Describe a time when you worked in a group
You should say:
When it was
What you did
Who you worked with
And explain why you worked in the group

Last year, I attended the Mathematical Contest in Modeling （美国数学建模竞赛）where I worked with a group of close clas*ates. By the way MCM is a contest where teams of undergraduates use mathematical modeling to present their solutions to real-world problems.

To win this, we spent 6 months learning mathematical models in two ways, including reading books and using modeling software. Firstly; we read a series of books, such as ^z An Introduction to Mathematical Modeling ⁷ written by Edwards. Those books are very useful as they introduce various mathematical modeling methods and show examples of how they are applied in business, science, and engineering. Besides, we also used computer software such as Matlab to simulate some business problems with models. Firstly; we made assumptions, chose mathematical approaches, and assessed the usefulness and accuracy of modeling problems. Then we reworked and adjusted the model until it provided an accurate and predictive result of the situation.

I felt very excited and happy to work with them. Firstly we reaped a great return from our hard work, as we got a prize for ”Meritorious Winner” at the end. Besides, with this contest’s preparation, I had a deeper understanding of many mathematical concepts, such as statistics and equations. I was really proud of our achievement.

故事简介：去年，我曾和一群同学参加了美国数学建模竞赛。顺便说一下，MCM是一个竞赛，在这个竞赛中，本科生 团队使用数学建模来展示他们对现实世界问题的解决方案。

为了赢得这个奖项，我们花了6个月的时间，通过阅读 书籍和使用建模软件两种方式来学习数学模型。首先，我们读了一系列的书，比如爱德华兹写的《数学建模入门》。 这些书非常有用，因为它们介绍了各种数学建模方法，并展示了如何在商业、科学和工程中应用这些方法的例子。 此外，我们还使用Matlab等计算机软件，用模型模拟了一些商业问题。为了解决建模问题，我们做出假设，选择数 学方法，并评估解决方案的有效性和准确性。然后我们重新修改和调整模型，直到它提供了一个准确的预测结果的 情况。

和他们一起工作，我感到非常兴奋和高兴。首先，我们收获了巨大的回报从我们的努力工作，我们得到了一 个“有功赢家”在最后。此外，随着这次比赛的准备，我对很多数学概念有了更深的了解，比如统计和方程，我为 我们的成绩感到骄傲。
