英語演講稿：The Strength of trust
boys and girls，
good afternoon.
the content that i will give a lecture today is still about the subject that's unchanged since ancient times to now days， which is friendship. there have been thousands of explanations as for the word "friend". but i resolutely think that there is the best definition to explain it， which is trust. the story that i read recently makes my idea firm.
it happened in italy four centuries b.c.a young man named pi sia was sentenced to death， because of having offended the tyrant. pi sia was a filial son， and he asked to see his old mother before death. the king promised him ， but set down the condition that he must find another person to be in prison instead of him. the condition was so critical that it was almost impossible to be realized. but pi sia did find such a man， who was his friend named dameng. then pi sia went home to bid farewell with mother as he wished.
days passed quickly， and the term of imprisonment was near at hand， but pi sia had not turned back yet. most people ascertained that pi sia had deceived his friend.
it was a rainy day. when demeng was sent to the execution ground， all persons watching around laughed at him， but demeng himself was not worried at all. the rope was hanging on his neck， and just at the critical moment， one person ran quickly through the rain shouting loudly， "please wait， i'm coming!" it was pi sia who turned back in time.
this was the most moving curtain in the world. demeng took no care of himself in order to help his friend realize the duty， whose kind of spirit was moved one to tears. while pi sia did not hesitate to take life as the price for performing the promise， whose kind of courage was also rare to meet. my dear friends， do you know why demeng was so calm before death? the reason was that he believed his friend pi sia would not do such despicable thing as deceiving friends. this depended on the strength of trust.
this is a true story that is enough to shock everyone. especially to contemporary people who are surrounded by the benefit of themselves， it is more worth of pondering. friendship is the precious deposits of the human world and the coordinate of life， and it may keep the flowers of heart fresh and sweet forever. a true friend is large treasure of your whole life. when you are downhearted， they may encourage you to do all to catch up with the others， and when you are proud of yourself， they may remind you of keeping a clear head with sincere advice. however， in the modern society that regards the real interest as the most supreme power ， friendship becomes fragile and stingy .it is common that good friends known several years fall out to become enemies， and the friendship also becomes the chip of business...
