  Water is 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 hills 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. Tile clouds in the air are made up of water. Sometimes the water falls down from the clouds. It makes 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 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. Some of this water is hail(冰雹). The hail is made of ice halls!

   Plants are very important  1    things. Life could not go  2    if there were no plants. This is because plants can make food from air, water and sunlight. But animals and man cannot  3    so. Animals get their food by eating plants and  4    animals. Man gets its food by eating plants and animals too.  5    animals and man  6    plants in order to  7    . This is why we find that there are so many plants around us.

   If you look  8    at the plants around you, you will find that there are many types of plants. Some plants are large,  9    others are small.  10    plants are green. There are two sorts(种类)of plants: flowering plants and non-flowering(不开花的)plants.

   Flowering plants have roots(根),stems(茎),leaves, flowers and fruits(果子).  11    all the trees around us are flowering plants. Flowering plants  12    make seeds(种子). The sends  13 by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds  14    .  15    example of a fruit  16    seeds is banana fruit.

   Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are small. Some spores are  17    small and  18    that they can float(漂浮) 19     the air. We may say that spores are quite different from seeds. When these spores  20    on wet and shady(阴凉的)places, they usually grow into plants.
