The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

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.

The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.

虛構(gòu)不等于說假話。它是一種源于生活，但高于生活的藝術(shù)真實(shí)。我們可以舉個例子：我國公認(rèn)的最權(quán)威最真實(shí)的史書是——《史記》，那么，大家認(rèn)為《史記》里有沒有虛構(gòu)呢？有。必修一的《鴻門宴》里就有虛構(gòu)。大家想：司馬遷是哪個朝代的人？西漢漢武帝時。劉邦項(xiàng)羽是哪個朝代的？秦末時期。那司馬遷不可能坐時光穿梭機(jī)到秦末去參加鴻門宴吧？既然他沒不在場，那課文《鴻門宴》里人物的語言、動作、甚至是表情從何而來呢？對，是司馬遷根據(jù)有限的史料加以補(bǔ)充，想象、虛構(gòu)出來的。那么，同學(xué)們在寫作文時，也可以不必拘泥于親身經(jīng)歷的事情，畢竟生活是平淡的，畢竟大家的生活閱歷也有限，有時候，我們發(fā)揮想象、虛構(gòu)一個故事來反映生活的真實(shí)，也許更生動、也更典型。所以，近年來高考試卷中都提示考生：作文可以大膽想象，編寫故事。按照編故事的方式不同，我們的虛構(gòu)性作文又可以寫哪些類型呢：小說，散文，童話，寓言，科幻，故事新編……

論證方法之引證法如何用好引證法：1.所引用的名言警句等針對性要強(qiáng)。每句名言都產(chǎn)生于特定的背景，都應(yīng)用于特定的交際目的，即使談同一個問題，也有不少名言可供選取。2.要簡潔，不宜過多。議論是在發(fā)表自己的見解而不是在介紹他人的見解。引用他人的話，目的是為了讓讀者更加信服自己的話。3.要注意直接引用和間接引用的區(qū)別。直接引用務(wù)求文字、甚至標(biāo)點(diǎn)均準(zhǔn)確無誤；間接引用只須述其大意，但要注意人稱的轉(zhuǎn)換。論證方法之喻證法喻證法是用設(shè)喻來論證論點(diǎn)的方法。在議論文中，設(shè)喻可以使論點(diǎn)更易懂、更風(fēng)趣、更容易獲得讀者的認(rèn)同。喻證法能化抽象為具體、化艱深為淺顯、化枯燥為生動。論證方法之喻證法如何用好喻證法：1.以小見大，就近取譬。要精選生活中細(xì)小的、人們熟悉的事物做為設(shè)喻的喻體。2.喻體不求形似，只求神似。做為喻證的喻體與做為比喻的喻體不同。比喻的喻體是為了強(qiáng)調(diào)特征，描繪事物，側(cè)重形似，以形比形；而喻證的喻體是為了闡發(fā)觀點(diǎn)，以正視聽，力求神似，以義取形。
人教版新課標(biāo)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(shí)上，只有把單位制放在整個物理學(xué)框架中加以認(rèn)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(jìn)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(jìn)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(jì)算和運(yùn)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(dá)和計(jì)算中規(guī)范使用。二、教學(xué)目標(biāo)（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(rèn)識單位制在物理計(jì)算中的作用
