when the project changed over time 被动语态
这句的意思是“项目随时间的改变而变化”,那这里为什么不用 been changed,而是change,project应该是被动的改变啊.

你拿出的句子就是被动的,因为过去分词就有已经完成和被动的意思,加been不算错,但有点累赘了.
再问： Defects are not static, but change over time. 缺陷不是静态的，而是随着时间在变化。 Your perception of your limit can change over time. 你的感知限度会随着时间发生改变。这些不是被动语态，为什么呢
再答：您举的两个例句由非人称名词作主语，所以不用用被动态。但在另外的情况下就可用被动态，例如：If the defects changed over time we would take some other measures（如果缺陷随时间变化，我们将采取其他措施）
