当句中有and时怎样判断它是属于同一概念如：The poet and writer has come

当句中有and时怎样判断它是属于同一概念如：The poet and writer has come

我的经验是根据后面的动词来判断。像你例句中的has，而不是have.
has是单数的，have是复数。
用has就是一个人，have就是2个人或多个人了。
希望可以帮到你

你好！ 看有几个冠词，一个冠词是一个人， 如：The poet and writer 这人是诗人兼作家 The poet and the writer 诗人和作家，是两个人 仅代表个人观点，不喜勿喷，谢谢。

the +名词+名词一个人两重身份，谓语用单数

the poet and the writer 就和他不一样 the特指 the(poet and writer)一个整体
