高锰酸钾中钾的化合价为+1价，则锰元素的化合价是(   )   A +1    B +4      C +6    D +7 答案：DAbout ten years ago when I was an undergraduate in college in New York, I was working as a practice student at my University's Museum of Natural History. One day while I was working at the cash register in the gift shop, I saw an elderly couple come in with a little girl in wheelchair.As I looked closer at this girl, I saw that she was seated on her chair. I then realized she had no arms or legs, just a head, neck and the trunk of the human body. She was wearing a little white dress with the patterns of red roses and yellow dots.As the couple wheeled her up to me I was looking down at the register. I turned my head toward the girl and gave her a wink(眨眼示意). As I took the money from her grandparents, I looked back at the girl, who was giving me the most beautiful, largest smile I have ever seenAll of a sudden her handicap was gone and all I saw was this beautiful girl, whose smile just melted me and almost instantly gave me a completely new sense of what life is all about. I immediately felt full of hope and confidence. She took me, a poor, unhappy college student, into her world, a world of smiles, love and warmth.               That was ten years ago, but I still remember it clearly as if it happened just yesterday. I'm a successful business person now and whenever I get down and think about the troubles of the world, I think about that little girl and the remarkable lesson about life that she taught me.【小题1】What was the writer a decade ago?A．A worker working in a university.B．A teacher teaching in a college.C．A clerk working in a museum.D．A university student who had not yet taken a degree.【小题2】What does the underlined world “handicap” in Paragraph 4 probably mean?A．Life difficulty.B．Troublesome problem.C．Failure in work.D．Physical disability.【小题3】How did the writer probably feel before meeting the disabled girl?A．She felt full of hope.B．She was filled with confidence.C．She felt unhappy because of poverty.D．She felt life was beautiful.【小题4】Which of the following title suits this passage best?A．A Disabled Girl.B．A Disabled Girl’s Smile.C．Full of Hope.D．Full of Confidence.
