Search on the Computer

What difference does it make if we read texts displayed on a computer screen instead of on paper printed with ink? The computer certainly does not guarantee deeper comprehension, greater subtlety of mind, or a wider range of imaginative reference. The mediation of a computer, however, put new powers at the disposal of intelligence. For one thing, the computer is itself can do simple reading—as I have noted, it can" read" an immense body of literature in search of designated words. As anyone knows who has ever spent days in libraries in search of errant(错误的) information, simply identifying relevant sources absorbs inordinate(无节制的，过度的)amounts of time in research. The objections might be raised that a search of texts by computer may block the serendipitous(偶然得到的 ) discoveries that occur while browsing in the stacks of great libraries. No member of the academy need fear that the use of computer will keep him from the stacks, but browsing is, if anything, easier if texts can be called up on a screen in the senerity of one's chosen surroundings,
The great deficiency of libraries, as we know them, is that while titles are catalogued, the libraries have no master indexes of the contents of books. Individual volumes, it is true, have indexes, often of inferior quality, but even the best indexes must be examined one at a time. The great advantage of the electronic library is that a computer could search and analyze its contents without proceeding volume by volume. As work in artificial intelligence develops, computer systems may also become adept at more complex tasks, such as summarizing texts, which has been accomplished experimentally.

单选题 What is the passage mainly about?

【正确答案】 A

【答案解析】开篇首先指出了在电脑屏幕上的阅读并不会比阅读纸质材料更有益处，但是接下来很快切入主题：利用电脑搜索文档查找我们需要的信息可以节省很多时间。在第二段主要论述了在图书馆中利用电脑检索信息与传统的检索方法相比的好处。所以全篇都在讲述利用计算机查找信息的好处，因此正确答案为A。

单选题 The word" literature" ( line 5, paragraph 1 ) is refers to

【正确答案】 C

【答案解析】分析一下所考查的词汇所在的句子：it can "read" an immense body of literature in search of designated words(它可以“阅读”很长的______来搜索指定的词语)，而且阅读该旬前后的内容也没有发现任何对计算机所阅读内容作出任何限制，因此这里的literature并不是指特定的文字内容，而是所有的书写下来的文字，因此本题的正确答案为C。

单选题 The advantage of reading by the computer over reading on paper lies in that it

【正确答案】 D

【答案解析】文章一开篇就指出，在电脑屏幕上阅读既不会保证我们对文字内容有更深的理解，也不会增加大脑的敏感性或者拓宽想象范围。所有前三个选项都不是正确答案。D项内容也可以在第一段的第四句中找到根据：it can "read"　an immense body of literature in search of designated words(它可以阅读很长的文字来搜索指定的词汇)，而第五句又指出有在图书馆花费数天检索信息的经历的人都知道，单单是确认相关内容的来源就会耗费大量的时间，由此我们可知，利用计算机检索信息能够节省大量的时间。

单选题 Computer systems will work better in the future

【正确答案】 A

【答案解析】根据题干关键词computer system和in the future定位到文章的结尾处：As work in artificial intelligence develops, computer systems may also become adept at more complex tasks，(随着人工智能的发展，计算机系统可能也会在处理更加复杂的任务时更加熟练)，由此可知本题的正确答案为A。
