Of all the changes that have taken place in English-language newpapers during in the past quarter-century,....
为何开头的介词短语用of？有哪些实质意义吗？其他介词可以吗？
我查了以下原文：
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.
作者为了强调，把 Of all … century，放在了句首，假如改一下语序，就能比较容易理解了，如下：
Perhaps the most far-reaching of all the changes has been...
that have taken place in English-language newspapers during the past quarter-century 是个定语从句，修饰前面的 the changes.
简单例子如下：
Of all the students, Xiao Wang is the best.
=
Xiao Wang is the best of all the students.
期望上面的讲解，对你有所帮助。
