吉林省长春市实验中学高中英语《Unit 3 Period 5》导学案 新人教版选修 7【学习目标】学习、掌握 doing 的被动形式 being done 的用法。【自主学习】1.思考，回忆关于动词的 ing 形式(doing)即动名词, 现在分词的被动形式(being done)的知识。2.重读课文，在课文中找出含有 doing 的被动形式即 being done 的句子, 感知他们的用法。【问题探究】 注意 being done 的特点，功能及用法。 动名词的被动形式【基础过关】1）当一个动名词逻辑上的主语所表示的是这个动作的对象时，这个动名词一般要用被动形式So being killed by sharks was a common occurrence. He could not bear being made fun of like that. 2）在 want, need, deserve, require 等动词后，尽管表示的是被动的意思，我们却用动名词的主动形式。My pen needs filling. The point deserves mentioning.【拓展延伸】 现在分词的被动形式在表示一个被动动作时，如果这个动作是现在正在 进行的，或是与谓语表示的动作同时发生的，我们可以用现在分词的被动。这种形式可以用来：(1) 作定语That building being repaired is our library. He asked who was the man being operated on.构成复合结构You’ll find the topic being discussed everywhere. He often watched the boated being unloaded.（2）作状语Being asked to give a performance, she couldn’t very well refuse.Being protected by a thick wall, they felt they were quite safe.有时还有完成被动形式：Having been given such a good chance, how could she let it slip away?The decision having been made, the next problem was how to make a good plan.【课堂练习】1.--- What made Bill so angry? --- ______.
