Listening and Speaking introduces the topic of “Take part in a youth project”. The listening text is an interview about "sharing views on historical sites". Through listening to a dialogue between Chinese and foreign students on the way to the Confucius Temple, students can understand their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts, so as to realize and think about the profound influence of Confucius and his thoughts on Chinese historical tradition. At the same time, the dialogue naturally integrates English idioms and mentions Shakespeare, the British playwright, so as to provide language materials and context for students to understand English idioms and related cultural allusions, as well as to compare Chinese and foreign cultures, which is helpful for students to understand and express the language such as history, tradition, culture and custom significant impact.Text analysis: listening text is a dialogue between a British student and a Chinese student when he goes to the Confucius Temple. When William, a British student, visited the Confucius Temple, he asked Xiao Kong, a Chinese student, for directions. Xiao Kong was just going to the Confucius Temple to meet with the members of the research group, so they went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts. From the perspective of foreign tourists, this paper describes their thoughts on Confucius, the great son of Confucius, who had a profound impact on Chinese history and cultural tradition, and his education.Listening and Talking introduces a visit to a historic tourist destination. Tourism is a common way to understand a country's history, culture, and customs and so on. Students listen to the dialogue between Xiao Yan, a youth hostel Usher, and Paul, a backpacker, to learn about Pingyao's famous historical and cultural attractions and Paul's travel experience and experience as a foreign tourist.
The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life. Thank you for your listening !5.Revise your writing each other.Does he/she explain how music has changed his/her/someone else’s life?Are some of the rhetorical devices included and used properly ?Does he/she talk about how music makes him/her/someone feel?Is the first word in each sentences capitalised?Does he/she use correct punctuation ?

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.

③于是,大自然出現(xiàn)了驚人的奇跡,不毛的石縫間叢生出倔強的生命。④或者就只是一簇一簇無名的野草,春綠秋黃。歲歲枯榮。它們只有三兩片長長的細瘦的薄葉,那細微的葉脈,告知你生存該是多么艱難;更有的。它們就在一簇一簇瘦葉下自己生長出根須,只為了少向母體吮吸一點乳汁,便自去尋找那不易被覺察到的石縫。這就是生命,如果這是一種本能,那么它正說明生命的本能是多么尊貴,生命有權(quán)自認為輝煌壯麗,生機竟是這樣地不可扼制。⑤或者就是一團一團小小的山花,大多又都是那苦苦的蒲公英。它們不似田野上的同宗長得那樣茁壯,它們的莖顯得堅韌而蒼老。它們的葉因枯萎而失卻光澤。它們已經(jīng)不能再去為人們作佐餐的鮮嫩的野菜,卻默默地為攀登山路的人準備了一個可靠的抓手。生命就這樣地被環(huán)境規(guī)定著,又被環(huán)境改變著,適者生存的規(guī)律盡管無情。但一切適者就是戰(zhàn)勝環(huán)境的強者。生命現(xiàn)象告訴你,生命就是拼搏。
一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復(fù)原狀,對桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導學生分析靜止時,懸繩對重物的拉力及方向。引導得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產(chǎn)生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產(chǎn)生豎直向上的彈力f2,這就是繩對物體的拉力。
l.知識與技能:(1)知道摩擦力產(chǎn)生的條件。(2)能在簡單問題中,根據(jù)物體的運動狀態(tài),判斷靜摩擦力的有無、大小和方向;知道存在著最大靜摩擦力。(3)掌握動磨擦因數(shù),會在具體問題中計算滑動磨擦力,掌握判定摩擦力方向的方法。(4)知道影響到摩擦因數(shù)的因素。2.過程與方法:通過觀察演示實驗,概括出摩擦力產(chǎn)生的條件及摩擦力的特點,培養(yǎng)學生的觀察、概括能力。通過靜摩擦力與滑動摩擦力的區(qū)別對比,培養(yǎng)學生分析綜合能力。3.情感態(tài)度價值觀:在分析物體所受摩擦力時,突出主要矛盾,忽略次要因素及無關(guān)因素,總結(jié)出摩擦力產(chǎn)生的條件和規(guī)律。二、重點、難點分析1.本節(jié)課的內(nèi)容分滑動摩擦力和靜摩擦力兩部分。重點是摩擦力產(chǎn)生的條件、特性和規(guī)律,通過演示實驗得出關(guān)系f=μN。2.難點是學生有初中的知識,往往誤認為壓力N的大小總是跟滑動物體所受的重力相等,因此必須指出只有當兩物體的接觸面垂直,物體在水平拉力作用下,沿水平面滑動時,壓力N的大小才跟物體所受的重力相等。
(五)平拋運動規(guī)律的應(yīng)用例1:一架老式飛機在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機上投下的炸彈落在停在海面上的敵船,應(yīng)該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。分析:對于這道題我們可以從以下幾個方面來考慮:(1)從水平飛行的飛機上投下的炸彈,做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標處,你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標的水平距離之間有什么關(guān)系?拓展:1、式飛機在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機上投下的炸彈正好擊中敵船,應(yīng)該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點,不計空氣阻力。(1)判斷摩托車能否跨越壕溝?請計算說明(2)若能跨過,求落地速度?
3.進一步體會力是產(chǎn)生加速度的原因,并通過牛頓第二定律來理解勻速圓周運動、變速圓周運動及一般曲線運動的各自特點。(三)、情感、態(tài)度與價值觀1.在實驗中,培養(yǎng)學生動手、探究的習慣。2.體會實驗的意義,感受成功的快樂,激發(fā)學生探究問題的熱情、樂于學習的品質(zhì)。教學重點1.體會牛頓第二定律在向心力上的應(yīng)用。2.明確向心力的意義、作用、公式及其變形,并經(jīng)行計算。教學難點1.對向心力的理解及來源的尋找。2.運用向心力、向心加速度的知識解決圓周運動問題。教學過程(一)、 引入新課:復(fù)習提問:勻速圓周運動的物體的加速度——向心加速度,它的方向和大小有何特點呢?學生回答后進一步引導:那做勻速圓周運動物體的受力有什么特點呢?是什么力使物體做圓周運動而不沿直線飛出?請同學們先閱讀教材
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(yīng)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)。
(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(yīng)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(yīng)對文化競爭,作為中學生目前應(yīng)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。
1.加強社會主義文化建設(shè)的必要性在人類歷史的長河中,各種思想文化總是相互沖擊、交匯、融合.奔騰向前,永不停息。今天,我們面對的文化有傳統(tǒng)的和現(xiàn)代的、外來的和本土的、進步的和落后的、先進的和腐朽的、積極的和頹廢的,等等。各種各樣的文化有吸納又有排斥,有融合又有斗爭,有滲透又有抵御,呈現(xiàn)出前所未有的相互交織、相互激蕩之勢。在這種文化發(fā)展的大背景下,在我國現(xiàn)代化建設(shè)過程中,有必要弘揚我國社會主義的主流文化,這樣有利于保證我國社會主義文化發(fā)展的方向。2.大力加強社會主義文化建設(shè)(1)中國特色社會主義文化在我國文化生活中處于主導地位。中國特色社會主義文化,始終堅持以科學的理論武裝人,以正確的輿論引導人,以高尚的精神塑造人,以優(yōu)秀的作品鼓舞人,無論是思想內(nèi)容還是表現(xiàn)形式,都發(fā)揮著強有力的導向和示范作用。社會主義文化以其自身的科學性和先進性,并依靠社會主義政治和經(jīng)濟力量,在人民大眾的文化生活中始終占據(jù)著主導地位。

一、教材分析第四單元“發(fā)展社會主義市場經(jīng)濟”旨在培養(yǎng)社會主義的建設(shè)者,高中生是未來社會主義現(xiàn)代化建設(shè)的主力軍,是將來參與市場經(jīng)濟活動的主要角色,承擔著全面建設(shè)小康社會的重任,本課的邏輯分為兩目:第一目,從“總體小康到全面小康”。這一部分的邏輯結(jié)構(gòu)如下:首先謳歌我國人民的生活水平達到總體小康這一偉大成就,然后從微觀和宏觀兩個方面介紹總體小康的成就。同時指出,我國現(xiàn)在達到的小康是低水平、不全面、發(fā)展不平衡的小康。第二目“經(jīng)濟建設(shè)的新要求”。這一目專門介紹全面建設(shè)小康社會的經(jīng)濟目標,也是學生要重點把握的內(nèi)容。二、教學目標(一)知識目標(1)識記總體小康的建設(shè)成就在宏觀和微觀上的表現(xiàn),全面建設(shè)小康社會的經(jīng)濟建設(shè)目標。(2)理解低水平、不全面、發(fā)展很不平衡的小康,以及小康社會建設(shè)進程是不平衡的發(fā)展過程。(3)運用所學知識,初步分析全面建設(shè)小康社會的意義。
