My worst experience when I was eight years old . I could only ride the bike unskilfully . One day , my father and I went to the park by bike . We talked very happy . Unfortunutely , I tripped from my bike . I felt pain . Then my father took me returned home .
My happiest experience was in the winter of 2007 . I went to Hainan with my parents and friends . We went there for one week . I played with my friends everyday . We also had very great meals . But I felt a little homesick .
would be most grateful."The operator paused,
