Christmas is for giving and sharing, for getting together with family and friends. But mostly it’s for love. I had not believed this until a student, who was called Mark, gave me a wonderful gift one Christmas.
Mark was an 11-year-old orphan (孤儿) who lived with his aunt, a middle aged woman greatly annoyed (使烦恼) with the burden (负担) of 1 for her dead sister’s son.
I had not 2 Mark especially until he began staying after class each day to help me tidy up the room. We did this quietly, not speaking much, but enjoying the time of the day. When we did talk, Mark spoke mostly of his 3 , who had always spent much time with him before she passed away. 4 Christmas came near, however, Mark failed to stay after school each day. I 5 him one afternoon and asked why he no longer helped me in the room. “I was making you a 6 ,” he said confidently (有信心地) in a low voice. “It’s for Christmas.” With that, he left the room in a hurry. He didn’t stay after school any more after that. Finally 7 the last school day before Christmas. Mark walked slowly into the room late that afternoon. “I have a present,” he said. “I hope you like it.” He held out his hand, and in it was a tiny wooden box. “It’s beautiful, Mark. What’s in it?” I asked, opening the top to look 8 . “Oh, you can’t see it,” he replied, “and you can’t touch it, or taste it or feel it, but mother always said it makes you feel good all the time, warm on cold nights, and safe when you’re 9 .”
I looked into the 10 box. “What is it, Mark,” I asked, “that will make me feel so good?” “It’s 11 ,” he said softly, “and mother always said it’s best when you give it away.” And he turned and quietly left the room.
So now I 12 the small box on the piano in my living room. Yes, Christmas is for joy, songs and nice gifts, but mostly, for love.

只回答 5为什么选D 我选的A不对吗 7为什么选C我选的B怎么不行 请说明一下理由 谢谢

5题选stopped而不选caught,从词义上说catch有捕捉,赶上,抓住的意思,这句话的翻译是一天下午我拦住了他,用stopped比较恰当.
7题属于倒装句,正常语序为the last school day before Christmas came,return表示返回,一般不用在时间上,时间是不能倒流的.
