Question

      For years scientists have been arguing about whether nature or nurture (后天) decides what people

    will be like. Is it nature —what people are 1 with—that decides what they will be like? 2 is it nurture—what 3 to people when they are born —that decides what they will be like?

     Scientists have been studying twins to 4 if they can Hnd the answer,because twins start out with the 5 DNA. Sometimes twins don't live together at birth and grow up in different 6 and different places —so the nature is the same for both,but the nurture is different.

    When scientists 7 these twins in their later life,they some times find some surprising 8 .

    Jim Springer and Jim Lewis were adopted (收养) by two different families at birth. They first met each other again thirty-nine years 9 and discovered they had a lot in 10 . Both had been 11  twice. Their first wives were both named Linda and their second wives were both named Betty!

    Each twin had a son —one called his son James Alan and the 12 called his son James Alan,too. Their children each had a dog called “Toy”. They even arrived at their first 13 in the same color of car.

      So far twin 14 seem to show that both nature and nurture are important. What we have from birth,and how and where we live help to build 15 we are.
