1、英語動(dòng)詞有兩種語態(tài),即主動(dòng)語態(tài)(the Active Voice)和被動(dòng)語態(tài)(the Passive Voice)。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。如:English is spoken by many people.當(dāng)我們不知道或沒必要提到動(dòng)作的執(zhí)行者是誰或者強(qiáng)調(diào)突出動(dòng)作的承受者時(shí),常用被動(dòng)語態(tài)。(1)一般現(xiàn)在時(shí)的被動(dòng)語態(tài)(2)一般過去時(shí)的被動(dòng)語態(tài)(3)一般將來時(shí)的被動(dòng)語態(tài)(4)一般現(xiàn)在時(shí)帶情態(tài)動(dòng)詞的被動(dòng)語態(tài)考點(diǎn)一 被動(dòng)語態(tài)的構(gòu)成 被動(dòng)語態(tài)由“助動(dòng)詞be+及物動(dòng)詞的過去分詞”構(gòu)成。助動(dòng)詞be 有人稱、數(shù)和時(shí)態(tài)的變化,其變化規(guī)則與be作為連系動(dòng)詞時(shí)完全一樣。被動(dòng)
