加强对运动员的思想政治工作和对学校环境卫生整治,努力为训练创造一个优良的环境。学校领导有专人分管运动员的思想政治工作,还为女运动员配备了专职的女教师;对家庭比较困难又能刻苦训练、运动成绩比较突出的运动员,向体育局申请给予生活费减免。今年以来,我们还对运动员的身体健康高度重视,确保训练中不发生人身安全事故。学生和家长对我校的管理比较满意。今年,有9位学生家长主动要求我校为他们的子女办理休学手续,以安心在校训练,备战省十一运会。

于是我马上说:“这个问题提得好,又有趣,哪一个同学能回答?”有几个同学先后举手。“方仲永的父亲不让他学习,拉着他到处访问人,四处赚钱,我想他心里一定非常恨他的父亲。” “他父亲拉着仲永四处拜谒,同县人都赞不绝口,仲永心里一定很高兴,以为自身很了不起。”我看同学们的回答都有道理,便立即给予肯定、褒扬。“要是你们是方仲永,心里会怎样想?”

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
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
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?
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.

本节课开始时,首先由一个要在一块长方形木板上截出两块面积不等的正方形,引导学生得出两个二次根式求和的运算。从而提出问题:如何进行二次根式的加减运算?这样通过问题指向本课研究的重点,激发学生的学习兴趣和强烈的求知欲望。本节课是二次根式加减法,目的是探索二次根式加减法运算法则,在设计本课时教案时,着重从以下几点考虑:1.先通过对实际问题的解决来引入二次根式的加减运算,再由学生自主讨论并总结二次根式的加减运算法则。2.四人小组探索、发现、解决问题,培养学生用数学方法解决实际问题的能力。3.对法则的教学与整式的加减比较学习。在理解、掌握和运用二次根式的加减法运算法则的学习过程中,渗透了分析、概括、类比等数学思想方法,提高学生的思维品质和兴趣。
1.会用二次根式的四则运算法则进行简单地运算;(重点)2.灵活运用二次根式的乘法公式.(难点)一、情境导入下面正方形的边长分别是多少?这两个数之间有什么关系,你能借助什么运算法则或运算律解释它?二、合作探究探究点一:二次根式的乘除运算【类型一】 二次根式的乘法计算:(1)3×5; (2)13×27;(3)2xy×1x; (4)14×7.解:(1)3×5=15;(2)13×27=13×27=9=3;(3)2xy×1x=2xy×1x=2y;(4)14×7=14×7=72×2=72.方法总结:几个二次根式相乘,把它们的被开方数相乘,根指数不变,如果积含有能开得尽方的因数或因式,一定要化简.【类型二】 二次根式的除法计算a2-2a÷a的结果是()A.-a-2 B.--a-2C.a-2 D.-a-2解析:原式=a2-2aa=a(a-2)a=a-2.故选C.
