As far back as I can remember, I’ve always known that my brother was different. At first I thought this was a  31   thing. But when I got older I learned the truth. My brother had autism (孤独症) and Attention Deficit Disorder (儿童多动症) — serious  32   conditions. At 15, he  33   like a 7-year-old child. When he was little, I didn’t  34   it as much. But as he got older, it became more obvious. When something didn’t go his  35  , he got angry and it took hours to  36   him down. He would talk to himself and play with string. We could never  37   to give him his medicine, otherwise he’d go wild. I was always  38   when we took him anywhere, and I never wanted to bring any of my friends  39   with me.
When I was 10,  I felt like I couldn’t  40   it any more. I’d shout at him for being different and would ask  41   he couldn’t be normal. Of course, he had no  42   what I was talking about. It became very hard,  43   when a friend of mine didn’t want to come over  44   her mom had said my brother was dangerous. Our fights  45   up until one day he came up to me. He gave me a big  46  ,  like he was saying, “I don’t know what I did  47  , but I hope you still love me.” At that moment I realized that I’d better learn to  48   him.
As I’ve gotten older, I’ve learned how  49   I really am. Having him as a brother has made me kinder and more patient. No matter how busy my  50   is, he’ll always listen to my problems. I worry about his future, but I know he’ll always be loved.
