蔡元定①八岁能诗,及长,登泰山绝顶。日惟啖②荠③。于书无不读,朱熹扣④其学,大惊曰:“此吾老友也,不当在弟子列。”
行路难李白金樽清酒斗十千,玉盘珍羞直万钱。停杯投箸不能食,拔剑四顾心茫然。被渡黄河冰塞川,将登太行雪满山。闲来垂钓碧溪上,忽复乘舟梦日边,行路难!行路难!多歧路,今安在?长风破浪会有时,直挂云帆济沧海。

As a boy, Kevin visited national parks and helearned the Earth is in ___12___ condition. He felt worried, and hewanted to ___13___ the Earth. In 2009, he went to swim in water nearNorth Pole(北极)todraw people’s attention to the melting glaciers(融化的冰川).
Long ago, a poor old couple lived on the coast.One day, an old storyteller came to their village. The old couple gave him ameal. In return, he gave them a coffee mill (磨粉机)and said, “Say, ‘Mill, please grind (磨粉)’,”

Antarctica lies in the most southern part of theworld. It is the coldest area on Earth. There isn’t much rain, but there is alot of snow and wind. The lowest temperature was on 21 July in 1983 at -89.2℃!
During 1907-1909, British explorer EarnestShackleton explored Antarctica on foot. In 1911, two explorers—a British mannamed Scott and a Norwegian named Amundsen—raced 1, 400 kilometres to the SouthPole (南极).Amundsen arrived first.
Taiping nijiaojiao is made of the mudfrom the local mountain. It takes more than ten steps to make the clay toy, andthe key step is to knead (捏) it with your hands. You can knead the clay toyinto anything, like animals and plants. The blowhole is the most difficult partto make, for the size of the blowhole makes a difference to the sound. Whilecoloring, you can use traditional cultural elements (元素) thatcarry good meanings. It’s hard to make taipingnijiaojiao. But when you finally make it, you will feel proud of yourself.
“Red Trip” in TonghuaTonghua is a good choice to have a “red trip”. It is aplace full of “red stories”. The well-known national hero Yang Jingyu oncefought here. Experience the “red spirit”!
I joineda band (乐队)as a drummer in my middle school. I thought itwould be fun playing the drum and meeting new friends. At first it was easy,but a month later, it got difficult. I was the only one who couldn’t keep pace (节奏)with the other players. Our teacher,Angie, singled me out to keep practicing while everyone else got to relax. Ifelt ashamed (羞愧的)as my teammates watched me fail so many times.Finally I got so tired of practicing that I didn’t care about doing it right.
When itcomes to a meaningful life, we might think of love, happiness and health. Alife filled with meaning is what most of us want for ourselves. Then, whatmakes a meaningful life?Manyresearchers agree that a meaningful life comes down to three factors (因素): havinglong-term goals, believing that one’s life matters, and feeling that one’s lifefits together and “makes sense”.But we believe there is more to consider. Sometimeslife enables us to experience small moments of beauty. When people are open toappreciating (欣赏) suchexperiences, these moments may improve how they see their own life. We callthis experiential appreciation (EA).
(一)观图激趣、设疑导入 1.出示课件-情境图师:上节课我们初步学习了里程表的知识,这节课我们接着来研究里程表中的数学问题。板书课题:里程表(二)师:淘气的叔叔是出租车司机。淘气为了记录叔叔每天跑的路程,淘气在叔叔星期一早上出车时,里程表的读数是35千米。淘气记录了叔叔周一至周五每天回家时的里程表读数。(课件展示里程表)。(二)探究新知1.例1(1)师:请同学们认真观看淘气记录的叔叔的周一到周五的里程表,想一想,说一说你知道了哪些数学信息?生:我发现了叔叔周一行了160千米。 师:同学们他说找到数学信息对吗?生:160千米不是星期一的行驶里程,应该是星期一晚上里程表上的读数。 星期二里程表上的读数是350,。生:。。。。师:同学们找的数学信息非常多,非常全面。(2)小组讨论交流:淘气根据题意画了一个图,你看懂了吗?与同伴说一说。
由于题目较简单,所以学生分析解答时很有信心,且正确率也比较高,同时也进一步体会到了借助“线段图”分析行程问题的优越性.六、归纳总结:活动内容:学生归纳总结本节课所学知识:1.会借线段图分析行程问题.2.各种行程问题中的规律及等量关系.同向追及问题:①同时不同地——甲路程+路程差=乙路程; 甲时间=乙时间.②同地不同时——甲时间+时间差=乙时间; 甲路程=乙路程.相向的相遇问题:甲路程+乙路程=总路程; 甲时间=乙时间.目的:强调本课的重点内容是要学会借线段图来分析行程问题,并能掌握各种行程问题中的规律及等量关系.引导学生自己对所学知识和思想方法进行归纳和总结,从而形成自己对数学知识的理解和解决问题的方法策略.
解:(1)设x分钟后两人第一次相遇,由题意,得360x-240x=400.解得x=103.(103×360+103×240)÷400=5(圈).答:两人一共跑了5圈.(2)设x分钟后两人第一次相遇,由题意,得360x+240x=400.解得x=23(分钟)=40(秒).答:40秒后两人第一次相遇.方法总结:环形问题中的相等关系:两个人同地背向而行:相遇问题(首次相遇),甲的行程+乙的行程=一圈周长;两个人同地同向而行:追及问题(首次追上),甲的行程-乙的行程=一圈周长.三、板书设计追赶小明→行程问题→相遇问题追及问题环形问题教学过程中,通过对开放性问题的探讨与交流,体验生活中数学的应用与价值,感受数学与人类生活的密切联系,激发学生学习数学的兴趣,培养学生的创新意识、团队精神和克服困难的勇气.
亲爱的孩子,高中生活,特别是冲刺阶段,是一个极其艰辛的过程,在一次次考试的历练中,在亮到深夜的台灯下,在你们疲惫、失落的眼神里,爸爸、妈妈真切地感受着你们的艰辛和坚韧。也许我们曾经的担心、焦虑、唠叨给你们添加了压力,但这就是父母啊,一切都是为了孩子!其实,父母因为有你们这样出色的孩子已经深感自豪。孩子们,金榜题名固然重要,但在高中阶段所收获的那一份刻骨铭心的历练、学会驾驭人生、学会坚韧、学生拼搏的素养,这些都将成为我们终生受用的宝贵财富。如果对高考有这样的理解,这样的把握,我相信无论你们在怎样的状况下,都会义无反顾,信心百倍,马到成功。希望你们能坚守“最初的梦想”,练就“隐形的翅膀”;坚定信心,坚忍不拔,毕竟天道酬勤,不必创造奇迹,但求无愧于心!
