|==??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)

a: 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memb

ers;“within reason”介词短语作状语，修饰动词“are recognized as”。

b: 该句译文是：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。?????
