　　There has been an argument on personality and individual’s development fo

　　r a long time. The key point of the dispute is which factor plays a more

　　important role, genes or training after birth? In my opinion, the latter is the

　　crucial complication, though genes are significant.

　　Although genes have great effects on one’s personality, environment plays

　　a more important role in his further development. Let’s take an experiment

　　for instance. There was a research on a couple of identical twins who were

　　born in a big city, but they were separated after birth. One was taken to a

　　poor suburban area, while the other remained in the city. Fifteen years later,

　　surely, the one in city grew tall, strong, extroverted and well educated. By

　　contrast, the other was short, thin, introverted and nearly illiterate. This well

　　demonstrates the importance of nurturing.

　　In addition, education, especially early education, is another key factor.When

　　children are very young, they try to imitate their parents’ behaviors, and

　　run into some manners. After going to school, different education systems an

　　d even different courses students taking will make influence on their

　　personalities and ideas. Students of science and technology subjects are good

　　at logical thinking, while students of arts usually think in terms of imagine.

　　As you can tell from my comments above, no one can choose his nature,but

　　one can be greatly successful after striving for himself or being well educated.

　　And no one can be successful relying on his genes without good environmen

　　t. So, in my opinion, environmental influence and education will ultimately

　　decide one’s personality and development.
