UNIT 3 课时跟踪检测（三） 阅读写作融会练 Ⅰ.阅读理解 If you stop a random person on the street in China, there's a pretty good chance that their surname would be either Wang, Li, Zhang, Liu or Chen.That's because those are the five most common surnames in China — shared by 30% of the population. And the vast majority of the population share just 100 of those surnames. In comparison, the United States reported 6.3 million surnames in its 2010 census. There are a few reasons for this：China is less racially diverse than countries such as the US, where a wealth of minority groups increase surname diversity (多样性). It also has to do with language; you can't just add a random stroke (音节) to a Chinese character and create a new surname. But there's also another factor at play：technology. With China roaring into the digital age, nearly everything has moved online — from making appointments to buying train tickets. The main problem is that not all Chinese characters have been coded into computer systems. That meant a world of trouble if you happened to have a rare character in your name. As of 2017, up to 60 million Chinese citizens faced this problem, according to Xinhua. People with rare characters in their names, which aren't compatible(兼容的) with existing computer systems, can get left behind — pushing many to change their names for the sake of convenience, even if it means abandoning centuries of heritage and languages. To try to address this, experts have increased the database from 32,000 characters to 70,000 characters, according to the government. They're still working to expand it to include more than 90,000 characters, said Chen Jiawei, an associate professor at Beijing Normal University. 语篇解读：本文是一篇说明文。文章介绍了中国汉语言文化中的姓氏文化。 1．What can be learned from the comparison according to Paragraph 1?
