查询词典 backward

TO eliminate error caused by the rod being tipped forward or backward, the rodman waves the rod ,or tilts it slowly forward and backward,and the leveler takes the least reading. For less precise leveling, as when rod rcadings for ground points are determined to the nearest 0.1 ft, usually less care is exercised in keeping the bubble centered and the rod vertical,and the observations are no checked.

等到《爵士音乐世界史》演奏完毕，有的姑娘像小哈巴狗一样乐滋滋地靠在男人肩膀上，有的姑娘开玩笑地向后晕倒在男人怀抱里，甚至倒进人群里，明知反正有人会把她们托住——可是没有人晕倒在盖茨比身上，也没有法国式的短发碰到盖茨比的肩头，也没有人组织四人合唱团来拉盖茨比加入。
