dear teacher,

i really want to say thanks to you because you not only teach ue a lot of knowledge, but also are concerned about us. i still remember that you worried about our health last spring, when influenza a spreaded rapidly around the city. you, my dear teacher, asked us to wash hand and take a bath frequently. you also suggested us to open the windows and not go to the place having many people. you recommended us to drink more water and form a good habit. you came early and back late to spray drug. it was very painstaking.my dear teacher, thanks again.

best wishes!

　　yours sincerely

　　mike
