三、阅读理解(共20小题;每小题2分,满分40分)

请阅读下列短文,从每题所给的四个选项(A, B, C和D)中,选出最佳选项,并在答题卡上将该选项的标号涂黑。

When I get off the bus, I’m usually greeted by the sounds of news on CNN. My father welcomes me, and I help him with the usual things—changing the channel and some other tasks. My father has a disease that makes him unable to walk. Despite his disability, my father has always been my role model.

In my first year at middle school, my grades slipped greatly. My father told me I could improve. I currently maintain a B plus average, and he confidently supports me in all my academic efforts. He is against violence to the best of his ability. Love is his most important tool,and he makes sure we know that violence is never the answer.

He urges me not to fear,but to believe in what I think is right.“No matter what anyone tells me,”he says,“I believe what I choose. If someone is discriminating against you for who you are, they don’t deserve your time.”My friends are the most caring people I’ve met, because I realize that they don’t judge me, and they like me as I am.

I’ve always found it strange that people pity me because of my father’s condition. He’s not inferior(次于) to anyone. His disease doesn’t hold him back. He’s normal person.

When I see disabled people out in public, I consider them equal to any other individual. No one is superior to anyone for any physical reason. I’ve known that from that day on, thanks to my dad.

“Anything else?”I’ll ask.

“No, that’s fine.”

As I walk to my room, I think my dad who teaches me the most important things I’ll ever need to know. My father is in no way inferior to anyone else. If anything, he’s even better.
