If you must use descendant selectors, prefer child selectors, which at least only require evaluation of one additional node, not all the intermediate nodes up to an ancestor.

如果您必须使用后代选择器，尽量使用子代选择器，这最少只需评估一个额外的节点，而非中间直至祖先的所有节点。

Create a business object layer, called intermediate objects, which serves as a placeholder for data used in event evaluation.

创建业务对象层，即所谓的中间对象，它们将用作事件评估中使用的数据的占位符。

I prefer the term evaluation criteria, which are inherently understood as transient snapshots of objectives for a given intermediate life-cycle checkpoint such as a demonstrable release.

我倾向于使用评估标准这种说法，它被自然理解为目标的瞬间快照，而目标是一个生存周期的中间检查点，比如一个可演示的版本发布。
