學
本章學習目標
分辨主動和被動
知道什麼情況下要用被動句。
學會主詞變化
知道主詞是接受動作的一方，不是做動作的人。
1
白話解釋
被動語態用來說「某事被做了」。主詞不是做事的人，而是被動作影響的對象。
句型重點
The cake was eaten by Tom.（蛋糕被 Tom 吃掉了。）
The window is broken.（窗戶被打破了。）
被動句的結構是：主詞 + be + 過去分詞 (+ by + 行動者)。
2
常見錯誤
錯誤 1：忘了 be 動詞
The letter sent by her.
The letter was sent by her.
錯誤 2：把主動式當被動式用
The homework do by me.
The homework was done by me.
錯誤 3：用錯時態
The book is wrote by him.
The book was written by him.

正確句型
現在被動：is / am / are + 過去分詞
The cake is eaten. / I am helped.
過去被動：was / were + 過去分詞
The homework was done. / They were invited.
被動句常用 + by + 行動者
The song was sung by her.
