part b directions: in the following article, some sentences have been removed. for questions 41—45, choose the most suitable one from the list a—g to fit into each of the numbered blank. there are two extra choices,which do not fit in any of the gaps. the history of life on earth has been a history of interaction between living things and their surroundings. to a large extent, the physical form and the habits of the earth's vegetation and its animal life have been molded by the environment. considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. 41）_________________________ during the past quarter century this power has not only become increasingly great but it has changed in character. the most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. this pollution is for the most part irrecoverable. 42）_______________. chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and work unknown harm on those who drink from once pure wells. "man can hardly even recognize the devils of his own creation," as a scientist has said. it took hundreds of millions of years to produce the life that now inhabits the earth. 43）_________________________________________________. 44）_____________________________________________________. radiation is now the unnatural creation of man's tampering with the atom. the chemicals are the synthetic creations of man's inventive mind, having no counterparts in nature. 45）_____________________________________________. and even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the united states alone. among them are many that are used in man's war against nature. since the mid 1940's over 200 basic chemicals have been created for use in killing insects, weeds, and other organisms described as "pests." [a]the rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. [b]future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life. [c]only in the present century has one species man acquired significant power to alter the nature of his world. [d]i do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. [e]in this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. [f]given time not in years but in millennia life adjusts, and a balance has been reached. but in the modern world there is no time. [g]to adjust to these chemicals would require not merely the years of a man's life but the life of generations. part c directions: read the following text carefully and then translate the underlined segments into chinese. your translation should be written clearly on answer sheet 2. （10 points） april the 3rd was the day we attempted to reach mount everest. the morning saw us all up and rushing about the camp at daybreak. we bumped down the nine miles of dusty track, each clutching a camera or one of the more delicate instruments to our chests in an endeavor to make our bodies absorb as many of the shocks from the bumpy track as possible. the ground staff were already busy on our arrival. 46）the sheds where the aircraft were kept had been opened and the great machines were being manhandled out onto the runway. the bottles of oxygen were carefully placed in their clips and connected to the system. 47） the vertical cameras were fitted and tested, air frames and engines were inspected and tested in every detail. pilots and observers cared greatly about their equipment, trying on oxygen masks which they had tried on many times before, readjusted to a nicety. they then rechecked the charts which had been carefully prepared to allow accurately for the increasing wind speeds during the climb—all trying to keep themselves occupied during that tense half-hour wait for the return of the reconnaissance machine. 48）there had been so much preparation for this flight, and there was still so much of the unknown about it, that the crews could not help being slightly affected by the general excitement. waiting is always unpleasant, and we were all relieved to see the reconnaissance machine diving down through the dust haze. the air commodore who commanded it brought welcome news. 49）though he had been unable to climb above the dust, he had been able to see towards the mountains through the top of the haze and there was a cloudless sky. this was splendid: no cloud to spoil the photography. we had promised not to attempt the flight if the wind exceeded 40 miles an hour, but this was the first time we had found the wind under 100 miles an hour. 50）we worked out the implications and reckoned that, provided we did not spend more than fifteen minutes at the summit, we could get back inside our petrol endurance. we might wait for days and weeks and not get another opportunity. the air commodore weighed the position carefully and gave the word "go". section ⅲ writing part a 51.directions: you are a secretary in a corporation. now you are supposed to write a letter to a raw material supplier requiring for detailed information of their products. the letter must involve: 1）express your interest with their product, 2）ask for the detailed information, 3）a wish for possible business cooperation in the future. you should write about 100 words on answer sheet 2. do not sign your name at the end of the letter. use "jane green" instead. you do not need to write the address. （10 points） part b 52.directions: study the following picture carefully and write an essay to 1）describe the picture and interpret its meaning 2）give your comment on the phenomenon. you should write about 200 words neatly. sectionⅰuse of english |
