1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

During China’s dynastic period, emperors planned the city of Beijing     1     arranged the residential areas according to social classes. The term “hutong”,     2     (original) meaning “water well" in Mongolian, appeared first during the Yuan Dynasty.

In the Ming Dynasty, the center was the Forbidden City,     3     (surround) in concentric (同心的) circles by the Inner City and Outer City. Citizens of higher social classes     4     (permit) to live closer to the center of the circles. The large siheyuan of these high-ranking officials and wealthy businessmen often     5     (feature) beautifully carved and painted roof beams and pillars (柱子). The hutongs they formed were     6     (order), lined by spacious homes and walled gardens. Farther from the center lived the commoners and laborers. Their siheyuan were far smaller in scale and       7     (simple) in design and decoration, and the hutongs were narrower.

Hutongs represent an important cultural element of the city of Beijing. Thanks to Beijing’s long history     8     the capital of China, almost every hutong has its stories, and some are even associated with historic     9     (event). In contrast to the court life and upper-class culture represented by the Forbidden City, the Summer Palace, and the Temple of Heaven, the hutongs reflect     10     culture of grassroots Beijingers.

2 . On January 22, a massive iceberg broke off from Antarctica’s (南极洲的) Brunt Ice Shelf. Scientists say the iceberg was expected to break off and the event isn’t connected to climate change. But the size of the iceberg is hard to imagine. This iceberg covers an area of about 600 square miles. That’s about twice the size of New York City.

Antarctica is covered with a layer of ice and snow that’s roughly 1.2 miles thick. As snowfalls, it piles up in the center of Antarctica in a huge layer of ice. Overtime, the weight of this ice and snow creates slowly moving rivers of ice called glaciers, which push out toward the sea.

When the glaciers reach these a，they slowly push out beyond the edge of the land, forming huge“ice shelves”. These are massive sections of ice that spread out over these a, floating on the water below. From time to time, the edges of the ice shelves break off. This is a natural process, called “calving (冰裂作用)”. Though calving events area normal part of the ice shelf in Antarctica, one expert describes huge calving events like this are “quite rare and exciting”.

This is the second time in two years that a huge iceberg has calved from the Brunt Ice Shelf. Though this calving event had nothing to do with the climate crisis, the world’s rising temperatures are definitely affecting Antarctica’s sea ice.

Unlike a nice shelf, sea ice isn’t attached to Antarctica’s land. It’s a layer of ice that floats on the surface of these a. The sea ice is there year-round. It grows larger in the cold winters, and smaller as it begins to melt in the summers. It’s now summer in Antarctica, and scientists say the sea ice is disappearing “unusually” rapidly. Last year, with temperatures warmer than normal, Antarctica set a record for the lowest amount of sea ice ever recorded. Scientists say Antarctica’s sea ice could set a new record low again this year.
