Scientists are trying to make the deserts into good land again. They want to bring water to the deserts so that people can live and grow food. Even so, more and more of the earth is becoming desert all the time.

Why? Scientists think that people make deserts. People are doing bad things to the earth. Some people on the earth do not get very much rain. Yet, they still do not become deserts. This is because there are some small green plants growing there. Plants help keep water in the earth. Plants do not let the wind blow the dirt away. Without plants, the land can become a desert much more easily.

A man decides to make a farm in a very dry place. He digs in the earth and takes away the grass and plants that are already growing on the dry land.

He makes a farm. He puts plants in rows. The sun is very hot. It makes the land even drier. When the rain comes, it runs between the row of plants. It washes the good dirt away. When the wind comes, it blows between the rows of plants. It blows the good dirt away. Soon the land is not good enough for a farm any more. The man lets his animals eat all the plants on it. Now the land does not have any plants on it. The sun and wind dry the land and all of the good dirt away. Now the land is a desert.

Passage Two

For years, international swimming has been controlled by a small number of powerful nations. The U.S., Russia, Germany and Australia have produced some of the sport’s finest players and have won most of the top competitions and medals. But the results of this month’s world championships, which are being held in the Australian city of Perth, will not be so easy to predict. Since the 1996 Olympics in Atlanta, many new names and nationalities have emerged to take on the world leaders.

The 1996 Olympics should have been an opportunity for the U.S. to display its great swimming power, but instead it faced some embarrassing defeats. The surprises started on the first day of the competitions, when Fred of Belgium (比利时) set a world record in the competition for 100-metres breast-stroke (蛙泳). Never before had Belgium produced an Olympic champion swimmer. Two other countries also won swimming gold medals for the first time on the opening day. Ireland’s Michell Smith delighted her country with her first of her three gold medals. New Zealand also celebrated with Danyon Loader’s gold in the men’s 200-metre free style. Loader went on to win the 400 meters later in the competition.

By late on the second day, the U.S. team’s officials and coaches were starting to be surprised. Penny Heyns of South Africa had broken the women’s 100-metre breast-stroke record in the morning competitions before claiming gold in the final.
