everyone用单数还是复数（为什么everyone是第三人称单数）

"Everyone" 通常被视为单数形式，尽管它代表了一群人。在语法上，它被视为单数主语，因此谓语动词应该是单数形式。例如：

Everyone is here.（每个人都在这里。）

However, in some cases, "everyone" can be used with a plural verb when referring to a group of people as a whole. This is more common in informal or conversational English. For example:

Everyone are wearing hats.（大家都戴着帽子。）

It's important to note that this usage may not be accepted in all formal contexts, so it's best to use "everyone" with a singular verb in formal writing.
