摘要: Which do you believe to be true? A. Nokia is a very popular foreign phone seller B. China produced and sold most of the mobile phones to other countries C. Mobile communications account for the most part of the total long-distance communications D. China has had quite advanced core technologies Wind is the great maker of waves. There are exceptions, such as the tidal waves sometimes produced by earthquakes under the sea . But the waves most of us know are produced by winds blowing over the sea. Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough to crest . It has length -- the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same --- for all depend upon the wind, upon the depth of the water and many other matters. The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so. For if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way: Speed = wavelength × frequency Here, wavelength is the distance between two high points , frequency means the number of cycles per second.

        China Mobile, the country’s largest mobile communications operator, has accounted for nearly 40 percent of revenues (税收) in the domestic(国内) telecoms market. That puts it at the top of the six major telecoms operators in the nation, according to the latest official statistics(统计).

The other five are: China Telecom, 31.1 percent; China Netcom, 16.6 percent; and China Unicom, 13.4 percent; China Satellite Communications Corp and China Rilcom, 1.5 percent.

Mobile communications and the IP phone business have gradually replaced traditional long-distance calls. Mobile communications account for 28.5 percent of the total long-distance communications business. IP phones have 41.4 percent, while traditional long-distance calls are down to 30.1 percent.

In another ranking(排行表), Nokia, Motorola, Bird, TCL and Siemens came in as the top five mobile phone sellers in China in the first half of this year, according to South Daily. They report also says that during this period, China produced 82 million handsets (including GSM, GPRS and CDMA phones) and sold 80 million. Of the phones sold, 37 million were exported to other countries.

Analysts point out that China’s lack of key technologies and its heavy dependence on overseas technologies have proved to be an obstacle (障碍)for development of home-made phone makers.

 

56.   From the passage, which is NOT true?

       A. China Mobile is China’s largest mobile phone sellers.

       B. China Mobile is China’s largest mobile communications operator.

       C. China Mobile has covered nearly two fifths of the income in the telecoms market in China.

       D. China Mobile has taken the first place in the telecoms market.

57.  Mobile communications have gradually taken the place of      .

       A. IP phone service             B. traditional long-distance calls

       C. traditional telephones       D. telecom operators

58.  Which do you believe to be true?

       A. Mobile communications account for the most part of the total long-distance communications.

       B. China produced and sold most of the mobile phones to other countries.

       C. Nokia is a very popular foreign phone seller.
