he United States will no longer be a great foodexporting nation and that，if necessity forces exports，it will be at the price of belttightening at home.
In fact，as food items will end to decline in quality and decrease in variety，there is very likely to be incresing use of flavouring additives.（75）Until such time as mankind has the sense to lower its population to the point where the planet can provide a comfortable support for all，people will have to accept moreunnatural food.

事实是，虽然官方是突然宣布能源危机的存在，然而长期以来我们一直面临着能源危机，而且这种情况今后将会持续更长的时间。不管阿拉伯的石油能否源源不断地外流，人人都清楚，再也不能让世界工业依赖于如此脆弱的能源基础。（71）石油供应可能随时会被切断;不管怎样，以目前这种消费速度，只需30年左右，所有的油井都会枯竭。
（72）必须找到新的能源，这需要时间;而过去我们感觉到的那种能源廉价而充足的情况将不大可能再出现了。在今后的漫长的时间内，人类将谨慎前进，而它感到幸运的是它确实能够前进。
使目前状况糟糕的是，至今尚无迹象表明，世界人口的增长在近期内会减慢。虽然包括美国在内的一些国家的出生率已经下降，但是在21世纪初世界人口似乎肯定会超过60亿，或许甚至超过70亿。
（73）食品供应的增加将远远赶不上人口的增长，这就意味着我们在粮食的生产和购销方面已陷入危机。
考虑到所有这些因素，我们可以适当地估计一下2001年的超级市场将会是什么样子呢?首先，今后的30年内，世界的食品供应日益紧张，甚至美国这里也不例外。到2001年美国人口将至少达到2亿5千万，也可能是2亿7千万。那时，美国将很难扩大食品生产来满足人口增长的需要。（74）这种困境将是确定无疑的，因为能源的匮乏使农业无法以高能消费这种美国耕作方式继续下去了，而这种耕作方式可以投入少数农民就获得高产。
几乎可以肯定，到2001年美国将再也不是一个食品输出国;如果必须出口的话，那么其代价就是美国国内人民将勒紧裤带。
实际上，由于各种食品往往会质量下降、品种减少，这就有可能更多地使用调味添加物。（75）除非人类终于意识到要把人口减少到这样的程度，使地球能为所有人提供足够的饮食，否则人们将不得不接受更多的人造食品。

Intellingenceat best is an assumptive construct—the meaning of the word has never been clear.（71）There is more agreement on the kinds of behavior referred to by the term than there is on how to interpret or classify them.But it is generally agreed that a person of high intelligence is one who can grasp ideas readily，make distinctions，reason logically，and make ue of verbal and mathematical symbols in solving problems.An intelligence test is a rough measure of a child’s capacity for learning the kinds of things required in school.It does not measure character，social adjustment，physical endurance，manual skills，or artistic abilities.It is not supposed to—it was not designed for such purposes.（72）To criticise it for such failure is roughly comparable to criticising a thermometer for not measuring wind velocity.
The other thing we have to notice is that the assessment of the intelligence of any subject is essentially a comparative affair.
（73）Now since the assessment of intelligence is a comparative matter we must be sure that the scale with which we are comparing our subjects provides avalidorfaircomparison.It is here that some of the difficulties which interest us begin.Any test performed involves at least three factors:the intention to do one’s best，the knowledge required for understanding what you have to do，and the intellectual ability to do it.（74）The first two must be equal for all who are being compared，if any comparison in terms of intelligence is to be made.In school populations in our culture these assumptions can be made fair and reasona
