现在分词作状语课件

1、Part Grammar现在分词作状语思维导图 一、现在分词作状语的用法 现在分词(短语)在句中作状语用来修饰谓语动词或整个句子，表示动作发生的时间、原因、条件、结果、方式、让步或伴随状况。1作时间状语现在分词作时间状语时，常放在句首，相当于一个时间状语从句。Hearing the noise，I turned round.When I heard the noise，I turned round.听到响声我转过身去。2作原因状语现在分词作原因状语时，相当于一个原因状语从句，也可以放在句首。Being poor，he couldnt afford a TV set.Because he was

2、 poor，he couldnt afford a TV set.由于贫穷，他买不起一台电视机。3作条件状语现在分词作条件状语时，相当于一个if引导的条件状语从句。Working hard，youll certainly succeed. If you work hard，youll certainly succeed.只要努力学习，你肯定会成功的。4作结果状语现在分词作结果状语时，通常放在句末，中间用逗号隔开，表示一种顺其自然、意料之中的结果。The fire lasted a whole night，causing great damage.大火持续了一整夜，造成了巨大损失。名师点津现在分

3、词作结果状语，是随着谓语动词的发生而产生的自然结果，其逻辑主语往往是前面整个句子所描述的情况，前面有时候可以加thus。而不定式作结果状语时常表示出乎意料的结果，常用only to do结构其被动形式为only to be done。He was caught in the rain，thus making himself catch cold.被雨淋后他感冒了。I hurried to school，only to find it was Sunday.我匆忙赶到学校，结果发现是星期天。5作让步、方式和伴随状语现在分词作让步、方式和伴随状语时，说明动作发生的背景和情况。作伴随状语时，表示分词

4、的动作和主句的动作同时发生，此时它可转换成并列句。Mary sat by the window of the classroom，reading a book.Mary sat by the window of the classroom and was reading a book.玛丽坐在教室的窗边读书。二、现在分词作状语注意事项1现在分词的时态现在分词作状语时，要注意分词的时间性，是用现在分词的一般式(doing)，还是用完成式(having done)。(1)当现在分词的动作与谓语动词的动作同时发生时，用分词的一般式。Walking in the street，I met an old

5、 friend of mine.我正在大街上行走时，遇到了一位老朋友。(walking和谓语动词met同时发生)(2)当现在分词的动作先发生，而谓语动词的动作后发生时，用分词的完成式。Having finished the letter，he went to post it.他写完信后就把它寄了出去。(having finished是先发生的，went是后发生的)2现在分词的语态使用现在分词的主动式还是被动式，这主要取决于现在分词和句子主语之间的关系。句子的主语就是分词的逻辑主语。Having been shown around the factory，they were very happy

6、.(现在分词的被动式)被领着参观了工厂后，他们很高兴。Having finished his homework，he went to bed.(现在分词的主动式)完成了作业后，他上床睡觉。3动词ing形式的否定式：notv.ing；not havingv.edNot knowing this，he didnt come.他不知道这件事，所以没来。Not having made full preparations，we put off the sports meeting.因为没有做好充分的准备，我们把运动会延期了。4独立主格动词ing形式作状语，有时它也可以有自己独立的主语，这种结构称为独立主

7、格结构，通常用来表示伴随的动作或情况，也可以表示时间、原因或条件。The trees are extremely tall，some measuring over 90 metres.那些树非常高，其中一些高达90多米。The weather being fine，we went out for a walk.由于天气好，我们去散步了。5现在分词作评注性状语有些现在分词在句中没有逻辑主语，它们往往作为句子的评注性状语来修饰整个句子，表明说话者的态度、观点等。例如：generally speaking “一般来说”，judging by/from.“从判断”，taking everything
