高中英语必修4 Unit 3语法教案 PeriodIV Grammer

Teaching aim: Grasp the usages of-ing form and use them freely I.Preparation for grammer before cla.STEP1.[自学探究]（SB P21 Discovering useful structures）

1.v.ing 做定语

▲动名词放在所修饰的名词前面作为定语，表示该名词的用途或有关的动作。walking stick 手杖

printing shop 印务馆

dining room饭厅

reading room 阅览室

swimming pool 游泳池

washing machine洗衣机 a waiting room(= a room for waiting)候车室 a walking stick(=a stick for walking)手杖

▲现在分词做定语，说明所修饰名词进行的动作。a waiting man(=a man who is waiting)正在等待的男人 a sleeping child(= a child who is sleeping)正在睡觉的孩子 2.v.ing 作表语

▲动名词做表语是对主语内容的解释，这时主语与表语位置可以互换。Its full time job is laying eggs.他的专职工作是产卵。

Our job is playing all kinds of music.我们的工作就是演奏各种音乐。Playing all kinds of music is our job.演奏各种音乐是我们的工作。

＊现在分词做表语，表明的是主语的性质与特征，主语与表语位置不可互换。The music they are playing sounds exciting.他们演奏的音乐是如此令人兴奋。The task of this cla is practising the idioms.这节课的任务是练习这些短语。Seeing is believing.眼见为实。

My work is looking after the children.我的工作是照看这些孩子。3.v.－ing作宾语补足语的用法

v.－ing 形式主要用于以下两类动词后构成宾语补助语。

⑴表示感觉和状态的动词，如see, hear, feel, smell, watch, find, notice等。例如: I heard Mr.Smith singing in the next door.我听到史密斯先生在隔壁唱歌。I felt someone patting on the shoulder.我感到有人拍了拍我的肩膀。

⑵表示“指使”等意义的动词，如have, set, keep, get, catch, leave等。例如: We won’t have you doing that.我们不允许你这么做。

I’m sorry to have kept you waiting long.对不起，让你久等了。II.Make a thorough inquiry during cla.Teacher and students work toghter.STEP2.精例点拨

1.The salesman scolded the girl caught _____ and let her off.A.to have stolen B.to be stealing C.to steal D.stealing [解析]本题考查动词非谓语形式在句中作宾补的用法。正确掌握并灵活运用非谓语形式是解此类题的关键，另外，解这一题目也要用还原法，即catch the girl stealing，若没有把catch the girl stealing 还原，也是很难找出本题的答案的，因此，解题时，不但要有扎实的基础知识，还要掌握解题技巧。本题旨在考查catch sb.doing sth.（发现某人做某事）这一短语，故先排除A、C两项，由于girl与catch之间是被动关系，因此需要用catch的过去分词形式作后置定语，stealing所作的只能是定语中的补足语，故本题最佳答案为D。

2.In the study, I found my son ______ at a desk, with his attention ______ on a book.A.sitting;fixing B.sit;fixed C.sitting;to be fixed D.seated;fixed [解析]此题考查不定式与分词作宾补的区别以及短语fix one’s attention的用法。解答此题时，应特别留意不定式与分词作宾补的区别；第二应注意倘若逻辑宾语提前，则with+复合宾语中宾补应用过去分词表示被动。因为强调found的动作与sit同时进行，而省去to的不定式sit作宾补表示动作的完成，但sitting和seated皆可。第二空中，attention原为fix的逻辑宾语，所以应选fixed作宾语补足语。故此题正确答案为：D。III.当堂达标
