What do you do when you are in trouble on a lonely island? Surely you need to a way to get in touch with the outside world. Your best of doing this is to draw the attention of a passing plane. The smoke from a fire can be seen from far away, it is a good way to attract attention. If the weather is dry, it's to start a fire. But remember that fires can be very dangerous if they are out of control. make a fire unless you're sure that it can't spread. If the ground is dark, smoke can be seen more easily. Green grass and leaves produce white smoke. It's a good idea to make some , too. For example, 'F' means 'I need food and water'', 'IF'   'I need medicine' and “I” for 'I am too hurt to move from here'. These are useful symbols. Use large pieces of wood to make them. If you find any wood, use earth. You can be found more easily in this way. 小题1: A. give            B. find            C. show 小题2: A. place           B. service          C. chance 小题3: A. so             B. but             C. or 小题4: A. hard         B. easy           C. impossible 小题5: A.
