第一部分：数学
一、选择题
题目：若函数\(f(x) = ax^2 + bx + c\)的图像开口向上，且顶点坐标为\((1, -2)\)，则下列哪个选项正确？ 解析：由于开口向上，\(a > 0\)。顶点坐标为\((1, -2)\)，代入函数得\(f(1) = a + b + c = -2\)。根据顶点公式，\(b = -2a\)。因此，正确答案是A。
题目：已知等差数列\(\{a_n\}\)的前\(n\)项和为\(S_n\)，若\(S_3 = 9\)，\(S_5 = 25\)，则公差\(d\)为多少？ 解析：根据等差数列前\(n\)项和公式\(S_n = \frac{n}{2}(2a_1 + (n - 1)d)\)，代入\(S_3 = 9\)和\(S_5 = 25\)，解得\(d = 2\)。
二、填空题
- 题目：若函数\(f(x) = \frac{x^2 - 3x + 2}{x - 1}\)的图像的对称轴为\(x = 2\)，则\(a\)的值为多少？ 解析：由于对称轴为\(x = 2\)，代入函数得\(f(2) = 0\)，解得\(a = 0\)。
三、解答题
- 题目：已知函数\(f(x) = x^3 - 3x^2 + 4x + 1\)，求\(f'(x)\)。 解析：使用求导法则，得\(f'(x) = 3x^2 - 6x + 4\)。
第二部分：语文

In the past, people used to think that only humans could think and make decisions. However, with the development of artificial intelligence, this idea has changed. Now, machines can also think and make decisions.
问题：根据文章内容，下列哪个选项正确？
A. People used to think that only machines could think and make decisions. B. Machines can think and make decisions as well as humans. C. Machines can only make decisions based on pre-programmed instructions. D. Artificial intelligence has not changed people’s ideas about thinking and decision-making.
解析：正确答案是C。文章中提到，机器只能根据预编程的指令做出决策。
三、阅读理解
- 题目：阅读下面的文章，回答问题。
The Internet has become an indispensable part of our lives. It allows us to communicate with people all over the world, access information quickly, and even do business online. However, the Internet also has its drawbacks. For example, it can be a source of misinformation and cyberbullying.
