Now Zack is bringing the broadcast from the largest museum on Earth—the Louvre,    1    (vivid) showing us some of the Louvre’s most amazing treasures.

    2    the top of these stone stairs is the Winged Victory of Samothrace. It looks like she has just    3     (fly) down out of the sky and is standing on a ship. Her head and arms are missing, but you can imagine her    4     (hold) her arms up high, celebrating the result of an ancient battle. Then he guides us to see the painting Mona Lisa.

    5     (protect) by glass, it looks smaller than we would expect. When you look into her eyes, she seems to have a mind     6    her own. Finally, the self-portrait of Rembrandt,     7    is one of history’s greatest artists, is shown to us. It     8    (paint) by Rembrandt himself about 400 years ago. Throughout his life, he made over 90 self-portraits. However, no one really knows the reasons.

In total there are about 35,000 works currently     9    (display) in the Louvre and it would take a lifetime to see everything. Zack recommends the fantastic place and hopes that we can visit it one day     10    (feel) the power of these great works of art for ourselves.

A skywell, or “tian jing” in Chinese, is a typical feature of a traditional home in Southern and Eastern China. They are commonly seen in homes     1     (date) to the Ming and Qing dynasties, which     2     (design) to house different generations of relatives. Despite their varied sizes and designs, these skywells are typically square and located in     3     heart of the house. They serve to allow in light, enhance airflow, and harvest rainwater.

Since decades ago, the government     4     (advocate) green buildings, promoting environmentally-friendly practice. The increased interest towards traditional Chinese architecture is leading to the restoration of historic buildings with skywells     5     modern use. Architects are also looking towards the principles behind skywells while designing new buildings     6     (save) energy. The Dongguan TBA Tower in Guangdong Province, for example, brings natural airflows into every floor with internal “windpipes”    7     function in a similar way to skywells. The aim is to keep the building's temperature     8     (comfort) in all seasons, using only natural airflow.

The fact that skywells still exist today shows     9     clever ancient builders were in using nature's elements to create energy-sufficient and sustainable living spaces. These timeless architectural     10     (wonder) continue to inspire architects in their efforts to find green solutions for cooling homes and buildings.
