[单项选择]Modern science fiction movies are often known for their breathtaking special
Line effects. These effects can show us a glimpse of the future, and frequently have
tremendous dramatic force. Sometimes, however, special effects can leave the
science behind to focus only on the fiction. One of the worst offenders is a film’s
(5) depiction of explosions in outer space.
On the Earth, explosions occur in some form of matter, usually air or water.
The change in energy level in the matter creates the energy differential known as
a shock wave. The wave is what creates the characteristic "boom" of an explosion.
Since there is very little matter in outer space, the energy transfer never takes
(10) place. Consequently, there is no sound. Further, because air and water are not
perfect conduits for energy, they measurably slow the travel of the explosive
force. This allows the explosion to unfold in relatively slow motion, which<
A. an attack on the misuse of scientific discoveries by modern film directors
B. a critique of technical developments in science fiction movie special effects
C. an example of how science fiction directors distort science to increase dramatic effect
D. an analogy between science fiction movie special effect and science education in schools

[单项选择]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 exact status of any explanation should be clearly labeled to avoid confusion.
The objectives of science are primarily the discovery and the subsequent unde
A. may lead to antiscientific, "impure" results
B. necessarily precedes applied science, leading to the discovery of a cell
C. is not always as pure as we suppose
D. necessarily results from applied science and the discovery of a cell
