When I was a young child, my parents often told me that it was time that taught a man everything. I didn’t understand and wondered why _31_ had such a big influence _32_ a person. I thought I could grow up quickly to find it out as an adult. But now, _33_ I come to knock at the door of adulthood, I feel _34_ to express my own opinion on this saying. I know that I am just a high school student with very few experiences. There are still many things waiting for me in the future, yet I would like to express myself in a childish voice.
I once read this sentence, “To make this world a happy place in which to live, you had better _35_ yourself and your heart, instead of the whole world.” I was shocked.

What we can do is just to make  _39_ suit the world. I think we should learn to accept _40_ life gives us, no matter whether it’s the spring sunlight or the winter snowfall, and try to be happy.
The pop song Grandmother by Jay Chou is my favorite. I’m deeply moved by this beautiful song. I always try to _41_ every pleasant thing in my life, but now I see that I don’t catch most of the pleasant moments. It is more likely that they slip by(流逝)and leave you _42_ regretful. I realize that I’m not just living for myself and that there are others I should _43_ such as my parents, friends, and so on. They all pay attention to my growing up, _44_ it’s just a little progress.
Everyone has his or her own _45_ towards life, positive or negative. It doesn’t  matter, I think. There is one rule that should be obeyed and that’s to make this world better.
