Are you interested in the popular shopping culture—Singles Day? I'd like to inform you    1     some information about it.

There are    2    (vary) theories about the origin of Singles Day in China. One of the popular theories is that Singles Day originated from campus culture. In 1993，four senior students at Nanjing University came up with the idea of organizing activities on Nov.11 as a day for single people. Gradually    3    (accept) by society, this festival attracts more and more people. With the spread of media and online culture, Singles Day is now hugely popular.

At present, Nov.11 is a shopping carnival.“Double 11” with the purpose of the online promotion    4    (hold) by Taobao (Tmall) on Nov.11，2009. With the    5    (tend) of shopping online, the turnover(营业额）of “ Double 11” Shopping Festival reached 213.5 billion in 2018, rising    6    (steady), which is a delight to sellers.

When shopping day meets Singles Day, what will people do? Perhaps, this special day makes    7     difference to those who are in their forties or older ages, but young people are loyal consumers who will take risks of    8    (run) out of their money    9    (purchase). It is the young consumers    10     have strong desire to buy that day. They like the discounts of the goods.

It is clear that April Fools' Day is one of the most widely recognized    1    (holiday) in the Western world. Children play tricks    2    parents and many people are fooled. But why? How did April Fools' Day begin, and how did it become an    3    (globe)phenomenon? Nobody    4    (real)knows. April Fools' Day is apparently an ancient enough tradition    5    the earliest recorded mentions.

One likely explanation is the Roman tradition of Hilaria, a spring festival    6    (hold) around March 25 in honor of the first day of the year    7    (long) than the night. It's hard    8    (say) whether this ancient revel's(狂欢)similarity to modern April Fools' Day are by accident or not, as the first recorded mentions of the holiday didn't appear until several hundred years later. The first mention of April Fools' Day in Britain    9    (come) in 1686, when John Aubrey described April first as a "Fools' holy day".

    10    is clear that the habit of sending springtime rubes(乡巴佬)on a "fool's day" was popular in Europe by the late 1600s. On April Fools' Day, 1698, so many people were tricked into coming to the Tower of London to watch the "washing of the lions" that a local newspaper had to explain it.

If you stop a random person on the street in China, there’s a pretty good chance their surname     1     (be) either Wang, Li, Zhang, Liu or Chen. That’s     2     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.     3     (put) that in perspective, the United States reported 6. 3 million surnames in its 2010 census.

There are a few reasons for this: China is less     4     (racial) diverse than countries such as the US, where a wealth of minority groups increase surname diversity. It also has to do     5     language; you can’t just add a random stroke to a Chinese character and create a new surname.

But there’s also another factor at play: technology. With China     6     (roar) 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     7     (code) into computer systems. That meant     8     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 predicament, according to Xinhua.

People with rare characters in their names,     9    aren’t compatible with existing computer systems, can get left behind — pushing many to change their names for the sake of     10    (convenient), even if it means abandoning centuries of heritage and language.

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.
