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.

1. Passage 15 There is a commonly held myth that Einstein was an underachiever at school， but it really isn＇t true. While he may have had difficulties with languages， Einstein excelled in physics， mathematics and music. Einstein held many patents and was a keen inventor. While working at Swiss patent office in Bern he took it upon himself to write his own scientific papers in his spare time， mostly at weekends and in the evenings after work. 1905 was Einstein＇s miracle year. During this year he wrote three fundamental papers， any of which would have guaranteed him immortality in the world of physics. His first was on a new understanding of the structure of light. Einstein argued that light is composed of small particles of energy， called photons， as well as oscillating waves. The second paper built upon the theory of kinetics. Einstein explained how atoms were responsible for the buffeting of particles of material in suspension， like cigarette smoke suspended in air. This paper presented the first direct evidence for the existence of atoms， vindicating an idea that had been around for over 2000 years. His third paper of 1905 was ―On the Electrodynamics of Moving Bodies‖. Here Einstein derived the theory of ―special relativity‖. In a supplementary paper four months later， he formulated the famous equation， E=mc2， where mass and energy are equivalent， showing that a very small amount of mass converts to a huge amount of energy. This is the driving force behind atomic bombs， and all the stars in the Universe. According to the first paragraph， Einstein.
