B. Read the text and translate it into Chinese.
An oil spill is the accidental petroleum release into the environment. On land, oil spills are usually localized and thus their impact can be eliminated relatively easily. In contrast, marine oil spills may result in oil pollution over large areas and present serious environmental hazards. The primary source of accidental oil input into seas is associated with oil transportation by tankers and pipelines (about 70%), whereas the contribution of offshore drilling and production activities is minimal (less than l%). Large and catastrophic spills releasing more than 30,000 tons of oil are relatively rare events and their frequency in recent decades has decreased perceptibly. Yet, such episodes have the potential to cause the most serious ecological risk (primarily for sea birds and mammals) and result in long-term environmental disturbances (mainly in coastal zones) and economic impact on coastal activities (especially on fisheries and mariculture海洋生物养殖).

Public concern over marine oil spills has been clearly augmented since 1967. More recently, the highly publicized 1989 spill of the Exxon Valdez in Prince William Sound, Alaska caused unprecedented damage to the fragile Arctic system. Since then, impressive technical, political and legal experience in managing the problem has been gained in many countries and at the intemational level, mainly through a number of Conventions initiated by the Intemational Maritime Organization (IMO). 【课文参考译文】
英国石油公司原油泄漏事件之后，奥巴马总统的一次公开讲话表达出了无数科学家、环保主义者以及墨西哥湾居民的心声。他在讲话中提到，“我们正在应对的是一场巨大的、史无前例的环境灾难”。每天足足有21万加仑的原油泄漏并污染着墨西哥湾，这使得很多人为这次事件对环境所造成的短期和长期的危害感到担忧。 这次原油泄漏事件对脆弱的生态系统带来的严重破坏会持续很多年，甚至数十年。被石油污染的海滩很难被清理干净。更糟糕的是，泄漏的石油对海滩造成污染的时间正是海鸟筑巢和海龟游到岸上孵蛋的季节。 还有更糟的事情，石油污染还可能影响敏感的湿地和红树林海岸，而这将是几乎不可能被清理干净的，有

些人甚至担心这将是永久性的毁坏。这些湿地是捕鱼业和水产品工业的摇篮，也是多种野生动物的栖息地和繁殖地。由于这些湿地面积远远大于海滩的面积，所以它们面临破坏的风险就大大增加了。
在墨西哥湾捕获的鱼类和贝类中足有98%依靠河口生存，这些河口就是江河与海水汇合的地方。而河口又依赖于湿地保证其水的质量并为水产品供应链提供基础。湿地是很多物种觅食、栖息和繁殖的场所。 墨西哥湾水域也是成百上千种水栖动物的家园。石油对海水造成污染的时间越长，水产品食物链被污染的程度就会越大，这最终会造成大量的鱼类死亡以及水产品被严重污染而无法食用。 【参考答案】 阅读理解

原油泄漏是指由于事故导致石油泄漏到环境中的事件。在陆地上，由于原油泄漏发生在局部地区，因此其造成的影响相对来说容易清理。相比之下，海上原油泄漏会造成大范围的石油污染并带来严重的环境危害。约有70%的海上原油泄漏事故的主要原因与油轮和原油运输管道有关，而海上钻井和采油活动引发的原油泄漏事件则占很小的比例（在1%以下）。泄漏三万吨以上的重大灾难性原油泄漏事故并不多见，而且近几十年来这些

重大事故也在逐步减少。尽管如此，这类事故的发生依然会对生态系统，尤其是海鸟和哺乳动物，造成最严重的危害，并且导致海岸地区长期环境失调，对海岸商业活动（如捕鱼业和海洋生物养殖业）带来经济损失。 公众对于海上原油泄漏事件的关注从1967年开始明显上升。较近的一次原油泄漏事故，即众所周知的1989年埃克森公司“瓦尔德斯”号油轮在阿拉斯加州威廉王子湾搁浅事件。这次事故对脆弱的北冰洋生态系统造成了有史以来最为严重的破坏。从那之后，国际海事组织召开了众多会议，帮助很多国家以及国际社会在处理这一问题上获得了很好的技术、政治和法律上的经验。
