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 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

本節(jié)課選自《普通高中課程標(biāo)準(zhǔn)數(shù)學(xué)教科書-必修一》（人 教A版）第五章《三角函數(shù)》，本節(jié)課是第1課時，本節(jié)主要介紹推廣角的概念,引入正角、負(fù)角、零角的定義，象限角的概念以及終邊相同的角的表示法。樹立運(yùn)動變化的觀點(diǎn),并由此進(jìn)一步理解推廣后的角的概念。教學(xué)方法可以選用討論法,通過實(shí)際問題，如時針與分針、體操等等都能形成角的流念,給學(xué)生以直觀的印象,形成正角、負(fù)角、零角的概念,明確規(guī)定角的概念，通過具體問題讓學(xué)生從不同角度理解終邊相同的角,從特殊到一般歸納出終邊相同的角的表示方法。A.了解任意角的概念；B.掌握正角、負(fù)角、零角及象限角的定義，理解任意角的概念；C.掌握終邊相同的角的表示方法；D.會判斷角所在的象限。 1.數(shù)學(xué)抽象：角的概念；2.邏輯推理：象限角的表示；3.數(shù)學(xué)運(yùn)算：判斷角所在象限；4.直觀想象：從特殊到一般的數(shù)學(xué)思想方法；
高中語文人教版必修二《歸園田居》說課稿
一、說教材本節(jié)課選自于人教版語文必修二第二單元詩三首中的一首詩歌，它是陶淵明歸隱后的作品。寫的是田園之樂，實(shí)際表明的是作者不愿與世俗同流合污的心聲，甘愿守著自己的拙志回歸田園。學(xué)習(xí)該詩，有助于學(xué)生了解山水田園詩的特點(diǎn)，感受者作者不同流俗的高尚情操，同時可以培養(yǎng)學(xué)生初步的鑒賞古典詩歌的能力。
