A Ask Dr Jeffers. This month Dr. Jeffers is answering questions about the human brain and how it works. Dear Dr. Jeffers, One of my colleagues, Felix Moeller, told me
that scientists are learning to use computer to “read minds”. Is there any truth to this story? Jane Leon, New York, USA Dear Ms. Leon, Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects （受试者） were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting （减） the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions（假设）70 percent of the time. It’s not quite mind reading, but it’s certainly a first step. —Dr. J. Dear Dr.Jeffers, My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢) him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not? —Glenn Lewis, Vancouver, Canada Dear Mr. Lewis, It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction. —Dr. J. 46. What can we learn from the answer to the first question? A. Some equipment is able to read human minds. B. Some progress has been made in mind reading. C. Test subjects have been used to make decisions. D. Computer programs can copy brain processes. 47. People laugh when tickled by others because the feeling is ________. A. unexpected A. Ms. Leon B. expected B. Mr. Lewis C. comfortable C. Mr. Moeller B. a test subject D. a medical doctor D. uncomfortable D. Dr. Jeffers 48. Who has got a little child according to the text? 49. According to the text, Jeffers is probably ________. A. a computer programmer C. a human brain expert

And I don’t think their life was better or worse, there were lots of things back then that I’m happy I don’t have to deal with nowadays, but on the other hand life was simpler. “We had a lot more time with our family, and it was hard being nice to each other all the time, ” eleven-year-old Hilary said. So what did the Bowler family miss most about modern life while living in the 1900 house? Paul, 39: “telephone and a hot shower” Joyce, 44: “a quick cup of tea from a kettle you could just turn on” Hilary, 11: “rock CD” Joseph, 9: “hamburger and computer games” 54.

To chat on the Internet D Stop Spam When I first got an e-mail account ten years ago, I received communications only from family, friends, and colleagues. Now it seems that every time I check my e-mail, I have an endless series of advertisements and other correspondence that do not interest me at all. If we want e-mail to continue to be useful, we need specific laws that make spamming(发送垃圾邮件) a crime. If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to send hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products, individual (个人的) e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time? This problem is troubling for individuals and companies as well. Many spam e-mails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their
networks. These computer problems raise production costs of companies, which are, in the end, passes on to the consumer. For these reasons, I believe that lawmakers need to legislate (立法) against spam. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience. 57. What does the underlined word “correspondence” in the Paragraph 1 probably mean? A. messages B. ideas C. connections D. programs 58. According to the text, what is the major cause of the flooding spam? A. Companies rely on e-mail for communications. B. More people in the world communicate by e-mail. C. Many computer viruses contain spam e-mail. D. More advertisers begin to promote sales through spam. 59. According to Paragraph 3, who is the final victim of spam? A. The business A. To inform B. The advertiser B. To educate C. The employee C. To persuade D. The consumer D. To instruct 60. What is the purpose of the text?
