Has / Have + been +過去分詞???

Q1:)
Has / Have been 過去分詞
與
Has / Have 過去分詞

有咩分別?

咩時候先要加been呢? 咩時候唔需要?

分別在於 been 時係被動語態, 唔 been 就係現在完成式你要用被動語態時咪要 been 囉, 至於詳情點用, 可到我之前回答的問題看:http://hk.knowledge.yahoo.com/question/question?qid=7007062002963


Q2:)
被動句裡.
係唔係一定要加be ? (意即被打.被印.被關了等等...?)

無錯, 但要注意時式, 如果係現在式要用 is/am/are過去式用was/were, 現在完成式用 has been/ have been過去完成式用 had been, 將來式用 will be將來完成式用 will have been 等等...詳情可到以上網址睇
