[单项选择]Passage One
In science the meaning of the word “explain” suffers with civilization’s every step in search 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 speculated on the electrification of amber. 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, believed that man could arrive at an understanding of reality by reasoning from self-evid
A. disapproved of by most modern scientists
B. in agreement with Aristotle’s theory of self-evident principles
C. in agreement with scientific investigation directed toward “how” things happen
D. in agreement with scientific investigation directed toward “why” things happen

Passage Three
The word science is heard so often in
modern times that almost everybody has some notion of its meaning. On the other
hand, its definition is difficult for many people. The meaning of the term is
confused, but everyone should understand its meaning and objectives. Just to
make the explanation as simple as possible, suppose science is defined as
classified knowledge (facts). Even in the true sciences
distinguishing fact from fiction is not always easy. For this reason great care
should be taken to distinguish between beliefs and truths. There is no danger as
long as a clear difference is made between temporary and proved explanations.
For example, hypotheses and theories are attempts to explain natural phenomena.
From these positions the scientist continues to experiment and observe until
they are proved or discredited. The exa A. the study of unrelated subjects B. an attempt to explain natural phenomena C. the study of unrelated fields D. classified knowledge

[单项选择] Passage Four
In science the meaning of the word
"explain" suffers with civilization’s every step in search of reality. Science
can not really explain electricity, magnetism, and gravitation; their effects
can be measured and predicted, but of their nature no more is known to the modem
scientist than to Thales who first speculated on the electrification of amber.
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, 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 A. to explain why things happen B. to explain how things happen C. to describe self-evident principles D. to support Aristotelian science
[单项选择] Passage One
Although no one is certain why
migration occurs, there are several theories. One theory claims that prehistoric
birds of the Northern Hemisphere were forced south during the Ice Age. As the
glaciers melted, the birds came back to their homelands, spent the summer, and
then went south again as the ice advanced in winter. In time, the migration
became a habit in spite of the disappearance of glaciers.
Another theory proposes that the ancestral home of all modern birds was
the tropics. When the region became overpopulated, many species were crowded
north. During the summer, there was plenty of food, but during the winter,
scarcity forced them to return to the tropics. A more recent
theory suggests a relationship between increasing daylight and the stimulation
of certain glands(腺)in the birds’ bodies that may prepare them fo A. birds should migrate in the middle of the winter B. longer days cause changes in the bodies of birds C. seasonal changes in the length of days do not affect migration D. increasing daylight increases the distance of migration
