（2010•冀州二模）

“A very disruptive(扰乱型的) six-year old child kicked my legs and clawed at my hand，”said one teacher. “I broke up a fight and was kicked between my legs，”said another. Many people have heard stories like this.  But the situation is more worrying still and it involves parents.

Every child , regardless of the circumstances into which they are born，has the right to achieve their potential，regardless of their parents’ wealth and class.  And we recognize that, as a nation，it is a long way to achieve this goal.But rights come with responsibilities and what worries people is that we are in danger of neglecting the latter.

Far too many children are behaving badly at school，even to the point of being violent to staff. This is terrible enough，but it is hard to be surprised since many children are just mirroring the behavior of their parents. Too many are starting school unable to hold a knife and fork, unused to eating at a table，and unable to use the lavatory properly.  

We are in danger of becoming a nation of families living separate lives under one roof. The bedroom, once a place to sleep，has become the living space for the young. Spending hours in front of computer screens, on social networking sites or being immersed in computer games, children and young people spend little time with their parents. Parents are unable to monitor just what their children are watching.         

Schools cannot right the wrongs of society and teachers cannot become substitute parents. Both parties need to work together. Parents must be helped and given confidence to take back control. They are responsible for setting boundaries for their children’s behavior and sticking to those boundaries when the going gets tough. They are responsible for setting a good example to their children and for devoting that most precious of resources—time—so that children come to school ready and are willing to learn.

阅读下列材料并回答问题

材料一：

人是万物的尺度，是存在的事物存在的尺度，也是不存在的事物不存在的尺度。――普罗泰戈拉

材料二：

人是一件多么了不起的杰作!多么高贵的理性!多么伟大的力量!多么优美的仪表!多么文雅的举动!在行动上多么像一个天使!在智慧上多么像一个天神!宇宙的精华，万物的灵长!――莎士比亚《哈姆雷特》中主公哈姆雷特的一段独白

材料三：

马丁·路德提出“因信称义”说。他认为，灵魂得救只须靠个人虔诚的信仰，根本不需要教会的繁琐仪式。上帝的恩典上是帝给人的礼物，只有上帝才能赦免罪人。信徒得不救不靠行为，全凭信仰。要得救上天堂，不靠教会或行善，更不靠赎罪券。――《路德选集》

材料四：

人生下来就是自由的，人可以说是自由的动物。那么，人民的自由虽可由法律加以保护，但它原是天所赐予的，为任何人所必不可少。如果有人不取这天所赐予的自由，那是对天犯了大罪，对自己又是莫大的耻辱。

――卢梭《社会契约论》

材料一中普罗泰戈拉的观点有何积极意义？
