【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”

1Which picture means “it’s safe to land”

A.B.C.D.

2What can you use to build Ground-to-air signals on a lonely island?

A.Wood or earth.B.Grass and leaves.C.Wood and leaves.D.Sand or grass.

3What is the passage mainly about?

A.The explanation of body signals on an island.

B.The importance of making signals on an island.

C.Ways of living on a lonely island.

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

【题目】

The doctors and nurses wore the same suits, hats and masks, and it was difficult to tell who was who when doing an operation.To solve the problem, Rob Hackett, an anesthesiologist(麻醉师) in Sydney, Australia, had an idea to write his name on his hat. At the beginning, his workmates didn't take it seriously, even someone laughed at him, “Don’t you remember your name?”

Dr. Rob showed his thoughts on the website Bored Panda, “As we all know, doctors are a stressful job, and when facing with life and death danger, we have to race against time to try to save patients' lives. We need to create a culture that allows us to rebuild health care. We need to develop a system that reduces mistakes and errors.”

A year later, Rob had the last laugh. Surgical(外科手术)caps with names have been accepted around the world because of the following advantages:

This simple method can reduce human mistakes in medical care. Doctors found that doing this can find proper doctors and nurses in time, which greatly saves the time of communication.

The idea is to make patients feel human. The patient lies on sickbed, knowing who is doing the operation. This is also a kind of comfort which lets the patient feel less nervous.
