used to do sth疑问形式:used……to do(或did……use to do),否定形式:used not to do(或did not use to do) be used to doing sth疑问形式:be……used to doing,否定形式:be not used to doing

used to do sth. 句型表示“过去常常,过去习惯.”表示过去的某种习惯(过去经常反复发生的动作或状态). 否定式:used not to do sth. 疑问句:used sb. to do sth.? Did sb. use to do sth.?

used to 用於叙述过去的习惯,比如说 I used to go to the park with my grandma. 我以前常常和我的奶奶去公园.(但现在没有了) to get used + to / be used to 后面需接V-ing 表示习惯於某事,后面的 to是介系词,所以接在兔之后的动词必须变成

就是把 used to 当情态动词否定式:主语 used not to do sth. 疑问句:used sb. to do sth.?所以反义疑问句就是主语 used to do,usedn't you? (used not可缩写为usedn't或usen't.)

你好!be uesd to doing 习惯做某事=get uesd to doing uesd to do sth.过去经常做某事如有疑问,请追问.

used to其实相当于一个副词的作用,表示过去常常,不存在否定的形式.

used 一分为二第一种 把used 看成情态动词 那么否定就是直接在情态动词后面加not, 疑问就是把used 提前否定形式就是 used not to do =usdn't to do疑问形式就是usedto do第二种 把used 看成是use的过去式,也就是句子为一般过去时那么否定就是didn't use to do (一般过去时的否定就是did not +动词原形)疑问形式就是 diduse to do (一般过去时的助动词did提前,那么use应该用原形)

used to do sth. 句型表示“过去常常,过去习惯做某事. (过去经常反复发生的动作或状态). 否定式:used not to do sth. e.g. I used not to live there when I was a child. I didn't use to live there when I was a child.(口语中:didn't use to do sth

否定句可以用以下的三种方法来表示: ① I didn't use to watch television as a child ② I used not to watch television as a child ⑶ I never used to watch television as a child. ①是最经常使用的形式. ②是作为书面语最一般的形式,但是在口语中并不常用. ⑶是在书面语和口语中都很常用的表达.
