A Person I Will Never Forget The person I will never forget is my English teacher.Her name is Linda.She is a little fat with a long flower dress.In fact,when I was in primary scool,Ididn't really like English.But when I met her and in her classes,I felt happy and excited.Even my heart full of curiosity.Then I became more interested in English. Linda has ever been to England to know more English culture and education for three months.When she came back,she had a new way to teach.Her classes was full of vigor,quite exciting! Now I always talk with her in English and ask some questions.She gives me help and something more important.I will never forget you,Linda. PS:If somewhere is wrong,please tell me.Thanks.
