北师大初中九年级数学下册二次函数y=ax2bxc的图象与性质2教案

  • 人教版新目标初中英语八年级下册It’s a nice day, isn’t it教案2篇

    "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。)
