助动词 dodoes 的用法
助动词 do/does 的用法 例句：Do you want any breakfast ,Paul ? How much juice do you want ? I don’t want any coffee, but I want some tea . 这里，我们看这几个句子既出现了实义动词want,又出现了do，仔细观察发现：这些句子都是在的帮助下形成的，因此称这个do为助动词。 助动词在句中不能独立使用作谓语，并通常用于主语为第一人称、第二人称或者第三人称复数的疑问句和否定句中。 【第三人称复数：人称代词分为第一人称、第二人称、第三人称。单数是指一个人，多于一个人就为复数。We(我们)、You(你们)、They(他们/她们/它们) 分别是第一人称、第二人称、第三人称的复数形式。】 1、将一个肯定句变为疑问句时，应将do/does放在主语的前面，实义动词用原形。 例句：I/ We / You want some yoghurt. →Do you want any yoghurt ? William wants some beer.→Does William want any beer? She likes that one. →Does she like that one? 2、变否定句时则要在句中谓语动词的前面加do not(don’t)或doesn’t。 例句：I don’t want any coffee, but I want some tea . She doesn’t like that one. →Doesn’t she like that one?
