[单项选择] For most thinkers since the Greek philosophers, it was self-evident that there is something called human nature, something that constitutes the essence of man. There were various views about what constitutes it, but there was agreement that such an essence exists -- that is to say, that there is something by virtue of which man is man. Thus man was defined as a rational being, as a social animal, an animal that can make tools, or a symbol-making animal. More recently, this traditional view has begun to be questioned. One reason for this change was the increasing emphasis given to the historical approach to man. An examination of the history of humanity suggested that man in our epoch is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called "human nature". The historical approach was reinforced, particularly in the United States, by studies in the field of cultural anthropology (人类学). T
A. is the quality distinguishing man from other animals
B. consists of competitiveness and selfishness
C. is something partly innate and partly acquired
D. consists of rationality and undesirable behavior

[单项选择]11月8日上午，国防科技工业局首次公布了嫦娥二号卫星传回的嫦娥三号预选着陆区一一月球虹湾地区的局部影像图。它是一张黑白照片，成像时间为10月28日18时，是卫星在距离月面大约18.7千米地方拍摄获取的。摄像图的传回，标志着嫦娥二号任务所确定的六个工程目标已经全部实现，意味着“嫦娥二号”工程任务取得圆满成功。
嫦娥二号的发射，最主要的任务是对月球虹湾地区进行高清晰度的拍摄，为今后发射嫦娥三号卫星并实施着陆做好前期准备。
据悉，此次嫦娥二号携带的CCD相机分辨率比嫦娥一号携带的提高很多。嫦娥二号在100千米圆轨道运行时分辨率优于10米，进入100千米×15千米的椭圆轨道时，其分辨率达到1米，已超过了原先预定的1.5米的指标。据了解，将来嫦娥三号着陆器上也同样有CCD相机，届时它不光要拍照，还能根据图片自主避开着陆器在软着陆过程中不适于降落的地点，“临机决断”为着陆器选择适宜降落的平坦表面。
以下陈述中，最符合题干观点的是
A. 嫦娥二号拍摄的月球虹湾地区局部影像图传送到地球大约需要10天时间。
B. 对月球虹湾地区进行高清晰度的拍摄是嫦娥二号唯一任务。
C. 嫦娥二号在100千米的圆形轨道运行时拍摄了月球虹湾地区局部影像图。
D. 嫦娥二号在椭圆轨道绕月运行时拍摄了月球虹湾地区局部影像图。
E. 嫦娥二号在完成六项预定工程目标后失去了与陆地控制中心的联络。

根据下面内容，回答171-175题
Every product on the market has a variety of costs built into it before it is ever put up for saleto a customer．There are costs of production, transportation, storage, advertising, and more．Eachof these costs must bring in some profit at each stage : truckers must profit from transporting prod-
ucts, or they would not be in business．Thus, costs also include several layers of profits．The sell-ing price of a product must take all of these costs (and built in profits) into consideration．The sell-ing price itself consists of a markup over the total of all costs, and it is normally based on a per-centage of the total cost.
The markup may be quite high,90 percent of cost, or it may be low．Grocery items in a su-permarket usually have a low markup, while mink coats have a very high one．High markups,however, do not in themselves guarantee big profits．Profits come from turnover．If an item has a50 percent markup and does not sell, there is no profit
A. the buyers search from place to place for desired object
B. the government selects the best items
C. the government transacts with an individual
D. the sellers compete with each other for the bid
