题目内容
Range
At present,there are five network firms---China Telecom,China Unicom,Jitong Communications,China Netcom and China Mobile---that are allowed to operate IP services in China.Each company has its advantages in service.
Charge
As the Ministry of Information Industry co-ordinates,the charges of IP calls of the five companies are the same,0.30 yuan per minute for DDD calls.4.80 yuan per minute for IDD calls,2.50 yuan for calls from the mainland to Hong Kong,Macao,and Taiwan,and 1.50 yuan from Shenzhen to HK,Zhongshan and Zhuhai to Macao.IP callers don’t enjoy discounts on holidays.
China Telecom has the widest coverage.All cities in China with telephone access and most countries in the world are open to China Telecom’s IP card.
China Unicom’s IP card can reach 29 cities nationwide and more than 130 countries and regions worldwide.Jitong IP can access(接通)12 cities in China and over 70 countries and regions worldwide.
China Netcom’s IP card can reach 14 cities in China and 149 countries and regions in the world.
China Mobile’s IP card is open to only six cities nationwide but can access more than 200 countries and regions worldwide.
Voice quality
China Telecom realizes its IP service by the public Intermet,therefore net congestion(拥挤)and voice delay may sometimes disturb conversations.The other four companies have their private data networks,which help to increase transmission speeds and improve voice quality.
Other services
China Telecom,Jitong and China Mobile offer account transfer services.Users can transfer the remaining sum of money on one card to another card.
Jitong and Netcom Link their services with bank cards.One can enjoy IP’s service without an IP card.Bank card users can make IP phone calls with their bank card numbers,so they needn’t buy new IP cards and remember the new numbers again and again.
As for customer service,China Telecom,China Unicom and China Mobile provide free hot line service,while Jitong and Netcom charge for their services.

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.
