Ex6: read the passage and answer the questions
Van An was born in 1292 and died in 1370. From his childhood, he was famous for his intelligence. He did not have the dream of taking part in exams to become mandarins like other students. Chu Van An stayed at home and taught himself by reading books, and opened schools. His school quickly became famous in the region and many students from other places went there to study. Emperor Tran Minh Tong invited Chu Van An to be the principal of the Imperial Academy to teach his crown prince and other students to become talented people for the country. In 1359, Emperor Tran Minh Tong gave his crown to his son, Tran Hien Tong, who was also a student of Chu Van An. Under the regime of Emperor Tran Hien Tong, the court and the country were peaceful. However, this period lasted only for 12 years. Then Emperor Tran Hien Tong died, and Tran Du Tong inherited the crown. The social situation became complicated, the people were very poor and many good people were killed. Chu Van An bravely submitted a petition which requested the Emperor to behead 7 perfidious mandarins, so it was called Seven Beheaded Petition” (That Tram So). “Seven Beheaded Petition” became the symbol of the courageous attitude of the real intellectuals, and of Chu Van An's spirit.
