What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.

Escaping from a fire is a serious matter. Knowing what to do during a fire can save your life. It’s important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not elevators.

From the lower floors of the buildings, escaping through windows is possible. Learn the best way of leaving by windows with the least chance of serious injury.

The second floor window is usually not very high from the ground. Of course, it is safer to jump a short way than to stay in a burning building.

Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may come into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may get into the room.

On a second or third floor, the best windows for escape are those that open onto a roof . From the roof a person can drop to the ground more safely. Dropping onto hard ground might end in injury. But shes and grass can help to break a fall.

Childhood is a time of fun and games. Many people still remember when they were young, they often played games like hide-and-seek and chess. Playing teaches children how to get along with others, and it also helps to exercise the mind and body. However, children today spent most of their playing time in front of the computer, playing video games.

A recent survey found that in the US children between 8 and 12 spent at least 13 hours a week playing video games or “gaming”. Boys of this age spend even more time, almost 16 hours a week. Although some people will say that gaming is helpful, it brings many problems as well.

One big problem is that kids who spend most of their time on games might have difficulty communicating with real people. They might have trouble sharing and resolving problems because they do not practice these skills when sitting alone at a computer.

Another problem is about health. Game players usually sit for hours without doing any exercise. And they might not eat healthily. As a result, they might be out of shape.

Next, game players might have trouble with their lessons. Many of them spend more time playing games than working on their homework. In the end, _______.

Finally, it is always possible that the gamers become addicted(成瘾). Some people play four or five hours a day or even all day. This happened to a 28-year-old Korean man. He spent about 50 hours playing an online game without sleeping or eating well. He died while gaming!

This is one example of the dangers of video gaming. It tells us that video gaming, like everything else, should not be done too much. A few hours a week should not hurt, but several hours a day just might be dangerous to your health.
