五、完形填空。
There are purple clothes, purple handbags, purple bicycles, purple furniture, and even purple computers! So purple is one of the most 1 colours today. But in the past, purple was a very expensive and unusual colour. Let's take a look at the rich 2 of the colour purple.
Some scientists believe that the first plants to appear on the earth over 500 million years ago 3 looked purple, not green. Plants today are green because 4 use green chlorophyll (叶绿素) to produce energy. 5 these early plants probably used something called retinene (视黄醛), which is a dark purple colour.
During the time of the Roman Empire, it was very 6 to make purple dye(染料). The dye came from sea snails(海螺). But 10,000 dead sea snails 7 you just one gram(克) of purple dye as well as a very bad smell! This 8 purple dye was called Tyrian purple, and it was the preferred 9 of emperors.
In 16th-century Britain, purple was 10 for the king's family members. Queen Elizabeth I's clothes were purple, but ordinary people were not allowed to 11 the colour.
In 1856, William Perkin, an 18-year-old 12 student, noticed something strange while doing an experiment(实验). The chemicals(化学药品) he used to clean his instruments 13 with the chemicals he used in his experiment and produced a bright purple colour. This 14 led Perkin to start a company using this chemical mixture to make purple dye. The dye was much 15 than sea-snail dye. Thanks to Perkin, now anyone can afford to wear purple clothes.

答案： 1. B 【点拨】peaceful 和平的；popular 流行的；exciting 令人兴奋的；serious 严重的，严肃的。根据上文“There are purple clothes, purple handbags, purple bicycles...”可知，紫色现在很流行。故选 B。2. A 【点拨】history 历史；style 方式，样式；research 研究；product 产品。根据下文内容可知，本文主要介绍紫色的历史。故选 A。3. D 【点拨】gradually 逐渐地；especially 特别；exactly 恰恰，确切地；probably 可能。根据上下文可知，并没有确切的证据表明第一批植物是紫色的，此处只是推测。故选 D。4.
