It takes/took/be+時間段+before… “多久之后才…”

三、語法----被動語態(tài)
(一)概念：主動語態(tài)表示主語是動作的執(zhí)行者，被動語態(tài)表示主語是動作的承受者。
(二)各種時態(tài)被動語態(tài)的形式
1.一般現(xiàn)在時的被動語態(tài) am/is/are + done
2.一般過去時的被動語態(tài) was/were + done
3.一般將來時的被動語態(tài)⑴will/shall be done⑵be going to be done⑶be to be done
4.現(xiàn)在進行時的被動語態(tài) is/am/are + being +done
表示說話人說話時或現(xiàn)階段正在進行的動作，經(jīng)常和時間副詞now (現(xiàn)在), right now (現(xiàn)在,此刻), at present (現(xiàn)在,目前), at this moment (此刻)連用。
5.現(xiàn)在完成時的被動 have/has been done
現(xiàn)在完成時常與already,always, often, ever, never, yet, not...yet, just等不表示明確的時間副詞連用,還可以和表示時間一直延續(xù)到目前的帶(ever )since, for的狀語及包括現(xiàn)在在內(nèi)的詞連用。如: now, today, thismonth, this year, recently, these days，many times, so far, by now, in the past/last few days/years…等。
6.過去完成時的被動 had been done
7.過去將來時的被動 would be done
8.過去進行時的被動 was/were being done
9.帶情態(tài)動詞的被動語態(tài)情態(tài)動詞 + be done
10.動詞不定式的被動式 to be done e.g. It is an honor for me to be asked tospeak here.
(三)注意事項：
1.并不是所有動詞都有被動語態(tài)
happen,take place, break out, belong to, cost, last等不及物動詞或詞組無被動語態(tài)。
2.短語動詞、固定搭配變被動語態(tài)介詞副詞不省。
E.g. Time should be madefull use of.
3.雙賓語：一個賓語成主語，另一主語保留不變。
E.g. Mother will buy me an iphone5.
→ I will be bought an iphone5 (by mymother) .
→ An iphone5 will be bought for me(by my mother) .
4.復(fù)合賓語(含賓補)省to動詞不定式變被動還原to
使役：make sb. do sth.→Sb. be made to do sth.
感官類：see/hear sb. do sth.→Sb. be seen/heard to do sth.
e.g.Mum made me clean the floor.
→I was made to clean the floor.
