50. How can members receive their special offer?
A. By competing a printed form.
B. By writing an application letter to World Books
C. By filling your coupons into boxes.
D. By sending a personal checks. 1. B
分析：该题考察考生推理判断的能力。原文中有种种迹象表明World Book是一个邮购书的俱乐部。如：第二段提到了…plus a total of $1.95 towards postage and packing…我们知道postage(邮资)和packing(包裹)都是邮寄物品时才用到的词。从第三段的第二句话也可以看出来。
2. D
分析：此题考察的是细节。答案就在上题中提到的第三段第二句话。另外也可以用排除法：A提到了折扣，课文提到的是never less than 25 per cent,并不是选项中的often 80%. B, C都没有在文中提及，注意识别这类干扰项。
3. A
分析：此题考察考生判断推理的能力。大家可以看第五段第三句，这句话中提到：the lasted on cookery, gardening, and other popular hobbies,从这句话可以推断一般的家庭会对这些书籍感兴趣。
4. D
分析：此题有一定的难度。我们采取排除法。A 的错误之处在于并不是每个月，而是千半年的每个月;B这种情况不一定，假设前半年每个月至少买一本书(all we ask is that you choose at least one book a month during your first six months),有可能以后每个月都不买(after, it’s up to you how many, or how few, you choose),也就是说不买也是允许的，如果是这种情况，这一年买的书就不是more than 6了;D属于典型的无中生有的干扰项，文中并未提及。所以D是正确选项。意思是：World Book的会员在第一年一定要买够最低限度的书。
5. B
分析：这又是一个细节题。从最后一段第一句可以找到答案。 For centuries Dutch engineers have been fighting a war against water. Their main enemy is the sea. A large part if 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 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 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, but they have 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 the 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.
A piece of reclaimed land is called polder, 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.
