    Bikes are made by them.

    注意:
    (1)不及物動詞一般沒有被動語態(tài)。

    易錯的常見的不用被動語態(tài)的不及物動詞有:rise, set, happen, break out, take place, fall, lie, die, etc.
    (2)主動句帶雙賓語(直接賓語和間接賓語)的句子,可將“間接賓語”或“直接賓語”變成被動語態(tài)的主語,還有一個賓語叫保留賓語。一般將“間接賓語”變?yōu)楸粍泳涞闹髡Z。當變直接賓語為被動句的主語時,要在保留賓語(間接賓語)前加一個介詞to(給,表方向)或for(替)。
    My mother gave me a book.
    I was given a book(by my mother).
    A book was given to me(by my mother).
    (3)主動句帶有復合賓語時,變?yōu)楸粍泳鋾r賓語補足語保留在謂語動詞之后,改稱為“主語補足語”即主補。當賓補是不帶to的不定式時,被動句中原省略的to要加上。
    The boss made us work ten hours a day.
    We were made to work ten hours a day(by the boss).
    (4)含有“動-介/動-副/動-副-介”等短語動詞的句子,變成被動語態(tài)時,要把這些短語看成一個整體(相當于一個動詞),不能漏掉任何詞。
    The nurses look after the patients well.
    The patients are looked after well(by the nurses).
    (5)含有“動-名-介”型短語動詞的主動句變?yōu)楸粍泳鋾r,也可將其中的名詞變?yōu)楸粍泳涞闹髡Z。
    He paid much attention to his pronunciation.
    Much attention was paid to his pronunciation(by him).
    His pronunciation was paid much attention to(by him).
    (6)被動語態(tài)與系表結構的區(qū)別:
    被動語態(tài),表“動作”,用相應的時態(tài),時態(tài)變化比較豐富。
    系表結構,表“性質(zhì)”,常用一般時態(tài)。
    The glass was broken by Tom yesterday.
    The glass was broken.
    That book was written by a teacher.
    That book is well written.
