1、现在分词的完成时、被动式和完成被动时,By 覃成海,现在分词的黄金法则:现在分词的逻辑主语是句子的主语,分词作定语时的逻辑主语,分词作定语时的逻辑主语就是它所修饰的词An interesting bookA rolling stone,黄金法则:一般情况下,作状语的分词的逻辑主语就是句子的主语,用以上原则判断下面的句子哪几句是正确的 Turning around,an old woman was seen walking towards the riverTurning around,we saw an old woman walking towards the riverSeen from
2、the hilltop,he was delighted to see a wonderland of a valleySeen from the hilltop,the valley looked like a wonderland When using this machine,you must read the instructions first.When using this machine,the instructions must be read first,如果现在分词的逻辑主语不是句子主语?,会出现三种情况,部分分词已经演变成固定搭配,变成分词的独立结构,悬垂结构,变成固定搭
3、配,分词作状语时,在少数情况下,其逻辑主语与句子的主语不一致,分词用来修饰全句Judging from appearance,he seems to be a strong manGenerally speaking,this novel is not very inspiring这种情况只限于少数几个动词例如:broadly speaking,considering,Talking of,regarding the plan,等,变成分词的独立结构,分词作状语时,其逻辑主语与句子的主语应该一致,否则,分词应有自己的逻辑主语,构成分词的独立结构。,悬垂结构,分词短语相当于状语从句,其逻辑主语通
4、常就是主句主语,例如:Looking up at the sky,she saw the moon shining bright and clear.上立中句子的主语是she,因此,looking up at the sky=as she looked up at the sky;可见,这个分词短语的逻辑主语是句子的主语she。如果分词短语的逻辑主语不是句子的主语,这样的分词短语就是悬垂结构,例如:Looking up at the sky,the moon shone bright and clear。悬垂结构是该避免的病句,归纳起来有以下几类:,1.悬垂致病的分词结构,Walking al

7、ied out from the mountains.From attending the class,the principles of physics were made clear主语coal不可能建造铁路,故不能充当build的主语;the principles of physics不能充当attending的主语。改正悬垂结构有两个方法:一是改变句子结构,使句子主语能成为动名词的逻辑主语,二是在动名词前加上代词或名词的属格,使动名词有自己的逻辑主语。By building a railway there,people can carry coal out from the mount
8、ains.By our building a railway there,people can carry coal from the mountains.From attending the class,we made clear the principles of physics From our attending the class,the principles of physics were made clear,3.悬垂致病的不定式结构,不定式短语常放在句首,作目的状语,其逻辑主语必须是主句的主语,否则就为病句To speak English well,a lot of pract
