It is cold and windy in Moscow and snow is still on the ground.     1     none of that discourages visitors to the famous Moscow Zoo. They want to see the zoo’s two biggest stars: Ru Yi and Ding Ding.

During the summer, more than 30,000 visitors come here on     2     average day. Even during off-peak parts of the year, there is always a crowd in front of the Panda House. Since their arrival, the two pandas     3     (be) the stars of the Moscow Zoo,     4     (attract) thousands of visitors interested to see them,     5     are among the rarest animals in the world.

Pandas’ reproductive rate is extremely low. Females normally give birth to one or two cubs(幼崽). If twins are born, the mother may only raise the     6     (strong) of the cubs. A newborn panda baby only weighs about 0.1 percent of the     7     (weigh) of a fully grown panda, making its survival very difficult.

China and Russia agreed to let both pandas stay here     8     2034, part of a 15-year scientific program. Very soon, Ru Yi and Ding Ding who have been kept in separate suites will     9     (introduce) to each other. And the people of Moscow Zoo hope nature will take     10     (it) course and that baby pandas will be born here soon after.

Did you ever wish that you could foretell the future? Well, thousands of years ago, the people living in     1     is today Armenia thought they could. In the high mountains of the South Caucasus, archaeologists working at Gegharot have uncovered a fortune-telling center that     2     (date) back to the Late Bronze Age (1500-1200 B.C.). So far, three small shrines (圣地) have been unearthed, and each offers evidence of     3     (variety) methods local communities used in an attempt     4     (understand) the future.

The site of Gegharot is rather small in     5     (compare) with its neighbors. The Late Bronze Age in the South Caucasus was     6     era of centralization. Large new societies fought with one another     7     control of the region. The castle and western shrine at Gegharot are actually less than an acre in size. However, remains at the site are well preserved, thanks to destructive events that     8     (complete) destroyed it twice during its occupation.

The shrines at Gegharot offer archaeologists a rare glimpse into fortune-telling practices that would have been the closely     9     (guard) secrets. As work continues, archaeologists will learn more about these individuals and the techniques they used when they     10     (seek) to foretell the future.

In the Chinese language, Yaodong means “kiln cave”, named due to the building’s arched interior (拱形的内部), which looks like the inside of a kiln. These Yaodongs are     1     (common) found in the north central provinces of China such as Shanxi, Shaanxi, Gansu and Henan,    2     are located on the Loess Plateau (黄土高原).

Yaodongs can be divided into different types,     3     (depend) on the topography (地形) of the     4     (region) in which they were built. For instance，where hills are available, Yaodongs may be built into the slopes (斜坡), and a hill may contain several stories of Yaodongs.

The continuous use of Yaodongs on the Loess Plateau over the millennia can perhaps be attributed to their highly economical and efficient design. When     5     comes to building materials, only the local loess soil from the plateau is required for the building of Yaodongs. Additionally, the thick earthen walls are able to keep the interior of Yaodongs cool during the summer and warm during the winter.

In the last decade, the Yaodongs     6     (bring) to the attention of scientists and researchers. These traditional dwellings (住所) have been regarded     7     an example of sustainable design. It has been considered that Yaodongs are     8     reflection of a key traditional Chinese concept — the     9     (harmony) relationship between human beings and nature. Although Yaodongs may be a unique feature of the Loess Plateau，the idea     10     (reflect) in their construction is one that people today can bear in mind.
