GWD 24-7

24-7 Which of the following most logically completes the argument below?

    The expansion of large-scale farming in Africa and Asia has destroyed much of the natural vegetation on which elephants have historically depended, forcing them to turn to cultivated land to satisfy their enormous appetites. As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since   

(A) when elephants forage for food, they typically travel in herds.

(B) foraging elephants have been known to cause substantial damage even to plants that they do not eat.

(C) some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.

(D) elephants tend to prefer cultivated crops to wild vegetation as a food source

(E) elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.

答案是D，没有问题，但是想问问B选项错在哪里？

我觉得如果大象对即使不吃的植物都进行破坏的话，糟蹋粮食的事情还是会继续发生的。

我觉得Ｂ中forging elephants 指再寻食的大象，根据题意elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation，专门的食物根据地都为大象开辟了，那是不存在需要四处寻食的大象的

以下是引用三脚猫在2005-3-6 12:06:00的发言：

专门的食物根据地都为大象开辟了，那是不存在需要四处寻食的大象的

不明白:不四处觅食只呆在根据地里那大象怎么吃得到粮食?这样的话D还有意义吗?

大象因为有食物偏好，所以有可能走出根据地去吃庄稼

题目中说

就是说已经准备了足够的自然蔬菜,大象不需要去cultivated crop了

b说

Foraging elephants have been known to cause substantial damage even to plants that they do not eat.

除了斑竹所说的那点,我认为此句话无关,因为这句话说的是大象have been known的习惯,那么足够的自然蔬菜中已经包括被毁的部分.不一定大象要离开这块避难所.

D

就很直接.因为不喜欢自然的,即使为大象准备了充足的,大象还是会离开避难所去cultivated的区域吃crop
