或：Even though the universities that accept students who have special athletic talents are often criticised, the advantages of doing this outweigh disadvantages.
误：Students who have special athletic talents should not become the scapegoat for lowering the university’s academic standards, they should be entitled to choose the appropriate university they like.
前后两句话之间不能用逗号，或用句号，或用分号。 be entitled to 后应跟名词，如：
Everyone is entitled to education. 人人都有受教育的权利。
I am entitled to an annual vacation of 15 days. 我每年有15天的休假。
前句的思想及表达都很好，特别是 scapegoat 一词的使用。
