5. Passage 2 Man has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them， for example， was the great Italian artist， Leonardo Da Vinci. In the 16th century he made designs for machines that would fly， but they were never built. Throughout history， other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead， he fell to the ground and broke every bone of his body and rested in peace. The first real step took place in France， in 1783. Two brothers， the Montgolfiers， made a very large ―hot air balloon‖. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year， the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later， two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about. When did two Frenchmen rise above Paris?

5. Passage 8
Upon reaching an appropriate age (usually between 18 and 21 years)， children are encouraged， but not forced， to ―leave the nest‖ and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children， nor do children usually ask permission of their parents to get married. Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses through other friends， at jobs， and in organizations and religious institutions. Although children choose their own spouses， they still hope their parents will approve of their choices. In many families， parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father‘s business because of a fear that he will lose his autonomy in his father‘s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family. Coexisting with such love in the American family are cultural values of self – reliance and independence. The subject matter of this selection is( ).
