题目内容：

Tom with his friends often____to see Beijing opera ____weekends.
weekend 前面用at?应该用on吧？1.goes,on 2.go ,at 3.goes,for 4.like,on

优质解答

1.goes;on Tom with his friends 其实主语是Tom,所以应该用单数原句可以改为Tom often goes to see Beijing opera with his friends on weekends.至于是否用at 或 on 我觉得是on weekends吧（我们书上是这么写的） ...
