英语基础问题——————被动态2---今日内选择最佳答案
1.the wailman sometimes pushes letters through an opening in the door
被动态：the door is sometimes pushes letters through an opening by the mailman
是pushes 变成 pushed 还是应该 opening 变成 opened
上面的对吗?有什么错误,我应该怎么弥补?还有其它问题

Answer 1

句意：
有时邮递员把信件从门缝里（开着的门里）推进去.
被动语态应该是：
The letters are sometimes pushed through an opening in the door by the mailman.
记住,被动语态只要改谓语动词,上面的opening不是谓语,所以不用改.
