Question

【题目】 What do you do if you are in trouble 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

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 in front of you and bend your knees. If you want to say 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, the fires can be very dangerous if they get out of control. Never light a fire unless you are 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. 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 pilot flies the plane in a clockwise (顺时针方向的) 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”.

【解析】

本文是一篇说明文，主要介绍了几种在孤岛上用于联系外界、发送信息的方式，包括肢体语言、烟火信号、地对空信号以及飞行员的回答等。

【1】细节理解题。根据“If you want the pilot to know that it's safe to land, push your hands in front of you and bend your knees”可知，表示着陆安全的方式是：把手放在身体前面并弯曲膝盖。故选C。

【2】细节理解题。根据“Use large pieces of wood to make the symbols. If you can't find any wood, use earth”可知，在孤岛上你可以用木材或者泥土搭建地对空信号。故选A。

【3】细节理解题。根据“If the ground is dark, light smoke can be seen more easily”可知，如果地面是黑暗的，可以更容易地看到轻烟。故选B。

【4】主旨大意题。根据文章第一段“Surely you need to find a way to get in touch with the outside world”及全文内容可知，本文主要介绍了一些在孤岛上用于寻求帮助发送信息的方式，包括肢体语言、烟火信号、地对空信号等。故选D。
