If we view a science as a body of systematized knowledge, then chemistry is usually called a natural science because it (26) knowledge of the natural world. At times we may wonder (27) there is no complete system (28) all of chemistry fits perfectly. Gaps in the present system, however, show that chemistry is still a(n) (29) subject and that we (30) all of its facts, laws, and theories. (31) , chemistry as a science is very much (32) us today, and its future holds the bright promise (33) much more to come. Man’s knowledge about himself and nature has grown into (34) sciences. The growth of the separate sciences has been more developmental than intentional. The separation of the natural sciences into physical and biological sciences, and physical sciences into physics and chemistry, happily (35) a larger body of knowledge into more manageable parts. At the same time we should remember that the concepts, techniques, and applications of the various sciences are interdependent and not exclusively a part of one science or (36) . In this (37) , chemistry is a key science among the natural sciences because everyone, (38) the area of natural science he wishes to pursue, needs at least an introduction to the principles and simpler applications of chemistry as a foundation for his specialty. Chemistry deals with the (39) of matter, changes in matter, the laws and principles (40) these changes, and the concepts and theories that interpret them.
TEXT D The year 1400 opened with more peacefulness than usual in England. Only a few months before, Richard II, weak, wicked, and treacherous, had been deposed (废黜), and Henry IV declared king in his stead. But it was only a seeming peacefulness, lasting for but a little while; for though King Henry proved himself a just and a merciful man—as justice and mercy went with the men of iron of those days—and though he did not care to shed blood needlessly, there were many noble families who had been benefited by King Richard during his reign, and who had lost somewhat of their power and prestige from the coming in of the new king. Among these were a number of great lords who had been degraded from their former rifles and estates, from which degradation King Richard had lifted them. They planned to fail upon King Henry and his followers and to massacre (屠杀) them during a great tournament (中世纪马上比武大会) which was being held at Oxford. And they might have succeeded had not one of their own members betrayed them. But Henry did not appear at the lists; whereupon, knowing that he had been lodging at Windsor with only a few attendants, the conspirators marched there against him. In the meantime, the king had been warned of the plot, so that instead of finding him in the royal castle, they discovered through their scouts that he had hurried to London, and that he was marching against them at the head of a considerable army. So nothing was left but flight. One and another, they were all caught and some killed. Those few who found friends faithful and bold enough to afford them shelter dragged those friends down in their own min. How did King Henry find out about the plot
There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds. People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, hurt many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing (批评) and being disliked is perhaps taken up by imitation (模仿). It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit. Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These people should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact (接触) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels. People who are unhappy ______.
