21、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 didnt 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

22、。)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 couldnt understand it.正:He was told many times,but he still couldnt un

23、derstand it.或 Having been told many times,he still couldnt 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

24、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。,
