ThepassivevoiceofthesimplepresenttensePresentation被動(dòng)語態(tài)(一)概念：英語中動(dòng)詞有兩種語態(tài)：主動(dòng)語態(tài)和被動(dòng)語態(tài)。主動(dòng)語態(tài)表示主語是動(dòng)作的執(zhí)行者，被動(dòng)語態(tài)表示主語是動(dòng)作的承受者。e.g.PeoplegrowteainHangzhou.Teaisgrown(bypeople)inHangzhou.

(二)構(gòu)成：被動(dòng)語態(tài)由“be＋及物動(dòng)詞的過去分詞”構(gòu)成，其中be有人稱、數(shù)和時(shí)態(tài)的變化。e.g.Iamoftenaskedthequestionsbymypupils.
