我將根據(jù)新的語文能力實(shí)踐系統(tǒng)，致力于學(xué)生語文綜合素質(zhì)的提高，促進(jìn)語文課程的呈現(xiàn)方式和學(xué)生學(xué)習(xí)方式的轉(zhuǎn)變，確立學(xué)生在學(xué)習(xí)中的主體地位，努力給學(xué)生創(chuàng)造一個有利于素質(zhì)教育的空間?！ τ谛W(xué)語文教學(xué)來說，既要轉(zhuǎn)變教的方式又要轉(zhuǎn)變學(xué)的方式，培養(yǎng)和形成“自主、合作、探究”的學(xué)習(xí)方式，在這兩個轉(zhuǎn)變中，教的方式轉(zhuǎn)變是主要矛盾。教的方式一轉(zhuǎn)變，學(xué)的方式也隨之轉(zhuǎn)變。學(xué)的方式轉(zhuǎn)變可以理情地在課堂中呈現(xiàn)，證明教的方式轉(zhuǎn)變，證明教師新理念的真正樹立。課改實(shí)踐告訴我們，沒有堅定的新課程理念，真正意義上的教與學(xué)方式的轉(zhuǎn)變是不可能的。把課標(biāo)學(xué)習(xí)與教材教法研究結(jié)合起來：要鉆研新教材，理解和把握新教材，用好新教材，要重視教學(xué)反思，個案研究和收集，要牢記驗(yàn)證課標(biāo)和檢驗(yàn)教材的實(shí)驗(yàn)任務(wù)。

第一：導(dǎo)課。在這個環(huán)節(jié)中，首先對學(xué)生提出《課堂常規(guī)》要求，以對口令、比一比的形式，讓學(xué)生了解《常規(guī)》、遵守《常規(guī)》；再復(fù)習(xí)8、9的組成，為熟練口算掃清障礙。第二：新課。1、結(jié)合情境，引導(dǎo)學(xué)生充分感受“一圖四式”。由于學(xué)生已經(jīng)有了看一幅圖列出兩個算式的基礎(chǔ)，所以列出加法算式相對容易一些，而列出減法算式則是這部分的難點(diǎn)。因此我采用小組合作的方式，讓學(xué)生以看圖說話的方式搜集相關(guān)數(shù)據(jù)，初步感知根據(jù)一幅圖可以列出四道不同的算式。2、在老師的指導(dǎo)下進(jìn)行操作，通過擺蘋果圖使學(xué)生進(jìn)一步鞏固和理解“一圖四式”。在計算過程體現(xiàn)加減法之間的聯(lián)系。3、幫助學(xué)生積累計算方法，為學(xué)生提供創(chuàng)造的空間。直接出示算式5+3、3+5、8-3、8-5計算，提問：你是怎樣算出得數(shù)的？鼓勵學(xué)生說出多種計算方法，使計算方法多樣化（如：數(shù)數(shù)、想數(shù)的組成與分解、調(diào)換加數(shù)的位置、算減法想加法等）。

The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2.

The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

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:● …h(huán)orse 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 topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate.

John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

二、為了保證學(xué)生能夠全員上課，上課點(diǎn)名查學(xué)生到課情況，上課中間會不定時點(diǎn)名提問，結(jié)束時還會再次查到課情況，盡管反復(fù)強(qiáng)調(diào)課堂紀(jì)律，但總有部分學(xué)生不能按時上課，還有1—2個學(xué)生甚至不上課。 三、課后會利用釘釘家校本給學(xué)生布置幾個填空題或完成課堂筆記，鞏固所學(xué)知識。為了保證作業(yè)能夠按時完成，每天利用釘釘?shù)募倚１镜奶嵝鸭议L功能多次提醒家長督促孩子完成作業(yè)，但完成情況不盡如人意，就昨天的作業(yè)檢查情況來看，118班40人，完成36人。116班36人，完成32人。
北師大初中數(shù)學(xué)八年級上冊一次函數(shù)與正比例函數(shù)1教案
煤的價格為400元/噸，生產(chǎn)1噸甲產(chǎn)品除需原料費(fèi)用外，還需其他費(fèi)用400元，甲產(chǎn)品每噸售價4600元；生產(chǎn)1噸乙產(chǎn)品除原料費(fèi)用外，還需其他費(fèi)用500元，乙產(chǎn)品每噸售價5500元．現(xiàn)將該礦石原料全部用完，設(shè)生產(chǎn)甲產(chǎn)品x噸，乙產(chǎn)品m噸，公司獲得的總利潤為y元．(1)寫出m與x的關(guān)系式；(2)寫出y與x的函數(shù)關(guān)系式．(不要求寫自變量的取值范圍)解析：(1)因?yàn)榈V石的總量一定，當(dāng)生產(chǎn)的甲產(chǎn)品的數(shù)量x變化時，那么乙產(chǎn)品的產(chǎn)量m將隨之變化，m和x是動態(tài)變化的兩個量；(2)題目中的等量關(guān)系為總利潤y＝甲產(chǎn)品的利潤＋乙產(chǎn)品的利潤．解：(1)因?yàn)?m＋10x＝300，所以m＝150－5x2.(2)生產(chǎn)1噸甲產(chǎn)品獲利為4600－10×200－4×400－400＝600(元)；生產(chǎn)1噸乙產(chǎn)品獲利為5500－4×200－8×400－500＝1000(元)．所以y＝600x＋1000m.將m＝150－5x2代入，得y＝600x＋1000×150－5x2，即y＝－1900x＋75000.方法總結(jié)：根據(jù)條件求一次函數(shù)的關(guān)系式時，要找準(zhǔn)題中所給的等量關(guān)系，然后求解．
