问答题For most of human history, the dominant concerns about energy have centered on the benefit side. Inadequacy of energy resources of the technologies for harvesting, converting, and distributing those resources has meant insufficient energy benefits to human beings and hence inconvenience, and constraints on its growth. The 1970"s, then, represented an turning point. Energy was seen to be getting costlier in all respects. It began to be believable that excessive energy costs could pose threats on a par with those of insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits. The crucial question at the beginning of the 1990"s is whether the trend that began in the 1970"s will prove to be temporary or permanent. Is the era of cheap energy really over, or will a combination of new resources, new technology and changing geopolitics bring it back? One key determinant of the answer is the staggering scale of energy demand brought forth by 100 years of population growth and industrial demand. Except for the huge pool of oil underlying the Middle East, the cheapest oil and gas are already gone. Even if a few more giant oil fields are discovered, they will make little difference against consumption on today"s scale. Oil and gas will have to come increasingly, for most countries, from deeper in the earth and from imports whose reliability and affordability cannot be guaranteed.

问答题Remember, my son, you have to work. Whether you handle a pick or a pen, a wheel-barrow or a set of books, digging ditches or editing a paper, ringing an auction bell or writing funny things, you must work. If you look around you will see the men who are the most able to live the rest of their days without work are the men who work the hardest. Don't be afraid of killing yourself with overwork. It is beyond your power to do that on the sunny side of thirty. They die sometimes, but it is because they quit work at six in the evening, arid do not go home until two in the morning. It's the interval that kills, my son. The work gives you an appetite for your meals; it lends solidity to your slumbers, it gives you a perfect and grateful appreciation of a holiday. There are young men who do not work, but the world is not proud of them. It does not know their names, even it simply speaks of them as "old so-and-so's boy." Nobody likes them; the great, busy world doesn't know that they are there. So find out what you want to be and do, and take off yore coat and make a dust in the world. The busier you are, the less harm you will be apt to get into, the sweeter will be your sleep, the brighter and happier your holidays, and the better satisfied will the world be with you.
