题目列表(包括答案和解析)

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?

 

1. Which picture means "it's not safe land"?

 

 

 

 

2. What can we learn from the passage?

  A. Swinging your arm from side to side means "yes".

  B. If the ground is dark, light smoke can't be seen.

  C. If you need some medicine, make a symbol "II".

  D. The pilots make replies with a blue light at night.

  3. What is the passage mainly about?

  A. The explanation of building signals on an island.

  B. The importance of making signals on an island.

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

D. Ways of receiving signals from a lonely island

America is a mobile society. Friendships between Americans can be close and real,yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two,perhaps a few letters for a while— then no more. If the same two people meet again by chance,even years later,they pick up the friendship. This can be quite difficult for us Chinese to understand,because friendships between us develop more slowly but then may become lifelong feelings,extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes,share their holidays,and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives,they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes,we,as hosts,will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans,however,express their welcome usually at homes,but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes,the welcome will be full,warm and real. We will find ourselves treated hospitably.

    For the Americans,it is often considered more friendly to invite a friend to their homes than to go to restaurants,except for purely business matters. So accept their hospitality at home!

1.Which of the following statements is TRUE according to the passage?  

A. Friendships between Americans usually extend deeply into their families.

B. Friendships between Americans usually last for all their lives.                  

C. Americans always show their warmth even if they are very busy.  

D. Americans will continue their friendships again even after a long break.  

2. From the last two paragraphs we can learn that when we arrive in America to visit an American friend,we will probably be ______.

A. warmly welcomed at the airport            

B. offered a ride to his home

C. treated hospitably at his home                        

D. treated to dinner in a restaurant

3.The underlined words “generous with our time” in Paragraph 3 probably mean ______.

A. strict with time          B. willing to spend time  

C. careful with time                               D. serious with time

4.A suitable title for this passage would probably be “______”.

A. Friendships between Chinese       

B. Friendships between Americans  

C. Americans’hospitality                

D. Americans’and Chinese’s views of friendships
