现在完成进行时表达的意义

（一）表示从过去某时开始一直持续到_______的动作，并且还将持续下去。

The Chinese have been making paper for two thousand years.

3. 注意事项

（1）

不能用现在进行时的动词，如be, have, like, love, know, see, hear等，也不能用现在完成进行时里，而应用现在完成时。例如：

The poor child has been ill for a long time. 译：______________________________ Have you seen her parents these days?

译：________________________________ （2）

现在完成进行时与现在进行时比较：

现在完成进行时强调某动作从过去一直延续到现在；而现在进行时只指目前正发生的动作。试比较：

Susan has been reading that storybook since last night. 译：_____________________ Susan is reading a storybook now. 译：____________________________________

（3）

现在完成进行时和现在完成时比较：

The teacher has been teaching at this school for ten years.

教学反思

本节课内容比较多，很多词汇、短语、语法需要记忆，但为了让学生不至于产生厌烦情绪，设置了多种形式学习，让学生在学习语言知识的同时，及时归纳词汇和语法的用法，掌握多种学习方法，这样就比生硬的说教效果要好。

同时为适应当前素质教育的深入推进的要求和出于对英语课堂教学和英语学***面积提升和促进的要求，为鼓励学生主动学习，积极学习，我们采取了课前课中课后的这样一种教学模式，课前自主探究，合作学习；课上交流展示、研讨提升；课后巩固提高、预习准备。我们希望通过老师所创设的这样一个教学流程，让学生通过自己的探索、研究，归纳、总结，解决问题、获取知识。从而真正达到学生自主学习、合作学习、探究学习、积极学习的目的。

总之，本节课的设计顺应全省规范办学行为、深化课程改革、推进素质教育的要求；更新教育教学观念，积极引导学生的课前自学，充分落实学生课堂的主体地位；积极引导学生学习方式的转变，倡导学生的主动学习、自主学习、合作学习和探究学习，是一节较高效的课。
