Passage 1

The Information Highway is the road that links computer users to a large number of on-line services: the Web, e-mail, and software, to mention just a few. Not long ago, the Information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.

Passage 2

Want to know more about global warming and how you can help prevent it? Doctor Herman Friedman, who is considered a leading expert on the subject, will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching (变白) of the Great Barrier Reef, which came into the public eye in 2002, is his latest interest. Signed copies of his colorful book, which was published just last month, will be on sale after his talk.

Mapping Your World

Different forms of maps are appearing. They allow independent travelers to get local knowledge of places they are visting, from the official to the unusual. Meanwhile, hi-tech developments are creating new ways for us to map the world. Here are two of our favorites:

Green Maps

Green Maps allows people to share with the world their knowledge of environmentally friendly plaees and attractions in the local areas. Users add information with a set of icons (图标), making it easy to read any map, whatever the　 nationalities of those who produce it. At present there are over five hundred map projects being developed in 54 countries. Green Maps’ advertised idea is “think global, map local”. It is a wonderful way of gaining all sorts of information of a place, ranning from community gardens to good places of birdwatching.

Green Maps is not specifically intended for travelers. Not all of its maps are online, so it may be necessary for some users to communicate with producers through the Green Maps website.

Maps Mashups

Many people use online maps developed by Google, but not many know about the mashups of them. Working in a similar way to Green Maps, Maps Mashups allows people to add icons of their own to exsiting maps to express a certain topic. The mashups is so called because it combines all the knowledge you could ever need. It ranges from the extremely useful, such as where all the World. Heritage Site are, to the most bizarre (古怪的)，such as where America’s drunkest cities are. With the mashups added to the basic Google Maps, a multi-layered (多层的) map can be created.
