Yes,Idid./No,Ididn’t.Didheusetowearglasses?Yes,hedid./No,hedidn’t.GrammarFocususedto是一個(gè)固定結(jié)構(gòu)，它的意思是“過(guò)去經(jīng)常、以前常常”，它的后面用動(dòng)詞原形，它表示過(guò)去存在某種狀態(tài)或者過(guò)去的某種經(jīng)常性、習(xí)慣性的行為或者動(dòng)作，并意味著這種動(dòng)作目前已經(jīng)不存在，所以它只能用一般過(guò)去時(shí)，不能用現(xiàn)在時(shí)態(tài)?！皍sedto”

B)主語(yǔ)＋usednotto＋動(dòng)詞原形

第一種否定句型，就是把used當(dāng)作實(shí)義動(dòng)詞來(lái)看，所以變否定句要用助動(dòng)詞did；第二種否定句是把used當(dāng)作情態(tài)動(dòng)詞，變否定句直接在used后面加not即可，usednot可以縮寫成usedn’t或usen’t。美式英語(yǔ)通常用A種形式，英式英語(yǔ)常用B種形式。例如：

Youdidn'tusetodrink.Sheusedtosmokealot.Didsheusetosmokealot?Usedshetosmokealot?Didyoursisterusetobequiet?Usedto的一般疑問(wèn)句形式(四)usedto的狀語(yǔ)可以用副詞always，often，sometimes等，但是仍然是過(guò)去的習(xí)慣，不是指現(xiàn)在的習(xí)慣，所以不能用一般現(xiàn)在時(shí)。例如：Healwaysusedtobelateforclass.他過(guò)去常常上課遲到。(五)usedto可以用在therebe結(jié)構(gòu)中表示“過(guò)去經(jīng)常有”的意思。Thereusedtobe
