More than 2,500 tiny glass jars — each containing brightly colored powders — line the walls of a museum at Harvard University in Cambridge,Massachusetts.The pigment(颜料)samples make up the Forbes Pigment Collection.Art experts rely on the collection for an important scientific purpose — the colors act as standards to help them conserve and authenticate artists' paintings.
About a century ago,Edward Forbes,an art historian and art museum director at Harvard,noticed that the paint on some 14th century paintings in his museum's collection was deteriorating.To figure out how to save the paintings,he realized he would have to learn more about the materials used to make their paint.
Today,people can buy paint in every color of the rainbow.But variety in paint colors — and the ability to purchase those paints at a store — wasn't always possible.For centuries,artists collected and crushed(碾碎) everything from shells to rare stones to create the pigments that colored their artworks.They also used metal oxides(氧化物).
From 1910 to 1944,Forbes travelled the globe collecting powdered pigments.The samples helped art conservators understand how paint behaves on a chemical level.Paint might react to changes in light,temperature,or humidity,depending on its pigments' compositions.This can affect the colors of a painting over time or even cause paint to come off the painted surface.
Today,Narayan Khandekar,a senior conservation scientist at the Harvard Art Museums,is building on Forbes's work by adding newer,chemically made pigments to the collection.The collection also plays an important role in helping to stop counterfeiters(伪造者).In 2007,experts compared pigments from the collection with those from a painting thought to belong to abstract artist Jackson Pollock.Chemical analysis showed that a red pigment in the painting was actually made 20 years after the artist's death,proving that the artwork was a fake.
1.Which of the following can replace the underlined word “deteriorating” in Paragraph 2
A.Dropping off. B.Breaking down.
C.Cleared away. D.Gathered together.
2.What can be inferred about Edward Forbes
A.He was good at chemistry.
B.He collected many pigments.
C.He created pigments by himself.
D.He repaired a lot of old paintings.
3.What may be the best title for the text
A.Colorful Collection
B.Looking for Pigments
C.Every Pigment Has Its Own Story
D.Edward Forbes and His Collection

答案
一、用适当的关系词填空
1.that/which
2.when
3.that/which
4.why
5.where
6.that/which
7.where
8.where
二、阅读理解
1.B 词义猜测题。根据画线词后的句子“To figure out how to save the paintings”可推知,一些14世纪的绘画被损坏了,故此处的deteriorating可以用breaking down代替。
2.B 推理判断题。根据第四段中的“Forbes travelled the globe collecting powdered pigments”以及博物馆藏品的命名“Forbes Pigment Collection”可推知Forbes从全球各地收集了许多颜料。
3.A 标题归纳题。文章介绍了哈佛大学色素博物馆的来历及其作用。“Colorful collection”形象准确地概括了全文的主要内容,故A项为文章最佳标题。
三、七选五
1.who/that 考查定语从句。本句为定语从句,a friend为先行词,所填词在从句中作主语,指人,用who/that。
2.the 考查冠词。特指最后一班车,应该是the last train。
3.asleep 考查词性转换。此处的fall是连系动词,后接形容词作表语。fall asleep睡着了。
4.boarding 考查非谓语动词。此处的 after用作介词,所以后面接动名词作宾语。
5.earlier 考查比较级。根据上文可知,火车30分钟就到了,但作者睡了一个小时,因此那个男子才会说:“很抱歉,我没有早一点叫你。”所以要填比较级earlier。
6.Hearing 考查非谓语动词。I与hear之间是逻辑上的主动关系,故用现在分词作状语。
7.had spent 考查动词的时态。买火车票是发生在上车(I took the last train)之前,是过去的过去,要用过去完成时,故填had spent。
8.running 考查非谓语动词。介词 with的宾语是tears,run 与 tears 是主动关系,故用 running。
9.how 考查连词。句意:我问她我该怎么回报她。how怎样。
10.kindness 考查词性转换。the woman's后接名词。kindness n.友好的行为,好意。
