to varying degrees 是什么成分

The most important change, however, was the shift from diets based exclusively on food collection to those based to varying degrees on food production.

句中 to varying degrees 是什么成分,位置可以变动吗?

the shift from diets based exclusively on food collection to those based to varying degrees on food production

1. 蓝色的from...to...是介词词组,整个介词短语作the shift 的定语。

2. 紫色的to varying degrees 是固定短语,是to ...degree 结构,意为“在不同程度上”,插在based on food production 中间。可以将其放在句末,让其仍然修饰based。不过,放在based 之后最好,跟前面的exclusively 平行并列。

3. 句中有两个作定语的based on 词组:(1)based on food collection (2)based on food production

the shift from diets based exclusively on food collection to those based to varying degrees on food production.

those = those diets 后接过去分词短语作限制性定语。based on...基于...的饮食。

to varing degrees 为程度状语,修饰based.  该程度状语本可以移至on 介词短语之后:

the shift from diets based exclusively on food collection to those based on food production to varying degrees.

但这样安排结构,可能导致读者误以为to varying degrees是修饰the shift的。因此,这个程度状语还是放在based 和 on之间为宜,以避免误读。
