文中一句话：She's next door,请问door前面不需要加the吗? 请问为什么she's next door没有加介词in呢 She's next door 这里的she's 是不是she is?She is next door? she is next door. she lives next door. 请问there's a bar next door to the station.的语法?next door to 是介 she's next door 中next door 做什么成分 是什么词性 she‘s the girl next door,Nice,but not in a heart that’s pure she is next door 为什么不加in she's next door的表语是什么性质 she is next door.此处next door from door to door怎样加s
