　　1)capability和ability区别：

　　ability to do和capability to do区别，在强调某人/物天生具有某种能力用ability好，capability可能强调的是能不能做某事(跟天生没什么关系)，如government&aposcapability或transport system&aposs capability等。

　　1) If we don&apost take great care, SARS could become established in the poorest nations - places like Burundi, Nigera or Malawi - which have neither the high-tech capability of Toronto nor the totalitarian muscle of China to contain it

　　2) capability of sth. to be done表一种属性, 非一种主动的能力。

　　3) capability (of sth.)to do/of doing.

　　sth’s ability可用在无生命主体:

　　Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline’s ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline.

　　2)习惯用法

　　capability to do;GMAT认为capability of X-ing/in X-ing是wordy/awkward的。

　　ability：sb&aposs ability to do sth或ability of sb/sth to do sth

　　capability to do不如ability to do简洁，但不可就此判错。

　　be able to do

　　be capable of doing

　　have ability to do ; ability of sb. to do

　　have capability to do doing ; capability of sb. to do doing

　　以上就是ablility和capability的用法区别，因为有相近之处所以容易被广大考生混淆，希望考生通过本文可以正确区分ablility和capability。更多语法资料尽在澳际留学GMAT考试频道。
