你好!
I'm going to visit my grandparents this weekend.改为一般疑问句Are you going to visit your grandparents this weekend?或者Will you visit your grandparents this weekend?
What are you going to do this weekend?或者What will you do this weekend?是特殊疑问句。
如果有什么有关英语不懂的,您仍然可以问我,我会尽量最快的给您答复。谢谢!
Are you going to visit your grandparents this weekend?
楼下错误。
What are you going to do this weekend?
Are you going to visit your grandparents this weekend
