动词+~ ~+名词 副词+~ ~+动词不定式 ~+介词


  • The Hands are the most habil members of the body.

    出自:T. Betterton
  • And life, by this death abled, shall controule Death.




  1. able常以be able + 不定式的形式出现,与can 同义。有些具体情况下只能用 be able,而不能用 can。

    Some people are able to/can walk on their hands.

    One day,scientists will be able to find a cure for cancer.
    (NOT...will can find...)

  2. 后面的不定式通常不属于被动语态。

    The mistake is able to be corrected.
    该句应改作The mistake is capable of being corrected.

  3. 指能力时,不一定意味着实行,如“经过了两个月的步行,他们到达了目的地”通常不说 After a two-month tramp, they were able to reach their destination.而是用 After a two-month tramp they reached their destination。
  1. 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。
  2. 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。
  3. 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。
  4. 除be外, able还可用在其他系动词如seem, feel等之后。
  5. able作“聪明的,能干的”解时可受副词very, quite, more, better, poorly等修饰。
  6. able作“能够…的”解时比较级和最高级可用abler/ablest,也可用more able/most able。作“聪明的,能干的”解时比较级和最高级用abler/ablest。
  7. 有人认为be able to do sth中的to do sth是形容词able的补语,不过更多的是把be able to看作是一个起助动词作用的短语。


able, capable
1.able常指做某事所需要的力量、技巧、知识、才干等,一般与效率无关,含有“精明能干,超过一般水平”的意思; capable指满足一般要求的能力,可以是表现出来的,也可以是潜在的。故可以说able表示的能力要比capable高。试比较下面两句:
  • He is a capable lawyer.
  • 他是位能干的律师。
  • He is an able lawyer.
  • 他是位颇有才干的律师。
  • He's an able man who you can fall back on.
  • 他是个能干的人,你可以依靠他。
  • The scandal is capable of the basest tricks.
  • 这个坏蛋什么卑鄙的勾当都干得出来。
3.able一般用于有生命的人或动物,即使是用于指一件做得很成功的事,其含义也重在表示做成该事的人有才能; 而capable则可用于无生命的事物。试比较下面两句:
  • The doctor performs a very able operation.
  • 那大夫做了一个很成功的手术。
  • Glass, which breaks at a blow, is, nevertheless, cap- able of withstanding great pressure.
  • 玻璃尽管一击就碎,却能承受很大的压力。
4.用作表语时, able后接动词不定式; capable后接“of+名词或动名词”。试比较下面两句:
  • He is able to look after〔capable of looking after〕 him- self now.
  • 现在他自己能照顾自己了。
  • He is capable of hard work.
  • 他能胜任艰苦的工作。
  • She is not able to dance tonight.她今晚不能跳舞。
  • The lame girl is not capable of learning to dance.
  • 这个跛脚的姑娘学不了舞蹈。
  • He is able to overcome all kinds of difficulties.
  • 他能克服各种困难。
  • This car is capable of carrying five persons.
  • 这辆轿车可载客5人。
able, enable
这两个词都可接动词不定式。其区别在于: to- v 的意思是“能够”; 而enable to- v 的意思是“使能够”。
2.able是形容词; 而enable是动词,其后须接宾语。
be able to, can
Can I come in?我可以进来吗?
That can't be true.那不可能是真的。
以上两句都不可换用be able to。
2.can只有现在时和过去时两种形式,而be able to则有多种时态形式。试比较下面两句:
  • Will you be able to come tomorrow?
  • 你明天能来吗?(将来时)
  • This factory has been able to produce newly-devised sewing machines.
  • 这家工厂已能生产新设计的缝纫机了。(完成时)
3.在be able to之前可加用另外一个助动词,且多用于否定或疑问结构,而can则无此用法。
4.用于否定结构, be able to表达一时情况,而can则表达往常情况。试比较下面两句:
  • He is not able to swim today.
  • 他今天不能游泳。
  • He can't swim at all.
  • 他根本不会游泳。 able to后可接系表结构,表示一种状态或性质;而can没有这种用法。例如:
He was able to be cold about her now.他现在对她可能有些冷淡。 able to有非谓语动词形式,而can则没有。例如:
I hope to be able to do the work.我希望能做这项工作。
was/were able to, could
1.was/were able to只能表示一次性事件,不能表示经常性事件; 而could可以用来表示习惯性动作的完成。例如:
I could run after a bus and catch it twenty years ago, but I can't do that now.20年前我能追上公共汽车,现在不行了。
2.was/were able to不仅表示过去的能力与可能性,还表示“能够并确实做到”,相当于managed to do,而且重点往往在于“成功地实行”; 而could主要表示“潜在的能力”。例如:
  • I was able to pass the examination.
  • 我成功地通过了考试。
  • I could pass the examination.
  • 我曾有能力通过考试。
  • 但在否定句中,这种“潜能”与“完成”的区别就不存在了。两者都可以表示动作的未完成。例如:
  • I ran after the bus, but couldn't〔wasn't able to〕 catch it.我跑着追那辆公共汽车,但没能追上。
able capable competent
  • able:able最常用词,多用于褒义,着重指多方面的,经常性的,或潜在性的能力。有时也指高超、非凡的能力。
  • capable:capable语气弱于able,指有能力、有潜力或有条件做某事,常与of连用。
  • competent:competent强调具有能胜任某项工作的足够技能或其它所需的条件。


  1. 经过两个月的步行,他们到达了目的地。

    After a two-month tramp they were able to reach their destination.

    After a two-month tramp they reached their destination.

    After a two-month tramp they succeeded in reaching their destination.

    After a two-month tramp they managed to reach their destination.


  2. 这工作无法在一周内完成。

    This work wasn't able to be finished in a week.

    This work can't be finished in a week.

  3. 星期天可以见你。

    It will be able to see you on Sunday.

    It will be possible to see you on Sunday.

  4. 星期日我能见你。

    I'll be possible to see you on Sunday.

    I'll be able to see you on Sunday.

    非生物名词作主语时用can或be possible to;“人”作主语时才用be able to。

  • 错句:he told the commons his objective was to ensure that the ceasefire was able to be turned into a permanent peace.

    纠正:he told the commons his objective was to ensure that the ceasefire could be turned into a permanent peace.




  • ☆ 14世纪中期入英进语,直接源自古法语的(h)able;最初源自拉丁语的habilis,意为便利的,适合保持的。
