人教版新课标高中物理必修2重力势能说课稿2篇
（四）、弹性势能（据课时情况，可以让学生自学）生活中还有一些物体既没有运动也没有很大的高度却同样“储存”着能量，哪怕它只是孩童手里的玩具（图片：弹弓）。张紧的弓一撒手就会对箭支做功改变它的动能，松弛的弓有这样的本领吗？同样是弓前者具有能量而后者没有，那么什么情况下物体才具有这种能量呢？张紧的弓在恢复原状的过程会对外做功，但是拉断的弓还能有做功的本领吗？1．定义：物体由于发生弹性形变而具有的能量叫做弹性势能。2．弹性势能的大小与哪些因素有关呢？3、势能由相互作用的物体的相对位置决定的能量。重力势能：由地球和物体间相对位置决定。弹性势能：由发生形变的各部分的相对位置决定。(五).反馈练习1. 物体在运动过程中，克服重力做功50J， 则( )A．重力做功为50JB．物体的重力势能一定增加50JC．物体的重力势能一定减少50JD．重力做功为-50J
人教版高中历史必修2古代商业的发展说课稿2篇
【课标要求】： 概述古代中国商业发展的概貌，了解古代中国商业发展的特点。 【教材地位】： 本课第一目“重农抑商下的古代商业”概述了各个时期商业发展的主要表现及其艰难处境；第二目“市的变迁和城市的发展”介绍了城市作为古代商业发展的中心在格局和职能等方面的变化；第三目“官府控制下的对外贸易”概述了古代中国对外贸易的概貌。 “无农不稳，无工不富，无商不活”。 古代中国商业发展的特点，决定了本课与本单元其他各部分之间具有不可分割的联系。因此，本课虽然不直接叙述农业、手工业的内容，但一定要以此前已经讲述过的农业发展及其特点、手工业发展及其特点为基础。 商业文明脱胎于农耕文明，同时又有着不一样的特质。在农耕文明的大背景下，商业在重农抑商的环境中仍顽强发展，不断突破，明清时达到鼎盛，呈现出中国商业文明特有的魅力。遗憾的是，没能像西方一样打开工业文明的大门。引导学生思考的同时，为下一节古代的经济政策做好铺垫。

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
