Unlike other movements-–for example, the introduction of the cassette tape or the CD—the MP3 movement started not with the industry itself but with a huge audience of music lovers on the Internet. The MP3 format for digital music has had, and will continue to have, a huge impact on how people collect, listen to and distribute music.If you have ever wondered how MP3 files work, or if you have heard about MP3 files and wondered how to use them yourself, then this article is for you!The MP3 FormatThe MP3 format is a compression system for music. The MP3 format helps reduce the number of bytes in a song without hurting the quality of the song’s sound. The goal of the MP3 format is to compress a CD-quality song by a factor of 10 to 14 without noticeably affecting the CD-quality sound. With MP3, a 32-megabyte (MB) song on a CD compresses down to about 3 MB. This lets you download a song in minutes rather than hours, and store hundreds of songs on your computer’s hard disk without taking up that much space.From this description, you can see that MP3 is nothing magical. It is simply a file format that compresses a song into a smaller size so it is easier to move around on the Internet and store.Using the MP3 FormatKnowing about the MP3 format isn’t half as interesting as using it. The MP3 movement—consisting of the MP3 format and the Web’s ability to advertise and distribute MP3 files—has done several things for music:* It has made it easy for anyone to distribute music at nearly no cost (or for free).* It has made it easy for anyone to find music and access it instantly.* It has taught people a great deal about manipulating sound on a computer.That third one was accidental but important. A big part of the MP3 movement is the fact that it has brought an incredible array of powerful tools to desktop computers and given people a reason to learn how they work. Because of these tools, it is now extremely easy for you to:* Download an MP3 file from a Web site and play it* Rip a song from a music CD and play it directly or encode it as an MP3 file* Record a song yourself, convert it to an MP3 file and make it available to the world* Convert MP3 files into CD files and create your own audio CDs from MP3 file on the Web* Rip songs off of various music CDs and recombine them into your own custom CDs* Store hundreds of MP3 files on data CDs* Load MP3 files into tiny portable players and listen to them wherever you goTo do all of these amazing things, all you need is a computer with a sound card and speakers, an Internet connection, a CD-R drive to create CDs and an MP3 player. If you simply want to download MP3 files from the Web and listen to them , then all you need is a computer with a sound card and speakers and an Internet connection—things you probably already have! Downloading and ListeningIf you would like to download and then listen to MP3 files on your computer, then you need:* A computer* A sound card and speakers for the computer (If your computer has speakers, it has a sound card.)* An Internet connection (If you are browsing the Web to read this article, then you have an Internet connection and it is working fine.)* An MP3 player (a software application you can download from the Web in 10 minutes) If you have recently purchased a new computer, chances are it already has software that can play MP3 files installed on its hard disk. The easiest way to find out if you already have an MP3 player installed is to download an MP3 file and try to double-click on it. If it plays, you are set. If not, you need to download a player, which is very easy to do.There are thousands of sites on the Web where you can download MP3 files.Go to one of these sites, find a song and download it to your hard disk (most MP3 sites let you either listen to the song as a streaming file or download it–-you want to download). Most songs range between 2 and 4 MB, so it will take 10 to 15 minutes unless you have a high-speed Internet connection. Once the song has finished downloading, try to double-click on the file and see what happens. If your computer plays it, then you are set. You are now ready to begin collecting MP3 files and saving them on your computer. Many people have hundreds of songs they have collected, and they create jukebox-like play-lists so that their computer can play them all day long!Taking the Files with YouMany people who start collecting MP3 files find that they want to listen to them in all kinds of places. Small, portable MP3 players answer this need. These players are like portable cassette players except that they are smaller.These players plug into your computer’s parallel, FireWire or USB port to transfer the data, and a software application lets you transfer your MP3s into the player by simply dragging the files. See How MP3 Players Work for details.Creating Your OwnIf you have a CD collection and would like to convert songs from your CDs into MP3 files you can use ripper and encoder software to do just that. A ripper copies the song’s file from the CD onto your hard disk. The encoder compresses the song into the MP3 format. By encoding songs, you can play them on your computer or take them with you on your MP3 player.26. The MP3 format for digital music has a huge impact on how people collect, listen to anddistribute music.27. The MP3 format is a compression system for movie.28. MP3 is a magical file format that compresses a song into a smaller size.29. The MP3 movement refers to MP3 format.30. The MP3 movement has made it easy for anyone to distribute music at nearly no cost (or forfree).31. It is difficult for you to download an MP3 file from a Web site and play it.32. If you have recently purchased a new computer, chances are it already has software that canplay MP3 files installed on its hard disk.33. There are literally thousands of sites on the Web where you can download MP3 files.34. Small, portable MP3 players are like portable cassette players in that both use batteries.35. You can use ripper and encoder software to convert songs from MP3 files into your CDs.Section B Reading in DepthDirections: There are 3 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C),and D). You should decide on the best choice and mark the corresponding letter onthe Answer Sheet with a single line through the center.Passage OneQuestions 36 to 40 are based on the following passage.Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.But that doesn’t have to be the outcome. Water shortages do not have to trouble the world ––if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.36. What is the real cause of the potential water crisis?A) Only half of the world’s water can be used.B) The world population is increasing faster and faster.C) Half of the world’s water resources have been seriously polluted.D) Humanity has not placed sufficient value on water resources.37.“But that doesn’t have to be the outcome”（1st sentence in Para. 2）means ______.A) The problem has been exaggeratedB) The problem will not necessarily occurC) The problem has been ignoredD) The problem will not come as expected38. According to the author, water price should ______.A) be reduced to the minimum B) stimulate domestic demandC) correspond to its real value D) take into account the occurrences of droughts39. The author says that in some hot and dry areas it is advisable to ______.A) build big lakes to store waterB) construct big pumping stationsC) build small and cheap irrigation systemD) channel water from nearby rivers to cropland40. In order to raise the efficiency of the water supply, measures should be taken to ______.A)guarantee full protection of the environmentB)centralize the management of water resourcesC)increase the sense of responsibility of agencies at all levelsD)encourage local and regional control of water resourcesPassage TwoQuestions 41 to 45 are based on the following passage.Tracking down cyber-criminals（网络罪犯）who steal credit card numbers, transfer money from other people’s accounts, or e-mail viruses around the world takes a knowledge of the technology used to commit the crimes. Instead of using fingerprints or following suspects, government agents go through the computer system to the cyber-criminals.One such investigation led to the arrest of the man accused of sending the extremely dangerous Melissa virus, a computer virus that destroyed files in computers around the world in the spring of 1999. The agents received help from online service technicians, software experts, and a computer-science student. All helped to trace the complex pathways of the virus back to the telephone line and computer of the man who released it.In another case, agents worked for two years to catch a cyber-criminal who was, among other offenses, stealing credit card number. Agents found him by tracing a path from a computer he broke into to the mobile telephone he had used, which led to his address—and arrest.The government agents are also working to block cyber-criminals who could cut off power and confuse telephone companies. ―Think of the consequences if the power went out for a week –-not in just one town or city but down the whole East Coast,‖ says Michael Vatis, an FBI agent. From TVs to hospital equipment, all would fail.Makaveli and TooShort were arrested for the charges of breaking into computers. Theywere given probation（缓刑）, required to perform community services, and prevented from having home computers with modems. Punishment for adults can be more severe and usually includes some jail time.Most people use their computers legally. For the few who don’t, however, cyber-police and better security systems will make it harder for cyber-criminals to get away with their crimes.41. Which of the following can help government agents catch cyber-criminals?A) Numbers, symbols and letters.B) Credit card numbers.C) Suspects’ fingerprints.D) The technology used to commit the crimes.42. Why was the Melissa virus extremely dangerous?A) Technicians, experts, and a student were involved.B) Because it destroyed computer files on the world scale.C) Telephone companies were confused.D) The power in the government building was cut off.43. Which of the following is NOT mentioned as a way of punishing the cyber-criminals?A) Being put into prison.B) Sentenced to death.C) Not being allowed to own computers with modems at home.D) Doing something for the community.44. ―Get away with their crimes‖ (in the last paragraph) probably means ______.A) Go away after committing a crime. B) Committing another crime.C) Avoid being punished. D) None of the above.45. What can be inferred from the last paragraph?A) It’s impossible to catch all cyber-criminals even with advanced security systems.B) Police are always smarter than criminals.C) The author complains about cyber-crimes.D) The author commands that hackers must stop committing cyber-crimes.Passage ThreeQuestions 46 to 50 are based on the following passageDeath comes quickly in the mountains. Each winter holidaymakers are caught unaware as they happily ski away from the fixed runs, little realizing that a small avalanche（雪崩）can send them crashing in a bone-breaking fall down the slope and leave them buried under tons of crisp white snow. There are lots of theories about how to avoid disaster when hit by an avalanche. Practice is normally less cheerful.The snow in the Salzburg of Austria where a recent disaster took place was typical avalanche material. For several days before the incident I had skied locally. Early winter snow was wearing thin and covered with ice. On top of that, new warmer flakes were gently falling to produce a dangerous carpet. To the skier who enjoys unmarked slopes it is tempting stuff, deep new powder snow on a hard base—the skiing that dreams are made of and sometimes nightmares.Snow falls in sections like a cake. Different sections will have different densities because of the temperatures at the time of the fall and in the weeks afterwards. Problems come when any particular section is too thick and not sticking to the section beneath. The snow of the past few weeks had been falling in rather higher temperature than those of December and early January. The result of these conditions is that even a slight increase in the temperature sends a thin stream of water between the new snow and the old. Then the new snow simply slides off the mountain.Such slides are not unexpected. Local citizens know the slopes which tend to avalanche and the weather in which such slides are likely. Traps are set to catch the snow or prevent it slipping; bombs are placed and exploded from time to time to set off small avalanches before a big one has time to build up; and, above all, skiers are warned not to ski in danger areas.In spite of this avalanches happen in unexpected areas and, of course, skiers ignore the warnings. The one comfort to recreational skiers, however, is that avalanche incidents on the marked ski slopes are quite rare. No ski resort wants the image of being a death trap.46. Each winter holidaymakers in the mountains come face to face with death because ______.A) They fail to realize how dangerous avalanches can beB) They are not experienced enough at skiing on the fixed runsC) They are trying to avoid areas where avalanches happenD) They ski great distances down the mountainsides47. According to the writer, skiing conditions in the Salzburg before the accident happened were______.A) Suitable only for skiing locallyB) Typical of conditions resulting in avalanchesC) Very badD) Perfect for the inexperienced skier48. It would appear from the text that avalanches are brought about because ______.A) There is a slight fall in the temperatureB) A particular section of snow is not thick enoughC) Heavy snowfalls turn into rainD) The ice between different sections of snow melts49. In areas where avalanches are known to happen ______.A) Local residents do nothing but stay indoorsB) Measures are taken to prevent serious avalanchesC) Skiers are told how to ski in dangerous areasD) Local residents try to prevent small avalanches50. Although accidents do happen, skiers will be reasonably safe if ______.A) They ski slowlyB) They stay on the officially approved slopesC) They ski only for pleasureD) They choose less crowded ski slopePart III Cloze (10%)Directions:There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C), and D). You should choose the ONE that best fits intothe passage. Then mark the corresponding letter on the Answer Sheet with asingle line through the center.Ecology is the science of how living creatures and plants exist together and depend on each other and on the local environment. Where an environment is undisturbed, the ecology of an area is __51 balance, but if a creature is exterminated（灭绝）or an alien species（外来物种）52 , then the balance of nature will be 53 .Man is a part of the 54 and has done more to upset the ecology during 55 short span on earth than 56 other living creature. He has done this by his ignorance, his 57 , his thoughtless foolishness and his uncontrolled wastefulness. He has poisoned the 58 and polluted both land and water. He has wasted the earth’s natural resources with no 59 for the future, and has thought out the most devastating (毁灭的) ways of killing his fellow men and every other sort of life at the same time.Since man has done so much 60 , it is 61 to man to try to put matters right—if it is not already too 62 . If there is to be any remedy (治疗方法) for our ills, that remedy ultimately lies in the hands of the 63 , and the sooner they start doing something about it, the _64 .One of the main 65 of the earth’s troubles is that the world is overpopulated and that this overpopulation is growing 66 an ever-increasing rate. At the same time we are 67__ up our natural resources -–fuels and mineral ores—at an ever-increasing speed with no hope of replacing them. For many years the earth has been unable to 68 enough food for these rapidly expanding populations and the situation has been steadily deteriorating (恶化) 69 the fertility（肥沃）of some of our richest soils will be lost, and vast areas that were 70 fertile lands will turn into barren（贫瘠的）deserts.51.
