    "Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

    初中国旗下的讲话稿大全

    国旗下讲话是对学生进行思想道德教育的重要载体。与其他德育形式相比,对于培养师生爱国情感、帮助学生树立远大理想、促进良好校风的形成,传播正能量,国旗下讲话有其不可替代的价值。本文是小编为大家整理的初中国旗下讲话稿,仅供参考。初中国旗下讲话稿篇一:尊敬的各位老师、亲爱的同学们:大家好!今天我演讲的题目是《安全常系心中》。你们知道生活中什么最重要吗?是安全。只有保证我们生命和生活的安全,一切才有意义。当同学们听到有关小学生意外伤害事故时,不知道你们想了些什么。我想,同学们至少会想到:这些教训无论发生在谁的身上都会给受害者人身造成伤害、甚至死亡;会给受害者家庭造成极大的损失;会给学校正常教学秩序造成混乱;会给社会造成不稳定影响。安全问题关系到我们每一位学生的切身利益,只有安全才能为我们保驾护航。在这里,我向全体同学发出倡议:1、校内课间不追逐打闹,上下楼梯慢步轻声,靠右行。2、放学按时离校,不在校园内逗留。3、不到小摊小贩购买食物,不吃不洁食物,喝水要讲究卫生,注意身体健康。4、保证用电安全,不乱动电源插座。

    人教版新课标小学数学五年级下册假分数化成整数或带分数说课稿2篇

    一、说教材(一)教材简析《假分数化成整数或带分数》是小学数学五年级(下册)第六单元中的内容。本节内容安排了两个例题。这部分内容是在学生掌握了假分数的意义后,进一步学习把假分数化成整数或带分数,有利于以后进行分数计算打下坚实的基础。(二)教学目标根据教材编排特点,我确定以下教学目标:1、知道带分数是假分数,是整数与真分数合成的数。2、会把假分数化成整数或带分数。3、使学生经历假分数化成整数或带分数的探索过程,进一步发展数感。4、培养良好的学习习惯,树立学好数学的信心。(三)教学重、难点会把假分数化成整数或带分数。二、说教法、学法通过这一环节的教学,把假分数化成整数或带分数时,先要让学生根据假分数的含义进行思考。在这个基础上,再启发学生根据分数与除法的关系计算出结果,并把用不同方法求得的结果进行比较,认识到每种方法都是有道理的。
