he is a student that .和he that .is a student有什么差别?

有一点区别,因为被定语从句修饰的成分不同,在表达意思时强调的部分就不一样.如：
He is a student that won the first prize. 他就是那个（得了一等奖的）学生.
He that won the first prize is a student. （得一等奖的那个人）是个学生.
问题补充：
这两句应该都没有语法错误吧还是什么—— 以我来看,第二句有点问题.英语中的要来给一个人“he“来加一个定语从句的话,一般不用限制性定语从句,而用非限制性定语从句.改成,he, who won the first prize, is a student. "who"领导的非限制性定语从句,用来对"he"是一个怎么样的人,加了一个修饰.
一般都用哪句的啊——He is a student that won the first prize. 和 He, who won the first prize, is a student. 用哪句,取决于在语境中,你的表达需要.
