"They haven't bought UFC for those bums. They have bought it for Platinum. Who will turn them into a Fortune 500 corporation."
My dear, I'm not into tutoring for free...usually. I'll do you this favor: reconstruct your jumbled mass of incomplete thoughts and awkward tense into a coherent thought in English.
"They did not buy the UFC for those bums; they bought it for the other bum Perry, who will lead them into bankruptcy if he becomes the face of the company."
You are quite welcome, my darling. No charge this time.
If I were you I wouldn't be expecting anything with that kind of half botched effort & you shouldn't be either. If you are going to correct someone then be ready to dive into the deep; don't leave it only after scratching the surface.
Let me get you through.
1. Is it "They did not buy the UFC for those bums" or is it "They haven't bought UFC for those bums"?
The event we are talking about took place about a year ago, which is a quite recent event in terms of sporting landscape. So it was a proper use of present perfect tense. We are not talking about our daily life where a difference in year will make it a distant past. So having the sentence in present perfect tense wasn't wrong. It's just a matter of interpretation.
2. "They haven't bought UFC for those bums", This is a perfect sentence which clearly maintains the SVO form of English. It is a meaningful sentence with a complete thought. Anyone reading that sentence will get a complete idea of that sentence. There is nothing incomplete about it.
3. "They did not buy
the UFC for those bums". Generally definite article is not used with
acronyms (initials that can be pronounced as a word), whereas it is with
initialisms (initials where the letters themselves are pronounced). However, with UFC it is different. Both Dana & CO & fans use the acronym UFC as a name or proper noun. Depending on their use case the definite article " The " is not required in front of UFC because of its usage as a proper noun.
4. "They did not buy the UFC for those bums;
they bought it for the other bum Perry. The highlighted part is an independent clause which can exist as a separate sentence. Joining them with a semicolon wasn't an absolute necessity & makes no drastic change.
5. The only crucial mistake you can single out from my original comment was the use of period after the sentence "
They have bought it for Platinum. Who will turn them into a Fortune 500 corporation." The second part was clearly a continuation of the first part and can't exist as a single entity. It clearly required a comma or a semicolon.
Now here comes the part where I will give you a suggestion. Refrain yourself from acting in such a condescending manner unless you are trying to appear as a snob. That will make our future conversations more delightful. Thank you.
