1、第一类题材 Study Issue 183As we acquire more knowledge, things do not become more comprehensible, but more complex and more mysterious.Does knowledge render things more comprehensible, or more complex and mysterious? In my view the acquisition of knowledge brings about all three at the same time. This paradoxical result is aptly explained and illustrated by a number of advances in our scientific knowledge. Consider, for example, the sonar system on which blind bats rely to navigate and especially to

2、seek prey. Researchers have learned that this system is startlingly sophisticated. By emitting audible sounds, then processing the returning echoes, a bat can determine in a nanosecond not only how far away its moving prey is but also the preys speed, direction, size and even specie! This knowledge acquired helps explain, of course, how bats navigate and survive. Yet at the same time this knowledge points out the incredible complexity of the auditory and brain functions of certain animals, even

3、of mere humans, and creates a certain mystery and wonder about how such systems ever evolved organically.Or consider our knowledge of the universe. Advances in telescope and space-exploration technology seem to corroborate the theory of a continually expanding universe that began at the very beginning of time with a big bang. On one level this knowledge, assuming it qualifies as such, helps us comprehend our place in the universe and our ultimate destiny. Yet on the other hand it adds yet anothe

4、r chapter to the mystery about what existed before time and the universe. Or consider the area of atomic physics. The naked human eye perceives very little, of course, of the complexity of matter. To our distant ancestors the physical world appeared simple-seemingly comprehensible by means of sight and touch. Then by way of scientific knowledge we learned that all matter is comprised of atoms, which are further comprised of protons, neutrons, and electrons. Then we discovered an even more basic

5、unit of matter called the quark. And now a new so-called string theory posits the existence of an even more fundamental, and universal, unit of matter. On the one hand, these discoveries have rendered things more comprehensible, by explaining and reconciling empirical observations of how matter behaves. The string theory also reconciles the discrepancy between the quantum and wave theories of physics. On the other hand, each discovery has in turn revealed that matter is more complex than previou

6、sly thought. In fact, the string theory, which is theoretically sound, calls for seven more dimensions-in addition to the three we already know about! Im hard-pressed to imagine anything more complex or mysterious.In sum, the statement overlooks a paradox about knowledge acquired, at least when it comes to understanding the physical world. When through knowledge a thing becomes more comprehensible and explainable we realize at the same time that it is more complex and mysterious than previously

7、thought.第二类题材 SocietyIssue 140 What society has thought to be its greatest social, political, and individual achievements have often resulted in the greatest discontent.I strongly agree that great achievements often lead to great discontent. In fact, I would assert more specifically that great individual achievements can cause discontent for the individual achiever or for the society impacted by the achievement, or both. Nevertheless, it is important to acknowledge that whether a great achieveme

8、nt causes great discontent can depend on ones personal perspective, as well as the perspective of time.With respect to individual achievements, great achievers are by nature ambitious people and therefore tend to be dissatisfied and discontent with their accomplishmentsno matter how great. Great athletes are compelled to try to better their record-breaking performances; great artists and musicians typically claim that their greatest work will be their next one-a sign of personal discontent. And

9、many child prodigies, especially those who achieve some measure of fame early in life, later suffer psychological discontent for having peaked so early. Perhaps the paradigmatic modern example of a great achievers discontent was Einstein, whose theoretical breakthroughs in physics only raised new theoretical conundrums which Einstein himself recognized and spent the last twenty years of his life struggling unsuccessfully to solve.Individual achievements can often result in discontent on a societal level. The great achievement of the individual scientists responsible for the success of the Manhattan Project resulted in worldwide anxiety over the threat of nuclear annihilation-a form of discontent with which the worlds denizens will forever be forced to cope. Even individual achievements that at first glance would appear to have benefited society turn out to be causes of great discontent. Cons
