Electric bicycles have become one of the most popular vehicles (交通工具) in people’s daily life, whether in the countryside or in cities. They run on battery-operated (用电池发动的) motors. Electric bicycles can run much faster than bikes and they are very easy to ride.
They were first made in the 1980s in China, but they were not popular at that time. Today, thanks to the improvement on the quality (质量) of the batteries, electric bicycles sell much better. There are over 100 electric bicycles makers in China. Now China is one of the largest makers of electric bicycles in the world, and many people ride them to work, to send children to schools, to go to the supermarkets and so on.
However, electric bicycles also have disadvantages. The most important one is that they are not safe enough for people who ride them. There are many accidents caused by electric bicycles because of their fast speed. People must be careful when riding electric bicycles. At the same time, people should wear helmets (头盔) when riding electric bicycles. Check the batteries as often as possible. Keeping safe is the most important thing.

Not long ago, a senior high school student caught much attention at the second World Laureates Forum (世界顶尖科学家论坛) in Shanghai. She is Tan Fanglin, a senior high school student from Shanghai.
The forum brought nearly 70 world’s top scientists together to discuss important issues (议题) about science. Besides the world’s top scientists, the forum also invited many young scientists. Tan Fanglin was among them, and as a 15-year-old girl, she was the youngest member in the meeting. Her research has improved people’s understanding of the connections between the Fibonacci sequence and Bezout numbers (斐波那契数列与贝祖数). The findings have won her many prizes in youth innovation (创新) competitions in Shanghai and elsewhere in China.
From a very young age, Tan has always been crazy about math. This is largely because of the influence of her father, who is a math teacher in East China Normal University. According to Tan’s head teacher, she never takes after-school classes or too many exercises. Her achievements come from her strong interest in math and the right study method.
Talking about her experience, Tan said, “Taking part in the WLA Forum and communicating with great scientists face to face have further encouraged me to do scientific research like math and I dream of achieving good research results like the top scientists. To make my dream come true, I’ll have to keep learning.”
