1．分詞的性質：

3．分詞的用法：
（1）定語 分詞置於被修飾名詞前
分詞短語於置於被修飾名詞後
a sleeping baby = a baby who is sleeping
a running dog = a dog which is running
a broken glass = a glass which is broken

The news is exciting.
He feels excited.
（3）賓語補足語：

（4）狀語：（以下例句值得一背！）
① If you turn to the left, you'll find the station.
→ Turning to the left, you'll find the station.
② As I didn't receive her letter, I called her up by telephone.
→ Not receiving her letter, I called her up by telephone.
③ While I was walking to school yesterday morning, I met a friend.
→ Walking to school yesterday morning, I met a friend.
④ When she was asked it she had any bad habit, she answeredthat she was a heavy smoker.
→ Asked if she had any bad habit, she answered that she was a heavy smoker.
注意：在運用此類句型時主語前後要保持一致。
① Whenschool was over, the boys went home.
→ Being over, the boys went home. ×
School being over, the boys went home. √
② As my homework has been done, I have nothing else to do.
→ My homework having been done, I have nothing else to do.
③ Ifweather permits, I'll start tomorrow.
→ Weather permitting, I'll start tomorrow.
④ I fwe judge from his face, he must be ill.
→ Judging from his face, he must be ill.（這裏應該是 we judging ...，但若主語是we, one, you表示“一般人”，主語可省略）
實際上，這裏涉及到獨立主格結構問題，以後在作分解！
4．分詞的時態：
現在分詞一般時表示此動作與主句謂語動詞同時發生。
現在分詞完成時表示此動作在主句謂語動詞之前發生。
Entering the room, hesaw he. （幾乎同時）
Not having tried his best, he failed in the exam. （分詞動作在前）
5．語態：
現在分詞一般時被動表動作正在被進行，完成時被動強調分詞所表示的動作先被完成。

Having been warned of typhoon, the fishermen sailed for the nearest harbor.（漁民先被告知而後駛向港口）
