实例题目：
Authoritative parents are more likely than permissive parents to have children who as adolescents are self-confident, high in self-esteem, and responsibly independent.
(A) Authoritative parents are more likely than permissive parents to have children who as adolescents are self-confident, high in self-esteem, and responsibly independent.
(B) Authoritative parents who are more likely than permissive parents to have adolescent children that are self-confident, high in self-esteem, and responsibly independent.
(C) Children of authoritative parents, rather than permissive parents, are the more likely to be self-confident, have a high self-esteem, and to be responsibly independent as adolescents.
(D) Children whose parents are authoritative rather than being permissive, are more likely to have self-confidence, a high self-esteem, and be responsibly independent when they are an adolescent.
(E) Rather than permissive parents, the children of authoritative parents are the more likely to have self-confidence, a high self-esteem, and to be responsibly independent as an adolescent.
选项分析：
(A)Authoritative parents are more likely than permissive parents to have children who as adolescents are self-confident, high in self-esteem, and responsibly independent.
【正确】 本选项正确使用了“more……than……”的比较句式，“authoritative parents”和“permissive parents”是比较结构中平行的两部分。补全省略的内容，本题的比较结构为“authoritative parents are more likely(to have children who……)than permissive parents (are likely) to have children who……”。“self-confident”、“high in self-esteem”、“responsibly independent”三者用“and”平行在一起，正确地构建了“A，B，and C”的平行结构。
【大意】 权威的父母比百依百顺的父母更有可能拥有在青春期自信、自尊、自立的孩子。
(B)Authoritative parents who are more likely than permissive parents to have adolescent children that are self-confident, high in self-esteem, and responsibly independent.
【错误】 句子结构：“are more likely……”成为了“who”引导的定语从句中的谓语，则主句失去谓语，主谓结构不完整。
(C)Children of authoritative parents, rather than permissive parents, are the more likely to be self-confident, have a high self-esteem, and to be responsibly independent as adolescents.
【错误】 平行结构：“to be self-confident(不定式), have a high self-esteem(动宾结构), and to be responsibly(不定式)”中三个平行对象语法功能不一致，无法用“and”平行在一起。
(D)Children whose parents are authoritative rather than being permissive, are more likely to have self-confidence, a high self-esteem, and be responsibly independent when they are an adolescent.
【错误1】 平行结构：“rather than”是平行结构标志词之一，应连接平行的对象(语法功能一致，逻辑含义对等)，而“being permissive”与“Children”两者语法功能不一致，无法用“rather than”平行。
【错误2】 平行结构：“to have self-confidence, a high self-esteem, and be responsibly independent”中三个平行对象语法功能不一致，无法平行。
(E)Rather than permissive parents, the children of authoritative parents are the more likely to have self-confidence, a high self-esteem, and to be responsibly independent as an adolescent.
【错误】 平行结构：“Rather than”连接的平行对象为“permissive parents”和“the children of authoritative parents”，两者虽然语法功能一致(都是名词性结构)，但在本句中逻辑含义不对等(父母和子女)，因此无法平行。
解题思路：
(B)的句子结构有问题，立即排除。
(C)、(D)、(E)没有正确使用平行结构，立即排除。
因此选择(A)。
