浙江省金华市婺城区2024-2025学年九年级上学期期末英语试题
You may feel that math is difficult and boring. Is it possible that you' ve been looking at math in the wrong way? Li Xing, a math professor at Ning Xia University, thinks math can be beautiful and fun. I complete agree with what he said.
Numbers are beautiful
There is math hidden in beautiful human bodies. Measure (测量) the length from your head to your belly button and from your belly button to your feet. The ratio (比例) of these two numbers is always around 0.618. This is the golden ratio, which can be seen everywhere, like in nature, music and paintings.
In Chinese poems, we can also see the beauty of numbers. As Li Bai wrote, "My skiff (小船) has left ten thousand mountains far away", "A thousand miles in one day",— all these numbers show how fast Li Bai traveled and how happy he felt.
Curves(曲线) are beautiful
"Sine curves" are beautiful. They go towards the two opposite directions on and on without ever ending. When you look at them, you may feel like standing by the sea and watching the waves slowly moving. "Tangent curve" is like a waterfall, just as Li Bai wrote, "dashing(猛冲) down three thousand feetfrom on high".
Formulas(公式) are beautiful
There are some amazing formulas. In a right-angled triangle (直角三角形), the square of the longest side is equal to the sum of the squares of the other two sides. How amazing! Just as Chinese-American mathematician Chern Shingshen said, "Math is fun!"
Here are four very great and famous people in China. They work very hard and have influenced(影响) our lives a lot.
