Yes,Idid./No,Ididn’t.Didheusetowearglasses?Yes,hedid./No,hedidn’t.GrammarFocususedto是一个固定结构，它的意思是“过去经常、以前常常”，它的后面用动词原形，它表示过去存在某种状态或者过去的某种经常性、习惯性的行为或者动作，并意味着这种动作目前已经不存在，所以它只能用一般过去时，不能用现在时态。“usedto”

usedto+dosth.“过去常常”表示过去习惯性的动作或状态，但如今已不存在。I

readnewspapersafterbreakfast.

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：

Youdidn'tusetodrink.Sheusedtosmokealot.Didsheusetosmokealot?Usedshetosmokealot?Didyoursisterusetobequiet?Usedto的一般疑问句形式(四)usedto的状语可以用副词always，often，sometimes等，但是仍然是过去的习惯，不是指现在的习惯，所以不能用一般现在时。例如：Healwaysusedtobelateforclass.他过去常常上课迟到。(五)usedto可以用在therebe结构中表示“过去经常有”的意思。Thereusedtobe
