21. ―Have you finished reading Jane Eyre?
―No, I ________ my homework all day yesterday. (2010全国卷I)
A. was doing B. would do C. had done D. do
【答案】A。
【考点】考查动词时态的用法。
【解析】根据句中的all day和yesterday可知，句子应用过去进行时。又如：“Have you finished your homework, Mary?” “No, I was helping my mother in the kitchen all day yesterday.” “你的作业做完了吗，玛丽?”“没有，我昨天一整天都在厨房帮妈妈干活来着。”
22. The workers ________ the glasses and marked on each box “This Side UP”. (2010全国卷I)
A. carried B. delivered C. pressed D. packed
【答案】D。
【考点】考查特定语境中动词的用法。
【解析】对于考查特定语境中词语用法的考题，最好的方法是代入翻译法，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：carry意为“搬”“扛”，deliver意为“投递”“给予”，press意为“压迫”“压”，pack意为“将……装入箱（盒等）”。根据句中的on each box “This Side Up”可知，选D最合适。
23. I’ll spend half of my holiday practicing English and ________ half learning drawing. (2010全国卷I)
A. another B. the other C. other’s D. other
【答案】B。
【考点】考查不定代词的用法。
【解析】由于说话者是将整个假期分为两个half，一半用于练习英语，另一半用于学习绘画。所以，表示“另一半”时用the other half。又如：Half of us are free on Tuesdays, and the other half on Thursdays. 我们一半人在周二休假，另一半人在周四休假。
24. As a child, Jack studied in a village school, ________ is named after his grandfather. (2010全国卷I)
A. which B. where C. what D. that
【答案】A。
【考点】考查定语从句的用法。
【解析】which引导非限制性定语从句，先行词为school，同时which在定语从句中用作主语。又如：The 8:15 train, which is usually very punctual, was late today. 8点15分的列车通常是正点的，今天晚点了。
25. Mary made coffee ________ her guests were finishing their meal. (2010全国卷I)
A. so that B. although C. while D. as if
【答案】C。
【考点】考查状语从句的用法。
【解析】比较四个选项，只有填while句子意思最通顺。句意为：趁客人用餐时，玛丽煮了一些咖啡。又如：I paused the videotape while I answered the phone. 我接电话时暂停了录像带的播放。He asked me to save him a place while he parked the car. 他去停车的时候让我给他排个队。
26. I have seldom seen my mother ________ pleased with my progress as she is now. (2010全国卷I)
A. so B. very C. too D. rather
【答案】A。
【考点】考查as…as…结构的用法。
【解析】考查as…as…结构，其意为“与……一样”，由于句中用了否定词seldom，所以第一个as也可换成so。又如：She hasn’t been quite so unlucky as she pretends. 她并不很像她所装做的那样倒运。I have never seen so beautiful a place as Cuilin is. 我从来没有见过像桂林这样美丽的地方。
27. Mrs. White showed her students some old maps ________ from the library. (2010全国卷I)
A. to borrow B. to be borrowed C. borrowed D. borrowing
【答案】C。
【考点】考查非谓语动词的用法。
【解析】因maps与borrow之间为被动关系，故可排除表示主动意义的A和D；再根据句意，地图是“已经”借来了，而不是“将要”借来，所以选过去分词（即表被动又表完成），而不能选不定式的被动式（虽然表被动但同时表示动作尚未发生）。又如：Most of the suggestions made at the meeting were not very practical. 会上提出的建议很多行不通。
28. When you are home, give a call to let me know you ________ safely. (2010全国卷I)
A. are arriving B. have arrived C. had arrived D. will arrive
【答案】B(http://www.yygrammar.com/)。
【考点】考查动词时态的用法。
【解析】根据句子本身已有的时态可知，过去完成时had arrived不能选；再根据常识，说话人应该是叫对方“已经”到家后才打电话报平安，故选现在完成时。
29. Just be patient. You ________ expect the world to change so soon. (2010全国卷I)
A. can’t B. needn’t C. may not D. will not
【答案】A。
【考点】考查情态动词的用法。
【解析】比较四个选项：can’t意为“不能”，needn’t意为“不必”，may not意为“不准”“可能不”，will not意为“将不”“不愿”。显然只有can’t的意思最符合句子语境。
30. The little boy won’t go to sleep ________ his mother tells him a story. (2010全国卷I)
A. or B. unless C. but D. whether
【答案】B。
【考点】考查状语从句的用法。
【解析】比较空格前后的句子意思：前面说“小男孩不会入睡”，后面又说“他的母亲给他讲故事”，根据常识，空格处填unless（除非）最合适。又如：She hasn’t got any hobbies unless you call watching TV a hobby. 她没有任何嗜好，除非把看电视也算作嗜好的话。
31. 一Everybody is going to climb the mountain. Can I go too, mum?
―________ Wait till you are old enough, dear. (2010全国卷I)
A. Will you? B. Why not? C. I hope so. D. I’m afraid not.
【答案】D。
【考点】考查交际口语的用法。
【解析】根据空格后的Wait till you are old enough（等你够大些再去）可知，母亲不同意让孩子去爬山，所以选D。
32. The discovery of gold in
A. is made B. would make C. was to be made D. had made
【答案】C。
【考点】考查动词的时态和语态。
【解析】英语中有个习语是make a fortune（发财，赚大钱），也就是说a fortune是动词make的宾语。从本句来看，a fortune与要填的make应为被动关系，故只能选A或C；再根据句子中led的时态可知，答案要选C而不是A。
33. We haven’t discussed yet ________ we are going to place our new furniture. (2010全国卷I)
A. that B. which C. what D. where
【答案】D。
【考点】考查宾语从句的用法。
【解析】由于宾语从句we are going to place our new furniture的结构是完整的，不缺主语或宾语等，听以不能选用作主语或宾语的which或what；而从句意来看，选D比选A更使句子意思通顺。
34. With Father’s Day around the corner, I have taken some money out of the bank ________ presents for my dad. (2010全国卷I)
A. buy B. to buy C. buying D. to have bought
【答案】B。

【解析】不定式短语to buy presents for my dad在此表示目的。又如：He will go to the clinic tomorrow to be examined by the doctor. 他明天去诊所让大夫检查。
