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 land". Very tall and strong walls, called dykes, have 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 problems. These rives are the Rhine, the Maas and the Scheldt. They follow through the Holland into the North Sea. They have cut many passages across the country. At low tides, 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 the water never end, hut they made Holland a bigger and bigger country. In order to prevent floods, the engineers take or reclaim land that was under water. The Dutch have been reclaiming land for seven hundred years.
Land is usually reclaimed from a passage between 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 the land has been drained(that is, when the water has been pumped away). The dykes contain gates, and through these water is pumped out. In many parts of Holland, pumps must be working all the time. If they stopped, there will be very bad floods. [br] Holland is threatened not only by the sea, but also by______.
选项
A、the floods from broken dykes
B、the three rivers
C、the sea tides
D、many passages the three rivers have cut across the country
答案
B
解析
本题为细节推理题,提问的是荷兰不仅受到海洋的威胁,还受到什么威胁。文章第一段主要谈到海洋对荷兰的威胁,而第二段第一句话“Three large rivers are also part of the problems.”的意思为“三条大河也是荷兰面临的问题的一部分”。显然,荷兰也受到三条大河的威胁,因此答案为B)。
