This theme of the part is “ Describe people or things in greater detail”. Students have learned the grammar(restrictive relative clauses) in Book 1, and further review and consolidate its structure “prep+relative pronouns(which/whom)” and the relative adverbs(when, where and why), besides students should understand its form, meaning and functions. In this section, students should be able to express the grammar correctly in daily communication and in the writing. 1. Review the basic usages of relative pronouns and adverbs of attributive clauses . 2. Learn to use some special cases about restrictive relative clauses.3. Learn to write sentences with restrictive relative clauses flexibly according to the context.1. Review the basic usages of relative pronouns and adverbs of attributive clauses .2. Learn to use some special cases about restrictive relative clauses.3. Learn tow rite sentences with restrictive relative clauses flexibly according to the context.Step 1. Observe the following sentences, and mark the relative pronouns and the adverbs. 1. After listening to the scientists who had studied the problems, and citizens who lived near the dam, the government turned to the United Nations for help.2.

What is the head noun ?2. What relative words should be used ?3. What elements do they act in these sentences ?
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本節(jié)語法思考:定語從句在復合句中的作用是什么? 關(guān)系詞有哪些?定語從句在復合句中的作用相當于形容詞,它在句中作定語修飾名詞或代詞。他們在先行詞和定語從句之間起到聯(lián)系作用,同時在意義上代表先行詞并在定語從句中擔任一個成分。被定語從句所修飾的詞稱先行詞,定語從句一般放在先行詞的后面。
Listening and Speaking introduces the topic of “Take part in a youth project”. The listening text is an interview about an international youth cultural heritage protection project. More than 20 high school students from seven countries participated in the project. The reporter interviewed two participants Stephanie and Liu Bin. By listening to the text, students can understand the significance of cultural heritage protection, and teenagers can use their knowledge, combine their own interests and advantages, etc. to participate in the action of cultural heritage protection. Listening and Talking introduces the theme of "Talk about history and culture". The listening text is a dialogue between two tourists and tour guides when they visit the Kremlin, red square and surrounding buildings. The dialogue focuses on the functional items of "starting a conversation", which is used to politely and appropriately attract the attention of the others, so as to smoothly start a conversation or start a new topic. The purpose of this section is to guide students to understand the history and current situation of Chinese and foreign cultural heritage in their own tourism experiences or from other people's tourism experiences, explore the historical and cultural values, and be able to express accurately and appropriately in oral communication.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2.

科學家預測,就地區(qū)而言,位于低緯度的大部分國家,農(nóng)作物的產(chǎn)量將減少;而位于高緯度的國家,農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū),因此,氣候變化的這種區(qū)域差異性,可能會使發(fā)展中國家所面臨的問題更為嚴峻。板書:3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹:全球變暖會影響整個水循環(huán)過程,可能使蒸發(fā)加大,改變區(qū)域降水量和降水分布格局,增加降水極端異常事件的發(fā)生,導致洪澇、干旱災害的頻次和強度增加,以及地表徑流發(fā)生變化。隨著徑流減少,蒸發(fā)增強,全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折:既然全球變暖會引起很多不利影響,那么作為人類應如何面對這一挑戰(zhàn)呢?這就是我們要討論的第三個問題。板書:三、氣候變化的適應對策討論:請大家閱讀結(jié)合教材P53氣候變化的適應對策部分討論人類應如何面對全球變暖這一問題 呢?
The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.

1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運動,則力對物體做功的功率保持不變。此情況下,任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當路面阻力較小時,牽引力也小,速度大,即汽車可以跑得快些;當路面阻力較大,或爬坡時,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時增大,但是這一情況應以二者乘積等于額定功率為限度,即當實際功率大于額定功率以后,這種情況不可能實現(xiàn)。

一:活動背景: 隨著天氣的變冷及幼兒外出活動發(fā)現(xiàn)的落葉,使幼兒對冬天的到來有了初步的感知,對他們來說寒冷的冬天太奇妙、太神奇了,他們想揭開冬天的面紗,他們對冬天渴望探索更多的知識。如:他們會問:為什么樹葉會在冬天落下來、冬天為什么會很冷、冬天為什么會下雪、門窗上為什么有冰花,還有的幼兒說:冬天冷水會結(jié)冰,我們可以滑冰玩、冬天下雪我們可以堆雪人、冬天冷就不會有蚊子不會被蚊子咬了等等。結(jié)合幼兒對冬天所產(chǎn)生的神秘感和已了解的知識內(nèi)容,我們開展了主題活動——冬天的秘密,借此,讓幼兒對冬天有更全面的認識,揭開冬天的秘密。 首先,我們在幼兒中開展調(diào)查,發(fā)現(xiàn)大部分幼兒對冬天的冷都感到可怕,這對他們來說可能對四季交替不夠了解,這需要我們的引導講解,通過調(diào)查我們還發(fā)現(xiàn)幼兒對冬天的萬物變化非常感興趣,特別是:下雪、動物的冬眠,從幼兒的好奇心出發(fā),我們決定以冬天的變化為著眼點,進行主題活動的開展?! 《夯顒拥哪康模骸 ?. 活動中,讓幼兒了解冬天的各種變化、動植物的過冬方式及不同地方的不同過冬方式。 2. 冬天的活動及冬天的節(jié)日,使幼兒對冬天由更進一步的了解,從而對冬天有更深的認識。 三;主題活動網(wǎng)絡圖: 晝長夜短 寒冷 雪花、冰雹 變化 的冬季 冬眠、南遷、躲 天氣 現(xiàn)象 不同地方 儲備食物、冬眠、 圣誕節(jié)、元旦、春節(jié) 冬天的景色 過冬方式 冬天的節(jié)日 冬天的秘密 動物 動物趣聞 冬天的活動 植物人類的變化 衣服的變化 蔬菜、莊稼 跳繩、堆雪人 制作漂亮 樹、花 食物 疾病 取暖 天冷我不怕 踢毽子 的冬裝 常綠樹、落葉樹 預防感冒 樹葉找家 注: 為教師預設內(nèi)容、 師生共同生成、 為幼兒生成
【教學設計】一、教學目的:1、引導學生關(guān)注生活,向生活學習語言。2、了解新詞新語,能正確評價和運用新詞新語。二、教學重難點:1、重點:認識并評價新詞新語。2、難點:如何評價新詞新語三、教學用時:一課時四、教學過程預設(一)導入新課以前如果有人說我可愛,我會很高興:我還是有優(yōu)點的哦?,F(xiàn)在如果有人說我可愛,我就會心里嘀咕了:這是什么意思呀?同學們知道這有什么意思嗎?(可愛=可憐沒人愛)如果大家留心就會發(fā)現(xiàn),類似這樣的詞語很多,在網(wǎng)上是特別流行,很新穎、獨特,誰來列舉幾個?(點評學生所列舉出的詞語)網(wǎng)絡上有新詞新語,其它媒體(如報刊、電視等)都有新詞新語。關(guān)于新詞新語的概念,一般認為,新近創(chuàng)造出來的詞語,或是舊詞新用,這樣的詞語就叫新詞新語。
2、學習有關(guān)政治知識學習政治知識有助于提高辨別是非能力,堅持正確政治方向;有助于緊扣時代脈搏,開闊眼界;有助于樹立國家觀念,維護國家利益;有助于增強民主法制觀念培養(yǎng)公民意識;有助于提高參與政治生活的能力。3、參與政治生活,貴在實踐教師活動:同學們參加過什么政治活動?你還知道有哪些可以參與的政治活動?學生活動:積極思考。我國公民參與政治生活的方式多種多樣,無論什么方式,重要的是參與,在實踐中才能才能不斷提高自己的政治素質(zhì)和參與政治生活的能力。(三)課堂總結(jié)、點評本節(jié)內(nèi)容講述了我國的政治生活的主要內(nèi)容和中學生參與政治生活的方式、途徑,這對我們今后提高自身政治素質(zhì),增強參與政治生活的能力等,證明了奮斗方向。
2.辯證的否定(1)辯證的否定是事物的自我否定。事物內(nèi)部存在著肯定方面和否定方面,它們既對立又統(tǒng)一。最初,肯定方面處于支配地位,否定方面處于被支配地位。在這種情況下,事物就被肯定著。但是,在矛盾雙方的斗爭中,否定方面總會由弱變強。一旦否定方面由被支配地位上升為支配地位,事物就轉(zhuǎn)化到了自己的對立面,實現(xiàn)了對事物的否定。事物最終之所以被否定,根源在于事物的內(nèi)部,是事物內(nèi)部的否定因素戰(zhàn)勝了肯定因素。因此,事物的否定是自我否定。(2)辯證的否定是事物發(fā)展的環(huán)節(jié)和聯(lián)系的環(huán)節(jié)。所謂發(fā)展,是指新事物的產(chǎn)生和舊事物的滅亡。而實現(xiàn)這一過程必須要對舊事物進行否定,否定實現(xiàn)了事物由舊質(zhì)向新質(zhì)的飛躍。新事物在否定舊事物時,并不是把舊事物全盤拋棄,一筆勾銷。舊事物是新事物的母體,新事物從舊事物那里脫胎而來,新事物是在批判地繼承舊事物中的一切積極的有生命力的因素的基礎(chǔ)上發(fā)展起來的。這樣,在新舊事物之間就存在著必然的聯(lián)系。
(2)歷史課本中歷朝歷代的文化發(fā)展。(3)政治生活中關(guān)于綜合國力競爭的相關(guān)知識。(4)了解文化產(chǎn)業(yè)的發(fā)展,深入體會知識經(jīng)濟、文化經(jīng)濟現(xiàn)象。五、【方法點津】:(1)堅持理論聯(lián)系實際的方法,感悟文化現(xiàn)象,理解文化內(nèi)涵,分析文化的作用,增強文化學習的自覺性。(2)自學探究。以課本的簡單提示為線索,深入探究文化與經(jīng)濟、政治的相互交融,探究文化在綜合國力競爭中的地位和作用。(3)集體討論。針對當前國際競爭的實質(zhì),探討我國應如何發(fā)展文化產(chǎn)業(yè)、發(fā)展文化生產(chǎn)力、增強文化競爭力;討淪為更好地應對文化競爭,作為中學生目前應做好哪些準備。六、【課文導語】:文化,一個我們十分熟悉的詞匯。然而“熟知并非真知”。有人說,文化是知識;有人說,文化是藝術(shù)。究竟什么是“文化”?只要在社會生活中細細體味,我們就能真切地感悟“文化”的內(nèi)涵與文化的力量。
在數(shù)學上,0這個數(shù)是解決記數(shù)和進位問題而引進的概念,由于它不能表示實在的東西,很長時間人們不把它看作是一個數(shù)。認為0是無,是對有的否定。從唯物辯證法的觀點看,這種否定不是形而上學的簡單否定,而是具有豐富內(nèi)容的辨證否定。辨證的否定是發(fā)展的環(huán)節(jié)。0是從無到有的必經(jīng)之路,是連接無和有的橋梁。0又是正數(shù)和負數(shù)之間的界限,它既否定了任何正數(shù),也否定了任何負數(shù),是唯一的中性數(shù)。但它又是聯(lián)結(jié)正數(shù)和負數(shù)的中間環(huán)節(jié)。沒有0,負數(shù)就過渡不到正數(shù)去,正數(shù)也休想發(fā)展到負數(shù)來。數(shù)學中的0是對任何定量的否定。如果沒有這一否定,任何量的發(fā)展都無從談起。這個否定不是一筆勾銷,而是揚棄。因為它克服了任何定量的有限性,成為其發(fā)展的環(huán)節(jié)。在現(xiàn)實生活中,0作為辨證的否定,也體現(xiàn)出聯(lián)系和發(fā)展的性質(zhì)。如0度不是沒有溫度,而是非常確定的溫度。
世界能源問題的解決途徑是什么?能源,是人類敕以生存和進行生產(chǎn)的不可缺少的資源.近年來,隨著生產(chǎn)力的發(fā)展和能源消費的增長.能源問題已被列為世界上研究的重大問題之一.解決世界能源問題的根本途徑,主要有兩個方面:其一是廣泛開源,其二是認真節(jié)流.所謂開源,就是積極開發(fā)和利用各種能源.在繼續(xù)加緊石油勘探和尋找新的石油產(chǎn)地的同時,積極開發(fā)豐富的煤炭資源,還要大力開發(fā)水能,生物能等常規(guī)能源,加強核能、太陽能,風能、沼氣,海洋能,地熱能以及其他各種新能源的研究和利用,從而不斷擴大人類的能源資源的種類和來源.所謂節(jié)流,就是要大力提倡節(jié)約能源.節(jié)能是世界上許多國家關(guān)心和研究的重要課題,甚至有人把節(jié)能稱為世界的“第五大能源”,與煤、石油和天然氣、水能、核能等并列.在節(jié)能方面,在有計劃地控制人口增長的同時,重點要發(fā)揮先進科學技術(shù)的優(yōu)勢,提高各國的能源利用效率.
