听力原文： When was the last time that you were able to make a long-distance call for free？ If you said "never", you probably have not been introduced to VOIP or Voice Over Internet Protocol. But, is this new technology as efficient as its counterpart, analog telephone service？ Since the demand for world-wide communication has grown, the internet has become the most popular way of communicating. Although Communication via e-mail seemed to be the cheapest way to do business with those overseas, it wasn't always the most effective. Verbal communication is the best way to build strong relationships and eventually," close the deal". When compared to analog phone service, VOIP is cheaper and has the same quality of service. Since VOIP uses a single network to transfer voice and data, the overall cost per call is cheaper to the service prodder than using two separate networks. When voice and data are transferred together on a single network, the service providers only need to build and maintain one network, thus hire less staff. These companies have also learned to manage both voice traffic and data applications correctly to reduce any sacrifice in quality. Although there is a monthly charge for the service, VOIP phones cost about the same as a regular business phone. With all of its benefits, VOIP should take the place of analog telephone service within a few years. What does VOIP refer to？ A．An Internet forum. B．A technology of telephone service. C．Communication via e-mail. D．An Internet conference.

Today the car is the most popular sort of transportation in all of the United States. It has completely replaced the horse as a means of everyday transportation. Americans use their car for nearly 90 percent of all personal trips. Most Americans are able to buy cars. The average price of a recently made car was $ 2050 in 1950, $ 2740 in 1960 and up to $ 4750 in 1975. During this period American car manufacturers set about improving their products and work efficiency. As a result, the yearly income of the average family increased from 1950 to 1975 faster than the price of cars. For this reason purchasing a new car takes a smaller part of a family's total earnings today. What was the only use of trains before the 20th century？ A．The use for short-distance transportation.
