5、o是不定式符号02 二、掌握used to用法。used to do sth. 过去常常做某事，它没有人称和数的变化。其用法有三：1. 表示过去存在而今不复存在的习惯行为或状态，意为：“过去常常”，其中to不定式符号，后接动词原形，表示今昔对比。如：I used to walk to school, but now I am used to taking the school bus to school.我过去常常走路上学，但现在我习惯坐校车上学。2. used to 与there be 结构连用，表示“过去存在的状态”，而现在不存在此类状态了。如：There used to be a lot
6、 of trees here.这里原来有许多树。(意味着现在没有了)3. used to 与always， often， sometimes等频度副词连用时，并非表示现在的动作或现在的习惯，仍表示过去习惯、过去经常反复发生的动作或存在的状态。如：She used to write to her father with pens. 她过去经常用钢笔写信给她父亲。03 三、掌握used to 的句子结构。1. used to的肯定句结构主语+used to+动词原形如：I used to go to the cinema, but I never have time now. 我过去经常去看电影，
7、但现在没有时间了。2. used to的否定句结构，其否定结构有两种形式。 主语+did not use to+动词原形，这种否定句型，就是把used当做实义动词来看，所以变否定句要用助动词did，是美式英语用法。如：You used to drink. You didnt use to drink. 主语+used not to+动词原形，这种否定句是把used当做情态动词，变否定句直接在used后面加not即可，used not可以缩写成usednt，是英式英语用法。如：The shop used to open on Sungdays. The shop usednt to open o
8、n Sunday.3. used to的一般疑问句结构，其一般疑问句有两种形式。 Did+主语+use to+动词原形?这种一般疑问句，就是把used当做实义动词来看，所以变一般疑问句时要用助动词did，是美式英语用法。如：I used to go swimming in the river when I was young.Did you use to go swimming in the river when you were young? Used+主语+to+动词原形?这种一般疑问句是把used当做情态动词，所以变一般疑问句时，直接把used提到句首，是英式英语用法。如：He used
9、 to go to school by bike. Used he go to school by bike?4. used to 的肯定和否定回答结构。used to用于省略句时，肯定式保留to，否定式不保留to。如： Used you play basketball? 你过去常打篮球吗?Yes, I used to.(No, I usednt.) 是的，经常打。(不，不常打。)5. used to的反意疑问句，其反意疑问句有两种形式。 在附加疑问部分中借助于助动词did构成，这种反意疑问句，就是把used当做实义动词来看，所以变反意疑问句时要用助动词did，是美式英语用法。如：She us
10、ed to go to work by bus, didnt she?She didnt use to do it, did she? 在附加疑问部分中直接使用usednt。这种反意疑问句是把used当做情态动词，所以变反意疑问句时，直接用used，是英式英语用法。如：There used to be a bookshop here, usednt there?6. used to通常不能与表示次数(如twice, three times 等)或一段时间(如three months, five years等)的词连用。如： 我去过巴黎3次。正：I went to Paris three tim
11、es. 误：I used to go to Paris three times04四、掌握易混词组拓展辨析。used to do sth.; be used to doing sth.; be used to do sth.; be used for doing sth.; be used as sth. be used by sb.1. used to do sth. 意为“过去经常做某事”，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 used to live in Paris. 他过去一直住在巴黎。2. be used to doing sth. 意为
12、“习惯于做某事”，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，用get, become 等代替动词be。如：He is used to looking after himself. 他已习惯于自己照顾自己。3. be used to do sth. 意思是“被用来做某事”，其中to是不定式符号，所以其后要接动词原形，等于be used for doing sth.。如：Knives are used to cut things.=Knives are used for cutting things.小刀是用来切东西的。4. be used as s
13、th. 意思是“被作为用”。如：This book can be used as a text book. 这本书可以被当作课本用。 。5. be used by sb. 意思是“被某人使用”。如：The machine is used by workers. 这台机器是工人们使用的。English is used by people in many countries. 英语被许多国家的人使用。05 五、掌握used to与would的不同用法1. 两者都表示过去的习惯，当表示过去习惯性的动作时，可互换。如： When we were children we would used to go
14、 skating every winter. 我们小时候，每年冬天都去溜冰。2. 若表示过去持续的状态，通常只用used to，不用would。如：He used to like you. 他原来还是喜欢你的。He is not what he used to be. 他已不是从前的他了。3. 若要强调过去与现在的对比，也通常只用used to。如：I dont smoke these days, but I used to. 我现在不抽烟，但我以前是抽的。I used to drive to work, but now I cycle. 过去我常驾车上班，但我现在骑自行车 。即时练习：( )
15、1. People_ think that the sun goes round the earth.A.would B. are used to C. used to D. are used( )2. There _ a lot of birds in this area.A. was used to be B. used to C. used to be D. used to have( )3. She used to _ with her parents, but now she is used to _ with her classmates at school.A.live; liv

17、to五分钟搞懂used to的用法区分基本用法used to意为“过去常常，过去是”，其后跟动词原形，表示过去存在的某种状态或过去某种经常性、习惯性的行为或动作，并意味着这种情况目前已不复存在，侧重于过去与现在的对比。used无人称和时态的变化。We used to go there every year.我们以往每年都去那里。I used to get up at six in the morning ,but I usually get up at half past five now.我过去常常早上六点起床，但是现在我通常五点半起床。Tina is not what she used t
18、o be .蒂娜已经不再是过去的她了。The old man used to be an excellent player.那位老人曾是一名出色的运动员。否定句式used to 的否定形式是didnt use to 或used not to ,后者可缩写成usednt to ,在口语中常用didnt use to 进行否定。She didnt use to /used not to /usednt to play computer games .她过去不常玩电脑游戏。一般疑问句式used to 变一般疑问句可以用Did sb.use to .?或Used sb. to .?Did you us
19、e to /Used you to play football?你以前经常踢足球吗?Didnt your uncle use to /Usednt your uncle to live in Beijing?你叔叔过去不是一直住在北京吗?反意疑问句used to 在变反意疑问句时，它的附加问句部分可以用didnt 或usednt .Martin used to go out for a walk after supper,didnt /usednt he?马丁过去常常晚饭后出去散步，是不是?Yes ,he did ./Yes ,he used to .是的，他过去是这样。No,he didnt
20、 ./No, he usednt to .不是，他过去不是这样。英语中的【used to】和【 use to】用法的区别在哪里呢?used to和be used to的用法与区别be used to为被动语态。意为“被用来”，为动词不定式符号，其后跟动词原形。例如：Golden trumpets are used to express public opinion here.这儿金喇叭是用来表达公共舆论的。Bamboo can be used to carry water.竹子可用来输水。【注意】若“used to”后接动词原形，意思是“过去常常”，表示过去经常发生的动作(或存在的状态)现在已
21、不再发生(或存在)了。例如：People used to think the sun travelled round the earth.人们过去曾经认为太阳绕地球转动。(暗指人们现在并不这样认为了。)used to的否定式可用didnt use to,或used not to(缩写为usednt to或usent to读音为ju:snt。若“be used to+名词或v-ing”意思是“习惯于”。试比较：He used to walk to school.他过去总是步行到校。He is used to walking to school. 他现在习惯于步行上学了。值得注意的是：1)used to只用于过去时，不能用于别的时态;be used to则可用于各种时态。例如：He is (was, will be, has been, etc.) used to walking to school.2)be used to 中的be可以用 get, become, grow代替，用这些动词构成的动词词组表示由不习惯到习惯的过程。例如：Youll soon get used to the life in the countryside.你很快就会习惯乡下的生活的。Used to 用法小结
