Many Hands Make Light Work
Good morning, everyone! Have you heard of the saying "Many hands make light work." I think it means that when we meet difficulties, we can overcome them successfully by pulling together.
Last term, our school held a tug of war. It was difficult for our class, because the students in our class weren't strong enough to win the game. Before the game, the teacher and the students sat together and discussed how to win the game. Later, a student came up with a good idea. He
called on each of us to try our best in the game. He said, "If everyone spares no effort to do well intheir part, we can make contributions to our team." In the end, we won the game.
Everyone plays an important part in a team. And teamwork is the key to success.
That's all. Thanks for your listening.
Thanks!
