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.

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(yǔ)法思考：定語(yǔ)從句在復(fù)合句中的作用是什么？ 關(guān)系詞有哪些？定語(yǔ)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(yǔ)修飾名詞或代詞。他們?cè)谙刃性~和定語(yǔ)從句之間起到聯(lián)系作用，同時(shí)在意義上代表先行詞并在定語(yǔ)從句中擔(dān)任一個(gè)成分。被定語(yǔ)從句所修飾的詞稱(chēng)先行詞，定語(yǔ)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彈力教案2篇
一般情況下，凡是支持物對(duì)物體的支持力，都是支持物因發(fā)生形變而對(duì)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(shū)書(shū)由于重力的作用而壓迫桌面，使書(shū)和桌面同時(shí)發(fā)生微小形變，要恢復(fù)原狀，對(duì)桌面產(chǎn)生垂直于桌面向下的彈力f1，這就是書(shū)對(duì)桌面的壓力；桌面由于發(fā)生微小的形變，對(duì)書(shū)產(chǎn)生垂直于書(shū)面向上的彈力f2，這就是桌面對(duì)書(shū)的支持力。學(xué)生分析：靜止地放在傾斜木板上的書(shū)，書(shū)對(duì)木板的壓力和木板對(duì)書(shū)的支持力。并畫(huà)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(dǎo)學(xué)生分析靜止時(shí)，懸繩對(duì)重物的拉力及方向。引導(dǎo)得出：懸掛物由于重力的作用而拉緊懸繩，使重物、懸繩同時(shí)發(fā)生微小的形變。重物由于發(fā)生微小的形變，對(duì)懸繩產(chǎn)生豎直向下的彈力f1，這是物對(duì)繩的拉力；懸繩由于發(fā)生微小形變，對(duì)物產(chǎn)生豎直向上的彈力f2，這就是繩對(duì)物體的拉力。
