人教A版高中數(shù)學(xué)必修一正弦函數(shù)、余弦函數(shù)的圖像教學(xué)設(shè)計(jì)（2）
由于三角函數(shù)是刻畫(huà)周期變化現(xiàn)象的數(shù)學(xué)模型，這也是三角函數(shù)不同于其他類型函數(shù)的最重要的地方，而且對(duì)于周期函數(shù)，我們只要認(rèn)識(shí)清楚它在一個(gè)周期的區(qū)間上的性質(zhì)，那么它的性質(zhì)也就完全清楚了，因此本節(jié)課利用單位圓中的三角函數(shù)的定義、三角函數(shù)值之間的內(nèi)在聯(lián)系性等來(lái)作圖，從畫(huà)出的圖形中觀察得出五個(gè)關(guān)鍵點(diǎn)，得到“五點(diǎn)法”畫(huà)正弦函數(shù)、余弦函數(shù)的簡(jiǎn)圖．課程目標(biāo)1.掌握“五點(diǎn)法”畫(huà)正弦曲線和余弦曲線的步驟和方法，能用“五點(diǎn)法”作出簡(jiǎn)單的正弦、余弦曲線.2.理解正弦曲線與余弦曲線之間的聯(lián)系. 數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：正弦曲線與余弦曲線的概念； 2.邏輯推理：正弦曲線與余弦曲線的聯(lián)系； 3.直觀想象：正弦函數(shù)余弦函數(shù)的圖像； 4.數(shù)學(xué)運(yùn)算：五點(diǎn)作圖； 5.數(shù)學(xué)建模：通過(guò)正弦、余弦圖象圖像，解決不等式問(wèn)題及零點(diǎn)問(wèn)題，這正是數(shù)形結(jié)合思想方法的應(yīng)用.

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.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. 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!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.
