长难句，顾名思义，既长又难，主要难在用词、结构等方面，其典型特征是从句套从句、大词小词轮番上阵。阅读理解得分低，往往是因为文章看不懂，文章中的句子之所以难以理解，有许多原因，其中一个主要原因是句子太长或者句子结构复杂。今天，文都跟大家来分析一下这几个长难句，希望能够帮助到大家。
【长难句1】
In Europe，where forestry is ecologically more advanced, the non-commercial tree species are recognized as members of native forest community, to be preserved as such, within reason.(2010年翻译)
在生态林业更为发达的欧洲，没有商业价值的树种被合理地视为当地森林群落的成员，同样地得到保护。
【解析】
该句的难点在于定语从句，即“where forestry is ecologically more advanced”，修饰Europe。其他考点结构：“of native forest community”作定语，修饰members;“within reason”介词短语作状语，修饰动词“are recognized as”。
