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（親如手足的） 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（親屬）．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 本文介紹了一對雙胞胎姐妹通過網絡最終得以團聚，其中收養她們的兩個母親在網上的交流起了非常關鍵的作用．
解答 12．D 推理判斷題．根據文章第一段"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（親如手足的） twins．"可知，兩位母親雖然都給女兒取了Mia這個名字，后來在網上交流時才發現兩個女孩長得很像，因此斷定兩個母親取名時是無意的，僅是一種巧合，故選D，沒有正當理由．
13．B 細節理解題．從文章第五段中的"The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin（親屬）．"可知，國際孤兒院網絡以及網絡組織用以使被收養的孩子找到親屬，故選B．
14．C 細節理解題．文章倒數第二段"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，科學家還沒有女孩親生父親或母親的DNA，因此不能作出確切的判斷，故選C．
15．B 推理判斷題． 根據第四段中""I was in shock，"said Ramirez，"Well，now this is for real．""可知，Ramirez一開始非常震驚，之后又說"好吧，現在這是真的了"，Ramirez感到驚訝，但也接受了事實，故選B．
