23. Listening text: (Part 1) Many great poets have written about the beauty and dangers of the seas and oceans. In the 18th century, the English poet Samuel Taylor Coleridge wrote a poem called”The Rime of the Ancient Mariner”. In the poem, a mysterious guest tells a strange story to the people at a wedding. He begins his story by describing how a ship sets out to sea. One day, one of the sailors, or mariners. Shoots a bird that flies above the ship. When the other mariners see what he has done, they are

24. frightened and angry. The bird he has killed Is a bird that brings good luck to the ship. By killing the bird, the mariner has brought bad luck and death to the sailors. Soon, things turn bad. The wind dies down and the sailors are hungry and thirsty. There is water all around them, but they can’t drink it because it is too salty. “Water,water everywhere, nor any drop to drink.” The mariners are so thirty, hungry, and frightened that they begin to imagine things: they think they see monsters walking on the water.

25. Listening text: (Part 2) In the poem, two gods argue over what should happen to the ship and the mariners. Finally they decide that all must die---except the mariner who shot the bird. He must live through it all and will pay by having to tell the story to all the people he meets the rest of his life. On the ship the frightened mariner watches as the other sailors fall down dead on the ship’s deck. Left alone on the ship, drifting on the ocean, the mariner suffers from loneliness and fear.

26. Alone, alone,all, all alone, Alone on a wide wide sea! When the mariner is rescued at last, he must walk around and tell his story. This is what the guest tells the people at the wedding. His story told, the ancient mariner says farewell and asks them to learn from his sufferings.

27. Reflection What do you learn from the story? Everything existing in the world has their own certain values, we should understand and respect them.
