Walking slowly down the road, he saw a woman accompanied by two children.
沿路漫步时,他看到了一个带着两个孩子的女人。
walking 修饰的是句子的主语 he ,而不是 a woman 。如果需要修饰那个女人,必须重新组织句子:
He saw a woman, accompanied by two children, walking slowly down the road.
他看见一个带着两个孩子的女人正沿路漫步。
当连词后的分词短语,介词后的动名词短语,做同位语的名词短语或形容词短语位于句首时,也需遵守上述规则。例如:
违反规则11的句子往往滑稽可笑:
Being in a dilapidated condition, I was able to buy the house very cheap.
我残破不堪,所以能以很便宜的价格买下那栋房子。
Wondering irresolutely what to do next, the clock struck twelve.
时钟犹豫不决地四处乱逛,于是敲响了12点。
