There are many students go to study abroad.错在哪里

问题描述：

There are many students go to study abroad.错在哪里
这个句子哪里错了.
首先,go的词性是什么?是否是系动词.正确的改法There are many students go abroad to study.或者there are many students study abroad.那么正确句子中abroad是不是做表语?错误句子中go是什么动词?错误句中to study做什么成分,abroad作为地点副词在句子中应该在什么位置?用be going to改变study充当的成分,相当于study abroad.不是要句子改错,是要知道原句为什么是错的.
