殺死敵人盟友slay-slain-slain思考：什么時候用被動語態(tài)?

語態(tài)用來表示主語與謂語之間的關(guān)系，它是動詞的一種形式。英語中有兩種語態(tài)：主動語態(tài)和被動語態(tài)。主動語態(tài)表示主語是動作的執(zhí)行者，而被動語態(tài)表示主語是動作的承受者。不知道動作的執(zhí)行者沒有必要指出動作的執(zhí)行者強調(diào)動作的承受者Presentperfectpassivevoice思考：現(xiàn)在完成時的被動語態(tài)有什么意義？Presentperfectpassivevoice主語和謂語是被動的關(guān)系：

表示動作從過去一直持續(xù)到現(xiàn)在，有可能還會繼續(xù)進行

動作已經(jīng)完成，強調(diào)對現(xiàn)在造成的影響或結(jié)果例句現(xiàn)在完成時被動語態(tài)句式Theresearchhasbeendonesuccessfully.Theauthor’snewstoryhasnotbeenpublished.Has
