人教A版高中數(shù)學(xué)必修一等式性質(zhì)與不等式性質(zhì)教學(xué)設(shè)計(jì)（2）
等式性質(zhì)與不等式性質(zhì)是高中數(shù)學(xué)的主要內(nèi)容之一，在高中數(shù)學(xué)中占有重要地位，它是刻畫現(xiàn)實(shí)世界中量與量之間關(guān)系的有效數(shù)學(xué)模型，在現(xiàn)實(shí)生活中有著廣泛的應(yīng)，有著重要的實(shí)際意義.同時(shí)等式性質(zhì)與不等式性質(zhì)也為學(xué)生以后順利學(xué)習(xí)基本不等式起到重要的鋪墊.課程目標(biāo)1. 掌握等式性質(zhì)與不等式性質(zhì)以及推論，能夠運(yùn)用其解決簡(jiǎn)單的問(wèn)題．2. 進(jìn)一步掌握作差、作商、綜合法等比較法比較實(shí)數(shù)的大?。?3. 通過(guò)教學(xué)培養(yǎng)學(xué)生合作交流的意識(shí)和大膽猜測(cè)、樂(lè)于探究的良好思維品質(zhì)。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：不等式的基本性質(zhì)；2.邏輯推理：不等式的證明；3.數(shù)學(xué)運(yùn)算：比較多項(xiàng)式的大小及重要不等式的應(yīng)用；4.數(shù)據(jù)分析：多項(xiàng)式的取值范圍，許將單項(xiàng)式的范圍之一求出，然后相加或相乘.（將減法轉(zhuǎn)化為加法，將除法轉(zhuǎn)化為乘法）；5.數(shù)學(xué)建模：運(yùn)用類比的思想有等式的基本性質(zhì)猜測(cè)不等式的基本性質(zhì)。

1.探究：根據(jù)基本事實(shí)的推論2,3，過(guò)兩條平行直線或兩條相交直線，有且只有一個(gè)平面，由此可以想到，如果一個(gè)平面內(nèi)有兩條相交或平行直線都與另一個(gè)平面平行，是否就能使這兩個(gè)平面平行？如圖（1），a和b分別是矩形硬紙板的兩條對(duì)邊所在直線，它們都和桌面平行，那么硬紙板和桌面平行嗎？如圖（2），c和d分別是三角尺相鄰兩邊所在直線，它們都和桌面平行，那么三角尺與桌面平行嗎？2.如果一個(gè)平面內(nèi)有兩條平行直線與另一個(gè)平面平行，這兩個(gè)平面不一定平行。我們借助長(zhǎng)方體模型來(lái)說(shuō)明。如圖，在平面A’ADD’內(nèi)畫一條與AA’平行的直線EF,顯然AA’與EF都平行于平面DD’CC’,但這兩條平行直線所在平面AA’DD’與平面DD’CC’相交。3.如果一個(gè)平面內(nèi)有兩條相交直線與另一個(gè)平面平行，這兩個(gè)平面是平行的，如圖，平面ABCD內(nèi)兩條相交直線A’C’,B’D’平行。

9.例二：如圖，AB∩α=B,A?α， ?a.直線AB與a具有怎樣的位置關(guān)系？為什么？解：直線AB與a是異面直線。理由如下：若直線AB與a不是異面直線，則它們相交或平行，設(shè)它們確定的平面為β，則B∈β， 由于經(jīng)過(guò)點(diǎn)B與直線a有且僅有一個(gè)平面α，因此平面平面α與β重合，從而 , 進(jìn)而A∈α，這與A?α矛盾。所以直線AB與a是異面直線。補(bǔ)充說(shuō)明：例二告訴我們一種判斷異面直線的方法：與一個(gè)平面相交的直線和這個(gè)平面內(nèi)不經(jīng)過(guò)交點(diǎn)的直線是異面直線。10. 例3 已知a，b，c是三條直線，如果a與b是異面直線，b與c是異面直線，那么a與c有怎樣的位置關(guān)系？并畫圖說(shuō)明．解： 直線a與直線c的位置關(guān)系可以是平行、相交、異面．如圖(1)(2)(3)．總結(jié)：判定兩條直線是異面直線的方法(1)定義法：由定義判斷兩條直線不可能在同一平面內(nèi)．

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 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.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

新人教版高中英語(yǔ)必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計(jì)
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.
