关于A 选项的doing结构,doing除了修饰前面一整句话表示结果,不是还可以由句子主语发出这个动作么,在这里:
Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.表示信件发出的Outnumbering这个动作不可以么?
