53. “You      borrow my notes provided you take care of them.” I told my friend.
[A]could    [B]should    [C]must    [D]can

54. If only the patient      a different treatment instead of using that antibiotics, he might still be alive now.
[A]had receive [B]received [C]should receive [D]were receiving
正确答案为A). If only引导的虚拟语气,解释为”要是…该多好啊!”. 与现在的事实相反的则if only后接过去式did,和过去事实相反的则接过去完成时had done. 这里是说要是这个病人接受了不同的方式(其实那个时候并没有接受),与过去事实相反用过去完成时. 句意: 如果那个病人不使用抗生素而是采用其他疗法,他现在可能还活着呢.
55. Linda was     the experiment a month ago, but she changed her mind at the last minute.
[A]to start        [B]to have started
[C]to be starting    [D]to have been starting
正确答案为B). be to do是固定用法. 由于start the experiment这个动作先于change her mind,所以用过去完成时be to have done表示在过去的事情对现在的影响. 注：动词不定式的完成式有时用在intended, expected, meant, were to, was to等过去式的动词后面，表示未实现的行为。例如：
1)I meant to have sent the book to you by mail. （我本想把这本书邮寄给你的。）
2)He was to have been the new ambassador, but he fell ill. (他原是要任新大使的，但是他病了。)

58. The committee has anticipated the problems that     in the road construction project.
[A]arise    [B]will arise    [C]arose    [D]have arisen

59. The student said there were a few points in the essay he

60. He would have finished his college education, but he    to quit and find a job to support his family.

61. The research requires more money than      .
[A]have been put in    [B]has been put in

than作为专四语法的重点,考试中出现很多次了.常见的考法有如下两种:
•    连词 than 引导比较状语从句，有时省去部分谓语，保留了主语和助动词，此时助动词可
以移到主语前。如：John drives much more carefully than does his father. (=than his father drives)
•    连词 than 引导比较状语从句，常省去主语，保留谓语部分，这种结构多见于正式文体中。如：Don’t eat more than is good for you.
例子：44. The indoor swimming pool seems to be a great deal more luxurious than ____. (98)
A. is necessary       B. being necessary
C. to be necessary    D. it is necessary
例子：46. There ought to be less anxiety over the perceived risk of mountain climbing than ____ in the public mind today. (99)
A. exists         B. exist        C. existing      D. to exist
62. Overpopulation poses a terrible threat to the human race. Yet it is probably    a threat to
the human race than environmental destruction.
[A]no more  [B]not more  [C]even more  [D]much more
正确答案为B). 本题是该年专四考试中语法较难的一题. not more…than的意思是与其说…倒不如说…这里意思是: 人口过多对人类的威胁还不如对环境的破坏更为严重。A选项的意思是: 人口过多跟环境破坏一样对人类构不成什么威胁。通过这道题,试比较如下两句句子:John is not better than Tom约翰不如汤姆好。  (但是两人都不错) John is no better than Tom约翰比汤姆好不了多少。  (两个人都不怎么样)
not more than有两种用法:
  1)[后接名词](=at most)作"不超过、至多"解。
  There are not more than five books in the case. 箱子里至多有五本书。
  He has learned not more than 100 words. 他学会的词不超过100个。
  2)[后接从句]往往为"han"形式,作"还比不上"解。本句型侧重点往往在后一个分
句,译成汉语时,仍按原来的语序。
  I am not more mad than you. 我哪里像你那么疯。
  This book is not more interesting than that one. 这本书不如那本书有趣。
no more than用法：
　　1)[后接名词](=only)作"不过,仅仅"解。
  He is no more than a puppet. 他不过是个傀儡。
  2)[后接从句]这种结构在不同的语言环境里有三种不同的用法及含义。
  作"没有比……更……"解,其形式往往为"no...han"。
There is no social problem it is more incumbent  义不容辞的upon us to understand than this of the role of custom.（L44, New Concept English, IV）
