used to和 be used to的区别谁能给我解释下
一.Used to 是情态动词,意思是“过去常常”.它只有过去式,用于各种人称的单复数,表示过去存在但现在已经停止的情况或习惯.其后接不定式如:I used to be a worker.我原来是个工人.(but I am not a worker now.)但现在不是了 He used to get up early in the moring.他以前早上起的很早 (But he doesn’t get up early now.)但是他现在不早起了 1.肯定式:use to 的肯定形式就是他本身,如上例.再如:They use to be good friends.(but they not good friends now.)他们原来是好朋友(但现在不是了) There used to be a tall tree in front of the house.(but there isn’t a tall tree in front of the house now.)以前房子前面有很高的树(但现在没有了) 2.否定式:used to 的否定形式是used not to ,也可以用use(d)n’t to (其中读作[ ])或didn’t used to.如:“你过去不喜欢吃羊肉“一句可说成:You use(d) n’t to like mutton.(口语) You used not to like mutton 羊肉(书面语) You didn’t use to like mutton.(口语) 若要说:“你过去从来不吃羊肉”可说:You never used to like mutton.3.疑问式:use to 的疑问式是“Used+主语+to…?”也可以用“Did+主语+to…?”或“Didn’t+主语+use to…?”.如:Used she to like Tom?她过去喜欢汤姆?Did she use to like Tom?Use(d)n’t she to like Tom?难道他过去不喜欢汤姆吗?Didn’t she use to like Tom?注意答案中的用法:――Used be to go to market every Sunday?他以前每周日都去市场吗?――No,he usedn’to.(Yes,he used to.) ――Did you used to play football at school?你原来在学校玩儿足球吗?――Yes,I did.(No,I didn’t) 4.反义疑问句:在反义疑问句可用use(d)或did,并视其情况而定肯定式或否定式.如:He used to play cards a lot,use(d)n’t he (或didn’t he 他原来很爱玩儿牌,不是吗?There used to be a lot of trees around the place,use(d)n’t there (或 didn’t there 以及weren’t there)?原来这周围有很多树,不是吗?5.副词的位置:和used to 连用的副词可放在used之前或之后(在非正式文体中,常放在used之前)如:I always used to be afraid of dogs.我过去总是怕狗 I used always to be afraid of dogs.6.used to 和 would的区别:used to也可表示过去经常性的行为,不强调与现在事实或情况的对比,此时,used to 和 would 可以通用.如:When we were children we used to (would) go skating every winter.我们小的时候,每年冬天都去滑冰.但是需注意:used to 可用来谈动作,也可以用来谈情况;而would只能用来表示动作的重复,如:I used to have an old Rolls Royce.过去我有一辆旧的罗斯莱斯小轿车.(该句不能说:I would…) 还有:would 和 used to 均不能用来表示某事发生的次数.如:“我小时候,我们去过非洲六次”,只能说:We went to Africa six times when I was a child.(不能说We used to(或would) go…) 请注意:以上used 之前的主语都是人而不是物.二.be used to 1. Be used to意为“习惯”,其中used是形容词.to是介词,其后可按名词或动名词,往往表示一种心理状态.其系动词除了be以外,还可以用get或become,均用于各种状态.如:I am used to noise.我对噪音习惯了 You will soon get used to driving on the left.你不久就会习惯在昨侧开车了 Are you used to hard work now?You will soon used to it,你现在习惯努力工作了吗?你不久就会习惯的 I am not used to being spoken to like that.用那样的态度和我说话,我是看不惯的.You can say what you like!I am used to being criticized.你爱说什么就说什么好了!我已经习惯于受批评乐了.请注意:be used to (习惯于)的这种用法,其主语是人而不是物.2. Be used to 还可以是动词use的被动式结构,意为“被用来……”.注意:此时,其主语一般是人而不是物.如:This machine is used to pump water.这种及其是用来抽水的.This knife is used to cut bread.这把刀是用来切面包的.And all this beautiful silk would be used to used to weave colourful clouds in heacen.所有这些美丽的蚕丝都将用来织天上的彩云.
