问题描述：
1."In fact,we used to call each other 'Old Friend'--when we'd meet,that is."
这句话后一句when……that is,是什么结构?‘d是would 还是had?
2.A half hour (went by) before the manager returned to the meeting hall.
为什么不填had gone by?
答
would 因为后面加了动词原形meet
答
"that is”是“就是说”，'d应该是had。
后面有before明确表示时间先后顺序，前面的过去完成时和过去式可以互换的。
答
1.应该是would .如果是had ,后面应该用met ,而不是meet.不是什么特殊的结构,只是语序换了一下.that is 只是起到具体说明 we used to call each other "old friend"的作用.译为“ 实际上,我们过去常叫对方老朋友——那是指在我们能见面的时候.”
答
1、应该是had,
2、went在这里相当于was
