　(J)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% of the earth's surface is covered with water. But about 97% of that is sea water, or salt water. Man can only drink and use the other 3%-the fresh water from rivers, lakes, underground, and other sources. And we can not even use all of that. Even worse, some of it has been made dirty.

　　 However, as things stand today, this fresh water is still enough for us. But our need for water is becoming larger and larger quickly-almost day by day. We should take steps to do with this problem now and in this way we can get away from a serious worldwide water shortage (缺少) 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 sea or runs into underground places.

　　 But even if every large city reused its water, we still would not have enough. All we'd have to do to make use 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.

　 In Canada you can find dogs, cats, horses etc. in almost every family. These are their pets. People love these pets and regard them as their good friends. Before they keep them at their houses, they take them to animal hospitals to give them needles so that they won’t carry disease(疾病).

When you visit people’s homes, they would be very glad to show you their pets and they are very proud of them. You will also find almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animals in Canada. They have a law against killing wild(野生的) animals.

One day Mrs. Wilson went shopping with Tracy and Ben. They went to the supermarket in the new shopping center.

　 “Why do you buy things here?” Tracy wanted to know. “Because they are cheaper here than at the corner store near our home,” Mrs. Wilson said.” Help me check the prices, please.”

　 The Wilsons were not rich and Mrs. Wilson was always careful with her money. She looked carefully after the prices of things. She bought lots of things in the supermarket. When they got home, the children said,“ We don’t think you saved money by going to the supermarket.”

　 “Of course I did,” Mrs. Wilson said. “Everything was cheaper there.” “We know,” the children said,“but we came home by taxi because we had too much to carry. The taxi fare was more than the money that you save! ”

　 Mrs. Wilson added everything up. Her children were right.
