    第十周國旗下講話稿:愛國

    老師們、同學們:早上好,我今天講話的主題就是愛國。天下興亡匹夫有責,位卑未敢忘國。我們每個人都與國家休戚與共。每周一當我們站在這里,唱著雄壯激昂的國歌,目睹著五星紅旗冉冉升起,高呼國家的利益高于一切時,在這種莊嚴肅穆的氛圍中,我們的國家意識越來越強。這是愛國主義教育的一部分。其實古今中外無論哪一個國家都以愛國主義為凝結的風氣,動員和激勵人們團結起來。我們來看看一些發(fā)達國家是怎樣做的。美國孩子從幼兒園開始就要學習畫國旗、唱國歌。一上小學,每天早晨,都要參加唱國歌、升國旗儀式,把右手放在左胸前,宣誓效忠國家。美國籃球、橄欖球或棒球等重大體育賽事,都有一個保留節(jié)目,就是在開場前全場起立,由著名歌手領唱美國國歌。還有我們熟悉的美國電影也帶有很濃厚的愛國色彩,好萊塢的許多大片都在向世界宣揚“美國精神”,夸張得渲染美國有多厲害。再看看日本,日本目前有許多學校正積極推行二戰(zhàn)前的愛國思想教育,老師們還在成績單上分A、B、c給學生們打“愛國分”。日本的新歷史教科書在涉及鄰國及侵華戰(zhàn)爭的重大歷史問題,總是上極盡歪曲、篡改。

    大家好:大家都知道,由于人類向自然界過度的索取,已經導致了大自然無情的報復:颶風、暴雨、暴風雪、洪澇、干旱、蟲害、酷暑、森林大火、地震、海嘯等災情不期而至,全世界因干旱等原因而造成的遷移性難民預計到2025年達到1億人。所有這一切都在向人類發(fā)出警示:人類在破壞地球環(huán)境的同時,也在毀滅著自己。人類只有一個地球,尊重地球就是尊重生命,拯救地球就是拯救未來。4月22日(也就是明天)是“世界地球日”,全球各地的環(huán)保人士和團體都在舉辦形形色色的紀念地球日環(huán)保活動。然而,愛護地球,保護地球絕不應是止于一朝一夕,一舉一動的象征性行為?!暗厍蛉铡敝荒茏鳛橐环N標志,在一年中的某一天提醒人們要記得,這個地球已經很脆弱。只有所有的人都能自覺約束自己,都愿齊心協(xié)力地為保護地球而努力,我們的家園才會有希望,我們的明天才能越來越美好。 作為中學生的我們,該如何做呢?

    新知探究前面我們研究了兩類變化率問題:一類是物理學中的問題,涉及平均速度和瞬時速度;另一類是幾何學中的問題,涉及割線斜率和切線斜率。這兩類問題來自不同的學科領域,但在解決問題時,都采用了由“平均變化率”逼近“瞬時變化率”的思想方法;問題的答案也是一樣的表示形式。下面我們用上述思想方法研究更一般的問題。探究1: 對于函數(shù)y=f(x) ,設自變量x從x_0變化到x_0+ ?x ,相應地,函數(shù)值y就從f(x_0)變化到f(〖x+x〗_0) 。這時, x的變化量為?x,y的變化量為?y=f(x_0+?x)-f(x_0)我們把比值?y/?x,即?y/?x=(f(x_0+?x)-f(x_0)" " )/?x叫做函數(shù)從x_0到x_0+?x的平均變化率。1.導數(shù)的概念如果當Δx→0時,平均變化率ΔyΔx無限趨近于一個確定的值,即ΔyΔx有極限,則稱y=f (x)在x=x0處____,并把這個________叫做y=f (x)在x=x0處的導數(shù)(也稱為__________),記作f ′(x0)或________,即

    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
