学习型研究（道路反光镜的实际应用）求研究过程和结论（最好写出如何做的过程和一些概括性的结论）

D

A中“不足10%左右”说法不合理；B中句式杂糅；C中“橡皮擦、无刺鼻气味的涂改液和学习用品。”说法不合理。

解题思路：小球先自由落体运动，后做圆周运动，最后最平抛运动，利用动能定理和平抛运动规律联立即可求解．

乙同学的解答没问题，但甲同学的命制试题有问题
小球从下落到P点的过程中，根据机械能守恒定律得mgh＝
1
2mv2+mgR ①
从P点平抛，根据平抛运动规律得：

R＝vt
R＝
1
2gt2 ②
①②联立得：h＝
5
4R
v＝

gR
2＜
gR所以不可能通过最高点P，所以甲同学的命制试题有问题
答：乙同学的解答没问题，但甲同学的命制试题有问题

点评：
本题考点： 机械能守恒定律；牛顿第二定律；向心力．

考点点评： 对于竖直面的圆周运动有两种模型；杆模型和绳模型，对于绳模型一定要注意恰好过最高点的条件是只有重力提供向心力，v0＝gR，要通过最高点应v≥gR．

① 15名与会者 ② 在"建设"后加"作贡献" ③ 改为"说话做事前" ④ 改"提高"为"加强" ⑤ 改为"不重视这一点" ⑥ 改分号为逗号 ⑦ 改为"不尽如人意"
〔简析〕①"与会者"就是"参加会的人",故"到会的"与"与会者"重复了.②"为社会主义精神文明建设"这一介宾短语之后缺少成分.③介词"当"和"在"不可乱用.如可说:"在一九九八年",而不可说"当一九九八年".可说:"在……以前",而不可说"当……以前".④"提高"与"意识"间不搭配.⑤"重视"一词可带宾语,但不可带形容词补语,因此,"重视好"是不合语法的.⑥在使用分号的"前"与"后"一般应使用逗号.所以⑥处的分号如果要保留,那么⑥⑦两处的标点应如下安排:……对有利于精神文明建设的事,应该大力提倡;对不尽如人意的地方,应该注意改进.⑦"不尽如人意"是说:不全都顺合人的心意,与"不尽"一词所使用的范围不同.

　　①“学习型社会”概念是谁最早提出来的?
　　学习型社会的由来
　　提出
　　学习化社会是美国学者罗伯特·哈钦斯于1968年首次提出的.联合国教科文组织国际教育发展委员会编著、被誉为当代教育思想发展中里程碑的著名报告《学会生存》,特别强调终身教育和学习化社会两个概念,把学习化社会作为未来社会形态的构想和追求目标.从此,终身教育和学习化社会的理念就在国际社会迅速传播开来,成为许多国家、地区、社会团体推进和实施教育改革和发展的指导原则,成为社会发展和社会进步追求的一个重要目标.
　　②“学习型社会”的内涵是什么?
　　所谓学习型社会,就是有相应的机制和手段促进和保障全民学习和终身学习的社会,其基本特征是善于不断学习,形成全民学习、终身学习、积极向上的社会风气.其核心内涵是全民学习、终生学习.就像是坐标上的两个数轴,全民学习、终身学习,从两个维度标示了人们的学习与其生存、发展的关系.学习型社会是时代发展和社会进步的产物,它对学习的要求比以往任何时候都更强烈、更持久、更全面,全社会的人只有不断地学习,才能应对新的挑战.学习型社会不是自然而然地形成的,需要人们根据实践发展的要求,努力建设学习型家庭、学习型组织、学习型企业、学习型社区和学习型城市等等.学习型社会是20世纪60年代由美国学者哈钦斯首先提出的.20世纪70年代,联合国教科文组织提出：人类要向着学习化社会前进.此后,许多国家相继开展了学习型社会创建活动.
　　③我国提出建设“学习型社会”
　　从我国的基本国情和现实需要出发,提出学习型社会这个具有时代特征的重大课题,是实现社会主义现代化建设新三步走的宏伟目标和战略步骤的重大举措.在教育研究中,我国许多学者早先也多使用学习化社会的概念,近年来,国家领导人高度关注这个问题.2001年5月江泽民在亚太经合组织人力资源能力建设高峰会议上的讲话明确指出：“构筑终身教育体系,创建学习型社会.”笔者以为,学习化社会和学习型社会方向、本质一致,是同一个社会形态或社会阶段两个不同的层次或水平.“化”者彻头彻尾彻里彻外之谓也,表示彻底通透之意；“型”者形状、形态、框架、格局之谓也,表示基本总体之意.笔者认为,从我国的国情出发,提出学习型社会的目标构想似更为实事求是、切实可行.当然,学习化社会始终仍然是教育（乃至社会）改革发展的理想境界和目标追求.

以学习为促发展!以学习为理念,可以报销丰富自己,也可以报效国家!

Lifelong learning (终身学习)
In the past ,when students graduated from college and get jobs,only some of them went on with their study. But today, lifelong learning in becoming more and more common(常见的)
Lucy,who is forty, teaches physics at acollege in Boston.”Next term,I’ll teach some of my classes by usi8ng the Internet.This is the way of teaching that I’ve never used bdfore,””These days, I am taking a class to learn how to teach in this way. If not, I will lose my job.” At the same time, Lucy’s seventy-year-old parents, who live in New York, are taking an art history class on line” We love this subject,” says her father ,”and we learn it to enjoy ourselves. You see we can study with people all over the world. What fun it is to learn like this!”
Happiness is for everyone. In fact , happiness is always around you if you put your heart into it .When you are in trouble at school, your friends will help you ; when you study hard at your lessons, your parents are always tkeing good care of your life and your health; when you get success, your friends will congratulate you ; When you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy , too. All these are your happiness. If you notice a bit of them you can find that happiness is always around you .
Happiness is not the same as money , it’s a feeling of your heart. When you are poor, you can also be very happy , because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are happy, because you have more chances to challenge yourself . So you cannot always say you are poor and you have bad luck. If you take every chance you get, you can be a happy and lucky person.
