The story is about a donkey falling into a well. When theowner decided to give him up and cover up the well with dirt，the donkey was very frightened at first， but he calmed downvery soon. With every shovel of dirt hitting his back， he shookthe dirt off and took a step up. Finally， he succeeded in gettingout of the well.

In the story， the donkey faces the trouble positively. Heeven considers it as a stepping stone. It is the positive attitudethat makes him succeed. In life， we should learn the optimisticattitude from the donkey. Faced with trouble， we should calmdown as soon as possible， and try to find effective ways to dealwith it.

Similarly， as students， when we come across somechallenges in study， we should keep positive and make effortsto solve them instead of escaping from them.

Hello， everyone！ Among all the travelers and adventurers，my favorite one is Marco Polo， a famous Italian traveler， whotraveled along the ancient Silk Road to China in the 13thcentury.

He traveled in China for 17 years， visiting many parts ofChina， and was amazed to find how beautiful and powerfulChina was. Although Marco Polo was not the only traveler whoset foot in China， what set him apart from the others was thathe introduced Chinese culture and scientific inventions to otherparts of the world.

In my opinion， Marco Polo is really a great traveler， whopromoted the exchange of different cultures and spread theseeds of civilization.
