27． They wanted to charge $ 5, 000 for the car, _________we managed to bring the price down .

　A． but　　　　　　　　　　 B． so　

　C． when　　　　　　　　　 D． since

　[解析] 本题考查连词的用法。根据前后两句的意思，“他们想对那辆车要价5，000美元，我们设法把价格降了下来”，说明前后两句意思发生了转折，应选连词but。答案为A。

26． Tom, you ______ leave all your clothes on the floor like this!

　A． wouldn’t　　　　　　　 B． mustn’t　

　C． needn’t　　　　　　　　 D． may not

　[解析] 本题考查情态动词的用法。从感叹号的语气来看，说话人是命令的口吻，“Tom，你不准像这样把所有的衣服都撂在地上！”mustn’t有“禁止，不准”的意思，语气非常强烈，而needn’t“没必要”，may not“或许不”，wouldn’t“不愿意”不管在语气还是在意思上都与语境不符。答案为B。

25． We haven’t enough books for______; some of you will have to share.

　A． somebody　　　　　　　 B． anybody　

　C． everybody　　　　　　　 D． nobody

　[解析] 本题考查代词的用法。本题的第二句话给出了语境，“你们中有些人得合用”。这说明前一句话是说“我们没有足够多的书给每一个人”。答案为C。

24． I have many friends, _______ some are businessmen.

　A． of them　　　　　　　 B． from which　

　C． who of　　　　　　　 D． of whom

　[解析] 本题考查“介词+关系代词”引导的定语从句。观察此题，可以看出句中有一个逗号，前后是两个句子，说明这是一个含有非限制性定语从句的主从复合句，排除选项A。选择“介词+关系代词”引导定语从句的介词时，应将先行词放到定语从句中，看其在定语从句中是与哪个介词搭配的。本题的定语从句部分还原为简单句应为“some of them(my friends) are businessmen.”或“of them(my friends) some are businessmen.”因此答案为D。

23． Mary wrote an article on_______ the team had failed to win the game .

　A． why　　　　　　　　　　 B． what　

　C． who　　　　　　　　　　 D． that

　[解析] 本题考查宾语从句引导词的选用。选择名词性从句的引导词可采用从句中“缺什么成分补什么成分”的原则，效果非常好。就本题来看，宾语从句中不缺少主语和宾语，可排除what和who，根据语境“Mary写了一篇关于那支队伍为什么没能赢得这场比赛的文章”可知，宾语从句中缺少原因状语，如果选择that引导宾语从句，句子也能成立，但是意思只是“Mary就那支队伍没能赢得比赛写了一篇文章”，显然不如选A更符合逻辑。答案为A。

22． No one helped me. I did it all _________myself.

　A． for　　　　　　　　　　 B． by　

　C． from　　　　　　　　　 D． to

　[解析] 本题考查介词的搭配。根据前后两句的语境，“没有人帮助我，我是完全靠自己做的。”by oneself意思是“单独地，独自地，独立地”，如：carry out the task by oneself独立地完成一项任务；become a millionaire by oneself通过自己的努力成为一名百万富翁。其他介词搭配与语境不符。答案为B。

21． -Can I speak to Mr. Wang, please ?

　　　　 -　 _______　　

　　　 A． Who are you ?　　　　　　 B． I’m Wang .

　　　 C． Speaking．　　　　　　　 D． Are you John ?

　[解析] 本题考查打电话时的交际用语。注意英语与汉语在打电话时表达习惯的不同：汉语打电话时说“我是……”，英语中不用 “I am…”，而用“This is …speaking.”或其他省略形式，如“Speaking.” “This is ….” “John speaking.” “John’s here.”等。如果要问对方是谁，英语中不用“Who are you?”，而用“Who is calling/speaking, please?” “Who’s that speaking/calling?” “Who is it?” “Is that…?”等表达形式。根据本题打电话的情景可知，答案为C。

The answer to “Is it good using mobile phone for students?” is “No” for the following reasons: Firstly, it adds to the students’ burden in finance together with its side effects, such as their not paying attention to their teacher’s teaching in class by sending messages to others. It may lead to students’ showing off themselves by owning nice and expensive mobile phones. Some students make a call with their mobile phones in the classroom, which stops the other classmates from fixing on their study. So I don’t think it good for students to use mobile phone at school.

　　　 I think it’s not wrong to follow the fashion, but the most important thing is to use the mobile phone in a right way.

　　　 Dear Henry,

As a student, I must try to learn English well and try to do something for the Olympic Games.
