Tiger sharks are common in the waters surrounding
Tenare Island. Usually tiger
sharks feed on smaller sharks, but sometimes they have attacked tourists
swimming and surfing at Tenare's beaches.
This has hurt Tenare's tourism industry, which is second only to its
fishing industry in annual revenues.
In order to help the economy, therefore, the mayor of the island has
proposed an ongoing program to kill any tiger sharks within a mile of the
beaches.
Which of the following, if true, most strongly
calls into question the likelihood that implementation of the mayor's proposal
will have the desired consequence?
(A) Even if not all the tiger sharks that come
close to the beaches are killed, the existence of the program would reassure
tourists.
(B) Business owners who depend on tourism are
willing to pay most of the cost of implementing the program.
(C) Tourists come to Tenare Island for its beaches,
even though the island features a number of other tourist attractions.
(D) The small sharks on which tiger sharks prey
feed on fish that are commercially important to the island's fisheries.
(E) Not all tourists who come to Tenare Island
enjoy swimming or surfing.
选d
我有个疑问，选项d说small sharks是吃那些对于岛上的渔业发展很重要的一种鱼的。题目里给出的提示是tiger sharks是吃small sharks的。那按照这个关系其实是不是就是tiger sharks 吃small sharks 然后small sharks吃一种fish，这个和问题有什么联系呢？问题是下面哪个会对政府提出的建议起到削弱的作用嘛。政府的建议就是杀掉海滩上一英里以内的tiger sharks因为他攻击了游客会造成她们旅游业的下降，而在那个地区旅游业是仅次于渔业的，说明了渔业的重要性，那答案说small。。。。其实打到这里我已经明白了！！！！本来想不发这个帖子的，现在都打了这么多了就给大家参考下好了！一下子茅塞顿开的感觉真好！大家加油！我9月18号就去考了。加油！
呵呵
这题我也把D的意思看错了，CR的选项总是有很多从句，经常把选项意思理解错导致做错的。
