升旗仪式是学校教育的重要组成部分，我校升旗仪式采取学生组织参与的形式，旨在激发全体师生爱国爱党，提高全体学生规范意识，促进学生实现自我教育，营造振奋向上、锐意进取的积极氛围。<br> 本次升旗仪式的主持人是徐同学和许同学同学，演讲人是来自七年级一班的赵同学和霍同学。本周，七年级一班的同学为我们带来的演讲主题为：保护环境，保护生物多样性。 21世纪时挑战与机遇同在，希望与困难共存，它在为我们创造辉煌业绩的同时，也给我们带来了许多难题，其中首要的就是保护生态环境，保护生物多样性。<br><br>5月22日是国际生物多样性日，环境与我们的生存息息相关，文学家雨果曾经说过：“大自然既是善良的慈母，同时也是冷酷的屠夫”。人为的破坏环境，无异于自掘坟墓，不仅影响着经济的发展和社会的进步，甚至还威胁着人类的生存。生物多样性更是地球生命的基础，和每一个人也是密不可分的，它是人类重要的物质基础，维系着人类生存和发展。<br><br>同学们，我们是未来的主人，环保意识是现代人的重要标志，保护环境是我们大家义不容辞的责任，我们应该心系世界，着眼身边，立足校园，多弯腰捡拾垃果皮纸屑，不要随地乱扔垃圾。多走几步，不要穿越绿化带毁坏植被，保护动物植物。“勿以善小而不为，勿以恶小而为之”。让我们一起来保护地球母亲，净化绿色校园，让我们的校园更加美丽，让祖国的天更蓝，地更绿，水更清！ <br> In the 21st century, challenges and opportunities coexist, and hope and difficulties coexist. While it has created brilliant achievements for us, it has also brought us many problems, the most important is to protect the ecological environment and biodiversity.<div><br>The environment is closely related to our survival. The writer Hugo once said: "nature is not only a kind mother, but also a cold butcher". The destruction of environment not only affects economic development and social progress, but also threatens human survival. Biodiversity is the basis of life on earth and maintains human survival and development.</div><div><br>Students, we are the masters of the future. We should care about the world, focus on our side, base ourselves on the campus, bend down and pick up litter, and don't litter everywhere. Take more steps, don't cross the green belt, destroy vegetation, and protect animals and plants. “Don't do it with its little good and don’t do it with the small evil.” Let's protect mother earth, purify the green campus, make our campus more beautiful, and make the sky bluer, the ground greener and the water clearer in our motherland!</div>
