Some animals can be trained (被训练) to help humans. For example, specially trained dogs help blind people walk around the town safely. Some kinds of monkeys can be taught things too. They can learn how to help people who can’t use their arms or legs. The monkeys pick up the phone when it rings, carry shopping bags and do housework.

In the wild, animals and humans are not usually friends, but there are a few interesting examples where they can work together. In Africa, the honeyguide bird works with humans to find food. The bird likes to eat the grubs-a type of insect that lives inside a beehive (蜂窝). It knows how to find beehives but it can’t open them and get the grubs. People like to eat honey, but they aren’t very good at finding beehives, so the bird and the people help each other. The bird flies to a beehive and people follow it. When the people open the beehive and take the honey, they give the grubs to the bird.

In Laguna in the south of Brazil, fishermen and dolphins work as a team. The ocean isn’t very clean, so the fishermen can’t see the fish. However, dolphins can find them easily by using sounds. When the dolphins find a large group of fish, they make a noise to tell the fishermen. Then the dolphins push the fish toward the beach. The fishermen wait in the water near the beach and catch a lot of fish in their nets. The fishermen’s nets make it easier for the dolphins to catch fish, too. In Laguna, fishermen and dolphins have been working together for many years. The fishermen teach their children how to work with the dolphins. The dolphins must be happy to help because they teach their babies how to work with the humans!

Children are often interested in fire. They like to play w1． matches. If they are not c2．, they start fires at home. They hide under beds or just cry with fear instead of running to safety. 20%-25% of all fire deaths are children, so all children should learn about the danger of fire.

Most fires start out s3．, but after a few minutes they can be big. The most important thing to do is to hide all matches. Of course, young children should never be left alone in the home. Even if they don't play with fire, they may start a fire by trying to cook in the wrong way.

It’s also important for children to learn how to crawl (爬) on the floor and below the smoke to g4． out of the house and ask for help from another place. Don’t try to put out the fire yourself. Call 119 and tell where you are and w5． is on fire.

Remember not to go back into the home for your pets or your favourite t6．. Firefighters will do this. Don’t use the lift. Always use the stairs. The lift may go wrong and keep you inside.

It is very important to stay healthy. I have a neighbor. She is an old lady. She can do all the housework, _______ newspapers, watch TV and search on the Internet to learn something new. I often see her do taijiquan in the morning and dance in the evening. She is over seventy _______ she looks young and beautiful. Last week a reporter from a magazine interviewed her and asked how she kept so young and healthy. She replied with a smile:

I have a secret of staying young and healthy. It is quite _______. Keep your mind active, take an interest in the world around you, and learn at least one new thing every day. Try to do different kinds of housework and do sports as _______ you can. Don't think you are too old to go back to school. I know a man who entered a medical college when he was 70 years old. He studied there for 6 years and now he is a doctor. Another man went to a tennis school at the age of 71 and now he is good at _______ tennis. Some people may say staying young is easy only for those who live in the future. In fact, no matter how old you are, you can make it.

Please tell the story to your family. It would be a good start to _______ the Lady's example. I hope all people will stay young and healthy.

What do you, the trees and animals have in common(共同点)? You all 1． water. Water is the “life blood” of our earth. It is in every living thing. Without water, your body would stop 2．. It is in the air. It runs through 3． and valleys. It forms lakes and oceans. Water is everywhere.

Nature has a great water system. Rainwater finds its way to 4． and rivers. Rivers lead to the oceans. At the mouths of the rivers, fresh water joins the salt water of the oceans. Here at the mouth of a river there is much important plant and animal life. However 5． destroys the life, so we have to clean our streams and rivers. Man has to work 6． nature-not against it.
