我们学习到了ud to do sth. 意思是“过去常常做某事”,表示过去经常做或一直做而现在不做,它只用于过去时态。
今天,我们就来对ud to的用法注意事项做一次详细讲解。
一、ud to的基本用法:
1、ud to的肯定句结构
主语+ud to+动词原形……例如:
I ud to go to the cinema, but I never have time now.
我过去经常去看电影,但现在没有时间了。
2、ud to的否定句结构
A) 主语+did not u to+动词原形……
B) 主语+ud not to+动词原形……
第一种否定句型,就是把ud当做实义动词来看,所以变否定句要用助动词did;第二种否定句是把ud当做情态动词,变否定句直接在ud后面加not即可,ud not可以缩写成udn't或un't。美式英语通常用A种形式,英式英语常用B种形式。例如:
You didn't u to drink.
你过去不喝酒。
The shop udn't to open on Sundays.
过去这家商店星期天不营业。
3、ud to的一般疑问句结构
A) Did+主语+u to+动词原形……?
B) Ud+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:
Did you u to go swimming in the river when you were young?
你小时候经常在河里游泳吗?
mocking bird
Ud he go to school by bike?
他过去骑车上学吗?
4、ud to用于省略句时,肯定式保留to,否定式不保留to。例如:
—— Ud you play basketball?
你过去常打篮球吗?
——Yes, I ud to.(No,I udn't.)
是的,经常打。(不,不常打。)
二、区分be ud to与ud to
1、be ud to 意为“习惯于”,其中的 to 是介词,所以其后要接名词或动名词(不能接动词原形);若要强调从不习惯到习惯的过程,可用 get, become 等代替动词 get, become be。如:
He is ud to looking after himlf.
他已习惯于自己照顾自己。
I’m sure I’ll get ud to the hard work.
我相信我会习惯这艰苦工作的。
2、ud to 意为“过去经常”,其中的 to 是不定式符号,而不是介词,所以其后只接动词原形(不能接动名词)。如:
He ud to live in Paris.
他过去一直住在巴黎。
I always ud [ud always] to be afraid of dogs.
我过去总是怕狗。
三、ud to与would的不同用法
1、ud to可表示过去的习惯动作或状态;而would只表示过去的习惯动作,不接表示认
语音信箱识或状态的动词。例如:
Kate ud to be a model worker. journalist
凯特曾是一位模范工人。
(例句中的ud to不能用would代替。因为所用的动词都是静态动词,只是说明一种事实或状态。)
2、ud to表过去与现在或过去某时与后来的情况不同,强调“现在已无此习惯了”;而would只表示过去的情况,与现在无关。只表示说话人对过去的一种回想心情。例如:
When he was young, he would smoke a lot.
他年轻时,总是吸很多烟。(现在可能吸,也可能不吸了。)
(句中的ud to不能用would代替,因为would不含有“现在不再这样了”之意。)
3、ud to泛指过去的习惯性动作或状态,可无时间状语,不能与表示一段时间的状语连用;而would表示过去的习惯性动作时,往往要带有时间状语,常与often, frequently, sometimes, for hours等连用。例如:
He would sit for hours, deeply thinking.
他过去经常一坐好几个小时沉思着。
People___ think that the sun went round the earth.
A. would B. are ud to C. ud to D. are ud
(1) ud to do sth. 过去常常……(现在已不如此)
We ud to grow beautiful ros.
注意:否定句和疑问句有两种
You udn’t to make that mistake.

She didn't u(d) to do it, did she?
You ud to smoke a pipe, didn't you? / u(d) n't you?
【区别】
(2) be / get / become ud to + n. / doing 习惯于
I have always been ud to hard work.
He got ud to living in the country.
(3) be ud to do 被用来做……
This knife is ud to cut bread.
表示“过去常常……”时,ud to与would区别:
(1) would 只强调“过去常常……”,ud to 说明现在不是如此。
The old woman would sit there for hours doing nothing.
(2) would 只接行为动词,ud to 可接行为动词和表状态的词。如:be, like, know, have。There ud to be a temple at the foot of the mountain

ud to的用法
ud to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。
1. 它的陈述句的肯定形式:主语+ud to+动词原形。
例如:I ud to play with my friends after school. 过去放学后我常常和朋友们一起玩。
2. 它的否定形式:主语+didn’t+u to+动词原形。
例如:You didn’t u to like pop songs. 你过去常常不喜欢流行歌曲。
3. 它的一般疑问句形式:Did+主语+u to+动词原形+其他?
例如:Did your sister u to be quiet? 你的妹妹过去常常是很安静吗?
4. ud 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 ud to be late for class. 他过去常常上课迟到。
5. ud to可以用在there be结构中表示“过去经常有”的意思。
