7．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，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 threeyearolds 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 lot of emails comparing photographs and biographical details，DNA testing proved the families'suspicions：the girls are probably fraternal（亲如手足的） 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（亲属）．The site that the Funks and Ramirezes used has a membership of 137people，with 15sets of twins and 7sets of siblings （兄弟，姐妹） whose relationships have been confirmed．
At a reunion Friday at Chicago's O'Hare International Airport，Mia Diamond Funk and Mia Hanying Ramirez shyly surveyed each other，and then reached for each other's hand．
DNA tests establish an 85percent probability that the girls are at least halfsisters．Scientists do 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 bring their 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．

分析 本文介绍了一对双胞胎姐妹通过网络最终得以团聚，其中收养她们的两个母亲在网上的交流起了非常关键的作用．
解答 12．D 推理判断题．根据文章第一段"Both families named their daughters Mia．The girls'mothers-Holly Funk and Diana Ramirez-met on a website for parents who had gone through international adoptions．After a lot of emails comparing photographs and biographical details，DNA testing proved the families'suspicions：the girls are probably fraternal（亲如手足的） twins．"可知，两位母亲虽然都给女儿取了Mia这个名字，后来在网上交流时才发现两个女孩长得很像，因此断定两个母亲取名时是无意的，仅是一种巧合，故选D，没有正当理由．
13．B 细节理解题．从文章第五段中的"The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin（亲属）．"可知，国际孤儿院网络以及网络组织用以使被收养的孩子找到亲属，故选B．
14．C 细节理解题．文章倒数第二段"Scientists do 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．"可知，科学家还没有女孩亲生父亲或母亲的DNA，因此不能作出确切的判断，故选C．
15．B 推理判断题． 根据第四段中""I was in shock，"said Ramirez，"Well，now this is for real．""可知，Ramirez一开始非常震惊，之后又说"好吧，现在这是真的了"，Ramirez感到惊讶，但也接受了事实，故选B．
