單元語法
過去分詞作表語與狀語
1 過去分詞作表語
（1）過去分詞可放在連系動詞 be，get，feel，remain，seem，look，become 等之后作表語，表示主語所處的情緒或狀態(tài)。
Please remain seated；the winner of the prize will be announced soon.請繼續(xù)坐著，獎品的獲得者很快就會宣布。 ［詞匯復現(xiàn)］
（2）過去分詞作表語與被動語態(tài)的區(qū)別
“be+ 過去分詞”表示狀態(tài)時，是系表結構，此時分詞通常已形容詞化；表示動作時，是被動語態(tài)，且絕大多數(shù)被動結構中的動作執(zhí)行者由介詞 by 引出。
Brian was relaxed when he was sitting on the sofa and watching TV.布賴恩坐在沙發(fā)上看電視時感到很放松。
The whole city was destroyed by the terrible disaster.整個城市被可怕的災難摧毀了。 ［詞匯復現(xiàn)］
（3）英語中有很多與感覺有關的使令動詞，其現(xiàn)在分詞表示主動意義，
即“令人……的”，多用來修飾物；其過去分詞表示被動意義，即“感到……的”，多用來修飾人、人的聲音或表情等。常用的這類詞有：
They were shocked to know that some people died of the unknown
disease. 得知一些人死于這種未知的疾病，他們感到震驚。 ［詞匯復現(xiàn)］
Although the little girl was frightened，she answered in a calm voice.
雖然小女孩很害怕，但她還是用平靜的聲音回答。
【學法點撥】
有些使令動詞，如 dress，seat，absorb 等，其過去分詞無論作定語還是表語，都無被動的意味。因為 dress oneself in 等于 be dressed in；seat oneself on 等于 be seated on；absorb oneself in 等于 be absorbed in，這種現(xiàn)象緣于反身代詞的用法：主語和賓語同為一人，主語是動作的
發(fā)出者，又是動作的承受者，這就出現(xiàn)了被動語態(tài)或過去分詞不表
示“被動”的語言現(xiàn)象。
2 過去分詞作狀語
過去分詞（短語）作狀語，表示動作發(fā)生的背景或情況，其邏輯主語是句子的主語。過去分詞（短語）在句中作狀語可以表示時間、條件、方式或伴隨、讓步、原因等。
（1）表示時間 過去分詞（短語）作時間狀語，相當于一個時間狀語從句。
Asked why he did it（=When he was asked why he did it），the monitor said it was his duty.當被問到他為什么這么做時，班長說這是他的職責。
（2）表示條件 過去分詞（短語）作條件狀語，相當于一個條件狀語從句。
Given better attention（=If it were given better attention），the accident could have been avoided.如果當時多加注意，事故本來是可以避免的。
（3）表示方式或伴隨 過去分詞（短語）作方式狀語或伴隨狀語，可以轉(zhuǎn)換成一個并列句。
The patient got off the bed，（and he was）supported by the nurse.那個病人在護士的攙扶下下了床。
（4）表示讓步 過去分詞（短語）作讓步狀語，相當于一個讓步狀語從句。
Encouraged by his parents（=Although he was encouraged...），he still has no confidence in overcoming the difficulties. 盡管受到了父母的鼓勵，他仍然沒有信心克服困難。 ［詞匯復現(xiàn)］
