防止气锁的方法中（）是无效的。A、放套管气生产 B、在泵的进口下面装气锚 C、控制套压，

在高科技时代，世界经济已是一个依靠知识驱动的智力系统。单纯模仿的时代结束了，这是一个发挥民族创造力的时代。科学技术已经变成了社会的核心资源，在一定意义上讲，物质资源也退居次要地位。最可贵的资源是智慧，财富的最高形式是科学技术知识。利用高科技开发的产品是“集成知识”型产品，而传统产品则属于“集成资源”型产品。集成知识型产品常常要求预先支付较高费用，但其实际成本则是微不足道的。因而带来巨额利润。例如购买一份软件可能要花几百万元，但拷贝这份软件只需几元钱，其实价与成本价的差额也比低技术产品高得多。一种产品越接近纯知识型，它的收益也就可能越高，广泛利用高科技成果可以大大减少对资源和能源的信赖程度。在以知识为基础的竞争中，“智能资本”带来的收益可以说是无止境的。“智能资本”最终将导致社会财富的大转移，即从[]的拥有者手里转移到那些掌握着[]的人手中。正因如此，当今物质资源贫乏的国家，只要充分掌握并有效地利用了科学技术知识，就可以发展成为经济上的强国。

对“广泛利用高科技成果可以大大减少对资源和能源的信赖程度”的原因分析正确的一项是（）

A．因为科学技术已变成了当今社会的核心资源

B．因为当今社会最可贵的资源是智慧

C．因为在以知识为基础的产品竞争中，“智能资本”带来的收益是无止境的

D．因为“智能资本”最终将导致世界财富的大转移

It has often been remarked that the saddest thing about youth is that it is wasted on the young. Reading a recent newspaper report on a survey conducted among college freshmen, I recalled the regret,

"If only I knew then what I know now."

The survey disclosed what I had already suspected from informal polls of students. According to the survey, which was based on the responses of over 188,000 students, today’s traditional-age college freshmen are" more materialistic and less altruistic".

41. ______. It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the" altruistic" fields is at a low, along with ethnic and women’s studies. On the other hand, enrollment in business programs, engineering and computer science is way up.

42. ______.

Frankly, I’m proud of the young lady (not her attitude but her success). But why can’t we have it both ways Can’t we educate people for life as well as for a career I believe we can. If we’re not, then that is a fault of our educational system--elementary, secondary and higher. In a time of increasing specialization, a time when 90 percent of all the scientists who have ever lived are currently alive, more than ever we need to know what is truly important in life.

43. ______.

Most of us finally come to realize that quality of life is not entirely determined by how much we earn. Sure, everyone wants to be financially comfortable, but we also want to feel that we have a perspective on the world beyond the confines of our occupation; we want to be able to render service to our fellow man and to the world.

44. ______.

It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs.

45. ______.

In the long run that’s what education really ought to be about. And I think it can be. That’s the way it should be. Oscar Wilde had it right when he said that we ought to give our ability to our work but our genius to our lives. Let’s hope our educators answer the students cries for career education, but at the same time, let’s ensure that the students are prepared for the day when they realize their folly. There’s a lot more to life than a job.

[A] Academic emphasis on competition, rationality and externals acknowledges only one kind of knowing. It makes students devalue their inner selves or larger social purposes.

[B] Not surprising in these hard times, the student’s major objective" is to be financially well off." Less important than ever is developing a meaningful philosophy of life.

[C] Education must meet the needs of the human spirit. It must assist students to develop a satisfactory personal philosophy and sense of values; to cultivate tastes for literature, music and the arts; to grow in ability to analyze problems and arrive at thoughtful conclusions.

[D] That’s no surprise either. A friend of mine (a sales representative for a chemical company)was making twice the salary of her college instructors during her first year on the job. And that was four years ago; She must be earning much more now.

[E] Most people, somewhere between the ages of 30 and 50, finally arrive at the inevitable conclusion that they could do more than serving a corporation, a government agency, or whatever.

[F] But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense.

[G] While it’s true that we all need a career, preferably a profitable one, it is equally true that our civilization has accumulated an incredible amount of knowledge -- be it scientific or artistic.
