问题     For centuries Dutch engineers have been fighting a war against water. Their main enemy is the sea. A large part of the country is below sea level. In fact, Holland is also called the "Netherlands," which means "low lands. " Very tall and strong walls, called dykes, have been built to keep out the sea. But in very rough weather the sea may suddenly burst through a dyke, great damage can be caused by floods when this happens.
    Three large rivers are also part of the problem. These rivers are the Rhine, the Maas and the Scheldt. They flow through Holland into the North Sea. They have cut many passages across the country. At low tide, the rivers flow into the sea as usual. But at high tide the sea can flow into the rivers. This is because the land is so low.
    The battles against water never end, but they have made Holland a bigger and better country. In order to prevent floods, the engineers take, or reclaim (开垦，改造) land that was under water. The Dutch have been reclaiming land for seven hundred years.
    Land is usually reclaimed from a passage between two islands. Two dykes are built across the passage, so they block the water between them. Then the engineers dig long canals and pump the water into them. At low tide, the canals empty the water into the sea.
    Because the land is so low, water from the sea and rivers can rise up through the ground. For this reason, the pumps continue working even when the land has been drained (that is, when the water has been pumped away). The dykes contain gates, and through these the water is pumped out. In many parts of Holland, pumps must be working all the time. If they stopped, there would be very bad floods.
    A piece of reclaimed land is called a polder (新辟的低地), and Holland has thousands of polders. Some are very large, but others are quite small. There are farms on many of the polders. Corn and other crops grow well on the drained land, and it gives good grass for cattle. Many small towns and villages stand on polders. Even Amsterdam’s great airport, Schiphol, was built on reclaimed land. This land used to be under the old Lake Haarlem.
Which of the following can be chosen as the best title of this passage?
选项 A、The Dykes in the Netherlands.
B、The Three Large Rivers in Holland.
C、The Fighting Against Water in Holland.
D、The Reclaiming of Land in the Netherlands.
答案C
解析 本题问下面哪个选项可用作本文的最佳标题。通读全文，文章第一段指出：几个世纪以来荷兰的工程师一直在与水作斗争。他们的主要敌人是海洋。这个国家的大部分土地都低于海平面。实际上荷兰也叫尼德兰，它的意思是“低地”。人们建起又高又坚固的墙，称做海堤来阻挡海水。但是，在天气恶劣时，海水可能会冲垮海堤，这样洪水就会带来巨大的损失。接着在文章的后面部分，作者讲到三条大河也是问题的一部分。它们经荷兰流入北海，它们在荷兰的土地上冲出许多河道。在退潮时，河水像往常一样流人大海，但涨潮时海水会流入到河流中，这是因为陆地太低。因此同水的斗争永无休止。为了阻止洪水，工程师们从水底开发或开垦土地。所以全文是围绕着荷兰人与水的斗争来写的。因此，本题的正确答案应是C。
