令很多同学感到苦恼的是他们通过训练已经能够迅速找到雅思阅读答案关键信息的所在位置，但是就是读不懂句子。论及原因，不认识单词为首要因素，但是就算认识单词，很多同学也不能完全掌握该句的意思。今天苏州新航道雅思培训班小编给大家带来一道经典长难句解析。

1. Archaeologists in recent decades have developed ‘ethnoarchaeology', where, like ethnographers, they live among contemporary communities, but with the specific purpose of learning how such societies use material culture—how they make their tools and weapons, why they build their settlements where they do, and so on. (剑4, test4 passage 2)

分析：本句主句为“Archaeologists in recent decades have developed ‘ethnoarchaeology'”;“where, like ethnographers, they live among contemporary communities, but with the specific purpose of learning how such societies use material culture”为定语从句，做‘ethnoarchaeology'的定语，关系词为where;“how such societies use material culture”为how引导的宾语从句，做learn的宾语;“how they make their tools and weapons, why they build their settlements where they do”位于破折号后面，解释前文中的“how such societies use material culture”, 也是how和why引导的宾语从句;“where they do”为where引导的地点状语从句。
