Do 和 Does:疑问句与否定句

在一般现在时中,疑问句和否定句需要助动词do。 - do / don't用于I, you, we, they及复数名词:Do you live here?(你住在这里吗?)I don't eat meat.(我不吃肉。) - does / doesn't用于he, she, it及单数名词:Does she speak French?(她会说法语吗?)He doesn't drive.(他不开车。) 完整形式是do not和does not;在口语中我们通常说don't和doesn't。 do或does之后,主要动词保持原形,不加-s:Does she speak?(不是speaks),He doesn't eat meat(不是eats)。 疑问词放在最前面:Where does your sister work? How often do you go to the gym?(你姐姐在哪里工作?你多久去一次健身房?) 在疑问句和否定句中,动词be不使用do:Are you ready? She isn't here.
