对于素材中用黑体字的部分，特别建议你熟读，背诵，因为它们在语言和观点上都值得吸收。学习语言的人应该明白，表达能力和思想深度都靠日积月累，潜移默化。从某种意义上说，提高英语写作能力无捷径可走，你必须大段背诵英语文章才能逐渐形成语感和用英语进行表达的能力。这一关，没有任何人能代替你过。
因此，建议你下点苦功夫，把背单词的精神拿出来背诵文章。何况，并不是要求你背了之后永远牢记在心：你可以这个星期背，下个星期忘。这没有关系，相信你的大脑具有神奇的能力。背了工具箱里的文章后，你会惊讶的发现：I can think in English now！
1. Computer in Education
There is a great deal of interest in the use of computers in education. The educational use of computers is called Computer Assisted Instruction, or CAI. Many public schools in the United States have acquired computers and CAI programs to rum on them. School districts are establishing computer resource centers and special training programs to help teachers use computers. In addition, some colleges and universities are beginning to establish computer literacy requirements for graduation. In spite of all this interest in the use of computers in education, some educators and students still may be wondering if this expensive toy is really worth their time and, in some cases, money. The answer is a definite yes: The use of computers in education has important benefits for both students and teachers.
Computers enhance a student’s learning experience in many ways. First of all, the computer has the ability to accommodate individual differences in learning speed because the user (the student) is the one who controls the pace of the lessons. In addition, because a computer is nonjudgmental, the learner does not have to be afraid of reprisal or humiliation when making errors. For example, because computers can repeat information over and over, the user can ask for many repetitions of a lesson without fearing a judgmental response about his or her ability to learn. The beneficial effects of learning in a stress-free atmosphere are well documented. A third advantage of CAI is that computer can give a student immediate feedback. It can tell the student why she or he is wrong as soon as an error is made, and it can even provide an approach hint for figuring out the correct answer.
Not only do computers benefit students, they also make the teacher’s job easier. One advantage lies in the preparation of instructional materials. Schools and colleges can purchase educational computer programs that can be adapted to any learning situation. These systems, called “authoring systems,” are like skeletal lesson plans: The format of several exercises and tests is already planned out; all the teacher adds is the information he or she wants the students to learn (mathematical problems, vocabulary lists, and so forth). The authoring system automatically incorporates these teaching points into its preplanned format and then is ready to be used by several students for a long time. The system can also correct the students’ work and determine and record grades. In addition, the computer offers numerous advantages to teachers in managing their classrooms. A computer laboratory (a room having one computer for every two students) can free the teacher to meet individually with students while the rest of the class is occupied with computer lessons. Finally, computers can help teachers keep student records and chart student progress, thereby cutting down on time—consuming paperwork.”
With all of these advantages for both teachers and students, it is easy to see why there is so much interest in using computers in education. Of course, there are those who are skeptical and view computers as a passing fad. There are those also who simply are afraid of them. In time, however, computers will become as familiar in the classroom as chalkboards are today.
2. Computer Make the Workplace Less Friendly
We have seen the future, and it hurts.
That’s what millions of American office workers are discovering every year as computer come to dominate the office and the mania for ever-increasing profits consumes the work environment. If present sentiments persist, there could be a white-collar revolt, as executives and stenographers alike find that the “office of tomorrow” is just the keypunch counterpart of the sweatshop of yesterday. 感谢您阅读《ScienceandTechnolo 》一文，出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
