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.

A meager diet may give you health and long life, but it's not much fun—and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.
Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes.
"This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C..
No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says.
If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.
But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'."
Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.

If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4, 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa because they had not learned to write.
Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call ？remembered history ” . Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But if there are no written records, such spoken stories are often very helpful.
Which of the following is NOT suggested in the passage？
A.Written history is more reliable.
B.Written records play an important role in learning about history.
C.A written account of our daily activities helps to answer many questions.
D.Where there are no written records, there is no history.
Little is known about the central Africa 200 years ago because ______.A.there was nothing worth writing down at that time
B.people there ignored the importance of keeping a record
C.people there did not know how to write
D.the written records were perhaps destroyed by a fire
“ Remembered history” refers to ______.A.history based on a person’s imagination
B.stories of important happenings passed down from mouth to mouth
C.songs and dances about the most important events.
D.both B and C
“ Remembered history” is regarded as valuable only when ______.A.it is written down
B.No written account is available
C.it proves to be timely
D.People are interested in it
It is suggested that we could have learned more about our past if ancient people had ______.A.kept a written record of every past event
B.burnt their written records in wars
C.told exact stories of the most important happenings
D.made more songs and dances

Feelings of love may wax and wane during a relationship, but trust is constant. Infidelity is the most devastating betrayal of trust a couple can experience. That survey found that when one partner had sex outside the relationship, the couple were more likely to break up. Even a little bit of infidelity can set forces in motion that eventually wrech a marriage. Only when we trust our lover to be faithful and know that he or she can trust us do we fell comfortable and at peace with our own conduct and our relationship.
