1.________ not to miss the flight at 15∶20，the manager set out for the airport in a hurry.

A.Reminding B.Reminded

C. To remind D.Having reminded

解析：選B.句意：有人提醒經理不要錯過15∶20的航班，他匆忙出發去瞭機場。本題考查非謂語動詞作狀語。主句主語the manager與remind之間的關系為邏輯上的動賓關系，故排除A、C、D三項，因為這三項表主動，而隻有B項表被動。

2.Dina,________ for months to find a job as a waitress,finally took a position at a local advertising agency.

A.struggling B.struggle

C.having struggled D.to struggle

解析：選C.此處分詞短語作時間狀語，其邏輯主語Dina與struggle為主動關系，故排除B項。由句中的finally可知非謂語動詞表示的動作發生在句中謂語took a position之前，故用現在分詞的完成主動式。

3.________ the right kind of training,these teenage soccer players may one day grow into international stars.

A. Giving B.Having given

C.To give D.Given

解析：選D.考查非謂語動詞。如果把句子補充完整應該是：If they are given the right kind of training,可知主語they即these teenage soccer players與give之間是被動關系，所以用過去分詞。而A、B、C三項都不表示被動含義。

4.________ many times,he finally understood it.

A.Told B.Telling

C.Having told D.Having been told

解析：選D.考查非謂語動詞。tell與主語之間的關系是被動關系，故排除表示主動意義的B項和C項。由狀語many times可知tell這一動作在謂語動詞understand之前發生過多次，所以用having been done來表示被動和完成。

5.________ by the advances in technology,many farmers have set up wind farms on their land.

A.Being encouraged B.Encouraging

C.Encouraged D.Having encouraged

解析：選C.考查非謂語動詞。由於主語many farmers和作狀語的encourage之間是被動關系，排除表示主動意義的B項和D項。而being encouraged除表示被動外，還表示進行。農民們顯然不是正在受到科技進步的鼓舞，故排除A項。

6.________ in 1636，Harvard is one of the most famous universities in the United States.

A.Being founded B.It was founded

C.Founded D.Founding

解析：選C.分析句子結構可知應選考查非謂語動詞形式作狀語的，排除B項，另外found與Harvard之間為被動關系，應用過去分詞形式作狀語，故選C.

7.________ as the "First Lady of Speech"，Dr Lillian Glass is recognized as one of the world’s leading experts on communication skills.

A.Knowing B.Having known

C.Known D.To be known

解析：選C. be known as被稱為……。Dr Lillian Glass與know之間為被動關系，應用過去分詞形式作狀語。A、B表主動，應排除;D項表將來，也可排除。

8.________ more attention,the trees could have grown better.

A.Given B.To give

C.Giving D.Having given

解析：選A.考查分詞作狀語。句子主語the trees與give之間是被動關系，而四個選項中隻有A項表示被動意義，故答案選A.Given more attention相當於一個條件狀語從句If the trees were given more attention.

9.________ in thought,he almost ran into the car in front of him.

A.Losing B.Having lost

C.Lost D.To lose

解析：選C.考查分詞作狀語。句意：由於陷入沉思，他差一點撞到前面的車上。be lost in thought為固定搭配，意為“陷入沉思”。過去分詞短語lost in thought在句中作原因狀語。

10.The research is so designed that once ________ nothing can be done to change it.

A.begins B.having begun

C.beginning D.begunw

解析：選D.考查分詞作狀語。句意：這項調查研究事先計劃的如此完好，以至於一旦開始，什麼也無法改變它。begin與research之間是被動關系，排除表示主動意義的A、B、C三項。once begun在句中作條件狀語，它是狀語從句once it is begun的省略形式。

11.Generally speaking,________ according to the directions,the drug has no side effect.

A.when taking B.when taken

C.when to take D.when to be taken

解析：選B.考查分詞作狀語。完整的說法應是when the drug is taken according to the directions……。由於主句的主語和從句的主語相同，因此可以省略從句的主語the drug和謂語的一部分is,故答案為B.

12.________ into use in April,2000，the hotline was meant for residents reporting water and heating supply breakdowns.

A.Put B.Putting

C.Having put D.Being put

解析：選A.考查過去分詞作狀語。句子的主語是the hotline與put into use“投入使用”存在被動關系，排除表示主動的B項和C項。D項表示正在投入使用，不符合語境。

http://13.In order not to be found,I spent the whole night ________ in my room.

A.locking B.locked

C.to lock D.lock

解析：選B.考查過去分詞作狀語。句意：為瞭不被找到，我整晚上都把自己鎖在自己的房間裡。lock的邏輯主語I和lock之間存在被動關系，故用過去分詞作伴隨狀語。本題易受“spend…… doing sth.句型的影響，易誤選A.其實我並不是把整晚上的時間都用在瞭“鎖”這一動作上，故排除A.

14.________，liquids can be changed into gases.

A.Heating B.To be heated

C.Heated D.Heat

解析：選C.考查過去分詞作狀語。句意：被加熱時，液體可以變成氣體。由於對於液體來說是加熱的承受者，是被動的，因而選C.A項表示主動，B項表示目的，D項是謂語動詞的形式。

15.Unless ________ to speak,you should remain silent at the conference.

A.invited B.inviting

C.being invited D.having invited

解析：選A.考查過去分詞作狀語。句意：除非受到邀請講話，否則在大會上你應該保持沉默。invite與you之間是被動關系，排除B、D.being invited表示正在受到邀請，不符合語境。

16.---Good evening. I _______ to see Miss Mary.

---Oh, good evening. I’m sorry, but she is not in.

A. came B. come C. have come D. had come

解析：選C。本題主要考查動詞時態的用法。選項A表示過去所發生的事情；B表示經常性或習慣性的動作；C表示目前的情況和影響；D時態不符合對話的時間和語境。

17.The factory produced many famous cars, none of ____ shipped to foreign countries.

A. them B. which C. it D. what

解析：選A。本題容易誤選B。容易被認為是一個非限制性定語從句。理由是none後面沒有並列連詞and, but。但是，ship在這裡是一個及物動詞，意思為“運送……到”，也就是說這裡的shipped是一個過去分詞，後面的部分是一個獨立主格結構。如果在shipped前面加一個was，則應該選B，構成非限制性定語從句。

18. The manager decided to give the job to ____ he believed had a strong sense of duty.

A. whoever B. whomever

C. who D. those

解析：選A。 作賓語從句的主語；he believed可視為插入語。

19. — Tod hadn’t passed the exam and was afraid of being scolded.

— _____.

A. So it was with Jim

B. So was Jim, his classmate

C. It’s the same with Jim

D. Neither had Jim, his classmate

解析：選A。So it was with Jim是指上一句的內容也適合另一個人。如選項C中It’s改為It was才對。

20.The Indian Ocean tsunami at the end of 2004 is believed _____ more than 160,000 people and made millions homeless, _______ it perhaps the most destroying tsunami in history.

A. to kill; making B. to have killed; making

C. having killed; to make D. killing; made

解析：選B。本題考查句型結構及非謂語動詞的意義。根據believe句型，believe sb. /sth to be/ to have done可以知道，第一空填to have killed;第二空的非謂語動詞表示結果，動詞的-ing形式表示事情發展的自然結構，而不定式表示出乎意料的結果。
