The reserve [singular] / the reserves [plural] (BrE, NAmE) is an extra military or police force that is not part of a country's regular forces, but is available to be used when needed. 尤其在英式英语中，复数形式的the reserves指替补运动队。单数形式的the reserve或复数形式的the reserves指预备役部队、后备警察队◆The missile landed on a US army reserve barracks.导弹落在一处美国预备役部队军营。 ■ surrogate ˈsʌrəgət; NAmE ˈsɜːrəgət [countable] (often used as an adjective 常用作形容词) (rather formal) a person or thing that takes the place of, or is used instead of, sb/sth else 替代者；替代物；代用品◆She saw him as a sort of surrogate father.在她心目中，他仿佛是能替代父亲角色的人。◆For these people, television is a surrogate for real life.对这些人来说，电视是现实生活的替代品。ⓘ In everyday English, surrogate is most often used to talk about people who take the place of real parents.
