| Yesterday my English teacher asked each student write a composition title "The Greatest Achievement of My Life". I am not sure how to write about it. I"ve thought it over for a long time. I have done a great deal things. Coming to America, get a job and meeting new people were my achievement. I think my greatest achievement was learning English. Though sometime I don"t understand everything people are saying, but each day I get better and better. I told my teacher this was difficult composition to write. Above all, it is hard to measure everything you have done. | 1______ 2______ 3______ 4______ 5______ 6______ 7______ 8______ 9______ 10______ |
