Question

The British constitution is to a large extent a product of the historical events described above.
这里 to a large extent是不是状语修饰is啊?

Answer 1

to a large extent 的确是状语,意思为“在很大程度上”,因为是状语,所以可以放在句中的任意位置,习惯上把它放到句首：To a large extent ,the British constitution is a product of the historical events described above.
也可以说是修饰is
