people; it is used by people.If the computer is a disaster, then people are a disaster.Compere: Thank you, Phyllis Archer. Thank you, panel. And thank you, Mrs. Moore.Task 2【答案】A.1) It includes a 9-inch TV screen, a keyboard with 46 numbers and characters on it, a printer, and two disk drives.2) It's all contained right on the floppy disk.3) It’s much better than a typewriter in that one can move words or sentences from place to place or make corrections or changes right on the screen, and never have to erase on paper.4) It can help him make a monthly budget for his household with electronic spreadsheet software.B.1) loads your program into the machine2) typewriter, typewriter,3) turning the computer on and loading a program4) the different things the program can do【原文】Narrator: For Harvey Van Runkle, it was love at first sight, or should we say, love at first byte Really, it is 64,000 bytes—that's the size of the memory on hisnew BANANA-3 personal computer. It all happened by accident. His wife,Charlotte, had sent him out to buy a new toaster, when he found himselfstanding in front of a computer display at the BANANA Computer Store. Salesman: Yes, ladies and gentlemen, this little computer is going to change your lives.Just consider the hardware: You have a 9-inch TV screen. That’s yourvideo display terminal. You have a keyboard with 46 numbers andcharacters on it. You have a printer that will give you paper printouts ofyour work in three colors. You have two disk drives—one inside thecomputer terminal and one outside. This computer can do anything! Nowlet’s have a little demonstration. Who would like to try the newBANANA-3 computer You, sir. You look interested. Step right up and trythe BANANA-3.Harvey: What's a d-disk driveSalesman: That's the part of the computer that loads your program into the machine. Harvey: Oh. What's a programSalesman: The program That's your software. That's the instructions. It's all contained right on this floppy disk here. The instructions on this disk tell thecomputer what to do.Harvey: Oh, you mean like my wife. She always tells me what to do. Salesman: Exactly. Now what type of program would you like I have word processing,I have electronic spreadsheet...Harvey: What's word processingSalesman: Word processing is using the computer like a typewriter. But it's much better than a typewriter. You can move words or sentences from place toplace or make corrections or changes right on the screen. You never haveto erase on paper. It's a wonderful little program! Would you like to try it,Mr...Harvey: Van Runkle. Harvey Van Runkle. I've never used a computer before... Salesman: It's easy. First we start up the machine, and then boot up a program. Harvey: Boot upSalesman: That's computer talk for turning the computer on and loading a program.There. Now we look at the menu.Harvey: Menu But I just had lunch. I'm not hungry.Salesman: No, no. This is a program menu, not a restaurant menu. It shows the different things the program can do. For example, here we have "file". Ifyou select file, you can choose which of your documents you want to workon. And here’s “edit”. This gives you ways to co rrect your document. Harvey: Gee, this is great! There's only one problem.Salesman: What's thatHarvey: I don't have any documents. I'm a plumber.Salesman: But you have bills, don't youHarvey: Yeah, but...Salesman: Well, with our electronic spreadsheet software, you can make a monthlybudget for your household.Harvey: No. My wife, Charlotte, does that.Salesman: Well, now you can do it, Harvey.Harvey: I don't know...Salesman: And you have friends, don't youHarvey: Yeah, well there's my brother-in-law Bob...Salesman: Great! You can write letters to Bob on your new BANANA-3 computer!Harvey: Okay. How much is itSalesman: Never mind. Do you have a credit cardHarvey: Well, sure...Salesman: Great. Joe, get Harvey here signed up, will you He wants a BANANA-3 with a printer and software. Okay, step right up, ladies and gentlemen. Thiscomputer can do anything!Task 3【答案】A.1) They are important because they are able to measure quantities such as electricity and temperature.2) Digital computers.3) Only one person at a time can use them.4) It is because their owners do not spend enough time learning how to operate them efficiently.5) Each person who uses a minicomputer has a computer terminal that is connected to the minicomputer by interface wires. With the help of the operating system, the CPU is able to divide its time and perform for all the users.B.Similarities and Differences between Microcomputers andThere are two primary kinds of computers: analog computers and digital computers. Unless you are a scientist, you probably will not use analog computers. These computers are important because they are able to measure quantities such as electricity and temperature.In contrast, digital computers perform their tasks by counting. Some digital computers are built to help solve only a specific kind of problem. For example, digital computers that monitor airplanes flying in and out of airports are built only for that task. Most digital computers, though, can be used to help solve many kinds of problems. Among them, microcomputers and minicomputers are two kinds of common digital computers.Microcomputers, also called personal computers, are the newest computers. Many are about the size of a very small television set. Some, however, are so small and light that people can carry them easily on business trips. Because computermanufacturers produce an enormous amount of computer hardware, it is possible for anyone to own and use a microcomputer. Therefore, we now see these machines in many homes, schools, and businesses. There is one disadvantage to these computers, though. Only one person at a time can use them. Also, many people who buy microcomputers do not understand what these machines can and cannot do. Some experts say that almost half of all micro-computers are not used often because their owners do not spend enough time learning how to operate them efficiently.Like microcomputers, minicomputers are used in small businesses. However, they are larger than microcomputers and are used more frequently in large offices and businesses than in small businesses. Another difference is that more than one person can use a minicomputer at the same time. We call this time-sharing. Some minicomputers can have more than a hundred people time-sharing them. Each person who uses a minicomputer has a computer terminal that is connected to the minicomputer by interface wires. But even though more than one person can use a minicomputer, the computer has only one CPU. With the help of the operating system, the CPU is able to divide its time and perform for all the users.Task 4【答案】A.1) It wasn't the typical low mechanical voice that sounded like a record being playedat too slow a speed. It sounded natural. It had charm to it.2) Lupa had once heard that even a sophisticated analog computer couldn't pick up certain subtleties in the English language, no matter how good the programming is.3) When Lupa stood up and walked around the room, it was evident to her that somewhere in the building, listening through an intercom was someone with a microphone.B.1) They're running a contest. The kids are supposed to name me. I'm dreading the whole thing, believe me.2) You know something; I thought you'd be different. Just once today I was hoping I'd get someone who wouldn't try to beat the program.3) You wouldn't happen to know what day of the week September the fourteenth, 1321, fell on, would youIt was a Sunday; but how do you know whether I'm right Thank you for visiting the computer exhibit.【原文】Lupa laughed. She liked the voice that had been selected for the computer. It wasn't the typical low mechanical voice that sounded like a record being played at too slow a speed. It sounded natural. It had charm to it."Do you have a name" Lupa asked."Not yet," the computer answered. "They're running a contest. The kids are supposed to name me. I'm dreading the whole thing, believe me."Now Lupa thought this was clever, the way they had programmed the computer. She wondered if there was some way to screw up the program. She had once heard that even a sophisticated analog computer couldn't pick up certain subtleties in the English language, no matter how good the programming is, so she decided to give it a try."My paws give me pause," she said.The computer was silent."My paws give me pause," Lupa repeated. "It's a clause without claws."Lupa waited in silence for a response."You know something," the computer said. "I thought you'd be different. Just once today I was hoping I'd get someone who wouldn't try to beat the program."Lupa smiled. "This was marvelous," she thought to herself. "They'd thought of everything.""Sorry," she said. "Mi dispiace.""Ah, you speak Italian," the computer said with some sarcasm."Qui, d'accord," Lupa answered. "C'est vrai.""And French, too. Your French is better than your Italian. Though neither one is great. Now, if you'll excuse me, I have to shut down. It's closing time."Lupa stood up and walked around the room. It was evident to her that somewhere in the building, listening through an intercom was someone with a microphone. She thought about how to test for this."You wouldn't happen to know what day of the week September the fourteenth, 1321, fell on, would you" Lupa asked."It was a Sunday," the computer answered, "but how do you know whether I'm right Thank you for visiting the computer exhibit."Task 5【答案】A.1) b) 2) c)B.1) F 2) F 3) F 4) THello. I think we can begin now if you're ready. Um, today I want to talk to you about computers, about the impact of computers on how we talk, on the ways we talk. Now of course we all know that computers have changed our lives in many ways. Stop and think for a minute about how we use computers in our everyday life. It's hard to think of anything we do that hasn't been changed by computers. For example, computers allow us to get money directly from our bank accounts at cash machines. At hospitals, computers help doctors understand what is wrong with patients. We can use computers to help us decide which color to paint our houses, which hair styles to have, or which dresses or suits would look good on us--lots of professional and personal uses. Computers are simply a part of our lives, and, I think it is safe to say, they will continue to be. What I'd like to look at today is how the use of computers has had an impact on our language--how computers have changed the expressions we say, the words we use.First, let me give you some examples. These are examples from English that I'd like you to think about. The first example is this. Someone at an office says, "We'd like to have the project online by next Monday." In computer talk "online" means started or working. So this statement means that we'd like to have the project started and going by next Monday.The second example is from a discussion or seminar. Someone might say, "Let'stake this discussion offline until tomorrow." To take a computer "offline" means to disconnect it or take it out of the system. What do you think it means to take a discussion offline To take a discussion "offline" means to stop talking about it. This example means "let's stop discussing this now and talk about it tomorrow."The third example is: "I'll try to interface my plans with yours." To "interface", in computer talk, means to do something so that different computer parts or software can work together. So "I'll try to interface my plans with yours" means that "I'll try to change my plans to fit with yours." People still say, of course, "I'll try to change my plans to fit with yours." But now we might also start to hear people say, "I'll try to interface my plans with yours," or "Let's see if we can interface our schedules so that we can meet next week."Let’s try one more example. Our fourth example might take place at home. Someone says,” I just can’t access where I left my car keys.” In computer talk to “access” something means to make information available. If I can’t access where I left my keys, I don’t have this information available for me to use. What would be another way to say this Of course, we could also say, “I can’t remember where I put my keys.”Task 6【答案】1) Cyber ethics.2) It will focus on teaching educators how to teach their students cyber ethics.3) Because it’s not done verbally so that people can overhear it; they think it’s anonymous on the Internet.4) She was a former principal and an adjunct professor at Marymount University,teaching curriculum development and technology in the classroom.5) Young computer users do not see hacking, e-mail threats, cyber talking, Intellectual Property Rights violations and virus distribution as crimes.6) She said that it is something that needs to be instructed as routine curriculum, and student should know that these behaviors are as unacceptable in cyberspace as in the physical realm.【原文】Although schools are doing a better job at teaching children how to use the Internet, they are not addressing cyber ethics. "Cyber Ethics: Teaching Responsible Use of Technology" will focus on teaching educators how to teach their students cyber ethics. When typical crimes are committed on the Internet, students do not see them as a crime, said Cherie Geide, the conference director."They don't see anything wrong with it because they see it as a prank. It's more unacceptable to do it verbally where people can overhear it. They think it's anonymous on the Internet," said Geide, a former principal and an adjunct professor at Marymount University, teaching curriculum development and technology in the classroom.Geide said young computer users do not see hacking, e-mail threats, cyber talking, Intellectual Property Rights violations, such as in software or music, and virus distribution as crimes."This is something that needs to be instructed as routine curriculum," she said, "that this behavior is as unacceptable in cyberspace as in the physical realm.Task 7【答案】A.1) It's Microsoft's SANTA that the kids can't resist; it's the ultimate software with atraditional twist—recommended by no less than the jolly old elf, and on thepackage, a picture of Santa himself.2) Father did last-minute Internet shopping; Mum and I had just settled down for a long winter’s nap.B.1) not a creature was stirring, except father's mouse.

So spin up your drive from now on, Christmas runs only on Windows 95.It's Microsoft's SANTA that the kids can't resist; it's the ultimate software with a traditional twist—recommended by no less than the jolly old elf, and on the package, a picture of Santa himself."Get 'em young, keep 'em long" is Microsoft's theme; and a merger with Santa is a marketer's dream. "To the top of the NASDAQ! To the top of the Dow! Now dash away! Dash away! Dash away—wow!"And Mum in her handkerchief and me in my cap, had just settled down for a long winter's nap. When out on the lawn there arose such a clatter, the whirr and the hum of our satellite platter. As it turned toward that new Christmas star in the sky, the SANTALITE owned by the Microsoft guy. As I sprang from my bed and was turning around, my computer turned on with a Jingle-Bells sound.And there on the screen was a smiling Bill Gates next to jolly old Santa, two arm-in-arm mates. And I heard them exclaim in voices so bright, have a Microsoft Christmas, and to all a good night!Task 8【答案】A.1) You would need a computer because of its "memory" and speed; a computer can consider more factors than a person can.2) The reservation clerk uses a machine to record information about where you wantto go and the flight number of the plane that will take you to your destination.3) The computer not only determines what seats are available at what prices, but it also prints the tickets at the same time.B.1) there is a limit to the number of considerations the human mind can2) analyzing this factor in relation to information about the business that has already been programmed3) in which computers are being4) whether or not there is space for youC. See the last paragraph but one in the script.【原文】Suppose you are a manufacturer of bicycles. You are trying to decide whether or not to build a larger factory or to buy more machines. You could just say to yourself, "Business has been good. We've sold a lot of bicycles recently, so I think we ought to expand our plant."Or you could consider such questions as the following: How much would the changes cost Can the bicycle-riding population be expected to increase or decrease Many such questions would have to be answered, but there is a limit to the number of considerations the human mind can take into account.In a situation like this, you would need a computer. Because of its "memory" and speed, a computer can consider more factors than a person can. Does the bicycle manufacturer wonder how the weather will affect bicycle sales The computer can tell him by analyzing this factor in relation to information about the business that has already been programmed into the computer.This is just one of many situations in which computers are being used today. This new servant of man is only about twenty-five years old, but it has already changed the lives of more than 200 million Americans. Wherever the citizen turns, he finds a computer working.Computers are used when one reserves space on an airplane. Walk into any airline office. Before selling you a ticket, the reservation clerk uses a machine that looks like a typewriter to record information about where you want to go and the flight number of the plane that will take you to your destination. This information is sent instantly to a central computer that may be many kilometers away from the airline office. Within seconds, the computer informs the clerk whether or not there is space for you on that plane.Such reservation systems are now in increasing use. They are also employed by hotels, by com-panics that rent cars, and by offices that sell tickets to theaters and sports events. The computer not only determines what seats are available at what prices, but it also prints the tickets at the same time.When computers are used in the way just described, some part of the system can actually be seen. Usually what one sees is a machine that looks like a typewriter; it is called a computer terminal. But computers are also used in unseen ways. For example,they determine how much time there should be between traffic signals to prevent traffic problems and to keep millions of cars moving in an orderly flow. When you buy an automobile, a factory process that is controlled by a computer enables you to obtain a car with your own choice of colours and special features in just a few weeks' time. In medical laboratories, computers have reduced the errors in testing, and they have saved doctors countless hours of work. Before long, medical histories of all Americans will be kept in computer "banks". If a person becomes ill far from his home, local doctors will be able to get his medical record immediately. In science, the computer has performed in minutes experiments which would have required thousands of hours of work by human hands and minds.The United States is not the only country affected by the "computer revolution". All the major countries of the world have computers, and the developing countries are increasingly aware that computers play a big part in their economic advancement.Task 9【答案】A. 1) a) 2) b) 3) c)B. 1) T 2) F 3) FC.1) potential criminals: Computer crime2) using less obvious and less easily remembered passwords that allow access to3) limit the user's access to information as well as the operations the userD.Courts are being tougher and computer security is improving. Computer security is getting more sophisticated. For example, less obvious passwords are being used, and access-control software and "dial back" systems have been developed. Scrambling devices and audit trails are also available.【原文】Let's talk a little now about what is being done to stop computer crime. First, the courts are getting much tougher on hackers. They are punishing computer criminals more severely. They are trying to send a strong message to potential criminals: Computer crime is serious. If you're caught doing it, you'll be punished. This is seen as a way of preventing hacking.Computer security is getting more sophisticated. It's being improved by using less obvious and less easily remembered passwords that allow access to systems. These passwords should be given to the minimum number of people.Access-control software is becoming more common. This software limits the user's access to information as well as the operations the user can perform. So, for example, access control software might only let users read certain files or programs, but not let them input data, and may keep them out of other files entirely.Then there are "dial back" systems that ask the user or caller for a password. The system then checks the password in a directory and calls the user back at his or her telephone number. This stops hackers who are calling from another number from gaining access to the system.Scrambling devices are also being developed by computer engineers. These devices scramble messages so that hackers can't understand them. Data can be unscrambled and used only if the scrambling key is known by the user. Scrambling is a very effective way of protecting information.Audit trail software is also now available. Audit trails monitor the use of a computer and alert owners to any attempt to enter their computer system. It is usually possible to identify any user who gained access to the system and when the access occurred, makingit possible to trace the hacker.Well, those are some of the major things that are happening at the present time in order to decrease computer crime. None of them is completely satisfactory, but together they are certainly helping. These changes, as well as the improvements that are certain to come, should influence people to stop hacking by making it less profitable and more risky.Task 10【原文】"The astronauts are returning to earth at exactly 5:24. Splashdown will be in the Pacific, 427ciles west of Hawaii."You have often heard announcements like this on television. Scientists can tell us exactly when pace-capsule will arrive on the moon, for instance, and exactly when it will return. They can calculate things like this to the nearest second. How do they do it Well, of course, they use mathematics. We can all do simple sums on paper, but we must use computers for extremely difficult calculations. Perhaps you have seen mechanical calculating machines in banks and offices. Computers aren't mechanical. They don't have wheels and gears in them. Instead, they work on electrical circuits and can do difficult calculations at tremendous speed. They can work 100 million times faster than the human mind!。

As more and more computers are used in production lines, many jobs are being taken over by computer-controlled machines. As a result, many workers are finding themselves jobless. This constitutes a threat to social security. Another problem is computer crimes. For example, some people are finding ways to break into the bank computer systems and transfer large sums of money to their own accounts. There have been many reports like this. One more negative effect of computers is that they bring about health problems.Sitting in front of computers all day undoubtedly affects people’s health.

KIDS AND COMPUTERS: DIGITAL DANGER Alison Sperry
1. There's a familiar saying, "Play is children's work." Through play, people who study child development tell us, children develop the skills and outlooks that determine the adults they will become. Playing house or school, for example, helps them "try on" the roles of Mom or Dad or teacher. Athletic activities help kids develop coordination, learn to work as part of a group, and gain confidence and a sense of fair play. Even solitary activities like reading connect children with the wider world, encouraging a sense of empathy with the greater human family.
