《动词ING做状语》PPT课件.ppt

1,非谓语动词 V-ing 形式做状语,2,动词-ing形式作状语,动词-ing形式可以作状语，在句中表示时间、原因、结果、条件、让步、行为方式或伴随情况等,相当于一个状语从句。动词-ing形式作时间、原因、条件、让步状语时多位于句首；作结果、伴随情况状语时常位于句末。,【教法探析】,3,E.g.: 1.walking along the street, I met Mary =while I was walking along the street, I met Mary 2.Having got home, I found my book missing =After I got home, I found my book missing,动词-ing形式可以作状语表时间，相当于一个时间状语从句，表与主句的谓语动作同时发生，如果从句的谓语动作发生在主句的动作之前，用动词-ing的完成时态即having +P.P,4,4.Turning to the left, you will find the school = If you turn to the left, you will find the school 表条件，相当于一个条件状语从句,5.Knowing where I live, he never come to see me. =Though he knows where I live, he never come to see me 表让步，相当于一个让步状语从句,3.Being tired, I stopped to take a rest =Because I was tired, I stopped to take a rest 表原因，相当于一个原因状语从句,5,6. I stood there, waiting for her =I stood there and waited for her 表示行为方式、伴随情况或补充说明，相当于一个并列结构,7.it rains heavily, causing severe flooding in the area =It rained heavily so that it caused severe flooding in the area 表结果，相当于一个结果状语从句,6,分词作状语，其逻辑主语是句子的主语，若分词的逻辑主语不是句子的主语，分词需要带有自己的主语，从而构成独立主格结构,E.g. :1.My wife had a long talk with Sally, explaining why she didnt want the children to play together (析：现在分词explain是句子主语my wife做的动作，它们之间是主动关系，即explain的逻辑主语就是句子的主语my wife). 2.The train having gone, we had to wait another day 。(析：因为的go动作不是句子的主格发出的，所以必须加上自己的动作发出者the train 逻辑主语+having done即为独立主格结构),7,独立结构v-ing的用法,8,1. 英语中一些固定表示独立主格结构的v-ing有： Generally speaking 一般说来/坦白地说 Judging from 根据 判断 Supposing/ soppose+从句 假使 Providing/provided +从句 假使 Granting/granted +从句 即使 Considering Seeing that 鉴于 ，考虑到 Given that Talking of 谈到 ,E.g. : Generally speaking, I forgot to tell her this matter.,9,2with + 复合宾语结构,这种结构也可以看成是一种独立主格结构。这种结构有较鲜明的特色。在这种结构中，with后的宾语相当于该结构中的逻辑主语，其后面的词相当于这个结构中的逻辑谓语。这个结构很像一个用来说明附带情况或细节的，可以起状语作用的句子。翻译时，with原有的含意往往不翻译出来。,10,with + 名词 / 代词 + -ing分词 With the old man leading, the two started toward the mountains.

A. realizing B. realized C. to realize D. being realized 【答案】A 【解析】首先要弄清楚本句中的and连接的成分是非谓语动词做状语，主语与press是被动关系，但是与realize是主动，“被父母迫使同时自己也意识到他已经浪费了太多时间，这个男孩决定停止玩电脑游戏。本题考查非谓语动词的难度挺大，主要是很多学生看到pressed后就不知道realize在句中做什么成分，所以本题关键有两个，一个是and并列的成分是什么，然后就是realize与主语the boy的关系。,28,(2012 湖南卷） The lecture, _at 7:00 pm laze night, was followed by an observation of the moon with telescopes.
