听力原文：Donating blood plasma has always been a noble pursuit to help those in need. Since last September, there has been an upsurge in blood donations, as the need has become more emphasized and more empathized. But if you've had a tattoo or piercing within the last year, you will more than likely be turned away from any blood bank.
When you go to a blood bank to give plasma, they ask you a series of questions to determine if you are eligible to donate. Obviously, they don't want to risk accepting contaminated blood, so they will ask about your sexual history, current health status and other related questions, including whether or not you have gotten a tattoo or piercing within the last 12 months.
All blood that is donated is screened for disease such as HIV, Hepatitis, Syphilis and other common blood- born ailments.
However, it goes without saying that it is a waste of the blood bank's and the donor's time to harvest blood that is tainted and thus worthless.
So, in order to avoid wasted time, they ask these questions to screen the potential donor. And although even I would be quick to say that tattooing and piercing are much safer than some medical professionals like to indicate, there is still always a chance of getting and carrying a disease unknowingly from a tattoo or piercing, especially Hepatitis. That has been the object of many heated arguments and stringent regulations.
If you should happen to contract a disease from a tattoo or piercing, it should show up in a screening after 12 months, which is the reason for the waiting period. Yes, maybe it's a little over-precautious, but would you want to be the one on the receiving end of dirty blood？ If there, is even a chance, it is better to be safe than sorry.

A patent is an exclusive right given to an inventor for his or her invention. In other words, a patent is a monopoly right given to the inventor for the invention. A patent confers on the inventor the right to price and to sell the invention in any way he or she desires, in the United States, patents are granted by the Patent Office for 17 years. Although economists generally condemn monopoly as a form. of market organization since monopoly imposes costs on the economy, patents present a more subtle case for monopoly theory. Specifically, can patent monopolies be justified？
In general, economists complain about the costs of monopoly because they believe that the same industry could be organized competitively. A patent monopoly grant for 17 years presents a different problem. That is, the purpose of the patent system is to encourage invention. The issue is not monopoly versus competition but, more fundamentally, invention versus no invention. Is the world better off with the invention, even though it is monopolized for 17 years？ In other words, what are the costs and benefits of a patent？
Consider the simple case of a new consumer product with a positive demand, such as a camera utilizing a new exposure process. The costs of the patent monopoly are simply the deadweight costs of monopoly measured by the lost consumers' surplus from the 17-year patent monopoly. This cost must be assessed carefully in the context of an invention, however. What are the benefits of the patent system？ First, there is the increase in consumer well-being brought about immediately by a desirable invention. In 17 years, the patent monopoly ends, and a second source of benefits arises: The price of cameras will fall to a competitive level, and consumers will reap the benefits of the camera at a lower price. In sum, theory of monopoly helps us to assess the costs and benefits of the patent. One can quibble about patent monopolies, arguing, for example, that they are granted for too long a time.
In the end, the patent system creates goods and services and technologies that did not previously exist. In this respect it is a valuable System for the economy. The patent system also underscores the importance of property rights to ideas as a source of economic growth and progress.
The first paragraph mainly______.
A．focuses on business monopoly
B．tells us about the patent system in America
C．discusses a special form. of market organization
D．defines what a patent is and its function

According to reports in major news outlets, a study published last week included a startling discovery: the nation's Jewish population is in shrinking. The study, the National Jewish Population Survey, found 5.2 million Jews living in the United States in 2000, a drop of 5 percent, or 300,000 people, since a similar study in 1990. What's truly startling is that the reported decline is not tree. Worse still, the sponsor of the $6 million study, United Jewish Communities, knows it.
Both it and the authors have openly admitted their doubts. They have acknowledged in interviews that the population totals for 2000 and 1990 were reached by different methods and are not directly comparable. The survey itself also cautions readers, in a dauntingly technical appendix, that judgment calls by the researchers may have led to an undercount. When the research director and project director were asked whether the data should be construed to indicate a declining Jewish population, they flatly answered no. In addition, other survey researchers interviewed pointed to other studies with population estimates as high as 6.7 million.
Despite all this, the two figures --5.2 million now, 5.5 million then --are listed by side in the survey, leaving the impression that the population has shrunk. The result, predictably, has been a rash of headlines trumpeting the illusionary decline, in turn touching off jeremiads by rabbis and moralists condemning the religious laxity behind it. Whether out of ideology, ego, incompetence or a combination of all three, the respected charity has invented a crisis.
United Jewish Communities is the coordinating body for a national network of Jewish philanthropies with combined budgets of $2 billion. Its population surveys carry huge weight in shaping community policy. This is not the first time the survey has set off a false alarm. The last one, conducted by a predecessor organization, found that 52 percent of American Jews who married between 1985 and 1990 did so outside the faith. That number was a fabrication produced by including marriages in which neither party was Jewish by anyone's definition, including the researchers.
Its publication created a huge stir, inspiring anguished sermons, books and conferences. It put liberals on the defensive, emboldened conservatives who reject full integration into society and alienated ordinary folks by the increasingly xenophobic tone of Jewish communal culture. The new survey, to its credit, retracts that figure and offers the latest survey has spawned a panic created by the last one.
So why did the organization flawed figures once again？ Some scholars who have studied the. survey believe the motivation then came partly out of a desire to shock straying Jews into greater observance. It' s too early to tell if that' s the case this time around. What is clear is the researchers did their job with little regard to how their data could be misconstrued. They used statistical models and question formats that, while internally sound, made the new survey incompatible with the previous one. For example, this time the researchers divided the population of 5.2 million into two groups--"highly involved" Jews and "people of Jewish background"- and posed most questions only to the first group. As a result, most findings about belief and observance refer only to a subgroup of American Jews, making comparisons to the past impossible.
We can' t afford to wait a decade before these figures are revised. The false population decline must be corrected before it further sours communal discourse. The United Jewish Communities owes it to itself and its public to step forward and state plainly what it knows to be true: American Jews are not disappearing.
According to the passage, which of the following statements is NOT true about the National Jewish Population Survey？
A．It found a decline of 300,000 Jews in ten years.
B．It was carded out by United Jewish Communities.
C．This is the first time United Jewish Communities has made mistakes in the population survey.
D．The reported decline is not reliable.

The best indication of whether a man or woman is capable of genuine friendship with a mate, social psychologists say, is whether he or she has close, nonsexual friends of the opposite sex. Also important, says Pittman, is whether that person is friends with his parents, since someone still at war with his parents is probably not ready for friendship with a romantic partner.

The idea that "parents don't matter"— shorthand for the view that how parents treat their children has no effect on the kids' behavior, values, achievements and other outcomes—just won't go away. I can【62】believe it's been more than 10 years since I wrote about the【63】claim that only genes and peers【64】children; once parents contribute an egg or sperm, they have no effect on how their kids【65】
So I was【66】by what's being called "the largest meta-analysis ever conducted on the association between parenting styles and delinquency (犯罪，尤指青少年). " The meta. analysis, in the Journal of Abnormal Child Psychology, looked at 161 published and unpublished studies【67】the question, and found that how well parents【68】their children, whether they expressed rejection or hostility, and a number of other【69】indeed had an effect.
What's particularly interesting is the【70】of the effect. An association can be statistically significant without being【71】significant; that is, there can be true cause-and-effect, but a tiny effect. Not so in this case.【72】kids for good behavior. had an effect size of 11%, for instance; not huge, but not tiny (it means that 11% of the difference between kids' levels of delinquency is due to whether their parents rewarded them for good behavior, something that reduces delinquency). Being authoritative also【73】delinquency, again with an effect size of 11%,【74】being authoritarian (独裁) increased delinquency, with an effect size of 12%. Put the two together and being authoritarian as opposed to authoritative【75】for a swing of 23%. Physical【76】and verbal aggression also were associated with more delinquency.
The "parents don't matter" school might【77】that little delinquents-to-be bring out the worst in parents, who turn authoritarian. It is the kids'【78】tendencies that cause later delinquency, according to this argument, not how parents【79】. The【80】with this claim is the many studies showing that whether you are an authoritarian or an authoritative parent "is most often determined before your first kid is even born, and is highly【81】upon your own experience of discipline.., and your general political/personality orientation," as clinical psychologist Nestor Lopez-Duran wrote.

One day two scientists were quarrelling about whose watch was better, the German one or the Japanese one. Since they were scientists, they decided to do an experiment to test the watches. They went into their lab and filled a basin with water, put the watches in, waited for 20 minutes and took them out.
They could see there was something wrong with both watches. They observed them for several hours before speaking to each other. They both silently found the German watch was losing 60 minutes and the Japanese are doubled that.
