How green are you? Do you care about protecting the environment and saving energy? We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you. Remember these three words: Reduce, reuse and recycle.REDUCE
Reduce means “use less.” Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary--- or maybe the old one will be just as good! When we do buy things, choose local produces if possible, and try not to buy too many things form abroad. It may cost a lot of money to bring them to us.
REUSE
Reuse means “use again.” Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
RECYCLE
Recycle means “change things into something else.” Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

All living things depend on the sun for their growth. Plants need light and heat to grow. They use the light from the sun to make food. But we human beings cannot make food by our own bodies from the sun. All the food we eat comes from plants in a food chain(链) . And the food chain starts with the sun . For example.
sun —→ potatoes —→ chips
sun —→ corn —→ hens —→ eggs
sun—→ wheat —→ bread
Animals need sunlight, too. Just like us, their food comes from plants in food chain, which begins with the sun. For example,
Sun → leaf → caterpilllar(毛虫) → bird
Sun → seaweed(海藻) → small fish → whale(鲸)
With the help of sunlight, we can see things during the day. Even when the sky is cloudy, the sunlight is very strong and it shines through the clouds. If there was no sun, it would be dark all the time.

The earth will perhaps be warmer by about 7 degrees centigrade. At the South Pole and the North Pole, the ice will melt (融化). The sea level (海平面) will rise by about 7meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the sunrays(紫外线). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid (酸) rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
小题1:Some scientists believe that .
