To Heslaw: 问一题－新东方绿皮

arizonahk

感觉还是没看明白题目

请大牛指教 看看你们怎么理解题目，特别是红色部分没看明白。

Some observers have concluded that the rise in the price of pepper means

that the switch by some growers from pepper to cocca left those growers no

better off than if none of them had switched;this conclusion,however,is unwarranted because it can be inferred

to be likely that

A) those growers could not have foreseen how high the price of pepper would go

B) the initial cost involved in switching from pepper to cocca is substantial

C) supplies of pepper would not be as low as they are if those growers had not switched crops

D) cocca crops are susceptible to being reduced by bad weather as are pepper crops

E) as more growers turn to growing cocca, cocca supplies will increase and the price of cocca will fall precipitously.

答案是b么？

小佳

pepper价格上涨导致那些pepper grower走了之后发现走了还不如不走。

问削弱。

选c吧，就是说如果他们不走价格不会涨。假性因果。

 rise in the price of pepper means

that the switch by some growers from pepper to cocca left those growers no

better off than if none of them had switched

因为pepper 价格增高，所以说，那些人(pepper种植者的一部分)选择从种pepper变成种cocca，还不如不换的好

答案应该是Ｃ

C) supplies of pepper would not be as low as they are if those growers had not switched crops

如果这些人没有换种植作物，pepper的供应量就不会下降那么多。所以价格也就不会增高了

这种题属于因果题

A) those growers could not have foreseen how high the price of pepper would go　无关

B) the initial cost involved in switching from pepper to cocca is substantial　这个增强了观点，既然原始花费更高，而且现在pepper 贵，我还是不要换去种cocca了

C) supplies of pepper would not be as low as they are if those growers had not switched crops，答案

D) cocca crops are susceptible to being reduced by bad weather as are pepper crops　这个和天气没关系

E) as more growers turn to growing cocca, cocca supplies will increase and the price of cocca will fall precipitously. 如果都去种cocca,价格会减哦，所以还是不要换了

楼主给下答案？

Sorry i can not type chinese now!

The answer is C.

To Heslow: i understand your explanation now. But i chose A. Can you tell me why not A?Only because C is better than A?

题目说:

因为pepper价格增高，所以说，那些人(pepper种植者的一部分)选择从种pepper变成种cocca，还不如不换的好

for choice A

those growers could not have foreseen how high the price of pepper would go

不预见将来pepper的价格会涨到多高.，

既然我不知道会涨多高，那价格将来可能涨很多，也可能不涨。如果涨了，自然我是不如不换的好，可是不涨呢？嘿嘿，还是换一个其他的作物比较好，别的说不定能涨呢。

感觉和股票换仓的逻辑差不多。。喀喀
