环节说明：每节课复习上节课的词汇，短语，句型是非常有必要的。
学习一门新的语言记忆性的东西总是比较多，而人都是受遗忘曲线控制的，所以能够把一个东西记牢的方法就是反复重复，多记几次。
如果该节课的内容不是特别多，安排不是很紧凑的话，可以采取记单词比赛等小活动，带动课堂气氛。

【重点领悟】通过谈论薯条的发明，充分掌握被动语态的用法.
【探究提升】初中被动语态语法讲解
(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”等词用来表示被动，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，其形式与系动词be的变化形式完全一样。
一般现在时：am / is / are + done
一般过去时：was / were + done
一般将来时：shall / will + be done
一般过去将来时：should / would + be done
现在进行时：am / is / are + being + done
过去进行时：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 / would + have been + done
［注］被动语态没有将来进行时和过去将来进行时。
