During the “golden week” national holiday that began on October st,hundreds of thousands of sightseers flocked to Lijiang,a picturesque historic town in the south-western province of Yunnan. Among its    1     (attract)are the symbols printed beneath the Chinese characters on road signs and shop fronts (Starbucks included).They are Dongba pictographs,     2     ancient form of script(文字)that originated among the Naxi,a local ethnic group.It almost    3     (die) until about a decade ago,     4     local officials began to realize its value and covered the town with it.

Dongba was never    5     (wide)used by the Naxi,of whom there are about 300,000 8living in the Himalayan foothills near Lijiang. as well as in Tibet and Sichuan province. The pictographs, which evolved as early as the seventh century,     6     (develop) by shamans(巫师) of the Dongba faith, which has roots in Tibet.

Over 20,000 of these religious records survive. They provide rich insight into how Naxi people thought about war, geography, astronomy and agriculture. But they are extremely hard    7     (read).Linguists are helped by the area’s Dongbapriests(神职人员). There are about 600, most of them very old, including Yang Guoxing, who ran a school from 2010 to 2015 to teach Dongba to children    8     (live) in the mountains. When Mr Yang was growing up,“everyone was too busy farming to learn it. Now they are all busy soaking up the pop culture," he says.

Signs at bus stations in rural Yunnan encourage locals to use written and spoken Chinese. But the Naxi get off lightly compared    9     other ethnic minorities. Primary schools in Lijiang teach the Dongba script twice a week, as well as Naxi nursery rhymes.Li Dejing, head of the Dongba Culture Research Institute, says this is not just about keeping alive the pictographs,     10     letting children grasp “the very spirit of their own culture”.And this will also help tourism to develop in Lijiang.

The negative health effects of skimping (节省) on sleep during the week can't be reversed (扭转) by marathon weekend sleep sessions, according to     1     new study.

Despite complete     2     (free) to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained     3    (near) three pounds over two weeks. Meanwhile, they experienced metabolic disruption (代谢紊乱) that would increase     4     (they) risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of     5     (insufficiency) sleep, those gains     6     (wipe) out when people fell right back into their same sleep-deprived (睡眠不足) schedule the next Monday.

“If there     7     (be) benefits of catch-up (加紧弥补) sleep, they’re gone when you go back to your routine. It’s very short-lived.” said Kenneth Wright, director of the sleep and chronobiology laboratory at the University of Colorado at Boulder,     8     oversaw (监督) the work.

Wright said that the study suggests people should prioritize (优先处理) sleep-cutting out the optional “sleep stealers” such as     9     （watch）television shows or spending time on electronic devices. Even though people don’t have a choice about losing sleep due     10     child-care responsibilities or job schedules, they should think about prioritizing sleep in the same way they would do to a healthy diet or exercise.

A study,     1     (lead) by the University of St. Andrews, found a balanced and healthy lifestyle, including becoming fitter, having less stress and sleeping     2     (long) all gave skin a more healthy-looking colour.

Previous     3     (study) have linked improvements in skin colour to a good diet but the latest study also examined     4     relationship between general health and skin colour.

They measured skin colour with a device that recorded how a rainbow of colours was reflected from the skin and found that both high     5    (fit) and low body fat were associated with a higher skin yellowness.

The research team also assessed whether a change in health changed skin appearance. They     6     (follow) 59 students from sports clubs to measure the training effect     7     their skin.

They found those     8     became healthier or lost body fat showed an increase in skin yellowness. Scientists concluded that exercise and healthy eating were low-cost ways of improving your skin. Any effort     9     (improve) lifestyle would benefit the skin within a     10     (relative) short time.
