語法精析
現在完成時的被動語態表示到現在為止某事已經被完成或被做。這種語法項目既要表示現在已經完成又要表示被動的含義，因此很多同學在具體運用中容易顧此失彼，難以把握。
運用現在完成時的被動語態時應掌握以下幾個問題：
一、現在完成時的被動語態的常用句式
肯定式 主語＋have/has been done...
否定式 主語＋have/has not been done...
一般疑問式 Have/Has＋主語＋been done...？
特殊疑問式 疑問詞＋have/has＋主語＋been done...？
He has been admitted to the club.
他已被接納為俱樂部成員了。
Tom’s novel has not been published.
湯姆的小說還沒有被出版。
Has his bike been repaired?
他的自行車修好了嗎？
Who has been invited?
誰受到了邀請？
二、現在完成時的被動語態的用法
1.表示被動的動作在說話之前已經完成，強調過去的動作對現在造成的影響或產生的結果，通常與already，yet，never，recently等副詞及時間狀語so far，by now，up till/to now，since等連用。
The room has already been cleaned.
這個房間已經被打掃干凈了。(現在已經不用打掃房間了)
2.表示一個被動的動作或狀態從過去開始一直持續到現在，并可能繼續持續下去，常與for或since等引出的時間狀語(從句)連用，或用于how long引出的句子中。
The machine has been repaired for two hours.
這臺機器已經被修了兩個小時了。(可能還會繼續被修)
3.用在條件狀語從句中，表示將來某時已經完成的動作。
You shouldn’t leave school before your homework has been finished.
在你的作業沒完成之前你不應該離開學校。
三、使用現在完成時的被動語態要注意6點問題
1.與一般過去時的被動語態的區別。一般過去時的被動語態所表示的動作或狀態與現在的情況沒有聯系，而現在完成時的被動語態則強調與現在的情況有聯系。
The park was opened to the public last year.
去年這個公園向公眾開放。(說明動作發生于過去)
The park has been opened to the public.
這個公園已向公眾開放。(說明動作發生于過去，但對現在有影響，即現在公園已經向公眾開放了)
2.非延續性動詞，如borrow，finish，begin，start，buy，marry，open，join等構成的現在完成時的被動語態不能與表示一段時間的狀語連用。若要表達相應的意思，則要改換動詞或時態。
The work was finished two weeks ago.這項工作于兩周前被完成。
The work has been finished.這項工作已經被完成。
3.短語動詞是一個不可分割的整體，在被動語態中要保持完整性，其中的介詞或副詞不可省略。
It is said that the problem has been looked into.據說已經調查了這個問題。
