We all know the dangers of fires. It's good and necessary for a family to learn how to prepare for a fire，and here are some suggestions.

Put a smoke alarm in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.

Make escape plans. We should know all the ways out of the house. If there is a fire，everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.

Buy fire extinguishers（灭火器）in the house. Everyone in the family should know how to use them. Practice for a fire. We do fire practice because we teach children about fire safety. Everyone in the family should know the following fire rules：

★Don't open a hot door! The fire can grow more quickly if you open the door.

★Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.

★What will you do if your hair or clothes star to burn? First. stop! Don't run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out. Put a blanket around you to keep air away from the fire that may still be on you.

There are many possible causes for fires. A wise family is ready all the time. If there is a fire. don't forget to call 119 for help.

Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don’t understand the culture behind it.
For example, if an American boy asks his mother what’s for dinner tomorrow, she may say “I’ll play it by ear”, that means she doesn’t have plans for dinner and she will decide later. "Play by ear" used to mean playing music using the sheet music, but now people often use it when they’re not talking about music.
There’re many idioms in English. If you learn to use them, your English will be more vivid and colorful. English idioms are more common in spoken English. They can be difficult to remember sometimes. Next time when you hear somebody saying to you, "Give me a hand", you don’t necessarily stretch out your hand to him/her, but you do need to be helpful. And when the situation is out of hand, you usually can do very little to manage all that. What about a green hand? It’s not about the color of your hand! You’re a green hand when you are very new at your work and don’t have much experience. If you and your partner always work together hand in glove, you two definitely work together very well.
