×年×月×日8时20分,×市×化塑制品厂发生火灾,整个厂房被烧毁,造成直接经济损失达127.6万元。
当日8时上班后,工人孙××在该化塑制品厂压球车间门口西侧用电焊焊接压模。焊接现场的周围除一条3m宽的通道外,堆满了袋装成品浮球及废料,还有数个装丙酮、乙烷的铁桶。8时20分左右,拌料员谷××要在孙××作业处西侧约1.5m左右的地方,从铁桶中抽取丙酮,即告诉孙××要先停止电焊,孙××同意后便离开作业处。谷××用塑料管从铁桶中向塑料桶中抽取丙酮,由于操作不当将丙酮洒在水泥地面上,谷××没有采取任何措施就离开了现场。孙××回到作业处,没有检查也没有采取任何防护继续电焊。在焊接约3cm长的一段接缝时,电焊溅起的火花将洒在地上的丙酮点燃。孙××见起火用正在焊接的方模去压地上的火苗,但火苗仍然四溅。孙××与另一名工人先后取来3只灭火器,均未启动。火借风势迅速蔓延,整个厂区被大火吞噬。直到11时,大火才被扑灭。
事故发生后,×市××区人民检察院受理了此案,这起火灾事故是由于违章堆放危险品遇明火而引起,谷××等4人对此负有责任。经现场勘查和调查认定,谷××、孙××在生产过程中,违反规章制度,导致发生特大火灾,造成集体财产遭受严重损失,他们的行为触犯《中华人民共和国刑法》一百一十四条的规定,构成重大责任事故罪。厂领导王××和厂长刘××身为企业管理人员,不认真履行职责,对厂内事故隐患熟视无睹,对工人的违章作业放任自流,以致由于操作工人在事故隐患区域作业而发生特大火灾,他们的行为触犯了《中华人民共和国刑法》一百八十七条的规定,构成玩忽职守罪。

Sofia Coppola’s "Lost in Translation" is a funny, bittersweet movie that uses cultural dislocation as a metaphor for people who have gotten lost in their own lives. The movie contains priceless slap-stick from Bill Murray, finely tuned performances by Murray and the beautiful Scarlett Johansson and a visual and aural design that cultivates a romantic through melancholy mood. In only her second feature, Coppola has made a poised, intelligent film that nicely balances laughs with a poignancy rarely seen in American movies. If Focus Features markets "Lost in Translation" carefully, this most original comedy could win audiences well beyond art houses.
Bob Harris (Murray) is a grumpy movie star in town to shoot a whiskey commercial. He is not only plagued by jet lag and gloom over a deteriorating marriage of many years, he is also in the midst of a midlife crisis that dampens his spirits but not his wit.
Charlotte (Johansson) , the neglected wife of a photographer, experiences a similar air-condl-tioned nightmare. Married two years, she already feels lost in the relationship, unable to partici-pate in her husband’s career or pinpoint what she wants out of life. When she ventures into the city, she is confronted by a distorted version of Western modernity.
These two people discover each other late at night at the bar. Neither one can sleep. A friend-ship evolves in their mutual isolation.
Coppola sees in Tokyo’s crowded, neon-lit urban landscape a society estranged from its own culture. The night is filled with pleasure-seekers obsessed by games, toys and American pop culture. Only when Charlotte takes a train to Kyoto is she able to experience the old Japan of ancient temples and gardens, tea houses and kimono-clad figures. This role fits Murray like his own skin. A middle-aged burnout who sees no challenges on his horizon gradually changes into a man revitalized by another alienated soul. His comic touch enriches the character with a self-deprecating wit and in a few sequences, a rubbery physicality that earns sustained laughs. Johansson makes Charlotte’s loneliness and disillusionment palpable as the woman is cut off from life in ways she never imagined.
Using high-speed film stock, cinematographer Lance Aeord gives the glaring neon and num-bingly sleek interiors a kind of romantic sheen. The score produced by Brian Reitzell created out of Japanese musical themes and "Tokyo dream-pop" adds to the sense of an Eastern city that has succumbed in large measure to Western culture.

A.submit to
