首先每个句子都必须有一个主谓结构，其次主语和谓语要在单复数形式和逻辑意义上达到一致，在GMAT语法考试中，主谓一致基本在每个试题中都会出现，判断主谓一致还能为分析好句子结构有帮助。今天我们就来讲解几道prep-07-1部分的GMAT语法主谓一致练习题(一)。
例：
The list of animals that exhibits a preference of either using the right or the left hand (i.e., claw,paw, or foot) has been expanded to include the lower vertebrates.
(A) exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
(B) exhibits the preference to use either the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes
(C) exhibit a preference in either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
(D) exhibit a preference for using either the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
(E) exhibit the preference as to either using the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes
答案解析：
(A) that指代animals,因此that从句的谓语应该用复数; either…or…结构中using the right和left hand不平行
(B) exhibits使用错误导致主谓不一致; and includes和has been平行,共同作为The list的谓语.则该句子可化为The list… has been expanded the lower vertebrates和The list… includes the lower vertebrates两个句子,前者明显不通.
(C) either using the right or the left hand结构不平行
(D) 正确, 注意到了两个地方的主谓一致;the right和the left平行且使用to include避免了B选项的错误
(E) as表示作为…的意思,后面应该接简单名词; either…or结构不平行; has been expanded and includes改变了原句的意思
