课件35张PPT。When was it invented?Unit 6第三课时：Section A (Grammar Focus-4c) 同学们，上一课学习的单词你们都掌握了吗？现在大家来检验一下，点击下面的音频开始听写吧！ Unit5已经学习了一般现在时的被动语态，这节课我们一起来学习一下一般过去时的被动语态。 Grammar Focus一般过去时的被动语态一般过去时的被动语态的构成：was/were＋及物动词的过去分词。魔法 记忆被动语态用法顺口溜： 一般过去时，被动用be＋done； be形式有两种，主单was主复were； 疑问提前be，否定be后not挤。语法讲解判断时态是一般现在时还是一般过去时。考点 1考向判断是一般现在时的被动语态还是一般过去时的被动语态。典例—Why didn’t you go to the New Year’s party last Friday? —Because I _____. (遂宁) A．was invited B．wasn’t invited C．didn’t inviteB【点拨】句意：———上周五你为什么没有参加新年晚会？———因为我没有被邀请。上句提到了last Friday，所以应用一般过去时的被动语态。wasn’t invited一般过去时的被动语态的否定形式。 被动语态结构中的be用was还是用were。 考点 2考向主语的单复数决定be用was还是用were。 典例So many trees and beautiful flowers _____ in this area in 2014. (恩施) A．were planted B．was planted C．are plantedA【点拨】本题用主谓一致法解题。根据句子的时间状语in 2014可知本句应用一般过去时，主语trees and flowers是复 数，be应用were。 在主动语态中make，see等动词后接省略to的不定式作宾语补足语，变成被动语态时，不定式符号to要还原。考点 3典例Though he often made his little sister _____， today he was made _____by his little sister. (汕尾) A．cry；to cry B．crying；crying C．cry；cry D．to cry；cry 【点拨】本题用语法判定法解题。make 用作及物动词，意为“使，让”，在主动语态中其后要跟省略to的不定式作宾语补足语，而在被动语态中，to不能省去。 A 典例Old people weren’t _____ good _____ in the past. A．take；care of B．taken；care C．took；care D．taken；care of 【点拨】考查固定短语。take care of照顾，照料，在被动 语态中不能漏掉介词。D在主动语态中，动词短语中的介词在变为被动语态时，仍要跟在原动词之后。 考点 4主动语态若有双宾语，变为被动语态时，间接宾语(人)和直接宾语(物)都可变为主语，动词后一般要用相应的介词与其搭配。 eg：He gave me a book. (改为被动语态) A book was given to me by him. I was given a book by him.考点 5魔法记忆变被动语态的口诀：宾提前变主，主变介by宾；谓语be 加done，时态看主动。如遇双宾语，最好变间宾；若要变直宾，间宾前加to/for。主动中省to的不定式，被动中to加上。 魔法 记忆Rewrite the sentences using the passive voice. 4a1．They sold the fridge at a low price ?.
