幻灯片 11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。
----
幻灯片 12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。
----
幻灯片 13 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。
----
幻灯片 14(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）
----
幻灯片 15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。
----
幻灯片 16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.
----
幻灯片 17-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。
----
幻灯片 18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。
----
幻灯片 19Coming 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。
----
幻灯片 20 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 。)
----
幻灯片 21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。
----
幻灯片 22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,
