第6题

In science the meaning of the word "explain" suffers with civilization's every step in sea

rch of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first looked into the nature of the electrification of amber, a hard yellowish-brown gum. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul's Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell." Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believe that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that's where they belong, and smoke goes up because that's where it belongs. The goal of Aristotelian science was to explain why things happen. Modem science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.

The aim of controlled scientific experiments is ______.

A．to explain why things happen

B．to explain how things happen

C．to describe self-evident principles

D．to support Aristotelian science

听力原文：It's very nice to see so many faces here tonight. I'm Sergeant Morton, the Crime

Prevention Officer for the area. I'm here this evening to talk about "Local Watch", which some of you may have some experience of. For the rest, " Local Watch" is a service formed by cooperation between local residents and the Police, and I'll be explaining how it operates. In times gone by, most people lived in one area all their lives and so the great majority knew their neighbors very well. If something unusual had happened or if strangers had been acting suspiciously, people would have taken action quickly. These days it's different and people often have little or no idea who their neighbors are.

Why is Sergeant Morton meeting local residents？

A．To warn them about criminals

B．To arrest them

C．To explain a crime prevention scheme

D．To talk about local history
