Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

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.

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.

(一)地位《生活中的圓周運(yùn)動(dòng)》這節(jié)課是新課標(biāo)人教版《物理》必修第二冊(cè)第5章《曲線(xiàn)運(yùn)動(dòng)》一章中的第7節(jié),也是該章最后一節(jié)。本節(jié)課是在學(xué)生學(xué)習(xí)了圓周運(yùn)動(dòng)、向心加速度、向心力以后的一節(jié)應(yīng)用課,通過(guò)研究圓周運(yùn)動(dòng)規(guī)律在生活中的具體應(yīng)用,使學(xué)生深入理解圓周運(yùn)動(dòng)規(guī)律,并且結(jié)合日常生活中的某些生活體驗(yàn),加深物理知識(shí)在頭腦中的印象。(二)教材處理教材中的“火車(chē)轉(zhuǎn)彎”與“汽車(chē)過(guò)拱橋”根據(jù)學(xué)生接受的難易程度,順序作了對(duì)調(diào),并把最后一部分“離心運(yùn)動(dòng)”放到下一節(jié)課處理。(三)教學(xué)目標(biāo)1.知識(shí)與技能目標(biāo)(1)進(jìn)一步加深對(duì)向心力的認(rèn)識(shí),會(huì)在實(shí)際問(wèn)題中分析向心力的來(lái)源。(2)培養(yǎng)學(xué)生獨(dú)立觀察、分析問(wèn)題、解決問(wèn)題的能力,提高學(xué)生概括總結(jié)知識(shí)的能力。(3)了解航天器中的失重現(xiàn)象。2.過(guò)程與方法目標(biāo)(1)學(xué)會(huì)分析圓周運(yùn)動(dòng)方法,會(huì)分析拱形橋、彎道等實(shí)際的例子,培養(yǎng)理論聯(lián)系實(shí)際的能力。
一、教材分析下面我來(lái)談一談對(duì)教材的認(rèn)識(shí):主要從教材的地位和作用、以及在此基礎(chǔ)上確立的教學(xué)目標(biāo)、教學(xué)重難點(diǎn)這三個(gè)方面來(lái)談。首先,來(lái)談教材的地位和作用:本課教材內(nèi)容主要從三個(gè)方面向?qū)W生介紹了現(xiàn)代中國(guó)教育的發(fā)展?fàn)顩r和趨勢(shì):人民教育的奠基、動(dòng)亂中的教育和教育的復(fù)興,全面講述了新中國(guó)教育的三個(gè)階段。本課是文化史中中國(guó)史部分的最后一課, 也是必修三冊(cè)書(shū)中唯一涉及教育的一課。而教育是思想文化史中的重要組成部分,江澤民同志在談到教育的時(shí)候曾經(jīng)說(shuō)過(guò),“百年大計(jì),教育為本。教育為本,在于育人”。教育是關(guān)系國(guó)計(jì)民生的大事。學(xué)生通過(guò)學(xué)習(xí)新中國(guó)教育發(fā)展的史實(shí),理解“科教興國(guó)”、“國(guó)運(yùn)興衰,系于教育”的深刻含義。最終由此激發(fā)學(xué)生樹(shù)立“知識(shí)改變命運(yùn)、讀書(shū)成就人生”的信念,樹(shù)立勤奮學(xué)習(xí)、成人成才、報(bào)效祖國(guó)、服務(wù)社會(huì)的崇高理想。故本課的教學(xué)有極大的現(xiàn)實(shí)意義。談完了教材的地位和作用,我再分析一下教學(xué)目標(biāo):
蘇格拉底把裝有毒酒的杯子舉到胸口,平靜地說(shuō):“分手的時(shí)候到了,我將死,你們活下來(lái),是誰(shuí)的選擇好,只有天知道?!闭f(shuō)畢,一口喝干了毒酒。(2) 蘇格拉底臨死前對(duì)一個(gè)叫克力同的人說(shuō)了這樣一番話(huà)??肆ν?,我告訴你,這幾天一直有一個(gè)神的聲音在我心中曉喻我,他說(shuō):“蘇格拉底,還是聽(tīng)我們的建議吧,我們是你的衛(wèi)士。不要考慮你的子女、生命或其他東西勝過(guò)考慮什么是公正?!聦?shí)上你就要離開(kāi)這里了。當(dāng)你去死的時(shí)候,你是個(gè)犧牲品,但不是我們所犯錯(cuò)誤的犧牲品,而是你同胞所犯錯(cuò)誤的犧牲品。但你若用這種可恥的方法逃避,以錯(cuò)還錯(cuò),以惡報(bào)惡,踐踏你自己和我們訂立的協(xié)議合約,那么你傷害了你最不應(yīng)該傷害的,包括你自己、你的朋友、你的國(guó)家,還有我們。到那時(shí),你活著面對(duì)我們的憤怒,你死后我們的兄弟、冥府里的法律也不會(huì)熱情歡迎你;因?yàn)樗鼈冎滥阍噲D盡力摧毀我們。別接受克力同的建議,聽(tīng)我們的勸告吧?!?/p>
