The Hands are the most habil members of the body.出自：T. Betterton
And life, by this death abled, shall controule Death.出自：Donne
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...)
The mistake is able to be corrected.
该句应改作The mistake is capable of being corrected.
- 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。
- 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。
- 除be外, able还可用在其他系动词如seem, feel等之后。
- able作“聪明的,能干的”解时可受副词very, quite, more, better, poorly等修饰。
- 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。
- 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
- He is a capable lawyer.
- He is an able lawyer.
- He's an able man who you can fall back on.
- The scandal is capable of the basest tricks.
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:
- The doctor performs a very able operation.
- Glass, which breaks at a blow, is, nevertheless, cap- able of withstanding great pressure.
- He is able to look after〔capable of looking after〕 him- self now.
- He is capable of hard work.
- She is not able to dance tonight.她今晚不能跳舞。
- The lame girl is not capable of learning to dance.
- He is able to overcome all kinds of difficulties.
- This car is capable of carrying five persons.
- able, enable
这两个词都可接动词不定式。其区别在于:1.able 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
这两者都有“能”的意思。其区别在于:1.can还可表示“可以”“可能”,即具有某种感情色彩。例如: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:
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:
- Will you be able to come tomorrow?
- This factory has been able to produce newly-devised sewing machines.
5.be 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。6.be 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。
- He is not able to swim today.
- He can't swim at all.
- was/were able to, could
这两者的共同意思是“过去能够”。其区别在于: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.
- I could pass the examination.
- 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。
误 After a two-month tramp they were able to reach their destination.
正 After a two-month tramp they reached their destination.

误 This work wasn't able to be finished in a week.
正 This work can't be finished in a week.
误 It will be able to see you on Sunday.
正 It will be possible to see you on Sunday.
误 I'll be possible to see you on Sunday.
正 I'll be able to see you on Sunday.
析 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.
