when I was a little boy,I used to live in a house with a yard and there were many people lived around me.In all of my neighborhoods,Mr Black gave me the biggest influence.
He was a physics teacher in a high school,every times when I came to his hoom to play ,he always talked to me about science and technology,that increased my intrest of science,that changes me a lot.
I haven't saw Mr black for a long time,now I miss him very much.
