听力原文： In an earlier age, there was a great distinction in the public mind between science and engineering. Whereas the scientist was thought of as an intellectual, motivated by a desire for knowledge and order, the engineer was thought of as a busy, practical person, involved in producing something for which the public was willing to pay. The scientist might discover the laws of nature, but the engineer would be the one to exploit them for use and profit.
Historically, however, this distinction has not always been valid. In every century, noted theoretical scholars were deeply involved in the practical application of their own work. For example, in the seventeenth century, Christian Huygens, a Dutch astronomer, mathematician, and physicist who developed theorems on centrifugal force and motion also developed the first accurate timepiece. In the eighteenth century, the British mathematician and philosopher Sir Isaac Newton was credited not only with advancing theories of mechanics and optics, but also with inventing the reflecting telescope, a direct application of his theory. In the nineteenth century, the French chemist and bacteriologist Louis Pasteur first proposed theories of disease, and then set about the discovery of vaccines for anthrax and rabies, as well as the process for purification that bears his name to this day.
I propose that the popular detachment of science from engineering has not provided us with useful model for comparison, and perhaps not even a historically correct one.
Questions:
6. According to public opinion in the past, how did a scientist differ from an engineer？
7.Who was Christian Huygens？
8.Why did the lecturer discuss the work of Huygens, Newton, and Pasteur？
9.What was the lecturer's opinion about science'？
10.Who set about the discovery of vaccines for rabies？

A．The scientist exploited the laws of nature.
B．The engineer was more practical.
C．The engineer was an intellectual.
D．The scientist was deeply involved in the practical application of his or her work.
M: Well, it looks just like an ordinary plane, really. It’s about the same size as a plane, and it can carry about 50 passengers.
W: But it doesn’t act like an ordinary plane, does it？
M: No, it’s much faster. For example, you could fly from London to Beijing in only 30 minutes.
W: My goodness! And how does it work？
M: Well, shortly after taking off, the plane leaves the earth’s atmosphere and goes into orbit around the earth until it returns to the ground.
W: So it’s really a kind of space rocket.
M: Not really, no, for two reasons. First, a space rocket can only be used once, but this space plane can be used for many times. Second, while the plane is traveling through the atmosphere, the pilot can fly it just like an ordinary plane.
W: It sounds very exciting.
(20)
A．A satellite.
B．An ordinary plane.
C．A space plane.
D．A space rocket.
The study of philosophies should make our own ideas flexible.
We are all of us apt to make 【M1】______
certain general ideas for granted, and call them common sense. We should learn that other people have held quite different ideas, but that our own have started as
very original guesses of philosophers. 【M2】______
A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the
questions in which philosophers still argue. 【M3】______
For example, Plato thought that when we saw something, one ray of light came to it from the sun,
and the other from our eyes and that seeing was something like feeling with a stick. 【M4】______
We now know that the light comes from the sun, and is reflected into our eyes. We don't know in much detail how the changes in our eyes give to sensation. But there is every, 【M5】______
reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty full cleared up. 【M6】______
But if our descendants know the answers to these questions and others that perplex us today, there would still be one field of which they do not know, namely the future. 【M7】______
While exact our science, we cannot know it as we know the past. 【M8】______
Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment.
That is one reason 【M9】______
that Marx and Engels quite rightly wrote to many philosophical
problems that interested in 【M10】______
their contemporaries.
【M1】
