1.We ought to set clear rules of the road that promote transparency and accountability.

ought to和should区别

(1)一般说来，两者可替换，只是ought to语气稍重。如：

You ought to [should] go and see Mary sometime. 你应该什么时候去看看玛丽。

The train ought to [should] have arrived at six. 火车本应该6点钟到的。　

(2)表示出于法令规则、行为准则、道德责任等客观情况而“应该”做某事时，一般应用ought to，若用should则含有个人意见，强调主观看法。如(from www.nmet168.com)：

We ought to go and see Mary tomorrow, but I don’t think we will. 明天我们按理应该去看看玛丽，但是我认为我们不会去(此句不宜用should)。

(3)在公告、须知或条例中，出于礼貌，常用should。如：
You should not run alongside the swimming-pool. 不准在游泳池边奔跑。
