预防猪流感Dear teacherI 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 sincerelyMike2009-10-1
