被動語態文法句型
主詞（動作的承受者）＋be動詞＋過去分詞pp＋（by +動作的施予者）不能做出該動作的主詞就要使用被動，如食物被吃、衣服被穿、照片被拍…..
被動的基本結構是 be動詞+PP
(be動詞是助動詞， 主要動詞的詞彙意義在「過去分詞pp」。)
被動語態的BE動詞決定時態
不一定都有「by ….」片語。動作的產生者為people、you、we、they、someone等不特定對象時，「by ….」片語可省略。
被動語態時態表
| 時態 | 變化 | 例句 |
| 現在簡單式的被動 | is / am / are＋p.p. | The cake is eaten by me. 蛋糕被我吃 |
| 過去簡單式的被動 | was / were＋p.p. | The cake was eaten by me. |
| 未來簡單式的被動 | will be＋p.p. | The cake will be eaten by me. |
| 現在進行式的被動 | is / am / are＋being＋p.p. | The cake is being eaten by me. |

被動語態疑問句
1. be動詞為首的問句→依一般Yes-No句型變化之。
直述句：Most of the websites are built in English.
疑問句：Are most of the websites built in English?
回答：Yes, they are.
2. 疑問詞為首的問句→依一般疑問詞句型變化之【疑問詞＋be動詞＋主詞…..】。
疑問句：When was the book put on the desk by John? 答：Yesterday.
Where was the book put by John yesterday? 答：On the desk.
What was put on the desk by John yesterday? 答：The book.
By whom was the book put on the desk yesterday? 答：John.
說明：詢問被動動作的產生者（John）時，須以「介係詞＋whom/ what」為首來發問。
The book was written by a famous artist.=By whom was the book written?
The bugs have been killed by the modern machine.=By what have the bugs been killed?
使役動詞被動語態
主動句型：主詞+使役動詞＋受詞＋原形動詞.
被動句型：主詞＋be動詞＋使役動詞過去分詞＋to＋原形動詞＋by＋受詞.
A be made/had to VR by sb. (A被要求做某事)
主動：My mother made me do the housework yesterday. (我媽媽昨天命令我做家事。)
被動：I was made to do the housework yesterday by my mother .(我昨天被媽媽命令做家事)
主動語態使役動詞句中的受詞，原本使用 「原型動詞」，為特殊動詞用法。但改成被動語態後，因主要動詞為be動詞，p.p.(使役動詞)失去原本的使役特性，需視為一般動詞的過去分詞。故不可以在句中出現第二個動詞。故主動語態的「原形動詞」需改為「不定詞」，並置於被動句中的過去分詞之後。
主動：Cindy has us hand in the report right away. (Cindy要求我們立刻繳交報告。)
被動：We are had to hand in the report right away by Cindy. (我們被Cindy要求立刻繳交報告)
主動：Mom made Susan wash the dishes this evening. 媽媽今天晚上命令蘇珊洗碗
被動：Susan was made to wash the dishes this evening.
let在被動語態中，不被使用。要改成此字allow（允許）。
主動句型：主詞+let＋受詞＋原形動詞.
被動句型：主詞＋be動詞＋allowed＋to＋原形動詞＋by＋受詞.
主動： My father let me go shopping with my friends.
被動：I was allowed to go shopping with my friends by my father.
Our teacher lets us eat in class.(我們老師讓我們上課吃東西)
→ We are allowed to eat in class by our teacher.
感官動詞被動語態
感官動詞後加原形動詞 (強調事實)
主動：I heard(過去式) the bird sing in the tree. (和使役動詞用法相同)
被動：The bird was heard(p.p.) to sing in the tree (by me).
主動： A +感官動詞 look at/watch/see/listen to/herar/feel +原型動詞(VR).
A+ be+ looked at/seen/watched/listened to/heard/felt/noticed +to rv＋by＋受詞. (A被看到做某事)
主動：Jack heard the bird sing this morning.(今天早上傑克聽到小鳥唱歌。)
被動: The bird was heard to sing this morning by Jack.
感官動詞後加Ving (強調看/聽/注意到某事進行的過程)
主動：I heard the bird singing in the tree.
被動：The bird was heard(p.p.) singing in the tree (by me).
主動： A +感官動詞 look at/watch/see/listen to/hear/feel +現在分詞(Ving)
A+ be+ looked at/seen/watched/listened to/heard/felt/noticed + 現在分詞(Ving) ＋by＋受詞.(A被看到做某事)
主動：Ivy saw the old lady crossing the road. Ivy看那位老婦人過馬路。
被動：The old lady was seen crossing the road by Ivy.
說明：感官動詞（see、hear、feel）在主動句中受詞補語是「原形動詞」，而在被動句中，原來的受詞補語要改成「to-V」形式。主動態為ving則維持不變，置於被動be+pp之後。
授與動詞被動語態
主動：A +give +B+ 物.
被動：B +be+p.p.+ 物 +by A.
主動：Tom gave Mary a comic book.
被動：Mary was given a comic book by Tom.
說明：主動句中的間接受詞（Mary）當被動式中的主詞時，不需介係詞。
主動： A give 物 to 人.
被動：物+be +p.p. +to /for B +by+ A
主動：Tom gave a book to Mary.
被動：A comic book was given to Mary by Tom.
說明：主動句中的直接受詞（a comic book）當被動式中的主詞時，需介係詞。
主動：Nancy bought Jack pearl milk tea. Nancy bought pearl milk tea for Jack.
被動：Pearl milk tea was bought for Jack by Nancy.
主動句中的直接受詞（pearl milk tea）當被動式中的主詞時，需介係詞。
【誤】Jack was bought pearl milk tea by Nancy 語意上，Jack不會被買。
含助動詞的被動語態
說明：may have pp指對過去可能的推測。
The machine should have been used by engineers only.
說明：should have pp指過去原本該做而沒做。
例如：Students have to do the homework by themselves.
The homework has to be done by students themselves.
1. 由於助動詞的關係，be動詞要用原形，而be動詞之後的結構不變。
2. 含助動詞的被動語態的否定句是將助動詞改為否定形式，而不是在be後面加not。
need的主詞為物時，以現在分詞表被動。
Need ving表被動
need的主詞為物時，以現在分詞表被動
例如：The dishes need washing.=The dishes need to be washed.
例如：The dishes need washing.→The dishes need to be washed.
表示客觀的說明，且說話者無特定對象時可用
It is ＋p.p. that 名詞子句句型（等於 People ……）
It is believed by many people that it is bad luck to enter the tomb.
→People believe that it is bad luck to enter the tomb.
其他常見片語有：It is said that….（據說）、It is reported…（據報導）、It is thought….（大家認為）
