It is necessary for students to take first aid courses
As our society is getting more and more colourful,something unimaged will suddenly happen to us.Therefore,students must take first aid courses and know how to protect themselves.These first aid courses are not only regarded as a way to prevent us from dangerous,but also thougt as the basd knowlegde for human beings.Some students might say these courses take too much time and they are useless.Howere,as we know,life is the most impartant thing,if you lose your life,everything will be meaningless.On the other hand,we can use these knowlegde which we have learned in first aid courses to save others'lives when some urgent things take place.
In a word,it is necessary for students to take first aid courses.It is good for everbody!
