托福阅读长难句解析　Cleisthenes’ principal contribution to the creation of democracy at Athens was to complete the long process of weakening family and clan structures, especially among the aristocrats, and to set in their place locality-based corporations called demes, which became the point of entry for all civic and most religious life in Athens.

　　难句类型：

　　插入+并列+从句

　　解释：

　　1 主语修饰部分极多，容易疏忽核心词为contribution.

　　2 表语从句后 to complete…容易读丢。The process of.. 中weakening的宾语包括family和clan structures.

　　3 插入句“especially among the aristocrats”修饰“family and clan structures”

　　4 第二个and并列关系，是to complete… and to set…

　　5 后置定语 called domes 修饰 corporations.

　　6 which..从句修饰domes.

　　意群练习：
