   Many ecologists now think that the relative long-term stability of climax 1 communities comes not from diversity but from the “patchiness” of the environment; an environment that varies from place to place supports more kinds of organisms than an environment that is uniform. (TPO 3 The Long-Term Stability of Ecosystems)


  托福阅读长难句句子分析:本句由分号连接了两个分句,分号前主句的谓语动词是think,而that则引导了宾语从句,表达了许多生态学家对此的看法。在这个宾语从句中,两个名词diversity和the patchiness由not from…but from...结构连接,是并列关系,此并列结构表示“不是来自于……,而是来自于……”,阅读重点应该是but from后面的内容。分号后主句的谓语动词是supports,还有两个that引导的定语从句,修饰各自前面的environment。
