参考范文：Dear Sally,I'm writing to share with you an experience I hadduring a recent learning activity.It took place at thecommunity center and was focused on Chinese cooking.The activity started with a brief introduction to theingredients and techniques for the dish.Then,we workedtogether to select the meat,vegetables and ingredients.Achef began to teach us how to cook!It was interesting tosee how exchange students experience different culturesfrom their own in cooking.Throughout the activity,we all learned how to cookChinese food thoughwe are not yet skilled at it.It wasagreat way to spend an afternoon together and we reallyenjoyed the experience.Yours,Li Hua
