| 释义 | 〔ready〕Available:现成可使用的：〔usable〕That can be used:可使用的，能用的：〔able〕 It should be avoided when such an ascription is unwarranted, as with passive constructions involving forms of the verbbe; thus it is inconsistent to sayThe problem was able to be solved through the method she had learned about in business school, since this sentence ascribes no capacity or ability to the problem itself.In such cases,can or could can usually be substituted: The problem could be solved . . . By contrast, passives withget ascribe a more active role to their subjects, and here theable to construction can be used: 当这种起因并非必要时，则被动态中用到动词be应避免使用这词组， 因此这问题可用她在商业学校中学到的方法来解决 的说法是矛盾的， 其原因是这个句子并未将某种能力归因于问题本身。在这种情况下，通常可使用can 或 could 来替代： 这问题可以被解决… 。相反，带get 的被动态表示一个更为能动的主语， 这样able to 结构就可以用为： 〔arm〕To prepare (a weapon) for use or operation, as by releasing a safety device.打开保险装置：使（武器）处于可使用或操作的状态，如打开保险装置〔durable〕A manufactured product, such as an automobile or a household appliance, that can be used over a relatively long period without being depleted or consumed. Often used in the plural.耐耗品：可使用较长时期而不被耗尽的产品，如汽车或家用电器〔last〕To remain in good or usable condition:耐用：保持良好的或可使用的状态：〔operable〕Being such that use or operation is possible:可操作的：可使用的，可操作的：〔identical〕Some authorities on usage specifywith as the preferred preposition after identical. But eitherwith or to is now acceptable. 一些词语用法上的权威观点认为只有with 才能在 identical 一词后作为介词使用， 但现在with 和 to 均可使用 〔operable〕an operable machine.一台可使用的机器 |
