GWD7-37对参考答案的疑惑

二狼神

Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high. Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business. With fewer suppliers, meat prices will surely rise. Nonetheless, observers expect an immediate short-term decrease in meat prices.

Which of the following, if true, most helps to justify the observers’ expectation?

1. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
           
2. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
           
3. Some people who ate meat regularly in the past are converting to diets that include little or no meat.
           
4. As meat prices rise, the number of livestock producers is likely to rise again.
           
5. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

看了之前的讨论贴都一边倒选B,但我觉得B是miss point.原文结论说供应减少与肉类价格的影响,B说"send...earlier"这里这个send跟销售/供应的意思还是不同的,只是表达运输的动作,运输到市场的时间早晚跟供应给市场的数量大小没有必然联系,所以B无关.

只有C说有些人对肉的消费量减少,这是真正对供需关系造成影响的.以前很多讨论都把重点放在C能否表达一个原文说的"immediate short-term "的意思上,觉得C没这意思而否定它.我觉得C用了现在分词就已经清楚地表达了一个immediate的状态,用some people跟原文的worldwide demand 进行对比已经清楚表达了short-term的意思,所以只有C是正确的.请大家指教!

我选E

能说说对E的看法吗?不过最好能说说C为何不对?B为何不对?

Nonetheless, observers expect an immediate short-term decrease in meat prices.

很快就降价

E.Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past

用其他的东西喂，那么。。。玉米就没影响了

而且时间上有衔接

所以我选E

欢迎批评

玉米是没影响了,但E没说the feed other than corn比玉米贵呢还是便宜呢?

用得 more extensively 不等于这些新饲料的价格必然cheaper than corn呀,还有很多其他原因可以导致这个代替的发生的.所以E是无法支持decrease in meat prices.

当然如果你觉得只有价格便宜才是唯一的理由来替换饲料的话....

答案不需要是充分条件啊，所以您的反驳不成立。

另外，GWD是否100％是真题也值得商榷。所以，不需要在每个题目上面耗费这么多时间。

还是念OG最好。

就是说如果答案不需要选项是充分条件,所以只要一个选项它是充分条件它就肯定错?

是啊,包括在实战的时候.我会争取把整体时间安排好的,争议题在最后我会按最能接受的答案来看.现在主要是模考GWD,OG主要是拿来做横向总结用.
