First of all, sorry if this question is not exact place to ask.
Well, my question is if I write: "Will start working on the project, once I receive the payment or received the payment"? Which one is correct, is it receive or received???
I will start working on the project once I receive the payment.
I will start working on the project once payment is received.
I will start working on the project once I receive payment.
I will start working on the project once I receive a payment.
Also, I don't know to use to be
??This is a statement, not a question. Only use a question mark when asking a question. How to use "To be" - Kindly, give two - three examples with explanations, if possible. The answer requires more than a few examples. I suggest that you read more about "to be" and, if you have a teacher, ask about this. You can, of course, post a few samples here for comments.
I will never get to know how to use both tenses (both are more than one. In general, add an "s" to indicate a plural) in one sentence - Please, suggest some other resources to me. The sentence above is only one example.
Waiting for your prompt reply.
