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。

劉邦:先看劉邦對項伯的表白(此話也是有意讓項伯轉(zhuǎn)述給項羽聽的):“秋毫不敢有所近”——說“不敢”而不說“不曾”,多么恭順!“籍吏民,封府庫,而待將軍”——“待”,多么虔誠!“日夜望將軍至”——說“望”而不說“等”,多么迫切!再看劉邦的卑詞“謝罪”:他言必稱“將軍”,說自己與項羽“戮力而攻秦”,是戰(zhàn)友而非敵人;將“先入關破秦”說成是不自意,以表自己的力量不如項羽;把“得復見將軍于此”當作是自己莫大的榮幸以滿足項羽的虛榮心;最后,他還把項羽的憤怒歸咎于“小人”的挑撥,為項羽推卸責任,及時給項羽一個臺階下。小結(jié):項羽:沽名釣譽、輕敵自大、寡謀輕信、不善用人、剛愎自用、優(yōu)柔寡斷的一介武夫。劉邦:狡詐多謀、遇事果斷、臨危不懼、能屈能伸、善于用人。
教學過程:一、交流誦讀課文技巧?!?jié)奏、韻腳、感情……(5分鐘)二、再讀確定自己的學習主題(15分)1、主題提示:音樂美、繪畫美、建筑美簡介詩歌“三美”追求聞一多先生是我國現(xiàn)代文學史上集詩人、學者和斗士于一身的重要詩人。他不但致力于新詩藝術美的探索,提出了音樂美、繪畫美、建筑美的詩歌\"三美\"的新格律詩理論主張,還努力進行創(chuàng)作實踐,寫出了許多精美詩篇。他的新格律詩理論被后人稱為現(xiàn)代詩學的奠基石,影響深遠?!对姷母衤伞肥锹勔欢嘞壬盗性娬撝凶钪匾囊黄T谶@篇論文中,他系統(tǒng)的提出\"詩的實力不獨包括音樂的美(音節(jié))、繪畫的美(詞藻),并且還有建筑的美(節(jié)的勻稱和句的均齊)。\"這一關于新詩\"三美\"主張遂成為新格律詩派的理論綱領。
3、介紹對聯(lián)的歷史引出本課的重點。人類歷史上的第一副對聯(lián)是“新年納余慶,嘉節(jié)號長春”。出現(xiàn)在五代十國時期(公元964年),距離現(xiàn)在已經(jīng)有1044年了。有著一千多年歷史的對聯(lián)有什么基本的特點呢?這是我們這節(jié)課學習的重點。請在座的各位當回醫(yī)生,給下面這幅對聯(lián)號號脈,看它對仗是否工整?上聯(lián):冬去春來千條楊柳迎風綠下聯(lián):冰消雪化梅花萬朵撲鼻有什么問題,怎么改?剛才這幾位同學指出了這幅對聯(lián)的兩個問題,也提出了兩條修改意見。第一是下聯(lián)少了一個字,最好是添加一個“香”字;第二是下聯(lián)的“梅花萬朵”與上聯(lián)的“千條楊柳”是數(shù)量詞對名詞,名詞對數(shù)量詞,對仗不工整,要調(diào)整為“萬朵梅花”。這樣,數(shù)量詞“萬朵”對“千條”,名詞“梅花”對“楊柳”。大家還有沒有不同的看法。這樣我們就可以得出對聯(lián)的兩個特點特點:第一個特點是上下聯(lián)字數(shù)要相等(板書)。就是上聯(lián)有幾個字,下聯(lián)也要有幾個字。大家記下來,對聯(lián)基本要求一,“上下聯(lián)字數(shù)相等”。這個要求是很嚴格的,一般來說,違反這個規(guī)則就不成對聯(lián)了。

【教材分析】高考聽力材料的選用非常重視語言真實性和交際性的原則,語言材料一般來源于實際生活,對話的內(nèi)容大都取材于日常生活,即衣、食、住、行、工作、學習、天氣、生活環(huán)境等話題,可分為校園、公共場所、家庭等方面,如: shopping, finding the way, doing one’s homework, seeing a doctor, making a phone call, weather report, asking for different kinds of information等。新教材的特點就是利用生活中真實文本,只是降低難度,讓學生注重語言的應用,將是我們高考把握方向的重要因素?!窘虒W目標與核心素養(yǎng)】學習能力目標:在聽力當中,學生應該有效規(guī)劃學習方法,選擇恰當?shù)牟呗耘c方法。這節(jié)課的訓練目標是讓學生有正確的預測和抓住問題的關鍵信息,從而用心去聽來找尋關鍵信息。根據(jù)生活中實際情況和高考常見語境,我們不難發(fā)現(xiàn)提前預測和抓住題干中的w很重要,即what, where, when, why等等。
常跟雙賓語的動詞有:(需借助to的)bring, ask, hand, offer, give, lend, send, show, teach, tell, write, pass, pay, promise, return等;基本句型 五S +V + O + OC(主+謂+賓+賓補)特點:動詞雖然是及物動詞,但是只跟一個賓語還不能表達完整的意思,必須加上一個補充成分來補足賓語,才能使意思完整。 判斷原則:能表達成—賓語 是…/做…注:此結(jié)構(gòu)由“主語+及物的謂語動詞+賓語+賓語補足語”構(gòu)成。賓語與賓語補足語之間有邏輯上的主謂關系或主表關系,若無賓語補足語,則句意不夠完整。可以用做賓補的有:名詞,形容詞,副詞,介詞短語,動詞不定式,分詞等。如:He considers himself an expert on the subject.他認為自己是這門學科的專家。We must keep our classroom clean.我們必須保持教室清潔。I had my bike stolen.我的自行車被偷了。We invited him to come to our school.我們邀請他來我們學校。I beg you to keep secret what we talked here.我求你對這里所談的話保密。用it做形式賓語,而將真正的賓語放到賓語補足語的后面,以使句子結(jié)構(gòu)平衡,是英語常用的句型結(jié)構(gòu)方式。即:主語+謂語+it+賓補+真正賓語。如:We think it a good idea to go climb the mountain this Sunday.

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. Temples and other cultural sites were taken down piece by piece, and then moved and put back together again in a place where they were safe from the water.Step 2 PracticePlease complete these sentences with relative pronouns and relative adverbs and answer the following questions.Questions: 1.

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.
