“做功的過程就是能量轉(zhuǎn)化過程”,這是本章教學(xué)中的一條主線。對于一種勢能,就一定對應(yīng)于相應(yīng)的力做功。類比研究重力勢能是從分析重力做功入手的,研究彈簧的彈性勢能則應(yīng)從彈簧的彈力做功入手。然而彈簧的彈力是一個變力,如何研究變力做功是本節(jié)的一個難點(diǎn),也是重點(diǎn)。首先,要引導(dǎo)學(xué)生通過類比重力做功和重力勢能的關(guān)系得出彈簧的彈力做功和彈簧的彈性勢能的關(guān)系。其次,通過合理的猜想與假設(shè)得出彈簧的彈力做功與哪些物理量有關(guān)。最后,類比勻變速直線運(yùn)動求位移的方法,進(jìn)行知識遷移,利用微元法的思想得到彈簧彈力做功的表達(dá)式,逐步把微分和積分的思想滲透到學(xué)生的思維中。本節(jié)課通過游戲引入課題,通過生活中拉弓射箭、撐桿跳高和彈跳蛙等玩具以及各種彈簧等實(shí)例來創(chuàng)設(shè)情景,提出問題。給學(xué)生感性認(rèn)識,引起學(xué)生的好奇心;讓學(xué)生對彈簧彈力做功的影響因素進(jìn)行猜想和假設(shè),提出合理的推測,激發(fā)學(xué)生的探索心理,構(gòu)思實(shí)驗(yàn),為定性探究打下基礎(chǔ)。然后,引導(dǎo)學(xué)生通過類比重力做功與重力勢能的關(guān)系得出彈簧彈性勢能與彈簧彈力做功的關(guān)系。

提問:阿根廷牧牛業(yè)以肉牛為主,那除肉牛以外還有哪種類型的牛呢?(奶牛)引入乳畜業(yè)。下面我們就來學(xué)習(xí)乳畜業(yè)。板書:二、乳畜業(yè)講述:乳畜業(yè)隨著城市發(fā)展而形成的面向城市市場的商品化、集約化畜牧業(yè)地域類型,其生產(chǎn)對像主要是奶牛。活動:請大家閱讀52-53面內(nèi)容,思考下列問題:提問:1、乳畜業(yè)產(chǎn)品有哪些?(牛奶及其制品)2、乳畜業(yè)主要分布在哪些地區(qū)呢?3、乳畜業(yè)是靠近消費(fèi)市場好還是遠(yuǎn)離市場好?為什么?板書:1、產(chǎn)品種類產(chǎn)品:牛奶及其制品,如奶粉、黃油和奶酪。2、分布:北美洲五大湖周圍地區(qū)、西歐、中歐,以及澳大利亞、新西蘭等地。3、多緊鄰消費(fèi)市場(由于牛奶及大部分乳制品不耐貯藏,且運(yùn)輸不便)目前,世界上許多大城市都有奶牛農(nóng)場分布于市郊。我國北京、上海等大城市周圍也發(fā)展了乳畜業(yè)。活動:第53面及第54面的活動題。
2、建立國際新秩序(1)建立國際新秩序是解決和平與發(fā)展問題的有效途徑為了和平與發(fā)展,必須改變舊的國際秩序,建立以和平共處五項原則為基礎(chǔ)的有利于世界和平與發(fā)展的國際新秩序。這是抑制霸權(quán)主義、強(qiáng)權(quán)政治,解決和平與發(fā)展問題的有效途徑,是每個國家生存和發(fā)展的最基本和最重要的外部條件。教師活動:引導(dǎo)學(xué)生閱讀教材103頁“相關(guān)鏈接”材料,并思考所反映的問題學(xué)生活動:積極思考并討論問題教師點(diǎn)評:世界發(fā)展的主體是世界各國人民。世界的管理必須由各國人民共同參與。這是各國人民的共同呼聲。(2)國際政治經(jīng)濟(jì)新秩序的主要內(nèi)容建立國際政治經(jīng)濟(jì)新秩序,就是要保障各國享有主權(quán)平等和內(nèi)政不受干涉的權(quán)利,保障各國享有平等參與國際事務(wù)的權(quán)利,保障各國特別是廣大發(fā)展中國家享有平等的發(fā)展權(quán)利,保障各個民族和各種文明共同發(fā)展的權(quán)利。

總之,依法維護(hù)勞動者合法權(quán)益,是保障勞動者主人翁地位的前提,是充分調(diào)動勞動者積極性、創(chuàng)造性,使之成為改革開放和社會主義建設(shè)主力軍的保證。也是促進(jìn)勞動力資源合理配置,促進(jìn)經(jīng)濟(jì)持續(xù)、快速、健康發(fā)展的需要。(三)課堂總結(jié)、點(diǎn)評★課余作業(yè)某企業(yè)由于生產(chǎn)任務(wù)較大,在未經(jīng)勞動行政部門批準(zhǔn)的情況下,廠長強(qiáng)行讓部分職工延長勞動時間,每天加時工作,星期天也照常上班,不讓休息。到月底,部分職工全月累計加班加點(diǎn)高達(dá)120小時,也不發(fā)加班工資。根據(jù)上述材料回答:你認(rèn)為該廠的做法是否合法?為什么?勞動者依法享有哪些權(quán)利?該廠的做法侵害了勞動者的哪些權(quán)利?這些工人應(yīng)當(dāng)怎么辦?★教學(xué)體會本節(jié)學(xué)習(xí)勞動者的權(quán)利和樹立什么樣的就業(yè)觀等問題,與大家的生活聯(lián)系比較密切。因此,在講解過程中要通過大量的實(shí)例和對比,引導(dǎo)學(xué)生思考和討論,將市場經(jīng)濟(jì)中的一些理論知識潛移默化的給學(xué)生。
問題:1、對田納西河流域進(jìn)行開發(fā)能產(chǎn)生哪些方面的效益?2、如果只 提高土地利用程度,是否能保證其他方面的效益不受影響?如果受影響分別說明產(chǎn)生了什么后果?應(yīng)如何治理?這體現(xiàn)了地理環(huán)境的什么特性。(學(xué)生讀課文歸納總結(jié))讀問題研究內(nèi)容,思 考下列問題1、 阿斯旺大壩位于哪個國家?它的建立為該國農(nóng) 業(yè)生產(chǎn)提供了哪些有利條件?2、 阿斯旺大壩的建立帶來了哪些經(jīng)濟(jì)效益?又產(chǎn)生了哪些不利影響?3、 我們應(yīng)如何評價這一工程利與弊?它對我國三峽大壩的建設(shè)有什么借鑒意義。同學(xué)們,通過本課的學(xué)習(xí)我們已深切地感受到河流流域的綜合開發(fā)給我們的生活帶來了巨大的改變,但我們更應(yīng)看到人類的 經(jīng)濟(jì)活動對生態(tài)環(huán)境產(chǎn)生的不利影響,怎樣才能趨利避害,造福人類,這是我們每個人都應(yīng)思考的問題。

Listening and Speaking introduces the topic of “how to save endangered wildlife and help wildlife in their neighborhood.” Due to the continuous deterioration of the living environment, a large number of wild animals are always facing the threat of endangered or extinction. Listening and speaking period enables students to understand the fact and reason why wild species are disappearing from the earth at an amazing speed, and realize that human beings ought to enhance the awareness of protecting wild species as soon as possible.Listening and Talking introduces the theme of " how to help wildlife in Ss’ neighborhood.". Now there are many volunteers who spontaneously protect wild animals, carry out various activities according to local conditions, and contribute their own strength to local animal protection with practical actions. Middle school students are also enthusiastic participants. They organize activities in their spare time, and take this opportunity to make friends, broaden their horizons, cultivate team spirit and communication skills. This section describes a bird watching activity organized by several middle school students of Bird watching Club. It aims to stimulate students' interest, improve their understanding of bird watching activities, and use the language structure of “being used for; in order to, so as to, to, so that, in order that ” to express the purpose for communication and discussion.1. Guide students to understand the content of listening texts in terms of using visuals to predict content.2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to save endangered wildlife and help wildlife in their neighborhood.3. Instruct students to use functional sentences of the dialogue such as “I am concerned about…” “what do you know about the endangered animals in…" and so on to talk about one of the endangered animals.

The activity topic of this section is "report an ongoing event", and the structure is the passive voice of present continuous tense. Rare wild animals are suffering from large-scale poaching, and species are on the brink of danger. Rescue operations are underway. "Being" and "suffering" are the meanings of the present progressive passive voice.The usage of present progressive passive voice is of great importance in writing a good discourse and appreciating some difficult language items, so it is vital to master it and use it flexibly in a context.1. Motivate Ss to deepen the understanding of the usage of present progressive passive voice in a fixed context.2. Enable Ss to master the usage of present progressive passive voice and use it flexibly in a context.3. Lead Ss to construct sentences or appreciate sentences used master it and use it flexibly in a context.1. Help students to appreciate the function of the usage of present progressive passive voice in a sentence2. Instruct students to write essays using the proper usage of present progressive passive voice.Look at the picture and tell me what are workers doing? What is the house being done?

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.
