Good afternoon, everyone!
The topic of my speech today is "Cooperate with others".
In our daily life and study, if we want to accomplish our work efficiently, we must all learn to cooperate
with others. Cooperation can save us a lot of time and energy. Additionally, we can learn much from our
partners by cooperating with them.
When we cooperate with someone we like, we will feel very happy. We can share our pleasure(joys)and
sadness(sorrows)with him. But it challenges us to get along with others to cooperate with someone we dislike
(hate). Besides/Moreover/What's more, we should focus on our work, instead of(rather than)our partners.
Perhaps in working together with him for a long time, we'll learn(find out)that he is a man to get along well
with.
How can we become a good partner? In my opinion, we should try to listen to others. If they make
mistakes, we also try to point them out. Thirdly, we mustn't embarrass others to make them in unfavorable
position.
Thank you for your listening!
