SECTION B ENGLISH TO CHINESE
Directions: Translate the following text into Chinese.
Most people complain of fortune, few of nature; and the kinder they think the latter has been to them, the more they murmur at what they call the injustice of the former.
Why have not I the riches, the rank, the power, of such and such, is the common expostulation with fortune; but why have not I the merit, the talents, the wit, or the beauty, of such and such others, is a reproach rarely or never made to nature.
The truth is, that nature, seldom profuse, and seldom niggardly, has distributed her gifts more equally than she is generally supposed to have done. Education and situation make the great difference. Culture improves, and occasions elicit, natural talents. I made no doubt but that there are potentially, if I may use that pedantic word, many Bacons, Lockes, Newtons, Caesars, Cromwells, and Marlboroughs at the ploughtail, behind counters, and, perhaps, even among the nobility; but the soil must be cultivated, and the season favourable, for the fruit to have all its spirit and flavour.

Pudong New Area is part of the city of Shanghai. It is located on the eastern side of Huangpu River, which cuts through the city. Pudong has a laud area of 533.@44 square kilometers and a permanent population of 163 million. In the past, due to the lack of bridges and tunnels across the river, Pudong lagged far behind the old downtown of Shanghai in terms of economic growth, though it lies just opposite the latter.
On April 18, 1990, the Chinese central government made the announcement of opening up and developing Shanghai Pudong. That was seen as a major strategy to turn Shanghai into one of world's largest economic, financial and trade centers and to regenerate the economy of the Yangtze River Delta and even the whole Yangtze River Valley.
The reconstruction of Pudong is a major strategic decision in carrying on the social and economic progress of China. It will lead the country in innovations of administrations, upgrading of industrial structures and expanding the practice of the opening-up policy. The past ten years have witnessed explosive economic growth in Pudong as well as an enormous change in the appearance of the city. Pudong New Area has become the landmark of Shanghai as one of the international economic centers in the 21st century.
As the tallest building in China, Jin Mao Tower is au intelligent building offering services for business, hotel, recreation, sightseeing and shopping. It is not only a new tourist attraction but also a window through which people from other parts of the world may get a better understanding of Shanghai and Pudong.
