W: So what happened? I guess (80)s           found you, right?  _______

of the cold. I spent two months in the (81)h          .                 _______

disabled. We can use modern (83)t_________  to help.                 _______

W: And you built these great new legs. Can you go

mountain (84)c          again?                                                _______

M: Yes, I can. In fact, these are better than climb shoes. The spring(弹力)

design means they are much more (85)p         .                         _______

Technology: Taking the good without the bad?

Very soon, unimaginably powerful technologies will remake our lives.This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them.There’s a growing gap between our technological capability and our basic scientific understanding.We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous.

The technologies that are particularly dangerous over the next hundred years are nanotechnology (纳米技术), artificial intelligence and biotechnology.The benefits that they will bring are beyond doubt.But they are going to be very, very dangerous.I’m working in the field of artificial intelligence.I have a model design for something that might be 50,000 million times smarter than the human brain.Target date is 2010.The only thing that's not possible in the film Terminator(终结者) is that the people win.If you're fighting against technology w hich is 50,000 million times smarter than you, you probably will not win.

Nanotechnology.We've all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue.And certainly in biotechnology, we've really got a big problem because it's converging with nanotechnology and IT.Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek(星际迷航).And those superhuman organisms might not like us very much.

Eventually these technologies will become routine.That’s a threat to humanity.I don’t think it’s possible to slow it down.So what we need to do is accelerate the scientific research and try to get some extra tools.The problems facing us in the future are getting bigger and bigger.I think if we don’t get some proper science done, the future is hopeless indeed.

1.From the text, we know that the author’s greatest concern is         

A.our lack of technological understanding of the process involved

B.our lack of technological capability

C.creating technology without really understanding the basic science

D.Our refusal to face the consequences of the technology we create

2.It can be inferred from the text that the author         

A.thinks people overvalue the capabilities of technology

B.is not optimistic that artificial intelligence will always be used positively

C.thinks that we should take science fiction movies more seriously

D.believes artificial intelligence is the greatest threat we face technologically

3.Why does the author say it is not possible in the film Terminator that the humans win?

A.Because the power of the technology is exaggerated(夸大).

B.Because the strength of the machines is much greater.

C.Because machines with that much intelligence can easily defeat humans.

D.Because human beings are not courageous enough to win the battle.

 

One would have to be a fool to overlook the importance of using positive thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little w*w^w..c~o*mchemicals and good feelings which will reinforce the positive thoughts.

For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.

It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.
