導讀:

  考研英語之所以難是由于文章中到處都充斥著長難句,也就是句子不僅長而且結構復雜。而讀懂這些長難句是我們解題的關鍵之所在。要想讀懂,我們得學會去拆分,去識別出句子所包含的重要語法現象,其中關于獨立主格結構是一個重難點。那么,接下來,由老師梳理下相關知識點。

  (一)基本構成形式

  名詞(代詞)+現在分詞/過去分詞/形容詞/副詞/不定式/名詞/介詞短語

  1.名詞(代詞)+現在分詞

  There being no bus,theyhad to walk home.

  
  2.名詞(代詞)+過去分詞

  She was listening attentively in class, hereyes fixed on the blackboard.

  
  3.名詞(代詞)+不定式

  在此結構中,動詞不定式和前面的名詞或代詞若存在著邏輯上的主謂關系,動詞不定式則用主動的形式;若是動賓關系,則用被動形式。

  The four of us agreed on a division of labor, each to translate a quarter of the book.

  Many trees, flowers, and grass to be planted, our newly-built school will look even morebeautiful.

  
  4.名詞(代詞)+形容詞

  Computers very small, we can use them widely.

  
  5.名詞(代詞)+副詞

  The meeting over, our headmaster soon left the meeting room.

  
  6.名詞(代詞)+名詞

  His first shot failure,he fired again.

  
  7.名詞(代詞) +介詞短語

  Every afternoon a very old woman hobbled past the old house,a vast load of firewood on her back.  

  (二)with/without引導的獨立主格結構

  with/without+賓語(名詞/代詞)+賓語補足語,賓語通常由名詞或代詞充當,但代詞一定要用賓格。在with (without)的復合結構中,多數情況下with能省略,但without不能省略。

  The girl hid her box without anyone knowing where it was.

  Without a word more spoken, she left the meeting room.

  The kid feels excited with so many places of interest to visit.

  
  (三)獨立主格結構的句法功能

  獨立主格結構在句中一般作狀語,表示時間、條件、原因、伴隨狀況等,可以看成是一個狀語從句的省略。

  
  1.作時間狀語

  The governor pondering the matter,more strikers gathered across his path.

  
  2.作條件狀語

  Weather permitting,they will go on an outing to the beach tomorrow.

  
  3.作原因狀語

  The boy leading the way, we had no trouble finding the strange cave.

  
  4.作伴隨狀語或補充說明

  Ten students entered for the competition, the youngest a boy of 12.

  
  (四)注意事項

  1.獨立主格結構的邏輯主語與句子的主語不同,它獨立存在。名詞或代詞與后面的分詞等邏輯上是主謂關系,獨立主格結構一般有逗號與主句分開。

  The president assassinated, the whole country was in deep sorrow.

  
  2.動詞不定式表示動作沒有發(fā)生或即將發(fā)生,動詞-ed形式表示動作已經結束,動詞-ing形式往往表示動作正在進行。

  The manager looks worried,many things to settle.

  (事情還沒有處理,而且是由經理本人來處理,用不定式to settle,表示將來的時間)

  The manager looks relaxed, many things settled.

  (事情已經處理好了,用過去分詞settled表示動作已經結束)

  The food being cooked, the boy was watching TV.(兩個動作同時進行)

  
  3.獨立主格結構與分詞短語都可以轉換為狀語從句。但是獨立主格結構轉換為狀語從句后,它有自己的邏輯主語,與主句的主語不一致;而分詞短語轉換為狀語從句后,從句的主語與主句的主語一致。

  If time permits, we'd better have a holiday at weekends.(條件狀語從句)

  Time permitting, we'd better have a holiday at weekends.(獨立主格)

  When we see from the hilltop, we can find the city more beautiful.(時間狀語從句)

  Seeing from the hilltop, we can find the city more beautiful.(現在分詞)
