Anyone who trains animals recognizes that human and animal perceptual capacities are different. For most humans , seeing is believing, although we do occasionally brood about whether we can believe our eyes. The other senses are largely ancillary; Most of us do not know how we might go about either doubting or believe our noses. But for dogs, scenting is believing. A dog’s nose is ours as the wrinkled surface of our complex brain is to the surface of an egg. A dog who did comparatively psychology might easily worry about the consciousness of a squid. Hi7y(h?wj
. [3 l/ }# f8 \ w- oWe who take sight for granted can draw pictures of scent, but we have no language for doing it the other way about, no way to represent something visually of humans can by means of actual scent. Most humans cannot know, with their limited noses, what they can imagine about being deaf, blind, mute, or paralyzed. The sighted can, for example, speak of a blind person as “in the darkness,” but there is no corollary expression for what it is that. We are in relationship to scent. If we tried to coin words, we might come up with something like “scent-blind.” But what would it mean? It could, have the sort of meaning that “color-blind” and “tone-deaf” do, because most of us have experienced what “tone” and ”color” mean in those expressions, but we don’t know what “scent” means in the expression “scent-blind”. Scent for us can be only a theoretical, technical expression that we use because our grammar requires that we have a noun to go in the sentences we are prompted to utter about animals’ tracking. We don’t have a sense of scent. What we do have is a sense of smell—for Thanksgiving dinner and skunks and a number of things we call chemicals.- m( Q1 x6 P" M4 B/ a1 _+ F' F) L, k .Evy_o\^

, o- j* _( G% g W( }3 J7 oFaced with rapid change and the fear and uncertainty that go with it, individuals as well as nations sometimes seek to return to the ways of the past as a solution. In the early 1980s the idea of returning to the ways of the past had a strong appeal to many Americans who increasingly viewed their past as being better than their future. Yankelovich and Lefkowitz have observed that until the 1970s Americans generally believed that the present was a better time for their country than the past and that the future would be better than the present; by 1978, however, public opinion polls showed that many Americans had come to believe that trust the opposite was true; he past had been better for the country than the present, and the present was better than the future would be better than the future would be.7 b3 W8 x9 a0 z2 w .~A*=
The population appeal of returning to the ways of the past as a solution to the problems of the 1980s was demonstrated when Ronald Reagan was elected President of the United States in 1980. Time magazine chose President Reagan as its “man of the year” and said of him:” tellectually, emotionally, Reagan lives in the past.”; x. o) N9 L: I8 Q0 \. a1 t QfM zF
One of President Reagan’s basic beliefs is that the United States should return as much as possible to its pre-1980 ways. In those times business institutions were strong and government institutions were weak. Reagan believes that the American values of individual freedom and competition are strengthened by business and weakened by government. Therefore, his programs as President have been designed to greatly strengthen business and reduce the size and power of the national government. By moving in this way toward the practices of the past, president Reagan believed that the standard of living of Americans would begin to improve once more in the 1980s as it had done throughout most of the nation’s history." |7 X: H0 o# _4 I( } F_

Passage 4 >AoK/(yL.
. L& y7 u5 U* q& ?4 A: i2 S9 _The average population density of the world is 47 persons per square mile. Continental densities range from no permanent inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. In Europe the range is form 4 per square mile in Iceland to 831 per square mile in the Netherlands. Within countries there are wide variations of population densities. For example, in Egypt, the average is 55 persons per square mile, but 1300 persons inhabit each square mile in settled portions where the land is arable. tz#gClo
8 d4 w; I( X; D/ A* ~High population densities generally occur in regions of developed industrialization, such as the Netherlands, Belgium, and Great Britain, or where lands are intensively used for agriculture, as in Puerto Rico and Java. O^/Maa/D1
% q5 f: _! n3 d/ O$ s( U( R Low average population densities are characteristic of most underdeveloped countries. Low density of population is generally associated with a relatively low percentage of cultivated land. This generally results from poor quality lands. It may also be due to natural obstacles to cultivation, such as deserts, mountains or malaria, infested jungles; to land uses other than cultivation, as pasture and forested land; to primitive methods that limit cultivation; to social obstacles; and to land ownership systems which keep land out of production./ R, `1 A8 l, Y7 d3 s, z9 X9 t 6x"Q
More economically advanced countries of low population density have, as a rule, large proportions of their populations living in urban areas. Their rural population densities are usually very low. Poorer developed countries of correspondingly low general population density, on the other land, often have a concentration of rural population living on arable land, which is as great as the rural concentration found in the most densely populated industrial countries. +k

Passage 5( N" t( A' b, U" ]5 u `DT3x{}_S
A new era is upon us call it what you will; the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we are partly there, The percentage of people who earn their living by making things has fallen dramatically in the Western world. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth of the economic transformation can’t be measured by numbers alone, because it also is giving rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers----all these are being challenged. `/HUV&i"S
+ D% m& P z7 ~: }: S9 `" {# f. F0 S; S We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possible could have foreseen the ways in which a single invention, the chip, would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: Information and Knowledge will become even more vital, and the people who possess it, whether they work in manufacturing or services, have the advantage and produce the wealth. Computer knowledge will become as basic a requirement, as the ability ‘to read and write’. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant. It will be the way you do your job. }(egMx;"3J

A package has two important functions. First, it must have utility for the consumer and for the intermediaries in the channels of distribution. The package should protect the product, prevent breakage or spoilage, and extend the product’s life. It should be convenient for the consumer to use and convenient for intermediaries to ship, sore, and stack on a shelf. Resellers prefer packages that help cut shipping costs and reduce shoplifting. The package should also be easily disposable but not contribute to excessive waste.4 {2 M5 W- R) _! h0 s: c0 g1 i <w\:<5e '
Second, the package should facilitate promotional communication by allowing clear brand identification and promoting a product’s features. A good label on the package, together with proper instruction on a product’s use, for example, can reduce the amount of personal selling needed to convince the consumer to buy the product. Packaging such as an attractive Christmas box or a distinctive shape can lead a substantial increase in a product’s sales. These features, of course, must be weighed against the negative impact that charges of improper packaging can carry.
