8 阅读理解。 Narcissus was a beautiful looking boy. He had long, flowing, blond hair, beautiful, bright, blue eyes and even, white teeth. Many young ladies fell in love with him including the nymph (女神): Echo. Nymphs were lively spirits who lived near streams and lakes and protected trees in the forest. Echo had upset the Queen of the Gods: Hera. As a punishment Hera made Echo unable to speak except to repeat the last three words of the person she was talking to. Poor Echo fell in love with Narcissus but could never tell him how she felt. Narcissus teased her and she ran away with tears pouring down her face. Aphrodite, the goddess of love saw what happened and decided to punish Narcissus. As he came to a pool of water Narcissus saw his reflection (影子) and fell in love with the vision he saw. It was of course his own reflection. Poor Narcissus watched his own reflection, but every time he tried to touch the face of the vision he loved it broke up on the shimmering surface of the water. Narcissus stopped eating, lost his beautiful looks and desired to get his love. In the end he anguished gradually and died. Aphrodite took pity on him and made a flower grow in his place on the bank of the lake. Narcissus flowers (水仙花) can be found to this day growing wherever you can find water and trees. 1.
