runs for skiing in the Alps. Environmentalists screamed "Disaster!" Thus warned, the Norwegians have adopted "green" advice and avoided great blots on the landscape. The speed-skating rink was built to look like an overturned ship, and placed so as not to disturb a bird sanctuary. Dug into a mountainside, the hockey arena is well concealed and energy efficient. The bobsled run is built out of wood, not metal and hidden among trees. No wonder the president of the International Olympic Committee has called these the first "Green Games."

Lillehammer's opening ceremonies featured a giant Olympic Torch burning biogas produced by rotting vegetation. During construction, builders were threatened with $7,500 fines for felling trees unnecessarily. Rare trees were carefully transplanted from hillsides. Food is being served on potato-based plates that will be fed, in turn, to pigs. Smoking has been banned outdoors as well as in, with enforcement by polite requests.

Environmentalists have declared partial victory: though Coca-Cola's plan to decorate the town with banners has been scaled back, there are still too many billboards for strict green tastes. Perhaps, but after the Games, athlete housing will be converted into vacation homes or shipped to the northlands for student dormitories. Bullets will be plucked from biathlon targets and recycled to keep the lead from poisoning ground water. And these tricks won't be forgotten. Embarrassed by environmental protests, the I. O. C. claims that green awareness is now entrenched—along with sport and culture—as a permanent dimension of the Olympic Charter.

Indeed, Sydney was successful in becoming host for the 2000 Summer Games in part on the strength of its endorsement from Greenpeace. Aspiring host cities are picking up the code. Salt Lake City, bidding for the 2002 Games, may opt to use the bobsled run that Calgary built for the '88 Games. After that, who could deny that recycling is an Olympic movement？

Which of the following countries has not paid enough attention to the "green" issues？

A．Norway.

B．France.

C．America.

D．Australia.

How has this speed of communication changed the world？ To many people, the world has become smaller. Of course, this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago, communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the oceans. In the seventeenth and eighteenth centuries, it took six weeks for news from Europe to reach the Americas. This time difference influenced people’s actions. For example, a few battles in the war of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed. They would not have died if news had come in time. In the past, communication took much more time than it does now. There was a good reason why the world seemed so much larger than it does today.

Preparing for Computer Disasters

A： Summary： When home office computers go down， many small businesses grind to a halt. Fortunately， taking steps to recover from disasters and minimize their effects is quite straightforward.

B： Fires， power surges， and floods， they&39;re all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences—melted computers， system failures， destroyed data. Yet， somehow， many of us continue to live by that old mantra of denial： "It won&39;t happen to me." Well， the truth is， at some point you&39;ll probably have to deal with at least one disaster. That&39;s just how it goes， and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason， computer disaster recovery is a blind spot for many of us. It shouldn&39;t be. Home computers contain some of our most important information， both business and personal， and making certain our data survives a disaster should be a priority. Moreover， even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate， shop， and do homework， and they&39;re even more vital to home office users. When home office computers go down， many small businesses grind to a halt. Fortunately， taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools， you can bounce back quickly and easily from minor computer disasters. And， should a major calamity strike， you can rest assured your data is safe.

Offsite Storage： Major Disasters

C： House fires and floods are among the most devastating causes of personal computer destruction. That&39;s why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives， many would still lose all their data should their house flood our burn. That&39;s because they keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but they&39;re not nearly far enough away should a serious disaster strike. So， it&39;s important to back up your system to a removable medium and to store it elsewhere.

D： There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful， and your recovery tools shouldn&39;t add to that stress. They must be dependable and intuitive， making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools， you can back up to a variety of durable disk types—from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity， a backup tool with compression capabilities is a big plus， eliminating the inconvenience of multiple disks or large uploads.

E： Once you select your tools and a suitable medium， you need to find a remote place to store your backups. The options are endless. However， no matter where you choose， be sure the site is secure， easily accessible， and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers， and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course， before using one of these services， make certain you completely trust the service provider and its security methods. Whatever you do， schedule backups regularly and store them far away from your home.

Come What May： Handling the Garden Variety Computer Crisis

F： Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash， kids "rearrange" data， adults inadvertently delete files. Although these events might not seem calamitous， they can have serious implications. So， once again， it&39;s important to be prepared. As with physical disasters， regular backups are essential. However， some of these smaller issues require a response that&39;s more nuanced than wholesale backup and restoration. To deal with less-than-total disaster， your tool set must be both powerful and agile. For example， when a small number of files are compromised， you may want to retrieve those files alone. Meanwhile， if just your settings are affected， you&39;ll want a simple way to roll back to your preferred setup. Yet， should your operating system fail， you&39;ll need a way to boot your computer and perform. large-scale recovery. Computer crises come in all shapes and sizes， and your backup and recovery tools must be flexible enough to meet each challenge.

The Right Tools for the Right Job： Gearing up for Disaster G： When disaster strikes， the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes， failed installations， and inadvertent deletions. With this powerful and convenient solution， it&39;s simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups， it&39;s also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals， it&39;s the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately， or get them both when you purchase Norton System Works.

H： Life&39;s disasters， large and small， often catch us by surprise. However， with a little planning and the right tools， you can reduce those disasters to bumps in the road. So， don&39;t wait another day. Buy a good set of disaster recovery tools， set up an automatic backup schedule， and perform. a dry run every now and again. Then， rest easy.
