一、主句单一原则任何一个句子中只可能有一个主句。做题时考生需要首先判断原题中已经给出的句子结构，如果已经有一个主句，那么就绝对不能够再出现另一个主句，除非中间有连接词进行联系。
例1：___, work songs often exhibit the song culture of a people in a fundamental form. (A) They occur where they are (B) Occuring where (C) Where they occur (D) Where do they occur 分析：空格后面是一个主句，(A)为带有从句的主句，空格后又是主句，有两个主句一定错。C为地点状语从句，正确(劳动歌曲发生的地方)。
例2: ___Indiana, is in a rich farming and dairy area, it is primarily a diversified 1 industrial center (A) Fort Wayne (B) Although Fort Wayne (C) For wayne is in (D) Fort Wayne, in 分析：空格后有两个谓语动词但中间没有连接词，由此可知，最后一句话是一个主句，空格处应该有从句引导词，四个选项中只有（B）中although能引导从句，故选（B）。
二、谓语动词专一原则任何一个句子只可能存在一个谓语动词。句子中不可能没有谓语动词，也不能多于一个谓语动词(除非中间存在连接词)。
例1：William Walker's mural, “Wall of Respect,” ___an outdoor wall in Chicago, deals with social issues. (A) covers (B) covers it (C) which covers (D) which it covers 分析：空格后的deals with 是谓语动词，A, B是谓语形式, 和deals with 之间没有连接词，可先排除; D 中的it多余，因为在定语从句中which已经作了主语；C构成正确的定语从句
例2：In copper 2 engravings and etchings, ___caused by the edges of the plate is clearly visible on the paper. (A) the impression is (B) if the impression is (C) impressions (D) the impression 分析：题目中的is是谓语，A,B中是谓语重复。C为复数名词，与后面的谓语动词is的数不一致，故也排除。因此选择D，caused.... 修饰impression
三、平行结构技巧：如果填空题中空格的后面有and, 或者and后面有空格，那么这道题目一定是考察平行结构。填空题中平行结构出现的形式是： A and B, A , B, and C
例1：The technique of recording 3, classifying, and___is known as accounting 4. (A) an enterprise's transactions summary (B) the summarizing of an enterprise's transactions (C) transactions of an enterprise are summarized (D) summarizing the transactions of an enterprise 分析：空格的后面是and, 一般考平行结构，空格处缺与前面recording、classifying并列的动名词。四个选项中只有（D）符合条件，故选（D）。
例2：Louis T. Wright, a surgeon, developed ingenious orthopedic braces 5, ___, and supervised the first use of Aureomycin on human patients. (A) treating skull 6 fractures that he pioneered in (B) pioneered in treating skull fractures (C) which pioneered in treating skull fractures (D) he was a pioneer in the treatment of skull fractures 分析：空格后面是and, 空格处缺少和developed、supervised平行的谓语动词，因此选择（B）。
