Problems of Internet
The proportion of works cut for the cinema in Britain dropped from 40 per cent when I joined the BBFC in 1975 to less than 4 per cent when I left. But I don’t think that 20 years from now it will be possible to regulate any medium as closely as I regulated film.
The Internet is, of course, the greatest problem for this century. The world will have to find a means, through some sort of international treaty of United Nations initiative, to control the material that’s now going totally unregulated into people’s homes. That said, it will only take one little country like Paraguay to refuse to sign a treaty for transmission to be unstoppable. Parental control is never going to be sufficient.
I’m still very worried about the impact of violent video games, even though researchers say their impact is moderated by the fact that players don’t so much experience the game as enjoy the technical manoeuvres (策略)that enable you to win. But in respect of violence in mainstream films, I’m more optimistic. Quite suddenly, tastes have changed, and it’s no longer Stallone or Schwarzenegger who are the top stars, but Leonardo DiCaprio—that has taken everybody by surprise.
Go through the most successful films in Europe and America now and you will find virtually none that we are violent. Quentin Tarantino didn’t usher in a new, violent generation, and films are becoming much more prosocial than one would have expected.
Cinemagoing will undoubtedly survive. The new multiplexes are a glorious experience, offering perfect Sound and picture and very comfortable seats, thins which had died out in the 1980s. I can’t believe we’ve achieved that only to throw it away in favor of huddling around a 14-inch computer monitor to watch digitally delivered movies at home.
It will become increasingly cheap to make films, with cameras becoming smaller and lighter but remaining very precise. That means greater chances for new talent to emerge, as it will be much easier for people to learn how to be better film-makers. People’s working lives will be shorter in the future, and once retired they will spend a lot of time learning to do things that amuse them—like making videos. Fifty years on we could well be media-saturated as producers as well as audience; instead of writing letters, one will send little home movies entitled My Week. =

Fermi Problem
On a Monday morning in July, the world’s first atom bomb exploded in the New Mexico desert. Forty seconds later, the shock waves reached the base camp where the Italian-American physicist Enrico Fermi and his team stood. After a mental calculation, Fermi announced to his team that the bomb’s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi’s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi’s death in 1954, no physicist has been at once a master experimentalist and a leading theoretician.
Like all virtuosos, Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits—talent we all can use in our daily lives.
To develop this talent in his students. Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven’t the remotest notion of the answer, and you feel certain that too little information had been given to solve it. Yet when the problem is broken into sub-problems, each answerable without the help of experts or books, you can come close to the exact solution.
Suppose you want to determine Earth’s circumference without looking it up. Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours. Three hours is one eighth of a day, and a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3,000 or 24,000 miles. This answer differs from the true value, 24,902.45 miles, by less than four percent.
Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions: It doesn’t matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles. Looking up the answer, or letting someone else find it, deprives you of the pleasure and pride that accompany creativity, and deprives you of an experience that builds up self-confidence. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.
Fermi’s team was impressed by Fermi’s announcement in the base camp because he could even work out the power of the atom bomb in his mind.
听力原文：Woman: Welcome to 'Mid Afternoon,' Dr Carter. Now, I imagine you're here in Birmingham to promote your recently published book 'The Art of Giving Presentations', Is that right？
Man: Well, not really, no! In fact the book isn't really recent at all - it came out at the beginning of last year, I'm actually here this week to give a series of talks outlining some ideas I've had since then.
Woman: So are these ideas the basis for your next book？
Man: Well, it's really too early to talk about that!
Woman: I see, Now tell me, how did you become involved in this particular area of communication skills？
Man: Well, many years ago, as a young sales executive, I had to give presentations, but I felt I wasn't doing them very well. My boss never actually criticised me, and my colleagues weren't doing any better than me, but the point was that I didn't feel satisfied with my performance. You see, if I'm doing something, I have to do it well.
Woman: So you decided to do something about improving your performance.
Man: That's right. I tried to find some books to help me but there weren't really any available in those days... so I eventually decided on a totally practical approach: I tried to find out what my problem was by studying the way the best speakers gave presentations, by talking to them, even watching them prepare. Then I compared their performance with mine.
Woman: And what was your main problem？ Nervousness？ I know that's mine.
Man: Well I had always thought it was nervousness, and it's true that at the time I had no techniques for dealing with that. But I think audiences accept the fact that speakers get nervous, and it really doesn't matter. No, I discovered that my No. I problem was preparation. Nobody had ever told me anything about how to prepare, and I didn't really know how to do it properly.
Woman: And when you realised that, what did you change？
Man: Well, before, I used to go through the whole presentation in an empty room on my own. The first change in my approach came when I realised it's much more realistic and much more useful to do it in front of two or three colleagues. That way you get some feedback. Otherwise you have no idea whether or not your presentation is effective, or which parts might need further attention.
Woman: Is that the method you recommend now？
Man: Well, not quite. What I would advise is to make a video of your practice presentation...
Woman: Instead of using colleagues？
Man: No, a recording of your presentation to them. Then it's easier for all of you to go back and see what's wrong and how it can be improved, It's actually much better than recording other people doing real presentations, however good they are.
Woman: So that's the preparation, but are there any factors which make the presentation itself difficult, even if you are prepared？
Man: Well obviously, yes. Some speakers imagine, quite wrongly, that every audience is unfriendly, at least at the beginning. And this affects their performance. And then there may be a few people who worry about their lack of experience of public speaking. But really what bothers most speakers is things like the OHP and the microphone - are they going to work, and so on,
Woman: Are there any techniques that are effective for overcoming feelings of anxiety？
Man: Well, first I have to say that some people never manage to reduce their anxiety levels. What they can do is learn to relax their face muscles while they speak, so that they look relaxed, even though they feel just as anxious as before. In order to really reduce anxiety, some experts recommend concentrating on something that you enjoyed recently - but I find this is hopeless... I just forget what I was about to say! For me though, what has worked is some simple breathing exercises, breathing in deeply and slowly while making a pause. This definitely slows down the heart rate. That's what I would try first of all.
Woman: Something we can all
