Question

【題目】 There are purple clothes, purple handbags, purple bicycles, purple furniture, even purple computers! Purple is very popular today. But a long time ago, purple was a very expensive and unusual color. Let’s take a look at the rich history of the color purple.

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

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

In 16th-century England, purple was only for the king’s family members. Queen Elizabeth I’s clothes were purple, but common people were not allowed (允許) to wear the color.

In 1856, William Perkin, an 18-year-old science student, noticed something strange while doing an experiment (實(shí)驗(yàn)). The chemicals he used to clean his instruments mixed 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 not expensive. Thanks to Perkin, now anyone can afford to wear purple.

【解析】

本文是一篇說(shuō)明文，通過(guò)對(duì)比和舉例，介紹了紫色的來(lái)歷和發(fā)展，說(shuō)明紫色曾經(jīng)是一種非常昂貴和不尋常的顏色，但在科學(xué)家Perkin的努力下，用兩種化學(xué)混合物制造紫色染料，終于使紫色成為當(dāng)今最流行的顏色之一。

【1】根據(jù)“Let’s take a look at the rich history of the color purple.”可知，此處表示“紫色的歷史”的含義。故填history。

【2】根據(jù)“But a long time ago, purple was a very expensive and unusual color.”可知，在很久以前，紫色是一種非常昂貴和不尋常的顏色�？捎�in the past表示“在過(guò)去”。故填past。

【3】根據(jù)“Purple is very popular today. But a long time ago, purple was a very expensive and unusual color.”可知，紫色現(xiàn)在是非常流行的顏色，用于“one of+可數(shù)名詞復(fù)數(shù)”結(jié)構(gòu)中。故填colours。

【4】根據(jù)“Some scientists believe that the first plants to appear on Earth over 500 million years ago probably looked purple”可知，5億年前地球上出現(xiàn)的第一批植物看起來(lái)是紫色的。故填purple。

【5】根據(jù)“Plants today are green because they use green chlorophyll (葉綠素) to produce energy. But these early plants probably used something called retinal, which is a dark purple color.”可知，過(guò)去的植物利用深紫色的視黃醛來(lái)產(chǎn)生能量，此處表示“產(chǎn)生”的含義，又因?yàn)闀r(shí)態(tài)是一般過(guò)去時(shí)，所以用其過(guò)去式形式。故填produced。

【6】根據(jù)“…it was very difficult to make purple dye (染料). The dye came from sea snail (海螺).”可知，此處表示“用海螺做紫色顏料”，可用“use sth to do sth”結(jié)構(gòu)表示，又因?yàn)闀r(shí)態(tài)是一般過(guò)去時(shí)，所以用其過(guò)去式形式。故填used。

【7】根據(jù)“…as well as a very bad smell!…and it was the preferred colour of emperors (皇帝).”可知，盡管海螺做的紫色顏料味道非常難聞，但是皇帝還是很喜歡，“盡管”可用although/though表示，用于句首需大寫(xiě)首字母。故填Although/Though。

【8】根據(jù)“but common people were not allowed (允許) to wear the color.”可知，16世紀(jì)普通人是不被允許穿紫色的。故填wear。

【9】根據(jù)“In 1856, William Perkin, an 18-year-old science student, noticed something strange while doing an experiment (實(shí)驗(yàn)).”可知，在做實(shí)驗(yàn)時(shí)發(fā)現(xiàn)有奇怪的事情發(fā)生，可用“happen”表示，又因?yàn)闀r(shí)態(tài)是一般過(guò)去時(shí)，所以用其過(guò)去式形式。故填happened。

【10】根據(jù)“This discovery led Perkin to start a company using this chemical mixture to make purple dye. The dye was not expensive.”可知，使用化學(xué)混合物來(lái)制造紫色染料不昂貴，也就是比海螺做紫色染料便宜很多，又因?yàn)榫渲杏斜容^級(jí)提示詞than，所以用其形容詞比較級(jí)形式。故填cheaper。
