二、英语答题示范
题目：请根据以下情景，用英语写一篇短文。
情景：你是一名大学生，最近参加了一次志愿者活动，帮助贫困山区的孩子们改善生活条件。请描述你的所见所感。
答案：
Last weekend, I participated in a volunteer activity to help improve the living conditions of children in a poverty-stricken mountain area. It was an unforgettable experience that left a deep impression on me.
Upon arrival, I was amazed at the harsh living environment. Many children lived in small, dilapidated houses without electricity or running water. Despite the difficult conditions, they were full of hope and dreams.
During our stay, we distributed food, clothing, and school supplies to the children. We also organized educational activities to help them improve their language skills and knowledge. I was deeply moved by their enthusiasm and determination to change their lives.
The experience taught me the importance of empathy and compassion. It made me realize that we should never take our blessings for granted and always be willing to help those in need. I am grateful for this opportunity to make a difference in the lives of these children.
三、数学答题示范
题目：已知函数f(x) = x^3 - 3x^2 + 4x - 1，求f(x)的极值。
答案：
1. 求导数：f'(x) = 3x^2 - 6x + 4。
2. 令f'(x) = 0，解得x1 = 1，x2 = 2/3。
3. 求二阶导数：f''(x) = 6x - 6。
4. 当x = 1时，f''(1) = 0，为拐点；当x = 2/3时，f''(2/3) = 0，为拐点。
5. 求f(1) = 1，f(2/3) = 1/27。
综上所述，f(x)的极小值为1/27，极大值为1。
