This summer vacation, I watched a moviecalled “ Homeless to Harvard”.
A movie about Liz Murray reality, atouching inspirational videos. This movie is talking about a girl was born inthe United States of America'sslums. Her family is very terrible. When she was 8 years old, she decided to wanderin the corner of the city with her friend. They slept in the subway station,steal food in supermarket. One day, her friend can’t stand this life, lefther.
With the growing slowly, Liz knew, onlyreading success can change the fate of its own. She began to study; she used 2years, finished four years courses of Senior High School.
This storygives me power, even it might seen crazy. I do thing that I haven’t do thatbefore, I might say:“I can’t! I will not finish this!”After the movie, I know that: Nothingis impossible, depending on how much you pay.
