Our world of the mid-1990s faces potentially bursting change. The question is in what direction will it take us 46) Will the change come from worldwide initiatives that reverse the degradation of the planet and restore hope for the future, or will it come from continuing environmental deterioration that leads to economic decline and social instability There is no precedent for the rapid substantial change we need to make. 47) Building an environmentally sustainable future depends on restructuring the global economy, major shifts in human reproductive behavior, and dramatic changes in values and lifestyles. Doing all this quickly adds up to a revolution that is driven and defined by the need to restore the earth’’s environmental systems. If this Environmental Revolution succeeds, it will rank with the Agricultural and Industrial Revolutions as one of the great economic and social transformations in human history. Like the Agricultural Revolution, it will dramatically alter population trends. 48) While the former set the stage for enormous increases in human numbers, this revolution will succeed only if it stabilizes human population size, reestablishing a balance between people and natural system on which they depend. In contrast to the Industrial Revolution, which was based on a shift to fossil fuels, this new transformation will be based on a shift away from fossil fuels. 49) The two earlier revolutions were driven by technological advances―the first by the discovery of farming and the second by the invention of the steam engine, which converted the energy in coal into mechanical power. The Environmental Revolution, while it will obviously need new technologies, will be driven primarily by the restructuring of the global economy so that it does not destroy its natural support system. The pace of the Environmental Revolution needs to be far faster than that of its predecessors. The Agricultural Revolution began some 10,000 years ago, and the Industrial Revolution has been under way for about two centuries. But if the Environmental Revolution is to succeed, it must be compressed into a few decades. Progress in the Agricultural Revolution was measured almost exclusively in the growth in food output that ually enabled farmers to produce a surplus that could feed city dwellers. Similarly, industrial progress was gained by success in expanding the output of raw materials and manufactured goods. 50) The Environmental Revolution will be judged by whether it can shift the world economy into an environmentally sustainable development path, one that leads to greater economic security, healthier lifestyles, and a worldwide improvement in the human condition.

【单选题】21（） A. of which B. in which C. with which D. by which
A.
Silence is unnatural to man. He begins life with a cry and ends it in stillness. In the interval he does all he can to make a noise in the world, and there are few things 21 he stands in more fear than of the 22 of noise. Even his conversation is 23 a desperate attempt to prevent a dreadful silence. If he is introduced to a fellow mortal and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of 24 of the emptiest-headed chatterbox. He knows that ninety-nine percent of human conversation means 25 the buzzing of a fly, but he longs to join in the buzz and to prove that he is man and not a wax-work figure. The object of conversation is not, 26 the most part, to communicate ideas; it is to keep up the buzzing sound. Most buzzing, 27 is agreeable to the ear, and some of it is agreeable even to the 28 . He would be a foolish man, however, who waited until he had a wise thought to take part in the buzzing with his neighbors. Those who despise the weather as a conversational opening seem to be ignorant of the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are 29 if they are merely allowed to go on making a noise into other people’s ears though they have nothing to tell them except that they have seen a new play. At the end of an evening during which they have said nothing at immense length, they justly 30 themselves on their success as conversationalists.
