如：They asked a question. 他们问了一个问题。
这里的asked是过去式，构成一般过去时。
1. I have asked her three times, but she hasn't replied yet. 我已经问了她三次，但她还没有回复。
2. By the time the teacher arrived, the students had already asked each other all the questions. 在老师到达之前，学生们已经把问题都互相问完了。
3. By next month, I will have asked everyone in the department for their feedback. 到下个月，我将已经询问过部门里的每一个人以获取他们的反馈。
4. She said she would have asked him to join us, if she had seen him yesterday. 她说，如果她昨天见到他了，她就会已经邀请他加入我们了。
注：还有6种时态的被动语态只是理论上存在，但实际上极少使用，这里不再列举。
例：
1. The chef prepared a dish inspired by traditional recipes. 这位厨师准备了一道受传统菜谱启发而制作的菜肴。
prepared是过去式，是谓语动词；inspired是过去分词，作后置定语修饰“dish”。
2. Exhausted by the long journey, she decided to rest immediately. 由于长途跋涉而精疲力尽，她决定立刻休息。
Exhausted是过去分词，作原因状语；decided是过去式，是谓语动词。
