五、阅读理解。

Fire fighting is a serious matter. Knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but no lifts. From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury. The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room. On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement（水泥地）might end in injury. Bushes and trees can help you to have a soft landing.

56. Which of the following should NOT be used when trying to escape from a fire?

A. Windows. B. Lifts. C. Fire exits. D. Stairways.

57. How far from the ground is the second floor window?

A. About 12 feet.

B. About 6 feet.

C. About the height of an average man.

D. Nearly 10 feet.
