题解：
1. AFor these children to develop to their full adult potential在句中做目的状语，these children 是to develop 的逻辑主语，这种主谓关系在目的状语中一般是不能用分词表示的。B中不定式被动式与句意相悖；for不是连词，故不能选D，否则语句不通。
2. Cas well as 在语法功能上相当于介词，所以在句中要接动名词leading to。
3. C句子的主语为solar power or fission power，谓语是may give, collected by satellite circling the earth是后置定语修饰solar power，其中circling the earth 又是现在分词短语修饰satellite，“环绕地球的卫星”，相当于the satellite which circles the earth。其他选择项均不符合句子语法结构要求。
4. C句中已给出频次状语several times，说明要用完成时态，同时句子的时态定位是现在时they are wakened，显然不能用过去完成时，所以选C。
5. C这是一个so…that结构表示结果状语的句型， A、D 可以排除。在that从句中又有条件从句，而且应该是虚拟语气结构，B中没有表示条件的连词，是错误的。C虽然也没有连词if，但采用了倒装结构，可以将if省略，又是had done，表示与过去事实相反的假设，时态、结构完全正确，因此是惟一正确的选择。
6. D这是一个含蓄虚拟句，意为“有些妇女完全可以不呆在家里，干一份工作挣得可观的工资，可是她们决定不工作，为的是照顾家庭”，所以选D。should have made意思是“本应该做而实际上没做”，与原句意不够贴切。
7. B相当于A light with no more power than the power that is produced by…。that代替power，表示相比较的事物，而D中没有比较对象，故不对；as表示原级比较，不与than用在一起，故A也不正确；C中缺少that的先行词，也是错误的。
8. Clet alone，“更不用说……”，在用法上相当于并列连词，因此要求填入与前面一样的结构，此处是不定式。
9. D句子要求填一个能够代替these refrigerators 的代词，故排除A、C。the others一般与另一部分相对而言，在此句中不对，所以选the ones。
10. A句子后半句是倒装句，主语是复数its soil and the water of its lakes, rivers and oceans，因为较长，所以后置，故选A。
11. C此句含有让步状语从句whether…or…“不管是……还是……”，采用倒装后省略连词，用原形动词，所以只能选C。
12. Cwhen引导时间从句：“纳粹上台的时候,他被赶出德国……”then不是连词, 用在句中不符合句法要求; 如果选B, 应为and then; before填入句中句意不通。
13. D句中要求一个能够引导of介词宾语从句的连接词, 所以只有what具有这个功能。
14. A前后两个句子是对比关系: increased和barely growing, 而even if表示让步“即使”; after表示时间;now that表示原因, 故只有whereas正确。
15. Cthough 表示让步, 意为“虽然”，全句的意思是: “他的长相挺好, 身体虽然瘦小, 但有点儿运动员的样子。”somehow“不知怎么”、“不知什么原因”。as 可以引导让步从句,但句子结构要倒装, 不用于省略句, 因此在此处不合适。somewhat“有几分”、“有点儿”, 没有让步意味。
16. D句子讲的是 “人们期待到21世纪前10年时,国际性商业航空交通远远超过当今水平”, 人们现在就期待, 而不是将来期待, 所以A、B是错误的; 另外, 表示到将来某一时刻为止已经完成的动作或出现的状态, 应用将来完成时, 按句意, 是指extend这一动作的完成, 所以应该在不定式上体现出来。根据上述分析, 选D符合句意要求。
17. C动词advocate后接动名词而不接不定式做宾语。D虽然是动名词, 但用其完成式在语义上讲不通。
18. Apulling是现在分词在句中做horses的定语, 相当于which pull。
19. Chad been left表示与过去事实相反的假设 “如果情况还像以前那样”。
20. A不定式to find out做结果状语,有意想不到的含义。不定式表示结果时, 用其一般式即可。
21. Bno less than “与……同样(重要)”。全句意为: “放松休息, 就像新鲜空气、纯净水、清洁的食品一样, 是健康的身心所不可缺少的。”
22. Bto have a large fortune与to do well a bit of work…是并列不定式。另外，worth, worthy, worthwhile在用法上的区别是:(1)worth是介词, 后接动名词或名词，形成介词短语。接动名词时, 与主语是动宾关系，其形式是主动的，意义是被动的。如: The book is worth reading. (2)worthy是形容词, 置于be动词后或名词后面, 做后位修饰语, 其结构是: be worthy of doing sth., sth. is worthy to be done。(3)worthwhile是形容词，要与形式主语it并用：It is worthwhile to read the book.worth和worthy都不能用于这种结构。
23. Aone 指代前面提到的具有泛指含义的可数名词单数, 在该句中指代another nation, 句中属于泛指，可见B是错误的。such指代前面讲过的整个情况，多用作主语。that 指物时常用来指代不可数名词, 指代可数名词时具有特指含义。
24. Bwhether 引导名词性从句做主语, 谓语动词应为单数。另外，remain一般不用被动式, 所以B为正确选项。
25. C这是there be句型的异化形式，即there be 句型中还可以用be以外的不及物动词，如live, stand, exist, come, remain等。
26. B要填入的成分在从句中做状语, 据此排除A、D。另外，respect要求介词in, 相当于in this respect “在这方面”, 故选in which。
27. D全句用的是一般现在时态, 说明一种情况, go 是非及物动词, 要填入的是with介词短语的一部分，应用动名词形式, 所以选going up。
28. Bthat引导宾语从句, see在句中的意思是understand。此句切不可从汉语角度理解成 “我怎么错了”或 “我为什么错了” 而错选了A或D。
29. Bwhich have many advantages是非限定性定语从句，在此有让步的含义。
30. C句子用的是过去时态…were glad…, 不定式完成式to have stayed表示这一动作发生在谓语动词were glad之前, 相当于：The members of the delegation were glad that they had stayed longer than originally planned.
31. C句中不定式表示原因: “学生有机会用英语与美国人交谈，很受鼓舞。” 所以应用不定式完成式。如果句子用的是一般现在时are, 那么选A是对的。
32. Atolerate要求动名词做宾语, 只能选A。
33. C动名词being 做students 的逻辑谓语, 相当于…students… being unable to understand what they read。整个动名词短语做of的宾语，所以只能选C。
34. D这是一个含蓄虚拟条件句，前半部分假设，后半部分真实，因此应选could have caught，意为“我本来能赶上火车的，可是那天早上我睡过头了”。区别这类含蓄虚拟条件句的关键词是but。
35. Ddidnt have to do it“不用非得洗(碗)”，符合句意。
36. Bnot…any more than…“与……同样不……”。本句意为：“摄入的维生素超过了身体所需要的量并不能使身体更好地发挥作用, 就像往油灯中倒入过多的油不能使其更亮一样。” no more…than 与not…any more than同义, 但句中前半部分已有not, 此处再填no是错误的。
37. B此题测试的是平行结构问题, 即在并列或比较结构中，并列或比较的成分在语法形式上应一致。 如该句中应为：He spends as much time idling about as he spends (much) time studying.句中does 代替spends, idling与studying平行。
38. Cthe one 代替带定冠词的单数可数名词。句中代替the student，故选C。
39. D句子用的是just as…so…句型，后半部分要求倒装，所以应选D。
40. Cwhere引导定语从句，在从句中做地点状语，相当于from the top floor。
41. Dwhoever引导名词性从句，并在从句中做主语，用来指人。they thought 是插入成分。
42. Cin that“是因为”，引导原因状语从句，符合句意。by which表示手段；so that引导目的状语从句；provided that引导条件状语从句。
43. Amade to do so是it is made to do so 的省略形式。unless是连词，应连接句子，所以除A以外的其他几个选项都是错误的。
44. B此处用过去完成时，是因为本句意指“到那次敲门，已经是第三次有人打搅我了”。句中用词was和that evening都说明指过去发生的事，到过去某一时刻为止已出现的情况用过去完成时。
45. Awhich在句中是关系代词，要引导一个句子，而B、C、D三个选项中都没有谓语，因此不是句子。本句意为：“政府同意提供服务设施，经费由居民在十年期间偿还。”
46. Bthere being 做介词of 的宾语，如果是介词for，则用there to be。
47. C分词短语做伴随状语，形容词open在分词短语中做补语，表示状态，不用过去分词，所以D不正确。
48. B此句是含蓄虚拟语气句，暗含的假设条件为：if they hadn’t happened to be short of hands。故应选B。
49. Cmay have done“(不管我们白天)可能做了些什么”，符合句意。should have done“本该做(但实际未做)”；would have done表示与过去相反的假设；must have done是对已发生的情况作肯定推测。
50. A句中too late相当于too late to catch the train，所以选其他词不合适。
51. Crather than 表示对比，在意思上前后形成对照：take advantage of your generosity…rather than become appreciative of your kindness意为“利用你的慷慨，而不是理解你的好意”。另外，rather than在结构上起并列作用，使take advantage与become appreciative平行。
52. Cthe one替代the age，还原为：…but must write for the age in which he lives and the ages which are to follow。
53. Bin which在定语从句中做状语，相当于in the balance of nature (many square miles of…)。
54. Cthat引导case的同位语从句，其他连接词都不合适。
55. Bfor连接一个原因分句，对前面的推测做原因上的解释。请考生记住：无论从逻辑推理还是从语法规则上看，只要前面是表示推测的句子，后面大都用for连接后一句，而不用其他连词。
56. D时间状语thus far“到目前为止”，与现在完成时连用，据此排除B、C。比较从句完整的结构应该是…than the thought which has been given thus far，可以把than 看做关系代词在从句中做主语，也可以把主语看做是省略了。
57. A题句由于主语较长，采用了倒装结构，可还原为：the nation-wide movement to support the Kampuchean people in their heroic struggle against the aggression of the Vietnamese is of great significance。movement要求不定式做定语，其他选项均不符合语法规则。
58. Alooking for…分词短语做came的伴随状语，如果选to look for做目的状语的话，不该有逗号。
59. B动词request要求其主语从句、宾语从句或同位语从句中谓语动词用(should+)原形表示虚拟。该句中that引导的是主语从句。
60. Dcant have done 表示对已发生的情况作否定推测“一定不是/没……”，根据句意只能选D。
61. Dno more…than…“不比……更……”。此句意为：“研究表明，喝了酒但不过量的司机可能出车祸，不喝酒的司机也同样可能出车祸。”
62. Drather than起并列作用，使merciful与criminal形成平行结构，表示对比。
63. Anone but相当于no one but“只有”，通常接表示人的词；nothing but接表示物的词；none other than和no other than两者的意思都是“(不是别的)……正是……”，与本题全句意思不符。
64. Aas在句中是关系代词，引导非限定性定语从句，其先行词是precautions，其他几个选项都不是关系代词，所以是错误的。
65. Dwhat是关系代词，引导名词性从句，同时又在从句中充当一个成分，如在本句中做从句的主语，整个名词性从句做介词of的宾语；which只能引导形容词性从句；that引导名词性从句时，只是连词；whatever用在句中不通。
66. Cunless“除非”，从主从句的逻辑关系上看是惟一正确选择。句意：“假如发生了水灾或地震，且火车、汽车又无法通至灾区，除非用飞机空投，否则那里的人们就会饿死。”
67. Bto become在句中做desire的定语，意为“成为一个著名作家的愿望”，其他结构一般不做desire的定语。
68. B不定式to have been working…做主语scientist的补足语，用完成进行式表示：“这个科学家已对如此复杂的问题研究了大约十年，并且还要继续研究下去。”
69. Dtaken在句中做后置定语，修饰majority, 由于与所修饰的词是动宾关系，所以应用过去分词，a majority which is taken collectively可以理解为“(把)大多数人作为一个整体”。
70. A句中but表示转折，后面陈述的是事实情况：“……看错了问题所以没答对”。暗指“若不是看错了题，就会答对而且通过考试”。因此句子前半部分用的是虚拟语气would have passed。
71. Cneedn’t have done sth.表示做了不必做的事，此句意为：“你真不必写这么长的文章，老师告诉我们只写200个词，可你写了300个词。”
72. AB、C选项之所以错，主要是由于long的位置不对，应为：B. Being long used…；C Having long been used…。句子前半部分是状语，故D也不对。由此可见A是惟一正确的选择。
73. Cother than 的意思相当于except，常用在否定词之后，如nobody other than…，nothing other than等。本句中与no在一起连用，意为“只有在英国……”。it has been said是插入语。
74. Bas是关系代词，引导非限定性定语从句， 其先行词是measures，相当于…as the measures which are taken by the government…，其他几个词都是连词，不能引导定语从句。
75. A句中的第一个空白处需要一个引导名词性从句的关系代词，在从句中做write 的宾语；第二个空白处要填一个修饰way的定语从句的关系代词，因此只能选A。注意: 先行词是way, 引导定语从句的关系代词一定不能用how, 可以用in which, 可以用that, 也可以省略不用。
76. Abefore应该理解成“(几百年过去了,人们) 才……”; 如果用after应该是…after centuries passed they took note of the fact…; 如果用until, 应该是they didn’t take note of the fact that…until centuries passed。
77. B此句意为：“他明天去巴黎,加上这次, 他就去了二十次了。”根据句意,应用将来完成时态。句中有back一词, 故D不合适。
78. Bto use…, 不定式短语做way的定语, 只是因为定语太长,故将谓语前移,使句子避免头重脚轻。by using表示方式, 做状语用; using为动名词, 不能做way 的定语, way要求不定式做定语; used, 无论从语法结构上还是从意义上都讲不通。
79. A分词短语做伴随状语, my footsteps与echo的关系是主动的,因此用现在分词。另外, 分词做伴随状语表示与谓语动词的动作同时发生, 所以用其一般式。
80. A本句意为:“除了个人喜好外, 社会环境也会直接或间接地影响你使用的媒体和媒体的内容。例如, 家庭的其他成员常常选择的媒体内容你就未必选, 可是你也得使用。”句中暗含了 “如果是你, 你就不会选” 的意思, 所以用虚拟语气合适。should not have selected表示“本不应该选”; must not select表示“一定不要选”; cannot have selected表示“一定不能选”, 过于绝对。只有would not have selected 符合句意。
