4. Passage 18 Students can travel in the United States without spending too much money if they follow these suggestions. A travel agent can give you information on special economy fares for trains， buses and planes. Think about hiking or biking for a part of your trip， too. You‘ll not only save money， but you‘ll also see a lot more of the country. Some students may want to travel by car. Be sure to think about going with other students — many colleges have ―ride boards‖ that list when and where other students plan to travel. Many radio stations provide the same sort of service — they announce who‘s driving where， when， how many riders they will take and what the expenses will be. There are many inexpensive， older hotels near bus or train stations. Check your travel guide for names of the best. Many parts of the country also have youth hostels where young people can stay for only a few dollars a night. You don‘t have to eat in restaurants all the time， but we don‘t recommend a diet of candy and cola， either. You can usually get a healthy， cheap breakfast in a restaurant. If the weather is warm， you can buy food in supermarkets or at roadside stands and have a picnic for lunch. For dinner you can get the names of good， cheap restaurants from travel guides or friends.

2. Passage 7 Greek soldiers sent messages by turning their shields toward the sun. The flashes reflected light could be seen several miles away. The enemy did not know what the flashes meant， but other Greek soldiers could understand the message. Roman soldiers in some places built long rows of signal towers. When they had a message to send， the soldiers shouted it from tower to tower. If there were enough towers and soldiers with loud voices， important news could be sent quickly over distance. In Africa， people learn to send messages by beating on a series of large drums. Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple， they could be sent at great speed for hundreds of miles. In the eighteenth century， a French engineer found a new way to send short messages. In this way， a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet. It was like spelling out words with flags and arms. Over a long period of time， people sent messages by all these different ways. However， not until the telephone was invented in America in the nineteenth century could people send speeches sounds over a great distance in just a few seconds. Which of the following statements is true?

A. 　Neither the Greek soldiers nor their enemy could understand the message.

B. 　African soldiers shouted from tower to tower to pass message.

C. 　Telephone was invented by a French engineer.

D. 　Only by using telephone could people send speech sounds quickly.

4. 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. A son is unwilling to work in his father‘s business mainly because( ).

A. 　 he wishes to make full use in school

B. 　 he wants to prove his independence

C. 　 he wishes to do the opposite of what his parents approve of

D. 　 he wants to show his love for his parents

1. Passage 5 Today anyone will accept money in exchange for goods and services. People use money to buy food， furniture， books， bicycles and hundreds of others they need or want. When they work， they usually get paid in money. Most of the money today is made of metal paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China， cloth and knives were used. In the Philippine Islands， rice was used as money. In parts of Africa， cattle were one of the earliest money. Other animals were used as money too. The first metal coins were made in China. They were round and had a square hole in the center. People strung them together and carried them from place to place. Different countries have used different metals and designs for their money. The first coins in England were made of tin. Sweden and Russia used copper to make their money. Later， other countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than paper money used today. Money has had an interesting history from the days of shell money until today. Which of the following can be cited as an example of the use of money in exchange for services?

A. 　To sell a bicycle for $20.

B. 　To get some money for old books at a garage sale.

C. 　To buy things you need or want.
