The 11.11 Shopping Festival, as the event is now called, is also known in China as Singles Day. The shopping festival first started in 2009 and Alibaba said it chose the date because it was easy to remember. Last year, Tmall and Taobao together produced 19.1 billion in sales on that day, according to Alibaba. This year’s shopping festival kicked off with an even stronger start—sales hit 100 million yuan 55 seconds after midnight and reached 35 billion at the end of the day.
The shopping spree(狂欢) drew the attention of China’s leaders, as Premier Li Keqiang recently praised Alibaba’s founder, Jack Ma, for creating a day for consumption. China is trying to lead the country’s economy to a slower, more sustainable(可持续的)growth model based on domestic (国内的) consumption instead of investment and exports. Online shopping is no doubt a growth point that will release spending potential. China had 564 million regular Internet users by the end of last year. It has surpassed the US to become the world’s largest e-commerce market, with its online sales over 1 trillion US dollars (6 trillion yuan) by 2020.
“The real-time nature of online consumption attracts millions of people to spend money and enjoy life. E-commerce opens a new channel for China to encourage domestic demand,” Liu Yin, vice-president of the China International Electronic Commerce Center said. More importantly, it promotes employment and the logistics (物流) industry with its sales model of “online purchasing plus express delivery”, he added. Convenience, choice and low prices have increased online shopping, but there are still some problems with the one-day shopping spree.
Some online shops, driven by the huge profits, took this opportunity to play price tricks. They raised prices to twice those of the originals in the early October and then offered discounts on Nov 11. Many consumers, driven by the advantage they could take, just went along for the ride. “They spend lots of time online to check what to buy and are happy to get what they don’t really need at a lower price,” wrote Jia Ge, an Internet analyst, on his Sina weibo.

D.the development of logistic industry |

B.driven by the huge profits, many consumers bought what they didn’t really need |

【推荐1】A bright yellow “M” tells you that it’s a McDonald’s restaurant; we also associate the cheerful theme tune “I’m Lovin’ It” with the famous US fast food.
A brand’s music has a similar effect on its customers as its logo. “It appeals directly to the heart, where consumers’ decisions are really made,” wrote Marketing Week.
This is probably why companies from around the world have recently focused more on building a “sonic (声音的) identity”.
An example is the software company Tencent QQ. Since 2014, this Chinese company has been trying to trademark (申请商标权) its “Di-Di-Di-Di-Di-Di” notification sound. The trademark was finally approved on Nov 15, which means that Tencent’s “Di-Di-Di-Di-Di-Di” notification sound is now protected by law and can only be used by QQ.
Sound and music can also help tell stories. In Game of Thrones (《权力的游戏》) there are so many characters that it is difficult to memorize them all. So, they wrote melodies (旋律) specific to each family. The result is that characters do not only look familiar, but sound familiar too.
“I think a huge reason why sound inspires action is that, on an unconscious level, we are always listening,” Lauren Nagel, executive creative director at Pandora Media, told GeoMarketing. “You can close your eyes, but you can’t shut your ears.”
1. What is the influence of a brand’s music, according to Marketing Week?A.It creates a relaxing environment. |
B.It helps to get customers’ attention. |
C.It makes the brand better known. |
D.It encourages consumers to make quick decisions. |
A.how companies value their sounds and music |
B.the importance of trademark protection |
C.the lasting impact of a brand’s music |
D.what makes a good notification sound |
A.It helps to create more impressive scenes. |
B.It tells about the characters’ personalities. |
C.It suggests that important things are coming. |
D.It makes the characters easier to remember. |

【推荐1】In the 2021 Tokyo Olympic Games, the athletes were fighting hard to win glory for themselves and their country. Do you care about the gold medal count? Shouldn’t we just enjoy the game? Readers share their opinions.
George
The spirit of the Olympic Games is about sportsmanship and performing your personal best, which brings the whole world together under peace and competition. It was never purely about winning gold medals and dominance, as no single athlete can dominate (统治) the whole Olympic Games. The spirit of the Olympics also give an important message to the world that no single country should seek to dominate over others.
Eric
None of the athletes who fail to win a gold medal have anything to be ashamed of. If they win a medal, great! If they don’t, we know they did their best. One minute on stage, 10 years of practice off stage. The small medals contain their countless efforts. Gold, silver, bronze, even if they didn’t win any medal, we cheer for them and are proud of them. Go China!
Allende
The Chinese delegation has been put on too much pressure, which is unfair to all hard-working athletes. A gold medal is not everything. Think about those players who lost the gold but tried their best, most people do not show friendly sympathy to them, but even lightly blame them, and I was one of these people. I have to take this occasion to apologize for my behavior. Don’t create unreasonable pressure, you are not the one playing the game!

【推荐3】While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.
The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to complete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.
I watched the man dive off the block and knew right away that something was wrong. I’m not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.
But in those few awful strokes, the crowd had changed.
No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.
A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and he should have. Even though he was recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.
Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.
In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.
1. From the passage we can learn that the young man ________A.made his turn to start back pitifully. |
B.was skillful in freestyle in the game. |

D.was not capable enough to win the medal. |
