英语单选求解 27. (2012山东,35)After completing and singing it, please return the form to us in the envelope ______. A.providing B.provided C.having provided D.provide
After completing and signing it,please return the form to us in the envelope________. 答案:B 解析:考察非谓语动词做定语.动词provide与其逻辑主语envelop是被动关系,在句中作定语,相当于which is provided. 题意为:“表格填完之后,请将其放入为您提供的信封中,返还给我们”.这里的信封是被提供的,因此是被动关系.
