We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.

Water is one of the most important natural resources in the world.
Everywhere, water use is【61】. Humans already use fifty-four percent of all the【62】 water in rivers, lakes and underground. There are some estimates that this【63】will reach seventy percent by 2005.
Fresh water is necessary for life on Earth. People need water for【64】activities and to produce food. Water also is important for energy production and health of Earth's environmental systems.
The United Nations is organizing a【65】of events to increase concern【66】water issues. UN officials have【67】2003 the International Year of Fresh Water. A goal of the【68】is to build support for policies to use water more【69】.
Another goal is to get more people to use water in a way【70】will not hurt environment. The world population is more than six-thousand-million people. More than one-thousand-million【71】safe drinking water. More than two-thousand-million【72】 from diseases【73】to dirty water. And, more than two-thousand-million live without waste-treatment systems.
Water was one of the issues discussed at the UN Millennium Summit two years ago. Leaders said they would work to【74】the number of people without safe drinking water in half by 2015.
Nitin Desai directs the UN Office for Economic and Social Affairs. He says success【75】 these goals will require major changes in the ways people use water.
Next month, the World Water Forum will meet in Kyoto, Japan. Officials plan to【76】the first UN report【77】world water development. This report will examine the world's water problems.【78】it will offer suggestions on ways to meet future water demands. Experts say international reaction【79】the UN report will be an important test of the political desire to solve the water【80】.

In ancient times, man settled near rivers or on fiver banks and built up large empires.
Water is Nature’s most precious gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world rivers mean life and wealth. They feed and clothe the nations around them.
Water is also a source of energy and power. Man constructs huge dams across the river to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.
Man uses water each day. His main source of water comes from reservoirs, which in turn get their water from the rivers.
Rivers also bring down soil and minerals from the mountains and deposit them on the plains building up rich fiver deltas for raising plants and crops. Fresh water life in rivers or in lakes fed by them provide man with food.
In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.
Rivers have run on this earth long before man. Man’s future ability to live is uncertain, but rivers will flow on forever.
Rivers have been important to man ______.
A.since the last century
B.for a very long time
C.since a few hundred years ago
D.since a few years ago

The trick in food photography is to show the food looking fresh, so many dishes have
stand-ins, just as movie stars do. “When I get my lights and cameras set up, I remove the
stand-in and put in the real thing,” explains Ray Webber, who photographs food for magazine
advertisements. “Sometimes I have to brush the meat with its juices because it may have dried out
a bit. A and when I‘m shooting (拍照) something like tomatoes, I always carry water to spray them with dew just before I shoot.”
Shooting food outdoors has special problems. “I‘m always worrying about flies or worms crawling up
a glass,” Webber explains, “my worry is that someday a dog will come up from behind and run off
with the food.” Once Webber was shooting a piece of cheese outdoors and needed something to make
its color beautiful. Finally he found it: a weed with lovely blue flowers. When the shot appeared,
several people were horrified-the weed was deadly nightshade!
Just before being photographed, some meats and vegetables are _______.
A. fanned
B. dyed
C. frozen
D. made wet
A.the most important part
B.the things already done
C.the reason of moving
D.the animal in the middle
