人教版高中语文必修2《想象世界学习虚构》教案2篇
虚构不等于说假话。它是一种源于生活，但高于生活的艺术真实。我们可以举个例子：我国公认的最权威最真实的史书是——《史记》，那么，大家认为《史记》里有没有虚构呢？有。必修一的《鸿门宴》里就有虚构。大家想：司马迁是哪个朝代的人？西汉汉武帝时。刘邦项羽是哪个朝代的？秦末时期。那司马迁不可能坐时光穿梭机到秦末去参加鸿门宴吧？既然他没不在场，那课文《鸿门宴》里人物的语言、动作、甚至是表情从何而来呢？对，是司马迁根据有限的史料加以补充，想象、虚构出来的。那么，同学们在写作文时，也可以不必拘泥于亲身经历的事情，毕竟生活是平淡的，毕竟大家的生活阅历也有限，有时候，我们发挥想象、虚构一个故事来反映生活的真实，也许更生动、也更典型。所以，近年来高考试卷中都提示考生：作文可以大胆想象，编写故事。按照编故事的方式不同，我们的虚构性作文又可以写哪些类型呢：小说，散文，童话，寓言，科幻，故事新编……
人教版高中语文必修3《语文学习的自我评价》教案
一、语文学习中学生自我评价能力的培养1．营造氛围，培养学生自我评价的意识。学生自我评价能力是教师长期培养的结果，而保护学生自我评价的热情，更是持续自我评价的保证。在我们的实际教育教学中，教师一直处于评价的绝对主体，很少去关注学生自我评价意识和能力的培养，学生常常不理解：为什么要认真听讲？为什么书写要工整、为什么发言要积极？为什么老师、父母对考试分数会有那么高的要求？当前出现的学生许多诸如“离家出走”、“毒杀亲人”等教育、行为、品德方面的问题，我想其中除了家长、教师的评价意识和评价艺术等原因之外，学生的自我评价意识的缺乏是根本的原因。所以我认为，学生自我评价意识的培养刻不容缓。（1）热情鼓励，提供成功的心理体验。在教学过程中，教师要善于发现、肯定学生自我评价的点滴进步，对于他们每一点进步都要真诚热情地鼓励。让学生觉得我这么做，这么想是对的。让学生在教师的鼓励中体会到强烈的爱，感受到自己的进步，增强自己的信心。“心若在，梦就在！”教师的热情鼓励是一种强大的催化剂，促使学生在学习中乐于自我评价。

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.

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.
