“Commuter use of the new subway train is exceeding the transit company’s projections. However, commuter use of the shuttle buses that transport people to the subway stations is below the projected volume. If the transit company expects commuters to ride the shuttle buses to the subway rather than drive there, it must either reduce the shuttle bus fares or increase the price of parking at the subway stations.”

第一篇讲1800’ British business在亚洲做生意,很难用公开的数字来衡量这些business是否成功,股票的dividend也不能反映long-term经营的好坏。举了一个例子,说在印度的一家British 公司股票的dividend很高,其原因是Indian Rupee 汇率和tax,而不是公司经营的好。

 

第二篇讲用laser来鉴定油画的新方法(LMPD还是LPMD的,记不起来了)

 

第三篇较长,讲美国电影的早期发展,明星是如何产生的,一个是电影制作的演变和观众的需求。一开始电影制作各家都差不多,都是远镜头,观众不需要什么明星,后来出现一个patent pool,特写和近镜头出现了,明星也慢慢出现了。后来有一个z的人,打破了patent pool 电影制作方式,创立了一套新的电影制片和发行的方式,用对明星的发展产生了影响….

 

第四篇较短,讲一个人hyde研究一种叫M的恐龙化石,认为这种恐龙一孵出来是由母恐龙抚养的,因为小恐龙的leg上由一种骨头表明他们是蹲着的,同时发现小恐龙的牙齿有咬过东西的痕迹。然而又有两个科学家,发现另外一种叫H恐龙,HM的近亲,腿上都有这种骨头,表明hyde的发现不对的,但是H在孵化出来时牙齿就有磨损的痕迹,表明他们在孵出来之前就会磨牙(这考了一题)

GWD-29-Q40

Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream.  However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur.  These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.

 

Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

 

  1. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
  2. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
  3. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
  4. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
  5. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice.
