这个问题我会，虽然本人英语口语不是很好，但是对英语四六级词汇还是很熟悉的~下面给大家从三个方面具体解释一下：
【含义】
someone作为代词,意为某人、重要人物,相当于第三人称,后接谓语动词单数;
someone：某人，重要人物。
someone：someone常用在肯定句中。
anyone作为代词,意为任何人、随便哪个人,常用在否定句和疑问句中。
anyone：任何人，随便哪个人。
anyone：anyone则常用在否定句和疑问句中。
【用法】
1、someone：中文意思是“某人”。英文中可做名词，代词。someone相当于第三人称，所以后接谓语动词单数。
2、anyone：anyone指“任何人”，不指“任何一个”，any one指“任何一个”，但是有时也指“任何人”，现在比较不普遍那样说，anyone不能同one或one's同时使用，如Ifanyonecomes，ask him to wait里面的him不可替换成one，anybody比anyone更加普遍，在口语中出现比较频繁。
【例句】
anyone
