1.假设你是李华,最近校学生会针对中学生的急救知识掌握情况做了一

Dear Headmaster I am a common student who is concerned about the school.I

am writing to you about the lack of the knowledge of first aid among our

students.recently,the student union made a survey on the present situation of

the students' mastery of first aid ,which implies that most students know the

number of the emergency center while show ignorance of artificial breathing,burn

or scald treatment and animal bite.As social animals,we should prepare ourselves

for the upcoming danger not only for ourselves but also crucially for people we

love and people we care for.in this situation,i strongly suggest the wide spread

of first aid knowledge informing our students the great importance of first aid

,which may include relevant leaflets,lectures and real people imitation.i hope

it can raise your attention.（名字+日期）
