A small cloud moves slowly through the air in a hospital operating room (手术室).In the room a patient with cancer(癌症),lies on a table.The cloud is all around the patient,covering her body and filling her lungs(肺).The cloud is not smoke.It is made of millions of nano﹣robots(纳米机器人).These tiny robots move from cell (细胞) to cell in the patient's body,killing the cancer.

    Fighting cancer with nano﹣robots is only an idea today,but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.

    However,nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny,they will have to work in large teams of many thousands to many millions.For this reason,nano﹣robots will have to be programmed(被编程)to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.

    This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming?Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control,nano﹣robots could make the Earth gone.

    What should be done?Should we continue researching nano﹣robots or should we search for other methods?This is one of the many difficult decisions that we have to make in the future.

Reading is an activity people enjoy a lot in their free time. Some like reading newspapers, and others enjoy novels or comic books. I like reading about the lives of great poeple. This always gives me a lot of ideas on how to make my own life better.
Great people are remembered not because they were handsome or beautiful, but because they did not give up when their lives were difficult. They used every opportunity to change their lives and make the world better.
One good example is Orville and Wilbur Wright, the two brothers who invented the airplane. The plane has made the world into a small village.

What is your favorite colour? Do you like yellow, orange, red? If you do, you must be an optimist (乐观者), a leader or an active person who enjoys life, people and excitement. Do you prefer grey and blue? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined(有决心的). You wish to succeed and want other people to see you are successful. At least this is what psychologists(心理学家)tell us, and they should know, because they have been seriously studying the meaning of colour preference (爱好), and the effect that colours have on human beings(人类).They tell us that we don’t choose our favorite colour as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel more cheerful and comfortable than a dark green one, and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(压抑的). Light and bright colours make people not only happier but also more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark grey .
Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colourful things. Remember also that you will know your friends and your enemies better when you find out what colours they like and dislike. And don’t forget that anyone can guess a lot about your character when you choose a piece of handkerchief or a lampshade(灯罩).
According to this passage, ________.

A.one can choose his colour preference
B.one is born with his colour preference
C.one’s colour preference is changeable
D.one has to choose his favourite colour as he can see clearly

C.psychologists have been studying the meaning of colour preference
D.one’s color preference has something to do with his character and colours have effects on human beings
