例如：

havetimenow.;B)主语＋usednotto＋动词原形......

第一种否定句型，就是把used当作实义动词来看，所以变否定句要用助动词did；第二种否定句是把used当作情态动词，变否定句直接在used后面加not即可，usednot可以缩写成usedn’t或usen’t。美式英语通常用A种形式，英式英语常用B种形式。例如：

Youdidntusetodrink.;A)Did＋主语＋useto＋动词原形...？

B)Used＋主语＋to＋动词原形...？美式英语通常用A种形式，英式英语用B种形式。例如：

Didyouusetogoswimmingintheriverwhenyouwereyoung?;注：usedto可以用在therebe结构中表示“过去经常有”的意思。
