I don't understand the difference between the participle and the gerund.
Are the following sentences correct? What's the difference in meaning?

#1. Mrs. Smith was the first to receive the prize.
#2. Mrs. Smith was the first receiving the prize.
#3. Mrs. Smith will be the first to receive the prize.
#4. Mrs. Smith will be the first receiving the prize.

I think all are correct but don't understand the difference between #1 and #2, and #3 and #4.

Here it the sentence in a correct form with the present participle. The meaning is different than with the infinitive.
She is the first one in line, wearing the blue dress, receiving the prize.
The extra phrases make the situation clear, that she is a particular person who is (at this time) receiving a prize.
Swiming strongly, she rescued the drowning boy. (2 participles, describing the state of the people)

Receiving the prize, Mrs Smith waved to the audience.

She is the first one in line, wearing the blue dress, receiving the prize.

I understand all of these sentences.
I can't understand only why #2 and #4 are incorrect.

#2. Mrs. Smith was the first receiving the prize.
#4. Mrs. Smith will be the first receiving the prize.

That may because I always try to understand the meaning of a sentence through my mother tongue, Japanese. I think that casyses everything.

Anyway, I'll remember clearly that all the teachers said #2 and #4 are incorrect. I wish I'll be able to solve this problem myself some day.

Thanks!

It is difficult to explain, but I try my best.

Think of "receiving"as a relative present time reference, and "to receive" being a relative future time reference. (Think of "I am receiving a prize", versus "I am going to receive a prize".

Mrs. Smith was the first to receive the prize - the time reference of "to receive" is future relative to the verb "was". This is the natural sense of "first" as a time reference.The action of receiving comes after that time in the past that relates to "was". (Mrs Smith was going to be the first person who will win the prize)
Mrs. Smith was the first receiving the prize. - "receiving would be the present time, relative to "was". It is only logical if "first" refers to a location, not time. Note that the verb is NOT "was receiving". The verb is "was". (a linking verb).

So we have to put some more context (location) in to make the "receiving" at the same relative present time as "was".
Mrs Smith was the first one in line, receiving the prize. (In this sentence, you can see at a time in the past, Mrs Smith was first in a line, and at that same time, she was receiving a prize)
I hope that makes it a bit clearer.
Wooow!!
How nice!!
A miracle!!

Welcome! This stuff comes so natural to me as a native speaker that I have to really think to analyze what's going on with the grammar...
