1 . A perfectly preserved wreck (沉船) that has lain unnoticed in the icy Baltic Sea for over 500 years has finally been confirmed. The European ship was first observed in 2009, when a sonar(声呐) exploration by the Swedish Maritime Administration (SMA) indicated a large object in the area. However, it was not until early 2019 that researchers from Soton and MMT found evidence of the sunken ship using underwater robotic cameras.
When the team observed the pictures of the 60-foot-long shipwreck, they were surprised to discover it was 99 percent complete. The scientists considered that the wreck's good condition is due to its place in the Baltic Seabed, where the oxygen levels are low. Oxygen is key to most ocean life's survival. Therefore, such an environment where the shipwreck stays reduces or completely removes the creatures that feed on rotting wood.
So although this ship is contemporary to the times of Christopher Columbus, it shows a remarkable level of preservation after 500 years at the bottom of the sea. Dr. Pacheco-Ruiz, who led the MMT effort, said,“It's almost like it sank yesterday. It's a truly astonishing sight."
The scientists are unsure what let the ship sink. However, the ship's guns, which are in their"ready to fire" positions, indicate it may have been the victim of a naval battle. Since the ship dates back to the early 16th century, historians predict it may have sunk during Sweden's three year independence war with its Danish rulers between 1521 and 1523. Alternatively, it could also have been involved in the border dispute (争端) between Russia and Sweden from 1554 to 1557.
The ship is by far the best-preserved shipwreck ever found from the Age of Exploration, when Europeans explored the world by sea.
What's more exciting is that the ship is similar to the Pinta and La Nina, which Comlubus famously sailed toward North America. The scientists, who continue to observe the shipwreck hope the boat's design will expose some of the technologies available to the Italian explorer during his 1492 voyage of discovery.

3 . China is a country of many resources. Among its resources are many great rivers, which provide useful transport routes. Water transport is an efficient way to carry heavy loads, such as grain. In ancient times, a waterway was needed between China’s rich farmlands and the capital city. This need inspired engineers to build a canal. According to writings by the ancient thinker Confucius, work on a canal linking the Yangze River with the city of Huai-in began about 486 B.C. For many centuries afterward, Chinese emperors worked on extending this ancient canal.
This canal is now known as China’s Grand Canal. One thousand years after the original canal was begun, it was in extreme need of repair. This was in the year 607, during the Sui Dynasty. By 610 the emperor had had the canal extended. The Grand Canal formed a northeast-southwest link between the Yellow River in the north and the Huai River in the south. The canal remained the main waterway in this part of China for the next five hundred years.
In the thirteenth century, the Mongols had conquered China. The Yuan Dynasty established Beijing as the capital. The city’s growing population needed food, so a new canal was built to extend shipping. Building this part of the Grand Canal required enormous effort and cost. Neither the first attempt nor the second one was successful, so the builders chose another route. Finally this link in the Grand Canal was finished.
By the time of the Ming Dynasty, the Grand Canal had six sections. These were busy with goods until the nineteenth century. Then a series of severe floods struck China. Parts of the Grand Canal were badly damaged. By 1868 it had been largely abandoned as a means of northern route.
The Grand Canal was mostly restored in the twentieth century. It was widened and deepened, and a new section was constructed. Today the canal, which is about 1,200 miles in length, has new locks(运河的水闸). It is busy with ships and barges(驳船) carrying goods to and from cities along its banks.
