Some scientists believe that the first plants to appear on Earth over 500 million years ago _____ looked purple, not green. Plants today are green because they use green chlorophyll(葉綠素)to produce energy. _____ these early plants probably used something called retinal, which is a dark purple color.

During the time of the Roman Empire(37BC—476AD), it was very difficult to make purple dye(染料). The dye came from sea snails(海螺). But 10, 000 dead sea snails_____ you just one gram(克) of purple dye...as well as a very bad smell! This _____ purple dye was called Tyrian purple, and it was the preferred _____ of emperors.

In 16thcentury England, purple was only _____ the king's family members. Queen Elizabeth I's clothes were purple, but ordinary people were not allowed to _____ the color.

In 1856, William Perkin, an 18yearold science student, noticed something strange while doing an experiment. The chemicals(化學(xué)藥品) he used to clean his instruments______ with the chemicals he used in his experiment and produced a bright purple color. This discovery led Perkin to start a company using this chemical mixture to make purple dye. The dye was much cheaper than seasnail dye. Thanks to Perkin, now anyone can afford to wear purple clothes.
