The population of the Earth is growing faster. It is important that we look after the Earth. We need it! The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

Many textbooks are not written in the kind of English that we speak every day. In fact, sometimes the reading is so difficult that it almost seems like a foreign language. In a way, it is—the language of science. You should not expect to be able to read a difficult science passage the same way you read an interesting story; you should not expect to read it easily and all at once. Instead, you may have to read it several times through, catching on the meaning of difficult words, going back over difficult sentences, and finally putting the whole thing together. Do not be discourages if the whole passage don’t make sense to you at first. You need to pick it apart patiently until you can understand it.
These are the steps to follow when you are reading something difficult:
1. Start to read normally until you run into a sentence that doesn’t make sense to you.
2. When a sentence doesn’t make sense, go back and read it again more slowly.
3. Look for any word you don’t know in the sentence. Try to understand their meanings using word parts and context clues(上下文线索). If necessary, look them up in the dictionary.
4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do not read very much farther ahead until you understand what is being said.
5. Finally, read the sentence again. Try to put it into simpler words.
6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage once more at a usual speed. This helps you to put all ides together.
The stops sound a lot harder than they are. It is really just the normal way good readers understand anything that is difficult to read. After you have done the best you can this way, you should always feel free to ask for help from your teacher, if you have one.

German scientists say that eating a little chocolate every day may keep you away from cardiovascular(心血管的) disease. The scientists have found that chocolate, especially dark chocolate , can help you cut down 39 percent of heart disease, including taking a very small amount . However, the study advises people not to eat too much chocolate, because too much chocolate is bad for our bodies. So the scientists advise people to eat small amount of chocolate instead of sugar or high-fat snacks.
Scientists said, “Dark chocolate shows the greatest effects, milk chocolate fewer , and white chocolate no effects.” The results showed chocolate may cut down blood pressure, but they also say that further study is needed.
In the eight-year study, people’s daily diet, exercise habits, and blood pressure were studied in 19,357 persons aged 35 to 65. They found that people who are an average of 7.5 grams of chocolate a day had a very lower chance of heart disease than those who ate much less chocolate , and average of 1.7 grams a day.

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can tell how heavy the glass it. When you feel all these about the ball, you really see it.
With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pockets. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it.
The bottom of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them.
Most museums are just for looking. But today some museums have things for visitors to touch. Their signs say, “Do touch!” there you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see.
