Many people have talked about whether or not computing machines can think. Can they or can’t they?

Almost certainly, a machine can do any work in thinking that a person can do—if the correct way for doing the thinking work can be told exactly. Besides, many programs have been made to direct machines so that they work in very clever ways. Machines have been taught to play chess and to learn from what happens in the games so as to make their play better and better. Machines can beat many persons who play chess. Machines can translate from one language to another. They can prove statements in geometry（幾何） as taught in school. Machines can notice printed marks on paper, so that a person is no longer needed to look at the marks.

Computers can be used in many ways, such as business, science, industry, and government. Computers study oilfield examinations made by airplanes； they keep record of oil sales； they study the working condition of the machines； they help in planning and producing oil； and much more.

If people cannot tell exactly the correct way to do certain work in thinking, it is still a question how much of this work a machine can do. Suppose a person is “teaching” the machine and telling the machine “yes” when the machine is right, and “no” when the machine is wrong. Then the machine can keep on searching among possible ways for solving a problem—until the machine can do as well as the person, and perhaps much better.

But, what is thinking？ People can agree about much that is thinking, and much that is not thinking； but they can’t reach agreement because the word “think” is not a scientific word with an exact meaning. A lot of the discussion is wasted breath because the persons are using different meanings of the word “think”.

People, however, have only had experience with machines that appear to think since 1944.

It would be too early to say that after the next 200 years, machines will not be thinking. And to consider that machines can think gives people a big push to give to machines more and more work in thinking.

1.The underlined part in paragraph three is about computers used in ________.

A．Education. B．Government.

C．Sports. D．Industry.

2.What does “this work” mean in paragraph four？

A．Thinking. B．Teaching.

C．Searching. D．Telling.

3.What is the main idea of paragraph five？

A．There is much to say about thinking.

B．People discuss a lot about thinking.

C．There is no answer to what thinking is.

D．People already know what thinking is.

4.What does the writer want to say in the passage？

A．A machine will do any work in thinking like a human being.

B．A machine can do better translation than human beings.

C．A machine won’t be able to beat every chess player.

D．A machine will be able to make plan programs.

5.Which probably is the best title for the passage?

A．What Is Thinking?

B．Can Machines Think?

C．Can Machines Be Taught to Think?

D．Can Machines Beat All Checkers Players?

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?

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
