Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and men need plants in order to live. This is why there are so many plants around us.
There are two kinds of plants: flowering plants and non-flowering plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruit. Non-flowering plants do not grow flowers. You can not see many non-flowering plants around you.
If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large and some are small. Most of them are green. Thanks to the plants around us, we can live on the earth.

Do you know why different animals or pests (害虫) have their special colors？Colors on them seem to be used mainly (主要地) to protect themselves.
Some birds like eating locusts (蝗虫), but birds cannot catch them easily. Why Because locusts change their colors according to the colors of crops (庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others, so they have to hide (隐藏) themselves and appear (出现) only at night.
If you study animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have colors much like the trees.
A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads out, its enemies (敌人) cannot find it, so it can escape (逃跑) at once. So it can live long, though it is not strong at all.

Some visitors to new places take pictures of animals, but other visitors hunt (打猎) and kill them. They do not kill animals for food, but because they like hunting. In many countries people can make a lot of money from animals.
Elephants die because people want ivory. Rhinoceros (犀牛) die because people want to buy their horns.
Pollution (污染) of our land, sea, rivers and sky is getting worse and worse. We are making our world a much dirtier place, so many animals cannot live in it. Pollution is bad for all of us. It’s killing animals. Sooner or later it is going to kill people too. We put new buildings on empty land and don’t think about animals. We make new roads, move rivers and cut down trees. So we are taking the natural homes of animals very fast. Where can they go In the end, the answer is often nowhere and the animals die. Animals are in danger from natural accidents. Some animals die because the weather changes and some animals are also in danger from our behaviour (行为). We can not protect animals or people from accidents or changing the weather, but we can think about our behaviors and change that!

61．例文
Dear Li Hua,
I am very excited to receive your e-mail. I am interested in your questions.
There are many rivers in our city. Ming Jiang River is one of the longest rivers. But the water in the river isn’t as clean as before. This is because people cut the trees down a lot, and some factories pour polluted water into it. As we know, trees can keep the water much cleaner. On March 12th, we often plant some trees on the hills. More and more trees are growing. Our government is trying to stop the factories pouring dirty water into it. I think the water is becoming cleaner and cleaner.
Looking forward to meeting you soon.
Yours,
Li Ming
