单选题近代以来，史学界发展出几种“专门之学”，即简帛学、敦煌学、徽学、黑城学等，主要对象是出土或传世的文书，包括简帛文书、敦煌吐鲁番文书、徽州文书、黑城文书，时间跨度从战国秦汉直至明清。虽然这些研究的对象多是文书，中国却并没有自己的“古文书学”。原因当然是多方面的，其中一个重要原因，就是这些研究是随着出土或传世文书的不断发现而逐步扩大兴盛，却又各自为界。所以，只有在文书数量足够多、研究足够丰富、积累足够厚重、交流足够频繁的情况下，才有可能建立“中国古文书学”。
这段文字主要反映了史学界怎样的研究状况?______

单选题Pressure is mounting on Ahold"s embattled supervisory board following the Dutch grocery group"s decision to pay its new chief executive more than C= 10m to lead its recovery from a ruining accounting scandal.
Anders Moberg"s pay package—and the timing of its disclosure at a shareholder meeting last week—has confronted Ahold with a new credibility crisis as it struggles to restore confidence after the C=970m ( MYM1 bn) scandal.
The dispute—evident in a sea of critical media comment in the Netherlands at the weekend threatens to divert management from its recovery strategy, built on significant divestments and a likely rights issue to reduce C=11bn in net debt. Units deemed unable to attain first or second position in food retail within three to five years will immediately be put up for sale.
The board"s position appears all the more delicate following comments made by Mr. Moberg to the Financial Times, in which he criticized non—executive directors for ignoring his advice to disclose his salary in May, when he agreed his contract.
Instead Ahold waited more than four months to make the announcement, on the day share—holders were asked to approve Mr. Moberg"s appointment.
"I was the one who said I liked transparency, and I had hoped [the supervisory board] had shown [the salary package] in May to avoid a situation like this," Mr. Moberg told the FT.
As the row prompted the left—leaning Dutch Daily to call for a boycott of Ahold"s Dutch Albert Heijn supermarket chain where only last week Ahold announced 440 redundancies-it was clear the supervisory board had badly misjudged the reaction.
While Henny de Ruiter, supervisory board chairman, said the salary was a fair reflection of what a company in Ahold"s unfavorable circumstances had to pay to attract a top manager, furious investors accused it of pushing through the package regardless of investor opinion.
Furthermore, Dutch media commentators noted that the scandal at Ahold had been the trigger for the Dutch government to appoint a commission to strengthen corporate governance.
That commission has recommended a limit on executive bonuses, far below the potential two—and—a—half times annual salary that Mr. Moberg could earn.
Meanwhile, Mr. Moberg is trying to distance himself from the row and focus on strategy. He told the FT that measures had already been taken to raise its stake in the ICAA hold joint venture in Scandinavia.
Ahold had included in its forecasts an amount necessary to buy the shares of either of its joint venture partners, who should exercise a "put option" and sell their stake from April 2004.

单选题New reasearch from NASA scientists suggests emissions of black soot after the way sunlight reflects off snow. According to a computer simulation, black soot may be responsible for 25 percent of observed global warming over the past century.
Soot in the higher latitudes(维度)of the Earth, where ice is more common, absorbs more of the sun"s energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflects sunlight.
Soot in areas with snow and ice may play an important role in climate change. Also, if snow and ice covered areas begin melting, the warming effect increase, as the soot becomes more concentrated on the snow surface. "This provides a positive feedback, as glaciers and ice sheets melt, they tend to get even dirtier." said Dr. James Hansen, a researcher at NASA"s Goddard Institute for Space Studies, New York.
Hansen found soot"s effect on snow albedo(反照率), which may be contributing to trends toward early springs in the Northern Hemisphere, such as thinninbg Arctic sea ice and melting glaciers permafrost. Soot also is believed to play a role in changes in the atmosphere above the oceans and land.
"Black carbon reduces the amount of energy reflected by snow back into space, thus heading the snow surface more than if there were no black carbon," Hansen said. Soot"s increased absorption of solar energy is especially effective in warming the world"s climate." This forcing is unusually effective, causing twice as much global warming as a carbon-dioxide forcing of the same magnitude." Hansen noted.
Hansen cautioned, although the role of soot in altering global climate is substantial, it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century. Such gases are expected to bi the largest climate forcing for the rest of the century.
The researchers found that observed warming in the Northern Hermisphere was large in the winter and spring at middle and high latitudes. These observations were coherent with the researchers" climate model situations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.
