“状语从句的省略”的两大原则中,是不是只有“主从主语一致”是必要的,“从句包含be动词”不满足也可以?
“状语从句的省略”的两大原则:
①主句和从句的主语一致,或从句主语为it;
②从句主要动词是be的某种形式。
在此种情况下可以省去从句的主语和be动词.保留be之后的部分,被保留部分常为现在分词、过去分词、不定式、形容词等。
但下面这句话的省略就明显不满足第二点啊,为什么会出现这种现象呢?
After she finished the housework,Polly had a walk with me.
省略后:After finishing the housework,Polly had a walk with me .
至于比较状语从句的省略就更加不需要满足上面那两大原则了,为什么?
如:He is a head taller than I(am tall).
辛苦老师解答一下!!
1. After she finished the housework,Polly had a walk with me.
◆after 是连词。
2. After finishing the housework,Polly had a walk with me .
◆after 是介词,finishing 是动名词。这不是、也不符合从句省略主语和 be 动词的规则,因为上句不是 after she was finishing...,故不是上句的省略。这种从句省略的结果是:原来的连词仍然是连词,finishing 是现在分词。例如:When I was walking on the street, I found a wallet. = When walking on the street, I found a wallet.
3. He is a head taller than I am tall.(误)
◆比较项形容词决不能在从句中出现。改为:
He is a head taller than I.
He is a head taller than I am.
He is a head taller than me. (非正式英语,than 作介词)

但下面这句话的省略就明显不满足第二点啊,为什么会出现这种现象呢?
After (连词)she finished the housework,Polly had a walk with me.
省略后:After finishing the housework,Polly had a walk with me .
【答】因为从句主要动词不是be的某种形式,而是实义动词 finished ,所以不能说:After finished the housework,Polly had a walk with me.
但是,可以说:After(介词) finishing the housework,Polly had a walk with me .
至于比较状语从句的省略就更加不需要满足上面那两大原则了,为什么?如:He is a head taller than I(am tall).
【答】 than I(am tall)是比较状语从句,可以省略与主句相同的结构(不是“省略主语和be动词”)。
