Bo, a golden retriever, won this year's Dog Hero Award from the Ken L Ration dog food company. Bo acted1last June. Bo and his owners, Rob and Laurie Roberts, were going down the Colorado River in a 16-foot boat. The June2was Bo's first time in a boat.

    Laurie Roberts said, "Things were fine 3a 6-foot wave broke in front of us and filled the boat with water. Another big wave caught us from the back and turned the 4 over. "Rob was thrown clear, but Laurie and Bo were unable to move out 5the boat. "Every time I tried to 6, my head hit the boat, "Laurie said. "I hit the bottom of the river several times. I 7I was drowning(溺水). "

    Rob picked up the story, "I reached the land and 8 Laurie, "he said. "I saw Bo swim out from under the overturned boat. Then he9and dived（下潜）. Soon he came back up, pulling Laurie by the hair. "Laurie, who was 10 and breathless, tried to catch Bo. But the dog stayed out of reach as is knowing both of them would drown if Laurie pulled him under. Finally, Laurie caught Bo's tail. He pulled her 30yards to the land. Laurie was cut and bleeding, but she was afraid.

    In 1972, I returned to Miami Beach High School to give a speech to a dance class. After the1I asked the dance teacher if any of my English teachers was still there. He told me that Irene Roberts was in the class just down the hall.

    I was no one2in Miss Roberts' class—just another sport fan who didn't do very well in English. Yet I can't forget her respect for ideas and for her students. I realize now, many3later, that she is one of the best4I have ever had. I told the dance teacher that I'd like to say something to her, but I was afraid to5her right now. 

    The dance teacher told me that Miss Roberts would be6to see me. The dance teacher brought Miss Roberts into the hallway where stood this 32-year-old man she last7at the age of 18. "I'm Mark Medoff, "I told her. "You were my 12th grade8teacher in 1958. "She looked at me carefully for some time9didn't seem to remember who I was. At that moment I got so many things to say to her, but what I10said was: "Miss Roberts, I want you to know you were so important to me. "Hearing this, Miss Roberts began to weep and held me in her arms.

    Today l would like to tell you about my dream．

    My dream is a simple but great one．It is to be a teacher．①我从小就梦想做一名老师!②First of all，it is a pleasure for me to be with children ． They make me feel ③ happy and young．Furthermore，teachers play an important part in the development of children．They teach children and show them how to be good．When children grow up，they use the knowledge that they have learned to develop their motherland and make it beautiful. I think teaching is one of the ④    (value) things in the world．

    That’s all．Thank you !
