(3) The falling leaves indicate that our prey is on the tree. v-ing形式在英語中有兩種稱呼，分別為①______(如Knowing is important.)和②______(如the falling leave)。v-ing可以在句中充當(dāng)除③______外的所有成分。句(1)中充當(dāng)④_____, 句(2)中充當(dāng)⑤______,句(3)中充當(dāng)⑥______。 [具體用法] (一)成分分析 1. 作主語：此時的-ing是動名詞，看成單數(shù)，常用it作形式主語，把v-ing放于句末。常見句型有： It be a waste+v.-ing; It be no good/use+v.-ing; There be no sense in+v.-ing; There be no point in+v.-ing 2. 作賓語：此時的v.-ing為動名詞，常出現(xiàn)在某些不能用不定式作賓語的動詞后。如：enjoy, advise, admit, appreciate, forbid, feel like, be accustomed to等后。 I can’t imagine working outdoors in such a cold day. 3. 作定語：此時的v.-ing既可以是動名詞，也可以是現(xiàn)在分詞。但動名詞表示該名詞的用途或有關(guān)的動作；而現(xiàn)在分詞作定語則用于說明所修飾名詞正在進行的動作。如 dining room(動名詞 ) a waiting room(動名詞) a waiting man(現(xiàn)在分詞) 4. 作表語：此時的v.-ing既可以是動名詞，也可以是現(xiàn)在分詞。動名詞作表語是對主語內(nèi)容的解釋，這時主語與表語位置可以互換；現(xiàn)在分詞作表語，表明的是主語的性質(zhì)與特征，主語與表語的位置不能互換。 Our job is playing all kinds of music. (動名詞作表語) =Playing all kinds of music is our job. The music they are playing sounds exciting. (現(xiàn)在分詞作表語) 5. 作賓語補足語：此時的v.-ing是現(xiàn)在分詞，主要用于以下兩類動詞后構(gòu)成賓語補足語。 感官動詞，如：see, hear, feel, smell, watch, find, notice等。 I felt someone patting on the shoulder. 使役動詞，如have，keep, leave等。 I am sorry to have kept you waiting long. The young mother left her baby crying. 6. 作狀語：此時的v.-ing是現(xiàn)在分詞。-ing形式作狀語，可以表示時間、原因、結(jié)果、條件、讓步、行為方式、伴隨狀語等。 Not knowing Chinese, he couldn’t understand the film. (原因狀語) The children went into the classroom, talking and laughing. (伴隨狀語) 注：分詞（短語）作狀語時，其邏輯主語必須與句子的主語保持一致，如果不一致，必須用獨立主格結(jié)構(gòu)來表示，也就是在分詞前面加上它自己的主語。Finding her car stolen, she hurried to a policeman for help. (分詞作狀語) The train having gone, we had to wait another day. (獨立主格) （二）-ing形式的完成式 1. 主動：Having+過去分詞……，主語+謂語。 Having answered the letter, she went on to read an English novel. -ing形式的完成式所表示的動作發(fā)生在句子中謂語動詞所表示的動作之前。 2. 被動：（Having been）+過去分詞……，主語+謂語。 Having been shown the lab, we were taken to see the library. -ing的完成被動式所表示的動作與邏輯主語之間是被動關(guān)系，發(fā)生在句中謂語動詞所表示的動作之前。 [用法檢測]用動詞的v-ing形式改寫下列句子 (1) As I came out of my house，I saw the volcano erupting. →________________，I saw the volcano erupting. (2) She sat at the desk and read a newspaper. →She sat at the desk _________________. (3) As I had never seen a volcano erupting before，I was very excited. →_________________________________，I was very excited. (4) It rained heavily so that it caused severe flooding in the area. →It rained heavily，________________________________.

Since the end of last year, fog and haze weather has occurred a lot in some areas of China, which has done great harm to our daily life. Many traffic accidents happened just because of the heavy fog and haze. Besides, more and more citizens have to go to see the doctor because of the serious disease caused by the fog and haze. Now that we have realized the great harm caused by the fog and haze, we should take measures to reduce fog and haze weather. The government should suggest people to go to work or school with the public transportation, such as the bus and the underground. Also more trees should be planted. As for me, I will go to school by bike or on foot. Would you join us in protecting the environment? Thank you.
