人教部編版語文八年級上冊三峽教案
此外，多種形式的朗讀，為學生在朗讀中理解字詞、內容、情感打下了基礎。素養(yǎng)提升《三峽》中的修辭手法1.并提為了使句子緊湊、文筆簡練，古人常用并提法行文，把本來應該寫成兩個短語或兩個句子的話，合并為形式上的一個短語或一個句子，把相同的語句成分放在一起并提，但表意上仍然必須按照兩個短語或句子的組合關系來分別相承，這種修辭手法就叫并提。這種句子翻譯時應分為兩句。如：（1）“自非亭午夜分，不見曦月?！薄巴の纭薄耙狗帧笔莾蓚€不并存的時間，“曦”和“月”是兩種不同的自然現(xiàn)象，合起來是講不通的，這句話應理解為“自非亭午，不見曦；自非夜分，不見月”（如果不是在正午，就看不到太陽；如果不是在半夜，就看不到月亮）。（2）“素湍綠潭，回清倒影。”這句和上句一樣，應理解為“素湍回清，綠潭倒影”（白色的急流中有回旋的清波，綠色的潭水中有倒映著的各種景物的影子）。
人教部編版語文八年級上冊詩詞五首教案
設問2：下片主要寫了什么內容？預設 回答天帝。下片緊承上片的天帝詢問，作出回答。我報路長嗟日暮，學詩謾有驚人句。（這是詞人回告天帝。一個“嗟”字，生動地傳達出作者對日暮途遠的嘆息，感慨空有才華，于世事無補。）九萬里風鵬正舉。風休住，蓬舟吹取三山去！（回答天帝，希望自己像大鵬一樣高飛遠走，到海上仙山去。傳達出詞人對現(xiàn)實的厭棄和對美好境界的追求。）設問3：本詞和《赤壁》都表現(xiàn)了作者對自身才華、命運的認識，但又有什么不同？預設 杜牧借對三國史事的遐想，慨嘆歷史上英雄成名的際遇，曲折表達自己空有抱負，生不逢時、無從施展的無奈；本詞是借夢境與天帝對話，表達對自己空有一身文學才華卻屢遭戰(zhàn)亂，甚至連個人的安定幸福都無法保障的不滿。【設計意圖】本環(huán)節(jié)旨在品讀《漁家傲》，引導學生通過品讀詞句，感知詞作內容，理解詞人情感，并通過鑒賞藝術手法，提高審美能力。
人教部編版語文八年級上冊中國石拱橋教案
中國的拱橋的歷史可追溯到東漢時期，至今已有一千八百多年。中國的拱橋別具一格，造型優(yōu)美，曲線圓潤，形式多樣，世界罕見。拱橋按照建筑材料分為石拱橋、磚拱橋和木拱橋，其中較為常見的是石拱橋。拱橋又分為單拱、雙拱、多拱，拱的多少根據(jù)河面的寬度而定。多拱橋一般正中間的拱較大，兩邊的拱略小。根據(jù)拱的形狀，又分五邊、半圓、尖拱、坦拱。橋面上鋪板，橋邊有欄桿。單孔拱橋的拱形呈拋物線的形狀，如北京頤和園的漢白玉石橋玉帶橋。多孔拱橋適于跨度較大的寬廣水面，常見的多為三、五、七孔，以奇數(shù)為多，偶數(shù)較少。當多孔拱橋某個孔的主拱受荷時，能通過橋墩的變形或拱上結構的作用把荷載由近及遠地傳遞到其他孔主拱上去，這樣的拱橋稱為連續(xù)拱橋，簡稱“聯(lián)拱”。如建于唐代元和年間的古橋蘇州寶帶橋，橋下共有53個孔相連，橋孔之多，結構之精巧，為中外建橋史上所罕見。
利用計算器進行有理數(shù)的計算教案教學設計
計算器的面板是由鍵盤和顯示器組成的。顯示器是用來顯示輸入的數(shù)據(jù)和計算結果的裝置。顯示器因計算器的種類不同而不同，有單行顯示的，也有雙行顯示的。在鍵盤的每個鍵上，都標明了這個鍵的功能。我們看鍵盤上標有的鍵，是開機鍵，在開始使用計算器時先要按一下這個鍵，以接通電源，計算器的電源一般用5號電池或鈕扣電池。再看鍵，是關機鍵，停止使用計算器時要按一下這個鍵，來切斷計算器的電源，是清除鍵，按一下這個鍵，計算器就清除當前顯示的數(shù)與符號。的功能是完成運算或執(zhí)行命令。是運算鍵，按一下這個鍵，計算器就執(zhí)行加法運算。
平行線的性質定理和判定定理教案教學設計
1、互逆命題：在兩個命題中，如果第一個命題的條件是第二個命題的 ，而第一個命題的結論是第二個命題的 ，那么這兩個命題互逆命題，如果把其中一個命題叫做原命題，那么另一個命題叫做它的 .2、互逆定理：如果一個定理的逆命題也是 ，那么這個逆命題就是原來定理的逆定理.注意(1)：逆命題、互逆命題不一定是真命題，但逆定理、互逆定理，一定是真命題.(2)：不是所有的定理都有逆定理.自主學習診斷：如圖所示：(1)若∠A= ，則AC∥ED，( ).(2)若∠EDB= ，則AC∥ED，( ).(3)若∠A+ =1800，則AB∥FD，( ).(4)若∠A+ =1800，則AC∥ED，( ).

大班數(shù)學活動設計：趣味接龍課件教案
重點：了解接龍游戲的規(guī)律，并能運用比較、對應的經(jīng)驗合作制作接龍卡。難點：1.孩子對前后卡片的界限區(qū)分。成因是接龍卡本身有兩小部分所組成，容易會造成孩子辨別卡片上的混淆。2.操作中的前后推理。成因是由于幼兒的逆向思維發(fā)展尚不成熟，容易被附近一個已知數(shù)所誤導。解決策略：1.逐步化解法：借助雙色的卡片做教具，以層層遞進的方式從順向推理向逆向推理逐步過渡。2．資源共享法：以小組合作形式開展操作活動，能以兵兵互教的形式化解補缺的難點，達到資源共享。活動目標：1.了解接龍游戲的規(guī)律，并能運用比較、對應的經(jīng)驗合作制作接龍卡。 2.嘗試用簡潔語言介紹和交流自己的操作結果，能運用以往的數(shù)學經(jīng)驗表明意思。

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
