【简答题】
The night of graduation, I was afraid. Two hundred people were sitting out there. I felt tense and I wanted to run away, 1 I couldn’t! After all, my own children were sitting in front of me with many other persons. I couldn’t be a coward(懦夫) before 2 . When I ended the speech, I was 3 at the cheering. And I never forget the first time I received the cheering in my life. Flowers arrived 4 my brothers and sister. My husband gave me silk roses. The reporters came with 5 and recorders and lots of questions. There were tears and hugs and congratulations. Sometimes, I sit down and 6 the tape of my graduation speech. I hear myself say to the audience, “Don’t’ give up your 7 in life. Anything can happen if you believe. It means hard work, but 8 sure that you can do it, with God’s help.” And then, I remember mother’s 9 to me , a young girl: “Hurry, Gin, you’ll be late for school.” Yes, Mom, I was late 10 school, but it was sweeter for waiting. I only wish you and Dad could have been there to see your daughter and granddaughter in all their show and speech. 小题1: A.and B.then C.so D.but 小题2: A.them B.themselves C.him D.himself 小题3: A.worried B.worrying C.surprised D.surprising 小题4: A.at B.in C.to D.from 小题5: A.books B.newspapers C.cameras D.cars 小题6: A.put up B.put down C.put on D.put off 小题7: A.speech B.ideas C.dreams D.love 小题8: A.let B.take C.get D.make 小题9: A.shout B.shouting C.call D.calling 小题10: A.to B.for C.of D.with
