52、 quick learners from others. It really likes humans and as we are now friends, it wants to become a human being too. Step 3. Discovering useful structures 1. Individual work Give Ss two sentences in which the past participle is used as an adverbial phrase. Eg Worried about the journey, I was un

53、settled for the first few days. Then ask Ss to find other three sentences from the reading passage with the past participle used as the adverbial. (1) Well-known for their expertise, his parent’s company… (2) Confused by the new surroundings, I was hit by the lack… (1) Exhausted, I slid into bed

54、… Let’s Ss discuss the usage of past participle and find some grammar usages. 2. Explanation of the grammar. (1) 和現在分詞一樣，過去分詞或過去分詞短語也可以充當副詞，修飾謂語動詞。 過去分詞可以表達下列四種意思： ① 方法或活動方式，如： He walked up and down, lost in thought I sat before the desk until after mid-night, absorbed in writing. Surrou

55、nded by a host of fans, the film star left the airport excitedly . ② 原因，如： Greatly disappointed, some staff decided to leave the place. Taken by surprise, the enemy surrendered. ③ 時間，如： Born and bred in a turbulent age, the older generation of people experienced all sorts of hardships. Thr

56、own to the floor, the boy regained his footing a few minutes later . ④ 條件，如： Given more time, the slow learners would have done better . Criticized by someone else, Tony would not have fared up like that. (2) 除了直接修飾動詞之外， 過去分詞或短語也可以和連詞組成短語，表示下列四種意思： ① 由 when ,whenever , while until等連詞引導，表示“時間

57、”，如： When asked about his previous job, Bill said he had been a motor mechanic. Susan seldom speaks in class until spoken to. ② 由where , wherever 連詞引導，表示“地點”。 Mosquitoes should be completely exterminated where found. Retires in good health should be invited to return to work wherever needed.

58、 ③ 由if , unless引導，表示“條件”，如 If kept for too long, some medicines will lose their effectiveness. We have made a point of not attacking unless attacked. ④ 由 though, although , even though 連詞引導，表示“讓步”，如： Though warned of the danger, they still went mountaineering. Even though defeated for a se

59、cond time, our team did not give up hope for the ultimate victory. IV Studying the past participle as the attribute. (3) 過去分詞做定語, 在語態(tài)上表被動，在時間上表示動作已經發(fā)生或完成，與它所修飾的名詞有邏輯上的動賓關系。 過去分詞做定語時， 所修飾的名詞在邏輯上相當于被動句中的主語，過去分詞相當于謂語。 (4) 過去分詞作定語表示動作在謂語之前發(fā)生，已經完成并具有被動意義。有時也不表示時間性。作定語的過去分詞一般由及物動詞變來，因為只有及物動詞才有被動意義

60、。如： He is a teacher loved by his students. 他是個很受學生愛戴的老師。 (5) 也有不及物動詞作定語的情況，一般作前置定語，它不表示被動意義，只表示主動意義，強調動作完成。不能像及物動詞的過去動詞那樣放在名詞后面作定語。如： fallen leaves, retired workers , the risen sun 注意下面過去分詞作定語的幾種情況： ① 單個的過去分詞作定語一般放在被修飾的名詞之前。如： We needed much more qualified workers My friend is a retu

61、rned student. ② 過去分詞短語作定語要放在被修飾的名詞后面，作后置定語，其作用相當與一個定語從句。如： The student dressed in white is my daughter = The student who is dressed in white is my daughter. ③ 如果被修飾的詞是由every /some/any / no+thing /body/one 所構成一個復合代詞或指示代詞those 等時，即使一個單一的分詞做形容詞，也要放在被修飾詞的后面。例如： Is there anything unsolved? There i

62、s nothing changed here since I left this town. ④ 單個過去分詞前加一名詞或副詞，常用連字符將它們連起來構成一個復合形容詞，放在其修飾詞前，作前置定語。 This is a state-owned factor. This is our school –run factory. ⑤ 作前置定語的某些動詞的過去分詞的形式與作謂語或表語的過去分詞的形式往往不一樣。例如： 原形 用作定語的過去分詞 用作表語或謂語的過去分詞 drink drunken drunk light lighted lit

63、melt melten melted sink sunken sunk We lit the candle and the candle lit up the room. 我們點著蠟燭，蠟燭照亮房間。 There is a lighted candle on the table. 桌上有一只點著的蠟燭。 2. Pair work (1) In pairs combine these two sentences using the past participle as the adverbial. ① I was frightened by the loud
