单项选择题

There is no question that the academic enterprise has become increasingly global, particularly in the sciences. Nearly three million students now study outside their home countriesa 57% increase in the last decade. Foreign students now dominate many U.S. doctoral programs, accounting for 64% of Ph. D. s in computer science, for example.
Faculty members are on the move, too. Half of the world’s top physicists no longer work in their native countries. And major institutions such as New York University are creating branch campuses in the Middle East and Asia. There are now 162 satellite campuses worldwide, an increase of 43% in just the past three years.
At the same time, growing numbers of traditional source countries for students from South Korea to Saudi Arabia (沙特阿拉伯), are trying to improve both the quantity and quality of their own degrees, engaging in a fierceand expensiverace to recruit students and create world-class research universities of their own.
Such competition has led to considerable hand-wringing in the West. During a 2008 campaign stop, for instance, then—candidate Barack Obama expressed alarm about the threat that such academic competition poses to U. S. competitiveness. Such concerns are not limited to the United States. In some countries, worries about educational competition and brain drains have led to academic protectionism. India, for instance, places legal and bureaucratic barriers in front of Western universities that want to set up satellite campuses to enroll local students.
Perhaps some of the anxiety over the new global academic enterprise is understandable, particularly in a period of massive economic uncertainty. But educational protectionism is as big a mistake as trade protectionism is. The globalization of higher education should be embraced, not fearedincluding in the United States. There is every reason to believe that the worldwide competition for human talent, the race to produce innovative research, the push to extend university campuses to multiple countries, and the rush to train talented graduates who can strengthen increasingly knowledge-based economies will be good for the United States, as well.

Academic protectionism is characterized by ______.

A. enlarging enrollment of local students
B. limiting the growth of Ph.D. programs
C. creating more satellite campuses abroad
D. restricting satellite campuses of foreign universities

阅读下面短文，回答下 * * 道问题。
随着三峡文物考古工作的不断深入，峡江地区文明起源、发展，史前文化的脉络已开始清晰地展现在世人面前。考古学家兴奋地发现，三峡考古实际上是在长江流域打开一部可与黄河流域相媲美的“中国二十四史”，从它们之间交相辉映、交流融合的一件件文化遗存中，中华文明的生命活力、包容百川的基因图谱清晰可辨。
1999年，重庆考古队在丰都高家镇、烟墩堡发现多处旧石器时代遗址，一下将三峡地区的旧石器文化向前推了5万～10万年。从1994年的调查开始，库区共找到50多处旧石器遗存的地点，其中14处还保留着原生地层，在丰都高家镇还发现一处露天石器制作工场。
进入三峡地区的考古队还找到5000多年前后的部落遗址80多处。令考古学家兴奋的是，在湖北、湖南广泛分布的大溪文化、屈家岭文化和石家河文化遗存也存在于忠县哨棚嘴文化遗址中。新的考古发现说明，先民在新石器时代甚至更早就已经在峡江地区打通了一条文化走廊，三峡库区正是中原文化与楚文化交融的一个重要通道。
巴人是三峡库区的先民，大约存在于夏商至西周时期。三峡库区夏商至西周的考古发现大大改变了人们过去对这一段早期巴人文化知之甚少的状况，已经发现的巴人遗址和墓地已达百余处，使巴人文化从商周到战国形成一个不间断的完整序列。1996年以来，在巫山县紧邻大宁河东北侧发现的双堰塘遗址，忠县发现的中坝、哨棚嘴、瓦渣地等遗址群，云阳小江之侧的李家坝遗址和墓地，面积都达数万平方米，内涵丰富，是商至汉初时期巴人的中心活动地带。人们在这里发现了大量巴人的建筑、冶金、窑业遗址，可以说已经打开了深入研究巴人社会的神秘之门，巴人的历史面纱正在逐渐揭开。
走进库区一个个设施简陋的文物仓库，一件件青铜器、漆器、陶器令人眼花缭乱，不得不惊叹我们祖先高超的创造技艺。到目前为止，仅三峡重庆库区出土的珍贵文物就达上千件，出土一般文物上万件。
三峡的文物古迹，上下数万年。这是在特殊的地理环境和自然风光中形成的一长串历史遗痕。深入研究它们，可以提高今后如何更好地建设三峡地区的认识；认真思考它们，可以增加对三峡历史的敬意。

根据文意，对第一段的理解不正确的一项是______。

A．此段运用打比方、作比较的说明方法，形象地说明了长江流域和黄河流域一样古老，都是中华文明的发祥地

B．长江流域是继黄河流域之后，经我国考古工作者发现的中华文明的另一个重要发祥地

C．三峡地区史前文化的成就充分说明，峡江地区是继长江流域、黄河流域之后中华古文化的又一个重要的分布地区

D．长江流域和黄河流域两大文明有联系、有交融，我们从中可以看到中华文明的生命活力、包容百川的基因图谱
