移动电话正在成为2l世纪一个主要的技术领域。在几年之内，移动电话将会发展成为多功能的通信工具，除了语音之外，还可以传输和接收视频信号、静止图像、数据和文本。个人通信的新纪元即将到来。
在一定程度上多亏了无线网络的发展，电话正在与个人电脑和电视融合起来。不久之后，配有高分辨率显示屏的轻巧手机便可以与卫星连接。人们可以随时随地通话，收发电子邮件或者参加视像电话会议。这种手机也许还会吸收电脑的许多主要功能。移动通信工具有望带来一些互联网所能提供的新服务，如股票交易、购物及预订戏票和飞机票。
电信革命已在全球范围内展开。不久之后，用一台装置就可以收到几乎任何形式的电子通信信号。最有可能的是一部三合一手机。在家里它可以用作无绳电话，在路上用作移动电话，在办公室里用作内部通话装置。有些专家甚至认为移动视像电话将超过电视，成为主要的视频信息来源.

SECTION 1 Compulsory Translation (30 points)
Japan owes a lot to China. Chinese demand for Japanese goods has helped Japan's economy recover, while competition has pressured executives to start restructuring Japan's companies and banks.
Japan is an example of how China is offering two benefits to the global economy. One is the way in which China is acting as an economic engine, buying up ever-increasing amounts of goods and natural resources. The other is the flow of inexpensive Chinese goods that drag down consumer prices across the world.
There are downsides, like the decline of manufacturing industries from Detroit and Perth. Folks in developed economies losing jobs or taking pay cuts would hardly agree that China's rising influence is a good thing.
But at the moment, China's 9.5 percent growth rate is proving more of a blessing than a bane for countries like Japan.
Quietly, at the start of this decade, Japanese companies began shifting production abroad, cutting costs, selling off extraneous businesses and paying down debt. 'The government also stepped up efforts to attract more foreign direct investment, something Japan had little use for in the past.
Taken together, these actions largely prompted by China's advance, have led to the most organic and convincing recovery Japan has seen in years. While Japan has much further to got to make its economy more globally competitive, it is worth noting how far it has come from the dark days of the late 1990s.
There are many benefits inherent in China's advance. One of them was spelled out by Anatole Kaletsky, an editor and economic columnist at The Times of London. He wrote on August 18 that China's rise is making the richest nations even richer.
Along with pushing down global prices of mass-produced goods, China's influence may actually be pushing up the prices of products and services China does not or cannot make. That can be seen in the prices of things that China consumes — oil, financial services, luxury goods and real estate.
Kaletsky said that as prices of luxury goods and financial services are driven higher, prosperous countries with service industries become wealthier, compared with manufacturing countries.
