below. Examine the sentences and discuss in what way the structures similar to each other and in what
way they are different.Looking carefully at the ground, I made
my way to the edge of the crater.Having experienced quite a few earthquakes
in Hawaii already, I didn’t take much notice.The –ing form used as an adverbial.Having + past participle (the perfect -ing
form) to refer to an action that took place before the time expressed by main verb.小结-ing 形式的用法
1. –ing 形式作状语2. –ing形式的完成式例句：
(Having been) written in haste, the book has some faults. 这本书因仓促写成，所以有些缺憾。分词 (短语) 作状语时, 其逻辑主语必须与句子的主语一致。如果不一致，必须用独立主格结构来表示，也就是在分词前面加上它的逻辑主语。 3. 使用- ing形式需注意的几个问题。 My wife had a long talk with Sally,
explaining why she didn’t want the
children to play together.
我妻子与莎莉谈了很长时间, 解释她为什么不想让孩子们在一起玩。(现在分词explaining是句子主语my wife做的动作,它们之间是主动关系, 即explaining的逻辑主语，就是句子的主语my wife 。) The train having gone, we had to wait another day.（the train逻辑主语 + having gone 即为独立主格结构）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)，因为并列连词接的是两个并列成分，而分词短语只是全句的一个状语部分，分词和主句之间可用逗号。例如: 误: Having been told many times, but he
still couldn’t understand it. 正: He was told many times, but he still
couldn’t understand it. 或
Having been told many times, he still
couldn’t understand it.-ing的一般式和完成式现在分词都可以表示先后接连发生的动作。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。例如:
Opening the drawer，he took out his
wallet. (=He opened the drawer and took out his wallet.)
他打开抽屉，拿出钱包。Coming into the room, he put down his bag. (=He came into the room and put down his bag.)
他走进房间，放下提包。 Having brushed his teeth, Mr. Brown
came downstairs for breakfast.
布朗先生刷过牙, 就下楼来吃早饭。 (此句如写成: Brushing his teeth,
Mr. Brown came downstairs for
breakfast. 可能指 “边刷牙, 边下楼 。)
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。例如: Not fearing the fire, the child touched
and got a finger burnt. 小孩儿不知道 怕火，用手去摸，把手指烫了。 Not knowing how to find the subway,
I asked a policeman for help. 我不知怎样找到地铁，就去找警察帮忙。 I. 每空填一词，使该句与所给句子的意思相同。
