Use the suggested outline and useful words and expressions to help you.3-11233-212Suggested outline and useful words and expressions3Electricity in our life
Electricity is very important in our life. ____________________ ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________3-312 We use different kinds of electrical appliances. They give us light and heat. They make our life more enjoyable and convenient. They help us work more efficiently. Electricity changes our life.
Electricity is a good servant but it is also a bad master. Electricity can be very dangerous. If you do not use electricity properly, you may get an electric shock. It may cause fires or accidents. It may hurt or even kill people.
So we should always remember to be careful with it. We should never play with it. We should save electricity whenever we can. We should make good use of electricity.3
