Hello everyone!
I've got two questions to ask:
1. Are "be going to" and the Present Continuous two completely interchangeable forms when we talk about expressing future plans? Is there any difference between "Henry
is having a birthday party on Saturday" and "Henry
is going to have a birthday party on Saturday"?
2. What is the question tag for the sentence "I am here..."? Is there a question tag for this one at all?
Thank you very much!
