　　Step 3 Discovering useful structures

　　過去分詞作狀語

　　1. 觀察探究

　　(1)作原因狀語,多放在主句之前,相當于because, since, as引導的從句.

　　Tired from the day's hard work, he fell asleep soon.=(Because he was tired from the day's hard work, he...)

　　(2)作時間狀語,相當于when引導的時間狀語,有時在分詞前直接加when, while, until等詞可使其表達的時間意義更明確.如:

　　When heated, water can be changed into steam. Seen from the hill, the town looks beautiful.

　　(3)作條件狀語,相當于if, unless引導的從句.

　　Given another chance, he can do it better.=(If he is given another chance,...)

　　(4)作讓步狀語.

　　Much tired, he still kept on working. (=Though he was much tired, he...)

　　(5)作方式或伴隨狀語.

　　Lost in thought, he almost ran into the car in front of him. The teacher stood there, surrounded by many students.

　　2. 用法歸納

　　過去分詞作狀語，與主句主語之間是        關系，相當于一個狀語從句,可表        、

　　、         、           、                。注意:(1).過去分詞作狀語,有時前面帶有連詞,是狀語從句的省略形式,省去主語和be,通常主語與主句的主語相同.

　　when (it is)heated, water will boil.

　　（翻譯）____________________________________________

　　She won't go to the party, unless (she is)invited.

　　（翻譯）____________________________________________

　　(2).過去分詞與句子的主語在邏輯上是動賓關系，而現在分詞與其邏輯主語則是主謂關系.

　　Seeing in this light, the matter is not as serious as people generally suppose. (改錯)

　　(3)過去分詞作定語不僅表示被動,還表示已經完成,但過分作狀語,動作不一定是已經完成的動作,有可能是同時進行的,也有可能是未來的.(尤其在時間,條件狀語從句中).

　　Once to be begun, the project will not changed. (改錯)

　　If to be given more money, I will solve the problem soon. (改錯)

　　(4)過去分詞作狀語,相當于對應狀語從句,不可再用but, so, and, or否則重復.

　　Laughed at by everyone, but he had my sympathy. (改錯)

　　Known to all, so he was recognized very easily. (改錯)

　　(5)過去分詞的邏輯主語要與句子的主語保持一致,否則用從句或獨立結構.

　　No matter how well translated, we don't like it. (改錯)
