    二、多與病人溝通  在工作中醫(yī)患關系主要是溝通不及時,溝通少造成的,為了避免不必要的事情發(fā)生,在給病人治療之前,診斷之前,會提前與病人做好溝通,與病人家屬做好協(xié)商,得到病人同意之后我們才會采取行動,如果病人或者其家屬不同意,我們也會給出合理的建議,當然都會站在病人的角度去考慮問題,去為病人思考而不是私自做主,雖然我們想要及時給病人治病及時給他們幫助,但是病人自己的意見和家屬的意見一樣很重要?! ⊥瑫r對所有的病人都一視同仁,尊重病人,也會善待病人,減少與病人的沖入,在與病人相處的時候多尊重病人,不因為病人患有各種疑難疾病而對病人有明顯的歧視行為,一切都以病人的健康為主,溝通是建立在彼此尊重的基礎上,彼此要相互體諒,把溝通做好,也要重視,不能制作一個不知聲的人,這樣對于病人,對于家屬都不好,想要做好就要給他們更多的幫助,潤物細無聲,做要做的好,做的細致。

    2學情分析可以說動漫卡通一直伴隨著孩子們的成長,每個孩子都十分喜愛看動漫卡通,尤其是現(xiàn)在的兒童更是在動漫卡通世界里成長的一代,所以學生對動漫卡通形象并不陌生。本課通過大量學生喜歡的動漫卡通形象的欣賞,掌握動漫卡通畫形象的創(chuàng)作表現(xiàn)方法。3重點難點教學重點:感受動漫卡通形象靈動多變的造型之美,并體會創(chuàng)作的樂趣。教學難點:利用學到的知識,進行動漫卡通形象表現(xiàn)。

    自主探究法:教學中強調以學生為主體,強調學生參與知識的形成過程,始終做到為學生提供充足的學習素材、創(chuàng)設充分學習的空間、時間,讓學生自主探究,體驗知識形成的過程,培養(yǎng)主動探究的能力。觀察法:例1觀察物體教學中的觀察是很好的學習方法。例如,教學例1時,觀察目的明確。教師通過讓學生觀察長方體物體學會從不同角度觀察物體的方法。這一安排不僅給學生獨立思考的機會,而且教給學生觀察的思維方法。四、說教學程序在提出問題中,引發(fā)學生思考;在自主探索中,激發(fā)學生創(chuàng)新思維;在展示交流中,感受學生的個性;在總結陳述中,體驗成功的樂趣;在聯(lián)想記憶中進一步發(fā)揮學生的創(chuàng)造才能。在設計這節(jié)課時,我在尊重教材的基礎上,力求體現(xiàn)新課標的新理念、新思想,導學案中設計了以下幾個教學環(huán)節(jié):

    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

    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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?

    分別算出2008年比2007年各季度增產的百分數和合計數,再制成統(tǒng)計表.分析:根據題目要求,要算出各季度增產的百分數,我們只要根據2008年與2007年各個季度的原始數據,運用“求一個數是另一個數的百分之幾”的方法就可以算出.算出了各個季度增產的百分數,根據題意制統(tǒng)計表時,既要按照季度分類,又要反映出年份的類別,所以在確定表頭時可分為3部分:年份、臺數、季度,年份又分為2007年產量、2008年產量、2008年比2007年增產的百分數.2、田力化肥廠今年第一季度生產情況如下:元月份計劃生產1500噸,實際生產1620噸;二月計劃生產1600噸,實際生產1680噸;三月份計劃生產1640噸,實際生產1720噸,根據上面的數據,算出各月完成計劃的百分數,并制成統(tǒng)計表.(1)制作含有百分數的統(tǒng)計表時,百分數這一欄一定要寫清楚是誰占誰的百分之幾,并按“求一個數是另一個數的百分之幾”的解題方法正確算出對應百分數”
