14．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 30million 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 crowded 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．
