尊敬的老师们，亲爱的同学们：

大家好！今天我站在这里，非常荣幸能够和大家分享我的想法。我想谈谈关于“梦想与坚持”的话题。

每个人心中都有一个梦想。梦想是我们的方向标，它指引我们前行。然而，通往梦想的道路并不是一帆风顺的。我们需要面对困难，需要克服挑战。在这个过程中，坚持显得尤为重要。

我记得小时候，我曾经梦想成为一名科学家。但是，在学习的过程中，我发现物理和数学对我来说并不容易。有时候，我会感到沮丧，甚至想要放弃。但我知道，如果我不坚持下去，我就永远无法实现我的梦想。所以我选择了坚持，我每天花更多的时间去学习，向老师请教，与同学讨论。最终，我的努力得到了回报，我在物理竞赛中获得了优异的成绩。

坚持不仅仅是面对困难时的一种态度，它更是一种习惯。当我们养成坚持的习惯时，我们会发现，无论遇到什么困难，我们都能迎刃而解。正如一句英文谚语所说：“Where there's a will, there's a way.”（有志者，事竟成）。

让我们一起努力，为了我们的梦想而坚持。不要害怕失败，因为每一次失败都是我们成长的机会。只要我们坚持不懈，就一定能够实现我们的梦想。

谢谢大家！

Dear teachers and dear classmates,

Good day! I am very honored to stand here today and share my thoughts with you. I would like to talk about the topic of "dreams and persistence."

Everyone has a dream in their heart. A dream is our compass, guiding us forward. However, the road to realizing our dreams is not always smooth. We need to face difficulties and overcome challenges. In this process, persistence is particularly important.

I remember when I was a child, I once dreamed of becoming a scientist. But during my studies, I found that physics and mathematics were not easy for me. Sometimes, I felt frustrated and even wanted to give up. But I knew that if I didn't persist, I would never be able to realize my dream. So I chose to persist, spending more time studying every day, seeking advice from teachers, and discussing with classmates. Eventually, my efforts paid off, and I achieved excellent results in the physics competition.

Persistence is not just an attitude in the face of difficulties; it is also a habit. When we develop the habit of persistence, we will find that no matter what difficulties we encounter, we can solve them. As an English proverb says: "Where there's a will, there's a way." (有志者，事竟成).

Let us work hard together and persist for our dreams. Don't be afraid of failure because every failure is an opportunity for our growth. As long as we persist, we will definitely achieve our dreams.

Thank you all!
