单词 able
释义
able/′eɪbl/ adj [-r/-st,more/most~]

(1)能,会(having enough strengthknowledge or the meanstimeopportunityetc needed to do sth) [A+to-inf][作pred](be able to =can):be~to write music/to speak French/to do the quizzes 会作曲/说法语/答这些竞赛题;be~to drive/to lift the box/to work part-time 能开车/搬起这盒子/做兼职工作;You are better/more~to do it than him.你比他更有能力做这件事。I thought I wouldn't be~to visit you this week.我原以为本周我不能来拜访你。He will come if he is~.他要是能来,他会来的。〖同〗capable;〖反〗unable,incapable;

(2)能干的,有能力(本事)的(clever and skilful):an extremely(unusually)~lawyer/detective/nurse 极(很)有才干的律师/侦探/护士;the~st/most~student in the class 班上能力最强的学生;He's the most~of our pupils.他是我们的学生中能力最强的。an~r actor than people thought比人们想象的还要有才能的演员;He is still quite~.他仍然很能干。an~speech/performance 精彩的演讲/表演;put forward an~defence of one's client为委托人进行有力的辩护;〖同〗skilful,capable,expert;〖反〗unskilful,incapable,inexpert;

→′ably adv 能干地;un′able adj不能(会)的;͵able-′bodied adj 健壮的;a′bility n;

【用法】因can仅有can,could 两种形式,而be able to 中的be则可有多种变化形式,故able 常用于须表示“能、会”而不能用can的情况。但注意:be able to 后不可用动词的被动式。

【辨异】ablecapable基本同义。able语义更强,指与所需努力相当的充分能力;capable语义较弱,指满足一般需要的能力,常可指干坏事,或表示有某种可能性,接of+ing 分词(或名词),如:be capable of better work/murder(能把工作干得更好/有可能进行谋杀)。还有competent,指胜任某工作的能力,既可接不定式,也可接for+ing 分词(或名词),如:be competent to look after children(能胜任照看小孩)。
