答案 It has been widely noted that, with the growing use of computers and calculators both in the classroom and in the home, the level of literacy and mathematical ability of students is dropping. This raises serious doubts about the value of the progress of science and technology. Advances in science and technology have certainly brought about many benefits for mankind. They have made our lives more comfortable and healthier. In addition, they have eased the burden of work for most people and provided them with more leisure opportunities, while at the same time increasing productivity dramatically. Nevertheless, it cannot be denied that technology has some negative side-effects. As mentioned above, with computers which check spelling, grammar and calculation, students have little incentive to learn how to do these tasks for themselves. Another aspect of this issue is that the effect of technol0gy depends on how we use it. For instance, explosives may be used to make road construction easier, or it may be used to kill people. Nuclear reactors can supply huge amounts of cheap electricity, but if carelessly handled they can cause devastating pollution. We can conclude that the progress of science and technology has both positive and negative effects. We must make sure that the positive ones are encouraged and the negative ones are eliminated. Among other things, this means that students are warned not to let computers and calculators do all the work for them.
