英语句子成分分析的问题

For example, a much higher proportion of girls study science when they attend girls' schools than girls in mixed schools.请问这句话成分有残缺吗？没有的话请问哪个是主语哪个是谓语呢？有的话又应该补什么呢？

Answer 1

原句：
For example, 【a much higher proportion of
girls主】 【study谓】【 science宾】【 to a high level 状】【when they attend girls’ schools时间状语从句】【 than their
counterparts主 in mixed schools定 do.比较状语从句】
你改的句：
For example, a much higher proportion of girls study science when they attend girls' schools than 【the】girls in mixed schools 【do】.这个do是不能省略的。

追问

为什么主语不是 a much higher proprotion的 proportion做主语呢，如果它不是主语，有这样作定语的吗？

追答

a much higher proportion of girls
这个主语是一个整体的。a much higher proportion of 是修饰girls的。
类似于a lot of这类的也是如此

Answer 2

没有
主语：girls
谓语：study
例如：上女子学校的女生比上混合学校的女生学习理科的比例高。
