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?

ICE-FISHING
If you drive north from Toronto for three hours, you come to Lake Nipissing. In winter, the lake becomes ice, and thousands of Canadian fishermen travel there each weekend. They build Little houses of wood on the ice and point them in bright colours. Then they sit inside to catch the fish that swim under the ice.
Bob Marvisch has come here at this time of year for twenty-five years. 'You need clothes that are light but worm: two pairs of socks and gloves, several thin sweaters and a snow suit on top. Catching the fish is easy,' he says. 'First you break the ice and make a small round hole in it. Next you take a fishing line and put some bread on it. Then you put the line through the hole and into the water. You pull the line up when the fish eat the bread. They are between ten and twenty centimetres Long. Some people Like to eat them, but when I have caught three or four fish, I prefer to have some chocolate or other snack! Today I have caught twenty- five! It's a great sport and you can meet some nice people here!
Fishermen only use the houses on Lake Nipissing in winter.
A.Right
B.Wrong
C.Doesn't say
Rivers are one of our most important natural resources (资源). Many of the world&39;s great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
The greatest river for navigation is ___________.
A.the Amazon
B.the Nile
C.the Mekong
D.the Mississippi
From a dam, people can use the water for ___________.A.keeping the rivers clean

B.people's swimming in the river too much
C.chemicals and other materials
