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?

区分宾语从句、定于从句和状语从句宾语从句和状语从句，都叫做主从复合句。宾语从句主要是中考必考的，是初中阶段必掌握的从句，宾语从句主要是掌握三要素，所谓宾语从句，就是宾语在主从复合句当中充当宾语的一个句子，叫做宾语从句。主句的谓语动词是及物动词，后面如果是词或者是短语的话，是简单句，如果是句子的话，肯定是宾语从句。I know that he good at English.就是宾语从句，三要素，一要素是要注意连词，连词一共学了三类连词，一类连词是that口语当中可以省略，就像刚才说的那一句，I hear he is good at English.还有疑问代词、疑问副词，how where when，疑问代词、疑问副词。还有一类连词weather是否的意思，不是状语从句当中的如果，这一定要和如果区分开，这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序，要用陈述举语序。比如说你家有几口人，我们都说How many people are there in you family?但是这是简单句，一旦说成宾语从句，你可以告诉我你家有几口人吗？Could you tell me how many people there are in you family ?

部编版语文八年级上册《一着惊海天——目击我国航母舰载战斗机首架次成功着舰》教案
2．为了表现出我国航母舰载战斗机首架次成功着舰时惊心动魄的气势，表现出舰载机成功着舰后国人的喜悦，作者在语言上也下了一番功夫，请你结合课文做具体分析。明确：(1)运用修辞手法，描绘着舰场面。“声如千骑疾，气卷万山来。”运用对偶、夸张和比喻的修辞手法，增强文章气势，生动形象地表现了舰载机着舰时的浩大声势，具有感染力。(2)运用细节描写，生动形象地描绘出舰载机着舰的情形。如“震耳欲聋”“轰鸣”描绘出舰载机着舰时巨大的声音，“眨眼之间”“刹那间”“疾如闪电”等词描绘出舰载机着舰时的震撼场面。“牢牢地”“稳稳地”生动地写出了我国舰载机着舰技术的成熟和飞行员操作技能的娴熟。“定格了一个象征胜利的巨大‘V’字”的特写镜头，既是对当时情景的生动再现，也表现了作者对我国航母舰载战斗机首架次成功着舰的喜悦和自豪。
部编版语文七年级上册《春》说课稿
一、说教材1、教材的地位及作用：《春》是人教版语文七年级上册第一单元的第一篇课文，是一篇诗意盎然的写景抒情散文。朱自清先生抓住春天的主要特征，用诗的笔调，描绘了春回大地、万物复苏、生机勃发的景象。抒写出热爱春天、憧憬未来的欣喜之情。本单元重视课文的朗读，激发学生的想象，让学生领略景物之美的同时，感受到语言文字的魅力。2、教学目标知识与能力目标 感知文章内容，欣赏作品语言，学习本文抓住特征描写景物以及寓景于情的写作方法。过程与方法目标引导学生学会细致观察，养成自主、合作、探究的学习方式。情感态度与价值观目标培养学生热爱自然，热爱生活，积极进取的生活态度。3、教学重点与难点 ①教学重点：学习作者抓住事物特点，用鲜明、准确、生动的语言和多种修辞手法具体细致写景状物的方法②教学难点：体悟细致的景物描写与作者细腻的思想感情的巧妙融合
部编版语文七年级上册《猫》说课稿
一、说教材《猫》选自《郑振铎文集》，是人教版初中语文七年级下册第五单元的教学内容。本单元收录的五篇课文都是描写动物的佳作。本课更是通过描写与人类最亲近的动物之一——猫，来启示大家动物是人类的生存伙伴，它们和人类是平等的，正是有了它们，才使我们的世界丰富多彩、生趣盎然。因此，这些可爱的小生灵们值得我们用心去珍惜和呵护的。基于对教材的认识，根据新课程标准的要求。我指定了以下教学目标：1.自读课文，分别概括三只猫的不同来历、外形、性情、在家中的地位、结局以及对我的影响。2.跳读课文，通过作者对第三只猫的亡失而产生的心里感受与前两只猫进行对比，说出文章主旨以及你得到的启示。《猫》这篇文章描写了“我”三次的养猫经历，曲折的表达出同情、怜爱弱小者的思想感情，并从中告诉读者：凡事不可主观臆断，妄下结论，否则就难免出错，甚至造成无法弥补的悔恨。因此，我将教学目标的第一点：概括三只猫的不同来历、外形、性情、在家中的地位、结局以及对我的影响作为本课的教学重点。而说出文章主旨以及得到的启示作为本课教学难点。
部编版语文七年级上册《咏雪》说课稿
学生情况对于初一的学生来说阅历浅，很难独自完成本课的知识学习，而且互相合作能力较差，主要是以自己的兴趣来学习的。所以我准备了以下的教法和学法。（二）说教法1、情景导入 教学为学生创设了良好的环境，使学生能迅速进入角色。2、朗读教学所谓'读书百遍，其义自见'通过朗读，培养了学生良好的朗读习惯和朗读文言文的语感。3、现场演示法可以更形象的体会优美的句子4、激励创新讲述，发展思维。通过这一环节的迁移训练，不但提高了学生的思维能力，而且拓展了学生的思维空间和想象能力。练习的设计能照顾到全体学生，体现层次性。5、淡化教师角色，体现学生主体地位。这堂课教师是作为一个协作者，对学生进行必要的指导，大部分时间都能体现学生参与学习的过程，学生是课堂的主体。（三） 说学法本人更注重师生之间的互动和学生与学生之间的互动，通过自问自答、自问他答或老师解答等形式，充分调动了学生学习的积极性。
（说课稿）《枫树上的喜鹊》部编人教版二年级上册语文
二、说教学目标1.认识“渡、荫”等9个生字，会写“伞、姨”等8个生字。 2.默读课文，根据情境展开合理想象，并把想象的内容写下来。? 3.正确流利地朗读课文，有感情地朗读重点句子，感受作者对喜鹊的喜爱之情。三、说教学重难点1.识记生字，朗读课文，根据情境展开合理想象，并把想象的内容写下来。（重点） 2.感受“我”对枫树和喜鹊的喜爱，感受故事的童趣。（难点）四、说教法和学法1.创设情境法主要是通过创设情境，让学生进入情境中，激发学生的内在情感，为学生进行想象找到共鸣点和切入点。? 2.阅读法我采用朗读、默读。教师范读，表演读，分角色读等引导学生感受作者对喜鹊的喜爱之情。3.练习设计法《语文课程标准》中指出'语文课程是一门学习语言文字运用的综合性、实践性课程',充分说明了语文练习的重要性。练习有助于学生形成熟练的技能和发展学生的思维能力。因此,设计语言训练的练习,是在培养学生的应用意识、实践能力。新课程标准倡导'自主、合作、探究'的学习方式，于是我将'学习的主动权还给学生'。通过自主朗读、小组合作交流、讨论探究等方式开展。
（说课稿）《沙滩上的童话》部编人教版二年级上册语文
一、说教材《沙滩上的童话》是统编语文小学二年级下册第四单元的一篇课文。这是一个非常感人的故事，课文比较具有童趣，与孩子的生活相贴近，符合孩子的年龄特点。 作者用诗一般的语言讲述了一群孩子在沙滩上垒起一座城堡，然后展开想象的翅膀编织了一个美丽的童话：城堡里住着一个凶恶的魔王，抢走了美丽的公主……最后，这群孩子成为攻打城堡的勇士，他们炸死了魔王，救出了公主。故事一方面展现了孩子们快乐缤纷的童年生活，另一方面也歌颂了一种人间的善良温情与正义。在孩子们的童话中，那对生活的热爱之情，那纯真地对他人的关爱和帮助，尽显人性之美。二、说学情二年级下学期，学生已经具备了一定的学习字词的能力和自主阅读的能力。这篇课文的词语比较浅显，可以让学生在阅读中自己积累。对于生字的教学，我重点讲述容易混淆的生字，同时，这样也可以从现在开始培养学生养成良好的预习及阅读习惯。 但学生由于年龄小，注意力不够集中，所以更喜欢情节性较强的故事，需要教师引导在故事中体验情感。
