主谓宾和谓语结构分析

主谓宾和谓语结构分析New college students, even the brightest and most successful ones, are most at risk from these effects because the Internet is important for their studies and because they are just entering a world where their online habits are no longer monitored by concerned parents.

Answer 1

主句是New college students are most at risk from these effects，
其中这个主句的主语是New college students，
谓语系动词是are，
at risk from these effects是介宾短语做表语；
后面and连接两个由because引导的原因状语从句，
第一个是because the Internet is important for their studies，
第二个是because they are just entering a world
其中第二个原因状语从句有一个定语从句where their online habits are no longer monitored by concerned parents，
先行词是a world, 在从句中作地点状语
