问题     The physicist investigating the relationship between time and space, the chemist exploring the properties of a new substance, the biologist probing the mysteries of the continuity of life, and the anthropologist searching for human origins share a common trait of curiosity. Not that non-scientists are not curious, most people possess this characteristic. The scientist, however, uses a specific method to make research into these enigmatic (如谜的, 难以理解的) problems— the scientific method.
    Unfortunately, science and its method are misunderstood. The multiplication of our knowledge in medicine and technology has led to the idea that science can cure all and explain all and that only enough time, money and intelligence are needed. In truth, science cannot provide all answers. In fact, many phenomena are not even subject to scientific explanations.
    On the other side of the coin, science has been attacked as a cause of most contemporary problems. It is said to be responsible for the depersonalization (人格解体,人性丧失) of the individual, for stripping creativity from human behavior, and for creating massive threats to the species through the development of nuclear power, insecticides, and polluting machinery. If we analyze the situation, we can see that it was not the original intent of the people who developed computers to debase humankind, nor was mass production proposed as a method to crush creativity. It is what society, policymakers especially, does with scientific achievements that makes them social or antisocial. There is nothing inherently good or bad about science.  
What does the expression "to debase humankind" in Para. 3 mean?

选项 A、To provide base to humankind.
B、To reduce the value of humankind.
C、To get rid of humankind.
D、To compete with humankind.

答案B

解析 本题是一道词汇含义类问题。问第三段中的debase humankind是什么意思。我们可以根据构词法和上下文推断出此词的含义。文章指出,另一方面,科学又被指责为众多的时弊之源。有人说科学造成了人们个性的丧失,剥夺了人类行为的创造性,通过开发核能、制造杀虫剂及造成污染的机械,对物种造成了巨大的威胁。如果分析一下这一情形,我们就会明白,人们研制计算机、搞大规模生产的初衷并不是贬低人类,也不是用以毁灭创造力。因此,本题的正确答案应是B“降低人类的价值”。
