三、孟德尔遗传规律的现代解释①分离定律：在杂合体的细胞中，位于一对同源染色体上的等位基因，具有一定的独立性；在减数分裂形成配子的过程中，等位基因随同源染色体的分开而分离，独立地随配子遗传给后代。②自由组合定律：位于非同源染色体上的非等位基因的分离或组合是互不干扰的；在减数分裂过程中，同源染色体的等位基因彼此分离的同时，非同源染色体上的非等位基因自由组合。总结：再次强调孟德尔遗传定律的现代解释课堂练习：书本31页6、教学反思：本节课设置了一系列问题情境，层层设问，在学生答问、质疑、讨论过程中让学生建构新概念和新的知识体系，并通过教师及时掌握反馈信息，适时点拨、调节，让学生在推理判断中培养良好的思维习惯和对知识的迁移能力，而且通过留出一定的时间让学生提问，体现了以学生为主体的思想。

篮球教练年度个人工作总结范文多篇
一、“准确、快速、灵活”的意义及其关系。 “准确”是篮球运动中的一个突出矛盾，通常在比赛中因传球准确性差造成很多失误，或因投篮不准带来比赛的失败。篮球比赛本身攻守双方一切技术、战术的应用和对抗的焦点就是围绕解决能否干扰对方的一切行动的准确性并争取自己尽量多把球投入对方篮圈，因此，不难看出“准确”的重要。 快速”的目的是为了出其不意，攻其不备，可以造成以多打少；“灵活”是随机应变，克服不利条件，争取有利局势，没有“快”就没有“灵活”，“快”与“灵”为“准确”创造条件，保证“准确”的发挥，“快”与“活”是手段，“准确”是目的，反之，“准确”的动作缩短了时间，争取了速度，“准确”的投篮又逼使对方扩大防区，而对方防区的扩大，更有利发挥“灵活”和“快速”的特长。由此可见，“准确”是三者核心，应占首位。 二、在篮球队训练中的运用 我一直担任校男篮教练工作，通过几年来的实践，我在训练比赛中注意贯彻“准确、快速、灵活”这一指导思想，取得了显著的成绩。我校男篮在参加市级比赛中，多年保持前几名的地位。

人教版高中历史必修3西方人文主义思想的起源说课稿
苏格拉底把装有毒酒的杯子举到胸口，平静地说：“分手的时候到了，我将死，你们活下来，是谁的选择好，只有天知道。”说毕，一口喝干了毒酒。（2） 苏格拉底临死前对一个叫克力同的人说了这样一番话。克力同，我告诉你，这几天一直有一个神的声音在我心中晓喻我，他说：“苏格拉底，还是听我们的建议吧，我们是你的卫士。不要考虑你的子女、生命或其他东西胜过考虑什么是公正。……事实上你就要离开这里了。当你去死的时候，你是个牺牲品，但不是我们所犯错误的牺牲品，而是你同胞所犯错误的牺牲品。但你若用这种可耻的方法逃避，以错还错，以恶报恶，践踏你自己和我们订立的协议合约，那么你伤害了你最不应该伤害的，包括你自己、你的朋友、你的国家，还有我们。到那时，你活着面对我们的愤怒，你死后我们的兄弟、冥府里的法律也不会热情欢迎你；因为它们知道你试图尽力摧毁我们。别接受克力同的建议，听我们的劝告吧。”

出佛手园，远处有山，山中有岚，有云。岚清，云白，绸缎一般，棉花一般，曼妙而行，逍遥自在。除了爱，还有眼前这山川草木。小小人类身处自然，永不孤单。那些草木，那些动物，那些自然界中的生灵，各安其所，相处自洽。而人类，不免焦虑，屡屡焦虑，内在小宇宙紊乱，何不走到自然中，谦卑蹲下，去学习一株草、一颗露珠的宁静？
人音版小学音乐四年级下册我是少年阿凡提说课稿
紧接着是升记号的认识。在这里我把升记号介绍给学生，教师先用电子琴演奏没有升记号的乐句，再演奏有升记号的乐句，学生听一听那一个音有变化。然后教师再分别把单独的有变化的一个音拿出来进行比较，最后用键盘图在幻灯片上展示。使学生更直观的去听去感受，使学生听觉与视觉互补。增强学生的参与意识，使复杂乏味枯燥的音乐知识变的趣味化，生动化，通过师生的共同参与，更加拉近了教师与学生的距离。最后是编创与活动.由于这首歌是以环保为主题，所以我用音乐与环境保护有机结合的融合，从而进行德育渗透，通过生生合作、和自主探究的方式来进行编创歌词。最后让学生用载歌载舞的形式表现歌曲.依托音乐本身的魅力培养学生主动学习，合作意识，探究精神，从目标的提出到过程的安排，学习方法的确定乃至学习成果的呈现，都让学生有更大的自主性，更多的实践性，更浓的创造性。

师：在科学发展过程中，前一个理论体系的不完善之处，往往是新的研究和新的发现的突破口。开普勒之后，意大利天文学家伽利略创制了天文望远镜，用更加精确的观察继续发展和验证哥白尼创立的新天文学理论。除了用望远镜进行天文观察以外，伽利略还开始进行自然科学的实验研究，哪位同学能给大家讲一讲伽利略在比萨斜塔上所作的关于物体自由下落的实验？生：（讲述这一实验）师：所以，伽利略在科学方面更加重要的贡献是奠定了近代实验科学的基础。（2）实验科学和唯物主义师：伽利略从实践上开辟了实验科学的方法，而英国唯物主义哲学家培根则从理论上阐述了实验科学的方法——归纳法。培根和伽利略同被称为实验科学之父，培根还有一句影响深刻的名言：“知识就是力量”，表明了他注重知识，尊崇科学的精神。我们再来概括一下意大利哲学家布鲁诺的唯物主义思想，是否有同学可以简述布鲁诺的生平事迹？

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.
