My life is always filled with sadness and little joy.完形填空

原文：
My life is always filled with sadness andlittle joy.However,no matter what happens,I can always face it bravely.
Last year,I couldn’t believe the news that I was allowed to enter the only key high school in my hometown.Then I rushed to my home and told my parents.But my father didn’t seem as excited as I was.He just kept smoking without saying a word and my mother put her head down and couldn’t help crying.
I knew very well what my family was like.My mum had been ill in bed for 2 years.We lived a hard life and I couldn’t continue my schooling.I felt so upset but I could say noting to my parents.I decided to help my father with his work to support my family.
To my surprise,things completely changed before the beginning of the new term.My head teacher came to my family with some money,which had been raised by my schoolmates.He encouraged me,“Always have a dream.” With tears in my eyes,I stepped into the key high school.
I have been studying hard since I entered the high school.Whenever I meet difficulties,I always think of my teacher and schoolmates.I have a college dream and I must work hard for it,no matter how hard life is.Just as a great man says,“When one door shuts,another opens in life.
