感官動詞（知覺動詞）：
一、基本定義：凡是和身體五官的感覺或動作有關的動詞就叫做感官動詞，包括
see, watch, look at, hear, listen to, smell, feel, notice 等動詞
二、感官動詞的後面要加原形動詞或現在分詞：接原形動詞時表示動作發生過；
接現在分詞時強調動作正在進行
1. I saw him enter (entering) the theater.
2. I see him go for a walk in the park every day. (由於副詞片語 every day，我們知道
這個動作經常在發生，並不是一時一刻正在進行的動作，所以感官動詞後不能接
現在分詞，不能寫成 I see him going for a walk in the park every day.)
3. When he was singing, I just passed by, so I heard him singing.
4. Do you feel the earth moving now?
5. I smell something burning now.
6. I looked at him drawing (draw) a picture.
7. I listened to the teacher giving the lecture.
三、感官動詞的後面如果要表示被動的話，則要加過去分詞
1. I saw him repair his car. = I saw his car repaired by him.
2. I‘ve heard him tell the same story many times.
= I’ve heard the same story told many times by him.
3. I saw him steal the car. = I saw the car stolen by him.
