昨天我特别喜欢的政客进行了辩论。 他们集中讨论了现代社会中最紧迫的问题，每个人都在合理和逻辑上证实了他的观点。讨论很热烈；它持续了两个小时，所以我一直看着它结束了。有些结论我赞成，有些我不同意。 It's your original text， Here is my revision of your original text：昨天我特别喜欢的政客进行了辩论。Change to：昨天我和我特别喜欢的政客进行了辩论。 I think what you mean by this sentence is that yesterday I had a debate with my favorite politician。 The second sentence，他们Change to：我们。Because it's not that they have a discussion, it's you who have a discussion，So the first person is us，that is“我们” 它持续了两个小时，所以我一直看着它结束了Change to：我们讨论了两个小时之后结束了。What do you mean：It lasted two hours, so I kept watching him finish.（This expression is wrong.）And the revised meaning is：We talked about it for two hours and then it came to an end.（The expression in China is correct.） The rest of the sentences are correct！！It's great！excellent.I hope my answer will help you，thank you.
