Describe a thing that you bought and felt pleased about
You should say:
What you bought
Where you bought it
What it is for
And explain why you felt pleased about it

A few weeks ago, I bought a book, which is called An Introduction to Mathematical Modeling from the Taobao platform. My professor David recommended this book, and it introduces various mathematical modeling methods and shows examples of how those methods are applied in business, science, and engineering.

I am pleased that I bought it because the book is instrumental for me, and it gives me various insights about mathematical modeling. For example, it shows that mathematics models have incredible power and beauty, and it is the key to innovations in most science, technology; engineering, and mathematics-related fields. Secondly; it helps us to manipulate the world around us. To solve modeling problems, we can make assumptions, choose mathematical approaches, and assess the solution for usefulness and accuracy. Then we can rework and adjust the model until it provides an accurate and predictive result of the situation. That’s fantastic.

Besides, it deepens my understanding of many mathematical concepts, such as statistics and equations, as I studied mathematics without understanding how to apply it in real life. Although I found it isn’t easy initially as I had to understand the complex mathematical concepts and methods, I learn modeling quite well after reading it repeatedly and doing some research.

故事简介:几周前,我在淘宝上买了一本书,名叫《数学建模概论》。我的教授大卫推荐这本书,它介绍了各种数学 建模的方法,并展示了如何应用这些方法在商业,科学和工程。

我很高兴我买了它,因为这本书对我来说很有用, 它给了我各种关于数学建模的见解。例如,它表明数学模型具有不可思议的力量和美丽,它是大多数科学、技术、 工程和数学相关领域创新的关键。其次,它帮助我们操纵我们周围的世界。为了解决建模问题,我们可以做出假设, 选择数学方法,并评估解决方案的实用性和准确性。然后我们可以重新工作和调整模型,直到它提供了一个准确的 和可预测的结果的情况。这太棒了。

此外,这也加深了我对许多数学概念的理解,如统计和方程式,因为我学习数 学却不知道如何将它应用到实际生活中。虽然一开始我发现建模并不容易,需要理解复杂的数学概念和方法,但是 经过反复阅读和研究,我学习的很好。
