used 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。如：
He used to live in Paris. 他过去一直住在巴黎。
注：used to 通常不能与表示具体次数或一段时间的词或短语连用，但是它却可以与 always, often 等表示经常性意义的副词连用。如：
正：I went to Paris three times. 我去过巴黎 3 次。
误：I used to go to Paris three times.
正：I lived in the country for three years. 我在乡下住过 3 年。
误：I used to live in the country for three years.
正：I always used [used always] to be afraid of dogs. 我过去总是怕狗。
used to 构成否定式和疑问式时通常有两种方式：即借助助动词did 或直接将 used 用作助动词。如：
He usedn't [didn't use] to come. 他过去不常来。
You used to go there, usedn't [didn't] you? 你过去常到那儿去，是吗?
另外，有时也可见到以下这样的否定式和疑问式，但不是很普通：
Did you use to be a teacher? 你过去是当老师的吗?
They didn't use to live here. 他们过去没住在这儿。
There used to be a cinema here, usen't there? 往日这里曾有家电影院，是吗?
有used的句子怎么变否定句
以下是used to构成疑问和否定的详细讲解和例句：used to作为情态动词，可直接在used后加not构成否定式，直接将used置于句首构成疑问式，但与一般的情态动词不同的，它也可像普通动词那样借助助动词did构成否定式和疑问式：He usedn't 〔didn't use〕 to come. 他过去不常来。
You used to go there, usedn't 〔didn't〕 you？ 你过去常到那儿去，是吗？Where did you use to live？ 你过去是住哪儿的？【注】在现代英语中，used to的否定式和疑问式通常借助助动词did构成（特别是在口语和非正式文体中），而直接将used作为助动词用通常被认为是非常正统或过时的用法。
然而有趣的是，有时还可见到以下这种混合形式：Did you used to be a teacher？ 你过去是当老师的吗？They didn't used to live here. 他们过去没住在这儿。

used to 的短语 there be句型
There be句型的用法一、构成：There be ...句型表示的是 “某处有（存在）某人或某物”，其结构为There be+名词+地点状语。
例如：There are fifty-two students in our class.There is a pencil in my pencil-case.There was an old house by the river five years ago.二、各种句式：否定句：There be句型否定句式的构成和含有be动词的其它句型一样，在be后加上“not”。
也可用“no”来表示。
即：no + n.（名词）= not a\an\any + n.（名词）。
注意：no + n.（可数名词单数）= not a\an + n.（可数名词单数）；no + n.（可数名词复数）= not any + n.（可数名词复数）；no + n.（不可数名词）= not any + n.（不可数名词）。
例如：There is an orange in her bag.→There isn't an orange in her bag.→There is no orange in her bag.There are some oranges in her bag.→There aren't any oranges in her bag.→There are no oranges in her bag.There is some juice in the bottle.→There isn't any juice in the bottle.→There is no juice in the bottle. 一般疑问句：There be结构的一般疑问句变化只需把be动词移到句首，再在句尾加上问号即可。
例如：There is some money in her handbag. → Is there any money in her handbag？ （疑问句和否定句中，some改为any, something改为anything.）There is something new in today's newspaper.→There isn't anything new in today's newspaper.→Is there anything new in today's newspaper？特殊疑问句： There be句型的特殊疑问句有以下三种形式：①对主语提问：当主语是人时，用 “Who's + 介词短语？”；当主语是物时，用 “What's + 介词短语？”。
其中there在口语中常常省略。
注意：无论原句的主语是单数还是复数，对其提问时一般都用be的单数形式（回答时却要根据实际情况来决定）。
如： There is a bird in the tree.→What's in the tree? There are some bikes over there. →What's over there?There is a little girl in the room. →Who is in the room？②对地点状语提问：用 “Where is \ are + 主语？”表示（注意其答语变化）：例如： There is a computer in my office.→ Where is the computer? ----It's in my office. There are four children in the classroom.→Where are the four children？—They' re in the classroom. ③对数量提问：一般有两种提问方式：如果主语是可数名词，无论是单数还是复数，都用“How many +可数名词复数 + are there + 介词短语？”表示：There are twelve months in a year.→How many months are there in a year?There is only one book in my bag.→ How many books are there in your bag?There is a cat in the box.→ How many cats are there in the box？如果主语是不可数名词，则用“ How much + 不可数名词 + is there + 介词短语？”表示：There is some money in my purse. How much money is there in your purse？反意疑问句：There be或There加其它动词，其反意疑问句一律用…there？ 例如：There is a beautiful girl in the garden, isn't there?There used to be no school here, used there \did there？三、注意事项：1. There be句型中be动词的形式要和其后的主语在人称和数上保持一致。
如果句子的主语是单数的可数名词，或是不可数名词，be动词用“is”“was”。
例如：There is a basketball in the box.There is a little milk in the glass.如果句子的主语是复数名词，be动词就用“are” “were”。
例如：There are many birds in the tree.There were many people in the street yesterday.如果有两个或两个以上的名词作主语，be动词要和最靠近它的那个主语在数上保持一致，也就是我们常说的“就近原则”。
例如：There is an orange and some bananas in the basket. There are some bananas and an orange in the basket. 2. There与be中间可插入一些表推测的情态动词、表时态的短语和一些动词短语 （如和将来时be going to\ will、现在完成时 have\has + pp. 、used to结构等连用，注意其构成形式，这一内容在我们日常练习中经常出现错误，是一难点，也是历年中考试题中的一个考点.）。
例如：There must be a pen in the box.There happened to be some money in my pocket.There is going to be a meeting tonight.There has been a big tree on the top of the hill.There used to be a church across from the bank. 3. There be句型和have\has的区别：There be句型表示 “存在有”， have\has表示 “拥有” “所有”，两者不能同时使用.例如：桌子上有三本书. There are three books on the desk.我有三本书. I have three books. 4. There be + 主语 + doing +介词短语. 例如：There is a truck collecting rubish outside.There is a wallet lying on the ground.四、练习：Choose the best answers.1. There isn't _____water in the glass. Let's go and get some.A. many B. lots C. any D. some2. There ___a lot of news about Zhang Ziyi on TV last night. A. was B. had C. is D. were3. There ____ many changes in the village recently. A. is B. are C. have been D. to ...
