题目:

在某水利工程施工工地,施工单位根据施工需要兴建的临时办公用房是一座四层砖混建筑物。第一层楼的一端是车间,另一端为原材料库房,库房内存放了木材、海绵和油漆等物品。车间与原材料库房用铁栅栏和木板隔离。搭在铁栅栏上的电线没有采用绝缘管穿管绝缘,原材料库房电闸的保险丝用两根铁丝替代。第二层楼是包装、检验车间及办公室。第三层楼为成品库。第四层楼为职工宿舍。由于原材料库房电线短路产生火花引燃库房内的易燃物,发生了火灾爆炸事故,导致17人死亡,20人受伤,直接经济损失80多万元。

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes---khaki pants and sports shirt---to the office. He hardly ever wears necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday.” “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing,” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale. Only 4 percent of employers said that casual dress has a negative impact on productive. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”
