第三篇 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. What is the author’s attitude toward the future of film _____
A. Positive.
B. Negative.
C. Uncertain.
D. Worried.

The research published in the British Journal of Cancer backs up a 1988 theory that some as yet unidentified infection caused leukaemia—not the environmental factors widely blamed for the disease. “Childhood leukaemia appears to be an unusual result of a common infection,” said Sir Richard Doll, an internationally—known cancer expert who first linked tobacco with lung cancer in 1950. “A virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection.” Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in children around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the amount of population mixing going on in the area, as large numbers of construction workers and nuclear staff moved into a rural setting. “Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are incomers or locals, are at a higher risk if they are born in an area of high population mixing,” Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer. Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease. Which statement can be supported by Heather Dickinson and Louise Parker’s new findings ______
A. Radiation has contributed to the disease.
B. Putting a lot of people from rural area in a large towns increases the risk of childhood leukaemia.
C. Population mixing is the most important reason for leukaemia cluster.
D. Childhood leukaemia is caused by an unusual infection.
