1. 午睡15分钟效率高
一个公司发现中午睡十五分钟可以提高员工工作效率,理由是虽然少了十五分钟,但睡醒后的工作效率可以变成原来的两倍(大概),然后就建议所有员工中午take 15 minutes 的nap,然后削弱
总工作量也加倍了 或者更多了 ,总工作量/时间=效率
2. 减少的鳄鱼
Parland's alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a species of freshwater fish that is highly valued as food by Parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption. Yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased.
Which of the following, if true, most helps to explain the decline in the population of the fish species?
(A) The decline in the alligator population has meant that fishers can work in some oarts of lake sand rivers that were formerly too dangerous.
(B) Over the last few years, Parland's commercial fishing enterprises have increased the number of fishing boats they use.
(c) The main predator of these fish is another species of fish on which alligators also prey.
(D) Many Parlanders who hunt alligators do so because of the high market price of alligator skins, not because of the threat alligators pose to the fish population.
(E) In several neighboring countries through which Parland's rivers also flow, alligators are at risk of extinction as a result of extensive hunting.
C 鳄鱼吃某鱼的天敌,鳄鱼少了,天敌多了,某鱼少了
3. 员工的医疗保险(有点扯的外因)
公司为了减低员工医保支出,告诉员工少看病,但费用仍然上升,为什么?
没看懂,员工数量上升了吗?单个员工少看病费用少
