after后面直接加动词,就是介词.那用 after doingafter后面有人称,还有动词,那是连词,连接句子.After finishing homework, he went to bed after介词After he finished hishomework, he went to bed. After...有after ed的说法么？介词+名词/ 动名词连词+句子所以 after后面直接加动词，就是介词。 after doing （介词短语做状语） after后面有人称，还有动词，那是连词，连接句子。 After+主语+谓语（时间状语从句）有当介词使直接加动词被动ED的么没有直接加ed的，但是有被动 After being -ed
