4. 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. The( )way of communication made use of visible signs.

A. 　French

B. 　 Roman

C. 　 African

D. 　 American

1. Passage 9 What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage. Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family， such as stairways and fire escapes， but not lifts. From the lower floors of the buildings， escaping through windows is possible， learn the best way of leaving by windows with the last chance of serious injury. The second floor window is usually not very high from the ground. An average person， hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course， it is safer to jump a short way than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leak into the room. On a second or third floor， the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury.
