     Some people may say a hero is someone older than you, someone you personally know,

someone who has done something everyone knows about, etc. I don't think a hero necessarily

has to be an older person or a close friend or a family member. My hero is younger than me,

but we are related. His name is Marcus. He is my cousin. He isn't necessarily a wise person

or someone who does something great every day, but he has taught me to appreciate some

of the simple things in life.

     I am now in 11th grade. When I was in 8th grade, Marcus had a brain tumor (脑瘤)

which had to be removed. Thankfully the tumor was benign (良性的). When the doctors

removed it Marcus lost his sight. He felt down only once. Ever since then, he has been an

extremely happy second-grader. He is very typical of a nine-year-old. He likes to tell jokes,

play new games, and he likes to play tricks on people, just like children at his age. I love

spending time with him. We go to movies whenever there is a good one and look after him

every chance I get.

     I say that Marcus helps to appreciate the simple thing in life. He doesn't have his sight and

 that causes me to realize how lucky I am to be able to see, to walk, and to talk. I can do

everything I need to. If everyone could see how happy and satisfied Marcus is and how

much he makes everyone around him happy, then they might just be able to better appreciate

the simple things in life.
