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.

3. Passage 1 The secret of being born lucky is a summer birthday， with May babies most likely to enjoy a lifetime‘s good fortune， according to a study of more than 40，000 people. The time of year at which you are born has an enduring influence on levels of optimism and self-reported luck， according to a research by British and Swedish scientists. May was the luckiest month in which to be born， with 50 percent of those born then considering themselves lucky， while October was the least lucky month， with just 43 percent claiming good fortune. The findings add to growing evidence that the phenomenon of luck is not all down to chance， but is affected by a person‘s general disposition. Other research has shown that whether people think themselves fortunate depends less on objective success than on having a ―glass half-full‖ or ―half-empty‖ approach to life. ―What we are seeing suggests that something is influencing how people perceive their luckiness. My hypothesis is that people create their own luck by traits such as optimism， that luck is a psychological phenomenon rather than a matter of blind chance，‖ said Professor Richard Wiseman， who led the research. The pattern of the result， with those born in spring and in summer reporting themselves luckier than those born in autumn or winter， could have two potential explanations， Professor Wiseman said. Which of the following statements is TRUE according to the passage?

A. 　Optimistic people tend to be luckier.

B. 　Devoted people tend to be luckier.

C. 　Objective success is more important than one‘s general disposition in feeling lucky.

D. 　People drinking more water tend to be luckier.
