back and forth中等

Madrid’s back and forth on clean air is a pointed reminder of the limits to the patchwork, city-by-city approach that characterises efforts on air pollution across Europe, Britain very much included.

马德里在清洁空气问题上的反复，尖锐地提醒人们：整个欧洲（英国也绝不例外）治理空气污染所特有的那种拼凑式、各城市各自为政的做法存在局限。

Carnegie would be right if arguments were fights, which is how we often think of them. Like physical fights, verbal fights can leave both sides bloodied. Even when you win, you end up no better off. Your prospects would be almost as dismal if arguments were even just competitions — like, say, tennis games. Pairs of opponents hit the ball back and forth until one winner emerges from all who entered. Everybody else loses. This kind of thinking is why so many people try to avoid arguments, especially about politics and religion.

如果争论就是争斗——我们常常这样看待争论——那么卡耐基就是对的。和肢体冲突一样，口头争斗也会让双方都头破血流。即使你赢了，最终也不会更好。即便争论只是竞赛——比如说网球比赛——你的前景也几乎同样黯淡。对手们两两对阵，来回击球，直到所有参赛者中产生一个胜者。其他人都是输家。正是这种想法让那么多人尽量避免争论，尤其是关于政治和宗教的争论。
