a person who has very good grade and he is a top students in university

整个句子?
a top students?
没这种说法.嗯嗯，整个句子，不知道对不对，没有who是不是也对啊？这块不太会。He is a top student in university who has a very good grade.这句把who 去掉行不行啊 he is a top student in vniversity has a very good grade.he is a top student in vniversity andhas a very good grade.加and为什么要加and啊？不加为什么不行啊？我不太懂，麻烦了。必须加and 。一个句子不能有两个谓语。is 是谓语。。你后面要再加一个谓语 has 中间必须加 and。你要表达的是下面的意思。He is a top student.He has a very good grade.如果两个句子要连接起来，中间就必须加and。不懂，就要大胆问。没人笑话你。加群号。259358932.纯粹英语学习交流。大伙一起交流。验证说明：English。 否则不让进。刚刚建立。
