    教师代表大会讲话发言稿

    第一,多理解。让我们在选择后多理解。~~年前,我和现在许多刚毕业的年轻同事一样,带着各种情绪选择了教育这个行业,也带着憧憬和激情来到这里。弹指一挥间,我已跨入中年的行列,变成了传说中的老教师,经历了和大家一样的酸甜苦辣后,我慢慢理解了教师这份职业的意义之所在。由鲜花和掌声、关注与期待交织在一起的教师节,使更多的人把热情与尊重,理解与关怀的目光投向了我们,使我们和学生一起渡过的每一个平凡的日日夜夜有了更加不寻常的意义。身为教师,我们也曾有年轻气盛的躁动和桃李满园的欣喜;也曾有屡遭误解的痛楚和不眠不休的焦虑。但,从把教师作为一种职业,到把教师当作一种理想与事业的追求,一种挑战自我、完善自我的方式,其间的过程,苦乐自知。

    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.

    ⑦在我看来, 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.

    三、科学育人抓质量不是只抓课本知识,而是要从抓习惯、抓细节、抓学困生、抓读书等方面入手。抓质量要从培养学生良好的学习习惯入手,良好习惯的培养,只靠班主任一人是心有余而力不足的,需要每一位教师齐心协力,齐抓共管。抓质量要注重细节,如语文要从生字、背诵开始夯实基础,数学要从基本计算、每一个小知识点、读题审题点滴落实。抓好每个细节,进而形成习惯,学生的成绩自然就会提高。抓质量要把目光投向学困生,如课堂上设计一些学困生能够回答上来的问题并及时表扬他们,不断增强自信,课后适当开“小灶”,加强指导,还要跟踪辅导,持续关注,增强他们的学习主动性和积极性,成绩也会有提高。抓质量还要抓读书,要培养学生的读书兴趣,让读书成为学生的生活方式,不仅课上读,还要在课外读,不仅让学生读,教师自己更要读。

    由样本相关系数??≈0.97,可以推断脂肪含量和年龄这两个变量正线性相关,且相关程度很强。脂肪含量与年龄变化趋势相同.归纳总结1.线性相关系数是从数值上来判断变量间的线性相关程度,是定量的方法.与散点图相比较,线性相关系数要精细得多,需要注意的是线性相关系数r的绝对值小,只是说明线性相关程度低,但不一定不相关,可能是非线性相关.2.利用相关系数r来检验线性相关显著性水平时,通常与0.75作比较,若|r|>0.75,则线性相关较为显著,否则不显著.例2. 有人收集了某城市居民年收入(所有居民在一年内收入的总和)与A商品销售额的10年数据,如表所示.画出散点图,判断成对样本数据是否线性相关,并通过样本相关系数推断居民年收入与A商品销售额的相关程度和变化趋势的异同.
