语法:
(一)语态分类
英语动词有两种语态.,主动语态和被动语态。

主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。

如:
They will build a new bridge over the river.(主动)
A new bridge will be built over the river.(被动)
汉语中常用“被”、“给”、“由”、“受”等词用來表示被动,而英语用:
助动词be +及物动词的过去分词构成。

(二)被动语态的时态、人称和数的变化主要体现在be的变化上,英形式与系动词be的变化形式完全一样。

—•般现在时:am / is / are + done
—•般过去时:was / were + done
—般将来时:shall / will + be done
—般过去将来时:should / wou 1 d + be done
现在进行时:am / is / are + being + done
过去进彳亍时:was / were + being + done
现在完成时:have / has + been + done
过去完成时:had + been + done
将来完成时:shall / will + have been + done
过去将来完成时:should / wou 1 d + have been + done
[注]被动语态没冇将來进行时和过去将來进行时。

八、板书设计:
Unit 6 When was it invented?
1.When was it invented ?
Who was it invented by ?
What? s it used for ?
2.The Passive Voice:
Be +动词的过去分词形式
3.be used for doing sth
九、教学反思: 本课主要话题是谈论重耍发明的发明时间、发明者及川途。

主要练习被动语态的句式丿IJ法。

难度较大,但是学生们对发明话题很感兴趣,所以学习积极性很高。

反思这堂课的教学,我认为优点冇以下儿点:
1、从学生熟悉的话题入手,引导学生理解课文;
木节课教师从学生熟悉的发明话题入手与学生进行讨论,学生接受,全员参与,很好的调动了学生的学习热情,为整节课做好了铺垫。

通过第一遍听录音回答简单问题,到第二遍听进一步M答问题,再到最后听并跟读,教学设计有层次性,由简到难,由浅到深,弓I导学生一步步进行学习。

2、利用点读笔做听读训练,方便高效,学生喜欢;
在学习单词和课文的环节,我利用点读笔的功能让学生听录音进行学习,山于点读笔发咅清晰纯正,因此听得清,模仿得也好。

学生最后朗读的时候不仅冇声冇色,表情也自然而然带了出来。

由于模仿效果好,学生有了自信,特别是我利用点读笔下去到学生屮间点读的时候,很多学生非常兴奋,声音洪亮整齐地到读课文。

课堂气氛非常热烈。

合理利用点读笔的功能,可以有效提高学生的学习效率,学习效果和学习热情。

小学生处于学习英语的初级阶段,对正确的语音语调和语流中肌型发音特征规律的了解和掌握学习对其以后的听说学习影响非常大。

教师应注意在这些发音方面做处理。

帮助学牛掌握这些发音规律。

3、与学生积极进行了交流。

尤其是小组学习过程和展示过程屮,教师做到了很好的指导和楮讲点拨,做到了三讲三不讲。

教师的评价及时到位,评价语比较丰富。

时间把握比较紧凑,均衡分配了单词和课文的学习时间和教学内容。
