We are lucky to live in a rich country where we have many things. However, most of us usually1 some things.

Electricity(电) is one thing that we waste 2. Lights, TVs, 3 and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It 4 less than a second to do it. Anyway, not wasting electricity saves money, because we do not have to 5 the electricity we do not use.

The second thing that we often waste is water. Fresh water is precious(宝贵的) ， 6it shouldn't be wasted. It is only a simple matter of turning off a tap. I am sure 7 can do this easily if he wants to.

8 big waste is food. My mother 9 cook so much food that much of it was thrown away. I told her we had wasted so 10 food. She thought I was right and now cooks 11what we can eat.

All over the world, people enjoy sports. Sports are good for people's health. Many people like to watch others play games. They buy tickets or turn on their TV sets to watch in front of them.

Sports change with the seasons. People play different games in different seasons. Sometimes they play inside the room. Sometimes they play outside. We can find sports here and there. Some sports are rather interesting and people everywhere like them. Football, for example, is very popular in the world. People from different countries cannot understand each other, but after a game they often become very friendly to each other.

More and more people around the world are joining in dangerous sports. Some people climbed the highest mountains; some traveled into unknown parts of the world; some sailed small boats across the largest sea. Now some people begin to look for new excitement.

Bungee jumping (蹦极) and motorcycle racing (摩托车赛) are quite dangerous sports. Bungee jumping only lasts for a few minutes or even seconds. You jump from a high place, about 200 meters above the ground, and there is a rubber band (橡胶带子) tied to your legs. When you jump down, the rubber band pulls you up. About 2,000,000 people around the world have tried bungee jumping.

Why do people join in these dangerous sports? Some scientists say that it is because modern life has become safe and it is not interesting. In the past, people lived in danger. They had to go out and look for food, and life was like a fight but was interesting.

Many people think that there is little excitement in life. They live and work in safe places, buy food in shops, and there are doctors and hospitals to look after them if they become ill.
