Each year, the women of Olney, England, and Liberal, Kansas, compete in     1     unusual footrace. Dressed in     2     (apron) and headscarves, they wait at both towns’ starting lines. Each woman holds a frying pan     3     one pancake inside. At the signal, the women flip their pancakes and they are off.

This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney,     4     is the day before the Christian season of Lent(大斋期) begins. During Lent, many people decide to give up sugary or fatty foods.

Legend says that in 1445, an Olney woman     5     (make) pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and     6     (sudden) heard the church bells ring, signaling the     7     (begin) of the Shrove Tuesday service.     8     (realize) that she was going to be late for church, she     9     (race) out, still wearing her apron and headscarf and holding her frying pan with a pancake in it.

In the following years, the woman’s neighbors imitated her dash to church,     10     pancake racing was born. Olney women continue this Shrove Tuesday tradition more than five hundred years later.

Double 11, originating from some universities in Nanjing in     1     1990s, is called Singles Day in China because it falls     2    . Nov.11 by coincidence（巧合）when many young people will hold many parties to look for the one they love.

But in 2009 the online retail firm（零售公司）Alibaba adopted the day to promote a massive online shopping sale. It is said that the date was easy     3    (remember), and conveniently placed in a consumer spending lull（淡季）between National Day     4    Chinese New Year holiday.

Since 2011，Double 11     5    (become) the symbol of E-commerce, when people can buy lots of things they like at a low price. However, there are also some     6    (disadvantage). For example, people might buy some products they don't need at all or buy something with a high price but in low quality. What's     7    (bad), there are always lots of complaints and they may therefore get annoyed for this. In my opinion,    8     shopping online on that day brings consumers a lot of convenience, they should be     9    (care) and buy in the shop with a good reputation in case of     10    (cheat).
