Pahlsson and her husband searched the kitchen, checking every corner, but turned up nothing. 本句中,searched the kitchen, checking every corner, turned up不是三个并列谓语动词吗,为什么是checking(分词形式)?
My maternal grandmother, after having nine children who survived, one
who died in infancy, and many miscarriages, as soon as she became a widow
devoted herself to women's higher education.
请问这句话怎么分析,有谓语吗?
