【正确答案】正确答案： In the picture presented to us, five workmen are passing through a construction site, one of whom, without a safety helmet, is unfortunately to be hit by a brick. The result can be imagined. The picture above reminds us that, without safety, life goals are just a castle in the air. On the micro level, safety concerns about individuals and their families; on the macro level, it relates to the social development and stability. Unfortunately , a great many people have not been awakened to the importance of safety. Undervaluing safety is a problem pervasive throughout our society. The massive explosion in Tianjin port is the best illustration of the above points. This tragic accident injured hundreds of people, killed 114 persons, and finally caused inestimable losses. Consequently, we must attach enough attention to safety and give priority to prevention. On the one hand, safety education should be strengthened in all walks of life, aiming to make all people have a clear understanding of self-safety and gradually form good safety habits. On the other hand, the implementation of safety system should be inspected in time to promptly the hidden hazards and take corresponding measures.
