Known as the roof of the world, the Tibet Autonomous Region has witnessed steady progress in economic and    1    (society) development.

To promote    2    (it) splendid natural scenery and rich cultural heritage,    3    5th China Xizang Tourism and Culture Expo was held from June 16 to 18 in Lhasa, the capital city of Tibet and was attended by 612 companies from home and abroad. Xizang is the name of Tibet in Chinese.

“This international tourism and cultural expo aims to build a professional and international exhibition platform to showcase the    4    (beautiful) of Tibet’s ecology, culture, history and the new achievements of socialism modernization of the region,” Hu Heping, minister of culture and tourism, said when addressing the opening ceremony of the expo.

All are along the national highway G219, the    8    (long) such route in the country,    9    covers more than 10,000 kilometers.

Tibet welcomed 288.4 million visitors from all over the world from 2012 to 2022,    10    (generate ) tourism revenue of nearly 375.3 billion yuan.

The Lights of Aurora

On the night of 2 September1859, the dark sky over Europe and North America was suddenly full of light! The light did no come from the sun or the moon and it had a strange colour. The light moved across the sky,     1     (come) and going, like clouds in a strong wind in the United States, a man in Boston was using the telegraph to speak to a man in Portand 160km away. They both turned off the electricity for the telegraph, but     2     could still speak to each other for the next two hours. The electricity was coming from the light in the sky. How was this possible? And what was the light in the sky?

The light is called the aurora. Usually, you can see it only at the very north of the earth,     3     it is called aurora borealis or Northerm Lights, or at the very south, where it is the aurora australis or Southern Lights. But in 1859, something happened in the sun — a very large storm — and it moved the aurora across the middle of the earth. We do not think that his ever happened before 1859, and we know that it     4     (not happen) since then.

Why does the aurora happen? And why can we only see it at the top or bottom of the earth? The aurora is made by something     5     (call) the ‘solar wind’( wind from the sun). We cannot see this wind, or touch it. It is a wind of particles that travel away from the sun at the time at about 400 kilometers a second. Most of the particles never touch the earth. The earth has a kind of ‘wall’ around it that defends it     6     these particles. This wall is called the earth’s magnetic field, and it pushes the particles away on either side. But the earth's magnetic field has two “windows” in it: the magnetic north, and the magnetic south. At these places. the earth’s magnetic field turns down into the earth. And some of the particles from the solar wind come through these magnetic ‘windows’. These solar particles crash is to the particles that are already in our sky. And     7     this happens, we see the beautiful lines or clouds of light of the aurora.

Alaska is a good place     8     (see) the auurora borealis, and you can also go to places like Iceland, Siberia, the north of Greenland, Norway, Sweden, and Scotland to see the aurora australis, go to the south of Australia, Tasmania, or New Zealand.

People travel thousands of kilometers to see the aurora, and they can never be sure     9     it will happen. But     10     do see it says that they will never forget it.

The Mystery is No Mystery

The area of ocean between Florida, Puerto Rico, and Bermuda, known as the Bermuda Triangle, is the source of much mystery. Over the centuries, reports of ships and planes disappearing     1     a trace have seized the public attention, leading the zone     2     (nickname) “The Devil’s Triangle.” Suggested causes for these mysterious disappearances range front supernatural powers to underwater alien bases. However, there is a more basic question to ask: Do more craft really disappear in the Bermuda Triangle than in any similarly trafficked area? The answer,     3     it turns out, is no.

The Bermuda Triangle covers a vast 700,000 square-kilometer swathe of ocean. Close to the equator(赤道)and near the United States, it is a particularly busy patch of sea with heavy traffic. According to Lloyd’s of London and the U. S. Coast Guard,     4     you were to compare the number of disappearances to the large quantity of ships and planes that have passed through the Bermuda Triangle, you would find that there     5     (be) nothing out of the ordinary about the area.

These days, new theories are being put forward, with a bit of scientific truth to them. Some have attributed Bermuda Triangle disappearances to explosive releases of methane (甲烷) gas,     6     (trap) as methane hydrate inside water molecules beneath the cold seabed of the deep ocean. Such blowouts could potentially release a giant amount of gas that could cause the sea to bubble like it was boiling, which could possibly sink ships because the resulting bubbles would be much     7     (thick) than the water on which large ships normally float. The gas could also rise into the sky,     8     (produce) a mixture of five to 15 percent methane which could explode on contact with the engine exhaust of a hot airplane.

The only problem with this theory is that scientists won’t be able to tell with much certainty if this is a factor       9     the ocean floor is mapped in greater detail. It remains to be seen     10     they will succeed in their attempt to clear up the Bermuda Triangle “mystery” this time around.

China has many famed explorers. There was Zhang Qian,     1     traveled into Central Asia,     2     (open) corridors of trade that became the Silk Road. Zheng He was a great mariner in the 15th century. Yet these voyages     3     (undertake) under the direction of governments Xu Xiake was different.

Born in 1587, Xu Xiake grew up in a rich family. Yet he rejected the     4     （comfort) life to travel the lost world of imperial China. As one of the greatest land explorers, Xu Xiake is said     5     (travel) thousands of miles of Chinese mountains and rivers on foot in his lifetime. The written work of Xu Xiake's travel records and diaries contains some 404, 000 Chinese characters,     6     enormous work for a single author of his time. It mixes     7     (detail) of geography, botany and local history with the ratings of the Ming Dynasty lodgings (住宿).

“On the surface, Xu's travel can neither be classified as great affairs of state     8     great undertakings that changed the course of history.” writes the cultural historian Zheng Peikai. “Xu traveled to satisfy his own     9    (curious) — he traveled for the sake of traveling.”

Xu Xiake traveled across China for 34 years. Perhaps his     10    (great) journey was his last. At age 50, he traveled to the tropical frontiers of Yunnan. Hundreds of years later, we follow. Naturally, he is the father of Chinese backpacking.

Heatable Brick Beds Warm NE China Homes

In northeast China’s chilly winter, getting into a warm bed is made possible by an ancient heatable brick bed that could date back more than two thousand years     1     is still widely used today. These beds not only bring warmth to local residents, but also continue the folk culture of northeast China.

The bed is made of bricks or other forms of fired clay with     2    width of about1.7 m to 2.3 m and a length that can be determined according to the length of the bedroom. It uses a ducted heating system similar to the Roman hypocaust,     3    (compose) of a stove, a bed and a chimney. The stove     4    (use) to burn firewood. Smoke and heat generated by burning firewood pass through an internal hollow and curved flue system to heat the bed above. Smoke is eventually discharged outward through the chimney. The bed retains heat well,     5    enables people     6    (have) a comfortable sleeping environment in the cold winter. In addition,     7    (sleep) on the heatable brick bed for a prolonged period is good for the blood     8    (circulate) and metabolism of the body, and can relieve some diseases such as arthritis and waist and leg pain.

The heatable brick bed is not only used as a bed, but also a living area for the family. People     9    (routine) have their meals and family     10    (gathering) on the bed in cold winters. The bed is a symbol of home that embodies the emotion and love they feel towards their families.

Pico Island, the second largest of the volcano-born Azores, is one of the most hard-won wine regions in the world. By the 19th century, Pico’s wine industry was at its peak,     1     (produce) three native white grape varietals: arinto dos Azores, verdelho and terrantez do Pico. But it wasn’t long before disease and desertification     2     (destroy) most of the island’s vineyards, nearly putting an end to its wine production. But some of Pico’s winemakers regrouped, centering their operations around the village of Criacao Velha,     3     high-quality grapes could still be grown.     4     only around 10 percent of Pico’s original vineyards have been restored (恢复), the appellation of origin has earned some of the country’s top wine honors.

    1     (locate) in the northeast of the Tibetan Highland, Qinghai Lake is usually No. 1 on “Most Beautiful Lakes in China” list. It has very different scenery in different seasons. In spring, the surrounding mountains and wetlands take on a fresh green look with     2    (colour) flowers and white snow. In summer and autumn, the lake     3     (decorate) with golden clothing, as thousands of hectares (公顷) of rape flowers spread out from Qinghai Lake’s shores. In winter, snow and ice cover the surface of the lake, and the lake becomes quiet.

Ink as one of the Four Treasures of the Study (brush, ink, paper and inkstone), is a    1     (necessary) in Chinese painting and calligraphy. Ink is     2     (typical) produced from an ink stick with a little water. Ink stick, the solid form of ink, can last much longer than the liquid variety and is easier     3     (transport). The most famous ink sticks in China are the Hui Ink Sticks produced in Anhui Province. The Hui Ink Sticks use pine wood     4     its main raw ingredient,     5     is then mixed with another about 20 different materials. The manufacturing procedure includes lighting the smoke, blending the materials together, pressing the ink sticks, drying by airing, filling the margin     6     boxing them up. The ink produced from these sticks is shiny black. For centuries, the Hui Ink Sticks     7     (produce) through the traditional methods.     8     simple and single, ink sticks are essential in Chinese calligraphy and painting,     9     (present) the splendid artistic conceptions to people. What’s more, ink sticks make it possible that modern people today still can appreciate the masterpieces     10     (create) tens of centuries ago.

New York City is a city that     1     (lie) at the mouth of the Hudson River, southeastern New York State. It is     2     (official) called the City of New York. The city has five parts: Manhattan, Brooklyn, the Bronx, Queens, and Staten Island — each having its own lifestyle.     3     (move) from one city to the next may be like passing from one country to     4    .

For the past two     5     (century), New York City has been the largest and     6     (busy) American city. Over half the people and goods that ever entered the U.S. in the past came through its port (港口). New York City means     7     (possible) because it is always on its way to something better. However, it has also become a goal for international terrorism (恐怖主义). The World Trade Center,     8     had been the most important symbol of the city for 30 years,     9     (attack) on September 11, 2001. Whatever happens, New York City is a place that provides people     10     all kinds of food, languages, and experiences.

In ancient times, Zhenjiang City, Jiangsu Province, in Eastern China was called Jing kou.    1     (locate) at the golden cross of the Yangtze River and the Beijing-Hangzhou Grand Canal, it is a place of     2     (strategy) importance.

The upper reaches of the Yangtze River deposit a lot of silt (淤泥) here,     3    has gradually built up into a small island in the river.

There are three beautiful mountains here—Jinshan Mountain, Beigu Mountain and Jiaoshan Mountain, which are     4     (close) connected with the Yangtze River and are called the Three Mountains of Jingkou.

Jinshan mountain is only 42 meters above sealevel.    5    Jinshan mountain is said to be on the Yangtze River, because the rivers course has moved to the north, JinShan is now some distance away from the Yangtze.

Beigu Mountain, 10 meters     6     (high) than Jinshan Mountain, is just beside the Yangtze River. From here, Jinshan Mountain can     7     (see) in the west and Jiaoshan Mountain in the east. Around the foot of the mountain     8     (flow) the mighty river.

Jiaoshan, the highest of the three,     9    an altitude of 70.7 meters and an area of 38 hectares, is located in the Yangtze River, surrounded by water. Encircled by the green waves, the green mountain looks like a piece of jade     10     (float) on the river.
