The national flag as we know it today is in no way a primitive artifact. It is, rather, the product of thousands of years' development. Historians believe that it had two major ancestors, of which the earlier served to show wind direction.
Early human beings used very fragile houses and boats. Often strong winds would tear roofs from houses or cause high waves that endangered travelers. People's food supplies were similarly vulnerable. Even after they had learned how to plant grains, they still, needed help from nature to ensure good harvests. Therefore they feared and depended on the power of the wind, which could bring warmth from one direction and cold from another.
Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods, such as watching the rising of smoke from a fire. The connection of the flag with heavenly power was therefore reasonable. Early human societies began to fix long pieces of cloth to the tops of totems before carrying them into battle. They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves.
These flags developed very slowly into modem flags. The first known flag of a nation or a ruler was unmarked: The king of China around 1000 B. C. was known to have a white flag carried ahead of him. This practice might have been learned from Egyptians even further in the past, but it was from China that it spread over trade routes through India, then across Arab lands, and finally to Europe, where it met up with the other ancestor of the national flag.

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Do you want to live forever？ By the year 2050, you might actually get your wish — providing you are willing to leave your biological body and take up residence in silicon circuits. But long before then, perhaps as early as 2008, less radical measures will begin offering a semblance (外表，伪装) of immortality.
Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, plus all that you say and write, can be recorded analyzed and automatically indexed, and added to your personal chronicles. By the 2030s, it may be possible to capture your nervous system's electrical activities, which would also preserve your thoughts and emotions. Researchers at the Laboratories of British Telecommunications have defined this concept as Soul Catcher.
Small electronic equipment will pave the way for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro - sensors under your scalp and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
At first, the Soul Catcher's companion system — the Soul Reader — might have trouble copying your thought in complete details. Even in 2030, we may still be struggling to understand the brain's internal workings, so reading your thoughts and interpreting your emotions might not be possible. But these signals could be conserved for the day when they can be transferred to silicon circuits to rejuvenate minds as everlasting entities. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.
For people who chose not to live in silicon, virtual immortality could still ease the sense of futility (无用) that now haunts many people. Individuals would know their lives would not be forgotten, but would be preserved as a thread in a multimedia quilt that keeps a permanent record of the human race. And future generations would have a much fuller understanding of the past. History would not be dominated by just the rich and powerful, Hollywood stars, and a few elite thinkers.
The main idea of this passage is that ______ .
A．human beings long for an immortal life
B．people can live immortally as technology develops
C．there are many difficulties in making the Soul Catcher
D．the invention of Soul Catcher has great significance
