had looked这类短语是过去完成时么? It had been many years since my wife and I had gone dancing it + 过去完成时 + since + 例句：it + 过去完成时 + since + 过去完成时为什么不是it + 过去完成时 + since + 过去式?真的是it + 过去完成时 + since + 过去 had been broken ,had broken 哪个是过去完成时呢 怎么区分 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? I've already had lunch过去完成时,这句短语中请问怎么运用理解啊?其中have or had 第一句中为什么要加have 是因为有already在才多一个have吗?had lunch就是吃过午饭的意思.为什么要多加个have?I had already 过去完成时的构成过去完成时是由“had +动词的过去分词”构成,但是为什么说had通常用于任何人称?had到底怎么变化? 怎样区分过去完成时和现在完成时过去完成时是had+V现在完成时是have has +V但什么时候用过去完成时什么时候用现在完成时 The doctor looked over him carefully after he to the hospital.The doctor looked over him carefully after he to the hospital.空格处我知道填写 was taken 但是为什么不用 过去完成时 填 had been taken 间接引语改直接引语什么时候把一般过去时改为一般现在时什么时候改为现在完成时不是现在完成时，而是过去完成时。如：Had xxed这类的时态。 car__and we had to walk home.怎么填?这是一道 适当形式填空题 提供的短语是 break down 还有,我是这样填的——The car has been broken down and we had to walk home.就是过去完成时的,这样可以吗?还有一种填法— 过去完成时的标志词,标志短语是什么? 高中英语出现什么短语用现在完成时、过去完成时? a large crowd of people had gathered under the Town Hall是过去完成时 改为过去式 英语中过去完成时是have还是had?它是怎样构成的?还有哪些时态?请举例! i had called you last monday!这里用过去完成时,是过去的时间词没错吧 we cleaned up as soon as guests had 后面是过去完成时 after he had corrected them请问这句话是过去完成时吗?
