反义疑问句和主谓一致的问题
He must have read that short novel written by Mark Twain,____?(hasn't he)
She must have been out last night,________?(wasn't she)
有什么区别,都是have作陈述部分的,为什么后面不一样?
The poet and writer ________tomorrow moring.(is to be operated on)
If law and order _________preserved,neither the citizen or his property is safe.(is not)
这两句话求翻译,还想知道为什么A and B 谓语动词要用单数 Jane and Mary look alike.这句却用 复数谓语动词.
Fish and chips are getting very expensive.
Bread and butter is the everyday food in the west.这两句话我觉得也差不多 求解释

Answer 1

He must have read that short novel written by Mark Twain,____?(hasn't he)
She must have been out last night,________?(wasn't she)
如果在句中出现过去时间状语的话,如第二句last night,则用wasn't she.而第一句中没有出现具体的过去时间,所以用hasn't he.
The poet and writer ________tomorrow moring.(is to be operated on)
If law and order _________preserved,neither the citizen or his property is safe.(is not)
翻译：
这位诗人作者明天早上要做手术.
如果法律和秩序不能被保护,那么公民和他的财产也不会是安全的.
因为第一句话的主语是指同一个人,而第二句话中的主语是不可分割的,故动词用单三形式.
Fish and chips are getting very expensive.
鱼和炸土豆条将会变得很贵.主语是不同的事物,故动词用复数.
Bread and butter is the everyday food in the west.
这句话中的Bread and butter 是不可分割的整体,故谓语用单数.
不懂再问!
