人教部编版语文八年级上册三峡教案
此外，多种形式的朗读，为学生在朗读中理解字词、内容、情感打下了基础。素养提升《三峡》中的修辞手法1.并提为了使句子紧凑、文笔简练，古人常用并提法行文，把本来应该写成两个短语或两个句子的话，合并为形式上的一个短语或一个句子，把相同的语句成分放在一起并提，但表意上仍然必须按照两个短语或句子的组合关系来分别相承，这种修辞手法就叫并提。这种句子翻译时应分为两句。如：（1）“自非亭午夜分，不见曦月。”“亭午”“夜分”是两个不并存的时间，“曦”和“月”是两种不同的自然现象，合起来是讲不通的，这句话应理解为“自非亭午，不见曦；自非夜分，不见月”（如果不是在正午，就看不到太阳；如果不是在半夜，就看不到月亮）。（2）“素湍绿潭，回清倒影。”这句和上句一样，应理解为“素湍回清，绿潭倒影”（白色的急流中有回旋的清波，绿色的潭水中有倒映着的各种景物的影子）。
人教部编版语文八年级上册诗词五首教案
设问2：下片主要写了什么内容？预设 回答天帝。下片紧承上片的天帝询问，作出回答。我报路长嗟日暮，学诗谩有惊人句。（这是词人回告天帝。一个“嗟”字，生动地传达出作者对日暮途远的叹息，感慨空有才华，于世事无补。）九万里风鹏正举。风休住，蓬舟吹取三山去！（回答天帝，希望自己像大鹏一样高飞远走，到海上仙山去。传达出词人对现实的厌弃和对美好境界的追求。）设问3：本词和《赤壁》都表现了作者对自身才华、命运的认识，但又有什么不同？预设 杜牧借对三国史事的遐想，慨叹历史上英雄成名的际遇，曲折表达自己空有抱负，生不逢时、无从施展的无奈；本词是借梦境与天帝对话，表达对自己空有一身文学才华却屡遭战乱，甚至连个人的安定幸福都无法保障的不满。【设计意图】本环节旨在品读《渔家傲》，引导学生通过品读词句，感知词作内容，理解词人情感，并通过鉴赏艺术手法，提高审美能力。
人教部编版语文八年级上册中国石拱桥教案
中国的拱桥的历史可追溯到东汉时期，至今已有一千八百多年。中国的拱桥别具一格，造型优美，曲线圆润，形式多样，世界罕见。拱桥按照建筑材料分为石拱桥、砖拱桥和木拱桥，其中较为常见的是石拱桥。拱桥又分为单拱、双拱、多拱，拱的多少根据河面的宽度而定。多拱桥一般正中间的拱较大，两边的拱略小。根据拱的形状，又分五边、半圆、尖拱、坦拱。桥面上铺板，桥边有栏杆。单孔拱桥的拱形呈抛物线的形状，如北京颐和园的汉白玉石桥玉带桥。多孔拱桥适于跨度较大的宽广水面，常见的多为三、五、七孔，以奇数为多，偶数较少。当多孔拱桥某个孔的主拱受荷时，能通过桥墩的变形或拱上结构的作用把荷载由近及远地传递到其他孔主拱上去，这样的拱桥称为连续拱桥，简称“联拱”。如建于唐代元和年间的古桥苏州宝带桥，桥下共有53个孔相连，桥孔之多，结构之精巧，为中外建桥史上所罕见。
利用计算器进行有理数的计算教案教学设计
计算器的面板是由键盘和显示器组成的。显示器是用来显示输入的数据和计算结果的装置。显示器因计算器的种类不同而不同，有单行显示的，也有双行显示的。在键盘的每个键上，都标明了这个键的功能。我们看键盘上标有的键，是开机键，在开始使用计算器时先要按一下这个键，以接通电源，计算器的电源一般用5号电池或钮扣电池。再看键，是关机键，停止使用计算器时要按一下这个键，来切断计算器的电源，是清除键，按一下这个键，计算器就清除当前显示的数与符号。的功能是完成运算或执行命令。是运算键，按一下这个键，计算器就执行加法运算。
平行线的性质定理和判定定理教案教学设计
1、互逆命题：在两个命题中，如果第一个命题的条件是第二个命题的 ，而第一个命题的结论是第二个命题的 ，那么这两个命题互逆命题，如果把其中一个命题叫做原命题，那么另一个命题叫做它的 .2、互逆定理：如果一个定理的逆命题也是 ，那么这个逆命题就是原来定理的逆定理.注意(1)：逆命题、互逆命题不一定是真命题，但逆定理、互逆定理，一定是真命题.(2)：不是所有的定理都有逆定理.自主学习诊断：如图所示：(1)若∠A= ，则AC∥ED，( ).(2)若∠EDB= ，则AC∥ED，( ).(3)若∠A+ =1800，则AB∥FD，( ).(4)若∠A+ =1800，则AC∥ED，( ).
大班科学教案：常识活动设计：圆形的妙用

大班数学活动设计：趣味接龙课件教案
重点：了解接龙游戏的规律，并能运用比较、对应的经验合作制作接龙卡。难点：1.孩子对前后卡片的界限区分。成因是接龙卡本身有两小部分所组成，容易会造成孩子辨别卡片上的混淆。2.操作中的前后推理。成因是由于幼儿的逆向思维发展尚不成熟，容易被附近一个已知数所误导。解决策略：1.逐步化解法：借助双色的卡片做教具，以层层递进的方式从顺向推理向逆向推理逐步过渡。2．资源共享法：以小组合作形式开展操作活动，能以兵兵互教的形式化解补缺的难点，达到资源共享。活动目标：1.了解接龙游戏的规律，并能运用比较、对应的经验合作制作接龙卡。 2.尝试用简洁语言介绍和交流自己的操作结果，能运用以往的数学经验表明意思。

The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply
