2、-ing形式的基本用法。

　　　 (1)作主語：Seeing is believing.百聞不如一見。Talking is easier than doing. –ing作主語時，如果其結(jié)構(gòu)較長，可用it作形式主語，而將作主語的-ing后置。如：It isn’t much good writing to them again. It’s no use waiting here.

　　　 (2)作表語：Her job is washing and cooking. My hobby is collecting stamps.

　　　 (3)作賓語：①作及物動詞的賓語。She likes drawing very much.；②作某些短語動詞的賓語。 Mary is thinking of going back to New York.；③ do+限定詞(my, some, any, the等)+ -ing，表示“做…事”之意，如：We often do our cleaning on Saturday afternoon. Will you do any shopping on Saturday this afternoon? ④作介詞的賓語：Her sister is good at learning physics.；⑤作形容詞worth, busy等的賓語：This book is well worth reading. –ing作賓語帶有賓語補足語時，要用it作為形式賓語，而將作賓語的-ing后置，如：We found it no good talking like that. Do you think it necessary trying again?

　　　 (4)作定語：The sleeping child is only five years old. Do you know the man standing at the gate? 注：-ing形式作定語用時，如果-ing只是一個單詞，就位于其修飾的名詞之前，如果是-ing短語，就位于其修飾的名詞之后，-ing作定語時，被-ing所修飾的名詞就是該-ing的邏輯主語。另外，-ing作定語用時，其動作和句子謂語動詞所表示的動作是同時進行的，如果不是同時進行的，就不能用-ing作定語，要使用定語從句，如：The girl who wrote a letter there yesterday can speak English very well.

　　　 (5)作賓語補足語：We can see steam rising from the wet clothes. 注：當-ing在復合賓語中作賓語補足語用時，句中賓語就是這個-ing的邏輯主語，可以帶有這種復合賓語的動詞有see, watch, hear, observe, feel, find, have, keep等。

　　　 (6)作狀語：①時間狀語：Seeing Tom, I couldn’t help thinking of his brother. 分詞在句中作時間狀語時，其前一般可加when或while，如：When crossing street, you must be careful. ②原因狀語：Being ill, he didn’t go to school yesterday. ③方式或伴隨狀語：Mary stood at the school gate waiting for Betty.

1、-ing的形式：-ing有一般式和完成式。及物動詞的-ing還有主動語態(tài)和被動語態(tài)，而不及物動詞的-ing則沒有被動語態(tài)�，F(xiàn)在以及物動詞make 和不及物動詞go為例，將其-ing各種形式列表如下：

38. ---- What do you think about English?　　　　　 ---- It's a difficult language _____.

A. speaking　　　　　 B. to be spoken　　　 C. to speak　　　　　 D. spoken
