Question

What do you do if you're stranded（處于困境的）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（信號）
　　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（彎曲）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(標(biāo)記). 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?

Answer 1

【小題1】D
【小題1】C
【小題1】C

解析【小題1】細節(jié)題。關(guān)鍵在定位。從選項的圖像來看全部是人在做什么什么動作，所以可以推測出答案在body signals這一段找。再通過小技巧-中文出現(xiàn)部分設(shè)題概率高，快速看到body signals部分的中文bend(彎曲)，"彎曲"存在的這一句是if you want the pilot to know that it's safe to land, 而題目要求是"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."所以答案選D。
　【小題1】細節(jié)題。定位找答案。A選項swinging your arm可看出還是body signals 處找答案。第二排出現(xiàn)：when you wave your arms up and down in a straight line, it means "yes."對比選項，選項中說"from side to side"從一邊到另一邊，而up and down 指的是上上下下，所以A選項不對。B選項出現(xiàn)關(guān)鍵詞"light smoke"所以可以知道答案在smoke signals中找，在本段倒數(shù)第二句"if the ground is dark, light smoke can be seen more easily."所以B選項屬于相反選項設(shè)計。C選項的關(guān)鍵詞是"II"，文中表示"I need medicine."所以C選項為正確答案。D選項關(guān)鍵詞"pilots make replies"所以答案在pilots' replies出找，本段最后一句話：at night, the pilot flashes the plane's red lights.所以D也不對。
【小題1】主旨題。A為在島嶼上建筑標(biāo)志的解釋，為無關(guān)選項。B所在島上做標(biāo)記的重要性，也是無關(guān)選項。C說在孤島上發(fā)送信號的方式。D是從孤島上接受信號的方式。某種意義上說C,D是完全相反選項。答案是C.文中敘述的都是如何通知Pilots自己在孤島上。
