Its _______ Carmen has always been passionate about fitness and dance, having spent 15 years getting trained as a ballet dancer.

_______ she loved dancing, she never _______ pursuing dance as a career. Instead, she chose to study economics in Imperial College Business School and graduated with _______.

Because of this, she was _______ by a top consulting company in London. However, Carmen realized there had always been a _______ within her that she would make her mark in the field of fitness. Despite her strong belief, it was still a _______ decision to quit for passion. Thus, Carmen spent a long time _______ her options. Carmen eventually left her job, returned to Malaysia, and __________Rebarre.

But why barre? To Carmen, the __________ of barre is that there is no __________ to entry to barre; anyone can do it.

The Ganqiu Festival is one of the oldest traditional celebrations and social activities of the Miao ethnic group in China. It falls on the first day of “Liqiu”,     1     indicates the end of summer. Miao people     2     (settle) down in Huayuan County, Fenghuang County, Jishou County, Luxi County and several other counties in Hunan Province hold a series of grand     3     (ceremony) to celebrate the day. The festival is not only an opportunity for Miao people to celebrate a good harvest, but     4     important social occasion for young Miao men and women as well.

According to local tales, Miao people drove out demons (恶魔) from their lands and began planting rice to build up their homeland. And due to their hard work, they were blessed     5     a harvest every autumn. Since then, the festival has remained a celebration of their victory, an expression of their     6     (appreciate) for the harvest season, and a way to send blessings to others.

Having a long history, the Ganqiu Festival observes many customs     7     (pass) down from generation to generation.     8     (traditional), during the day, Miao people wear colorful costumes and gather for a feast featuring     9     (attract) shows and sports activities. The festival     10     (list) as national intangible cultural heritage in 2014 and later as UNESCO intangible cultural heritage in 2016.

4 . Researchers have designed a hand-held device that can obtain and change water molecules (分子) from the air into drinkable water using only surrounding sunlight as its energy source.

This atmospheric water harvester (大气层水分收集器) used an ultra-porous (超多孔的) material, known as a metal-organic framework (MOF). It can obtain water repeatedly in the hottest and driest place in North America, Death Valley National Park. The tests showed the device could provide clean water anywhere, addressing an urgent problem, as climate change speeds up drought conditions.

“Almost one-third of the world’s population lives in water-stressed areas. The UN predicts that almost 5 billion people on our planet will experience some kind of water stress for a significant part of the year 2050,”said Omar Yaghi. He is the Berkeley chemistry professor who invented MOFs and is leading this study. “It is very important to take advantage of a new source for water.”

Other kinds of materials, such as salts or hydrogels (水凝胶), cannot operate in extreme weather conditions in an energy-efficient manner. The new MOF-powered harvesters can be a powerful tool to address water shortage issues related to anything from drinking water to agriculture. This technology can also be used to obtain pure water in areas where water is plentiful but not clean.

It’s also extremely efficient at harvesting water, releasing 85 to 90 percent of the water it obtains. It harvested up to 285 grams of water per kilogram of the metal-organic framework in a day, the amount of a cup of water. It’s also smaller than the earlier type but it is even more energy-efficient. It produced 200 grams of clean water per square meter of water vapor, more than three times the water productivity rate of the earlier type.

There will likely be further developments in efficiency and size for this device. Yaghi said, “He can see one day the widespread adoption of household-based MOF-powered water harvesters and community-scale (社区规模的) water harvesters with the help of data science and machine learning. Those can be in kitchens or even next to air conditioners to supply homes with clean water for cooking and cleaning. And some companies are already working on this.”
