Use #1. The second is not natural.

Thank you. Alphecca.

Can you explain further why it is un-natural? How is the 'the' working here to make it unnatural?

The + v-ing refers to a specific event or action:

We are planning to watch the running of the marathon.
We saw the unveiling of the new sculpture.
The breaking of bread and (the) drinking of wine is an important ritual in Christian churches.
We came into the room just as the judging of the quilts was about to begin.

Thank you.

Then, when you are cleaning a room, which one is correct to say, besides "I am cleaning"?
1. I am doning the cleaning.
2. I am doing cleaning.

1. I am doing the (weekly) cleaning -- the sweeping, the mopping, the dusting and the polishing.

Thank you again.

on another thread, I asked a similar question for watching a tv program, and no 'the' seemed to sound better was a kind conclusion. Can you tell me if it is so and why you (can't)don't find the term 'specific action' in this context?

1. I am watching (the) jelly-making.

And also is 'I am doing cleaning' completely wrong, or does this have a different m

Is "am doing cleaning" a catenative verb phrase? In other words, is "cleaning" a part of the catenative verb structure or is it an object of the verb "doing"?

onizo1. I am watching (the) jelly-making.

The definite article is not used with the gerund after certain catenative verbs, such as remember.
But, in certain (rare) cases, we do add the definite article.

I remember closing and locking the door, but I don't remember what happened later. (Common)
He remembers the closing and the lockin

Thank you Alphecca,

I haven't grasped your answer well.
To go simple, can I ask you the same question: so, you think 'the' is necessary in the sentence of 'I am watch the jelly-making'? Is it?
Then, can you also tell me the meaning of the same sentence without 'the', if anybody uses it? Or would simply consider it wrong?
