答案：
1—10BCDBABADCB 11—20BAABCBDCAC 21—30ABCDBDACAC
31—40CAABDADBDC 41—50DDBDAAABCD 51—60ADCDCACCAA
解析：
1. 破除prevent…from doing…的思维定势，带逻辑主语的不定式作目的状语。这句话的意思是：为了我们美好的生活，必须采取措施制止污染。
2. 本句不是考查can’t help doing something的结构，help的后面也可以跟不定式，解释为：帮助做。
3. 不能把这句话错误地判断为强调结构，是where引导的限制性定语从句。
4. 这个对话的后半部分容易错误地理解为：注意雪的信息以防止一场雪灾。其实，不是这样，snow disater的前面有了定冠词the，就说明和前面的内容是并列的和已知的。
5. 该句容易被错误地判为介词加关系代词引导定语从句的结构。around也作定语，因为简洁，被放在先行词和定语从句之间。买书应该在书店买，不能到书店周围买。
6. 对含有turn的短语动词考察，这类题目很容易犯错。经过分析，turn out的意思符合句子的要求。turn up: 到场、出现、把音响声音调大；turn out: 结果证明、生产；turn over: 揭开、翻滚；turn down: 拒绝、把音响声音调小。
7. 本题考查比较级在语境中的运用。for在这里是“就……而言”的意思，而第二个选项要抓住信息词still在此处的妙用，它是用来修饰比较级的，加上上文的cold，在此处就不难选择了。
8. 一般地说，不定代词many , little或few前是不许使用定冠词的，但是如果它们修饰的名词有特指或限定意义时，它们前面就应使用定冠词了。这句话的意思是：我们必须充分利用敌人的内部矛盾，争取多数，反对少数。
9. whatever具备两个意思，其一是no matter what , 引导让步状语从句；其二是anything that , 引导名词性从句，在本题中，Whatever 引导的是一个宾语从句，whatever在这个宾语从句被用作主语。
10.本题考查在语境中灵活运用、辨析短语用法的能力，此处seldom，if ever是一个短语，是“从不，决不”的意思。
11. 后半句的第一个it会影响正确的选择，where引导的表语从句中的it就是指丢掉的MP3，指代上文的事物，用it。
12. but 前面的do不是行为动词，是助动词，but后面的不定式中的to不能省略。比较下面的句子：He could do nothing but wait for the general manager to come back.
13. 英语中有It is said that…等结构，没有It is told that…和It is spoken that…的结构，但是有I am/was told that…的结构。该句考查“形式主语+be+形容词+that从句”的结构，又主语
是it，而不是表示的人。答案应该为certain。
14. 这是对强调句进行的特殊提问，尽管提问的部分是人，为了避免和前面的who重复，答案应该选that。
15. 汉语中有明亮如日、明亮如月、明亮如星星的说法，但英语却说as bright as day。这是固定的习语，day是白昼的意思。
16. at all用在条件句中，意思为“如果当真”。该句话的意思是：如果这种药真能治什么病的话，它当然能治心脏病。
17. say sorry to somebody为“向某人道歉”的意思；apology 构成make an apology to somebody 的结构；excuse则为excuse me for something/doing something结构；pardon常构成pardon me for something或I beg your pardon的结构。
18. 家庭作业还没有做，并且是主语I做，答案为to do。比较下面一句话：I will go to Beijing. By the way, do you have something to be taken to Beijing?
19. begin to do something和begin doing something在意义上是一样的，但begin用了进行时，后面就宜用不定式。
20. 前文的意思暗示后半句的意思应该是这样的：你怎么赞扬她都不嫌过分。cannot...too... 总不嫌过分；越...越好，是常见的用法。
21. 步行10分钟的路程有两种表示法：ten minutes’ walk或a ten-minute walk。答案为A。
22. fall和drop都有从高处往下落，但fall是不及物动词。sink是下沉，尤指在水中下沉。dive: 跳水、飞奔。这句话是描写伽利略所做的比萨斜塔实验。
23. no sooner... than... ，一 ... 就... 。该句话的意思是：我们一到达那儿，就开始下雨了。no sooner和than搭配；hardly和when搭配，意思一样，都仅用于过去，很容易犯错。24. “There be…”是一个完整的主谓结构，but gave help to the persons stuck in the snow…是修饰person的定语从句；也就是说but用作关系代词，在定语从句中作主语。这种用法在地道的英语中是常见的。but这样使用时，是有一定限制的，通常必须用在某些否定意义的词语后面，意思相当于“that…not, which…not或who…not…”。其意思等于“没有……不……”，可以指人，也可以指物。这句话的意思是：一月下旬，在湖南郴州，人人都给予被困在雪中的人以帮助。
25.含有否定词但不表示否定的结构之一：否定结构+ 含有否定意义的前（后）缀词。句子的意思为：你要三思而行，应该小心后果。
26. 数字电视和卫星电视有时间的早晚，图象和过去比更清楚，答案为D。
27. 句子长，先行词side又被介词短语of the head隔开，容易对句子结构的分析产生错误。表示放手机的位置，答案为A。
28. 状语从句为“从属连词+主语it+is(was)+形容词”的结构时，常简化为：“从属连词+形容词”的结构。
29. apple of one’s eye为固定短语，“掌上明珠，珍爱的人或物”的意思。
30. grab是用满有把握的动作抓住某物。在题目中，接力赛的运动员抓接力棒，当然是有把握并且动作很快的。再看下面的例子：He jumped up, grabbed his hat and ran to the bus stop. 他跳了起来，抓住帽子，向汽车站跑去。grasp表示牢牢地抓住、掌握、把握的意思。seize是“抓住、夺取”的意思，表示突然抓住、占领，不使逃脱。snatch是“抢取、攫取、抓住”的意思，表示以迅速的拉扯动作作出其不意的抓取，它是一个贬义词。
31. 这段文字告诉我们：现金是第一代货币；支票是第二代货币；电子货币就是第三代货币，也就是我们讲的无货币时代。后半句是前半句的补充，两个句子之间用逗号隔开；后面的部分用独立主格结构，不能用完整的主谓结构。
32. ever与现在完成时连用时，常用在疑问句中，常解释为“曾，曾经”，常用句型：Have you ever…? 有时也用在肯定的陈述句中起强调作用。just与现在完成时连用时，表示刚过去的动作。already与现在完成时连用时，表示动作距离现在不远的时间已经完成，用在肯定句
中；yet刚好和already相反。这句话的意思是：那是我见过的最大的鱼。
33. 此题的时间状语before I joined them是很好的参照。第一个空应该用过去完成进行时，第二个空根据时间now用现在进行时。
34. 此题中包含一个定语从句，the person作句子的主语，要填入的应该是句子的谓语，根据后面的时间状语为the day after tomorrow，应选将来时。句中的定语从句we referred to中的to不影响主句的谓语，故应选B。
35. 此题是独立主格结构，如果题目改为It would be a good idea to use a plastic bottle, _______ is cut off, as a container to grow young plants in. 答案则为A或C。容易把答案搞错。
36. 此题很容易误选B，认为第一次提到girl用不定冠词，第二次提到就应该用定冠词。但是，句中第二次提到girl时并不是特指的，此句实为一省略句，补充完整是：… and she is a girl everyone likes to study with.
37. 此题选D，为He asked me whether I would be sent to work in Hangzhou.之省略。
38. 考查be popular with somebody的固定短语，容易把介词搞错。
39. 此题最佳答案为D，可视为No, she isn’t. But she was a dancing teacher.之省略，即其意为“她现在不是舞蹈教师，但她过去是”。上半句中是否定形式，给正确理解yes和no带来困难，容易出错误。
40.此题句型为have sth done, she had had repaired为定语从句，修饰the dish washer。迷惑选项为B项。had had repaired放在一起，其实是正确的，有一定的误导作用，容易让答题者不肯定这个答案。
41. 这道题不是文字游戏的游戏。虽简单，容易错，尤其是at叠在一起，增加对正确答案的怀疑。
42. but usually once a week是答题的关键，只能看具体情况定了。
43. 句末的the other day意为“前几天”，所以句子应用过去时态。此句有两个难点：一是句中插有however一词，分散了同学们的注意力；二是所填选项B为许多同学所不熟悉的强调用法。
44. 他的伤没有好，说明过去没有认真听医者的话，不是现在的情况。答案的B有迷惑性。
45. 在某些特殊语境中，疑问词出现在句中甚至句末是完全可能的,但这多半是因为有特殊的语境或使用的句式比较特殊。这句话的意思为：它们看起来一模一样,我实在分不清哪个是哪个。
46. will除了用作表示将来时的助动词外，还可用来强调愿意或不愿意，是情态动词的用法，吸烟当然靠自己的愿望。
47. 前半部分作为定语从句，用that或which都对；但是，后面的强调结构就只能使用that 了。很显然，避免重服，答案只能是A。
48.在这个句子中it是形式宾语，如果这样的句子中，无论是主语从句，还是宾语从句，出现了any good , no good , any use 或no use，就该使用动名词来作句中真正的主语或宾语。
49. 英语中用来补充前面的内容，用现在分词作结果状语。
50. 这是一个关于must的用法的简单考查，后半句其实是以下的结构：Must I do as you tell me? I must. 答案的mustn’t I有迷惑性，反意问句的前面必须是完整的句子。
51. 考查的spend time (in) doing sth的结构，spend的后面的宾语增加了干扰项。比较：He did what he could to learn Japanese.
52. 容易错选答案的A，that引导的同位语从句中含有if引导的状语从句。
53. 水感觉上去凉爽，中文里有被动的含义，英语中没有。
54. that引导的同位语作suggestion的同位语，表示建议、要求，用虚拟语气，动词形式为：(should)+动词原形。
55. as well as, including, together, besides, along with等介词短语并列主语，谓语动词遵守就远不就近的原则；也就是说，不对前面的主语产生影响。
56. 英语中，承前文常采取省略的原则。这里保留不定式的标记to。
57. 由于Not only 置于句首，故用部分倒装结构。第一个has助动词，是句中谓语动词has been sold中has的提前。第二个has为实义动词，定语从句中表示“有”的意思。本句的意思为：不但是她所有的珠宝而且还有她的房子一起已经被卖掉作为她丈夫的赌债了。
58. 现在分词短语hoping to catch the bus用做伴随状语，即一边跑一边希望能赶上汽车。容易错选B，将to hope to catch the bus视为目的状语。因为“他拼命地跑”目的是“为了赶上公共汽车”，而不是“为了希望赶上公共汽车”，换句话说，将“希望”作为“目的”不妥。
59. 看了题目后，也许会毫不犹豫地认为此题应选B，理由是none前没有并列连词and 或but，但错了。此题的最佳选项应为A，注意此句的translated 不是谓语，而是一个非谓语动词（过去分词），所以逗号后面其实不是一个完整的句子，而是一个独立结构。假若在translated 前加一个助动词was，则此题应选which，构成一个非限制性定语从句。做这类题要特别小心，不要受思维定势的影响。
60. 这是对“情态动词+ have done something”结构的考查，根据后半部分的意思推断：李平昨天本来不必给我打电话，答案应该是needn’t。shouldn’t have done, 本不该做；couldn’t have done,本不会做、过去绝不会做；wouldn’t have done, 本不会做。
