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.

The writer’s attitude towards use of computer in reading can be described as()

American public education has changed in recant years. One change is that increasing numbers of American parents and teachers are starting independent public schools (51) charter schools (特许学校).
In 1991, there were no charter schools in the United States. Today, more than 2,300 charter schools (52) in 34 states and the District of Columbia. 575,000 students (53) these schools. The students are from 5 years of age through 18 or older.A charter school is (54) by groups of parents, teachers and community (社区) members. It is similar in some ways (55) a traditional public school. It receives tax money to operate just as other public schools do. The (56) it receives depends on the number of students. The charter school must prove to local or state governments that its students are learning. These governments (57) the school with the agreement, or charter that permits it to operate.
Unlike a traditional public school, (58) , the charter school does not have to obey most laws governing public schools. Local, state or federal governments cannot tell it what to (59) .
Each school can choose its own goals and decide the ways it wants to (60) those goals. Class sizes usually are smaller than in many traditional public schools. Many students and parents say (61) in charter schools can be more creative.
However, state education agencies, local education-governing committees and unions often (62) charter schools. They say these schools may receive money badly (63) by traditional public schools. Experts say some charter schools are doing well while others are struggling.
Congress provided 200 million dollars for (64) charter schools in the 2002 federal budget (预算). But, often the schools say they lack enough money for their (65) . Many also lack needed space.
