It was built over many centuries, starting more than 2,000 years ago. The main purpose of the canal was to transport goods like grain, silk, and tea from the south to the north of China. Ancient engineers did not have modern machines, so they used simple tools like shovels, picks, and baskets to dig the canal. One of their cleverest inventions was the canal lock. Locks solve the problem of different water levels. When a boat needs to go up a hill, it enters a lock. The gates close, and water flows into the lock to raise the boat to the next level. Then the gates open, and the boat continues its journey. Today, the Grand Canal is still used for transport, and it is also a popular tourist attraction. Many people take boat trips to enjoy the beautiful scenery along the canal. The Grand Canal is not just a waterway; it is a symbol of ancient Chinese engineering and wisdom. ( ) 1.

To stop boats from moving B. To help boats move up or down where water levels change C. To clean the water D. To make the water flow faster ( ) 4. What do people do along the Grand Canal today? A. Only use it for transport B. Only use it for fishing C. Use it for transport and tourism D. No one uses it anymore ( ) 5. Why is the Grand Canal called a symbol of ancient Chinese wisdom? A.
