    It is well known that twins are closer to each other than most brothers and sisters; after all, they probably spend more time with each other. In Britain there was the famous case of the silent twins, June and Jennifer Gibbons, who refused to talk to anyone but each other.

However, these special relationships are the result of lives spent almost completely in each other’s company. What happens when twins do not grow up together? Are they just like any other strangers, or are there still special similarities between them? Professor Tom Bouchard who works in the University of Minnesota set out to find the answer to this question. He followed sixteen pairs of twins, who lived in different families. Each twin was then interviewed about their life.

The results were surprising. Many of the twins were found to have the same hobbies or habits, and some have suffered the same illnesses. A large number of the twins have had children at almost the same times; sometimes they have even given them the same names. But the most surprising similarities are to be found in the case of Jim Springer and Jim Lewis. The story of the “Jim Twins” made headline news across USA, and they even appeared on national television. Born in 1939, and brought up by different families at birth, both babies were named Jim by their new parents.

So what can be the explanation for these similarities? Research into the lives of twins makes us believe our personalities may be at least partly due to nature. On the other hand, some surprising coincidences（巧合） do happen all the time, not just in the lives of twins.
