[单项选择]The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B. C., followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable.
The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated.
These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when

[简答题] Programming languages are how people talk to computers. The computer would be just as happy speaking any language that was unambiguous. The reason we have high level languages is because people can’’t deal with machine language. The point of programming languages is to prevent our poor frail human brains from being overwhelmed by a mass of detail.
Architects know that some kinds of design problems are more personal than others. One of the cleanest, most abstract design problems is designing bridges. There your job is largely a matter of spanning a given distance with the least material. The other end of the spectrum is designing chairs. Chair designers have to spend their time thinking about human bodies. Software varies in the same way. Designing algorithms (运算法则) for routing data through a network is a nice, abstract problem, like designing bridges. Whereas designing programming languages is like designing chairs: it’’s all about dealing with human weaknesses.

[简答题]Into the Unknown
The world has never seen population ageing before. Can it cope
Until the early 1990s nobody much thought about whole populations getting older. The UN had the foresight to convene a “world assembly on ageing” back in 1982, but that came and went. By 1994 the World Bank had noticed that something big was happening. In a report entitled “Averting the Old Age Crisis”, it argued that pension arrangements in most countries were unsustainable.
For the next ten years a succession of books, mainly by Americans, sounded the alarm. They had titles like Young vs Old, Gray Dawn and The Coming Generational Storm, and their message was blunt: health-care systems were heading for the rocks, pensioners were taking young people to the cleaners, and soon there would be intergenerational warfare.
Since then the debate has become less emotional, not least because a lot more is known about the subject. Books, conferences and research papers have multiplied. International organ
