文章以因果、对比的手法写出有没有广告的后果及广告的真正作用。文章首先指出广告商遭批评的原因：广告商夸大和人们认为广告浪费钱财、商品价格就搞；然后作者以有无广告的后果突出其功能，没有广告，商品价更高，生活单调、乏味。有了广告，商品价低，生活丰富多彩，人们获取各种信息。
答案详解
1. C. 广告对社会的服务很有用。作者从三方面来叙述广告作用：第二段点出如果广告不为产品开辟广大的市场，我们就得付出很多钱，正是因为大量的广告费用，消费者的商品才会那么便宜。广告除销售商品外，其重要的功能在通知/告诉信息，有关家用商品的许多只是来自广告，还有新产品的介绍。
第三段讲了美化环境功能。如果火车站的墙上和报上没有广告，那会怎么样。一幅悦人心目，机智的广告将改变一切。
第四段讲了它为我们省钱：别忘了广告对我们口袋作出积极的贡献。报纸、电台、电视台公司没有这笔收入很难生存。我们的报纸，我们付给很少，或者说，我们能享受那么多的节目完全是因为广告商花的钱。如果要我们付报纸的全价，那我们要花多少钱！
最后一段讲了各种专栏的功能。人们可以在这些栏目找工作、买卖房子、宣布婚丧嫁娶信息。这些都围着一个中心：广告对社会服务的有用性。
A. 广告。太笼统。B. 广告之优点。文章不是讲优点，而是讲服务于社会的功能。D. 广告费用。
2. A. 欣赏/赞赏。从上述注释也可推知是A项。最重要的，作者提出种种功能，是为了反驳第一段内提到的论点：完全是非生产企业每年吸收几百万镑，这说明这些大公司利润有多高。最重要的是消费者付的广告费等。反驳更说明了A项对。
B. 值得信任。 C. 批评。 D. 不满意。
3. A. 因为广告商常常爱吹，。见难句译注1.。
B. 因为批评者认为广告浪费钱。 C. 因为广告促使消费者购买不必要的东西。 D. 因为消费者支付更多。
4. C. 优质产品不需要广告。一切产品都需要广告，新产品、老产品都需要。
A. 广告对我们的口袋作出贡献。 B. 我们可以买到我们所需的。 D. 广告使我们生活丰富多彩。这三条都提到也是真实的。
5. C. 文章一开始就提到对广告的批评，然后作者以对比的手法说明其功能。
A. 叙事。B. 描写。 D. 议论。
Passage four(preface)
Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist。
This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture。
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally。
We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living。
