过去将来完成进行时，由should/would have been v-ing构成；否定形式should/would not have been v-ing，I heard by July you’d have been teaching here for ten years. 　　我听说到七月份，你就在这里教了10年书了。 He said that by the end of the spring term he would have been studying English for three years. 　　他说到了春季学期末，他就学了三年英语了。 I knew by that time he would have been working there for 30 years. 　　我知道到那时他他就在那儿工作满30年了。 She told me she’d have been teaching in that university for 20 years by that summer. 　　她告诉我到那年夏天她在那所大学教书就满20年了。
