Fire is very useful,It can give light and keep us warm.we can cook food with fire,sometimes it can protect us from wild animals.But if sometimes it can be very dangerous,we must be careful when we use fire.we mustn't drop the burning cigerette ends everywhere,we must remember to put out the barbecue fire when we leave,we mustn't play with fire,we mustn't play with matches.Fire is very useful and harmful,so we must be careful with it.
