一、被動語態(tài)1.英語動詞有兩種語態(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，被動語態(tài)表示主語是動作的承受者。
②我們都被那個故事感動哭了。We ___________ t tears by the stry.我們沒有被那個故事感動哭。We _______________ t tears by the stry.你們被那個故事感動哭了嗎?Were yu _______ t tears by the stry?
were nt mved
2.主動變被動解題步驟:
1. 找賓語 ——即動作的承受者
2. 判斷賓語的單復數——即be動詞的單復數
3. 判斷動詞的時態(tài) ——即be動詞的時態(tài)
4. 修改謂語的時態(tài)——即原句動詞改為過去分詞
5. 修改原句的主語——即by+ 主語 / 賓語
3.主動語態(tài)變被動之歌：被動語態(tài)強調賓，be后加上過去分。be要隨著主語變，人稱時態(tài)要弄準。行為對象作主語，邏輯主語by來引。
