今日长难句：

This classical model has traditionally produced prestigious universities, but it is now challenged by the digitalisation of society--which allows everybody who is connected to the internet to access learning--and by the need to acquire skills in step with a fast-changing world.

传统上，这种古典主义模式造就了享有盛誉的大学，但如今却面临挑战：社会的数字化让所有能连接互联网的人都有学习的机会，且人们需要获得新技能以跟上快速变化的世界。

分析：

第一步：简单划分句子成分，进行断句。

This classical model /has traditionally produced /prestigious universities, but /it is now challenged /by the digitalisation of society/--which allows everybody /who is connected to the internet /to access learning--/and by the need /to acquire skills /in step with /a fast-changing world.

第二步删繁就简，抓动词看主语。去掉较长的修饰和补充说明功能的成分（例如由长到短定语从句、介词短语、形容词、副词）从而先分析出句子的主干核心要义，看到简单的支撑句子的主框架。

第三步我们再来看从句和介词短语，把各种细节还原添加到我们已经得到的信息中来，就是句子清晰完整的全貌了。

This classical model /has traditionally produced/ prestigious universities, but/ it is now challenged /by the digitalization of society/--which allows everybody /who is connected to the internet/ to access learning--/and by the need /to acquire skills/ in step with/ a fast-changing world.

非限定性定语从句，修饰数字化digitalization, 作为“社会的数字化”的进一步解释说明，类似插入语，所以可以最后再来细看这一句。
