2017英語四級被動語態的構成講解

　　【例句】

　　The first section of New College English is designed for speaking practice and is based on pictures and topics.

　　一般過去時：was/were+given

　　【例句】

　　一般將來時：will/shall be+given

　　【例句】

　　Shall we be asked to attend the opening ceremony?

　　Sir Denis, who is 78, has made it known that much of his collection ____to the nation. (CET-4 1996, 6)

　　A) has left B) is to leave

　　C) leaves D) is to be left

　　本句意思為：78歲的Denis先生聲明他將把他的大多數收藏品留給國家。所以leave應用一般將來時的被動形式。一般將來時可以用來be to do sth表達，因此答案為D.

　　過去將來時：would be+given

　　【例句】

　　The news would be sent to the soldier's mother as soon as it arrived.

　　現在進行時：am/is/are being+given

　　【例句】

　　The machine is being repaired in the workshop. The fifth generation computers, withartificial intelligence, are ____and perfected now. ( CET-4 1996,1)

　　A) developed B) have developed C) are being developed D) will have been developed

　　本句測試點是動詞的時態和語態。develop和perfect是兩個并列的謂語動詞，perfect用的是被動形式，develop也應該用被動形式，而且句子的時間狀語為now，故develop應用現在進行時的被動語態，答案為C。

　　過去進行時：was/were being+given

　　【例句】

　　The feast was being prepared when the birds arrived in the sky

　　現在完成時：has/have been+given

　　【例句】

　　Swift progress has also been made in culture and education.
