Day 18
1. 老鼠大脑实验
研究表明,压力会导致老鼠大脑的一个区域变小。科学家们研究了因为压力而导致disorder的人,发现他们的那个区域也变小了。结论是,压力对于这块区域的作用在老鼠身上和在人身上是一样的。evaluate题。
P:老鼠和人都因为压力变小了
C:压力对于这块区域的作用在老鼠身上和在人身上是一样的
Evaluate:
- 原理:是否压力导致某个Disorder,而disorder才导致了变小的真原因;
- 因果关系:因果方向:不是因为变小了所以产生了压力;直接因果关系:非压力而disorder的人,是否变小了?
2. 产量低的时候存冰箱
Which of the following most logically completes the passage?
Pecan growers get a high price for their crop when pecans are comparatively scarce, but the price drops sharply when pecans are abundant. Thus, in high-yield years, growers often hold back part of their crop in refrigerated warehouses for one or two years, hoping for higher prices in the future. This year's pecan crop was the smallest in five years. It is nonetheless quite possible that a portion of this year's crop will be held back, since_________
(A) each of the last two years produced record-breaking pecan yields
(B) the quality of this year's pecan crop is no worse than the quality of the pecan crops of the
previous five years
(C) pecan prices have not been subject to sharp fluctuations in recent years
(D) for some pecan growers, this year's crop was no smaller than last year's
(E) the practice of holding back part of one year's crop had not yet become widespread the last time the pecan crop was as small as it was this year
C:It is nonetheless quite possible that a portion of this year's crop will be held back
Support:
原理:讲述为什么需要hold back:因为前两年多了(所以有所保留)

3. 灯泡vs灯泡
一种F打头的灯泡怎么怎么着,然后LED灯泡比起它来,持续时间长是它的5倍,价钱大概也是它的五倍(一个LED灯泡可以买5个F灯泡),问以上最有可能得出什么结论?
选项:
①F灯泡应该改进技术,增加与LED灯泡的竞争力;
②LED灯泡应该减价,增加与F灯泡的竞争力;
③LED灯可以用在换灯泡比较难的地方。
时间长 -> 不需要经常更换 选C
