Some English words have more than one meaning. These are called multi-meaning words.

    Multi-meaning words have the same pronunciation with different meanings. For example, let's look at the word "ball". You could have a "ball" which means you would have a good time. You could toss a "ball" which means you throw an object. You could be on the "ball" which means you know what is happening. You could go to a "ball" which means a dance.

    ______Take the word "can". You "can" ride a bike which means you are able to ride a bike. You have a "can" of soup which means the soup is in a round-shaped holder. You can do the "can-can" which is a dance from the 1920s. And you might get "canned" if you do a poor job at work, which means you might lose your job.

    How about "fly"? You can "fly" an airplane or you can hit a "fly" that is on your food in your house. Or, you can "fly by the seat of your pants" which means you don't make a plan before taking an action. And, you know that the "fly" of a zipper (拉链) is the top part of the zipper.

    There are hundreds of words that are multi-meaning words. The word "set" has more meanings than any other word in the English language. When you have time, why don't you try to think of all the ways the word "set" is used?

    If you look at the title of this book Can a Fly, Fly?... you know that the answer is "Yes" because you have seen an insect named a "fly" go up in the air and move around through the air…which is what "fly" means. Can a Fly, Fly? Of course, it can!

      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 is important to know the ways you can use and show them to everyone in the family，such as stairways(楼梯)and fire escapes，but not lifts．

       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(受伤)．

      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 be drawn into the room．Keep your head low at the window to be sure you get fresh air rather than smoke that may leak(渗)into the room．

      On a second or third floor，the best window 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．Bushes(灌木丛)and grass can help to break a fall(使势头减弱)．
