Water is all around us. Water is in the ocean. Water is in the lakes and rivers. Water is in the air. There is
more water than land on the earth. All things must have water to live. The plants must have it. The animals must
have it. We must have it, too. We cannot live without drinking water. Sometimes, we do not have all the water
that we need. The land will dry up without water. Sometimes, there can be too much water in the land. If it rains
very, very hard, the rain water will run down the hills. It takes some of the land with it when it runs down the
hills. It is called erosion when the water takes the land away. 
      Water on the earth will never be used up. It goes from the ocean to the air to make clouds. Then, it falls
from the clouds down to the land. It runs off the land and out to the ocean again. The clouds make rain. The rain
falls onto the land. Some of it goes into the ground. Some of it washes down and goes back into the ocean.
Some water that falls down from the clouds is not rain. Some of it washes down and goes back into the ocean.
Some water that falls down from the clouds is not rain. Some of this water is snow. The snow is made of
water. Some water that is not rain or snow falls down from the clouds. Some of this water is sleet (雨夹雪).
The sleet is made of little pieces of ice. Some water that is not rain or snow or sleet falls down from the clouds.

    There have been many great inventions or things that changed the way we live. The first great invention
was the one that is still very important today--the wheel. This made it easier to carry heavy things and to
travel long distance.
    For hundreds of years after that there were few inventions that as much effect as the wheel. Then in the
early 1800s the world started to change. There was little unknown land left in the world. People didn't have
to explore much any more. They began to work instead to make life better.
    In the second half of the 19th century many great inventions were made. Among them were the camera,
the light and the radio. These all play a big part in our daily life today.
    The first part of the 20th century saw more great inventions. The helicopter in 1909, movies with sound
in 1926, the computer in 1928, jet planes in 1930. This was also a time when a new material was first made.
Nylon came out in 1935. It changed the kind of clothes people wore.
    The middle part of the 20th century brought new ways to help people get over diseases. They worked
very well. They made people healthier and allowed them to live longer. By the 1960s most people could expect
to live to be at least 60.
     By this time most people in developed countries had a very good life. Of course new inventions continued
to be made. But man now had a desire (渴望) to explore again. The earth was known to man but the stars
were not. Man began looking for ways to go into space. Russia made the first step. Then United States took
a step. Since then other countries, including China and Japan, have made their own steps into space.
    In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly
just a beginning, though. New inventions will some day allow us to do things we have never yet dreamed of.
