able的用法：

7. The construction able to ascribes to its subject the ability to accomplish the action expressed in its complement:
词组able to 表示其主语具备完成补充成分里所提到的行为的能力：

The troupe was able to get a grant for the project from a large corporation.
军队可以从一个大公司里获得这个项目的赞助。

The new submarine is able to dive twice as fast as the older model.
这种新潜艇可以比旧型号快一倍。

8. It should be avoided when such an ascription is unwarranted, as with passive constructions involving forms of the verb be; thus it is inconsistent to say The 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 with get ascribe a more active role to their subjects, and here the able 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：

He was able to get himself accepted by a top law school.
他可以使自己被一所一流法律学校所录取。
