Dinosaurs (恐龙) from the distant past! Space battles from the distant future! There has been a revolution in special effects, and it has transformed the movies we see. The revolution began in the mid-1970s with George Lucas's Star Wars, a film that stunned (使震惊) audiences. That revolution continues to the present with dramatic changes in special effects technology. The company behind these changes is Lucas's Industrial Light ＆ Magic (ILM). And the man behind the company is Dennis Muren, who has worked with Lucas since Star Wars. Muren's interest in Special effects began very early. At the age of 6, he was photographing toy dinosaurs and spaceships. At 10, he had an 8-millimeter movie camera and was making these things move through stop motion. (Stop motion is a process in which objects are shot with a camera, moved slightly, shot again, and so on. When the shots are put together, the objects appear to move. ) Talk to Muren and you'll understand what ILM is all about; taking on new challenges. By 1989, Muren decided he had pushed the old technology as far as it would go. He saw computer graph(图像)(CG)technology as the wave of the future and took a year off the master it. With CG technology, images can be scanned into a computer for processing, for example, and many separate shots can be combined into a single image. CG technology has now reached the point, Muren says, where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel (续集), The Lost World, the stars of which were computer-generated dinosaurs, suggests that this may very well be true.

单选题Microsoft Launches Free Security Microsoft has released its free computer security package to the public. From 29 September, Windows users will be able to download the software from Microsoft's Security Essentials website. The free software gives basic protection against viruses, trojans, rootkits, and spyware. The Essentials software is Microsoft's second try at making an own-brand security package. Prior to release a beta version of Security Essentials software, code named Morro, has been available to users in the US, China, Brazil, and Israel. Microsoft said the software would be available to anyone who wanted to use it and downloading it would not involve registering with the software firm or having a limit on the amount of time it could be used for. "Consumers have told us that they want the protection of real-time security software, but that they are confused by trials and renewals and concerned about performance and as a result, too many are unprotected" said Amy Barzdukas, general manager for consumer security at Microsoft in a statement. The only restriction on use is that it has to be installed on a" genuine" Windows PC—One whose copy of its operating system has been verified by Microsoft. In the free software market Microsoft faces competition from many others including AVG. Alwil Avast, Avira Antivir and Comodo. The free software runs on Windows XP, Vista and will also be available for Windows 7 when it is released in late October. Updates will be provided automatically to those who install the software. Prior to working on Security Essentials, Microsoft offered its Windows Live One Care paid security software but this failed to win a significant user base in the highly competitive consumer market. This software was withdrawn in mid. 2009.

单选题Water Resource Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the worlds 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.

单选题Electric Backpack Backpacks are convenient. They can hold your books, your lunch, and a change of clothes leaving your hands free to do other things. Someday, if you don't mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home. Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in WoodsHole, Mass. have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions search-and-rescue operations and scientific field studies, people rely increasingly on cell phones global positioning system (GPS) receivers, night-vision goggles, and other battery powered devices to get around and do their work. The backpack's electricity-generating feature could dramatically reduce the amount of a wearer's load now devoted to spare batteries, report Rome and his colleagues in the Sept.9 science. The backpack's electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer's back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts. Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack's oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack. The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren't on the market yet, but if you do get one eventually just make sure to look both ways before crossing the street!

单选题Car Thieves Could Be Stopped Remotely Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer (使车辆不能调动的装置), and a radio signal from a control center miles away will ensure that once the thief switches the engine (51) , he will not be able to start it again. For now, such devices (52) only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars and (53) be available to ordinary cars in the UK (54) two months. The idea goes like this. A control box fitted to the car incorporates (55) miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver. (56) the car is stolen, a coded cellphone signal will tell the unit to block the vehicle's engine management system and prevent the engine (57) restarted. There are even plans for immobilizers (58) shut down vehicles on the move, though there are fears over the safety implications of such a system. In the UK an array of technical fixes is already making (59) harder for car thieves. "The pattern of vehicles crime has changed, "says Martyn Randall of Thatcham a security research organization based in Berkshire that is funded in part (60) the motor insurance industry. He says it would only take him a few minutes to (61) a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old. Modem cars are a far tougher proposition, as their engine management computer will not (62) them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this (63) achieve a 31 percent drop in vehicle-related crime since 1997. But determined criminals ore still managing to find other ways to steal cars. Often by getting hold of the owner's keys in a burglary. In 2000, 12 percent of vehicles stolen in the UK were taken using the owner's keys double the previous year's figure. Remote-controlled immobilization system would (64) a major new obstacle in the criminal's way by making such thefts pointless. A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the (65) expects.

单选题Hair Care Whether the hair is long or short, it must be regularly brushed and regularly washed. For greasy(油性的) hair, especially if the owner lives in a town, it may be necessary to wash the head every four to five days. Those with a dry hair can usually go a little longer, but this is a matter for the individual to decide. As for style, this must be studied according to what is the latest fashion and also to suit the individual at different times of her life. If a woman is not able to go to hairdresser very often, it is important that she chooses a style she can easily manage for herself, and this nearly always means that the first cut must be very standard. The same applies to permanent waving (烫发). I think that this should be carried out three or four times a year, so that the hair never gets out of hand. One thing would be remembered though, that is, whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care. Or you may use milder products. Young people who has spots or skin troubles on their face should take particular care to ensure that the hair is both clean and does not come into contact with the affected piece of skin. Hair is very difficult to keep completely clean and therefore anyone running their hands through their hair and afterwards touching their face, or letting their hair fall over their faces, might spread infection from one place to another. Good hair does a lot to the effect of a face, so if you want to look charming, please start with your hair.
