be able to用法归纳
able. adj. 能够的,有能力的,有才干的,干练的 变形:比较级:abler; 最高级:ablest. 例句: Chantal was lucky to be able to salvage her career. 尚塔尔能保住她的事业算是走了运。 扩展资料 able用法: able可以用作形容词: able是具有评价意义的形容词,用于表示人的某种特点。able有两层含义:一是“能够”(尤用于不使用can或could的时态中); 二是“能干”。前者指因具有体力、智力、技能、时间、财力或机遇等而具有某种能力,通常也指应付一件事情的能力,有时还可表示“称职的”。后者指具有某种才干,即在智力、技巧、知识或能力等方面超过平均水平,胜人一筹,不仅指聪明,也含有经受过实际锻炼之意。 able作“能够…的”解时,一般用作表语,其后多接动词不定式(不接“of+动名词”),也可接介词短语。作“有能力的.,能干的”解时,可用作定语、表语或补语。able接动词不定式时,其主语、able及动词不定式均存在逻辑上的主谓关系。 able用作表语时主语通常是人,也可为动物,偶尔也可为事物(多见于科技文体)。able用作定语时主要修饰人,也可修饰人所做的事,指事情做得好或做得成功。这样用时也暗示做成该事的人有才能。 able用作形容词的用法例句: We shall be able to deal with all sorts of problem.我们应该能够应付各种困难。 She bet me 20 that I wouldn"t be able to give up smoking.她和我打20英镑的赌,说我戒不了烟。 Free will makes us able to choose our way of life.自由的意志使我们可以选择自己的生活方式。2023-07-28 18:22:511
be able to 等于be 什么 of
be able to =be capable of。able,capable 这一对词都是形容词,又都含有“能够”、“能干”之意,但涵义和使用场合有所不同,大致有如下几点区别: (一)在用作定语表示“能干的”意味时,able所描述的范围较概括,capable所描述的范围较专注,因为前者指某人聪明能干,有多才多艺的概括涵义;后者仅指具有应付某一特指工作要求的能力。例: She is an able teacher 她是个能干的教师。 She is a capable teacher. 她是个能胜任工作的教师。 (二)able指“能够”,是一时之现象;capable常用以指“能力”,是经常的现象。如: I shall not be able to come to the office tomorrow. 明天我不能到办公室来(指由于某种原因而暂时不能来)。 She is in capable of manual labour. 她不能从事体力劳动(指由于某种长期或经常的原因,例如患病而不能劳动)。 (三)指某人能作某事时,able之后接动词不定式,capable之后接介词of。例如: We are able to get back to town before dark. 我们能够天黑之前赶回市区。 They are not capable of doing the work. 他们没有能力做这件工作。 (四)capable除表示“有能力的”意味外,还可用以表示“有可能的”涵义,able则没有这个用法。如: The situation is capable of improvement. 此情况有可能好转。 That oil tanker is capable of being restored. 那艘油轮有可能修好。 请注意,下列句中的able是用错了,应改为capable: This book is able to be translated.(错) This book is capable of being translated.(对) That law is able to be evaded.(错) That law is capable of being evaded.(对) (五) able 一般用作正面意义,指好人好事;capable 则是中性词,既可指好事,亦可指坏事,例如在下例中,capable of anything是表示“任何坏事都做得出来”之意: That guy is capable of anything! 那家伙什么勾当都会干得出来! (六) able的反义词是unable;capable的反义词是incapable。另一点值得注意的是,able的名词是 ability,义:“能力”(the power to do);capable的名词是capability 或 capacity,前者义:“具有从事某事的能力”;后者义:“容量”或“受容力”。需要在此指出的是,ability是可以通过练习或锻炼获得的,而capability则是固有的能力,它与练习或锻炼无关。通过下列例句的对比,我们不难区分其义蕴: I do not doubt his ability to do the work. He has the capability to benefit from university education. 第一句的ability是指通过训练或工作磨炼而获得的“能力”;第二句的capability是指天赋之才,与后天无关。2023-07-28 18:22:592

be able to等于什么
be able to=be capable of。当be able to解释为能够做某事的时候,can=be able to;当be able to表示“(过去)成功做”时,be able to=manage(d) to do=succeed(ed) in doing=be successful in doing. be able to翻译 表示“能够做某事”,强调通过努力而获得的能力。 She is able to play the piano. 她能够弹钢琴。 I am able to drive the truck. 我能够开那辆卡车。 She is able to speak three languages. 她能够讲三种语言。2023-07-28 18:23:521
can和be able to用法上的区别
大体上说,纯粹表示主语的“能力”时,can与be able to属同义词,两者可以通用。例如:He can/is able to lift this stone.我能举起这块石头。She could/was able to play the piano when she was five.她5岁时就会弹钢琴了。语义上, can属于情态助动词,它指主语具备某种“潜在能力”,但并不包含该能力的实施;而be able to属于半助动词,它则除了指主语具备某种“能力”外,还往往暗示该能力的付诸实施。据此,在针对现在情况或将来情况时,两者的区别意义不大,常可通用。因为,在现在或将来情况下,主语“潜能”的实施与否未经事后验证。例如:Mr Black can/is able to speak several foreign languages.布莱克先生会讲几门外语。I can/will be able to finish the work before twelve.我会在12点前完成工作的。3. 在针对过去情况时,两者的区别意义明显,不可混用。因为,在过去情况下,主语“潜能”的实施与否,业已成了定局。比较:1)We could save his life.我们有办法救活他。 (但未必实施)2)We were able to save his life.我们得以救活他。 (付诸实施)句1)只表示主语有救人的能力,但未必实施;句2)则表示主语非但有救人的能力,而且业已成功实施了。但在否定句式中,因为表示主语“无能力”,所以不存在能力的实施问题。这时,两者意义统一,可以通用。例如:I couldn"t/wasn"t able to pass the exam.我没能考及格。He couldn"t/wasn"t able to live to see his country reunited.他没能活着亲眼见到祖国的重新统一。4. 居于上述道理,表示主语过去具备某种特定的“能力”时,不能用could,而要用be able to。例如:How much money were you able to earn each month three years ago?3年前,你每月能挣多少钱? (不能用could)2023-07-28 18:24:128

be able to 和can的区别
can 与 be able to 用法比较在一般现在时主动语态中表示“能”、“会”时,两者可互换,意义差别不大.如:I can / am able to reach the apples.但在以下几种情况中两者不能换用:1、在词义上,can 除可以表示“能”、“会”外,还可以表示“许可”、“允许”或可能性,而 be able to 则不可.例句:A :Can it be true?B :No,it can"t be true.2、当表达将来的能力时,一般要用 will be able to; can 一般只有现在时和过去时两种时态形式.用于完成时等其它时态时,也用 be able to.例句:1) I"ll be able to speak English in another few months.2) If I have a good sleep,I"ll be able to work out the problem.3) I"ve not been able to find my bike.但是当人们现在决定将来是否有做某事的能力时,can 也是可以用的.例句:I"m too busy today,but I can help you with your English tomorrow.3、be able to 多表示“人”有能力或技巧做某事,一般不用于指物;而 can 表示人、物的“能”、“会”都可以.例句:This kind of car can run very fast.It"s new.4、can 可以有被动语态形式,而 be able to 则不能用于被动语态.例句:The mistake can"t be corrected.5、can 与 be able to 不能重叠使用.例句:(误)He can be able to do it well.2023-07-28 18:37:372
could和be able to的区别
can,could和be able to的区别can 与be able to在用法上既有相同的一方面, 又有不同的地方,这是应该引起注意的。当它们表示能力的时候,是同义的。如: He can speak two foreign languages. He is able to speak two foreign languages. 它们用法上的不同主要体现在以下几方面: 1. can只有两种时态, 即can 和could, 而be able to 有多种时态, 如was/were able to, will/shall be able to, have/has been able to等: I"ll be able to drive the car in a week. 2.表示过去通过努力终于做成了某事要用be able to,而不能用can。如: I was able to swim to the bank after the boat turned over. can 和be able to 都可以表示能力.can泛指一般的能力,而且只有两种形式,即:can, could.be able to 则主要指具体做到了某件事的能力,其形式主要是靠be 发生变化,所以形式比can 多.可以说:I can swim. I am able to swim. 但是不能说:All the people could escape from the big fire in time. 只能说:All the people were able to escape from the fire in time. 3.can能表猜测,be able to不能。can的这种用法主要用于疑问句和否定句。 Somebody is knocking at the door. Who can it be? It can"t be our teacher who is knocking at the door. 其肯定形式是must be。如: It must be our teacher who is knocking at the door. must have done something 表示对现在完成或过去动作的猜测,其否定形式是can"t have done。如: “His parents must have gone abroad.” “No, I don"t think so. They can"t have gone, for I saw them only this morning.” 要特别注意它们的反意问句形式: He must be a good teacher,mustn"t /isn"t he? The students must have gone to bed, haven"t they? They must have finished their lessons yesterday, didn"t they? could既可以用肯定形式,又可以用疑问或否定形式。如果用could表示现在“可能”,比can语气更加委婉。如: If you don"t spend enough time on your studies, you could fail in the final examination. It could be our teacher who turned off the light last night. 与It must be our teacher. 相比,这句话表示的可能性更小, 因为它表示了两种可能性, 既 “可能是”也可能“不是”,而 must be 只表示了一种猜测。 could have done 这个句型有它的特殊含意,表示“本来可能做到而未做到的事”。如: Our class team could have won the game. 再看以下例句: He cannot be over praised for what he has done for all of us. 他为我们大家做了这些事, 应该受到大大的表扬。 即 “再怎么表扬也不过分”。 4.can 可以表 “允许”, 与may可以互换, 此时不能用be able to 代替。如: “Can / May I sit here?” “Yes, please.” 由于may not 有两个意思, 即 “不可能” 和 “不许可”, 因此使用时要特别注意。如: He may not go home this weekend. 此句既可以表示 He will probably not go home this weekend.也可以表示 I don"t permit him to go home this weekend. 在口语中,表达这两种不同的含义是通过句重音来解决的。如: He may `not go home this weekend. (I don"t permit him to go home this weekend.) He `may not go home this weekend. (He will probably not go home this weekend.) 而在书面表达时不可能使用句重音的手段, 所以最好用can"t代替may not来表示 “不可能”: He can"t go home this weekend. 5. can 是情态动词,只能用作谓语成分,be able to是普通动词短语,既可以作谓语,也可以作非谓语。如: Being able to speak English fluently, he has no difficulty in communicating with the Americans at the party. How I long to be able to communicate with the foreigners in fluent English! 6. be able to 后边接动词不定式表示一种实际情况时,其否定形式不是be not able to,而是cannot。如: Were you able to catch the first bus yesterday morning? No, I couldn"t. 7. 一般说来, be able to 后边的动词不定式没有被动语态。如: I"m sure he is able to correct his mistakes in grammar. 不说: *I"m sure his mistakes are able to be corrected by him.2023-07-28 18:37:442
