Betty needed some new clothes. Mrs. Jones took her to the department store. They went to the children's department. A saleswoman came up to them.

　　“Can I help you?” she asked.

　　“Yes,” Mrs. Jones said. “My daughter needs a new blouse.”

　　“What size is she?” the saleswoman asked.

　　“She was a size six last year, but she's bigger now.”

　　“We'll try a size seven,” the saleswoman said.

　　Betty tried on several blouses. She didn't like any of them. Some were too big. Some were too small. Then she tried on one that was the right size.

　　“That one looks right,” her mother said.

　　“No, Mom,” Betty said. “It's too heavy. I'll be hot.”

　　At last Betty found one she liked. “This is just right,” she said. “It's not too heavy. It's not too thin. I like the color.”

　　“Good,” her mother said. She turned to the saleswoman. “How much is this blouse?” she asked.

　　“One hundred dollars,” the saleswoman said.

　　“That's much too expensive!” Mrs. Jones said.

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?
