They will telephone the police and complain about it       the noise     .

What do you do if you're stranded（处于困境的）on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

　　Body signals（信号）

　　Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend（弯曲）your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

　　Smoke signals

　　The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

　　Ground-to-air signals

　　It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:

　　F "I need food and water."

　　II "I need medicine."

　　I "I am badly hurt."

　　X" I am unable to move from here."

　　Pilots' replies

　　If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)

However, there is no signal which means "message not received". Why not?

1. Which picture means "it's not safe land"?

2. What can we learn from the passage?

　　A. Swinging your arm from side to side means "yes".

　　B. If the ground is dark, light smoke can't be seen.

　　C. If you need some medicine, make a symbol "II".

　　D. The pilots make replies with a blue light at night.

　　3. What is the passage mainly about?

　　A. The explanation of building signals on an island.

　　B. The importance of making signals on an island.

　　C. Ways of sending out signals on a lonely island.

D. Ways of receiving signals from a lonely island

Mary’s dime（一毛钱）

It was Sunday afternoon. I decided to clean up the room nicely so that my parents would feel   1  when they returned from a long ride! Then, I sat in the room, having nothing to do.

　　 What else could I do? Then, with no reason, I suddenly  2  the pale face of that little beggar(乞丐) girl. I could see the glad light   3  her eyes when I put the dime in her little dirty hand.

　　  How much I  4  that dime, too! Grandpa gave it to me a whole month ago, and I had kept it ever since in my red box upstairs, but those sugar apples looked so attractive, and were so   5  — only a dime a piece — that I wanted to have one.

　　  I could imagine the little girl stood there in front of the  6  in her old dirty dress, looking at the   7  that were put all in a row in the window. I wonder what I should say, “Little girl, what do you want?” I gently asked. She felt   8  and looked straight at me, just as if（似乎）nobody had spoken so   9  to her before. She realized what I had meant, so she said seriously and sadly. “I was thinking how good one of those delicious hamburgers would  10 . I haven’t had anything to eat today.”

　　 Now I thought to myself, “Mary Williams, you have had a good breakfast and a good lunch today,   11  this poor girl has not had a mouthful yet. You can give her your  12 . She needs it a great deal more than you do.”

　　 I could not run away from that little girl’s sad,  13  look — so I dropped the dime right into her hand. How  14  the girl was! I am so glad I gave her the dime,  15  I had to go without the apple lying there in the window.
