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?

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.
I’ve always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook. Myspace---I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online business are run from one- room home offices. Others have hundreds of employee(雇员)spread across five different continent. Have you ever heard of Amazon. com, Yahoo. com?
My friends often said they got cheap textbooks off Amazon.com, or had a good deal(交易)on Steve Madden boots that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, unaware(不知道)of all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
“Why are all these packages arriving in the mail for you, Katy?” I asked her one day. Strange envelopes had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this coat?”
“Oh, only about $15in all!” She said excitedly. “Everything on eBay is on sale! It’s way better than going to the mall.”
I felt as if my entire life, there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.
