Energy Crisis{{/B}} One key question for the next century is how we provide energy in an environmentally sound way. As living standards rise in the developing world, energy consumption will increase. As a result, many countries are now opening the door for private investment in a sector that used once to be solely the preserve of government. In the developed world, the move is towards the deregulation and privatization of electricity generation and distribution. There is also a trend towards locally-generated energy, particularly in the developing world. Factories and shopping centers may one day have their own power sources. Progress is also being made in minimizing the environmental impact of energy production and consumption. A A. How to save as much energy as possible. B. How to restrict the use of nuclear energy. C. How to provide energy in an environmentally sound way. D. How to get alternative way to motor cars. [单选题]支付系统行号由多少位组成（）。

It is often difficult for a man to be quite sure what tax (税) he ought to pay to the government because it depends on so many different things: whether the man is married; how many children he has; whether he supports any relations; how much he earns; how much interest he receives; how much he has spent on his house during the year; and so on and so forth. All this makes it difficult to decide exactly how much the tax is. [单项选择]Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.
Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don’’t threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’’ll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’’t be cheap.
Is it worth it Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400,000 years. Sounds pretty
