Unit3被動(dòng)語態(tài)用法總結(jié)課件英語九年級上冊

被動(dòng)語態(tài)用法總結(jié)被動(dòng)語態(tài)小結(jié)1.考點(diǎn)揭密2.典型例題解析3.課時(shí)訓(xùn)練一、概述

動(dòng)詞的語態(tài)有兩種：主動(dòng)語態(tài)(activevoice)和被動(dòng)語態(tài)(passivevoice)。1.主語是動(dòng)作的執(zhí)行者時(shí)為主動(dòng)語態(tài)；2.主語是動(dòng)作的承受者時(shí)為被動(dòng)語態(tài)。3.在英語中只有及物動(dòng)詞和一些相當(dāng)于及物動(dòng)詞的詞組才有被動(dòng)語態(tài)的形式。主干知識被動(dòng)語態(tài)的構(gòu)成及用法3.被動(dòng)語態(tài)常用于以下幾種情況：①不知道或沒必要說明動(dòng)作的執(zhí)行者；②強(qiáng)調(diào)動(dòng)作的承受者而不是執(zhí)行者；③不愿說出動(dòng)作的執(zhí)行者；④漢語中的“被、受、由”句式常用被動(dòng)語態(tài)。

被動(dòng)語態(tài)的構(gòu)成：

be+及物動(dòng)詞的過去分詞。其中be動(dòng)詞隨人稱、數(shù)和時(shí)態(tài)的變化而變化；被動(dòng)語態(tài)be字變，過去分詞跟后面。isspoken
