o to the world’s parents sounded the alarm, but also for mankind sounded the alarm! With my eyes closed, I can imagine how the families of the victims were devastated, how they plained about injustice, how many happy families lost their laughter and how many children lost their source of happiness. The occurrence of a tragedy is unpredictable, the beginning of a tragedy is something people don’t want to see, and the extension of tragedy is endless. Life is something that should be taken care of all the time, but people always ignore it and regret it when they lose it. Caring for life and cherishing life should be the concept that everyone should have in mind at all times. It is those little carelessness and laxity that make tragedy e into being and make life disappear... Life is fragile and needs protection and careful care. Life is precious. If you lose it, you will never have it again. At the same time, life is fair. If you do wrong and lose it, it will not give anyone a chance to e back... Human beings, How many lives have passed away has sounded the alarm for us, how many tragic stories should let us reflect, it’s time for us to build the defense line of life!
