【题目】Hollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics（控制论）, put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”
A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.
The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.
Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.

【题目】How to Do Man-on-the Street Interviews
The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot. 【1】 But with these tips, your first man-on-the-street interview experience can be easy.
When your boss or professor sends you out to do man-on-the –street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?” 【2】
Hit the streets with confidence. 【3】 Say, “Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic,” This is a quick way to get people to warm up to you.
Move on to the next person if someone tells you she is not interested in talking on camera. Don’t get discouraged.
【4】 Each interview that you get on the street shouldn’t be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won’t be able to use it. A safe number of interviews to conduct is about six to ten. 【5】
If your news station or school requires interviewees to sign release forms to appear on the air, don’t leave work without them.
A. Limit your time.
B. As you approach people, be polite.
C. If you don’t own a camera, you can buy one.
D. For new reporters, this can seem like a challenging task.
E. To get good and useful results, ask them the same question.
F. That number of interviews should give you all the answers you need.
G. With a question like this, you will get more than a ‘Yes” or “No” reply.
