The affirmative side could debate around the following points: Contribution and return are closely related: there is a close relationship between contribution and return. Only by giving first can you expect to get a return. Whether it was in work, study, or personal life, we all need to put in effort and sweat before we can reap results and rewards. Therefore, in the debate, it can be emphasized that effort and reward are related. Only by putting in enough effort can you get the corresponding reward. The returns are usually visible: the returns between effort and return are usually visible. When we put in effort, we usually see the corresponding results and gains. For example, when we put in enough effort in work or study, we usually get rewards such as improvement and harvest. Therefore, it can be emphasized in the debate that the reward is usually visible, and only by putting in enough effort can you see the corresponding reward. 3. Contribution and return are proportional: Contribution and return are proportional. Our efforts and returns are usually proportional. Only by putting in enough effort can we get the corresponding returns. For example, when we put in enough effort at work, we usually get a higher position, better salary, and other rewards. Therefore, in the debate, it can be emphasized that effort and return are proportional. Only by putting in enough effort can you get the corresponding return. Success requires constant effort: the relationship between effort and return is constantly accumulating and sublimating. Only by constantly putting in effort could one continuously reap rewards. Success is not something that can be achieved overnight. It requires constant perseverance and hard work. Therefore, it can be emphasized in the debate that success requires constant effort. Only by putting in enough effort can you achieve continuous success. The above are some points that the positive side can revolve around. They can be freely developed and supplemented according to the specific situation and topic of the debate.
