11.Nowadays ________ Internet is becoming increasingly popular and new high speed broadband network was recently started.

A. a; the B. the; a C. a; a D. the; the

选B。本题主要考查冠词的用法。Internet为特指对象;而一条高速的新宽带网为泛指，用不定代词a。

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

选C。本题主要考查动词时态的用法。选项A表示过去所发生的事情;B表示经常性或习惯性的动作;C表示目前的情况和影响;D时态不符合对话的时间和语境。

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

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

选A。本题容易误选B。容易被认为是一个非限制性定语从句。理由是none后面没有并列连词and, but。但是，ship在这里是一个及物动词，意思为“运送……到”，也就是说这里的shipped是一个过去分词，后面的部分是一个独立主格结构。如果在shipped前面加一个was，则应该选B，构成非限制性定语从句。

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

选A。 作宾语从句的主语;he believed可视为插入语。

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

选A。So it was with Jim是指上一句的内容也适合另一个人。如选项C中It’s改为It was才对。

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

选B。本题考查句型结构及非谓语动词的意义。根据believe句型，believe sb. /sth to be/ to have done可以知道，第一空填to have killed;第二空的非谓语动词表示结果，动词的-ing形式表示事情发展的自然结构，而不定式表示出乎意料的结果。

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

选B。本题考查学生分析句子结构的能力。It is true that构成一个主语从句，而主语从句内部又有一个以when引导的时间状语从句。

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

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

选D。as far as I know为插入语，去掉插入语后，在结合like后面的不定式可以知道like为动词而不是介词，故排除A、B、C。D项does+动词原形表示强调，意思为“的确，确实”。

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

选B。前一部分考查devote one’s time to doing sth句式。其中devote的宾语the time在定语从句中提到了前面并省略了;后一部分中的consider的后面接了主语补足语，所以用不定式作补语。整个句子的意思为：他在过去的十年中用在帮助残疾人身上的时间现在被认为是很有价值。

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

A. How; from B. What a; from

C. What; from D. How; with

选A。由于受a…life的影响，容易选B。实际上本句主句的主语是life today，而different from 是主句的表语。可以把它变成普通句式：Life today is different from what it was 30years ago.
