We all know the dangers of fires. It’s good and necessary for a family to learn how to prepare for a fire. Here are some suggestions.
Put a smoke alarm(火警) 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.
Practise 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 start 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(毯子) 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.

口算题卡加应用题集训系列答案As we all know, language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major(主要) language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.
