3、tended answer by providing some examples so that students can be led to the answer “By using prefixes and suffixes” or by “cloning it” (just for fun).Explanation鉴于学生已有比较长时间的学习英语的经历，前后缀对于他们来说并不陌生。以让他们总结如何让自己词汇量加倍这一方法开始整堂课的教学，从开放的问题到焦点的关注，从悬念到平实，让学生在瞬间产生好奇，并且在答案揭晓的刹那能很好得活跃课堂气氛，为后面的教学做好铺垫。Step 2 Prefix
4、es and suffixes (PPT6-10)1. Brainstorming. Ask students to list as many prefixes and suffixes as possible and write them down on the blackboard. Their answers can be more than what are listed on Pag e 46. If anyt hing is left out, its teachers job to complement. Do brief explanation if necessary.2.
5、“Im conquering.” Its a game as w ell as a competition between boys and girls, which is intended to review some related vocabulary and help some students to enlarge their vocabulary. Rules are as the following: Students of either gender can take the initial to do the competition. For example, a girl
6、student stands up first, picks any prefix or suffix and then says one word containing that suffix or prefix. Then boy students cant not use that suffix or prefix any more because that field has been conquered. One student, one word a time. Boys and girls dont need to take turns. It all depends on ho
7、w fast their reaction is. But they have to make sure that following every suffix or prefix they have picked, there must be three different words. Then the side which conquers the largest field wins the competition.3. After the competition, teacher can add some words which appear on page 46 but are m
8、issed out in their answers such as illegal and disrespect.Tip: 1) Some words take a hyphen (-) when a prefix is added. 2) We sometimes need to change the ending of a word before we can add a suffix.Explanation本节所列的前后缀除了 pro-和 anti-之外，学生都很熟悉，让学生进行头脑风暴，在短时间内迅速反馈以往学过的前后缀，使学生产生一种成就感，对于新知识的接受从情感和速度上都有更好的
9、效果。对于学生没有想到的前后缀，就相当于是新的知识，要由老师进行补充，进行简单的解释即可。 “攻城略地”游戏改变了以往让学生写出同一个词缀尽量多的词汇这一模式，评判标准更科学，参与性更强，对学生的团体合作精神也是很好的培养和激发。并且让学生好像真的有在靠实力攻城略地的感觉，随着他们的“地盘”越来越大，竞争会更激烈，课堂气氛也更好。教师在最后补充一些词汇，效果也更佳。Step 3 Organs of the body (PPT11-17)1. Lead students to turn their focus to organs of the body by concluding: Differ
10、ent suffixes and prefixes have thei r specific meanings and you will find it easier to recognize those seemingly new words coated with prefixes and suffixes. If we call these suffixes and prefixes “ORGANs” of the vocabulary, then the “ORGANs” of our body are also playing different roles and having d
11、ifferent jobs to do. 2. Ask students to tell what human organs they have already been able to express in English. (Expected answers: liver, heart, etc.)3.

12、o th eir positions. And introduce relative English words. Ask students to explain their functions in English.4. Activity 1 Matching. Abstract five comparisons based on the passage on Page 47 and ask students to do matching and tell why. The reasons can be different from whatever presented in the pas

Ask students to read a short poem on organs and ask them to fill in the blanks according to different functions of the organs, which can also help students consolidate the vocabulary.6. Time permitting, students can do their own writing as well.Explanation本节出现的有关人体器官
14、的几个词汇都不难，没有必 要补充新的词汇。对 47页上的那篇短文进行了简化处理，提炼出 5 个比喻，让学生进行连线练习，为学生提供了想象和逻辑判断的空间。而后的另一个练习，让学生运用已知以及新学的词汇结合他们对于几个器官作用的理解进行诗歌的填空，同样是对学生能力的一个提升。课堂的气氛将在这时达到另一个小高潮。若时间允许，可以让学生进行简单的诗歌仿写，甚至只要仿写一句话即可，激发学生运用英语的兴趣。Step 4 Summary (PPT18)Ask students to briefly report what they have learned today.Explanation利用每节课的最
15、后 2 分钟进行简单的内容总结可以加深学生识记印象，也可以检测学生的掌握程度，同时也是教师自我检测的好时机，以便于在后面碰上同样的课型时可以进行有效的调整和改进。教后记：来源:学科网 ZXXK来源: 学科网 ZXXK高考链接拓展阅读Words：340 难度系数： 建议用时： 9 分钟Alices Adventures in Wonderland is one of the most loved childrens books of all time，and many adults enjoy it as well.It tells the story of a young girl named
