    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(fù)合句中的作用是什么? 關(guān)系詞有哪些?定語從句在復(fù)合句中的作用相當(dāng)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(dān)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。

    人教版新課標(biāo)高中物理必修1摩擦力教案2篇

    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(xué)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(xué)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(xué)生有初中的知識,往往誤認(rèn)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(dāng)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。

    國旗下的講話:做一個有道德的人

    國旗下的講話:做一個有道德的人老師們、同學(xué)們:大家上午好!今天我講的題目是《做一個有道德的人》。意大利詩人但丁曾說過:“一個知識不健全的人,可以用道德來彌補,而一個道德不健全的人,卻難以用知識來彌補。”上下五千年以來,道德一直是我們?nèi)A夏兒女的寶藏。道德,是一種美德,是一種財富,更是一種智慧。道德源自于我們的內(nèi)心,有了道德感,自己做出的事情自然就不會錯。做好事,不是為了得到誰的表揚,得到怎樣的榮譽。真正的道德,發(fā)自內(nèi)心,你對社會,對每個人的愛,就是一份珍貴的道德。文明很小很小,但是只要每一個人都做文明的好事,就能使社會文明邁出一大步。一件小事很小很小,但是用處卻很大很大。每一份文明就是一份力量,無數(shù)文明在一起就會產(chǎn)生一種無與倫比的力量,這種力量如破土的小苗,在每一個人的心里萌發(fā)。
