they are usually visit their grandparents的拼写是否正确?

Answer 1

拼写正确，语法不对，多了个谓语动词。
they are usually visit their grandparents（are和visit都是动词，同一个句子中不能出现两个谓语动词）所以要去掉are，变为：
they usually visit their grandparents
他们经常探望祖父母。

Answer 2

如果单论拼写这些词到都是拼对了 但是语法有问题 visit在这里作动词 探望 拜访 be动词are后面不能直接跟visit原型 可以把are去掉

Answer 3

时态不对。usually用一般时，不用时行时。
They usually visit their grandparents.
这句去usually 更好些，
They are visiting their grandparents.他们正在......
