______, both my father and mother died.
A．At the age of four
B．Being four years old

D．When I was four years old
参考答案
正确答案：D
解析：当介词短语作状语时，其逻辑主语应为句子的主语，否则该介词结构就成为悬垂结构，如：(×) Without a friend to counsel him，the temptation proved irresistible．(介词短语without a friend to counsel him与句子主语the temptation无逻辑关系，可将本句改为Because he hadn't a friend to counsel him，the temptation proved irresistible．
