材料一：“自孔孟以至宋元明之理学家，侧重内心生活之修养，其结果为精神文明。三百年来之欧洲，侧重以人力支配自然界，故其结果为物质文明。”“所谓精神与物质者：科学之为用，专注于向外，其结果则试验室与工厂遍国中也。……抑知一国偏重工商，是否为正当之人生观，是否为正当之文化，在欧洲人观之，已成大疑问矣。……对于物质文明，不胜务外逐物之感。厌恶之论，已屡见不一见矣。此精神与物质之轻重，不可不注意才一也。”

——张君劢《人生观》（1923年2月）

材料二：科学不但无所谓内外，而且是教育同教养最好的工具。因为天天求真理，时时想破除成见，不但使学科学的人有求真理的能力，而且有爱真理的诚心。无论遇见什么事，都能平心静气去勇于研究，从复杂中求简单，从紊乱中求秩序，拿论理来训练他的意想。……了然于宇宙生物心理种种的关系，才能够知道生活的乐趣。

——丁文江《玄学与科学》（1923年4月）

材料三：欧洲的科学已经到了根深蒂固的地位，不怕玄学鬼来攻击了。几个反动的哲学家，平素饱餍了科学的滋味，偶尔对科学发几句牢骚，就像富贵人家吃厌了鱼肉。……一到中国，便不同了，中国此时还不曾享着科学的赐福，更谈不上科学带来的“灾难”。我们试睁开眼看看：这遍地的乩坛道院，这遍地的仙方鬼照相，这样不发达的交通，这样不发达的农业——我们哪里配排斥科学？

——胡适《科学与人生观》序

材料四：达尔文的《物种起源》出版后，宗教势力不甘心自己的失败，他们组织信徒出版刊物，不断集会大造声势，叫嚣“打倒进化论”、“拯救心灵”、“粉碎达尔文”，他们不准把《物种起源》放在剑桥大学三一学院的图书馆内。1864年，有30位皇家学会会员与40位医学博士，联名发表宣言反对达尔文。

——解恩泽《科学蒙难集》

材料五：赫胥黎说：我认为，人类的高贵身分并不会由人猿同祖而降低。因为，只有人才具有创造可理解的和合理的语言的天才，就凭这种语言，在他生存的时期逐渐积累经验和组织经验；而这些经验对其他动物来说，当个体生命结束的时候就会完全丧失了。因此，人类现在好像站在大山顶上一样，远远高于他的卑贱的伙伴的水平，改变了他粗野的本性，放射出真理和智慧的光芒。

——《达尔文》

材料六：严复表述的振聋发聩之处在于“生存斗争”的达尔文主义学说，及其阴郁的推论——“自然选择”。严复创造了两个汉语语汇来表达这些概念：“物竞”和“天择”。“物竞者”，严复说，“物争自存也。天择者，存其宜种也”。 通过将两者合而为一，严复创造了新的四言习语——“物竞天择”——来指称这两个深具影响的社会达尔文主义口号。

请回答：

2016年6月12日，***对近期校园暴力频发作出重要批示指出，校园应是最阳光、最安全的地方。校园暴力频发，不仅危害未成年人身心健康，也冲击社会道德底线。教育部要会同相关方面多措并举，特别是要完善法律法规、加强对学生的法制教育，坚决遏制漠视人的尊严与生命的行为。

    Sometimes people are not clear about what kind of food is healthy, and what kind of food may do harm to our health. The USDA has prepared a food guide to help people learn about which kind of food is the healthiest to eat. The food guide describes six main food groups: meat (like fish and chicken), dairy (like milk and cheese),grains (like bread and rice), fruit and vegetables. The last group is fats and sweets. The USDA also suggests how much of each food group is healthy to eat daily. Though this guide was prepared by the US government, it is very useful for people all over the world.
    As a result of years of study, we know that too much animal fat is bad for our health. For example, Americans eat a lot of meat and only a small amount of grains, fruit and vegetables. Because of the way they eat, they have a high rate of cancer and heart disease. In Japan, people eat large amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live longer than anyone else in the world. However, when Japanese people move to the US, the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers, ice creams and other high-fat foods become popular in Japan, the rate of heart disease and cancer is going up there as well. People are also eating more meat and dairy food in other countries, in which the disease rate is going up along with the change of the way people eat. Doctors everywhere suggest people eat more grains, fruit and vegetables and less meat and dairy food.
    Eating healthily is important for children as well as their parents. When parents have poor eating habits, their children usually do, too. After all, children eat in the same way as their parents. When parents eat healthy food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors suggest parents give their children healthier food such as fruit, vegetables and juice.
    Everyone wants to live a long, healthy life. We know that the food we eat affects us in different ways. For example, doctors believe that fruit and vegetables can really protect people from many different diseases. On the other hand, animal fat can cause diseases. We can change our eating habits now and enjoy many years of healthy living.
