=There is fear growing among vice-chancellors that this revenue as well as the cultural, academic and economic benefit international students bring--is being put at risk.

解析：以上句子主干为“There is growing fear among vice-chancellor this revenue is being put at risk”

句子主语：fear

句子主语同位语：that this revenue--as well as the cultural, academic and economic benefit international students bring--is being put at risk.

句子主谓：is growing

句子状语：among vice-chancellors

同位语从句结构分析

同位语从句主语：this revenue as well as the cultural, academic and economic benefit international students bring

同位语从句谓语：is being put at risk

同位语从句主语结构分析：this revenue as well as the cultural, academic and economic benefit international students bring

并列主语(1):this revenue

连词：as well as（连词重点在前面，有前面名词确定谓语单复数）

并列主语(2):the cultural academic and economic benefit (关系代词that/which省略)international students bring

备注：并列主语(2)带有一个定语从句，international students bring修饰前面的名词benefit

根据连词as well as 特点，谓语单复数由并列主语1决定，所以后面谓语动词为单数is being put at risk
