【语法真题100练】GMAT考生必看SC高分秘籍（二十六练）

GMAT语法题，又称句子改错题(sentence correction)，是整个GMAT考试中对考生英语语法能力考查要求最高的题型，也往往是中国学生最为头疼的一类题目。没有扎实的语法基础和一定的逻辑分析能力，想要做好语法题难度极高。怎样做好GMAT语法题?下面小编就通过一些经典真题的实例解析，为大家全面讲解GMAT语法题的解题思路和方法技巧。

实例题目：

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds;pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

(A) pollinating banana, breadfruit, and mango trees; and indirectly help produce

(B) pollinating banana, breadfruit, and mango trees; and indirectly helping to produce

(C) pollinating banana, breadfruit, and mango trees; and they indirectly help to produce

(D) they pollinate banana, breadfruit, and mango trees; and indirectly help producing

(E) they pollinate banana, breadfruit, and mango trees; indirectly helping the producing of

选项分析：

(A)pollinating banana, breadfruit, and mango trees; and indirectly help produce

【错误】 平行结构： 本题中“;”连接的是平行结构，“aiding……”“pollinating……”和“help”本应形成“A……;B……;and C……”的平行结构，但“help……”、“aiding……”和“pollinating……”三者语法功能不一致，无法平行。

(B)pollinating banana, breadfruit, and mango trees; and indirectly helping to produce

【正确】 分号连接的是平行结构(不仅仅用于连接两个主谓结构)，将“aiding in the dispersal of cashew, date, and fig seeds”、“pollinating banana, breadfruit, and mango trees”和“indirectly helping to produce”三个结构平行在一起形成了“A; B; and C”结构。

【大意】 热带蝙蝠在雨林生态系统中扮演重要角色，帮助散播海枣、腰果和无花果的种子;为香蕉、面包果、芒果的树授粉;并通过为龙舌兰授粉而帮助生产龙舌兰酒。

(C)pollinating banana, breadfruit, and mango trees; and they indirectly help to produce

【错误】 平行结构：类似地，见(A)。

(D)they pollinate banana, breadfruit, and mango trees; and indirectly help producing

【错误】 平行结构：类似地，见(A)。

(E)they pollinate banana, breadfruit, and mango trees; indirectly helping the producing of

【错误】 平行结构：类似地，见(A)。

解题思路：

(B)中出现了“aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly helping to produce”,合理正确的平行结构，其他选项各有各的不平行，因此选择(B)。
