Question

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?

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

D．Ways of receiving signals from a lonely island

Answer 1

【小题1】D
【小题1】C
【小题1】C

解析【小题1】细节题。关键在定位。从选项的图像来看全部是人在做什么什么动作，所以可以推测出答案在body signals这一段找。再通过小技巧-中文出现部分设题概率高，快速看到body signals部分的中文bend(弯曲)，"弯曲"存在的这一句是if you want the pilot to know that it's safe to land, 而题目要求是"it's not safe to land"，所以可以推出答案在下一句中找"if you want to say that it's not safe to land, put your arms in the air and move them to one side."所以答案选D。
　【小题1】细节题。定位找答案。A选项swinging your arm可看出还是body signals 处找答案。第二排出现：when you wave your arms up and down in a straight line, it means "yes."对比选项，选项中说"from side to side"从一边到另一边，而up and down 指的是上上下下，所以A选项不对。B选项出现关键词"light smoke"所以可以知道答案在smoke signals中找，在本段倒数第二句"if the ground is dark, light smoke can be seen more easily."所以B选项属于相反选项设计。C选项的关键词是"II"，文中表示"I need medicine."所以C选项为正确答案。D选项关键词"pilots make replies"所以答案在pilots' replies出找，本段最后一句话：at night, the pilot flashes the plane's red lights.所以D也不对。
【小题1】主旨题。A为在岛屿上建筑标志的解释，为无关选项。B所在岛上做标记的重要性，也是无关选项。C说在孤岛上发送信号的方式。D是从孤岛上接受信号的方式。某种意义上说C,D是完全相反选项。答案是C.文中叙述的都是如何通知Pilots自己在孤岛上。
