At the shopping mall, you probably think about spending, not saving. Think about all the lights that keep the mall bright. Think about all the water faucets in the toilet. Think about all the air conditioning in summer. Saving energy is a hot topic for such a big place!
　　Many things at the mall use energy. Electric lights, infrared faucets and air-conditioners need electricity to work. One way to save energy is by keeping lights clean. More and more dust and dirt make the lights less bright. When  malls keep lights clean, they can use fewer lights and keep the area just as bright ,Using fewer lights means using less energy.
You step up to the  water faucet. The water starts to flow. You don't have to touch a thing. Why do malls have such fancy faucets?. The answer is simple. They save water. Sometimes people forget to turn the water off after they wash. Infrared faucets turn themselves off.

【小题1】________is a hot topic for a big mall.

India is the home of tigers. Every year many people are killed by tigers. The tiger, however, doesn’t always eat men. It likes wild animals better. It is only when the tiger is old enough or wounded (受伤的) that it eats men. But when it tastes the meat of men, it will go on killing men for food. When a man-eater like this is discovered (发现)people are very afraid. They have to stop working in the fields.
There are many ways to put an end to such dangerous animals. One way is that some men with long guns (枪) ride on elephants while other men drive the tiger towards them.
For a hunter another way is to sit in a tree near the place where a tiger has eaten somebody. If the tiger returns for another meal, the hunter will kill it in the hiding place. A goat may be tied to the tree for the tiger to kill.
The most dangerous way is to hunt a tiger on foot. But the man must be brave and can shoot well or he would be killed by the tiger.

Yesterday and Today

Life in the twenty-first century will be different from life today. Between then and now many changes will take place, but what will the changes be?

The population is growing fast. There will be many people in the world and most of them will live longer than people live now.

Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in schools then.

People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruit and vegetables. Maybe people will be healthier.

Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.

The tree house

Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.

The Lizard house

Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.

Meals at home

This design is perhaps as much about the future of food production as architecture (建筑风格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.

Learning from the past

Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.

How often one hears children wishing they were grown-ups, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What’s more, life is always giving new things to the child--- things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is repeatedly being told not do something or being punished for what he has wrongly done.

When a young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he worked hard, keeps out of trouble and has good health, he can have the greatest happiness of building up for himself his own position in society.
