3、子翻译。【设计意图】利用早自修的时间，让学生熟读课文，准备句子翻译。根据学生水平，为了提高他们的学习积极性以及学习的成就感，有些难一点的句子教师事先给我范围。六、教学片断1）、课堂导入、作业反馈和针对讲评Step1. Lead in and feedback from the homework1). Appreciate an MV of MJs “Earth Song” to arouse students interest as well as introduce the topic.2). Give some feedback from the homework including th
4、e students who did a good job in the homework as wall as the students that made great progress recently.3). List the number of the students that made a mistake in each item and explain the ones they needed, such as Q5, which 25 students chose the wrong answer, as well as Q6,8,10. As the rest questio
5、ns, leave them to the students themselves for discussion.Q1: 7Q6: 29Q2: 8Q7:11Q3: 6Q8:32Q4: 15Q9:18Q5: 25Q10: 39 【设计意图】通过MJ的试听输入，快速导入本单元的话题，激活学生么脑中有关野生动物保护的图示，点燃学生的复习热情，启动愉快的复习心情。其次，表扬与肯定那些在作业中表现优异的，取得进步的，刺激学生的学习动机和学习兴趣。最后，针对作业的统计结果，针对性的讲评作业，提高课堂效率。【课堂实录】T：Good morning, class. Do you have any ideas
6、of the theme of this mv?S: Wildlife protection, animal protection, nature,ect.T: Yes. It seems youve absolutely gotten the main idea, and this is exactly what we are going to talk about today. But before we start, we are gonna analyze the homework left yesterday. Here are the names of students who d
7、id a good job and those are the ones who made progress, lets give them our biggest applause(The names are shown in the ppt). And this is the chart that shows the items that most of you have difficulties. And i gonna explain Q56810, the rest are left for you to get them understood after class, got it
8、?S: Yes. 【思考】复习的目的是什么？是唤醒学生淡忘的知识，恢复相关记忆，并能够持久的记忆，灵活地应用知识，学会全面的思考。 但是，在传统的复习课堂中，教师不加筛选的灌输，学生毫无方向的识记。由于负担重，记忆量大，缺乏方法，学生只能在非语境中死记硬背，待复习课结束，他们真正记得的少之又少，这样，复习的目的根本没有达到。所以，即使是在复习课中，适当有趣生动的导入，会让整节课事半功倍。利用作业的批改，进行详细的反馈，对好的学生，进步的学生进行表扬，提高他们学生英语的动力和兴趣。尤其是对于那些后三分之一的学生，如果他们努力的成果能够被老师肯定，那么无疑他们的自信心会大大增加。最后，批改后的统计
9、，对于教师诊断需求和掌握血清尤为重要，通过统计，教师可以知道哪些知识点学生还是存在问题，那些是利用小组讨论形式可以解决的。2）、回归文本，提炼要点Step2. Translation1).Translate five sentences picked out from the textbook and workbook into English to accumulate materials for writing.2). Analyze these sentences and point out the useful expressions in these sentences.1、它们需要
10、食物，良好的环境以及安全。如果它们的栖息地受到威胁或者不能找到足够的食物，它们的数量会减少。(p25, line1)They need food, a good environment and safety. If their habitat is threatened or they can not find enough food, their numbers may decrease.2、 Daisy一直渴望帮助那些频临灭绝的野生动物。(p26, line1)Daisy had always longed to help endangered species of wildlife.3、
11、因此，为了拯救当地的野生动物，好的措施正在被实施。(p26, line24)So good things are being done here to save local wildlife.4、没有人明确的知道恐龙为什么以及如何在这么短的时间内从地球上消失。(p30, line14)Nobody knows for sure why and how dinosaurs disappeared from the earth in such a short time.5、麋鹿（Milu deer），是一种长着大角的生物, 曾经在中国是很常见的。(p65, line4)The Milu deer,
12、 a species with large horns, used to be common in China long ago.【设计意图】 在学生熟读文章的基础上，老师进行语言点的删选，挑选出重要的句型，词汇进行句子翻译，突破学生不熟悉的词汇和句型，并且为下面的写作奠定语言基础。【课堂实录】T: Ok, so much for the homework. Next, lets cover our everyday routine, translations. Are you ready?S: Yes.T: Good, then ill ask two of you to present t
13、hem on the blackboard.After handing in the excise book, the sentences were shown in the ppt to point out some useful expressions such as long to, know for sure,ect. T: Pay attention to the red word in the sentences and you are required to keep them in your minds and your notebooks. Later, they may h
14、elp you in your writing part. Clear?S: Yes. 【思考】复习应该记什么？记多少？从作业批改，反馈，教师了解了学生的发展需求，定位了学生模糊和淡忘的知识，一方面深入文本，对文章中的语言点进行筛选。一方面，要把学生脑海中的零碎的知识串起来，化整为零，如上述翻译中，将现在进行时的被动语态以及一些常见的考纲词汇相结合，进行有效的复习。3）、创设情境、巩固提升Step3. Practice1). Watch a short video about the overhunting of the macaques for their meat and brains.a
15、ccording to; die out; be killed; hunt; decrease; burst into tears; protect from; income; appreciate; in severe danger; without mercy; in peace2). Fill in the blanks with the words given in the chart to pave for writing.Dear X,It is reported that the macaques(猕猴) are now _. _ a survey carried out rec
16、ently by an influential media, the number of macaques is _ rapidly. In other words, these endangered animals are _.As can be seen from the video, the macaques _ for their meat and brains, which can help the villagers increase their _. The local people, taking their guns, _ the poor creatures _. When
17、 seeing a macaque lying on the ground with blood in its mouth, I can not help_. How cruel the human beings are! We should have lived _ with them with no hunting.What can we do to _ them _being killed by the local people. I would _ it if you can give me some advice. Yours, Xiaoming【设计意图】基于学情，精心创设有关动物
18、保护的情境，通过录像内容填空，让知识从宏观逐步过渡到具体，聚焦视角从面迁移到点，突破重要的考纲词汇，语言点，并且为下面的作文练习做好情境支架针对大量捕杀野生动物的情况，为保护野生动物提出一些有效措施。【课堂实录】T: Now that weve reviewed some useful expressions, its time to put them into practice. Some days before, i received a letter from Xiaoming(a student of my class who is preparing for TOEFL). He s
19、aid he recently had watched a movie and was totally shocked by the scenes. Do you wanna see it?S: Yes.T: So, why the macaques are being killed?S: For their meet and brain.T: Do you want to eat their brain?S: No yes.T: Why no?S: Because they are animals, they have life, and we should be friendly to t
20、hem.T: Why yes?S: I think they are delicious.T: Ok, i see. Here is the letter of Xiaomings, lets see what he thinks about it. Please choose the words and fill in the blanks.【反思】复习课中，如何处理语言输入与输出的关系？语言输入要充足，并且形式要多样，更为重要的是，语言的输入为的是最后的输出。在前面几个环节中，教师用不同形式，对学生进行语言的输入：练习讲解，翻译以及选词填空。而且，所有的输入均是围绕野生动物保护这一话题，与
21、最后输出的作文遥相呼应，体现了为用而教，为用而学的理念。4）、联合实践、综合应用Step4. Writing 1). Write an writing about how to protect endangered animals and then share with others.Writing: Help Xiaoming figure out some solutions to protect the Macaques, and many aspects can be included, such as in terms of our government, medium; indiv
22、iduals, ect. Please try you best to use what we have learnt before.2). Writing directionsTips:for the government: make laws to; set up legal organizationsfor the medium: give the public some latest news about the endangered animals; make the illegal hunting uncoveredfor the individuals: be an educat
23、or; take care of the endangered animals around usHere are some useful expressions: hunt; species; protectfrom; in danger, in peace; pay attention to; affect; succeed; die out; reserve; come into being; wildlife protection, it is high time that3). Show out some students outcomes in class and make an
24、assessment.【设计意图】让学生在真实的语境中应用内化了的知识完成最终的写作，培养学生的综合语言应用能力，发展个性化思维。【课堂实录】T: You see, xiaomings asking you for help. Its your time to give him a hand. Do i have any volunteers to write it on the blackboard?Three students put up their hands and write the articles on the blackboardAfter about 10 minutes,
25、 three articles were analysed one by one and strengths were praised and weaknesses were modified. After class, all of the articles were handed in and checked by the teacher. Here are two articles. 【思考】从两篇当堂作文中，我们可以看出，开始的翻译练习中出现的表达，包括their habitat is threatened; are being done; endangered animals 等，学
26、生在写作中都可以应用。随后选词填空中出现的 in peace; be in danger; protect from等词汇也在作文中有所体现，包括定语从句，这说明了学生的对本节课所复习的重点词汇，句型等有了一定掌握，能学以致用。那么，我们复习的要求也就达到了。四、反思用是复习的起点，也是复习的终点，如果一味的讲练，或者一味的灌输而没有应用，复习会事倍功半，学生对英语的热情和兴趣也会缩减。复习的目的是为了用，那如何提高用的效率，一直是我们在探讨的问题。在本案例中，各个环节都与用相关，分别体现在：学生在观看视频中走进动物保护话题，教师通过作业反馈、讲评，创设积极和谐的课堂环境，诊断学生的发展需求，了解学生原有知识的状况；通过回归文本，翻译句子，教师筛选语言要点，消除语言盲点；接下来再次通过视频，创设语言情境，搭设支架，学习和应用考纲重点词汇，达到巩固语言和内化语言的目的；最后，学生用积累的语言来解决实际的问题，学以致用。8
