32. The old gentleman never fails to help_____ is in need of his help. 
A. whom                        B. who 
C. whoever                      D. whomever
答案：C 宾语从句的引导词。这里所用的词应该既作help的宾语又作后一句子的主语，同时又表示任意性，而句子本身强调的是后一种身份，应该用whoever，选C。

33. ______ under a microscope, a fresh snowflake has a delicate six-pointed shape. 
A. Seeing                       B. Seen 
C. To see                        D. To be seen
答案：B 分词。句子中间的分号就提醒我们应该用分号，首先排除C和D项；根据句意应该是用过去分词，表被动关系，所以应该选B。 

34. “When are you going to visit your uncle in Chicago?” 
   “As soon as_____ our work for tomorrow.” 
A. we’re complete                B. we’d complete 
C. we’ll complete                 D. we complete
答案：D 时态。据题干，应该是将来时；但是as soon as…引导的从今通常用一般现在时表示将来时，所以选D。 

35. Neither John nor I _____ able to persuade Richard’s grandfather to attend the wedding. 
A. am        B. are            C. are to be       D. is
答案：A 主谓一致。Neither…nor…的谓语是就近一致原则，就是谓语跟距离最近的那个主语相一致。据题意应选A。 

36. You ought _____ the matter to the manager the day before yesterday. 
A. to report                      B. to have reported 
C. to reporting                    D. have reported
答案：B 时态。Ought to do sth.是固定用法，先排除C和D项，同时根据时间副词the day before yesterday，可以得知动作发生在过去的过去，应该用过去完成时，选B。

37. We look forward to _____ to the opening ceremony. 
A. invite                         B. be invited 
C. having been invited              D. being invited
答案：D 固定搭配。Look forward to doing sth.，根据这个固定搭配可以排除A和B项，而本句的动词Look用的是现在时，所以用完成时不正确，又可以排除C项；显然D为正确答案。
