Dear sir or madam，
I have meet miss hao xiaoni’s for four years， being his teacher in “database structure” and her tutor in the experiment of “digital electronics”。In the class， her thinking was very active and she completely understood what i said in the lecture。 She showed her strong interest in computer science and often did further discussion with me after the class。 In particular， her experimental methods were so innovative and creative that the experiment done by her was often more intensive than required。 I was much impressed by her because of her quick thinking， serious logic and independence。 Besides， she was able to sort out various problems in the experiment， having the ability in debugging of both software and hardware。
Sincerely，
