Three years ago I failed an important exam in my life and became a student in a ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, I found the teachers patiently and considerate. Besides, I enjoyed the friendly atmosphere in class. I decided make the best of it. I worked hard and get along well with my teachers and classmates. Whenever I had difficulties, they were always available. Soon, I became one of the top student in my class, and which greatly increased my confidence and got him motivated.

My experience tell me that it is not what you are given but how you make use for it that determines who you are.

某建筑工地进行主体施工，搭设脚手架外侧未挂设密目式安全网，当日风很大，张某从楼底下经过，突然从五楼楼板边缘处掉下一块1M长4CM×6CM的方木，正好击中张某头部（未戴安全帽）经送医院无效死亡请判断下列事故原因分析的对错。

主要是风太大风吹落方木所致
