1、Passage 18Students 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.

1、Passage 7Greek 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.
