【正确答案】Nowadays, computers play an important role in our society. They dramatically change the way we work, study, and shop. But while the computer industry is offering us benefits never dreamed of before, it also creates some serious problems. For example, there has been a growing concern over unethical behavior in electronic communication. Piracy, hacking, and virus sabotage are running wild. Should these behaviors be regarded as crimes? How can we stop these actions? Another concern is about overreliance on the computer. Computers are not as reliable as people think, information on the Internet may be false. Worse still, depending too much on computers may undercut our ability to think critically and set up barriers between people.
