问题解答：
it is true that one's personality is shaped by the environment that one lives in, but once the personality has been formed, in my opinion, it can not be easily changed.
there are many factors that may influence one's character, such as family and educational background, many people agree with the important role of environment. i think, one's life experiences will help a lot to form his personalility. if we live a quite smooth and calm life, we may become optimistic and happy people. while if we live a life full of up and down we will possibly have a strong and tough personality.
