Some people suggest for better roads, others for cars to be banned (禁止) from city centers and yet others say better public transport would attract drivers from their lonely and boring journeys. But the important question is what natural power creates a big city center. We are, after all, in an age of electronic communication; our big shopping areas have moved out of city centers, and our living areas moved out of them long ago. Yet some force causes offices and service industries related to them to gather in London or New York or Tokyo. This suggests that far from the problems of a crowded environment forcing companies and people to move out, there is a critical (重大的) size beyond which more companies are attracted to move in. Nobody seems to know why, yet the answer is important to the way traffic jam is dealt with. Which of the following is NOT mentioned in the passage as the cause of the traffic problem？ A．The poor public transport. B．The over-concentration of shopping centers. C．The great number of cars in the city centers. D．The bad road conditions.

A．be very helpful B．be hostile C．add to their children"s difficulties D．spoil children

Matt Flanigan, President, TIA: Well, today I would say speed and bandwidth. Especially, a little smile up to the consumer' is probably a big issue holding back the Internet. But security is also important with electronic commerce. And until they really solve that, people are not gonna feel secure. Host: All right. Well, Let's introduce our guest. We're joined by an executive from Effnet: Tomas Althen. Welcome to the program. We're delighted to have you. Tomas, let's start with this. What sort of Internet issue is Effnet dealing with？ What kind of solutions do you bring to the table？ Tomas Althen, CEO, Effnet Group: The Internet is growing at a very rapid speed at the moment. As you must know, the number of users doubles every year. However, also the information on the net doubles every month. And this calls up the two issues we have been hearing about here, speed and security. Host: Well, let's look at more details. Look at this video about the city council of Stockholm, Sweden. Narrator on the video: Here is the power. The politicians and high civil servants at Stockholm County Council are used to having access to qualified information. Now with everyone using Internet and Intranet, some information has to remain secret. The decision on how to do this are mad here at IT Control. They have found the way to let 10, 000 employees use the Internet but some information can still be accessed only by qualified people. This is the firewall keeping the information system secure. A box in the basement with software from Effnet. Scandinavia is known for its technology. Cellular phones and Internet are part of daily life. And here in Sweden there are some young, very innovative up-starting companies. One is Effnet, founded in 1997 and already on the world market. As the world demands speed and security and reliability, Effnet's gigabit router on a card makes security easier. The generic plug-in card, firewaller and router in one, proves that they are ready to meet the world demand. Host: Well, how does the firewall work？ We were told a few days ago that one of the new methods of transmission was to break everything up into little packets, send them all into the Internet and hope they arrive in the same order, and so on. Is the protection of these packets from being raided is this the principle task of the firewall？ Tomas Althen: You can say that in one sense. You also don't want packets to come in to your data system, or into your network, packets which you don't want to be there. You want to be able to decide for yourself as an organization or as a company: hey, I don't want these guys to be able to access my treasure. And to do that you need to do some filtering. You need to decide which packets are allowed, which packets are not allowed. You have to do that very fast so you don't end up with yet another bottleneck. And we solved that problem. Host: Let's look ahead a couple of years and have you estimate for us how you see this technology evolving. What do you think will be different or new on the horizon in a couple of years？ Tomas？ Tomas Althen: More and more has been put into smaller and smaller spaces. We are making quite a leap in putting all these features on one card. But the next step is clearly putting them on one chip. And we are talking to chip vendors to try to do that as quickly as reasonable. They usually say that one year in this business is seven ordinary years. So, that would be 14 years from now. We'll see things more and more integrated. For Effnet, in two years I would s A．The quality of being easy to use. B．For most of us, broadband access is years in the future. C．To maximize the Internet's sufficiency.

Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug. J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch. Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain. By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too. Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense." The passage most possibly comes from______. A．a medical textbook B．a psychology textbook C．a popular magazine D．a serious magazine
