But the Nobel Foundation’s limit of three recipients per prize, each of whom must still be living, has long been outgrown by the collaborative nature of modern research—as will be demonstrated by the inevitable row over who is ignored when it comes to acknowledging the discovery of the Higgs boson.
【例句解析】：本句主干为But the Nobel Foundation’s limit has long been outgrown by the collaborative nature of modern research，属被动语态。“of three recipients per prize, each of whom must still be living, ”属of短语作后置定语修饰limit，其中又包括whom引导的一个定语从句(each of whom must still be living)修饰recipients。破折号后部分是as引导的非限制性定语从句，修饰前面主句并对之进行举例解释;who is ignored when it comes to acknowledging the discovery of the Higgs boson属who引导的宾语从句，作介词over的宾语，其中又包括一个when引导的时间状语从句，根据就近原则，修饰前面的who is ignored。

【难点点拨】：recipient：接受者;outgrow：比……长得高或快;collaborative：协作的;row：争吵;the Higgs boson：希格斯波色子。
【例句释义】：但是诺贝尔基金会规定：每个奖项只能有三名接受者，且每个接受者都未离世。随着现代研究越来越具有协作性，此种规定早就已经不适用了。 ——例如，当提到希格斯波色子的发现时，人们往往会不可避免地争论谁被忽略了，这也就证明了诺贝尔基金会此种规定的不合理性。
