Birth order﹣﹣﹣does it matter？ Are you different because you are the first， second， or third child in your family﹣﹣﹣or maybe the last of nine？

    A study found that first﹣borns have an average（平均的）IQ that is three points higher than people who fall into a different place in the birth order， perhaps because first﹣borns often help younger brothers and sisters， which improves their own skills． In 2007， an international organization of CEOs found that 43% of CEOs are first﹣borns ，33% are middle children， and 23% are last﹣borns． First﹣borns are more likely （可能的）to be doctors and astronauts and get higher pay．

    If first﹣borns are more successful， last﹣borns are generally more agreeable． They are also more likely to be funny， possibly to get attention from all the bigger people at the dinner table． Mark Twain and Stephen Colbert were both the youngest in large families， and Jim Carrey was the youngest of four． According to a 2007 Time magazine article， "The power of Birth Order，" last﹣borns are more likely to be artists and successful businessmen．

    Then there are the middle children； we have not ignored（忽视） them! Many middle children are short of one﹣on﹣one time with their parents． They often feel short﹣changed： the oldest gets more rights， and the youngest is "spoiled（宠坏的） "．Though they may be ignored， middle children are more likely to grow into easygoing adults．

    Many factors（因素）make us who we are， but if the research is correct， birth order may be one of the most important factors．
