printing shop 印务馆
dining room饭厅
reading room 阅览室

▲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
