efficient的详细讲解:

词语用法

  1. efficient修饰人、事物、行为皆可,是“能胜任的”、“得力的”或“有效率的”的意思。

    He's not very efficient:he works very slowly.
    他不是很有效率,做的很慢。

  2. efficient与effective,effectual和efficacious都不同:effective是“很有效的”意思,用于事物或人,一般是呈现出正确的结果或是解决了问题。effectual是“达到目的的”意思,不能用于人。efficacious是“必然有效的”意思,程度比effective轻,尤指药品。efficient是“有效率的”,可以用于人,事物和行为。
