【答案】Dear students，
   Over the past few months，COVID-19 has been a big challenge in China and even in the world.It has such a strong impact on our life and study.In view of the fact that COVID-19 may still break out again，I am entrusted by the student union to call on all students in the school to do a good job in self-protection.
   First of all，you should develop good personal hygiene habits，washing you hands frequently.In addition，when talking to others，you'd better keep a safe distance and don't take your face mask off.What's more，avoid going to crowded places and obey the public order of the school.If you go to the dinning hall，obey the orders and line up.
   Let's join hands to scientifically prevent and cut off the transmission channels and prepare for a promising future.
