问题 问答题 案例分析题

材料一“我不知道世人对我是怎样看法,但是在我看来,我不过象一个在海滨玩耍的孩子,为时而发现一块比平常光滑的石子或美丽的贝壳而感到高兴;但那浩瀚的真理之海洋,却还在我的面前未曾发现呢?”

——牛顿

材料二德国著名的物理学家普朗克年轻时曾向他的老师表示要献身于理论物理学,老师劝他说:“年轻人,物理学是一门已经完成了的科学,不会再有多大的发展了,将一生献给这门学科,太可惜了。”19世纪理论物理学达到了巅峰状态,但其中也隐含着巨大的危机。海王星的发现显示出牛顿力学无比强大的理论威力,电磁学与力学的统一使物理学显示出一种形式上的完整,并被誉为“一座庄严雄伟的建筑体系和动人心弦的美丽的庙堂”。在人们的心目中,古典物理学已经达到了近乎完美的程度。

材料三两位决定时代发展的科学家和他们的成果

材料四

材料二告诉我们,19世纪近乎完美的经典物理学也“隐含着巨大的危机”,普朗克是如何解决这个难题的?

答案

参考答案:

提出了量子假说;

解析:本题考查了量子论的提出及其影响。旨在考查学生再认、再现所学知识答题的能力。由设问中的“19世纪……经典物理学……隐含着巨大的危机”“普朗克……解决”可知这应为1900年,德国物理学家普朗克提出了量子论。

单项选择题

Shopping has always been something of an impulse activity, in which objects that catch our fancy while strolling are immediately bought on a whim. Advertisers and sellers have taken advantage of this fact, carefully positioning inexpensive but attractive items on paths that we are most likely to cross, hoping that our human nature will lead to a greater profit for them. With the dawn of the Internet and its exploding use across the world, the same tactics apply.

Advertisers now place "banners", links to commercial web sites decorated with attractive pictures designed to catch our eyes while browsing the webs, on key web sites with heavy traffic. They pay top dollar for the right, thus creating profits for the hosting web site as well. These actions are performed in the hopes that during the course of our casual and leisurely web surfing, we’ll click on that banner that sparks our interest and thus, in theory, buy the products advertised.

Initial results have been positive. Web sites report a huge inflow of cash, both from the advertisers who tempt customers in with the banners and the hosting web sites, which are paid for allowing the banners to be put in place. As trust and confidence in Internet buying increases and information security is heightened with new technology, the volume of buying is increasing, leading to even greater profits.

The current situation, however, is not quite as optimistic. Just as magazine readers tend to unconsciously ignore advertisements in their favorite periodicals, web browsers are beginning to allow banners to slip their notice as well. Internet users respond to the flood of banners by viewing them as annoyances, a negative image that is hurting sales, since users are now less reluctant to click on those banners, preferring not to support the system that puts them in place. If Internet advertising is to continue to be a viable and profitable business practice, new methods will need to be considered to reinvigorate the industry.

With the recent depression in the technology sector and slowing economy, even new practices may not do the trick. As consumers are saving more and frequenting traditional real estate businesses over their Internet counterparts, the fate of Internet business is called into question. The coming years will be the only reliable indication of whether shopping on the world wide web is the wave of the future or simply an impulse activity whose whim has passed.

Analyzing the current state of the online advertising in paragraph 4, the author implies that()

A. it has to be modified over time to remain effective

B. for all its current profits, it will fade in the long run

C. banners are beginning to lose their advertising efficiency

D. Internet advertising methods will continue to decrease sales
