A recent survey has found that many people suffer from sleep problems. Some are     1     (able) to fall asleep, some wake up in the middle of the night, and others     2    (simple) do not get enough sleep. One of the reasons why people fail to get a good night’s sleep     3     (be) pressure from school or work. Noise pollution and light pollution in big cities may also contribute     4     sleep problems. In     5     short term, people with sleep problems often feel tired and have trouble concentrating. In the long term, they may be at increased risk of having a poor memory, being overweight and     6     (suffer) a heart attack. Sleep problems are especially dangerous for     7     (teenager). They are still growing and night is the time when     8     (they) bodies grow faster. Teenagers     9     do not sleep well may experience situations where body development slows down, and their health suffers.

So, if you have trouble getting a good night’s sleep, it might be time     10     (make) some changes in your lifestyle.

5 . To improve road safety and raise awareness among Russia’s notoriously (臭名昭著地) careless drivers, Russian police have tried to get drivers to slow down at zebra (斑马) crossings by having painted horses as zebras walk across on the busiest streets in some of the big cities.

The light grey horses, painted with black stripes (条纹), carried signs on their backs reading: “Careful, children are on their way to school.” The police sent the “zebras” to several different locations in the Russian capital, where officials in orange vests walked them over zebra crossings and handed out leaflets (传单) to passing drivers.

Some held up rainbow-coloured umbrellas over the painted animals to protect them from the rain. Russian roads are notoriously dangerous and drivers still rarely take steps to avoid pedestrians. Nearly half of all traffic accidents in the country’s big cities are caused by cars hitting pedestrians, and a third of those occur on crossings, according to traffic police figures published last month.

In the first six months of this year, 378 people were killed and more than 6, 600 injured on pedestrian crossings in Russia, according to police. In Moscow alone, 43 people were killed, including two children.

Though police officials said that only safe paint would be used on the animals, animal rights activists still disagreed with the idea, accusing the police of “treating animals like garbage”.

“Children understand that paints are bad for animals,” the Interfax news agency quoted president of Vita animal rights group Irina Novozhilova as saying.

Let’s hope this part of the campaign is over and animals are left out of future attempts to raise pedestrians’ awareness.

7 . In recent years, traditional Chinese culture and art has gained a foothold on short video platforms and attracted a large number of young followers thanks to the explosive growth of the short video industry. Relaxing, emotional and fragmented, these video contents perfectly match the demands of the users. With the application of new technologies such as social communication and immersive experiencing, short video platforms are seeing more users, becoming a shining spot of new Internet media.

Peking Opera was also well-received on short video platforms thanks to a series of AR effects. Users love to film clips with a set of virtual facial makeup, headwear and costumes. Statistics indicate that these effects were applied by more than 18 million users, most of whom were young people.

In addition to Chinese operas, intangible cultural heritage items, such as embroidery, paper-cutting, printing and dyeing, shadow play works, oiled paper umbrella making, and bamboo weaving are also actively promoted on short video platforms. In a word, short video platforms are becoming an important channel to display China’s intangible cultural heritage.

China is a big old country,     1     has a history of more than five thousand years. We are proud of     2     (it) culture and part of the culture even influences the world     3     (great), for example, the thought of Confucius. As Chinese economy develops very fast and plays     4     important role in the world, more and more     5     (foreign) learn Mandarin (普通话) in Confucius institutions.

But some day, they     9     (realize) it is wrong     10     (abandon) traditional culture.

10 . TikTok has pushed a new safety update to its app that allows parents to take more control of their teenager’s accounts, as social media companies come under increasing pressure to make their platforms safer for children.

The company said that its Family Pairing now enables parents to turn off comments on their children’s videos entirely or limit them to friends only. Parents whose accounts are linked to their kids will also be able to set their accounts to private ones, turn off the search function for content or users, and limit who can see which videos their children have liked.

The Family Pairing lets parents see how long their children are spending on TikTok each day and limit the content they can see.

TikTok allows children to register (注册) and create an account if they’re over the age of 13. All they need to do is provide their date of birth. However, because TikTok doesn’t require registrants (注册人) to prove their identities, some children under 13 have registered by lying about their age, according to U.K. regulator Ofcom (英国通信管理局)

Alexandra Evans, head of child safety public policy for TikTok in Europe, told CNBC that Family Pairing has “put itself in parents’ shoes”since it was launched. “If we’re thinking of it as a toolbox, we want to offer more tools,” she said on a video call ahead of the announcement.
