6、car is waiting for his daughter.(后置定语)坐在车里的男子正在等他的女儿。*The law being carried out is to ban drunken driving.(后置定语，强调正在被执行的法律)正在执行中的这则法律旨在禁止酒后驾驶。名师点拨(1)现在分词短语作定语时通常后置，而单个的分词作定语时可置于被修饰词的前面，也可置于被修饰词的后面。(2)现在分词的完成时的主动及被动形式均不作后置定语。2动词ing形式作状语。(1)作时间状语。*Working in the office,the clerk heard an explosion fro

7、m the street.在办公室工作时，这位职员听到街上发出了爆炸声。*Having finished her homework,the girl was busy with the thing she likes.完成了家庭作业，女孩就忙于做她喜欢做的事情。名师点拨动词ing形式一般式常表示该动作与句子谓语动作同时发生，而动词ing形式的完成式则表示该动作发生在谓语动作之前。(2)作原因状语。*Lacking enough money,they had to give up the plan.由于缺乏足够的资金，他们只好放弃了这项计划。(3)作条件状语。*Getting the chanc

10、he knew what to do next,he set out to do it at once.当明白下一步要做什么时，他立刻开始着手做起来。*The guide showed the visitors around the pictures explainingthe background of each picture.The guide showed the visitors around the pictures and explained the background of each picture.导游领着游客参观这些图画，并解说每一幅画的背景。二、难点突破1单个的动词in

11、g形式作定语置于被修饰词的前面时，注意下面的两种情况对比。*The old man needs a walking stick.The old man needs a stick used for walking.(表示用途)老人需要一把用于行走的手杖。*There are many people on the top of the mountain now who are enjoying the rising sun.There are many people on the top of the mountain now who are enjoying the sun which is

12、rising.(强调动作)现在山顶上有很多人在欣赏正在升起的太阳。2独立主格。现在分词作状语，有时它也可以有自己独立的逻辑主语，这种结构称为独立主格结构，通常用来表示伴随的动作或情况，也可以表示时间、原因或条件等。*Weather permitting,we will go out for an outing.如果天气允许，我们会出去远足。*The paper having been finished,the student handed it in.做完试卷之后，这位学生把它交了上去。3评论性状语。有些动词ing形式作状语，在句中没有逻辑上的主语而独立存在，用来修饰主句，表明说话者的态度、观

13、点等，被称为评论性状语或悬垂分词。常见的有generally/strictly/frankly speaking，judging from，considering，supposing，providing等。*Judging from what he has said，he is a doctor.根据他的话判断，他是位医生。*Considering that the old man is old,he needs looking after.考虑到老人老了，他需要被照顾。4动词ing形式作状语时，常将否定副词not置于分词前面。*Not having finished the work,the

14、y had to work extra hours.由于没有完成工作，他们只好加班。5状语从句转化为非谓语作状语时，若从句的主语与主句的主语一致，从句谓语含有be动词时，可保留从句的引导词。*When getting to the top of the mountain,they found the sun was rising.当他们到达山顶时，发现太阳正在升起。6动词ing形式与过去分词的区别(1)语态不同：v.ing形式表示主动概念，与相关的名词或代词之间构成一种“主谓关系”。而过去分词表示被动概念，与相关的名词或代词构成一种“动宾关系”。(2)时间不同：v.ing形式表示“正在进行的动

15、作”；过去分词表示“已完成的动作”。Seeing from the hill,you will see the beautiful city.在山上看，你会看到美丽的城市。Seen from the hill,the beautiful lake is like a big mirror.从山上看，那个美丽的湖就像一面大镜子。巧学助记分词短语记忆口诀分词作状语，主语是问题；逗号前后两动作，共用一主语；主语找出后，再来判关系；主动用ing，被动用ed；having done表先后，千万要牢记。课堂达标验收.句型转换(用非谓语动词结构变换句子)1The storm left and has cau
