Ⅱ. 阅读理解[跨学科]
Still worried about your maths? You may feel it is difficult and boring. Is it because the way you think about maths is not right? Teens talked with Li Xing, a maths teacher at Ningxia University. We interviewed him if maths can be beautiful and fun. Here's what Li said.
Numbers are beautiful
Many people today want to have beautiful looks. But there is maths in beautiful human bodies. Measure(测量) the length(长度) from your head to your belly button(肚脐眼) and from your belly button to your feet. The ratio(比率) of these two numbers is always around 0.618. This is the golden ratio, and we can see it everywhere, like in nature, music, and drawings.
In Chinese poems, we can also see the beauty of numbers, which reminds us of a line, “ ▲ ”—the numbers show how fast Li Bai travelled and how happy he felt.
Curves are beautiful
Sine curves(正弦曲线) are beautiful too. They go towards the two opposite directions without end. When you look at them, you may feel like standing by the sea and watching the water waving slowly. The tangent curve(正切曲线) is like a waterfall. That's really “going down three thousand feet from on high”. If you do a maths problem and get that curve, you'll feel excited and fun.
So, where can you find the beautiful maths?
