一.構(gòu)成：英語動(dòng)詞有主動(dòng)和被動(dòng)兩種語態(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。? be+done（動(dòng)詞的過去分詞）
例句：He wrote the letter.? ? ?
變成被動(dòng)語態(tài)：The letter was wrotten by him.
be done 中的be動(dòng)詞體現(xiàn)了時(shí)態(tài)、人稱、數(shù)的變化，同時(shí)也是助動(dòng)詞。
1.下面用“我被告訴”舉例
2.疑問句：那兒說英語嗎？
英：Is English spoken there?
3.否定式：那兒不說英語。
英：English is not spoken there.
4.帶有情態(tài)動(dòng)詞的被動(dòng)語態(tài)：情態(tài)動(dòng)詞+be+done
例句：這事一定要做。
英：It must be done.
5.帶有不定式的被動(dòng)語態(tài)：to be done
例句：下一步該干什么？
英：What is to be done? next?
二.主動(dòng)語態(tài)變被動(dòng)語態(tài)
注意兩點(diǎn)：1.主動(dòng)變被動(dòng)時(shí)，謂語動(dòng)詞的人稱和數(shù)要與被動(dòng)結(jié)構(gòu)的主語保持一致
2.變被動(dòng)語態(tài)，時(shí)態(tài)要保持一致
例句1.? I usually borrow books from the library.
變被動(dòng)：The boos are usually borrowed by me from library.(一般現(xiàn)在時(shí))
例句2：Each of us told a story at the party.
變被動(dòng)：A story was told by each of us at the party.(一般過去時(shí))

例句9：We can finish the project within 10 days.
變被動(dòng)：The project can be finished by us within 10 days.(帶情態(tài)動(dòng)詞變被動(dòng))
注意：省to的動(dòng)詞不定式用于被動(dòng)語態(tài)要還原to
例句1：The teacher made the students do the homework.
變被動(dòng)：The students were made to do homework by the teacher.
