◆他能通过考试。
误:He can be able to pass the exam.
正:He can pass the exam. / He is able to pass the exam.
析:be able to 不能与 can 用在同一个谓语中。
◆这工作可按时完成。
误:The work is able to be finished in time.
正:The work is capable of being finished in time.
正:The work can be finished in time.
析:按规范语法:be able to之后一般不接动词的被动式,尽管在 现代英语中已有人打破此规则,但初学者仍以不用为宜。
◆他在公共汽车后面追,并追上了。
误:He ran after the bus, and could catch it.
正:He ran after the bus, and was able to catch it.
析:表示过去特定情况下的能力,可用 was (were) able to 而不 能用 could,不过这种差异在否定句中便不存在了。如:He ran after the bus but wasn’t able to [couldn’t] catch it.
