大全-12-10

大全-12-10. The geese that gather at the pond of a large corporation create a hazard for executives who use the corporate helicopter, whose landing site is 40 feet away from the pond. To solve the problem, the corporation plans to import a large number of herding dogs to keep the geese away from the helicopter.

Which of the following, if a realistic possibility, would cast the most serious doubt on the prospects for success of the corporation’s plan?

(A) The dogs will form an uncontrollable pack.

(B) The dogs will require training to learn to herd the geese.

(C) The dogs will frighten away foxes that prey on old and sick geese.

(D) It will be necessary to keep the dogs in quarantine for 30 days after importing them.A

(E) Some of the geese will move to the pond of another corporation in order to avoid being herded by the dogs.

A削弱的是什么?A看似与结论无关,C好象与结论关系更大,这种题比较容易错,不知有什么好方法。

原文用狗来赶走鹅来确保直升飞机的停靠。要削弱的话肯定是狗给直升飞机带来

了新的问题。

A说狗将形成无法控制的群体。说明狗会阻挡直升飞机的降落。

C说狗会吓走捕食鹅的狐狸。无关选项。和影响飞机停靠无关。

原来如此,以前只想到鹅和飞机降落有关系,没去想狗和飞机降落的关系。

谢谢!

The dogs will form an uncontrollable pack.
对这句话的理解一直有疑点, 是说狗形成 uncontrollable pack 还是说这些放牧的狗会赶geese最后导致geese形成uncontrollable pack,造成对helicopter的直接威胁。

估计这要有放牧经验的native English speaker来做个澄清了。

found out that the choice C is also very tricky to confuse people

since the old and sick geese will very likely not to fly and pose no

threat to the helicopter.
dont know if this understanding is right or not
