24、 T: Yes.過去分詞作定語, 在語態(tài)上, 表被動; 在時間上, 表示動作已經(jīng)發(fā)生或完成, 與它所修飾的名詞有邏輯上的動賓關(guān)系。過去分詞作定語時, 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。 過去分詞作定語表示動作在謂語動作之前發(fā)生, 已經(jīng)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。例如: He is a teacher loved by his students.他是個很受學生愛戴的老師。 也有用不及物動詞的過去分詞作定語的情況, 一般作前置定語, 它不表示被動意義, 只表示主動意義, 強調(diào)

25、動作完成。不能像及物動詞的過去分詞那樣放在名詞后面作定語。例如: fallen leaves 落葉  retired workers 退休工人  the risen sun 升起的太陽 T: Now combine these two sentences using the past participle as the attribute. Soon we lost sight of that famous astronomer.He is called Li Qiang. S: Soon we lost sight of that famous astronomer c

27、empty.The room is connected to the rest of the house by a long passage. S: The room connected to the rest of the house by a long passage is completely empty. T: The queen was sitting in a royal carriage.The carriage was drawn by four horses. S: The queen was sitting in a royal carriage drawn by

28、 four horses. T: The vehicle is mentioned in the book.The vehicle is unknown to me. S: The vehicle mentioned in the book is unknown to me. T: The castle is under repair.It was built in 1432. S: The castle built in 1432 is under repair. T: Just now we practiced past participles used as attr

29、ibutes.There are still some notes we should pay attention to. 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。例如:  We needed much more qualified workers.我們需要更多的合格工人。 My friend is a returned student.我的朋友是個歸國的留學生。 單個分詞也可以作后置定語, 用以強調(diào)動作。例如:  They decided to change the material used.他們決定更換使用的材料。

30、 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, 其作用相當于一個定語從句。例如:  The student dressed in white is my daughter.(=The student who is dressed in white is my daughter.)穿白色衣服的學生是我的女兒。 3.如果被修飾的詞是由every/some/any/no+thing/body/one所構(gòu)成的復合代詞或指示代詞those等時, 即使一個單一的分詞作形容詞用, 也要放在被修飾詞的后面。例如: Is there anything unsolved?還有沒解決的

31、問題嗎？ There is noting changed here since I left this town. 自從我離開這個城鎮(zhèn)以來, 幾乎沒有什么變化。 4.單個過去分詞前加一個名詞或副詞, 常用連字符將它們連接起來構(gòu)成一個復合形容詞, 放在其修飾的名詞前, 作前置定語。分詞前加的名詞表示分詞的動作或行為主體, 所加的副詞表示方式、時間、程度、性質(zhì)等意義。例如:  This is a state-owned factory.這是一家國有工廠。 This is our school-run factory.這是我們的校辦工廠。 T: Now let’s learn

32、 past participles used as adverbials. 分詞作狀語分詞在句子中作狀語, 可以表示時間、條件、原因、結(jié)果、讓步、伴隨等。分詞作狀語時, 它的邏輯主語與句子的主語一致。作狀語的分詞相當于一個狀語從句。 例如:  Accompanied by his friend, he went to the railway station. Given better attention, the plants could grow better. He looked tired and depressed, visibly disturbed by th

34、 and setbacks.) 3.Inspired by the International, the working people of all countries have been fighting for their final liberation.(The working people were inspired/inspire the working people.) 4.No matter how frequently __________, the works of Beethoven always attract large audiences.(CET-4 19

35、95, 6) A.performing　 B.performed C.to be performed D.being performed 本句中貝多芬的作品被反復表演, 可見分詞與句子的主語之間是被動關(guān)系, 應該用過去分詞, 故答案為B。 5.__________as it was at such a time, his work attracted much attention.(CET-4 1996, 1) A.Being published B.Published C.Publishing D.To be published 本句中as引導的是讓步狀語從句,

36、 意思為: 他的作品盡管在被這樣的時候出版, 還是引起了關(guān)注, 可見分詞與句子的主語之間是被動關(guān)系, 應該用過去分詞, 故答案為B。 T: Now let’s combine these two sentences using the past participle as the adverbial. I was frightened by the loud noise.I went to see what was happening. S: Frightened by the loud noise, I went to see what was happening. T: H
