He had worked for us for 10 years是过去完成时吧?
这句话和He used to work for us for 10 years有区别吗?两者应该都是过去完成时吧,我在语法书上看到过去完成时是had+过去分词,但是后面这句话里面并没有had阿

1 He used to work for us for 10 years-------这是一般过去时,但应该去掉for 10 years.
2 He worked for us for 10 years -------这句子比 1 好.-------表明他以前在这里工作过,与现在无关.
3 He had worked for us for 10 years BEFORE he left for another company.------通常要有一个时间状语来修饰主句,否则“过去完成时”就不能用,只能是 2.

He had worked for us for 10 years是过去完成时吧? I HAD WORKED HERE FOR 3 YEARS He worked here for eight years! had been married for 50 years 那意思不是现在完成时吗?怎么（had）是过去完成时? He told us that he had worked here since 10years before.这个句子 He;s worked in this factory for many years He has worked here for over three years. He worked in that school for 8 years. My grandfather r---- after he worked for over 30 years Kat worked in administration for many years Kat had worked i He worked here for ten years.(对 for ten years提问） He worked on it for five years.对for five years提问
