Two years ago, the Funk family of suburban Chicago adopted a Chinese baby girl who had been abandoned on a sidewalk near a Yangzhou textile factory. Last year and halfway across the United States, the Ramirez family of suburban Miami adopted a girl who had been abandoned a week later on the same spot. Both families named their daughters Mia. It turns out, a first name and Chinese heritage aren't the only things the three-year-olds have in common. The girls' mothers--Holly Funk and Diana Ramirez--met on a website for parents who had gone through international adoptions. After a flurry of e-mails comparing photographs and biographical details, DNA testing proved the families' suspicions: The girls are probably fraternal twins. "I was in shock," said Ramirez, who lives with her husband Carlos in Pembroke Pines, Florida. "Well, now this is for real." The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin . The site that the Funks and Ramirezes used has a membership of 137 people, with 15 sets of twins and seven sets of siblings whose relationships have been confirmed. At a reunion on Friday at Chicago's O'Hare International Airport, Mia Diamond Funk Mia Hanying Ramirez shyly surveyed each other, then reached for each other's hand. DNA tests established an 85 percent probability that the girls are at least half sisters. Scientists did not have a biological parent to test and reach a greater certainty, but given their ages and physical similarities, experts say it is likely they are fraternal twins. Douglas and Holly Funk hope to take Mia to Miami in October. Both sets of parents say they are committed to staying in touch and often let the twins talk to each other on the phone. Experts are still not 100 percent sure that the two girls are fraternal twins because _ . A) DNA tests are still not accurate enough B) the two girls were born by different parents C) the DNA of a biological parent is still missing D) one girl is born a week later than the other

Q: Shanghai Faces Aging Problem The population of citizens aged above sixty in Shanghai City in east China has reached 2.46 million, accounting for nearly 18.6 percent of its total population, a local official said today. Shen Zhenxin, deputy director of Shanghai Civil Affairs Bureau, says that the figure mainly shows a social problem brought by the increase in the numbers of elderly people, according to Tuesday's China Daily. Shanghai was the first city in the country to have an aging society-with 10.07 percent of the population of pensionable age in 1979. It is predicted(told in advance)that the rise in the city's elderly population will reach its top between 2025 to 2030, the newspaper reports. A recent survey(study)also shows that the population above the age of 60 in China has amounted to(reached)some 132 million so far, and the figure is increasing by 3.2 percent each year. "Yet fewer children have been born these years, so the social security system should be improved as soon as possible," said Shen. Shanghai has chosen some communities as pilot neighborhoods to carry out a help-each-other program in an attempt to solve the problem. People can help take care of the elderly people, and they in turn will be looked after by others when they get old, according to China Daily. What should the society do to carry out the help-each-other program? A) Elderly people help each other. B) The old and the young help each other. C) The young help the old. D) The old help the young.

Today,I watch over seven branches. We have 187 employees and $15 million in sales. While I'll never be what my teachers might have wanted,I am a success-on my own terms.
