現(xiàn)在完成時的被動語態(tài)
一般來說,主動語態(tài)和被動語態(tài)的選用應(yīng)根據(jù)具體的情況而定。下面幾種情況一般用被動語態(tài):
(1)不知道或沒有必要說明動作的執(zhí)行者是誰。
·Such bks have been written fr children.
(2)強調(diào)動作的承受者,而不強調(diào)動作的執(zhí)行者。
·All these prducts have been tested.
一、結(jié)構(gòu)
注:1.主語是行為動作的承受者;
2.動作或狀態(tài)在說話之前已經(jīng)結(jié)束或持續(xù)到現(xiàn)在,并對現(xiàn)在產(chǎn)生影響或造成結(jié)果。
二、基本用法
1.表動作發(fā)生在過去,其結(jié)果對現(xiàn)在產(chǎn)生影響。
(1)Where has the recrder been put?I can’t see it anywhere.
(2)I gt caught in the rain and my suit has been ruined.
2.表動作從過去開始,一直持續(xù)到現(xiàn)在,可能還會延續(xù)下去。常與時間狀語recently、lately、in/during/ver the past/last few years、s far、up t/till nw、by nw、since、ever since+時間點,fr+時間段等連用。
(1)The machine has been repaired fr tw hurs.
(2)His wrk hasn’t been finished s far.
3.用在時間或條件狀語從句中,表示將來某時已完成的動作,即用現(xiàn)在完成時的被動語態(tài)代替將來完成時的被動語態(tài)。
When the bk has been published this year,the number f bks he has written will reach thirty.
