Have you thought about what determines the way we are as we grow up? Remember the TV program Seven Up ? It started following the lives of a group of children in 1963. We first meet them as wide-eyed seven-year-olds and then catch up with them at seven-year intervals (间隔 )  : nervous  14-year-olds , serious  21-year-olds , then  grown-ups.
Some of the stories are inspiring ,others sad ,but what is interesting in almost all the cases is the  way  in which  the  children's early hopes and dreams are  shown  in their future lives, for example ,at seven ,Tony is a lively child who says he wants to become a sportsman or a taxi driver. When he grows up, he goes on to do both.  How about Nicki ,who says, "I'd like to find out about the moon. " and goes on to become a space scientist.  As a child, soft - spoken Bruce says he wants to help "poor children" and ends up teaching in India.
But if the lives of all the children had followed this pattern, the program would be far less interesting than it actually was. It was the children whose childhood did not prepare them for what was to come that made the program so inspiring. Where did their ideas come from about what they wanted to do when they grew up? Are children influenced by what their parents do ,by what they see on television ,or by what their teachers say? How great is the effect of a single important event? Many film directors ,including Stephen Spielberg ,say that an early visit to the cinema was the turning point in their lives.  Dr. Magaret  Mc Allister ,who has done a lot of research in this area ,thinks that the major influences are parents , friends and the wider society.
