【单选题】If pollution continues to increase at the present rate, formation of aerosols in the atmosphere will cause the onset of an ice age in about fifty years’ time. This conclusion, reached byDr. S. I. Rasool andDr. S.H. Schneider of the United States Goddard Space FlightCentre, answers the apparently conflicting questions of whether an increase in the carbon dioxide content of the atmosphere will cause theEarth to warm up or increasing the aerosol content will cause it to cool down. TheAmericans have shown conclusively that the aerosol question is dominant.
Two specters haunting conservationists have been the prospect that environmental pollution might lead to the planet’s becoming unbearably hot or colD、One of these ghosts has now been laid, because it seems that even an increase in the amount of carbon dioxide in the atmosphere to eight times its present value will produce an increase in temperature of only 2 ℃, which would take place over several thousand years.But the other problem now looms larger than ever.
Aerosols are collections of small liquid or solid particles dispersed in air or some other medium. The particles are all so tiny that each is composed of only a few hundred atoms.Because of this they can float in the air for a very long time. Perhaps the most commonly experienced aerosol is industrial smog of the kind that plagued London in the 1950s and is an even greater problem in LosAngeles today. These collections of aerosols reflect the Sun’s heat and thereby cause theEarth to cool.
Dr. Rasool andDr. Schneider have calculated the exact effect of a dust aerosol layer just above theEarth’s surface in the temperature of the planet.As the layer builds up, the present delicate balance between the amount of heat absorbed from the Sun and the amount radiated from theEarth is disturbeD、The aerosol layer not only reflects much of the Sun’s light but also transmits the infrared radiation from below. So, while the heat input to the surface drops, the loss of heat remains high until the planet cools to a new balanced state. Within fifty years, if no steps are taken to stop the spread of aerosols in the atmosphere, a cooling of theEarth by as much as 3.5 ℃ seems inevitable. If that lasts for only a few years it would start another ice age, and because the growing ice caps at each pole would themselves reflect much of the Sun’s radiation it would probably continue to develop even if the aerosol layer were destroyeD、
The only bright spot in this gloomy forecast lies in the hope expressed byDr. Rasool andDr. Schneider that nuclear power may replace fossil fuels in time to prevent the aerosol content of the atmosphere from becoming critical.
Aerosols can float in the air for a very long time in that they ______.
A、can result in industrial smog
B.are liquid particles
C.are dispersed in air
D.are composed of tiny articles

【单选题】Archaeology has long been an accepted tool for studying prehistoric cultures. Relatively recently the same techniques have been systematically applied to studies of the more immediate past. This has been called "historical archaeology," a term that is used in the United States to refer to any archaeological investigation into NorthAmerican sites that postdate the arrival ofEuropeans.
Back in the 1930’s and 1940’s, when building restoration was popular, historical archaeology Was primarily a tool of architectural reconstruction. The role of archaeologists was to find the foundations of historic buildings and then take a back seat to architects.
The mania for reconstruction had largely subsided by the 1950’s and 1960’s. Most people entering historical archaeology during this period came out of university anthropology departments, where they had studied prehistoric cultures. They were, by training, social scientists, not historians, and their work tended to reflect this bias. The questions they framed and the techniques they used were designed to help them understand, as scientists, how people behaveD、But because they were treading on historical ground for which there was often extensive written documentation, and because their own knowledge of these periods was usually limited, their contributions toAmerican history- remained circumscribeD、Their reports, highly technical and sometimes poorly written, went unreaD、
More recently, professional archaeologists have taken over. These researchers have sought to demonstrate that their work can be a valuable tool not only of science but also of history, providing fresh insights into the daily lives of ordinary people whose existences might not otherwise be so well documenteD、This newer emphasis on archaeology as social history, has shown great promise, and indeed work done in this area has lead to a reinterpretation of the United States past.

The author mentions an excavation at the site of a hotel in Sacramento in order to give an example of ______.
A、a building reconstruction project
B.the work of the earliest historical archaeologists
C.a finding that conflicts with written records
D.the kind of information that historians routinely examine
