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.
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).
活动准备: 提供三种颜色不同的瓶盖个三个,每人一套1—4的数字卡片。活动过程:1、 分别取三种颜色不同的瓶盖个三个,一一对应排成三横排,中间一排的瓶盖不动,让三排瓶盖变得一排比一排多一个,讨论如何才能做到。2、 找出相应的数字卡片摆在瓶盖的左边,讨论:比3少1的数是几,应排在哪里;比3多1的数是几,应该排在哪里。
各位老师、各位同学:早上好,我今天讲的题目:《让文明礼仪之花在我们校园处处盛开》。首先,我们来看在校园内出现的几个令人欣喜的现象:早晨,总看见同学们背着书包走进校园,抓紧时间认真地进行早读。还有不少值日的同学,在老师的带领下,打扫班级卫生;或在绿化包干区捡拾落叶和纸屑。三(6)班、三(7)班的一些同学,每天认真地擦着玻璃窗,他们班的玻璃窗总是最亮的。中午,同学们排着整齐的队伍,有的去食堂用餐,有的回家或由家长送饭。食堂用餐的学生用完餐后整理好餐具,翻好凳子,然后走出食堂,决不把没吃完的鸡腿之类的食物带出食堂;而回家吃饭或送饭到校的学生,也按照学校的要求,拿了饭菜在教室里用餐,吃完后再把餐具拿给家长带回家。傍晚放学了,同学们在老师的带领下,排好队伍,带着一天学习的收获,由家长接回家。事实上,良好的行为习惯,是我们顺利学习的前提,也是树立健康人格的基础。著名学者梁启超曾说过,少年智则国智,少年强则国强。我们是祖国的花朵,我们是祖国的未来。如果我们养成了文明的行为习惯,学习环境就一定是良好的、有序的。
