问题    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 life-size 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. [br] An appropriate title for the passage should be______.
选项 A、Flowers Native to the United States
B、Materials Used for Artificial Flowers
C、An Extensive Collection of Glass Flowers
D、The Stories of Leopold and Rudolph Blaschka
答案 C
解析    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。
