中国海洋大学 英语期末考试

英语翻译：Unit1A海洋作为我们这个世界必不可少的部分，缓冲气候变化带来的危害，为我们提供食品和很多现代药物。

但是海洋与人类之间的这种联系却一直没有引起人们足够的重视。

直到近来，由海洋保护生物学家D带领的团队，从多学科角度，探索人类大脑与海洋之间的联系，提出一个新的研究方向--神经保护。

这一研究引起了海洋科学方面的一场革命。

著名海洋学家W博士，把深层水流动现象称为“海洋循环带”。

这种说法太过简单的描述了一个复杂的过程。

杜克大学的S博士综合考虑各种证据后，推翻了我们对于海洋颠覆的观点。

无论这场革命结果如何，有一点是毋庸置疑的，海洋紧密的将地球联系在一起。

我们要摒弃传统的看法，从一种新的视角来保护海洋。

The ocean, as an indispensable part of our world, buffers our weather, and provides us with food and many of modern medicines. However, we just ignored (didn’t give enough attention to) the connecti vity between the ocean and human sphere. Only until recently, have the team led by marine conservation biologist Dr. Wallace J. Nichols started to explore the connection between human minds and the ocean from multidisciplinary perspectives. They put forward a new research field—neuroconservation, which led to a revolution in marine science.Dr. Wally Broecker, a famous oceanographer, called the phenomenon of deep water circulation “Ocean Conveyor Belt”. This statement is an oversimplification of a complex process. Dr. Susan Lozier from Duke University overwhelmed the idea about ocean overturning after considering/weighing different pieces of evidence. Whatever the outcome would be, there is no doubt that the ocean holds our planet tightly. We have to abandon the old notion and try to protect the ocean from a new perspective.2AThe ocean is the cradle of life. Therefore, the study of marine ecology is not only conducive to the survival of the conservation of biological environment, and is directly related to the development and utilization of marine living resources. Ocean researchers find that marine microbes play animportant role in maintaining the oxygen and carbon dioxide balance in the Earth's atmosphere; sunscreens made of algae can be used in skin care industry; a natural mechanism for iron fertilization is helpful to solve iron deficiency; mass catching of fish for obtaining oil poses risks for extinction of the overfished species; untreated wastewater or sewage which flow into the sea transmits human pathogen to marine corals. These are path-breaking findings in marine science. Researchers are going on various marine biology issues such as oil spills in marine water, ability of some marine species to change their sex and synthesis of renewable energy source. If it is feasible to obtain biofuel from seaweed in the future, it will be a priceless contribution for solving energy crisis of human beings.Unit2B叶绿素是一类与光合作用有关的最重要的色素。

它实际上存在于所有能营造光合作用的生物体中，1899年，一位意大利科学家发明了一种简单但是比较精确地测量叶绿素水平的方法，从20世纪50年代起，科学家们已经通过收集和分析海水样本测量叶绿素色素的浓度，对叶绿素进行量化。

70年代，我们已经使用卫星测量海水颜色的浓度，做同样的事情，并且扩大了测量的空间覆盖范围。

到了现代，科学家们已经可以通过实验室对同一水柱水质的分析，确定海水深度与叶绿素数量的具体定量关系。

由此可见，我们已经拥有了100多年的叶绿素数据，这是一个不小的壮举。

Chlorophyll is the most important pigment related to photosynthesis. Chlorophyll is actually present in all photosynthetic organisms. In 1899, an Italian scientist developed a simple but accurate method of determining chlorophyll levels. Since 1950s, scientists have quantified chlorophyll by collecting and analyzing water samples to measure concentrations of chlorophyll pigment. Starting in the 1970s, we have also used satellite measurements of the intensity of the ocean's green color to do the same with much greater spatial coverage. Scientists in the modern era have determined the specific quantitative relationship between the depth and the amount of chlorophyll with laboratory analysis of water from the same column. Thus it can be seen that we have more than 100 years of chlorophyll data in the ocean, which is no small feat.Unit3A海洋状况堪忧，证据不胜枚举。

海水变酸，使得很多海洋生物生存困难。

某些物种的稀缺会破坏食物链，从而导致整个生态系统失衡。

作为海洋雨林的珊瑚礁，由于受到过度采集、水温过高、海洋酸化等因素的影响，大部分已受到严重损害。

全球变暖使海洋升温，冰川融化，导致海平面上升，使沿海地区居民处于危险的境地。

人类施加给生态系统太多压力，这些压力可能会永久的改变海洋。

对于人类而言，每一种改变都是巨大的灾难。

坐视不管或把这些当成是小麻烦都不是明智之举。

相反，该是我们采取必要措施扭转这一局面的时候了，在某些情况下，应该废除渔业补贴，可转让捕捞配额。

在为时已晚之前，我们必须制定出有效的策略。

The sea is suffering. The evidence abounds. It becomes acid, making marine life difficult. The dearth of some species will disrupt the food chain, which will in turn destabilize the entire ecosystem. The coral reefs, as the rainforests of the sea, are affected by overfishing, overheating, ocean acidification, etc. Most of them are therefore gravely endangered. Global warming causes oceans to warm up and glaciers to melt, which will raise the sea level and endanger the inhabitants of coastal areas. Humans inflict too many stresses on marine ecosystem, which may permanently change the ocean. For humans, each of these changes is a catastrophe. It is not wise for us to sit back or take it for minor distractions. Conversely, it is high time we did something to put matters right. Fishing subsidies should be abolished and fishing quotas be made transferable in some cases. We must develop effective strategies before it may be too late.Unit4A一些科学家认为有必要采用更为激进的方法，即改造地球的方法，来处理气候问题。
