Alice Thompson is a girl from Sydney, Australia. She had her first long     1     (distant) train ride at the age of 18. Together with a friend, she got     2     the famous Ghan train in Sydney and got off in Alice Springs. During the two days and nights, they ate meals     3     (cook) by experts and saw fields, desert and     4     (abandon) farms. In the daytime, Alice talked to other passengers and read some books. At night, she watched the stars in the sky     5     shone like diamonds.

Why is the train     6     (call) the Ghan? It is short for Afghanistan. A long time ago, Australians wanted to travel to the middle of their country, so they brought some     7     (train) camels from Afghanistan    8     (carry) food and other supplies, and returned with wool and other     9     (produce). They did that until     10     1920s, when the government built a new railway line and took the place of camels.

4 . Lost cities that have been found

In 2015, a team of explorers to Honduras in search of"the Lost City of the Monke God"led to the discovery of the White City. They found the ruins in the Mosquitia region of the Central American country which is known for poisonous snakes, vicious jaguars and deadly insects. It is believed that local people hid here when the Spanish conquerors(征服者) occupied their homeland in the16th century.

Modern researchers were teased by the ancient writings about the Egyptian cities Canopus and Heracleion- where Queen Cleopatra often visited. But the cities weren’t found until 1992, when a search in Alexandria waters found that the two cities had been flooded for centuries. Artifacts(史前器物) showed that the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt.

A Yale professor discovered "the Lost City in the Clouds"in 1911. A combination of palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rule. The city, which was abandoned in the 16th century for unknown reasons,was hidden by the local people from the Spanish conquerors for centuries keeping it so well preserved.

The ancient city of Troy in homer's The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about 5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.

Buried deep in the ruins of the Shang Dynasty,     1     (specific) in Anyang City of Henan Province, bones of the rhino (犀牛) were found.

A collection of archaeological evidence has confirmed the     2    (exist) of rhinos in ancient China. The animal    3    (distribute) across China’s Central Plains,     4     Chinese civilization originated.

Nevertheless, the rhino was no longer wandering in the region after the Han Dynasty. One explanation is that it was the colder climate of Northeast Asia that saw the creature    5    (appear) from the pages of history. However, Zhou Yu, the writer of History of Chinese Armor (盔甲), offered up    6     explanation: the crafting of armor.

Armor was originally made of bamboo but the material possessed limited    7    (defend) capabilities. Leather armor later became popular during the pre-Qin period. Zhou’s book    8    (read) that the rhino’s thick skin was a primary material for the creation of warriors’ armor. Many ancient accounts recorded the killing of rhinos and     9    (turn) their skin into protective covering. “The huge demand     10     rhino skins might have caused the animal’s disappearance or at least its migration from the Central Plains to the southwestern regions,” Zhou told Beijing Review.

Cholera used to be one of the most feared diseases in the world. In the early 19th century, when cholera     1     (break) out in Europe, John Snow became frustrated because no one knew how to prevent or treat cholera. However, he never lost his desire to destroy cholera once and for all. Snow subscribed     2     the theory that cholera was caused by an infection from germs in food or water. He suspected that the water pump was     3     (blame). Snow began by marking on a map the exact places     4     all those who died had lived. As     5     consequence, John Snow was able to announce that the pump water carried cholera germs.     6     (according), he had the handle of the pump     7     (remove) so that it could not be used. The truth was     8     there was a link between cases of cholera and the different water companies in London. The people who drank this water were much     9     (likely) to get cholera than those who drank pure or boiled water. Fortunately, we now know how to prevent cholera, thanks to the work of John Snow. Moreover, by     10    (use) maps and statistics, Snow transformed the way scientists study diseases. For this reason, Snow is considered the father of modern epidemiology.

9 . Have you ever wondered why people drive on a different side of the road? It might seem bizarre that U. K. Drivers stay on the left, but they’re not the only ones. Around 35 percent of the world population do the same, including people in Ireland, Japan, and some Caribbean islands.

Originally, almost everybody traveled on the left side of the road. However their way of transport was quite different from today: Think about four legs instead of four wheels. For Medieval swordsmen on horseback, it made sense to keep to the left to have their right arms closer to their enemies. Getting on or off was also easier from the left side of the horse, and safer done by the side of the road than in the center.

So why did people stop traveling on the left? Things changed in the late 1700s when large wagons (货车) pulled by several pairs of horses were used to transport farm products in France and the United States. The wagon driver sat behind the left horse, with his right arm free to use his whip to keep the horses moving. Since he was sitting on the left position, he wanted other wagons to pass on his left, so he kept to the right side of the road.

The British Government refused to give up their left-hand driving ways, and in 1773 introduced the General Highways Act, which encouraged driving on the left. This was later made law thanks to The Highway Act of 1835.

When Henry Ford showed his Model T in 1908, the driver’s seat was on the left, meaning that cars would have to drive on the right hand side of the road to allow front and back passengers to exit the car onto the roadside. However, British drivers remain on the left, and this is highly unlikely to change.
