Therefore, the responsibility bestowed by the times falls on nobody but us youth. If we are intelligent, China will be intelligent; if we are wealthy, China will be wealthy; if we are strong, China will be strong; if we are independent, China will be independent; if we are free, China will be free; if we are progressive, China will be progressive; if we are superior to young Europeans,China will be superior to Europe; if we are the best in the world,China will be the best in the world.B. In ancient times those who wanted to learn would seek out a teacher, one who could propagate the doctrine, impart professional knowledge，and resolve doubts．C. Since no one is born omniscient，who can claim to have no doubts? If one has doubts and is not willing to learn from a teacheudly.r, his doubts will never be resolved． Anyone who was born before me and learned the doctrine before me is my teacher．Anyone who was born after me and learned the doctrine before me is also my teacher．Since what I desire to learn is the doctrine, why should I care whether he was born before or after me? Therefore，it does not matter whether a person is high or low in position, young or old in age．Where there is the doctrine, there is my teacher．D. The morning sun is rising in the sky, bright and brilliant;the Yellow River is running to the sea, mighty and magnificent.A hidden dragon leaps out of a deep pool and fishes flee;a tiger cub roars in the hollow valley and beasts creep;a proud eagle springs off the vast land and dust reelsExotic buds are bursting in the trees, pretty and vigorous;double-edged swords are sharpened on the stones, icy and glorious.E. The tradition of learning from the teacher has long been neglected． Thus it is difficult to find a person without any doubts at all．Ancient sages, who far surpassed us, even learned from their teachers．People today, who are far inferior to them, regard learning from the teacher as a disgrace．Thus, wise men become more wise and unlearned men become more foolish．This explains what makes a wise man and what makes a foolish man．F. Blue heaven over our heads, yellow earth below our feet,profound history in our hearts, and extended roads before our eyes,we look forward to our future as wide as ocean, great and grand.So majestic is our young China, forever with the universe;so robust are our Chinese youth, eternal with our motherland.G. The ancient sages did not limit themselves to particular teachers．Confucius had learned from people like Tanzi, Changhong, Shixiang, and Laodan, who were not as virtuous and talented as Confucius．Confucius said "If three men are walking together， one of them is bound to be good enough to be my teacher．"A student is not necessarily inferior to his teacher, nor does a teacher necessarily be more virtuous and talented than his student．The real fact is that one might have learned the doctrine earlier than the other, or might be a master in his own special field．
