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.

新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學設計二
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.

在主題教育專題學習班總結(jié)會上的講話
正如所說，一個人廉潔自律不過關(guān)，做人就沒有骨氣。近幾年，D中央和各級進一步加大反腐力度，XX系統(tǒng)也查處了一大批案件，從案件來看有的是“小掀大浪”，有的是“小浪翻大”，有的是“剛靠岸人落水”，其違法違紀的原因雖然很多，但缺乏防腐定力，是一個非常重要的原因。作為中層干部，大家都是后起之秀，在單位里是骨干，受人尊重；在家里是頂梁柱，父母因為我們而榮耀，家屬因為我們而自豪，子女因為我們而驕傲，如果把持不住觸犯了法律，雖然犯錯的是自己，但傷害的卻是整個家庭。希望在座的各位對法紀心存敬畏，時刻保持“如履薄冰”的警覺，從小事小節(jié)上守起，正心明道、懷德自重，勤撣“思想塵”、多思“貪欲害”、常破“心中賊”，守住政治關(guān)、權(quán)力關(guān)、交往關(guān)、生活關(guān)、親情關(guān)，扣好廉潔從政的“第一?？圩印?，永葆清正廉潔的政治本色。

在中學2023屆高三級高考倒計時動員大會上的講話
各位老師、同學們，大家晚上好！時光荏苒，歲月不居；深秋尚未央，初冬已登場。在這黃花照暖陽的初冬美好日子，我們在**六中大禮堂隆重集會，召開****屆高三倒計時動員大會，為高三級師生決勝高考、創(chuàng)造輝煌鼓勁加油。在此，我代表**六中全體師生向今天獲得表彰的**等***名同學及高三*班等**個優(yōu)秀班集體表示熱烈的祝賀，向大家致以最美好的祝愿，祝愿****圓滿成功、金榜題名！同學們、老師們，十年磨一劍，一朝顯鋒芒。今天，距****年高考僅有***天，高考報名工作即將完成。冬已臨，春將至，從現(xiàn)在開始，我們已經(jīng)進入到了高考時間，我們的逐夢征程已邁上了沖刺線，我們的奮進人生路踏上了關(guān)鍵拼搏點。奮斗的人生四季如歌，拼搏的生命精彩璀璨，同學們，高三是拼搏的高三，高三是沖刺的高三，高三是奮斗人生的高三，高三是奮斗人生中最值得、最需要付出的一段。在這個關(guān)鍵節(jié)點，在今天動員大會上，我向大家提出以下幾點希望：
在全鎮(zhèn)教學能手大賽總結(jié)會上的講話
三、科學育人抓質(zhì)量不是只抓課本知識，而是要從抓習慣、抓細節(jié)、抓學困生、抓讀書等方面入手。抓質(zhì)量要從培養(yǎng)學生良好的學習習慣入手，良好習慣的培養(yǎng)，只靠班主任一人是心有余而力不足的，需要每一位教師齊心協(xié)力，齊抓共管。抓質(zhì)量要注重細節(jié)，如語文要從生字、背誦開始夯實基礎，數(shù)學要從基本計算、每一個小知識點、讀題審題點滴落實。抓好每個細節(jié)，進而形成習慣，學生的成績自然就會提高。抓質(zhì)量要把目光投向?qū)W困生，如課堂上設計一些學困生能夠回答上來的問題并及時表揚他們，不斷增強自信，課后適當開“小灶”，加強指導，還要跟蹤輔導，持續(xù)關(guān)注，增強他們的學習主動性和積極性，成績也會有提高。抓質(zhì)量還要抓讀書，要培養(yǎng)學生的讀書興趣，讓讀書成為學生的生活方式，不僅課上讀，還要在課外讀，不僅讓學生讀，教師自己更要讀。
在2023年關(guān)于學習貫徹主題教育的點評總結(jié)講話
同時，要結(jié)合整改做好“預防文章”，突出抓早抓小，完善各項規(guī)章制度，把紀律挺在前面，強化制度的剛性約束，切實把專題學習貫徹新時代中國特色社會主義思想ZT教育的成果轉(zhuǎn)化為指導工作實踐的有力武器。三是嚴守紀律規(guī)矩，保持勤政廉潔。身邊的反面典型就是最好的警示，大家要深刻汲取XX嚴重違紀違法案件教訓，深刻認識到失責必問、問責必嚴已經(jīng)成為常態(tài)。要堅決扛起全面從嚴治D的政治責任，嚴格落實“一崗雙責”，營造風清氣正的政治生態(tài)。要牢固樹立法紀意識，嚴守政治紀律和政治規(guī)矩。要樹立正確的權(quán)力觀、政績觀、事業(yè)觀，嚴把小事、守好小節(jié)，管好家人、樹好家風，遠離“圈子”、防止“圍獵”，始終做到崇廉拒腐，干凈做事。最后，希望XX班子團結(jié)帶領(lǐng)XXD員干部群眾堅持發(fā)展為先、實干為要，緊盯目標任務，奮力比學趕超，積極爭先進位，有序推進年度各項工作，交出一份優(yōu)異的答卷。
