When he came back home from his night shift, Jason tried to avoid wakening his family.After hearing the funny story, all of us couldnt help laughing ear to ear. Thank you for offering me so much help.The children are busy doing their homework.developing countries 定语 working people 定语StepIII师导生学，互动探究（师生互动）一、V-ing被动形式的构成（group work 师导生学 合作探究）【观察探究】V-ing 一般时和一般时的被动形式;1） He hurried home , looking behind from time to time .2) The building being repaired is our dormitory .V-ing 的完成时和完成时的被动形式1) Having lit a candle , she went out.2) Having been asked to stay , I couldnt leave .3) Having heard this , our teacher expressed her satisfaction .【归纳总结】如果v-ing与句中的逻辑主语构成被动关系，即当动词-ing 形式的逻辑主语是动作的承受者时，需用其被动形式（being done，having been done）。其否定形式是：not being done, not having been doneV-ing 形式表示的动作与主句谓语动词同时发生，用其一般式; V-ing 形式表示的动作在主句谓语动词之前发生，用其完成时。【即学即练】人们不喜欢无缘无故的赞扬。People hate being praised for nothing . 这问题远没得到解决。The problem is far from being solved . 她不介意被一人留在家里。She didnt mind being left alone at home .没有被邀请参加聚会，他感到很不高兴。He was unhappy for not having been invited to the party.尽管被告诉好多次了，但他仍然犯同样的错误。Having been told many times, he still made the same mistakes.二、v-ing被动形式的语法功能（互动交流，突破疑难）1.作主语Swimming is good for health._ (raise) your hat to a a lady is good manners . 对一位女士脱帽致敬是礼貌的。 _ (kill) by sharks in the sea is a common thing .2. 作表语(往往表示一种概念，习惯或经验，或说明主语的内容.)Teaching is learning 教学相长My hobby is _ (make) model planes. Her regret is_ (abandon) by him.注意1). V-ing形式和不定式都要有对称性 To see is to believe.= Seeing is believing.2).动名词和不定式都可以作主语，动名词作主语表示一般或抽象的多次性行为，不定式作主语往往表示具体的或一次性的动作。如：Playing with fire is dangerous. （泛指玩火）To play with fire will be dangerous.（指一具体动作）3.作宾语We would appreciate hearing from you我们会珍惜你的来信。 The bird escaped _ (catch) . He was afraid of _ (abandon) by us.V-ing 形式既可作动词的宾语, 也可作介词的宾语。注意： 在 avoid, admit, appreciate, consider, delay, enjoy, escape, excuse, finish, forgive, imagine, mind, miss, practise, risk, suggest, give up, put off, feel like, insist on , instead of, look forward to, object to, keep on等后只接V-ing形式作宾语。4.作宾补I heard her _ (sing) a song in her room.I heard the song ( sing ) in English. Youll find the topic _ (discuss) everywhere now. 5. 作定语The girl standing there is my sister .This is a piece of _ (surprise) news .The problem_ (discuss) now is very important. 对比填空a meeting (hold) now / a meeting (hold) yesterdaya meeting (hold) tomorrow6. 作状语Hearing the good news , he jumped with joy .He sat at the table , _ ( read ) China Daily ._ (ask) to answer the question, she couldnt refuse. ( tell) many times, he still made the same mistakes.三v-ing几个重要用法在want，need，require，deserve等动词之后作宾语时，常用v-ing的主动式表示被动意义。Your car needs filling. 你这车要充气了。This city deserves visiting. 这座城市值得光顾一下。The problem requires studying carefully .这个问题需要认真研究。The trees want watering .这些树需要浇水了。在（be）worth后面只能用动名词的主动态来表示被动意义。His suggestion is worth considering. The book is worth reading.在allow，advise，forbid，permit等动词后直接跟动名词形式作宾语，如果后面有名词或代词作宾语，其后用动词不定式作宾语补足语。如：We dont allow smoking here. We dont allow students to smoke.
