had done 是过去完成时,have done是现在完成时,那have been和had been呢?be不是动词呀 现在完成时 过去完成时 怎样强调动词 是have/had done+动词原型吗 请问,现在完成时比如说have kept 和have been done.那如果是have eaten中间为什么不加be have had . 和have done . had done . 和 have been doing . had b have done.have been done .had done.had been done 有什么区别?怎么用?有 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? 现在完成时和过去完成时一般的意思是什么 have done和had done的意思 have been done 和 to be done 请问have\has\had done和have\has\had been done 各有什么区别?been和gone又 have done是现在完成时 have been done 是不是现在完成时的被动吖 英语时态区分have done .have been doing.had done.had been doing.有什么 have been doing 和have done 还有had done三者的区别,用法
