3题:The following two questions are based on the following passage:
An automaker is facing financial difficulties. The vice president of marketing has determined that the root of the company’s problems is low brand loyalty. The vice president proposes, therefore, that the company begin an aggressive advertising campaign focused on children aged from three to eight years.By securing strong brand recognition with this demographic, he argues, the company will have an advantage when these customers reach an age when they can buy cars.
Which of the following, if true, raises the most serious doubts about the vice president’s proposal
A、Studies have shown that children are an important factor in the car-buying decision for 75 percent of parents with children under 18 years of age.

B、The financial difficulties facing the company will result in the company’s declaring bankruptcy within five years if the difficulties are not addressed effectively.
C、The company’s most recent advertising campaign, focused on the theme of "Rev up your life," has received positive ratings from the demographic aged 18 to 29.
D、Children are accustomed to viewing ads for car toys while watching their favorite television programs, so ads for actual cars will appeal to them.
E、The vice president who made the proposal has only one year of experience in the automotive industry, but has spent more than 20 years in the financial services and children’s entertainment industries.

One of the best sources modem scholars have for learning about HellenisticEgypt is the large supply of papyrus fragments that have turned up in theEgyptian desert over the last century. Papyrus is a thick type of paper made from a reedy plant found inEgypt. Papyrus is much tougher than the wood-pulp paper used in modern society; whereas a book produced today will most likely fall apart within a century, there are papyrus fragments that are still legible over 2,000 years after scribes wrote on them.
It is primarily by accident that any of these fragments have surviveD、Most of the surviving fragments have been found in ancient garbage dumps that were covered over by the desert and preserved in the dry heat. The benefit of this type of archeological find is that these discarded scraps often give us a more accurate picture of the daily lives of ancientEgyptians--their business affairs, personal correspondence, and religious pleas--than the stone engravings and recorded texts that were intended to be passed down to later generations.
One of the most important papyrus discoveries of recent years was the revelation in 2001 that a scrap of papyrus that had been discarded and used to wrap a mummy contained 110 previously unknown epigrams (short, witty poems) by the Hellenistic poet Posidippus (cA、280-240B、
C、). Posidippus lived inAlexandria and benefited from the support of King Ptolemy II Philadelphos (ruled 284-246B、
C、). These new epigrams have yielded fascinating insight into the court culture and literary sensibilities of early HellenisticEgypt.
King Ptolemy, of course, was also a sponsor of the famous library ofAlexandria, the greatest depository of knowledge in the ancient worlD、According to the twelfth-centuryByzantine writer John Tzetzes, the ancient library contained nearly half a million papyrus scrolls. If that library had not burned down, maybe archeologists today would not have to spend so much of their time sorting through ancient trash!
The author’s primary intention in this passage appears to be which of the following
A、To shed light on the underappreciated work of the Hellenistic poet Posidippus
B、To compare the relative merits of papyrus, and wood-pulp paper as media for recording information

C、To discuss the ways in which papyrus fragments help scholars learn about HellenisticEgypt
D、To answer the questions regarding the burning of the library ofAlexandria, one of the great mysteries of the ancient world
E、To suggest possibly fruitful paths for future archeological research into HellenisticEgypt

Although hard statistics are difficult to come by, there is substantial anecdotal evidence that use of performance-enhancing drugs, or doping, is rampant in professional sports. Of perhaps greater significance to society are the estimated 1.5 million amateur athletes who use steroids, either to improve their appearance or to emulate the performance of their favorite professional athletes. This chemical epidemic is a pernicious threat to both the nation’s health and our collective sense of "fair play."
Nonprescription anabolic steroids have been illegal in the United States since 1991, and most professional sports leagues have banned them since the 1980s. These bans are partly a matter of fairness--a talented athlete trained to the peak of her ability simply cannot compete with an equivalent athlete using steroids--but also based on issues of health.Anabolic androgenic steroids ("anabolic" means that they build tissues; "androgenic" means that they increase masculine traits) have been linked to liver damage, kidney tumors, high blood pressure, balding, and acne. They function by increasing the body’s level of testosterone, the primary male sex hormone. In men, this dramatic increase in testosterone can lead to the shrinking of testicles, infertility, and the development of breasts; in women, it can lead to the growth of facial hair and permanent damage to the reproductive system. Steroids have also been linked to a range of psychological problems, including depression and psychotic rage.
The punishments for getting caught using steroids are severe, and the serious health consequences are well documenteD、Despite this, millions of professional and amateur athletes continue to use performance-enhancing drugs. Why is this
One clear pattern is that many athletes will do whatever it takes to get an edge on the competition. Since the 1950s, Olympic athletes have played a cat-and-mouse game with OlympicCommittee officials to get away with doping, because the drugs really do work.Athletes who dope are simply stronger and faster than their competitors who play fair. Professional athletes in football and baseball have found that steroids and human growth hormone can give them the edge to score that extra touch-down or home run, and in the modern sports market, those results can translate into millions of dollars in salary. For the millions of less talented athletes in gyms and playing fields across the country, drugs seem like the only way to approach the abilities of their heroes in professional sports.
The other clear pattern, unfortunately, is that it has been all too easy for abusers to get away with it. Steroid abuse is often regarded as a "victimless crime." One of the favored ways to trick the testers is to use "designer" steroids. There are thousands of permutations of testosterone, such as THG, that can be produced in a laB、Chemists have discovered that they can create new drugs that produce androgenic effects but do not set off the standard doping tests. Other methods have been to use the steroids but stop a few weeks before testing, to use other chemicals to mask the traces of steroids, or to switch in a "clean" sample of urine at the testing site. Other athletes use steroid precursors, such as androstene-dione, that have androgenic effects similar to those of steroids but are not illegal because they are not technically steroids. The sad fact is that unless the government and professional sports organizations are willing to get tough on the steroid problem, the use of performance-enhancing dugs in sports is not going to enD、
