People know the dangers of fires. It’s good for a family to learn how to prepare for a fire. 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. They 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. They do fire practice because they teach children about fire safety. Everyone in the family should know the following fire rules:

① Don’t open a hot door! The fire can grow more quickly if you open the door. ② Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises. ③ 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 (打滚)! Turning over and over will make the fire go out. Put a blanket around you to keep air away from the fire that still be on you.

“China is always well protected by the bravest of them” former (从前的) US secretary of state Henry Kissinger once wrote. Indeed, in the fight against the novel coronavirus, it is medical workers who are risking their lives on the frontlines of the epidemic (流行病).

To help them know each other, they write their names on their clothing. To save time going to the bathroom, they choose to wear diapers (纸尿裤). The paper reported.

Many doctors and nurses were infected (感染) during the earliest period of the epidemic because of knowing less about the virus, as well as shortage (短缺) of medical supplies (供应). Some of them were treated, got well and went back to work. Some of them unluckily lost their lives.
