[单项选择]

In every British town, large and small, you will find shops that sell second-hand goods. Sometimes such shops deal mostly in furniture, sometimes in books, sometimes in household goods, sometimes even in clothes.
The furniture may often be "antique" and it may well have changed hands many times. It may also be very valuable, although the most valuable pieces will usually go to the London salerooms, where one piece might be sold for hundreds of thousands of pounds. As you look around these shops and see the polished(擦亮的) wooden boxes and tables, you can’t help thinking sadly of those long—dead hands which polished that wood, of those now—closed eyes which once looked at these pieces with love.
The books, too, may be antique and very valuable; some may be rare first printings. Often when someone dies or has to move to a new place his books may all be sold, so that sometimes you may find whole libraries in one shop. On the border be

American Indian Movement (AIM) is an organization devoted to promoting cultural awareness and political self-determination for Native Americans. AIM seeks recognition of treaty rights in accordance with agreements between Native American tribes and the United States government. The organization also supports Native American education and cultural programs. AIM is best known for its confrontational political demonstrations during the late 192s and 1970s.
AIM was founded in 1968 in Minneapolis, Minnesota, in response to complaints by Native American residents about police brutality. Members of the organization began to monitor police behavior. As the group gained strength, they also started to lobby for improved city services for the many Native Americans living in run-down tenant apartments, and they developed survival schools where Native American youths could be taught about their culture. Over the next four

C. To appeal to the people to invest more money on the Native American.

Most scholars agree that Isaac Newton, while formulating the laws of force and gravity and inventing the calculus in the late 1600s, probably knew all the science there was to know at the time. In the ensuing 350 years an estimated 50 million research papers and innumerable books have been published in the natural sciences and mathematics. The modern high school student probably now possesses more scientific knowledge than Newton did, yet science to many people seems to be an impenetrable mountain of facts.
One way scientists have tried to cope with this mountain is by becoming more and more specialized. Another strategy for coping with the mountain of information is to largely ignore it. That shouldn’t come as a surprise. Sure, you have to know a lot to he a scientist, but knowing a lot is not what makes a scientist. What makes a scientist is ignorance. This may sound ridiculous, but for scientists the facts are just a starting place. In science, every new discover
A. A scientist is a master of knowledge
B. Knowledge generates better ignorance
C. Ignorance is a sign of lack of education
D. Good scientists are thoroughly ignorant
