used to do的一些区别

used to do、be used to do与be used to doing sth.的用法详解used to do 过去常常做某事 be used to doing 习惯于做某事 be used to do sth 被用来做某事 1. used to的一般疑问句有两种构成方法: 1)将used提前至句首,结构为:Used + 主语+ to do sth...? 2)将did提前至句首,结构为:Did + 主语+ use to do sth...? 例如: Used he to get up early? = Did he use to get up early? 2. used to的反义疑问句有两种构成方法,例如: 1)He used to smoke,didn't he? 2)They usedn't to like opera,did they? 3.同样,其否定句也有两种构成方式: 1)直接在used后面加上not,也可一起缩写成usedn't. 结构为:主语+ used not to do sth... 或主语+ usedn't to do sth... 2)借助于助动词didn't,其结构为: 主语+ didn't use to do sth.... 例如: He used not to get up early. = He usedn't to get up early. = He didn't use to get up early. 4、be(get,become)used to结构在意义上相当于accustomed to“习惯于”,从形态上看,used是个分词型形容词,to是介词,因此后面只能跟名词、代词或动名词。例如: 1)They got used to living in the countryside.他们已习惯于住在农村。 2)I've got used to being a vegetarian.我已经习惯吃素食。 3)He is used to hard work.他习惯于艰苦工作。 5、be used to表示“习惯于某事”的状态,而get used to则表示由“不习惯”到“习惯于”这一动态的过程,意思是:“(变得)习惯于”;“开始习惯于”。试比较: He was used to the cold weather after he lived there for two years. 在那里住两年后,他已习惯了寒冷的天气。 I think it is a bit difficult for you to get used to the humid weather here. 我想,让你习惯于这里潮湿而炎热的天气有点困难。 You'll soon get used to living in the country. 很快你就会习惯于住在乡下了。 6、当主语是物的时候是指被用来做某事,be used to是动词use的被动语态,在这种结构里,to是不定式符号。例如: A metal bar was used to force the door open. 用金属棒把门撬开。

usedto与beusedto用法辨析

used to与be used to用法辨析 1. be used 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be。如: He is used to looking after himself. 他已习惯于自己照顾自己。 I’m sure I’ll get used to the hard work. 我相信我会习惯这艰苦工作的。 注:be used to 有时可能是动词use 的被动语态结构(此时意为“被用来”,其中的to 为不定式符号,其后要接动词原形)。如: A hammer is used to drive in nails. 锤子是用来钉钉子的。 2. 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(不能接动名词)。 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(如twice, three times 等)或一段时间(如three months, five years 等)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(d) to be a teacher 你过去是当老师的吗 They didn’t use(d) to live here. 他们过去没住在这儿。 There used to be a cinema here, use(d)n’t there 往日这里曾有家电影院,是吗

B) Used+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 use to go swimming in the river when you were young? 你小时候经常在河里游泳吗? Used he go to school by bike? 他过去骑车上学吗? 4、used to用于省略句时,肯定式保留to,否定式不保留to。例如: ——Used you play basketball? 你过去常打篮球吗? ——Yes, I used to.(No,I usedn't.) 是的,经常打。(不,不常打。) 二、区分be used to与used to 1、be used 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 used to looking after himself. 他已习惯于自己照顾自己。 I’m sure I’ll get used to the hard work. 我相信我会习惯这艰苦工作的。 2、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(不能接动名词)。如: He used to live in Paris. 他过去一直住在巴黎。 I always used [used always] to be afraid of dogs. 我过去总是怕狗。 三、used to与would的不同用法
