The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

That predatory population increase to control other animals has long been known. Many years ago, the Hudson’s Bay Company records revealed that the fox population went up and down about a year after rabbit population had gone up and down.

Sometimes a situation occurs in which the predatory population is reduced to a level below which nature can readily replace. On Valcour Island in Lake Champlain, a costly campaign resulted in the elimination（消除）of predatory animals only to have birds and small animals increase for four years afterward. Then, lacking predator control, nature resorted to disease to cut down these populations.

Jamaica had an example of nature’s persistence in providing animals for existing habits. Sugar planters, about 75 years ago, imported mongooses（狐猴）to control rats. The mongooses killed off the rats, kids, puppies, and wildlife. Eventually, food became scarce and the mongoose’s population declines.

　　Armstrong’s gift was obvious from the start of his career. His earliest recordings—first with a band led by his former teacher, Joe “King” Oliver, and then with his own band-earned Armstrong international fame for technical originality （独创性）. He freed his playing from the ordinary rhythms of early jazz by creating musical phrases that seemed to oppose the pulse of a song, only to combine them in the place later. His deep and rough voice became as special as his cornet（短号）playing, especially in his scat performances. Scat is a singing style in which meaningless syllables（音节）are repeated without preparation. Armstrong’s scat was among the earliest ever recorded.

　　By 1930, Armstrong had turned to more commercial, less experimental jazz. Some musicians criticized（批评）him for this. But others insisted that the real power of Armstrong’s art lay in its grace and sensitivity, fine qualities of the heart which remained in his music.

　　In the following years, Armstrong traveled around the world as the leading “goodwill ambassador（大使）”of American jazz music. The gentleness and great attraction of “Satchmo” filled his music and made him one of the world’s most beloved performers for over forty years.

　　1．Which of the following best tells what this passage is about?

　　A．Armstrong’s personal attraction.

　　B．Armstrong’s best work.

　　C．A praise for Armstrong’s contribution to jazz.

　　D．A comparison of Armstrong’s music with that of earlier musicians.

　　2．Why was “Satchmo” criticized by some of his workmates in the 1930s?

　　A．For making fewer recordings.

　　B．For losing interest in music.

　　C．For giving up his scat performances.

　　D．For turning his attention away from making changes

　　3．Which of the following is not mentioned as one of the reasons for Armstrong’s success?

　　A．His technical originality.

　　B．His personality.

　　C．His early experiences in “King” Oliver’s band.

　　4．According to the author, what made Armstrong the “goodwill ambassador” of American jazz music?

Our quarrel with efficiency is not that it gets things done, but that it is a thief of time when it leaves us no leisure to enjoy ourselves, and that it strains our nerves when we try to get things done perfectly. In building bridges, American engineers calculate so finely and exactly as to make the two ends come together within one-tenth of an inch. But when two Chinese begin to dig a tunnel from both sides of a mountain both come out on the other side. --The Chinese’s firm belief is that it doesn’t matter so long as a tunnel is dug through, and if we have two instead of one, why, we have a double track to boot.

　　The pace of modern industrial life forbids this kind of glorious and magnificent idling. But, worse than that, it imposes upon us a different conception of time as measured by the clock and eventually turns the human being into a clock himself. (This sort of thing is bound to come to China, as is evident, for instance, in the case of a factory of twenty thousand workers. The luxurious prospect of twenty thousand workers coming in at their own sweet pleasure at all hours is, of course, somewhat terrifying.)Nevertheless, such efficiency is what makes life so hard and full of excitement. A man who has to be punctually at a certain place at five o’clock has the whole afternoon from one to five ruined for him already. Every American adult is arranging his time on the pattern of the schoolboy - three o’clock for this, five o’clock for that, six-thirty for change of dress, six-fifty for entering the taxi, and seven o’clock for arriving at the destination. It just makes life not worth living.

The writer objects to efficiency mainly on the grounds that it ____.

　　 A. gives us rights to have too much leisure time

　　 B. urges us to get things done punctually

　　 C. robs us of leisure time

　　 D. imposes on us a perfect concept of time

In the eyes of the author, the introduction of industrial life gives rise to ____.

　　 A. the excitement of life

　　 B. magnificent idling of time

　　 C. more emphasis on efficiency

　　 D. terrifying schoolboy

The passage tells us ____.

　　 A. Chinese workers come to work when it is convenient

　　 B. all Americans are forced to be efficient against their will

　　 C. Chinese engineers are on better terms with the management

　　 D. Americans ought not to work so hard for efficiency

The author believes that relaxing the rule of punctuality in factories would lead to ____.

　　 A. great trouble                       B. increased production

　　 C. a hard and exciting life                D. successful completion of a tunnel
