被動語氣

英文句的最重要規則之一：需要且唯有一個動詞

1. He was a student before.

2. He went to school yesterday.

3. He swims every morning.

4. I saw you yesterday.

5. He wrote two novels.

6. He hit a dog.

上面6個例子中，1-3是屬於不及物動詞（不需要受詞），4-6屬於及物動詞（需要受詞）。

及物動詞句型改成被動語氣(passive voice)

l 中文裡「我打了一隻狗」的被動：「一隻狗被我打」。

英文裡也類似，但不同的是動詞形式的改變。

（還記得嗎，之前上時態的時候曾說過，英國人看動詞就可以知道時間概念，這裡也是一樣的，看動詞知道主動或被動）

l I saw a cat. 我看到一隻貓。 Saw (see)改為：be動詞＋過去分詞(pp)

A cat was seen by me. 一隻貓被我看到。 Saw：過去式, was：過去式, seen：過去分詞

1. He saw the movie last night.

2. He wrote that letter to me.

3. God loves you.

4. I sold the house.

5. My uncle bought this car.

練習：將以下句子由被動改為主動語氣。

1. His door was locked by me.

2. His bout was given to me by my father.

3. He is liked by everyone.
