As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is necessary. Generally speaking, all living things are sure to die without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) together. They are connected in a food chain (链).

 Within a food chain, some living things are producers and some are consumers (消费者). Plants are producers because they use sunlight, soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.

There are four different kinds of consumers in the animal kingdom. A carnivore is an animal that only eats other animals. An herbivore is an animal that only eats plants. An omnivore is an animal that eats both plants and animals. A scavenger is an animal that eats dead animals.

 Look at the picture. It is an example of a food chain. The food chain shows the order that animals eat each other in a community. In the picture, you can see what animal or plant is food for another animal. See? A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. In this way, all of these animals are connected.

    School is not the safe place as it used to be. How to help students stay away from danger? There are many activities that teachers can do to teach safety in an easy way. Here are some stories from the students who have had the safety class in NO.1 Middle School.

    Milk Smith: About Sports Safety

    Once, our head teacher made up a story about sports safety. All we needed to do was to point out safe and unsafe sports behaviour in the story. From this lesson, we knew we should always do warm-up exercises before playing sports and drink some water after that.

    Amy Young: About Classroom Safety

    Yes, making up stories is a good way to learn and enjoy ourselves. We were once asked to make up a story about a boy called Naughty. He always did something naughty in the classroom and got himself into trouble. In this way, we learned to behave well and get on well with each other.

    Frank Green: About Fire Safety

    In our school, we have a fire emergency response practice(火灾应急演习) in September every year. So we know where to go if there is a fire in school. We learn to use the fire extinguisher(灭火器), too. But I don't think we should be allowed to put out the fire alone. It's too dangerous for young students like us.
