Of all the changes that have taken place in English-language newspapers during the past quarter-century, perhaps the most far-reaching has been the inexorable decline in the scope and seriousness of their arts coverage.
重点短语:take place(发生)
解析:
本句是一个主从复合句。句子主干为“the most far-reaching has been the inexorable decline”,“in the scope and seriousness of their arts coverage”是介词短语用于修饰“decline”,补充说明了在哪些方面是下降的。除此之外,句子前半部分开头是介词短语“Of all the changes”作状语,“that”是从属连词,引导定语从句,修饰“changes”。“during the past quarter-century”是时间状语。
翻译:
在过去的25年英文报纸所发生的变化中,影响最深远的可能就是它们对艺术方面的报道在范围和严肃程度上都无可改变地缩小和降低了。
