In China phone talk is expensive. If you want to make it cheaper, make phone calls using t

he Internet, which can cost as little as 30% or even 5% of a traditional call.

But changing your DDD(domestic direct dial) and your IDD(international direct dial) calls for the net version, called voice over the internet protocol(互联网协议) or VOIP, requires you to choose between different types of technology, with different advantages.

If a telephone connection was a road, a regular phone call allows you and the person you are calling to share the road without anyone else. On this empty road, the connection is fast, efficient, and uninterrupted. But with VOIP technology, your voice is broken into millions of separated packets of information that share the road with all the billions of other bits of information on the Internet. When the packets reach the person you are calling, they are gathered to resemble your voice. Depending on which type of VOIP you are using, the speed of the Internet connection, Internet traffic, and the service provider, the resulting voice quality can vary—from quite good to quite awful.

The three main ways of using the internet to make calls are PC-to-PC(家用电脑) calls, PC-to-Phone calls and China's popular IP phone card.

VOIP calls are cheapest when they are made between two computers or between a PC and a telephone. For both, make sure you have a computer, an internet connection, a sound card, and most importantly, a headset(套头耳机) with a microphone.

People prefer IP phone calls to ordinary ones because the former is ______.

A．much more convenient

B．much cheaper

C．more dependable

D．more efficient

China Calls for Unified International Rules Against Internet Crime

Cyber security has always been a serious issue as the Internet industry is ever growing. Nowadays, people can easily connect to the Internet with a simple click of a mouse. But the global network can be easily destroyed by a single leak. The world is facing a difficult situation in keeping web security.

Currently, there are no unified international rules for maintaining Internet security. China has called for unified international rules against Internet crime. Last year China and some other countries handed in a draft Code of Conduct on Information Security to the UN.

World leaders and experts discussed the possible Internet threats facing the world. They agreed that the only way to deal with Internet security threats was to trust each other and strengthen cooperation. The threats cannot be solved by any one country alone. And for these reasons, countries would have a greater chance of trusting each other in dealing with such threats.

Though great efforts were made to issue common regulations for the Internet, few results have been achieved yet. There's still a long way to go for unified global Internet security rules and regulations.

26. Maintaining web security is () for the world.

A. easy

B. a piece of cake

C. difficult

27. There are () to maintain cyberspace security.

A. no unified international regulations

第9题

There is more to school education than instruction and passing knowledge. To live up to hi

s or her image, a teacher at an elementary or secondary school has to have positive influence on the pupils in terms of manners, attitudes and views of life. There is reason to claim that a teacher is a parent, consultant and role model all rolled into one. When a teacher has become someone to talk to, turn to and correspond to, his role as a friend is highlighted. Accompanied by teachers who are considerate, helpful and responsible, a child is likely to be impressed by such good qualities and eventually does the same to others. However, it is no easy job to be a successful teacher. Effective lecturing calls for experience, the sense of humor, devotion and an intimate knowledge of the subject. In China, admission to college is highly competitive, making it necessary for parents to enable their children to study under the best possible teachers to increase the chance of being admitted by well-known institutions of higher learning.
