译文 说句公道话，必须认识到高跟鞋有值得肯定的一面。
点睛 本句的主干是...it must be noted that...。其中，that引导的主语从句是形式主语it指代的真正主语；for the sake of fairness为目的状语。
for the sake of意为“为了……的利益或好处”。fairness意为“公平，公正”。

positive意为“积极的”。如：

此外，它还可以表示“肯定的；绝对的”。如：

passive意为“消极的”，相当于negative。此外，它还可以表示“被动的”。如：

optimistic意为“乐观的”。如：
The President says she is optimistic that an agreement can be worked out soon. 总统说，她相信不久就会达成共识。
pessimistic意为“悲观的”。如：
