　　Plants are very important living things. Life couldn't go on if there were no plants. This is because plants can make food from the air, water or sunlight. Animals and man can't make food from air, water or sunlight. Animals get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. Therefore, animals and man need plants in order to live. This is why we find that there are so many plants around us.

　　If you look carefully at the plants around you, you will find that there are many types of plants. Some are large while others are small. Most plants are green.

　　There are two main types of plants：flowering plants and non－flowering plants. Flowering plants have roots, stems and leaves, flowers and fruits. Almost all the trees around us are flowering plants. You probably recognize some plants from their flowers and fruits.

　　Non－flowering plants don't grow flowers. They include coniferous trees, mosses, and liverworts. You can' t see many non－flowering plants around you.

The World's Water Shortage

　　The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70 percent（百分比）of the earth's surface is covered with water. But about 97 percent of this huge amount is sea water, or salt water. Man can only drink and use the other 3 percent--the fresh water from rivers, lakes, underground, and other sources（资源）. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers（冰川）. Even worse, some of it has been polluted.

　　However, as things stand today, this small amount of fresh water is still enough for us. But our need for water is increasing（增加）rapidly--almost day by day. Only if we take steps to deal with this problem now can we avoid（避免）a severe（严重）worldwide water shortage later on.

　　We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing it.

　　Today in most large cities, water is used only once and then sent out into a sewer system（下水道）. From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe used water to a purifying（净化）plant. There it can be treated with chemicals so that it can be used again, just as if it were fresh from a spring.

　　But even if every large city purified and reused its water, we still would not have enough. All we'd have to do to make use of the vast reserves（贮备）of sea water in the world is to remove the salt.

　　If we take these steps we'll be in no danger of drying up.

　　Jacks is the name of a game that is a quite popular(流行) with children. To play jacks, you will need a small rubber ball and ten small metal objects (金属物) called jacks.

　　The rulers for this game are very simple (简单). When the game begins, you put the jacks on the floor or ground in front of you. Toss the ball up (but not too high), pick up one jack, and then catch the ball. Keep the jack in your hand and then go on picking up the other jacks one at a time. You lose your turn if you do not catch the ball, if you do not pick up a jack, or if you drop any jacks from your hand.

　　When you finish all ten jacks, you now try to do the same thing again but with two jacks at one time. This is more difficult of course. You lose your turn if you make any of the other three mistakes or if you do not pick up two jacks each time!
