试题详情

题目:

Parland's alligator population has been declining in recent years, primarily because of hunting.  Alligators prey heavily on a species of freshwater fish that is highly valued as food by Parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption.  Yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased.
 
Which of the following, if true, most helps to explain the decline in the population of the fish species?

选项:

A、The decline in the alligator population has meant that fishers can work in some parts of lakes and rivers that were formerly too dangerous.
B、Over the last few years, Parland's commercial fishing enterprises have increased the number of fishing boats they use.
C、Many Parlanders who hunt alligators do so because of the high market price of alligator skins, not because of the threat alligators pose to the fish population.
D、During Parland's dry season, holes dug by alligators remain filled with water long enough to provide a safe place for the eggs of this fish species to hatch.
E、In several neighboring countries through which Parland's rivers also flow, alligators are at risk of extinction as a result of extensive hunting.

看了答案以后,想问下老师,答案的意思是说很多鱼蛋在旱季的时候是在鳄鱼挖的洞里活着的,这不是说鱼的数量有潜在增加的可能性吗?感觉不能回答问题?

提问:

这道题我已经明白了,只是希望老师能纠正一下我的思路。问题要求解释鱼的下降,看到D的第一反应是相关,但是仔细读了一下感觉方向不对,选项说鳄鱼可以提供给鱼孵卵的洞,当时想的是,那既然鳄鱼越来越少了,这个洞就更方便鱼去孵卵了,数量应该增加,因为吃它的鳄鱼减少了,危险自然也就减少了。所以就排除了。最近做逻辑总是可以判断出是否相关,但经常把方向弄错,于是就不自觉的发散,选了其他不相关的选项。我想请教老师该如何避免这种状况?
