A AnD B is/ArE

A and B are A and B 表示复数,用are

一、A and B is 还是are的具体分析:(参考精品学习网,新东方网) 1.如果and连接的是两个单数可数名词并且两个名词前均有冠词,就意味着这是两个人或物,谓语动词要用复数。例如: Behind the wall stand a house and a garage.在大墙的后面有...

A and B属于复数,意为A加B或A和B,后面用are。

主谓一致原则 a and b are doing…主语是两个人或两样东西,所以谓语动词be用are a with b is doing…=a is doing...with b with连接的词做主语时谓语动词遵循就远原则,即与with前的主语一致,这里be动词用is,那a一定是第三人称单数

两个都是动作,合起来整体看还是动作,英语就当做一个整体看,就是一件事,即单三人称代词it。it 和 is 配合。

你好。 关键看主语。 比方说,一本书在A和B之间,则为 A book is between A and B。 一些书在A和B之间,则为Some books are between A and B。

你好,正确答案应该是:B There be 句型用 就近原则 靠近 be 动词的是a pencil ,是单数 应该用 is 如果换个位置,应该用 are There are some pens and a pencil in the pencil case .

为您解答 呃。。。不给全句怎么知道,这个要看主语的。请给完整

A: Hey Professor B, do you know a student named Kate in Professor C's class? B: Say hi back, Professor A. Of course, I know. I mean how can I not know Kate. When it comes to Kate, Professor C will certainly get on her hobbyhors...

what is 就是单数啊 is 是be动词的单数形式,difference也是用的单数。 what are是复数,are是be动词的复数形式,differences也是用的复数。
