1. Passage 6 Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. A new community program called ―One On One‖ helps elementary students who‘ve fallen behind. Your education majors might be especially interested in it because it offers the opportunity to do some teaching， that is， tutoring in Math and English. You‘d have to volunteer two hours a week for one semester. You can choose help a child with Math， English， or both. Half-hour lesson are fine， so you could do a half hour of each subject two days a week. Professor Dodge will act as a mentor to the tutors ---- he‘ll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next week. I‘m sure you will enjoy this community service and you‘ll gain valuable experience at the same time. It looks good on your resume， too， showing that you‘ve had experience with children and that you care about your community. If you‘d like to sign up， or if you have any questions， stop by Professor Dodge‘s office this week. What is the purpose of the passage?

3. 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.
