In order to fight against A-H1N1 flu, a lecture on “H1N1 and its Prevention”, is to be held in the school lecture centre at 2:00 pm this Wednesday.　　The lecture will be made by a professor from Beijing University and he will talk about how to prevent H1N1 flu and after that, our principal, Mr Luo, will tell us in details how to prevent H1N1 flu.　　Both teachers and students except Senior 3 students are required to attend the lecture.　　I think that the best defense against A-H1N1 is to use good hygiene by washing your hands and if you are sick, stay home from work, and keep sick kids home from school, and a respirator also is a good defense against A-H1N1 flu.　　Personally, such a lecture is very useful, so I do hope that more lectures like this should be held from time to time in our school in order to prevent diseases.
