[基础写作参考范文]

Dear Zhang Hua,

It’s three months since I heard from you last time. Now I want to tell you an impressive story happened on my first lesson.

On hearing the bell, students ran into the classroom as quickly as they can, except a boy Li Ming, whose father died a month ago. Late as usual, he stood outside the classroom, silently, but I signed to him to come in. 　In the middle of the class, I heard someone sobbing, only to find that it was the right boy, so I walked to him and asked what had happened . With tears in his eyes, he told me that his mother was ill and he had to take some medicine for her. Moved by his words, I praised him for his deeds and decided to sing a song named “Mother” for the students and the whole class applauded

From the story I feel we should respect our parents and do our best to help them

Do you think so? I’m looking forward to your reply.

Yours truly,

Li Hong
