It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom— or at least confirm that he's the kid's dad. All he needs to do is shell out $30 for paternity testing kit (PTK) at his local drugstore—and another $120 to get the results.
More than 60,000 people have purchased the PTKs since they first became available without prescriptions last year, according to Doug Fogg, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $ 2,500.
Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among passionate genealogists—and supports businesses that offer to search for a family's geographic roots.
Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.
But some observers are skeptical. "There is a kind of false precision being hawked by people claiming they are doing ancestry testing," says Troy Duster, a New York University sociologist. He notes that each individual has many ancestors—numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father's line or mitochondrial DNA, which is passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.
Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don't rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may have a lot of data from some regions and not others, so a person's test results may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.
In Paragraphs 1 and 2, the text shows PTK's ______.
A．easy availability
B．flexibility in pricing
C．successful promotion
D．popularity with households

I believe in people, in sheer, unadulterated humanity. I believe in listening to what people have to say, in helping them to achieve the things which they want and the things which they need. Naturally, there are people who behave like beasts, who kill, who cheat, who lie and who destroy. But without a belief in man and a faith in his possibilities for the future, there can be no hope for the future, but only bitterness that the past has gone. I believe we must, each of us, make a philosophy by which we can live. There are people who make a philosophy out of believing in nothing. They say there is no truth, that goodness is simply cleverness in disguising your own selfishness. They say that life is simply the short gap in between an unpleasant birth and an inevitable death. There are others who say that man is born into evil and sinfulness and that life is a process of purification through suffering and that death is the reward for having suffered.
I believe these philosophies are false. The most important thing in life is the way it is lived, and there is no such thing as an abstract happiness, an abstract goodness or morality, or an abstract anything, except in terms of the person who believes and who acts. There is only the single human being who lives and who, through every moment of his own personal living experience, is being happy or unhappy, noble or base, wise or unwise, or simply existing.
The question is: How can these individual moments of human experience be filled with the richness of a philosophy which can sustain the individual in his own life？ Unless we give part of ourselves away, unless we can live with other people and understand them and help them, we are missing the most essential part of our own human lives.
There are as many roads to the attainment of wisdom and goodness as there are people who undertake to walk them. There are as many solid truths on which we can stand as there are people who can search them out and who will stand on them. There are as many ideas and ideals as there are men of good will who will hold them in their minds and act them in their lives.
A. listening to people's opinions
B. revolutionary changes
C. being happy or unhappy
D. the way it is lived
E. we give part of ourselves away
F. many roads to the attainment of wisdom
G. as a short gap between birth and death
We are living in a periods of
