根据下列文章，回答26～30题。

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 a 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 years, 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 $2500.

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 Trey 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.

1.根据下列材料请回答 26～30 题：BToday there are policemen everywhere, but in 1700, London had no policemen at all. A few old men used to protect the city streets at night and they were not paid.About 300 years ago, London was starting to get bigger and more and more people began to live there. The city was very dirty and many people were poor. There were so many thieves who stole money in the streets that people stayed in their homes as much as possible.In 1750, Henry Fielding started to pay a group of people to stop thieves. They were like policemen and were called "Bow Street Runners" because they worked near Bow Street.Fifty years later, there were 120 "Bow Street Runners", but London had become very big and needed more policemen. So in 1829, the first Metropolitan (or London)Police Force was started with 3,000 officers. Most of the men worked on foot, but a few rode horses. Until 1920 all the police in London were men.Today. the London police are quite well paid and for the few police officers who still ride horses, the pay is even better than for the others.第 26 题 In 1700, the men who protected the streets were paid __________.A． a fewB． nothingC． a littleD． a lot

2.根据下列文章，回答31～35题。During the past generation， the American middle-class family that once could count on hard work and fair play to keep itself financially secure has been transformed by economic risk and new realities. Now a pink slip， a bad diagnosis. or a disappearing spouse can reduce a family from solidly middle class to newly poor in a few months.In just one generation， millions of mothers have gone to work， transforming basic family economics. Scholars， policymakers， and critics of all stripes have debated the social implications of these changes， but few have looked at the side effect family risk has risen as well. Today's families have budgeted to the limits of their new two-paycheck status. As a result they have lost the parachute they once had in times of financial setback- a back-up earner （usually Mom） who could go into the workforce if the primary earner got laid off or fell sick. This “added-worker effect” could support the safety net offered by unemployment insurance or disability insurance to help families weather bad times. But today， a disruption to family fortunes can not longer be made up with extra income from an otherwise-stay-at-home partner.During the same period， families have been asked to absorb much more risk in their retirement income. Steelworkers， airline employees， and now those in the auto industry are joining millions of families who must worry about interest rates， stock market fluctuation， and the harsh reality that they may outlive their retirement money. For much of the past year. President Bush campaigned to move Social Security to a savings-account model， with retirees trading much or all of their guaranteed payments for payments depending on investment returns. For younger families， the picture is not any better. Both the absolute cost of healthcare and the share of it borne by families have risen-and newly fashionable health-savings plans are spreading from legislative halls to Wal-Mart workers， with much higher deductibles and a large new does of investment risk for families‘ future healthcare. Even demographics are working against the middle class family， as the odds of having a weak elderly parent- and all the attendant need for physical and financial assistance have jumped eightfold in just one generation.From the middle-class family perspective， much of this， understandably， looks far less like an opportunity to exercise more financial responsibility， and a good deal more like a frightening acceleration of the wholesale shift of financial risk onto their already overburdened shoulders. The financial fallout has begun， and the political fallout may not be far behind.第31题：Today\\\'s double-income families are at greater financial risk in thatA．the safety net they used to enjoy has disappeared.B．their chances of being laid off have greatly increased.C．they are more vulnerable to changes in family economics.D．they are deprived of unemployment or disability insurance.
