Man, a land animal. But he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two-thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is big. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (贝类动物) is an ancient skill practised in the past mainly by Oriental people, including people in China.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting（开发） fully the food, minerals, and energy sources of the sea will be largely solved.
【小题1】Valuable amounts of minerals are .A．in the ocean waterB．in the warm ocean waterC．on the sea coastD．on the ocean floor【小题2】We can conclude from this passage that .A．the sea resources have largely been used upB．the sea, in the broad sense, has not yet been developedC．the problems that prevent us from using the food, minerals, and energy sources of the sea have already been solved.D．by the year 2020 , the technology will be good enough to exploit all the sea resources【小题3】The underlined words “Oriental people” in the fourth paragraph probably mean .A．the people in AsiaB．African peopleC．European peopleD．American people【小题4】The best title for this passage is .A．Sea HarvestB．Sea FoodC．Technology for Exploiting the SeaD．Man and the SeaD

(答案→)D 解析：【文章大意】本文是一篇说明文。文章阐述了海洋是一个丰富的资源宝库。它为人类提供很多资源保障，从食物到能源。随着人类技术的发展，海洋资源的开发的前景将会越来越广阔。【小题1】D考查细节理解。根据文章第三段中的Valuable amounts of minerals exist on the ocean floor ready to be mined.可知，大洋底存在大量的有价值的矿物质等待被开发。故选D。【小题2】B考查推理判断。根据文章第三段中的The list of riches of the sea yet to be developed by man’s technology is big.可知，有待于人类技术的发展才能被开发的海洋丰富资源的项目是很大的。故选B。【小题3】A考查猜测词义。根据文章中的The culture of fish and shellfish (贝类动物) is an ancient skill practised in the past mainly by Oriental people, including people in China.可知，其中包括中国人。由此推知意为：亚洲人。故选A。【小题4】A考查文章的标题。根据文章最后一段的总结段The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting（开发） fully the food, minerals, and energy sources of the sea will be largely solved.可知，随着人类技术的发展，海洋收获将有改善。故选A。
