[誤] Their eyesight met, and they fell in love with each other ever since.
[正] Their eyes met, and they fell in love with each other ever since.
注:“目光”不能用 eyesight 表達,因為 eyesight 只能指“視力”,如:If you eat a lot of fish, you can have good eyesight(多吃魚會使你的視力好)。而 eye 不僅表示“視力”,還可以指“眼光”。如:a good eye for distance(能看很遠的好視力)和 She met his eye across the room(隔著房間,她與他的目光相遇了)。
