On behalf of my school, I’d like to express our warm welcome. It’s a great privilege for me to accompany you on the visit to Taicang Harbour. The harbour witnessed the first voyage of Zheng He, one of China’s greatest explorers. A large fleet led by him navigated the blue seas, creating a splendid scene. Altogether, Zheng He made seven voyages to many countries and regions with his ships loaded with china, silk and tea as gifts. These voyages had a far-reaching impact on China and its neighbors, helping develop and strengthen mutual harmonious relations. May you have an unforgettable experience. ✎ Possible version✎  Columbus, an Italian explorer, was born in Italy, in 1451. As a child, he liked reading the book The Travels of Marco Polo, from which he learnt something about Eastern countries. So he wanted to travel there very much. In 1492, Columbus left Spain with about 87 sailors and started his voyage across the Atlantic Ocean. After more than two months at sea, he and his sailors finally reached the “New World”-America.        I admire Columbus very much. I think he must have had a lot of difficulties when he travelled, but he still carried on and finally discovered America. I will take him as an example and face the difficulties with courage.
