题干
The well-known "new great inventions" of modern China have made our daily lives more convenient.
High-speed trains
China created its first high-speed railway line in 2008.Since then，the number of passenger trips has grown by over 30 percent every year. By 2016，more than 5 billion trips had been taken on the trains. By 2020，one-fifth of the country's 150，000-km railway network will be used by the trains. This network will link more than 80 percent of major cities across China.
Mobile payment
Mobile payment is turning China into a “cashless society”. Instead of paying by cash（现金），customers now pay for their goods and some kinds of bills simply by typing a short password into the Alipay or WeChat Pay on their mobile phones.
Shared bikes
China has surprised the world with how quickly shared bikes are widely used. Nowadays，bike users can simply pick up or park the bike on the street through GPS and smart phone apps.
Online shopping
With around 751 million Internet users，China has been the world's largest and fastest-growing online shopping market. Because of lower costs and fewer licensing requirements（执照要求），it's easier for sellers to open an online shop in China. In 2016，more than 20 million jobs of rural areas were created，with over 8.1 million running their own online shops.
