《中小学生守则》自2004年发布以来，对中小学生良好行为习惯的养成以及学校形成良好的校风、学风、教风等都起了重要作用。随着中小学生成长环境的变化，及其身心发展呈现新的特点，关乎人才培养的中小学生行为守则也应及时修订，以更好适应现代教育规律。

2012年，教育部启动了修订《中小学生守则》的程序，历经基层调研、国际比较、多方参与、反复论证、集思广益的过程，形成最大公约数、凝聚了广泛共识，于2015年8月27日印发了新修订的《中小学生守则》。《守则》共9条，282字，涵盖学生德智体美劳全面发展的基本要求，保留了2004年守则中仍具时代价值、体现中华传统美德、应长期坚持的内容，如热爱祖国、热爱人民等；补充了一些更具操作性、学生可以做到的具体行为规范内容，如主动分担家务、自觉礼让排队等；增加了新时期学生成长发展中学校、社会和家庭高度关注的内容，如养成阅读习惯、低碳环保生活等。新版《中小学生守则》既 “高大上”，又“接地气”，新增内容与时俱进，时代特色鲜明。

结合材料，运用价值观的知识，分析新版守则既“高大上”，又“接地气”的意义。

如图，M、N、P、R分别是数轴上四个整数所对应的点，其中有一点是原点，并且MN=NP=PR=1．数a对应的点在M与N之间，数b对应的点在P与R之间，若数a的对应点与数b的对应点之间相距2个单位长度，则原点是(    )

    Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.
    Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.
    Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket. At first, Dr. Naismith wanted to throw the ball into a box. As he could not find boxes of the right size, he had to use fruit baskets instead. That is how the game got its name.

材料一  沈括（1031 -1095）字存中，钱塘（夸浙江杭州）人，是中国古代最伟大的科技思想家之一。《宋史》卷331《沈括传》说他“博学善文，于天文、方志、律历、音乐、医药、卜算无所不通，皆有所论著”，嘉祐八年（1063），沈括登进士第。熙宁二年（1069）二月，洗括因支持变法而被任命为删定三司条例官。熙宁六年（1073）奉诏提举司天监，从此开始了他投身于振兴宋代科技事业的人生历程。晚年退隐润州梦溪因而著《梦溪笔谈》一书

材料二  为了确定极星的位置，他（沈括）曾连续三个月进行测量，才得到极星离开北极三度有余的结论；为了验证“虹能入溪涧饮水”的问题，曾“与同职扣涧观之”，井进而发现“自西望东则见，立润之东西望，则为日所铄，都无所睹”。，此外如关于凹、凸面镜的成像特点的认识，关于指南针装置方式的认识，关于月亮盈亏现象的认识等等，都是通过实验得到的。一…对于所观察到的现象和问题，经反复思索，研究后仍无法解决的，他就只是如实记录，井说明不知其中道理的症站所在，而决不故弄玄虚，妄下断语。例如，在记述磁针有指南、也有指北的现象后，说“理应有异，来深考耳”。
