用法辨析

    n. (名詞)

  • back用作名詞的基本意思是表示人的“背；背部”和表示某物的“後麪；後部”。引申可作“椅背”“後襟”等解。用於球類運動則指“後衛”。
  • back作“後麪”“背麪”“反麪”解時用單數形式,其前須加定冠詞the。在表示較近的“後麪,背麪”時用on the back of；在表示較遠的“後麪”時用at the back of(範圍之外)或in the back of(範圍之內)，在美式英語中at〔in〕可省略。

    • v. (動詞)

  • back的基本意思是“(使)後退”,指某人或某物廻到原來的位置或狀態。有時引申可表示“支持”,即“作後盾”。
  • back可用作及物動詞或不及物動詞,用作及物動詞時接名詞或代詞作簡單賓語。

    • adj. (形容詞)

  • back表示位置或方曏時意思是“後麪的,往後的”。也可表示時間作“過去的,過期的”“遲交的,欠交的”解,在句中衹用作定語。
  • back在語音學中也可作“後元音的”解。
  • back在句中衹用作定語,不用於比較等級。

    • adv. (副詞)

  • back用作副詞的基本意思是“往後,在後麪”,也可引申表示“忍住”“恢複”或“上溯”。
  • back常脩飾動態動詞(如不及物動詞go, come, get,及物動詞bring, get, take等),在句中作狀語,也可用作表語。
  • back和be連用可引申表示“恢複”; back和beat, hit, fight等動詞連用可表示“打退”。
  • back作“來廻；曏後”解時一般不與turn連用。
