题目：A Day I Will Never Forget
Last summer, I had an unforgettable experience that changed my life. It was the day I visited the Great Wall of China with my family.
We arrived at the foot of the Great Wall early in the morning. The sun was just rising, casting a golden glow over the ancient structure. As we began to climb, I could feel the weight of history pressing down on me. Each stone seemed to whisper stories of the past.
The climb was challenging, but the view from the top was worth every step. Looking out over the vast expanse of the Great Wall stretching into the distance, I felt a sense of pride and awe. This was not just a wall; it was a symbol of strength and perseverance.
That day on the Great Wall is one I will never forget. It taught me about history, culture, and the importance of determination. It was truly an experience that changed my perspective and made me appreciate the rich heritage of my country.

题目：The Importance of Environmental Protection
Environmental protection has become a hot topic in recent years as people are starting to realize the impact of human activities on our planet. In this essay, I will discuss the importance of environmental protection and what we can do to contribute to it.
Firstly, environmental protection is crucial for the well-being of all living creatures. Pollution, deforestation, and climate change are causing serious damage to ecosystems worldwide. If we do not take action now, future generations will suffer the consequences. Therefore, it is our responsibility to protect the environment for the sake of our planet and those who come after us.
Secondly, protecting the environment has economic benefits. Sustainable practices can lead to long-term economic growth by conserving resources and promoting green technologies. For example, investing in renewable energy sources like solar and wind power can create jobs and reduce reliance on fossil fuels. Moreover, eco-friendly products often appeal to consumers more than traditional ones, which can drive business success.
In conclusion, environmental protection is essential for both ecological and economic reasons. We must act now to preserve our planet for future generations. By adopting sustainable practices and raising awareness, we can make a significant difference in protecting the environment.
三、说明文
说明文是一种解释事物原理、功能或特征的文体。在高中英语写作中，说明文通常要求学生解释某项技术、过程或现象。

题目：How Does Photosynthesis Work?
Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy stored in glucose. This process is essential for life on Earth because it provides the foundation for almost all food chains. But how exactly does photosynthesis work? Let’s break it down into three main stages: light reactions, Calvin cycle, and respiration.
Light Reactions: These occur in the thylakoids of chloroplasts when sunlight hits chlorophyll molecules. The absorbed energy splits water molecules (H2O) into oxygen (O2), electrons, protons, and NADP+. Oxygen is released into the atmosphere, while electrons travel through the electron transport chain, creating a proton gradient across the thylakoid membrane. This gradient drives ATP synthesis from ADP and P_i.
Calvin Cycle: Also known as the “light-independent reactions” or “dark reactions,” this stage takes place in the stroma of chloroplasts where NADPH and ATP produced in the light reactions are used to fix carbon dioxide (CO2) into organic molecules. Through a series of enzyme-catalyzed steps, CO2 is converted into glucose (C6H12O6).
Respiration: Although not directly part of photosynthesis, cellular respiration works hand-in-hand with it. Glucose produced during photosynthesis is broken down in mitochondria to produce ATP, which powers cellular processes. Oxygen consumed during respiration comes back into play during photosynthesis, creating a continuous cycle.
By understanding these stages, we gain insight into why plants are vital for sustaining life on Earth. Photosynthesis not only produces food but also generates oxygen and absorbs carbon dioxide, helping to regulate atmospheric composition and combat global warming. It’s a marvelous natural process that underscores the interconnectedness of ecosystems.
