[填空题]
One Of the main causes of the earth’ s troubles is that the world is overpopulated and that this overpopulation is growing at an ever increasing rate. At the same time men are using up the natural resources at an ever growing rate with no hope of replacing them.

[简答题]
There are more rich people than ever before, including some 7 million millionaires, and over 400 billionaires. From sipping champagne to taking trips into space, they are getting plenty of pleasure—though as our survey of the new rich shows, these rich should have worries, too, not least about the damaging effect their wealth may have on their children. 61)As for the poor, the gap between them and the rich is rising, even in the industrialized countries where for much of the 20th century the gap had narrowed.

One patient, a fund analyst, came to me recently in a state of great anxiety. "It’s bad, but it might get a lot worse," I recall him saying. The anxiety was expected and appropriate: he had lost a great deal of his (and others’) assets, and like the rest of us he had no idea where the bottom was.
