本課是高中數(shù)學(xué)第一章第4節(jié)，充要條件是中學(xué)數(shù)學(xué)中最重要的數(shù)學(xué)概念之一， 它主要討論了命題的條件與結(jié)論之間的邏輯關(guān)系,目的是為今后的數(shù)學(xué)學(xué)習(xí)特別是數(shù)學(xué)推理的學(xué)習(xí)打下基礎(chǔ)。從學(xué)生學(xué)習(xí)的角度看，與舊教材相比，教學(xué)時間的前置，造成學(xué)生在學(xué)習(xí)充要條件這一概念時的知識儲備不夠豐富，邏輯思維能力的訓(xùn)練不夠充分，這也為教師的教學(xué)帶來一定的困難．“充要條件”這一節(jié)介紹了充分條件,必要條件和充要條件三個概念,由于這些概念比較抽象,中學(xué)生不易理解,用它們?nèi)ソ鉀Q具體問題則更為困難,因此”充要條件”的教學(xué)成為中學(xué)數(shù)學(xué)的難點之一,而必要條件的定義又是本節(jié)內(nèi)容的難點.A.正確理解充分不必要條件、必要不充分條件、充要條件的概念；B.會判斷命題的充分條件、必要條件、充要條件．C.通過學(xué)習(xí)，使學(xué)生明白對條件的判定應(yīng)該歸結(jié)為判斷命題的真假.D.在觀察和思考中，在解題和證明題中，培養(yǎng)學(xué)生思維能力的嚴密性品質(zhì)．

(4)“不論m取何實數(shù),方程x2+2x-m=0都有實數(shù)根”是全稱量詞命題,其否定為“存在實數(shù)m0,使得方程x2+2x-m0=0沒有實數(shù)根”,它是真命題.解題技巧：（含有一個量詞的命題的否定方法）(1)一般地,寫含有一個量詞的命題的否定,首先要明確這個命題是全稱量詞命題還是存在量詞命題,并找到其量詞的位置及相應(yīng)結(jié)論,然后把命題中的全稱量詞改成存在量詞,存在量詞改成全稱量詞,同時否定結(jié)論.(2)對于省略量詞的命題,應(yīng)先挖掘命題中隱含的量詞,改寫成含量詞的完整形式,再依據(jù)規(guī)則來寫出命題的否定.跟蹤訓(xùn)練三3．寫出下列命題的否定,并判斷其真假:(1)p:?x∈R,x2-x+ ≥0;(2)q:所有的正方形都是矩形;(3)r:?x∈R,x2+3x+7≤0;(4)s:至少有一個實數(shù)x,使x3+1=0.【答案】見解析【解析】(1) p:?x∈R,x2-x+1/4<0.∵?x∈R,x2-x+1/4=(x"-" 1/2)^2≥0恒成立,∴ p是假命題.

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)過點B與直線a有且僅有一個平面α，因此平面平面α與β重合，從而 , 進而A∈α，這與A?α矛盾。所以直線AB與a是異面直線。補充說明：例二告訴我們一種判斷異面直線的方法：與一個平面相交的直線和這個平面內(nèi)不經(jīng)過交點的直線是異面直線。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)．

問題導(dǎo)入：問題一：試驗1：分別拋擲兩枚質(zhì)地均勻的硬幣，A=“第一枚硬幣正面朝上”，B=“第二枚硬幣正面朝上”。事件A的發(fā)生是否影響事件B的概率？因為兩枚硬幣分別拋擲，第一枚硬幣的拋擲結(jié)果與第二枚硬幣的拋擲結(jié)果互相不受影響，所以事件A發(fā)生與否不影響事件B發(fā)生的概率。問題二：計算試驗1中的P(A),P(B),P(AB)，你有什么發(fā)現(xiàn)？在該試驗中，用1表示硬幣“正面朝上”，用0表示“反面朝上”，則樣本空間Ω={（1，1），（1，0），（0，1），（0，0）}，包含4個等可能的樣本點。而A={（1，1），（1，0）}，B={（1，0），（0，0）}所以AB={（1，0）}由古典概率模型概率計算公式，得P(A)=P(B)=0.5，P(AB)=0.25， 于是 P(AB)=P(A)P(B)積事件AB的概率恰好等于事件A、B概率的乘積。問題三：試驗2：一個袋子中裝有標號分別是1，2，3，4的4個球，除標號外沒有其他差異。

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.
