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.

Just as Roman gladiators drank the blood of foes to gain strength, modem Olympians have infused the blood of their own to gain endurance. Blood doping, which tainted the triumphs of some Olympians, has at last been banned.
Blood doping, in short, means withdrawal of one unit of a little more of blood from an athlete's system about four to six weeks before a competition. The blood is then stored in a frozen state while the body replenished the lost blood through natural processes. The extracted blood is unfrozen and then pumped back into the athlete's system just before the competition. This increases the body's hemoglobin count, hereby increasing the capacity for oxygen delivery and raising the level of endurance.
A recent colloquium on the ethics of blood doping, summarized in The Physician and Sports Medicine, cited eases of runners getting blood transfusions so they could run fast enough to qualify for Boston Marathon and of blood doping in dog and horse racing.
Blood doping may be surprisingly common among world-class endurance athletes, especially cyclists and runners. Blood doping is cheating and it is now banned by the International Olympic Committee, but it is still impossible to test, and till sure checks are found, one can only count on the personal ethics of the sportspersons concerned.
Does blood doping really work？ Buick et al. and Williams et al. have made some studies in the laboratory. In one study, 11 highly trained male track athletes underwent extensive treadmill testing before and alter phlebotomy with re-infusion of 900mi of antilogous freeze-preserved red cells. The blood doping increased the mean hemoglobin concentration 8% (from 15.1% to 16.3% gnm/100ml) , maximal oxygen consumption 5% , and running time to exhaustion 35%. In another study, 12 experienced male distance runners who received 920ml of antilogous blood had a mean 7% increase in hemoglobin concentration and a mean 45-second improvement in time on a 5-mile treadmill run, compared with results after they received 920m1 saline. In the third study, 9 male college students who received two units antilogous blood had a significant increase in hemoglobin concentration and maximal oxygen consumption on a cycle ergo-meter.
It is reasonable to conclude that blood doping does work when properly performed in the laboratory. But does it work in the field？
The problem in determining if blood doping works in the field is that almost all the reports are anecdotal. Whether it works or not, blood doping as it was done for the U.S. Olympic cyclists is to be condemned. Three of the cyclists developed flu-like symptoms 36 hours after transfusion, and one of them, when asked about blood doping, said, "Yeah, I did it. I got sick and it ruined me for the Olympics." To be sure, some of the cyclists who blood-doped won medals, but so did some who refused blood doping. Likewise, not all Olympians who admitted to blood doping were medal winners: an Italian runner who blood-doped for the marathon said he ran poorly and the national cross-country team alleged to have blood-doped ran poorly. In short, one cannot tell from anecdotal reports whether or not blood doping works in the field.
Which of the following statements best expresses the main idea of the passage？
A．Blood doping does afford athletes a competitive advantage though it is not quite safe.
B．Blood doping works in the laboratory, but there is no evidence to show it works in the field.
C．Blood doping is becoming increasingly common in the world of sports.
D．Athletes who Blood-dope for endurance can perform. better than others.

However important we may regard school life to be, there is no gain saying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of tile school personnel or they can consciously or unconsciously hinder and thwart curricular objectives.
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript. writing and developmental mathematics.
Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils' progress, can significantly aid in achieving a harmonious interplay between school and home.
To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.
Too often, however, teachers' conferences with parents are devoted to petty accounts of children's misdemeanors, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home.
What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents' minds for the best utilization of the many hours that the child spends out of the classroom.
The central idea conveyed in the above passage is that______.
A．home training is more important than school training because a child spends so many hours with his parents
B．teachers can and should help parents to understand and further the objectives of the school
C．parents unwittingly have hindered and thwarted curricular objectives
D．parents have a responsibility to help students in doing homework
