     20世纪50年代在婆罗洲的许多雅克人身患疟疾，世界卫生组织采取了一种简单的也是直截了当的解决方法：喷洒DDT。蚊子死了，疟疾也得到了控制。可是没多久，大范围的后遗症出现了。由于DDT同时还杀死了吃屋顶茅草的毛虫的天敌──小黄蜂，导致人们的房屋纷纷倒塌。同时，DDT毒死的虫子后来成为壁虎的粮食，壁虎又被猫吃掉，DDT无形中建立了一种食物链，对猫造成杀伤力，猫数量的减少又导致了老鼠的大量繁殖。在有可能大规模爆发斑疹伤寒和森林鼠疫的危险时，世界卫生组织只得被迫向婆罗洲空降14000只活猫，英国皇家空军执行了一次奇特的任务──“降猫行动”。 

（1）蚊子属于昆虫，昆虫身体由          、            、           三部分构成。

（2）在壁虎和老鼠这两种生物中，            属于恒温动物。

（3）通过对以上资料的分析，你认为人类为什么不能随意灭杀某种动物？                                           。

（4）从资料中可以看出：蚊子作为食物链或食物网中的某一环节出了问题，就会影响到整个生态系统，可见动物在维持          中起重要作用。

（5）美国科普作家蕾切尔·卡逊（Rachel Carson）做了杀虫剂破坏生态的大量调查，出版《               》一书，这本书引起了人们对野生动物的关注，唤起了人们的环保意识。

Many people seem to think that science fiction is typified by the covers of some of the old pulp magazines, the Bug-Eyed Monster, embodying every trait and feature that most people find repulsive, is about to grab, and presumably ravish, a sweet, blonde, curvaceous, scantily clad Earth girl. This is unfortunate because it demeans and degrades a worthwhile and even important literary endeavor. In contrast to this unwarranted stereotype, science fiction rarely emphasizes sex, and when it does, it is more discreet than other contemporary fiction. Instead, the basic interest of science fiction lies in the relation between man and his technology and between man and the universe. Science fiction is a literature of change and a literature of the future, and while it would be foolish to claim that science fiction is a major literary genre at this time, the aspects of human life that it considers make it well worth reading and studying for no other literary form does quite the same things.

What is science fiction To begin, the following definition should be helpful: science fiction is a literary subgenre which postulates a change (for human beings) from conditions as we know them and follows the implications of these changes to a conclusion. Although this definition will necessarily be modified and expanded, it covers much of the basic groundwork and provides a point of departure.

The first point-that science fiction is a literary subgenre-is a very important one, but one which is often overlooked or ignored in most discussions of science fiction. Specifically, science fiction is either a short story or a novel. There are only a few dramas which could be called science fiction, with Karel Capek’s RUR (Rossum’s Universal Robots) being the only one that is well known, the body of poetry that might be labeled science fiction is only slightly larger. To say that science fiction is a subgenre of prose fiction is to say that it has all the basic characteristics and serves the same basic functions in much the same way as prose fiction in general, that is, it shares a great deal with all other novels and short stories.

Everything that can be said about prose fiction, in general, applies to science fiction. Every piece of science fiction, whether short story or novel, must have a narrator, a story, a plot, a setting, characters, language, and theme. And like any prose, the themes of science fiction are concerned with interpreting man’s nature and experience in relation to the world around him. Themes in science fiction are constructed and presented in exactly the same ways that themes are dealt with in any other kind of fiction. They are the result of a particular combination of narrator, story, plot, character, setting, and language. In short, the reasons for reading and enjoying science fiction, and the ways of studying and analyzing it, are basically the same as they would be for any other story or novel.

Science fiction is called a literary subgenre because（）

A. it is not important enough to be a literary genre

B. it cannot be made into a dramatic presentation

C. it shares characteristics with other types of prose fiction

D. to call it a "genre" would subject it to literary jargon
