12.---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

　　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。

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

　　A. them  B. which  C. it  D. what

　　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后面沒有并列連詞and, but。但是，ship在這里是一個及物動詞，意思為“運送……到”，也就是說這里的shipped是一個過去分詞，后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。

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

　　A. whoever          B. whomever

　　C. who              D. those

　　選A。 作賓語從句的主語；he believed可視為插入語。

　　15. — 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

　　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。

　　16.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

　　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。

　　17. Is it true _____ the rain stops, it will be as hot as in the summer here?

　　A. when   B. that when   C. whenever  D. that

　　選B。本題考查學生分析句子結構的能力。It is true that構成一個主語從句，而主語從句內部又有一個以when引導的時間狀語從句。

　　18.Mike, as far as I know, _______ like to play music.

　　A. seems  B. appears  C. feels  D. does

　　選D。as far as I know為插入語，去掉插入語后，在結合like后面的不定式可以知道like為動詞而不是介詞，故排除A、B、C。D項does+動詞原形表示強調，意思為“的確，確實”。

　　19.The time he has devoted in the past years _______ the disable is now considered ________ of great value.

　　A. to help; being      B. to helping; to be

　　C. to help; to be      D. helping; being

　　選B。前一部分考查devote one’s time to doing sth句式。其中devote的賓語the time在定語從句中提到了前面并省略了；后一部分中的consider的后面接了主語補足語，所以用不定式作補語。整個句子的意思為：他在過去的十年中用在幫助殘疾人身上的時間現在被認為是很有價值。

　　20._______ different life today is ________ what it was 30 years ago.

　　A. How; from  B. What a; from

　　C. What; from  D. How; with

　　選A。由于受a…life的影響，容易選B。實際上本句主句的主語是life today，而different from 是主句的表語�？梢园阉�變成普通句式：Life today is different from what it was 30years ago.
