题目内容
四、根据下列资料，回答91～100题。
总体看来，2004年世界各国的石油探明储量基本变化不大。但是由于BP公司修正了前苏联、哈萨克斯坦、伊朗、利比亚和苏丹等国的数据， 特别是哈萨克斯坦从l2亿吨修正到54亿吨， 从而使各国在全球石油储量分布中所占的比例发生了一些变化。尽管如此，这并没有影响到欧佩克在全球石油储量中的地位，其石油储量约占全球的74．9％。若从地区来看，中东石油资源最为集中， 占全球的6L 7％ ， 其中仅沙特阿拉伯就达22．1％，占世界石油储量的l／5以上， 其次是伊朗(11．1％)、伊拉克(9．7％)、科威特(8．3％)和阿联酋(8．2％)。在中南美地区， 石油储量最多的委内瑞拉(占世界的6．5％)在该地区占有4／5的石油资源。在欧洲及前苏联地区，修正后前苏联的石油储量占世界的6．1％，哈萨克斯坦占世界的3．3％。其后是挪威(0．8％)和阿塞拜疆(0．6％)。在非洲，修正后利比亚所占的份额达到了3．3％，其次是尼日利亚(3．0％)阿尔及利亚(1．0％)，苏丹修正后也从0．1％升高到了o．5％。北美三国中，美国、加拿大和墨西哥的石油储量份额分别为2．5％、l．4％和l．2％。在亚太地区，石油储量最多的是中国，占世界的l．4％，其次是印度、印度尼西亚和马来西亚，均在0．4％～0．5％之间。2004年世界石油产量达38．68亿吨，比上年增长了4．5％。欧佩克的产量增长了7．7％达到15．88亿吨，从而继续赢得市场份额。伊拉克(增长了50．8％)和委内瑞拉(增长了13．8％)的供应有所反弹，但仍低于先前的最高水平。沙特阿拉伯的产量达到5．o6亿吨，增长了3．7％，创历史新高。中东其他产油国产量也分别有所提高，伊朗增长了2．3％，达到2．o3亿吨；阿联酋增长了5．2％，达到l．26亿吨；科威特增长了8．7％，达到l．20亿吨。俄罗斯也比上年增长了8．9％，达4．58亿吨。而美国由于墨西哥湾飓风的影响，产量下降了2．5％，但仍达3．30亿吨，排名其后的是伊朗和墨西哥(1．91亿吨)。石油产量居世界第六位的是中国，达1．75亿吨。

Passage Four:Questions 36 to 40 are based on the following passage.Where do pesticides (杀虫剂) fit into the picture of environmental disease？ We have seen that they now pollute soil, water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world:
We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.
Responsible public health officials have pointed out that the biological effects of chemicals are cumulative (累积) over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. “Men are naturally most impressed by diseases which have obvious signs,” says a wise physician, Dr. Rene Dubos, “yet some of their worst enemies slowly approach them unnoticed.”
