听力原文:Hast: Today, we're going to examine some of the complexities involved in managing today's Internet. And our industrial expert here for us today is Matthew Flanigan, President of the Telecommunications Industry Association. Matt, many thanks. Welcome to the program. What are some of the key issues that we're still grapping with when trying to maximize the Internet's sufficiency?
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.

In what now seems like the prehistoric times of computer history, the earth's postwar era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction.
Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.
Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer may provide; it should not be seen as a substitute for fundamental thinking and reasoning skills.
What is the main purpose of this passage?
A.To look back to the early days of this passage.
B.To explain what technical problems may occur with computers.
C.To discourage unnecessary investment in computers.
D.To warn against a mentally lazy attitude towards computers.

Aristotle, the Greek philosopher, summed up the four chief qualities of money 2,000 years ago. It must be lasting and easy to recognize, to divide, and to carry about. When we think of money today, we picture it either as round, flat pieces of metal which we call coins, or as printed paper notes. But there are still parts of the world today where coins and notes are of no use .A traveler there might starve if he had none of the particular ‘ local money ’.
Among isolated peoples ,who are not often reached by traders from outside ,commerce usually means barter ,which is a direct exchange of goods .Perhaps it is fish for vegetables or meat for baskets .For this kind of simple trading, money is not needed ,but there is often something that everyone wants ,such as salt to flavor food, shells for necklaces ,or iron and copper to make into tools. These things — salt ,shells or metals — are still used as money in out-of-the-way parts of the world today.
Salt may seem rather a strange material to use as money ,but in countries where the food of the people is mainly vegetables ,it is often an absolute necessity .Cakes of salt ,stamped to show their value ,were used as money in Tibet until recent times, and they can still buy goods in parts of Africa.
Cowrie seashells have been used as money at some time or another over the greater part of the Old World. These were collected mainly from the beaches of the Maldive Islands in the Indian Ocean ,and were traded to India and China. In Africa ,cowries were traded right across the continent from East to West .Four or five thousand went for one Maria Theresa dollar ,an Australian silver coin which was once accepted as currency (货币) in many parts of Africa.
Metal was used as money in many parts of the world .Iron ,in lumps ,bars or rings is still used in many countries instead of money .It can either be exchanged for goods ,or made into tools or weapons. The early money of China ,apart from shells ,was of bronze ,often in flat ,round pieces with a hole in the middle ,called ‘ cash ’.The earliest of these are between three thousand and four thousand years old — older than the earliest coins of the eastern Mediterranean.
Nowadays ,coins and notes have supplanted nearly all the more picturesque forms of money ,and although in one or two of the more remote countries people still store it for future use ,primitive money will soon be found only in museums.

A.pieces of metal or metallic paper

A.even if his money was of the local kind
B.even if he had no coins or notes

D.even if he had plenty of ready money
3.What can we infer from the passage?
A.Isolated peoples exchange goods by means of barter.
B.Salt cakes are taking the place of picturesque forms.
C.Seashells could be traded with Maria Theresa dollars.
D.The Chinese were among the earliest users of metal ‘ cash ’.
