21. Every evening after dinner, if not ________ from work, I will spend some time walking my dog. (2009湖南卷)
A. being tired B. tiring C. tired D. to be tired
【答案】C。
【考点】考查省略句的用法。
【解析】此题从四个选项来看是考查非谓语动词的用法，但本质上是考查省略结构，句中的if not tired from work为if I’m not tired from work（如果我下班回来不是很累的话），其中的tired已转化为形容词。
22. Most Americans would prefer to keep their problems ________ themselves, and solve their problems ________ themselves. (2009湖南卷)
A. to; by B. by; to C. for; to D. in; on
【答案】A。
【考点】考查介词在固定搭配中的用法。
【解析】第一空填介词to，因为keep sth to oneself为英语中的固定搭配，其意为“不把某事告诉别人”，又如：I’d be grateful if you kept this information to yourself. 这事你若能保密则不胜感激。第二空填介词by，因为by oneself为固定搭配，意思“独自”，solve sth by oneself意为“靠自己解决”，又如：I’ve tried to solve the problem by myself, but it defeats me! 这个问题我想自己解决，但把我难倒了!
23. When he ________ the door, he found his keys were nowhere. (2009湖南卷)
A. would open B. opened C. had opened D. was to open
【答案】D。
【考点】考查be to do sth结构的用法。
【解析】be to do sth可以表示计划或意图，根据后面一句的时态found，空格处应用一般was to do sth。句意为：他要开门时，发现钥匙不见了。又如：He was to say something more, and then checked himself. 他还想说几句的，却又止住了。这样的用法也可换成be about to do sth，如：I was about to go to bed when the telephone rang. 我正要睡觉，忽然电话响了。
24. I can ________ be a teacher. I’m not a very patient person. (2009湖南卷)
A. seldom B. ever C. never D. always
【答案】C。
【考点】考查特定语境中副词的用法。
【解析】做这类考题的最好方法是代入翻译法，即将四个选项分别代入句中再翻译原句，哪个选项使原句最通顺，哪个选项就是最佳答案。四个选项的意思分别为：seldom意为“很少”；ever用于肯定句中意为“永远”；never意为“绝不，永远不”，always 意为“总是”。根据句意，只有C最佳。句意为：我不可能成为一名教师，因为我不是一个很有耐心的人。
25. At the age of 29, Dave was a worker, ________ in a small apartment near
A. living; wondering B. lived; wondering
C. lived; wondered D. living; wondered
【答案】A。
【考点】考查非谓语动词的用法。
【解析】空均填现在分词，用作定语修饰a worker。注意句中的并列连词and，用于连接两个相同的句子结构（即连接两个现在分词短语）。句意为：戴夫29岁时是一名工人，住在波士顿附近的一间小公寓，不知未来怎么办。
26. I was born in
A. which B. of which C. that D. whose
【答案】D。
【考点】考查定语从句的用法。
【解析】在所给定的四个关系代词中，只有which和whose能用于名词作定语，故可排除B和C。而关系代词which和whose用于名词前作定语的区别是：which具有that或this的语义特征，而whose则具有one’s的语义特征。比较：It was an island whose name I have forgotten. 这是一座岛，名字我忘了。My father may have to go into hospital, in which case won’t be going on holiday. 我父亲可能需要住院，如果那样他就不去度假了。
27. Would you please keep silent? The weather report ________ and I want to listen. (2009湖南卷)
A. is broadcast B. is being broadcast
C. has been broadcast D. had been broadcast
【解析】B。根据句中的“你能安静点吗”可推知，此刻天气预报要么就要播出，要么就是正在播出，所以答案选B。

A. whichever B. however C. whatever D. whoever
【答案】C(http://www.yygrammar.com/)。
【考点】考查宾语从句的用法。
【解析】由于动词take缺宾语，所以可排除不宜用作take宾语的B和D；再根据句意可排除A。whatever在此相当于anything that。句意为：她是我们的宝贝。我们已经作好准备不惜一切代价来挽救她的生命。又如：We’ll do whatever we can to save him. 我们将尽我们所能来挽救他。
29. Nowadays people sometimes separate their waste to make it easier for it ________. (2009湖南卷)
A. reusing B. reused C. reuses D. to be reused

【解析】此题考查由介词for引出的不定式复合结构――for+宾语+不定式。类似的例子如：Can you arrange for the goods to be delivered on Monday? 你能不能安排在周一把货送到?
30. ―It’s the office! So you ________ know eating is not allowed here.
―Oh, sorry. (2009湖南卷)
A. must B. will C. may D. need
【答案】A。
【考点】考查情态动词的用法。
【解析】must在此表推测，其意为“一定”。句意为：这是办公室！你一定知道在办公室吃饭是不允许的。又如：You’ve read that book so many times, so you must know it backwards by now! 那本书你读了很多遍，所以你现在一定能倒背如流了吧!
31. Please do me a favor―________ my friend Mr. Smith to Youth Theater at 7:30 tonight. (2009湖南卷)
A. to invite B. inviting C. invite D. invited
【答案】C。
【考点】考查祈使句的用法。
【解析】本题从所给选项来看，好像是考查非谓语动词的用法，但其实是考查祈使句的用法。注意空格前的破折号，它说明其后应是一个完整的句子，故只能选C，构成祈使句。又如：Don’t miss this chance to travel―grab it before the boss changes her mind. 不要错过这次旅行的机会――趁老板还没改变主意之前，抓住这个机会。
32. You and I could hardly work together, ________? (2009湖南卷)
A. could you B. couldn’t I C. couldn’t we D. could we
【答案】D。
【考点】考查反意疑问句的用法。
【解析】由于陈述句部分的主语为you and I，所以应用we来概括，故可排除A和B；又因为陈述句部分含有半否定词hardly，故反意疑问句要用肯定式，即答案选D。
33. Either you or one of your students ________ to attend the meeting that is due tomorrow. (2009湖南卷)
A. are B. is C. have D. be
【答案】B。
【考点】考查主谓一致的用法。
【解析】当either…or…连接两个成分用作句子主语时，其后的谓语动词通常与紧挨着的那个主语保持一致，故选B。又如：Either he or you are right. 要么他对，要么你对。
34. ________ the police thought he was the most likely one, since they had no exact proof about it, they could not arrest him. (2009湖南卷)
A. Although B. As long as C. If only D. As soon as
【答案】A。
【考点】考查反意疑问句的用法。
【解析】做这类考题的最好方法是代入翻译法，即将四个选项分别代入句中再翻译原句，哪个选项使原句最通顺，哪个选项就是最佳答案。四个选项的意思分别为：although表示让步，意为“虽然”；as long as表示条件，意为“只要”，也可说成so long as；if only意为“要是……就好了”，相当于I wish；as soon as表示时间，意为“一……就”。根据句意，只有although最合适。
35. ―The food here is nice enough.
―My friend ________ me a right place. (2009湖南卷)
A. introduces B. introduced C. had introduced D. was introducing
【答案】B(http://ask.yygrammar.com/)。
【考点】考查动词时态的用法。
【解析】根据对话内容可知，此刻说话者就在其朋友介绍的那个餐馆用餐，所以其朋友给他们介绍这家餐馆肯定是在此之前，故用一般过去时，即选B。顺便说一句，这道题中的My friend introduced me a right place有两处惯用法问题：一是introduce习惯上不接双宾语；二是introduce表示“介绍”时，主要用于介绍两个不认识的互相认识，或是向听众或观众宣布并介绍演讲者或广播、节目等的细节。此句中的“介绍”其实是指“推荐”，故应用recommend，即应改为：My friend recommended me a right place.
