高中英语必修4 Unit 3语法教案
Teaching aim: Grasp the usages of-ing form and use them freely 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 dancing girl(= a girl who is dancing)单个分词作定语,分词前置。We can see the rising sun.The sleeping boy is my son.分词短语作定语,分词后置;分词修饰不定代词something等要后置。The girl standing under the tree is my niece.There is nothing interesting.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。(1)Its full time job is laying eggs.他的专职工作是产卵。
(2)Our job is playing all kinds of music.我们的工作就是演奏各种音乐。(3)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。(4)The film is touching.(5)This girl is charming.(6)My job is interesting.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,listen to ,look at等。表示动作正在进行。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。She smelt something burning.⑵表示“指使”等意义的动词,如have, set, keep, get, catch, leave等.强调的持续性。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。The joke set them all laughing.The teacher often caught him sleeping in cla.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。
