You can use your Business Tele-card (电话卡) International at any card phone in the United Kingdom. Here is some information about making international phone calls.

You can now phone almost any country in the world, although in some cases you can only call big cities. When you can’t make direct dialing calls, you can ask the international operator to help you. This is more expensive and takes more time, but it may be helpful if you want to speak to a particular person and no one else in this case you should ask for a “person-to-person” call. Even more expensive is a reverse (反向的) charge call where the person who receives the call pays.

If the international line is busy, you can reserve (回机) a call, explain the number you want and the operator will call you back when the line is free.

You can save money by calling outside office hours, for example, early in the morning, late at night, and on Sundays.

Remember that the time may be different in the country you are calling. International time is based on GMT(Greenwich Mean Time).London is on GMT and Moscow, for example, is 3 hours ahead.

There is one problem: change to DST(Daylight Saving Time)for the summer. In the UK, clocks are put forward one hour in the spring and put back in the autumn, and so London is one hour ahead of GMT in the summer.

　　Larry King: I'm having this conversation with you on a computer, and I'm wondering if e-mail is going to replace the post office in the future.

　　Bill Gates: E-mail won't replace the post office, but it will replace a lot of paper the post office carry around today.

　　King: Tell me how a computer will be used in the average home thirty years from now.

　　Gates: You'll have lots of thin flat screens covering the walls of your house and you'll carry a hand-held device（装置）around with you. The screens will feed whatever visual information you want--live video from a place in the world you like, an art reproduction（复制品）.

　　King: What happens when the power goes out?

　　Gates: We're very dependent today on electricity and we still will be in years. If there's a power failure, you won't get much work done, although battery technology will improve enough that short power failures won't necessarily shut down all of your computers.

　　King: Are we going to get television and news and entertainment from the Internet rather than from cable TV in the house?

　　Gates: News and entertainment will be delivered from the Internet to cable television and telephone connection in our homes. We'll access（存取）this information using a variety of devices, some of which will be like today's televisions.

　　King: Will a person be able to work in the future without having any computer skills?

　　Gates: There will still be jobs for people without computer skills, but a smaller percentage than exist today. The amount of the workforce that lacks computer skills will decrease as people not having those skills get retrained or retire. Most young people have computer skills or at least an enthusiasm（热心）to get them.

　　King: Describe an office in the future. Tele-phone? Fax machine? Conference room? Will there be an office building?

　　Gates: The key element of the office of the future is that it will have lots of flat screens, just like your house will. And these screens are going to be everywhere once they get thin enough, cheap enough, and high enough in quality. You'll carry around a lightweight screen the way you carry a wallet or cell phone or newspaper today.
