⑦在我看來, 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.

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.

人教版新課標高中物理必修1力學(xué)單位制教案2篇
一、教材分析在初中階段，物理量單位的學(xué)習(xí)是學(xué)生較為困惑的問題之一。前面關(guān)于1N的規(guī)定給學(xué)生的印象總好像是有些隨意。尤其是牛頓、帕斯卡、安培、伏特、焦耳、瓦特等單位的規(guī)定。使得學(xué)生感動物理太復(fù)雜。事實上，只有把單位制放在整個物理學(xué)框架中加以認識，并且知識有了一定的積累。經(jīng)歷了充分的學(xué)習(xí)過程后才能體會物理量單位的命名和使用規(guī)則。體會到其中對一些單位進行規(guī)定的合理性和方便特征。物理學(xué)單位中，有很少幾個基本物理量，它們的單位就是基本單位。在進行了這種選定之后，其它物理量的單位就是根據(jù)它的定義式，有所選擇的其他物理量的單位共同確定的。國際單位制的建立和使用，不僅方便了國際間的交流，也逐漸成為科學(xué)研究中計算和運用的一種規(guī)范約束。中學(xué)生應(yīng)該注意學(xué)習(xí)，逐步習(xí)慣，在記錄、表達和計算中規(guī)范使用。二、教學(xué)目標（一）知識與技能1．了解什么是單位制，知道力學(xué)中的三個基本單位；2．認識單位制在物理計算中的作用

人教版新課標高中物理必修1速度變化快慢的描述─加速度說課稿2篇
本來比較速度變化的快慢也有兩種方法：一種是比較相同時間內(nèi)速度變化量的大??；另一種是比較發(fā)生相同的速度變化所需要的時間長短。但教材是將比較質(zhì)點位置移動快慢的思想直接遷移過來，通過實例分析，使學(xué)生明白不同運動物體的速度變化快慢不同，表現(xiàn)在速度的變化與發(fā)生這個變化所用時間的比值不同，從而引入加速度的定義方法a=△v/△t。加速度表示速度的變化快慢，包括速度增加的快慢和減小的快慢，不能誤認為只要有加速度的運動速度就一定是增加的。廣義地講，加速度不僅可以描述速度大小的變化快慢，而且也可以描述速度方向變化的快慢，本節(jié)教材只限定在直線運動的情景中討論。加速度的矢量性是一個難點，教材是以與速度方向相同或是相反來表述加速度的矢量性的。如果以初速度方向為正方向，那么加速度就有正負之分，加速度的正負表示加速度的方向，不表示加速度的大小。

（三）合作交流能力提升教師：剛才我們通過實驗了解了小車的速度是怎樣隨時間變化的，但實驗中有一定的誤差，請同學(xué)們討論并說出可能存在哪些誤差，造成誤差的原因是什么？（每個實驗小組的同學(xué)之間進行熱烈的討論）學(xué)生：測量出現(xiàn)誤差。因為點間距離太小，測量長度時容易產(chǎn)生誤差。教師：如何減小這個誤差呢？學(xué)生：如果測量較長的距離，誤差應(yīng)該小一些。教師：應(yīng)該采取什么辦法？學(xué)生：應(yīng)該取幾個點之間的距離作為一個測量長度。教師：好，這就是常用的取“計數(shù)點”的方法。我們應(yīng)該在紙帶上每隔幾個計時點取作一個計數(shù)點，進行編號。分別標為：0、1、2、3……，測各計數(shù)點到“0”的距離。以減小測量誤差。教師：還有補充嗎？學(xué)生1：我在坐標系中描點畫的圖象只集中在坐標原定附近，兩條圖象沒有明顯的分開。學(xué)生2：描出的幾個點不嚴格的分布在一條直線上，還能畫直線嗎？

培養(yǎng)學(xué)生合作交流意識和探究問題的能力，這一部分知識層層遞進，符合學(xué)生由特殊到一般、由簡單到復(fù)雜的認知規(guī)律。4、互動探究(1)極限思想的滲透讓學(xué)生閱讀“思考與討論”小版塊.培養(yǎng)學(xué)生的自學(xué)和閱讀能力提出下列問題，進行分組討論：a、用課本上的方法估算位移，其結(jié)果比實際位移大還是小？為什么？b、為了提高估算的精確度，時間間隔小些好還是大些好？為什么？針對學(xué)生回答的多種可能性加以評價和進一步指導(dǎo)。讓學(xué)生從討論的結(jié)果中歸納得出：△t越小，對位移的估算就越精確。滲透極限的思想。通過小組內(nèi)分工合作，討論交流，培養(yǎng)學(xué)生交流合作的精神，以及搜集信息、處理信息的能力；通過小組間對比總結(jié)，使學(xué)生學(xué)會在對比中發(fā)現(xiàn)問題，在解決問題過程中提高個人能力；
