查看习题详情和答案>>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 (手足般的) 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 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.
1.. Both the adopted girls shared a first name ________.
A. because they both came from China
B. because of their physical similarities
C. because their US parents suspected they were twins
D. for no good reason
2. Why did the girls’ mothers meet on the Internet?
A. To compare photographs of the two girls.
B. To communicate with other people who had adopted children abroad.
C. To test their suspicion.
D. To exchange experiences on adopting children.
3.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
4.What would be the best title for the passage?
A. Adopted Twins Reunited on Internet
B. Adopted Twins Live happily in the US.
C. Suspicion Turned into Reality
D. The Story of Adopted Twins and Their Parents

I dreamed I had an interview with God.“So you would like to interview me?”God asked.“If you have the time,”I said.“My time is eternity.”God smiled,“what questions do you have in mind for me?”“What surprises you most about humankind?”God answered,“That they get bored with childhood,they rush to grow up,and then long to be children again.That they lose their health to make money... and then lose their money to restore their health.That by thinking anxiously about the future,they forget the present,such that they live in neither the present nor the future.That they live as if they will never die,and die as though they had never lived.”God’s hand took mine and we were silent for a while.And then I asked,“As a parent,what are some of life’s lessons you want your children to learn?To learn they cannot make anyone love them.All they can do is to let themselves be loved.To learn that it is not good to compare themselves to others.To learn to forgive by practicing forgiveness.To learn that it only takes a few seconds to open profound wounds in those they love,and it can take many years to heal them.To learn that a rich person is not one who has the most,but is one who needs the least.To learn that there are people who love them dearly,but simply have not yet learned how to express or show their feelings.To learn that two people can look at the same thing and see it differently.To learn that it is not enough that they forgive one another,but they must also forgive themselves.”“Thank you for your time,”I said humbly.“Is there anything else you would like your children to know?”God smiled and said;“Just know that I am here always.”
