[阅读理解]Several different stories are told about the origin of Saint Valentine’s Day. One story dates as far back as the days of Roman Empire. According to the story. Claudius, the Emperor of Rome, wanted to increase the size of the army. He knew that it would be easier to get young men who were not married to join the army; therefore, he made a rule that no young men could marry until he had served in the army for a number of years. A priest(man working in church) named Valentine broke the rule and secretly married a great number of young people. Finally, Claudius found out about Valentine and put the priest in prison, where he remained until his death on February 14. After his death, Valentine was made a saint(圣人) and the day of his death was named Saint Valentine’s Day----which is a time for people to send one another their greeting of many kinds.
