首先，用讲授法系统的讲述doing和having done 以及其被动语态，然后，讲述ing形式做状语的几种情况，时间状语，原因状语，条件状语，伴随状语和结果状语等栏目下，都给出了中英例句，帮学生理解。最后比较了不定式，过去分词和v-ing形式的用法，并且及时巩固，能够消除学生对这一知识点的误区.本课件中的练习以改错为主，这也是出于和全国高考卷中改错题型保持一致的目的。-ing分词的构成 ??? -ing分词是由动词原形加词尾-ing构成，表示与主语主动关系。-ing分词同样有时态和语态的变化，通常有下表几种形式（以do为例）2. –ing形式的完成式-ing分词的否定形式是由not /never
加-ing分词构成。如：
Not knowing his address, I could do nothing but stay at home and wait.
不知道他的地址，我只好在家里等着。 -ing分词的被动式-ing分词的被动式表示与后面句子的主语是被动关系。根据-ing分词动作发生的时间，被动式有一般被动式(being done)和完成被动式(having been done)。如： （Having been criticized） by the teacher, he gave up smoking. ?????? 被老师批评以后，他把烟戒了。___________ 主动，进行
_______ 被动, 完成
_____________ 将来；目的
_______________强调动作先发生 being done
to be done

All the tickets having been sold out, they went away disappointedly.
所有的票已经卖光了，他们失望地离开了。
Time permitting, we'll do another two exercises.
如果时间允许，我们将做另两个练习。
有时也可用with (without) +名词（代词宾格）+分词形式
With the lights burning, he fell asleep. 他点着灯睡着了。独立成分：
有些分词短语可以做独立成分，用来解释整个句子，不受句子主语的限制。常见的分词短语有：generally(frankly,honestly…) speaking, supposing (假设), judging from(从…判断), talking of（谈到), speaking of（谈到）等。
Generally speaking, girls are more careful than boys.
Supposing you lose, what will you do?
Judging from his accent, he must be from the north.
Talking of travel, have you ever been to Beijing? 使用- ing形式需注意的4个问题.1、分词 (短语) 作状语时, 前后两个动作的主语是同一个人。
2 、分词短语做状语时，前面可以加上连词或介词，但是分词短语和句子之间不能用并列连词(如but，and)，分词和主句之间可用逗号。3、用V+ing一般式 还是Having+done完成式，要看前后两个动作有没明显的先后顺序，在可能引起误解的场合应该用完成式现在分词表示先发生的动作。
4、分词的否定形式是在分词短语前面加上 not, never等否定词构成。
