学校教育在人的身心发展中起主导作用。

答案

参考答案:这种观点是正确的。具体分析如下:
学校教育对人的发展特别是对年青一代的发展起着主导作用,具体体现在以下几个方面:(1)教育是一种有目的的培养人的活动,它规定着人的发展方向。教育不管是有组织的或是无组织的、系统的或是零散的、家庭的或是学校的、社会的,都是有目的的培养人的活动,它以教育人为主要目的。学校教育能排除和控制一些不良因素的影响,给人以更多的正面教育,使人按照一定的思想政治方向发展,使年青一代健康成长。
(2)学校教育给人的影响比较全面、系统和深刻。学校教育是根据一定社会的要求,按照一定的目的,选择适当的内容,利用集中的时问,有计划、有系统地向学生传授科学文化知识,并进行一定的思想品德教育。而环境中其他方面的影响,往往是自发的、偶然的、片断的,是不能与学校教育相比拟的。
(3)学校有专门负责教育工作的教师。学校教育是通过专门培训过的教师来进行工作的,教师受国家的授权和社会的委托来教育学生。他们有明确的教育目的,熟悉教育内容,懂得教育的规律和方法,能自觉地促进学生的思想、学业、身心按照一定的方向发展。
随着社会的发展、科学技术的日益进步,教育对人发展的主导作用表现得越来越明显。

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.
