一、注意事项  1.《申论》考试,与传统作文考试不同,是对分析材料的能力、表达能力的考试。  2.作答参考时限:阅读资料40分钟,作答110分钟。  3.仔细阅读给定的资料,按照后面提出的“申论要求”依次作答。 二、资料  1.今年2月,南昌市一名15岁的初中生因迷恋电脑游戏而离家出走,竟然连续 24天不到学校上课,也不回家,整天泡在游戏机室。这些电脑游戏室24小时经营,提供“吃住玩一条龙”服务。  2.山东德州一位16岁的少年玩遍当地游戏机室仍觉不过瘾,竟从家中偷了4000元,先后赴津入沪“上档次”,周游了两个多月。  在新闻媒体频频曝光这些事件后,人们发现,“游戏机病”已像瘟疫一样在全国中小学生中蔓延。部分城市初步调查,至少有10%的中小学生沉迷于玩游戏机,有的城市甚至达到20%至30%。  3.更出乎人们意料的是,电子游戏机无异于“电子海洛因”,是诱发青少年犯罪的罪魁祸首。武汉的精神卫生专家研究分析接触到的病例后告诉记者,青少年一旦沉迷于游戏机,即会产生愈来愈强烈的心理依赖和反复操作的渴望,不能操作时便出现情绪烦躁、抑郁等戒断症状。这种成瘾症状和戒断症状同时存在的特征,与毒品海洛因的成瘾行为特征极其相似。  4.武昌发生的7名青少年持刀伤害抢劫案,造成2名学生重伤住院。他们抢到钱后,都用于玩游戏机。西湖区吴家山农场3名14岁的少年沉溺于游戏机,在近两个月时间盗窃作案十多起,盗得财物价值数万元。  一位多年主办未成年人涉嫌犯罪案的检察官说,去年由于玩游戏机引发犯罪的已占青少年犯罪案的10%。  5.近一段时间以来,各地已采取强有力措施整治游戏机室。然而,彻底根治游戏机这一顽症,却并非易事。  管理不严、执法不严是症结所在。部门职责难分,游戏机室的开办需要公安、文化、工商三部门审批,三证俱全方可营业,可调查发现,现在大部分游戏机室证照不全或无证经营,有一城市电子、电脑游戏机室达3000余家,八成是无证经营。

用不超过350字的篇幅,提出解决给定资料所反映问题的方案。要有条理的说明,要体现针对性和可操作性。

单项选择题

British cancer’ researchers have found that childhood leukaemia is caused by an infection and clusters of cases around industrial sites are the result of population mixing that increases exposure. The research published in the British Journal of Cancer backs up a 1988 theory that some as yet unidentified infection caused leukaemia--not the environmental factors widely blamed for the disease.

"Childhood leukaemia appears to be an unusual result of a common infection," said Sir Richard Doll, an internationally-known cancer expert who first linked tobacco with lung cancer in 1950. "A virus is the most likely explanation. You would get an increased risk of it if you Suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection. " Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in children around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the amount of population mixing going on in the area, as large numbers of construction workers and nuclear staff moved into a rural setting. "Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are incomers or locals, are at a higher risk if they are born in an area of high population mixing," Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer.

Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease.
