【简答题】
His parents sent him to private teachers. Alfred was a very good student. When he was seventeen, he left Russia for Paris to study chemistry for a year. Then he went to the United States. He studied in the United States for four years. Alfred studied very hard and by the time he was twenty, he was already a very skillful chemist. Alfred was very good at learning languages, too. He could speak Swedish, Russian, German, French and English. Later he returned to Russia. At that time, his father’s factory had some difficulties and it failed in the end. His family became very poor and most of the family members had to go back to Sweden in 1859. When he came back from Russia, Alfred began his own study in his father’s lab. He invented dynamite. That was his greatest achievement. He hoped that people could use it for mining and road building. Alfred became very rich for his invention. But Alfred’s main concern was never with making money. Although he was very rich, he led a simple life until his death. He didn’t care about being famous either. From his youth, Alfred was seldom happy and he never married. He came to care deeply about the whole of mankind. He was always good to the poor. His greatest wish was to see an end to wars, and peace between nations. Alfred Nobel died in Italy in 1896. According to his will, the Nobel Prize was founded. He left money to give prizes for outstanding work in physics, chemistry, physiology and medicine, literature, and peace. And now Alfred Nobel is known all over the world and he is remembered and respected long after his death. 3.What was Alfred Nobel more concern about? Alfred Nobel was a great Swedish scientist and inventor. He was born in Stockholm on October 21,1833. When he was nine years old, he moved to Russia with his parents. His father had a mine there and made a lot of money.
