“双减”政策性下英语学习的“举一反三”与“举五归一”

最近读到了下面一段话,结合现在的“双减”背景,让我对教学中的如何切实减轻学生负担,提高学习效率有了更深的思考。原文如下:
 
教师对教学活动的作用主要在组织、引导和转化方面。比如,教师执教“液体的热胀冷缩”时——教师拿着一瓶橘子水走进教室,想办法把学生的注意力引到教学活动中,这就是“组织”;教师用手指比画瓶子上方的空余之处,让学生发现这瓶橘子水为什么没装满,这就是“引导”。这两点很容易做到,但许多教师往往忽视“转化”这一过程。
教师让学生做了一道题、两道题、三道题……是否教出了共通性、可迁移的知识?如果没有,学生即使再做10道题,只要题目略有不同,依然无从下手。优秀的教师能够让学生举一反三,而水平低的教师可能举十都不能归一,反而不得不布置更多习题,这也是学生学业负担重的原因之一。(--陈大伟,成都大学师范学院
那么,教学中我们如何才能成为高手教师,让学生达到“举一反三”,或者退一步讲,让学生达到“举五归一”,生成“有效课堂”,或者达成“有效训练”呢?下面以devote为例简单说一下自己的做法。
 
【观察与分析】
1. Jane devotes herself to teaching the deaf children and she has little time to care for her own daughter.
2. Devoting herself to teaching the deaf children ,Jane has little time to care for her own daughter.
3. Devoted to teaching the deaf children,Jane has little time to care for her own daughter.
思考:
  1. 以上三句话含义是什么?
  2. 句子结构怎么分析?
  3. 句中devote在句中作什么成分?是如何使用的?
  4. 句中现在分词和过去分词的使用规则是什么?
【比较与判断】
1. I still remember what you have devoted to ___________(improve) my oral English and English writing.
2. He is a __________(devote) father because he was strict with his daughter and encouraged her when she was in trouble.
3. Martin Luther King was respected for his ___________(devote) to the cause of the world peace.
4. Thinking of what you have devoted so much energy to ___________(encourage) me a lot to improve my oral English and English writing.
问题:
  1. 以上四句话的含义是什么?
  2. 以上四空你是如何填写的?都对了吗?
  3. 哪些地方出错了?出错的原因找到了吗?
  4. 第1题和第4题有哪些不同?你是如何判断的?
【概括与归纳】
(1)devote...to (doing) sth. 
把……献给;把……致力于
devote oneself to  致力于;献身于;专心于
(2)devoted adj.  挚爱的;忠实的
be devoted to (doing) sth.  
献身于(做)某事;专心致志于(做)某事
(3)devotion n.  深爱;奉献

【实践与应用】

  5. She devoted herself to tennis in her teens.她在少女时代热衷网球。
  6. The students are devoted to their studies.学生们专心于学习。
【迁移与创新】
思考:
  1.  occupy的用法与devote的用法有相似之处吗?
  2. 你可以总结一下occupy的用法吗?
  3. 请借助词典查阅expose, absorb, bury 的用法并思考与上述devote,occupy两个词有哪些相似之处?
    请完成下列练习:
    expose
  4. 普通表达)If you ___________________(把自己暴露在) the sunlight for too long, you will get your skin harmed.
  5. (高级达)__________________________________ ________will be harmful to your skin.(动名词短语作主语)
  6. (高级表达) _______________________________,you will get your skin harmed.(过去分词短语作状语)
    absorb
  7. (普通表达)Tom _____________________________ (工作很投入),so he forgot to inform me of the time of the meeting.
  8. (高级表达) _______________________________,Tom forgot to inform me of the time of the meeting.(现在分词作状语)
  9. (高级表达) ______________________,Tom forgot to inform me of the time of the meeting.(过去分词作状语)
    bury
  10. Because he _______________________ __________(埋头于) his book,he didn’t notice that all the others had left.
  11. (高级表达) ______________________________,he didn’t notice that all the others had left.(现在分词作状语)
  12. (高级表达) _____________________,he didn’t notice that all the others had left.(过去分词作状语)
【我的总结】
结合五个词的重点讲解和训练,学生们就会对同类词性的相似用法有了更为深刻、全面的认识和了解,对于核心概念和用法的提取也会有新的感悟和突破。这时,再进行纵横向的深入和拓展,就可以实现“举一反三”、“举五归一”、“举三返一”。
be absorbed in (doing) sth.结构在句中作状语、定语时,常用其过去分词形式absorbed in...。类似的结构还有:be lost in...陷入……,专心致志于……;be caught in...被困在……;be buried in...埋头于……;be devoted to...致力于……,专心于……;be occupied in/with...忙于……;be involved in...专注于……
