Questions are based on the following passage.
Artificial flowers are used for scientific as well as for decorative purpose. They are made from a variety of materials, such as silk and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure.
The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. The lifesize models include 847 species, with remarkably accurate anatomical sections and enlarged flower parts. They are made entirely of glass, often reinforced internally with a wire support.
The models in colored glass are the work of two artist-naturalists, Leopold Blaschka and his son Rudolph who made them from 1887 through 1936. Their lineage of jewelers and glassmakers traces as far back as the 15th century. The parts were shaped after the glass was softened by heat. Some models were blown. Colored glass was used for many, others were “cold-painted” with a thin wash of colored ground glass or metal oxides and heated until the material fused to the model.
Since the glass flowers are always in bloom, tropical and temperate species may be studied year-round. The gallery is open during regular museum hours and is included in the general admission fee.
The museum recently installed several Blaschka glass models from the ware collection which have not been seen at Harvard for decades. You can even see amazingly realistic models of apple and apricot plants illustrating some of the diseases affecting fruits of the Rosaceae family. Other newly installed models illustrate insect pollination, displaying bees enlarged to five inches in size to show pollination techniques.
The intention of the collection was to have it represent at least one member of each flower family native to the United States. Harvard Professor George Lincoln Goodale, founder of the Botanical Museum, wanted life-like representatives of the plant kingdom for teaching botany. At the time only crude papier-mache or wax models were available. Mrs.Elizabeth C. Ware and her daughter Mary Lee Ware financed the collection and presented it.
Though it was never completed, it contains species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use.
Making artificial flowers does NOT require________.
错误排除。根据第一段最后一句 “In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure” 可知，选项中， A 对应skill, B对应artistry，D基本是原文重复，只有化学没有提到，故选C。
[知识拓展] 一般而言，这样的题容易得分。需要注意的是，除了常识以外，答案在原 文的快速定位比较重要。同时，选项与原文词汇有近义表达，用低频词替换高频和中 频词也是命题技巧之一。
In the museum________were NOT found on exhibition.
错误排除。根据第二段提供的信息可知，博物馆专门展出彩色玻璃花朵模型，有 的是真实尺寸，有的为局部放大件，皆与模特无关。
[知识拓展] 与上一题类似，由于model有 “模型” “模特” 等意思，故 C 为干扰项，需排除。这类试题比较容易从原文中找到确切答案，故细心阅读即可。
The materials for making the artificial flowers and other plants do NOT include________.
错误排除。从第三段第三行开始，文章就玻璃花模型的原材料予以陈述，提到了 glass，colored，cold-painted以及metal oxides，唯独没有提到 wood。
[知识拓展] 可在原文中勾选提到的选项，然后顺利排除错误项目。
The founder of the Botanical Museum of Harvard University was ________.
细节识别。第六段第二行 “George Lincoln Goodale， founder of the Botanical Museum” 表述得很明确。
[知识拓展] 同位语对先行词进行解释、补充说明，表示全部或部分意义，从中可获取 附加信息。
Leopold and Rudolph Blaschka were________.
细节识别。第三段第一行 “The models in colored glass are the work of two artistnaturalists， Leopold 6laschka and his son Rudolph” 表明 Leopold 和 Rudolph Blaschka 的 身份是 artist-naturalists。
[知识拓展] 同位语表明身份，是非常有用的信息。
The purpose of the collection was to________.
近义表述。第六段第一句 “The intention of the collection was to have it represent at least one member of each flower family native to the United States” 说得非常清楚。
[知识拓展] 近义表述（paraphrase)也是命题常见的方向。准确定位原文是第一步，第二 步则是仔细鉴别。如本题represent对应copy， one member重复表达，every对应each等。
At the Botanical Museum of Harvard University, ________are NOT displayed.
错误排除。第七段提到了 “ 164 families of flowering plants ... fruits showing the effect of fiingus diseases ...flower parts and magnified details” ，分别对应选项D、A和C, 故排除B。
[知识拓展] 定位问题所指的段落，根据原文勾画处提到的选项，有利于快速排除错误选项。
Which of the following statements is true of the flowers in the Botanical Museum of Harvard University?
正误判断。全文一直在讲述玻璃花博物馆的建立，花朵模型的制作工艺和材料， 馆藏目的等，尤其在第二段第四行说明了 “They are made entirely of glass”，所以比较 容易选择。
[知识拓展] 正误判断与前面的错误排除不同，前者侧重找出正确答案，后者需要比照 原文一一排除，就精力分配而言，前者更经济。
The word “it” underlined in the last paragraph refers to ________ mentioned in the previous paragraph.
语篇衔接。第六段最后一句“financed the collection and presented it”存在句内回指，即 it 回指前面的the collection,第七段第一句重复it，属于词汇重复，复指the collection。所以，这里用了两种衔接手段。
An appropriate title for the passage should be________.
补充标题。就文章内容而言，各段依次讲述了人造花朵的用途、材料、制作工 艺，哈佛大学生物博物馆的玻璃花，玻璃花的制作历史与工艺，展览时间，馆藏展品新进展 （果树及授粉），馆藏目的与赞助人以及展品创新。显然选项C可以概括文章的核心内容。
[知识拓展] 标题是标明文章、作品等内容的简短语句，使读者了解到文章的主要内容 和主旨，讲究准确、鲜明、简洁、形式美和音韵美等。英语文章的标题以名词短语居多。
