Childish Voice

When I was a young child, my parents often told me that it was time to teach a man everything. I didn’t understand and wondered why   36   had such a big influence   37   a person. I thought I could grow up quickly to find it out as an adult．But now,   38   I come to knock at the door of adulthood, I feel   39   to express my own   40   on this saying. I know that I’m just a high school student with very   41   experiences. There are still many things   42   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 to live, you’d better   43   youreself and your heart , instead of the whole world.” I was shocked. It made me think about life   44   . There are so many things around us that    45   our will. We can’t force life    46    our wishes.The earth won’t stop turning no matter whether we   47   it or not. What we can do is just to make ourselves  48  the world. I think we should learn to accept   49   life gives us, no matter whether it’s the spring sunlight or the winter snowfall, and try to be happy.

Deeply moved by the pop song Grandmother (by Jay Chou), I always try to   50   every pleasant thing in my life, but now I see I don’t catch most of the pleasant moments. It is more   51  that they slip by and leave you feeling   52   . I realize that I’m not just living   53   myself and that there are the others around me I should think of .They all pay attention to my growing up, even if it’s just a little progress. 

Everyone has his or her own attitude towards life, be it positive or   54    . It doesn’t matter, I think. There is one   55   that should be obeyed—and that’s to make this world better.
