听力原文：When was the last time that you were able to make a long-distance call for free？
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.

The invention of telephone has greatly eased the communication among people，but callers should be careful about when to make a phone call or it will cause embarrassments.
It is not customary to telephone someone very early in the morning in the USA. If someone is called very early in the morning，while he is shaving or having breakfast，the time of the call indicates great importance of the matter which requires immediate attention of the person called. The same implication is attached to telephone calls made after 11:00 p.m. at night. If someone receives a call during sleeping hours，he assumes it’s an urgency of life or death. The time chosen for the call communicates its importance. Time plays a very important role in our social life as you can imagine. In the USA an invitation should be sent to the guests in advance because guests usually believe that they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not always necessarily true of the case all over the world. In some other countries，it may be taken stupid to make an appointment too far in advance because plans made for a date more than a week away tend to be forgotten. The concept of time varies in different regions of the world. Thus，misunderstandings are sometimes inevitable between men of different cultural backgrounds that treat time differently. Promptness is valued highly in America，for example. A lack of promptness is regarded as being impolite or not being fully responsible. In the US it would be incredible to keep a business partner or a guest waiting for an hour，and it would be too impolite and unacceptable by their social etiquettes. A person who is 5 minutes late is expected to give some words of explanation to the people waiting，though he might not complete his sentence.
