Grammar
used to意为“过去常常”，用于表示过去习惯性的动作或存在的状态（强调与现在的对比，暗示现在不做了）。其中to为不定式符号，后跟动词原形。used to只用于一般过去时态，没有人称和数的变化。
一、used to的用法
e.g. Tom used to be very thin, but now he’s big and strong.
汤姆以前很瘦，但现在他又高又
壮。
二、used to的句式变化
1. 否定句
used not
主语 + to do sth.
didn’t use
e.g. Mike used not to study hard.
= Mike didn’t use to study hard.
迈克过去不努力学习。
2. 一般疑问句
Did+ 主语 + use + to do…
答语：Yes, sb. did. / No, sb. didn’t.
e.g. —Did you use to go to museums
你以前常去博物馆吗？
—Yes, I did. / No, I didn’t.
是的。/ 不是。
3. 反意疑问句
主句+ didn’t+人称代词？
e.g. Your brother used to have noodles
for breakfast, didn’t he
你哥哥过去早餐常吃面条，不是
吗？
(四) used to 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：He always used to be late for class.
他过去常常上课迟到。
(五) used to可以用在there be结构中表示“过去经常有”的意思。
There used to be
There used to be a lot of teachers in the school.
100 years ago, there used to be a beautiful village
in the country
There used to be a clever old man in the village.
Did he use to wear glasses
used to do sth.
表示过去习惯性的动作或存在的状态。
to后跟动词原形，只用于一般过去时态。
辨 析
2. be used to + n. /pron./doing
意为“习惯于……”，to是介词，后接
名词、代词或动名词。可用于各种
时态。
3. get/become used to sth./doing sth.
意为“逐渐习惯于……”，强调这一习
惯的过程，to是介词。
4. be used to do
意为“被用来做……”，被动语态结构，to后跟动词原形。
5. be used for doing sth.
意为“被用来……”，介词for表示功能、用途。
