抛物线的简单几何性质（2）教学设计人教A版高中数学选择性必修第一册
二、直线与抛物线的位置关系设直线l:y=kx+m,抛物线:y2=2px(p>0),将直线方程与抛物线方程联立整理成关于x的方程k2x2+2(km-p)x+m2=0.(1)若k≠0,当Δ>0时,直线与抛物线相交,有两个交点;当Δ=0时,直线与抛物线相切,有一个切点;当Δ<0时,直线与抛物线相离,没有公共点.(2)若k=0,直线与抛物线有一个交点,此时直线平行于抛物线的对称轴或与对称轴重合.因此直线与抛物线有一个公共点是直线与抛物线相切的必要不充分条件.二、典例解析例5.过抛物线焦点F的直线交抛物线于A、B两点，通过点A和抛物线顶点的直线交抛物线的准线于点D，求证：直线DB平行于抛物线的对称轴．【分析】设抛物线的标准方程为：y2＝2px（p＞0）．设A（x1，y1），B（x2，y2）．直线OA的方程为： ＝ ＝ ，可得yD＝ ．设直线AB的方程为：my＝x﹣ ，与抛物线的方程联立化为y2﹣2pm﹣p2＝0，

人教版新课标高中物理必修1速度变化快慢的描述─加速度说课稿2篇
本来比较速度变化的快慢也有两种方法：一种是比较相同时间内速度变化量的大小；另一种是比较发生相同的速度变化所需要的时间长短。但教材是将比较质点位置移动快慢的思想直接迁移过来，通过实例分析，使学生明白不同运动物体的速度变化快慢不同，表现在速度的变化与发生这个变化所用时间的比值不同，从而引入加速度的定义方法a=△v/△t。加速度表示速度的变化快慢，包括速度增加的快慢和减小的快慢，不能误认为只要有加速度的运动速度就一定是增加的。广义地讲，加速度不仅可以描述速度大小的变化快慢，而且也可以描述速度方向变化的快慢，本节教材只限定在直线运动的情景中讨论。加速度的矢量性是一个难点，教材是以与速度方向相同或是相反来表述加速度的矢量性的。如果以初速度方向为正方向，那么加速度就有正负之分，加速度的正负表示加速度的方向，不表示加速度的大小。
人教版新课标高中物理必修1探究小车速度随时间变化的规律说课稿2篇
（三）合作交流能力提升教师：刚才我们通过实验了解了小车的速度是怎样随时间变化的，但实验中有一定的误差，请同学们讨论并说出可能存在哪些误差，造成误差的原因是什么？（每个实验小组的同学之间进行热烈的讨论）学生：测量出现误差。因为点间距离太小，测量长度时容易产生误差。教师：如何减小这个误差呢？学生：如果测量较长的距离，误差应该小一些。教师：应该采取什么办法？学生：应该取几个点之间的距离作为一个测量长度。教师：好，这就是常用的取“计数点”的方法。我们应该在纸带上每隔几个计时点取作一个计数点，进行编号。分别标为：0、1、2、3……，测各计数点到“0”的距离。以减小测量误差。教师：还有补充吗？学生1：我在坐标系中描点画的图象只集中在坐标原定附近，两条图象没有明显的分开。学生2：描出的几个点不严格的分布在一条直线上，还能画直线吗？
人教版高中历史必修2战后资本主义世界经济体系的形成说课稿3篇
1、《战后资本主义世界经济体系的形成》是人教版高中历史必修Ⅱ第八单元第22课，学时为1课时。《历史必修Ⅱ》一书用古今贯通、中外关联的八个专题来着重反映人类社会经济和社会生活领域发展进程中的重要史实。从第一单元勾勒“古代中国经济的基本结构与特点”再到第八单元“世界经济的全球化趋势”，以历史唯物主义观点清晰阐明经济全球化是世界生产力发展的要求和结果，是不以人的意志为转移的历史必然趋势。第八单元的标题是《世界经济的全球化趋势》，作为最后一单元，从内容上讲，有强烈的时代感和现实意义，是全书内容的总结与升华展望。提起“全球化”这个十年前才首次出现在美国《商业周刊》的新名词，如今却是地球人都知道了。然而究竟什么是全球化？作为一历史现象，全球化有其自身内部严密完整的体系，其中核心之一便是制度、规则的全球化，而这正是本课内容的着力点。

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.

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
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:● …horse 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.
