大学英语综合教程 第一册 unit 3a

[05:03.60]and this can be conveyed by words and diagrams,without the use of equations
[05:10.73]The science people learn in school can provide the basic frame-work.
[05:16.34]But the rate of scientific progress
[05:20.18]is now so rapid that there are always new developments that have occurred
[05:26.11]since one was at school or university.
[05:29.87]I never learned about molecular biology or transisitors at school,
[05:35.12]but genetic engineering and computers
[05:38.63]are two of the developments most likely to change the way we live in the future.
[05:45.29]Popular books and magazine articles about science
[05:49.91]can help to put across new development,
[05:53.57]but even the most successful popular book
[05:56.99]is read by only a small proportion of the population.
[06:01.74]Only television can reach a truly mass audience.
[06:06.05]There are some very good science programmes on TV,
[06:10.42]but others present scientific wonders simply as magic,
[06:14.96]without explaining them
[06:17.18]or showing how they fit into the framework of scientific ideas.
[06:22.54]Producers of television science programmes
[06:26.01]should realize that they have a responsibility to educate the public,
[06:31.76]no just ectertain it.
[06:34.37]The world today is filled with dangers,
[06:38.00]hence the sick joke that the reason we have not been contacted
[06:42.99]by an alien civilization
[06:46.20]is that civilizations tend to destroy themselves when they reach our stage.
[06:51.95]But I have sufficient faith in the good sense of the public
[06:56.31]to believe that we might prove this wrong.
